flickering screen issue

Galaxy S6 has no signal, keeps saying NO SERVICE or EMERGENCY CALLS ONLY, other issues

Hello everyone and welcome to our #GalaxyS6 post for today. We have 11 S6-related issues in this one so hopefully you’ll find our suggestions helpful.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S6 shuts down on its own a few minutes after a starting

Firstly, the whole problem started from updating the firmware through Odin. The first firmware (Mashmallow from Sammobile) I downloaded didn’t work. Then I downloaded another version of Mashmallow from same site and that works. Next now is phone hangs on “Android is starting… Optimizing app x of xx”. After much battling like 2 days, clearing cache, factory reset from recovery mode and re-flashing the OS, phone was able to boot up. But never last 5 mins, keeps shutting down or restarting after boot. Tried SAFE MODE but it’s same. Working firmware G925VVRU4CPC2-Mashmallow and G925VVRS4DQE1-Nougat. Other Verizon firmware did not flash successfully, using the latest Odin. I’ve tried to do update OTA from Mashmallow but responded no update available and shuts down or restart. Only Odin upgrades the firmware to Nougat. I’ve also tried to get recovery from TWRP or CWM but no version for Verizon.

Another step was opening and detaching the battery for like 30mins and reconnects, stays a little longer then shuts down. I went ahead to change the battery from a working S6 edge, but it’s still same. Now I’ve done everything possible, but phone keeps shutting down or restart after successfully booting up in less than 2 mins. I need your candid help on this, probably it may be an hardware issue somewhere or still software issue. The device has never been rooted. Waiting patiently for your candid support. Thanks. — Shygo

Solution: Hi Shygo. By installing the software manually (flashing), we assume that you’re aware of the risks, one of which is happening right now. The best possible solution that you can try at this point is to flash the bootloader back to stock. If that won’t help either, you’re out of luck. You may have just bricked your phone for good.

Below are the sample steps on how to flash a bootloader. Exact steps may be slightly different for your phone model:

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Problem 2: Galaxy S6 app shows constant lag and slow video

Hello! I work with an online company. I communicate with lessons through an App. Today I updated to the Android Nougat on my S6. The main part of my job is to communicate with students through videos and slides in the App. First, classes with the new update were terrible, constant lag, video was slow, speech was delayed! Is there any way i can fix the issue immediately? This is my job and source of income. I have to get it fixed or i won’t be able to keep the job since i am in a different country and they rely on this. Please help me with a solution! thank you! — Kassen777

Solution: Hi Kassen777. Instead of looking for some device troubleshooting and solutions, we want you to focus instead to two possible areas where the problem may lie. The first one is connectivity. If you experience lag during video calls or when doing normal calls via the internet, there’s a chance that it can be connectivity-related. Make sure that you connected to a high-bandwidth wifi network or mobile data network. If you time your video calls or online classes during peak hours, or when your wifi network is strained by multiple users at once, you can’t expect to have a smooth online experience. Do some troubleshooting to determine if it’s a connection issue. If you’re in a mobile data connection only, it’s possible that the signal may be cutting off intermittently causing the lag or delays. If you’re on a wifi network, try to work with your internet service provider to try determine if you’re having some wifi troubles. The same thing goes if you’re in a mobile data connection.

The second factor you might want to check is the app itself. Well, there’s nothing much that you can do about it really other than to let the developer know of your troubles. But first, you must ensure that there’s no connectivity-related issue that affects how the app works. Some apps can’t work properly if a device internet connection is spotty so your first priority is to eliminate the possibility that your connection is problematic. If you’re absolutely sure that it’s not your connection, contact the app developer and let them about the problem.

Problem 3: Galaxy S6 internet connection is very slow when connected to wifi

Hi Guys, I am having the same issue as CL on the tread posted on (https://thedroidguy.com/2017/07/how-to-fix-wi-fi-issues-on-your-samsung-galaxy-s6-and-s6-edge-1047574) on Problem #7. Your suggestion is to look into the wifi connection. I think this is not the issue, especially on my case. I think it is the Samsung device. At my place there were 1 laptop, 5 phones (4 of them iPhones and mine the sole Samsung), all other devices can connect to wifi without an issue – can do streaming, browse Facebook,Youtube. You name it they can do it. I am subscribed to a high bandwith plan with my provider so it is really not an issue. Since I started downloading this upgrade to Android 7, everything went bad. As CL encountered as well, connecting to LTE works fine but when connecting to wifi it is soooooooo slooow to the point you want to throw your phone to the wall, especially when other people at come can enjoy what they are browsing / streaming on their phone.

in terms of Wifi congestion – even if I am the only one connected to wifi still the same sloowness.

Things I have done: 1. Reset my router – benefit of the doubt 2. Assign a static IP from my router to my phone – didn’t help 3. Use the DNS thing in my phone using advanced setting – didn’t help 4. Did factory reset on my phone – hoping it go back to Android 6 but no, it is still with Android 7 and yep didn’t help. Anything else you can suggest? — Allan

Solution: Hi Allan. We hope that by resetting the router, you mean the good old reconfiguration of settings and not a simple turning on and off of the device. If you are absolutely positive that there are no settings or modifications to the default settings of the router that may limit or throttle down the speed of your phone, then you may be right to say that it’s a smartphone issue after all. If you simply restarted the router though, we encourage you to reset all its settings to default by doing a factory reset on it, or by simply making sure that there’s no speed limiting configuration put in place that affects your smartphone. Each router has its own way how to change the bandwidth a certain connected device receives bandwidth so if you can’t figure that out, ask your internet service provider or the router maker for support.

In a smartphone, there’s a thing called network chip. This is one of the components in the motherboard that manages all networking-related tasks for your phone, be it mobile data, Bluetooth, wifi, among other similar functions. Like any other chip, it runs on a complicated interactions of firmware and hardware so it can also fail at times. Though your case is rare, it may happen if a variable or other factors happen to occur in an erratic manner. This can sometimes happen after installation of apps or a new Android operating system. If the only different thing you did was to install a new Android update and a factory reset did not fix the problem, you should consider reverting the firmware back to its previous version via flashing.

Also, you can try to check if your problem only happens when you’re on  your home wifi by connecting to other wifi network. If the same problem occurs even on a known fast wifi network, you may want to consider getting the phone replaced instead of flashing it.

Problem 4: Computers can’t detect Galaxy S6

Hello. I am not able to connect my Samsung to my laptop. I did not have problem with this before. Suddenly, out of nowhere my laptop stopped recognizing my phone. After I plug it in to computer I receive message: “USB device not recognized. The last USB device you connected to this computer malfunctioned, and Windows does not recognize it.” I am frequently updating my phone software. I recently purchased new laptop, which as well as old one does not recognize my phone. I followed few instructions about downloading drivers and keyes, but none of this ideas worked. What can I do? — Gosia

Solution: Hi Gosia. If two computers, one being a new one at that, are unable to read or detect the phone, that’s a clear indication that it’s a phone problem. Before you try to do some device troubleshooting, make sure that you try Samsung Smart Switch app first. Simply install the app to your computer before attempting to connect your phone to that computer again. If the same problem happens, factory reset your S6. Here’s how to do that:

  1. Turn off your Samsung Galaxy S6 Edge.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.
  5. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  6. Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  7. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Problem 5: Galaxy S6 active is dead, won’t charge or turn back on

Hi. I have an S6 active that I was charging and using the GPS maps at same time. It shut itself off and was dead after that. The phone was pretty hot, but not as hot as day before when I was using it and the screen letters on the GPS app got scrambled. I tried each of your steps from this website https://thedroidguy.com/2017/02/fix-samsung-galaxy-s6-wont-turn-firmware-update-troubleshooting-guide-1070186 Basically tried every type of boot up style which did not work. Also the charging indicator does not light up when plugged in. Not sure on the operating system it has. — Larry

Solution: Hi Larry. If your phone appears dead because it doesn’t charge or show any signs of life at all — sound notifications, vibrations, LED lights — then it’s most probably dead. Try using another known working charger first and see if that will recharge the phone. Otherwise, your only other option is to send it in for repair or replacement.

Problem 6: Galaxy S6 sent texts come out as gibberish for recipients

Hello. I am on a Samsung Galaxy S6 from T-Mobile. Recently, I updated to Android 7.0 but since then I have not been able to text my grandma or my mom. The texts come out as gibberish for them. They have old basic phones. At first I thought that may be the problem but my brother has the same phone and is able to text to them. Is there any way I could fix it for my phone? Thank you for your time. —  Kobe

Solution: Hi Kobe. Try to wipe the cache and data of messaging app you’re using and see if it works. Keep in mind that clearing an app’s data is the virtual equivalent of reinstalling the app so all your messages will be deleted. Make sure to back important conversations before doing it.

Below are the steps on how to clear an app’s cache and data:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.

If wiping the app’s cache and data won’t help, do a factory reset.

Problem 7: Galaxy S6 screen flickers, won’t power back on

I have a Samsung Galaxy S6 phone. The last update occurred on 3/1/17. No problems until last Friday 4/7/17, when it shut down and I could not bring it up again. I recharged it, turned it on, but got nothing except the two white lights on either side of the home button. On Sunday 4/9 I still couldn’t start it, so I did a soft reset and everything was fine until tried to bring it to life on Monday. Nothing happened, although I would get an occasional background flicker. Tried soft reset again; nothing. And still nothing. I have not tried all the other things you suggest because (1) I don’t trust myself and (2) without being able to see anything on the screen, I’m not sure how to proceed. Any suggestions? I did receive a phone call on it at some point. Thanks. — Joan

Solution: Hi Joan. The phone’s screen appears broken. We suggest that you don’t try anything else except to let a professional check it. We think the device can use a repair so letting a technician confirm that is your best bet.

You can’t fix an issue like this by doing some hardware button combinations, much so with software solutions. In fact, there’s no software solution that you can try in this one since the screen is blank. This may end up with a screen replacement so be sure to prepare some extra cash for the repair fee and part replacement.

Problem 8: Galaxy S6 does not charge, only charges when it’s off

When I plug my phone in to recharge, nothing changes on the phone. The “charge” icon does not appear visually, the phone does not make an “auditory recognition” of being attached to the recharge cable, and the phone will not take a charge. None of this happened like this previously, before today. I have had the phone for 1.5 years. If I “power off” the phone and plug the charge cord to it, the “lightning bolt” or “charging symbol” appears on the screen, and the phone will take a charge, but, I am reminded by the phone repeatedly (once every couple minutes), by an auditory (buzz) and visual “charging symbol,” until the phone is fully charged. So, I can charge the phone, but, I must turn the phone off by Powering it down, before it will take a charge. Odd!! I tried the Soft Reset to no avail. Any Advice? Thank you. — Mark

Solution: Hi Mark. Below are the things that you must try:

  1. Use another known working charging and cable. Try to use a good Samsung charger if possible.
  2. Recalibrate the battery by doing the following steps:
    • Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
    • Turn the phone on again and let it turn itself off.
    • Charge the phone without turning it back on.
    • Wait until the battery says it fully charged to 100%
    • Unplug the charger and turn the phone on.
    • If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
    • Unplug the charger the turn the phone on again.
    • Use the phone until you drain the battery down to 0.
    • Repeat the cycle once.
  3. Factory reset the device. Check the steps provided above.

If all these three items won’t solve the issue, there must be a hardware issue causing this charging problem.

Problem 9: Galaxy S6 not getting signal reception, keeps saying NO SERVICE or EMERGENCY CALLS ONLY

Hello Good day. I have been experiencing this “NO SERVICE” problem or “EMERGENCY CALLS ONLY” on my Samsung Galaxy S6 SM-G900F lately. I checked my IMEI and everything, but they’re all okay. The thing is I’m not really sure if i got this after I got the update or after I rooted the phone. I tried everything — wipe cache partition, factory reset multiple times, IMEI checking. I even tried installing other custom roms, but Everything failed. I also tried restoring its original Kitkat firmware but still the same issue. Right now, I’m using the Marshmallow update i installed manually. what can i do to get my service back? Please help me.oh by the way. My phone has a branded carrier when i purchased it. — Bingradiamoda

Solution: Hi Bingradiamoda. You should contact your carrier so they can re-activate your account or device again, whichever is necessary. Unless there’s an unknown software glitch that damaged the phone’s software permanently,  your carrier should be able to assist you with this problem.

Problem 10: Galaxy S6 stuck in boot loop after an update

I have a Samsung Galaxy S6. Recently it started getting stuck into a reboot loop. There was a recent OS update which, maybe by coincidence preceded this problem. I tried a soft reboot and also a hard reboot. Then I downloaded the repair assistant for Verizon from Samsung.com. It failed several times until I realized that USB 3 cable won’t allow it to work. I switched to a regular USB cable from another Samsung phone and the repair assistant worked immediately. However, the problem persists. When the charging cable is unplugged from the phone, it immediately starts back into the reboot loop.

At first I thought that the battery might be going bad but it has never had problems taking or holding a charge and even now behaving correctly. The phone operates well even if the charging cable is disconnected from a power source and the phone is left to the battery as the power source. The problem only occurs when the cable is detached from the phone. I suspect that the port could be physically damaged, however, I want to know before proceeding with a charging port replacement, is it possible that this is being caused by a software or firmware issue instead of a hardware issue? I would hate to replace a part only to find that it is not the real solution. thank you for your time and consideration. — Tim

Solution: Hi Tim. You’re right, you don’t want to commit to a repair procedure if the cause of the issue is software-related in the first place. That’s also the main reason why we always emphasize doing the basic software troubleshooting steps first instead of recommending repair right away. To know if your particular problem is due to bad software, make sure that you factory reset the device. With factory reset, all software settings are returned to their known, working state so if the problem returns after doing it, you’ll know that it’s not due to software at all.

It’s very likely that the problem is caused by a bad charging port so if nothing will improve after a factory reset, go ahead with repair.

Problem 11: AT&T Galaxy S6 drains battery power fast after switching to T-Mobile network

I have changed my carrier from AT&T to T-Mobile in CT, USA. We get not bad reception here as i live next to I-95. it has been only 3 days. And i can see my Samsung S6 battery is draining really fast for very minimum use of talk/text/yahoo mail app/Whatsapp.

I used to use those four apps majority of the time and my phone would last me more than 24 hours. but with the same amount of usage regardless of using 4G / wifi, i can see the difference between the battery drain AT&T vs T-Mobile. Does anyone have this issue or have encountered this one?  I have Android 6.0.0. please let me know if i can fix this problem by fixing something in my phone. I really got a good deal for T-Mobile and I would like to stick with them. Thanks. — Pinu

Solution: Hi Pinu. Dealing with a battery drain issue can be tedious, even for seasoned Android users simply because there are usually no obvious reasons for it. Your case may be the exemption though since you noticed it right after shifting to T-Mobile. That means that for whatever reason, your phone may now be working twice or more as hard for whatever reason. There’s really no telling why that happens though but it’s possible that your phone now demand more computing power everytime it’s connected to T-Mobile network. If you want to minimize battery drain, you should try to drastically change your usage habits. Some of the concrete things that you can start doing right away should include the following:

  • lowering down screen brightness to the lowest comfortable setting possible
  • utilizing power saving modes (Power Saving Mode and Ultra Power Saving Mode)
  • uninstalling unnecessary apps (the more apps you install, the higher the chance of battery drain)
  • turning off sync and auto updates for social network apps. These types of apps regularly communicate with remote servers to update contents so turning off their sync function or auto update feature should help.

Problem#1: Galaxy S7 won’t power back on

Hi there. As of this afternoon, I’m having problems with my Samsung Galaxy S7. I’ve been using the Phone for a few months now, and I have to say it’s been quite a disappointment because of a variety of issues that have plagued me. The significant being that since the latest update my phone will do random restarts every 2 or 3 days. When it does, it seldom boots up successfully in one go. Usually it’ll freeze in the middle of loading the Samsung logo and then just reboot by itself starting all over again. After about 10 – 15 times it will boot up successfully and I’m able to use to phone without any issues. I have to say that even doing a factory reset has not solved this problem. While this is annoying, it’s not something I’m willing to bring my phone to a technician over, since that would be quite a hassle for me.

The real problem I’m facing is what happened today. This afternoon I was using my phone without any problems, and when I was done I pressed the button that locks the screen and put it on my desk. About 10 minutes later I wanted to check the time and the phone is just dead. No response to anything. I’ve tried troubleshooting it with help of this website, but I haven’t been able to get the phone to boot. It’s very cold, much colder than it usually is so I assume it’s turned off. The battery isn’t the problem because it was freshly charged, 90%+ when I was using it. Connecting it to the charger also doesn’t do anything. No screen, no LEDs, nothing at all. Neither does connecting it to my PC. The phone also stays cold, while usually when it charges it warms up quite a bit. I’ve tried the Power + Volume Down button, Volume Up + Power + Home button, All buttons at once, all to no avail. I also probably have to note that a few days ago my phone fell for the first time, on a tile bathroom floor, cracking the backside glass but it seemed to function fine until today. Is there anything else I can do or should I just go to a technician? Thanks in advance. — Tony

Solution: Hi Tony. The only thing that you can do in this situation is try to restart the phone to other modes by doing the steps below. If the phone remains unresponsive and continue to fail to boot in any way, your only option is to send it in. there may be a hardware problem that causes the phone to fail to start normally, or to accept a charge.

And just to be sure, try to use another USB cable and charger to see if that will change anything. You can also check the charging port for any debris or lint that may prevent good contact with the charger. There may be a damaged pin in the charging port as well so if you can, try to do a closer inspection of the port.

For the benefit of other readers, here are the steps on how to boot your phone to other modes:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem #2: Accidentally dropped Galaxy S7 won’t boot back up

My S7 edge turned crashed and then auto-restarted. Then it got stuck on the Samsung logo for a while after which it completely shut down out of the blue. Now it’s refusing to turn on no matter what i do. I’ve tried all the combinations mentioned in the posts but it just won’t turn on in any mode. I’m originally from India and here in USA for 2 weeks. I just wanted to check if there’s any other troubleshooting I can do on my own before I go searching for a nearby Samsung service center. — Mayur

Solution: Hi Mayur. As mentioned above, if you can’t get the phone going after attempting to boot it to alternate modes, you need to ask assistance from a professional. The accidental drop must have damaged a component/s in the logic board or affected the battery so a thorough hardware check is necessary. If the problem started right after the phone was dropped, that’s an obvious indication that there’s now a hardware problem.

Even when enclosed in a “shockproof” case, an accidental drop can still cause severe damage to an electronic device like an S7 because most internal components are made of fragile materials can only absorb so much shock.

We highly recommend that you send it to a Samsung service center but if that’s not possible, you can always try the services of an independent service center as well.

Problem #3: Galaxy S7 screen is unresponsive and flickering

I have Samsung Galaxy S7 Edge purchased this year. It has flickering only at the bottom 1/3 of screen so nothing can be read in that area. I have tried the resets and rebooting, however, I’m unable to complete. The touchscreen is not responsive most of the time. This just started happening about 4 days ago.

Also on the reboot, when the little Android man appears, he falls down with an exclamation point in a yellow triangle.        — Croberts

Solution: Hi Croberts. Flickering and unresponsive screen are two of the common symptoms of a malfunctioning screen assembly. If you damaged the phone before either by exposing it to liquid or water or by dropping it, stop looking for solutions unless you are capable of fixing phone hardware problems (but we bet you’ll not contact us if you are). There’s no software tweak that you can do to fix hardware problems. Stop wasting your time and bring the phone directly to Samsung so it can be checked and repaired.

However, if your phone was never dropped nor exposed to water before noticing the problem, try doing a factory reset to see if there’s a difference. If nothing changes after resetting the phone, send it to a repair center.

Here’s how to factory reset your S7:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

NOTE: Factory reset will delete all user data so make sure to back up your important files before doing it.

Problem #4: Galaxy S7 apps stop responding | Galaxy S7 keeps vibrating in quick succession

Hey guys.  Firstly, I left my Galaxy S7 on charge overnight and it was working perfectly. When I woke up most of my apps stopped working. I got loads of pop ups saying; ‘Facebook is not responding,’ Twitter is not responding’ and so on. I tried to restart my phone and after I typed in my password for verification it is now stuck on a screen with an unlocked padlock with two half circles rotating around it.

It also vibrates on and then twice in quick succession every 4 seconds or so. Please let me know if you can help I’ve only had this phone for a week.

Also I selected Marshmallow on the Android Version but I’m not completely sure. Thanks for your time! — Zach

Solution: Hi Zach. Although smartphones are designed to automatically shut off charging functionality once the battery is fully charged, leaving a phone connected to a charger long after full charging has been attained may result to problems. We’ve encountered sporadic cases of phones failing to boot up after leaving connected to a charger overnight. For some reason, some smartphones can encounter problems when constantly left connected to a power outlet for long durations. Unfortunately, there’s not enough data that’s been collected to see a pattern to identify the cause of the problems in these cases. Our suggestion is to do your best to unplug the device from a power outlet when charging is done to avoid problems. We suspect that fluctuations in voltage is the culprit but other factors such as overheating or faulty chargers can be just as destructive. Investigating the cause in this case is beyond the scope of this article so let’s discuss some concrete solutions that you can try instead.

The first thing that you want to do is see if the problem is being caused by a bad system cache. To do that, you want to clear the cache partition. Here’s how:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Because you’re having problems with multiple apps at once, it’s very unlikely that the issue is on an app’s level. It must be something higher than that. It can also be due to some third party app so you also want to observe how the phone would work if it’s booted to safe mode. Safe mode blocks third party apps and services so if the errors won’t show and the phone will work normally, a third party app must be to blame. To boot your phone to safe mode, follow these steps:

  1. Turn your Galaxy S7 off.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. Observe the phone for a few hours to see a difference.

If nothing will change when your phone is booted to safe mode, you should consider doing a factory reset to check if there’s a software-level glitch causing the problem.

The vibration issue may or may not be due to hardware malfunction so if factory reset won’t eliminate it, contact Samsung or the store and have the phone replaced.

Problem #5: Water-damaged Galaxy S7 won’t turn on

Phone fell in water and was completely submerged in 6-8 inches of water for about 15 seconds. I was not there when the phone fell in. I do not know what the person did with the phone after getting it out of the water. I was given the phone shortly after and I stood it up on end (charge port down) on a towel. It appeared to be dry and has been about 6 days. I could not discern any water coming from the phone after I got it. It will not power on. Plugging the charger in today = nothing. Wireless charger indicates charging. I have not attempted to disassemble the phone other than to remove the SIM card. Unfortunately I was unable to do the rice or 99% isopropyl alcohol things and decided I would like as much a chance as possible to recover my phone from certain doom. Look forward to hearing from you, thank you for your time and consideration. — Daniel

Solution: Hi Daniel. Although the Galaxy S7 is a  water-resistant device, the protection may fail and allow some moisture to enter exposed areas. We’ve seen this happen a few times before, with the speaker the mostly affected component. We’ve heard of some S7s suffering from total boot failure after it was dropped in water or to high pressure liquid source like a faucet. Whatever the circumstances surrounding your case, the most pressing thing that you want to do now is to ensure that you have the hardware checked so it can be assessed if the phone has been permanently damaged or not. Because the Galaxy S7 is more difficult to disassemble compared to its predecessors, we recommend that you let a professional do the job for you.

Problem #6: How to unlock Galaxy S7 edge when PIN fails

Hey. I have a Galaxy S7 edge which belonged to my sister who recently passed away. We think there is some vital information on the phone due to the circumstances around her death.

We can’t get into her phone because of the PIN number lock. We have tried too many times now and every attempt locks you out for 1 hour. Hope there is some way you can advise or help us.

Many thanks.  — One stop

Solution: Hi One stop. The only way to unlock a Samsung Galaxy S7’s screen is to enter the correct PIN, pattern, password, or registered fingerprint. Even Samsung can’t help you unlock a phone if you forget your own screen unlock code.

If the previous owner enabled Smart Lock feature on the phone, you may be able to unlock by doing the necessary Smart Lock actions. Smart Lock options include:

  • On-body detection
  • Trusted places
  • Trusted devices
  • Trusted voice

On-body detection keeps the phone unlocked if it detects that you’re carrying or holding it. It requires that you unlock it once though so this is definitely not enabled.

Trusted places prevents the device from locking itself up if it detects that it is a place previously registered such as the home of the original owner. This feature must be set up first in order to work. Try bringing the phone to the owner’s house, office, or favorite place to see if it works.

Lastly, Trusted voice feature, as its name suggests, only works if the phone hears the voice command set by the original owner.

If you think there may be something important on the phone that can help you shed light on the original owner’s death, we recommend that seek help from your government. Law enforcement agencies can use special software to help you unlock the phone after the legality of doing so will be established.

Problem #7: Photos taken by Galaxy S7 camera app do not show in Gallery

This been happening a lot and I can’t seem to find the cause. When i take a picture it’ll show in the little window my picture but when i go to the gallery to get a full view of the picture it’s not there. So, I’ll go back to my camera and still see it in the little window and try to open to view the picture but it won’t show it to me. It’ll just show the picture previous to that one. This is been happening quite frequently. I don’t take a lot of pictures but this seems to happen every other other picture. Any help would be greatly appreciated. — A.J.

Solution: Hi A.J. We don’t think we fully understood what you’re saying here but if you have a problem with the camera app, consider resetting its settings to return them to default. If that won’t work, delete the app’s cache and data by doing the steps below:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

Galaxy S8+keeps shutting down on its own, screen remains black and won’t turn on, other issues

Welcome to our most recent #GalaxyS8 and #GalaxyS8+ article. This post addresses 8 more issues submitted by some members of our community. We just recently created an S8 troubleshooting page so make sure to visit it if you can’t find a solution to your own issue here.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S8+ keeps shutting down on its own

My Galaxy S8+ will reboot randomly and I would have to do a simulated battery pull. First time it took about 7x reset try. The next took 35 or so. My Galaxy S8+ is now locked into the logo screen when first boots. It will not power off. It happened around 450pm pst and it is now 158am. Can’t power down, it loaded 2x today for about 5 seconds then went to reboot and got stuck. I do not know the os system. — Bubblez_760

Solution: Hi Bubblez_760. This kind of problem does not happen in a normally working system out of the blue. Something must have happened to it causing the phone to shut off on its own. In some cases, a failed flashing or installation of custom software is the cause, while others may be due to physical damage. You haven’t given us enough information to help us identify the cause of the problem so there’s nothing much that we can tell you.

To try and fix the problem, consider doing a factory reset and see what happens from there.  Factory reset will return all software settings to their known, working state. If the cause of the problem is software-related, factory reset should help. Here’s how it’s done:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight “wipe data / factory reset.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, “Reboot system now” is highlighted.
  10. Press the Power key to restart the device.

If your phone continues to restart randomly, have it repaired or replaced.

Problem 2: Galaxy S8 black screen issue, won’t power back on

I was using my phone, and the screen went black. The phone is still responsive as sounds work when i press the volume up and down keys, but the display remains black. I tried the rest by pressing the power and volume down button, but the screen still remains black. The Samsung logo never shows up. — Eng51375

Solution: Hi Eng51375. Try booting the phone to alternate modes — recovery mode, safe mode, and download mode. If your phone stays unresponsive, or the screen remains black, bad hardware must be to blame. In this case, you should have the phone repaired or replaced.

Below are the steps on how boot your S8 to different modes:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem 3: Galaxy S8 camera app only shows button to take pictures

When opening the camera app, I get nothing just the buttons to take a picture. But no feedback or if I have taken pictures before. Screenshot included. I tried clearing the cache, uninstalled the update to Bixby vision (about an hour before this happened I had updated). And rebooted. Besides hard reset I am not sure what to do before that. —         Elizabeth

Solution: Hi Elizabeth. Are you using the stock or built-in camera app or not? If not, try using the stock camera app to fix the problem.

If you are having a problem with the stock camera app itself, try to wipe its cache and data. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, look for the camera app in question and tap it.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

If this won’t fix the issue, do a factory reset.

Problem 4: Voice call cuts in and out on Galaxy S8+

I recently purchased a Samsung S8+ and I’m experiencing a call quality issue. Last night, while in my car, i called my dad who had a horrible time hearing me so i disconnected the call. Then today when speaking to a friend, she stated my voice would cut in and out. I could hear her clearly. I’ve never had this issue and I’ve lived in the same location for over 13 years so I’ve never had a dead area in my house. I disconnected the line several times and even disabled my wifi on my phone and she still either couldn’t hear me or the connection was so bad she couldn’t understand what I was saying. Any ideas or suggestions to fix the problem or did i get a bad phone and do I need to return the phone? — Kathleen

Solution: Hi Kathleen. Try to record your voice using the phone’s recorder app or any app to see if the microphone is defective. After recording, listen to it and see if the audio sounds distorted. If it is, have the phone replaced.

If voice recording shows that the microphone is okay, the problem must be network-related. Contact your carrier and let them handle the situation for you.

Problem 5: Galaxy S8 won’t turn on

I’ve had my S8 plus for a month now and one morning it just didn’t turn on and just had black screen. I tried rebooting it and it only flashes some lines of light but it won’t respond, not even to the Home button. — Alan

Solution: Hi Alan. Please refer to our suggestion for Eng51375 above. Remember to seek for a phone replacement if your phone stays dead.

Problem 6: Missing icon for Hancom Office Mobile app in Galaxy S8

MY S8 COMES PRELOADED WITH HANCOM OFFICE EDITOR. HOWEVER THERE IS NO SHORTCUT FOR IT. IF YOU OPEN A SPREAD SHEET IT WILL GIVE YOU AN OPTION TO USE HANCOM OFFICE AS WELL AS ANY OTHER PROGRAM INSTALLED. CLICKING ON HANCOM WILL OPEN THE PROGRAM. FROM THERE YOU CAN CREATE A NEW DOCUMENT IF DESIRED. — Jsparky1

Solution: Hi Jsparky1. If you can’t find its icon anywhere, it may be categorized as a system app and thus, doesn’t need to have an icon displayed in the Home screen or in the Apps tray. To check if this is the case, go to Settings>Apps, tap More options icon (the three-dot icon) on the upper right hand side, and select Show system apps.

If it’s under system apps, you can’t create an icon for it in the Home screen or Apps tray. The app will only work if you try to open a certain file that can be opened by Hancom.

Problem 6: Galaxy S8 can’t send response to SMS Short Codes or Premium Numbers

S8 unblock sending messaged To Premium Numbers Problem: Silly question when ever, an example, Capital One or Verizon or any thing that is not necessarily a number, texts me a message about a charge, I have to respond with a confirm etc. I type the response, and then hit enter and this message comes up (to confirm that I want to send it.. not send it etc.. something about data etc). it does this to only those types of texts, I always hit ok. Well accidently today i hit no.. and i think I saw save and now when I go to respond to those type of texts i get messaged failed, I cannot respond. I do not know what I did or how to fix it. Can you help me? — Amberenglishudy

Solution: Hi Amberenglishudy. We don’t know what happened exactly so the best option for you right now is return the settings of both your messaging app and Contacts app to their defaults by clearing their data. Before doing so, make sure to back your messages and contacts up to avoid losing your contacts and precious messages (if any).

Here’s how it’s done:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, look for the camera app in question and tap it.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

Problem 7: Galaxy S8 screen is damaged, not working

Samsung Galaxy S8 touchscreen response but display screen super low contrast brightness almost not visible at all, flickering white rectangle that covers bottom 20% of phone at all times regardless if phone display is on or off, what do i need to replace? — Nhutnam.nguyen93

Solution: Hi Nhutnam.nguyen93. We suggest that you replace the entire screen assembly. It’s possible that the digitizer is okay while the LCD is not, but we understand how tricky it can be to separate the digitizer and LCD at times. To prevent damaging the digitizer during repair, simply replace the entire screen assembly.

Problem 8: Galaxy S8 screen remains black and won’t turn on

My S8 plus just cut off and the screen went black while I was trying to make a call. It had 65% charge. Have tried the resets in step one, nothing happens. Guess I will just have to take it back to the store, which is disappointing because I just activated it on April 22nd. — Stephanie

Solution: Hi Stephanie. This is definitely frustrating but if you can’t turn your phone back on for some reason, the best option for you right now is replacement.

If you haven’t tried it though, consider booting the phone to alternate modes first. See our suggestion for Eng51375 above.

Also, make sure that you try another USB cable and charger to see if it’s a charger issue.

Problem 1: Galaxy S7 edge won’t turn on normally, stuck in Download mode

Hello. I have a Samsung Galaxy S7 Edge. Last night I left my phone to charge with my Samsung fast charging adapter while my phone was 2%. It was plugged in for about 10 hours before i came to check on it in the morning. The LED light would not respond, none of the keys will respond to the phone and it just shows a black screen. Now what happens next is something that I have never seen before. 10 minutes after trying to solve the problem, a sky blue screen pops up with saying “press the up volume key to install and press the down volume key to cancel(restart)”. After seeing this I was hesitant to download it so I continued to press down and cancel. After not seeing any other possible solution I did press up and download it. I don’t remember what it said, but it was unfamiliar. I tried the many troubleshoot solutions like factory resetting or deleting cache but the phone will not respond in any way shape or form. — Antonio

Solution: Hi Antonio. Try to see if you can boot the phone to Maintenance mode. If it does respond and boots successfully, you may be able to restart the phone eventually back to normal mode. Below are the steps that you should try:

  1. Turn off your Galaxy S7.
  2. When powered down, press and hold the Power and Volume Down buttons at the same time.
  3. Continue holding these two buttons until you see the special Maintenance Boot Mode Menu.
  4. Let go of both the Power and Volume Down buttons.

If your phone remains unresponsive and only turns back on the current Download mode screen, you must then try to flash the bootloader back to stock. If that won’t work either, have the phone repaired or replaced.

For reference, here are the sample steps on how to flash a bootloader. Exact steps may be slightly different on your phone so make sure to look for a good guide online.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Problem 2: Galaxy S7 screen stays black, won’t show anything

Soft reboot works. It charges fully. I’m getting sounds and the digitizer works and haptic feedback. But i cannot get the screen to display anything. I can’t pull the battery because it’s an s7 and sealed and my glass would break if i pulled it apart. I’m pretty sure it’s the LCD that has failed but they are expensive. I’ve very tech savvy and have flashed Rom’s on other phones. Is there a way to get error codes or duplicate the screen on a computer to see what errors might come you. Any other solutions or help would be appreciated. Thanks. — Tyson

Solution: Hi Tyson. There’s no magic software solution to fix a bad screen. If the devices appears to receive notifications and shows indications that it’s turning on at this time, you have no other option but to send it in for repair. You can’t just plug it in and expect to be able to access the memory and do some software tricks to fix a malfunctioning screen assembly. If it’s under warranty, send it to Samsung and let them handle the screen replacement. Otherwise, let an independent technician replace the bad component for you.

Problem 3: Galaxy S7 won’t turn on after charging port got wet, keeps showing moisture detected error

Hi. My name is Kelsey. I have a Samsung Galaxy S7. I was in my pool taking pictures under water. When I do this i never put my ports under water. I always make sure to just put my camera under the water while holding my phone upside down. As risky as this is, i normally never have a problem. Well today my little cousin decided to blow water on me from his mouth and it got into my port. Not thinking anything of it, being the phone as water resistant, I just set my phone down. When I got to my charger later I plugged it up and it gave me the “moisture in port” message. I then took an air dryer to try and dry it off. ( I now know this is a really stupid idea). I then tried plugging it up and it gave me the “downloading do not turn target off.”Then i believe it went completely dead again because that screen turned off. When i plugged it up for what felt like the millionth time it came up with the battery with the lightning strike in the middle. But when it was actually charging in the past, I had little green bubble like things blinking up to the display battery ( I hope this makes sense) .They are not popping up now. It is simply just the battery with the lightning strike. Does this mean I need to start looking for another phone? please tell me no. Thank you in advance! Sincerely. — Kelsey

Solution: Hi Kelsey. Using an air dryer is not really a bad idea in this case as long as you take care not to apply too much heat to the phone. A Galaxy S7 is water resistant and it’s supposed to alert its users not to charge if there’s traces of moisture in the charging port. As long as the system detects moisture in that part, the phone will not charge at all. This may be the reason why you are no longer able to turn it back on. The battery may have simply run out of juice at this time. Make sure to dry the charging port by gently shaking the device. If the phone will never charge after you’re certain that the charging port is now moisture-free, contact Samsung for a repair or replacement.

Problem 4: Galaxy S7 won’t connect to wifi, Home button not working properly

Hi! I have a Galaxy S7 and have had no issues until recently. Within the past week, I have had 3 issues:

  1. trouble connecting to my Wi-Fi. I was able to solve this by turning on/off airplane mode several times.
  2. pressing the home button creates a screenshot – this is still occurring and restarting the phone does not solve this. This happens intermittently
  3. I keep getting a message out of nowhere to hold down the power button for several seconds to restart the phone.

I have not updated or installed any new apps. The phone says there is no update needed. I just find it odd that I have had 3 major issues in the past several days after not having any problems in the last two years. Thanks for any help you can give. — Alison

Solution: Hi Alison. If these issues appear out of nowhere, something drastic must have happened to the software or hardware. If your phone was exposed to water or elements, or was physically impacted after an accidental drop, bad hardware may be to blame. In this case, you would want to stop looking for a solution and simply have the phone checked. Only after a thorough physical check can a technician tell if repair will be able to fix the problems or not.

If your phone was never dropped or got wet before, do a factory reset and see what happens from there. If this is a software-related problem, your issues should not occur right after a factory reset (when there are no third party apps installed).

If the phone works normally after a factory reset but starts to act erratically after installing back your apps, one of them must be to blame. You must identify the problematic app using elimination process.

To factory reset your phone, follow these steps:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

Problem 5: Galaxy S7 can’t transmit sound in calls or text

Hello. I have an unlocked Samsung Galaxy S7 which I received from my brother and I am on the Freedom mobile network in Ontario Canada. A year or so ago when I received this phone I was quick to discover that it is not compatible with the wind mobile (now freedom) frequencies. I had to spend 30ish Canadian to have a man at a booth install a fix for this as nothing I tried worked (installing modem files etc). It worked fine for a while until one day my phone stopped allowing me to hear and transmit sound in phone calls or even messages. I have tested the microphone using Facebook messenger and voice recorder and it works just fine! I want to know if there’s a way for me to fix this frequency problem on my own as I should not have to spend 30 dollars to fix this again when neither my phone maker or service provider will help me in the slightest. — Kristian

Solution: Hi Kristian. We don’t know what you mean exactly by the “frequency problem” you’re referring here but we assume the person who fixed your device tweaked the software. Technically, if we say a device is not compatible with a network’s frequency, that’s because a phone’s radio can only work with limited frequency bands. You can’t just change the operating frequency bands of a device to make it compatible with the frequencies of a certain network.

As much as we would like to help you, there’s nothing much that we can do about your issue. You must let a technician physically check the device so he or she can determine what software changes needs to be done.

Problem 6: Galaxy S7 slow when opening text, videos won’t play, keyboard not working properly

I have a Samsung Galaxy S7 and have never had issues until this last month. It is very slow to respond when opening messages from text or messenger. Videos won’t play through and keep pausing and I have to keep pressing play again. Sometimes keyboard stays on screen longer than messages screen so have half keyboard/ half home screen showing. I currently run 360 security app on my phone but have been told I don’t need this or any antivirus, is this true? Help please. — Jessedwards

Solution: Hi Jessedwards. Instead of fixing issues individually, we suggest that you do a factory reset instead to try and fix all of them. To see if a problematic app is to blame, you also want to make sure that you don’t re-install apps right away after a factory reset. This will allow you to check if there’s a difference when the phone only runs a clean version of Android and when there are apps installed. To factory reset your S7, follow these steps:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

Problem 7: Galaxy S7 stuck in endless boot loop

The phone is stuck in an endless loop of restarting and then getting stuck on the Samsung logo. I have tried everything on your blog related to this but this isn’t going away. If I press the volume down key after the Samsung logo appears out just restarts.. Doesn’t move into the android logo but gets stuck again. Can you please help? — Tejraj P

Solution: Hi Tejraj P. Please see our suggestion for Antonio above. If the phone won’t respond or remains stuck in boot loop, there must be a hardware problem causing it. In that case, have the phone repaired and replaced.

Problem 8: Galaxy S5 and S7 incoming calls are being diverted to voicemail

My partner has a Samsung Galaxy S5 and I have a brand new S7. We both have the same problem. We are with Plusnet and when we are set to connect automatically to 2G/3G & 4G our phones will not receive phone calls but go straight to voicemail. — Lorraine.braddon

Solution: Hi Lorraine.braddon. This is an issue that only your carrier can fix so we suggest that you let them know of this issue as soon as possible. There must be some misconfiguration in the device or in your account that forces incoming calls to your voicemail.

In some cases, users may forget that they may have enabled call divert feature on their number. Be sure to talk to your carrier technical support team about it so they can walk you through how to check it.

Problem 9: Galaxy S7 speaker volume is low during calls

I bought a phone on eBay. Finally got it to connect to our wifi and it seems to work OK but I can barely hear the caller when I receive calls. I’ve tried increasing volume but that just makes the ringtone etc louder. I’m not super technical. My brother says “aol” stands for all old ladies… Can this be fixed? I’d appreciate any help. Thanks. — Ashley

Solution: Hi Ashley. If the volume problem only occurs during calls but not in other functions that require the loudspeaker such as when playing music or videos, then the reason must be on the software side. Try to use a different app for calls like Facebook Messenger or Google Hangouts. There are a ton of other similar apps in Google Play Store so take your time in testing them out. If the problem persist after using multiple apps, consider doing a factory reset. Refer to the steps above on how to do it.

On the other hand, if said problem happens whether you’re in a call or not, it’s probably due to a faulty hardware, particularly a malfunctioning loudspeaker. As a workaround, you can try using a wired or wireless headset during calls. If you don’t want that, have the phone replaced.

Problem 10: Galaxy S7 screen flickers when brightness is set to low

Hello! I have a Samsung Galaxy S7 and lately whenever i turn the phone brightness lower than halfway up the bottom 1/3 of the screen flickers. The flickering persists in any app and I’ve tried soft resetting. what might this be? — Matt p.

Solution: Hi Matt p. An issue like this is usually caused by bad hardware. Try a factory reset and see what happens after that. If the problem stays, get a phone replacement.

What to do with your Samsung Galaxy J5 with screen flickering issue [Troubleshooting Guide]

The screen flickering issue with your Samsung Galaxy J5 might be due to a firmware or hardware problem. We really can’t pinpoint what the cause is or know what the problem is all about until we troubleshoot your phone. We have received quite a lot of complaints from our readers who reportedly experienced having the screen with their phones flicker at some point but it doesn’t necessarily mean all of those cases belong to the screen flickering issue.

There are times when the screen flickers when you’re opening an app or using a native function. If the flickering only happens while you’re using a specific app, then you might be facing an app problem and not necessarily a screen flickering issue. We will walk you through in troubleshooting your Galaxy J5 that’s plagued with this problem. Let’s try to look into every possibility and rule them out one by one until the issue is fixed. So, if you’re one of the J5 owners that’s experiencing this problem, then read on as we might be able to help you.

Before anything else though, if you have other issues with your device, then visit our Galaxy J5 troubleshooting page for we have already addressed several common problems with this phone. Odds are that there are already existing solutions to your problems so just take time finding issues that are similar with yours. If you can’t find one or if you need further assistance, feel free to contact us by completing our Android issues questionnaire. Please provide us with as much information as possible so that it would also be easier for us to troubleshoot the problem. Don’t worry as we offer this service for free, so all you have to do is give us sufficient information about the problem.

Step-by-step guide to troubleshooting Galaxy J5 with screen flickering issue

It is important that we know what this problem is all about so that we can try to find a solution that might just fix it. So, go through the steps below and see if you can solve this problem without any help from a tech but before that, here’s one problem we received from our reader…

Problem: Hello guys. I’m not sure if you have already encountered this problem but the screen of my Galaxy J5 changes brightness from time to time but it happens in a split second; the display dims then goes back to original brightness then dims again. There are also times when it displays some kind of static with lines running from the bottom to the top of the screen. I don’t have a clue why this is happening so if you could provide some steps on how to fix it, that would be great.

Troubleshooting: The course of our troubleshooting would be to rule out the possibility that this problem is caused by some app or firmware related issues. If at the end of our troubleshooting the flickering never stops, then we can say it’s a hardware problem and we can only do so much about it considering the fact that we might void the warranty of your phone just by unscrewing one of its screws. Now, here’s what you need to do on your end…

Step 1: Perform the battery pull procedure

This is a very effective method to address minor firmware and hardware related glitches. Take note that glitches happen all the time and flickering screen is just one of its symptoms. This procedure is safe for your phone and data and the only thing that might be changed after this is the time and date. Here’s how you do it…

  1. Remove the back cover.
  2. Pull the battery out.
  3. Press and hold the Power key for a minute or two.
  4. Place the battery back in.
  5. Attach the back cover.
  6. Turn your phone on.

Now observe to know if the screen is still flickering or not.

Step 2: Observe your phone in Safe mode

Starting your phone up in safe mode alone doesn’t fix the issue but it will surely give you an idea what’s causing it. Assuming the problem is due to a third-party app, then the screen won’t be flickering while your phone is in safe mode. While in this environment, all third-party apps are temporarily disabled so you can actually isolate the problem and do necessary procedures to fix it. Now, here’s how you boot your phone up in safe mode:

  1. Turn the device off.
  2. Press and hold the Power key past the screen with the device name.
  3. When ‘SAMSUNG’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see ‘Safe Mode’.

Assuming the display doesn’t flicker in this mode, then move on to the next step, otherwise, skip to step 4.

Step 3: Find the app that’s causing the problem and then reset, uninstall it

The challenging part in this step is finding the app that’s actually causing the problem especially if you’ve already installed a lot of applications. But start from apps you installed prior to the problem and deal with one app at a time. If you already have a suspect, try to reset it by clearing its cache and data, then try to update apps that need to be updated and lastly, uninstall the app that you think is causing the problem.

How to clear app cache and data on Galaxy J5

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap Application manager.
  5. Tap the desired application in the default list or tap MORE > Show system apps to display preinstalled apps.
  6. Tap Storage.
  7. Tap Clear data and then tap OK.
  8. Tap Clear cache.

How to update applications on Galaxy J5

  1. From any Home screen, tap the Apps icon.
  2. Tap Play Store.
  3. Tap the Menu key and then tap My Apps. To keep your apps automatically updated, tap the Menu key, tap Settings, and then tap Auto-update apps to select the check box.
  4. Choose one of the following options:
    • Tap Update [xx] to update all applications with updates available.
    • Tap an individual application and then tap Update to update a single application.

How to uninstall apps from your Galaxy J5

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Applications.
  4. Tap Application manager.
  5. Tap the desired application
  6. Tap Uninstall.
  7. Tap Uninstall again to confirm.

Step 4: Delete all system caches so they’ll be replaced

If the phone still flickers in safe mode and if you recently updated it, then it’s very much possible that the some corrupt caches are causing the problem. To rule this possibility out, you need to boot your phone up in Recovery mode and then wipe the cache partition.

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. Press the Volume down key to highlight ‘yes’ and press the Power key to select.
  8. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

If the problem still persists after this, move on to the next step.

Step 5: Backup your files and data and reset your phone

After doing all the steps above and your phone’s screen is still flickering, then you need to reset your phone to rule out the possibility that the problem is due to a firmware issue. This is also the last troubleshooting procedure you have to do because if the problem still occurs after this, then you really have to let the tech handle it for you if you can’t stand the flickering.

Before the reset, make sure you backup your files and data as they will be deleted, then disable the Factory Reset Protection so you won’t be locked out of your phone after the reset.

How to disable Factory Reset Protection on Galaxy J5

To turn off the device anti-theft, you will have to sign out of your Google ID on the device and elect to not sign in with a Google ID into any Google services. Once you sign in with a Google ID to any service and setup a PIN, password or fingerprint lock, you are automatically turning on anti-theft. To sign out of your Google ID, follow these steps:

  1. From the Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Accounts.
  4. Tap Google.
  5. Tap your Google ID email address. If you have multiple accounts setup, you will need to repeat these steps for each account.
  6. Tap More.
  7. Tap Remove account.
  8. Tap REMOVE ACCOUNT.

Two ways to reset your Samsung Galaxy J5

This is how you reset your phone through the Recovery mode…

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.
  10. Press the Power key to restart the device.

And this is how to reset it from the Settings menu…

  1. From the Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Backup and reset.
  4. If desired, tap Back up my data to move the slider to ON or OFF.
  5. If desired, tap Restore to move the slider to ON or OFF.
  6. Tap Factory data reset.
  7. Tap Reset device.
  8. If you have screen lock turned on, enter your PIN or password.
  9. Tap Continue.
  10. Tap Delete all.

I hope this troubleshooting guide helps.

Galaxy S6 screen keeps flickering when auto lighting is enabled, calls keep dropping, other issues

Here’s another #GalaxyS6 post for you. As usual, we bring you a number of S6-related problems reported to us during the last few days. We’re looking forward to posting more of the same articles in the near future so keep watching for them.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S6 can’t transfer photos to computer

Two problems: 1) Not able to transfer photos using MTP or PTP after update, and 2) No audio transmit on phone calls after factory reset.

For over a year I have transferred photos from the S6 to Mac using the MTP option under charging notification when using the USB/charging cable that came with the unit. After an auto update a few months ago, this option is no longer available.  Now when I click on the charging notification I get a page with battery options for power saving. I also get a message saying the phone is charging slowly and to use the original charger. I attached another S6 phone using my cord and my Mac and was able to transfer the photos as before.

I tried an online chat with Verizon and for over an hour the agent walked me through a number of troubleshooting tests, checking all the settings, activating USB debugging, soft reset, etc. He told me the last resort would be a factory reset and that I needed to backup my photos and contacts before doing that. Yesterday I went to the Verizon Corporate Store and for three hours we tried everything including the backup and factory reset. The phone still has no MTP or PTP options page when clicking on the charging notification. Under settings, Developer Options, the USB configuration is set to MTP. I realize I can use the Google Cloud but it is very cumbersome and time consuming to upload and download photos that way.

When I returned home after the factory reset, I received a phone call and they could not hear me, there was no audio transmit. I again used the Verizon online chat for two more hours of testing to no avail. The only way I can use the phone now is on speaker phone. The voice recorder also works fine. They tell me I need a new phone. Could the factory reset have caused the new problem?

Thanks for any information or suggestions you may be able to add. — William

Solution: Hi William. If both problems occur after doing a factory reset (via Recovery mode) and without any apps installed, their most likely cause is bad firmware. One of the reasons (though it’s rare) for problems after installing an update is poor coding. This means that the update you installed was built inefficiently, hence causing bugs to a system. If this is what happened in your case, there should also other users affected by it since updates are released in batches. The thing is, there’s really nothing much that an end user can do about it. You can either demand for a new replacement phone and hope that it doesn’t cause you any problems at all come another update, or you can just ignore the problem for now and wait until it’s patched.

If your carrier can provide a replacement device, we recommend that you go for it.

Problem 2: Galaxy S6 screen keeps flickering when auto lighting is enabled

Hi Samsung. Recently my Samsung Galaxy S6 screen has begun flickering in low light. It continued to do so for a few weeks until it became increasingly bad. In the morning when I woke up to grab my phone I’d press the middle button and the screen would be black. It didn’t matter how many times pressed it, the screen would remain black.

Once I turn the auto lighting off it is fine. However, when I return it to auto it begins to flicker in low light again. I have done a factory reset and taken it to many service centres who are unable to help me as they do not understand the issue.

I have read many concerns about this issue on this page in the same way and all of the responses tell me to do what I have already done. Please could you help me with this!  — Sofiadevita97

Solution: Hi Sofiadevita97. We’ve heard of this issue for some time now but we still can’t figure out if it’s a glitch in certain firmware versions, or if it’s caused by bad hardware in some batches of this device. There’s no official word from Samsung or from Google about it so we can’t say it’s a known issue. Like in some odd cases before, it’s possible that there’s a certain batch of these devices that have this problem. We are positive though that it’s not a common issue, at least, for Galaxy S6 devices if we take into account the millions of such devices in the wild.

Like in most isolated cases, the direction that you should take is to exhaust all possible software troubleshooting including factory reset and flashing (if you can manage). If you want to go with flashing, start by installing the original firmware that came with it (most probably Android 6.0). If these software troubleshooting won’t fix the problem at all, have the phone replaced.

Problem 3: Galaxy S6 calls keep dropping

Hi guys. I have Samsung Galaxy S6 and while on the phone, talking to someone, the call will either drop or will go to hold itself. The sensor is fine, I tried to check if the screen goes black when it’s by my ear. I am definitely not pressing any button during call, reception is always good, plus this is happening to me on my second S6 already. It’s sooo frustrating, because sometimes I am talking to someone for 30 second without knowing they can’t hear me and then they can hear me again. Sometimes call just drops.

I tried to do soft and hard reset, update software, even pressing the home button during call to go to homescreen, just to make sure I’m not touching hold button. I think I tried everything. Thanks for your help guys!! — Alex.voznak

Solution: Hi Alex.voznak. If the proximity sensor works fine, then your next move is to check whether it’s due to a bug in the phone app you’re using. Make sure that you wipe it’s cache and data. Here’s how it’s done:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.
  6. Tap Clear Cache button first and observe how calls work afterwards. If nothing changes, do the Clear Data option.

Should the issue remain after doing the two steps above, you should then try to see what happens if you use another phone app like Facebook Messenger, Google Hangouts, or any similar app.

If you tend to install apps without checking their sources, it’s possible that a bad third party app is behind the trouble. Try to observe how calling works when the phone is in safe mode. Safe mode blocks third party apps and services so if one of the apps is responsible, the issue won’t occur. Below are the steps on how to boot your phone to safe mode:

  1. Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  2. Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  3. Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  4. You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

If the problem continues even when you boot your S6 to safe mode, you should then try a factory reset. If that won’t fix it either, contact your carrier for support.

Problem 4: Galaxy S6 screen won’t respond, stays black

I have had my Samsung Galaxy S6 about 2 to 2 and a half years. Just Saturday night while I was at work, I pulled my phone out of my pocket to check the time and the screen was fading. Mind you, I stand at work all day long with my phone in my pocket and had not dropped it at all that day. I have dropped this phone many times in the past and it’s never done this, and only one drop a year ago resulted in multiple cracks across the back of the phone. When I woke up the next morning, Sunday (6/18/17), the screen had completely went out. It was on vibrate before it went out so I can still get calls and hear that messages are coming in, but I can’t see anything. The only things that still work are the LED lights at the top and bottom of the phone. My insurance is void because of the cracks and I have tried all the different methods of trying to get it to cut back on (hold down the volume, power, and home buttons in different combinations), but NOTHING is working. The phone restarts but nothing happens to the screen. I don’t have any alternatives and money’s tight so the phone probably won’t be paid off and upgraded any time soon. Are there any other ways to get the phone screen to work again, or am i just screwed? — Lauren

Solution: Hi Lauren. If the phone screen remains unresponsive and nothing comes out positive when you try all hardware button combinations, you can assume the screen assembly is broken. To fix that, you must send the phone in. We know a paid repair may not be an easy option for you but it’s the only way to fix a bad screen. There’s no software magic or hardware button combinations that you can perform to fix a malfunctioning hardware.

Problem 5: How to unlock FRP-locked Galaxy S6

I rooted my S6 because I wanted SuperUser access to use an interactive shell. I did a factory reset beforehand and then I set up my Google account after the root was completed so I could have access to the Play Store to get the apps I wanted. My S6 had been having battery issues (I recently upgraded to S8) and it died. When I try to start it, I get the “Custom Binary Blocked by FRP lock” error and the phone won’t turn on. I’ve read that FRP is automatically turned on when a google account is connected, and that is why I’m getting the error. Is there any way to get around the FRP lock so my phone will turn on? — Kalebschulz

Solution: Hi Kalebschulz. There’s no official workaround if your phone gets locked due to FRP. You must enter the correct Google account credentials in order to unlock the device.

Some users were reportedly able to unlock an FRP-locked device by flashing the firmware though we haven’t tried it so we can’t verify them ourselves. Try to visit Youtube and find videos that demonstrate workarounds for this issue.

Problem 6: Galaxy S6 stuck in boot loop after an update

In May, my daughter allowed a recent system update to run on her phone, and now it won’t work anymore. She doesn’t know the version, but it was the update it forces us to do in May. (Note: My Galaxy Note 5 hasn’t been the same since that update either, but I am still able to use my phone after a successful factory data reset.) It goes from the Samsung Galaxy S6 screen to “Installing System Update” w/Android guy screen to error screen with yellow triangle/black exclamation point/dead Android guy screen, in that order. She tried to factory reset, but it wasn’t successful. Acted like it was restarting, but then different error screen than this one, then shut off and started this endless error loop. Sure would love to have some help with this! — Scopeland062611

Solution: Hi Scopeland062611. If the phone started having the problem after a carrier-provided over-the-air update was installed, then the best thing option for you right now is to let your carrier handle the situation. It was their update or firmware that caused the problem after all. They should either fix the phone, or replace it.

If carrier repair or replacement is out of the question, you can try flashing the bootloader. Bear in mind though that this procedure may not work at all and can potentially brick the phone for good if not done correctly. If you haven’t tried doing this before, you should do research first so you’ll be familiar with the steps. Below

are the steps on how to flash a typical bootloader. The exact steps for your phone may be slightly different so make sure to find a good guide on how to do it properly.

The steps below are only for demonstration purposes:

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Problem 7: Galaxy S6 screen remains black, won’t turn on

Well you see yesterday my phone was working absolutely fine but though during when i was sleeping i charged as it was dead aka out of battery. The next morning i woke up and phone had a black screen with nothing responsive and the phone was extremly hot and somehow i was unable to turn on. I’ve tried methods on Youtube be draining the battery and charging again but it dosent work. Also when i charge the phone starts to heat up but i can’t turn it on and nothing shows up at ALL. I’ve attempted to use other chargers and different location but it hasn’t worked. I’ve tried not charging it for a day and charge it once again it still doesn’t work and i honestly think it’s a physical problem as it was working fine but when i charged it and woke up it didn’t work. So how am i suppose to fix this? — Anthony.sao

Solution: Hi Anthony.sao. Try to see if you can turn the phone on to other modes so you can do follow up troubleshooting. If your phone stays unresponsive, send it in for repair or replacement.

Below are the steps to turn the phone on to other modes:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the Samsung Galaxy logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem 8: Galaxy S6 bottom screen has white snow

I was charging my phone on the Samsung WIRELESS charging pad like I’ve always done and when I woke up it had a screen that I’ve never seen on the front of it. 3/4 of the screen from the top is a dark burgundy color with it saying “Samsung Galaxy S6 Edge Powered by Android and the bottom other half of the screen is covered in white snow…the kind of white snow that would be on an old TV screen. This is new.

Also when I plug it in manually to charge…the same color screen comes up with the white snow at the bottom of it but it has an empty battery charging icon on it instead. Both screens that appear like that only stay on for a couple of seconds and then it goes back black. SIDE NOTE…I’m not sure what operating system is on the phone.         — Sim0ne99

Solution: Hi Sim0ne99. Try to restart the phone to Recovery mode (steps given above) and see if the screen issue stays. If it does, that’s a confirmation that the screen assembly is not working right. In that case, you should contact Samsung or any relevant party so it can be repaired or replaced.

Problem 9: Galaxy S6 edge keeps freezing and turning on and off

I have been having some issues with my Samsung S6 Edge lately. it started freezing up then kept turning on and off then it just turned off and won’t turn on. I followed the steps on your website and got it to turn on. it works for a couple days and just turned off by itself and would not turn on, in either safe or recovery mode. i had to take it to a technician who opened it up and applied a solution to the board. it started working fine until it turned off on its own yesterday. I have managed to get it started again but i need to rectify the problem. I seems to me to be a software issue. Would it be a good idea to flash the phone or can you advise what i should do. Please to hear from you soonest.  — Jeffrey.browne

Solution: Hi Jeffrey.browne. When it comes to Android troubleshooting, the most that you can do is usually a factory reset. If you’ve tried that without any positive result, you can also try to flash it, if you can manage it. Keep in mind that flashing can potentially brick the device so you want to make sure that you know what you’re doing.

We don’t think this is a software issue though so if there’s no change after a factory reset and flashing, consider a phone replacement.

Problem 10: Galaxy S6 edge won’t turn on

Hey Droid bro. I have Samsung Galaxy S6 Edge sm-g925f. It was on marshmallow update when I bought it. While using it, it randomly crash and hangs on but a normal restart used to solve the problem. But yesterday when i opened up camera app it just froze and when i tried to restart it, the screen went black and since then nothing shows up on the screen . I tried your troubleshooting guide but no help. I tried booting up in recovery mode and in download mode but nothing shows up. I plugged into the charger but no signs of luck. I am really worried. I shall be very thankful if you help me out. Thanks. — My7h5542

Solution: Hi My7h5542. If your phone won’t turn on, there’s obviously nothing much that you can do. The only suggested troubleshooting in this case is to try turning on the device to other modes — Recovery mode, Download mode, and Safe mode. If the phone refuses to boot up to any of them, you must send it in. Your phone needs to be checked so you’ll know if it can be repaired, or if a phone replacement is needed.

How to change the appearance of Galaxy S7 after updating to Android Nougat, other issues

Hello everyone and welcome to our #GalaxyS7 article for the day. We’ve been receiving more S7 issues in the past weeks so we’re gradually increasing the frequency of our published articles. If you can’t find a solution for your issue here, be sure to keep watching for more S7 articles in the coming days.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S7 can’t read encrypted SD card

The phone isn’t reading my encrypted Micro SD card. I was using it normally and then I tried to open a picture in the Gallery and the album wasn’t there. At first I thought I was in a different root but then I realized that the phone wasn’t reading and opening the information in the SD. I turned off the phone, removed the Micro SD and mounted on my laptop. I was so happy to see all my albums and files in the SD. I tried to open any file BUT surprise, my info is encrypted. I return the SD to the phone, turn it on but nothing. If I go to the security menu on my phone / Encrypt SD card, I have the 2 options: decrypt and encrypt. If I try to decrypt the card, the process start searching and then crash. So? What can I do? I can’t format the card, but I can’t format the phone either so what’s wrong? — Juan Pablo

Solution: Hi Juan Pablo. We have no way of telling what exactly is wrong why you have this situation. All we can do is speculate but unfortunately, that won’t fix your issue at all. To be honest, there’s really nothing much that you can do. Perhaps, a software glitch hit something that changed some operating system configuration. Again, we can’t be so sure about that. Doing device troubleshooting like factory reset is a big no-no so that leaves you with SD card reformat option, which obviously deletes all your data. Inserting your SD card in another phone is definitely out of the question.

We are not aware of any effective third party recovery tool out there but if you think your data is worth a few hundred dollars of investment, consider using the services of companies that specializes in data recovery. There’s no guarantee that they can successfully access your files so be ready to part ways with your money if that happens.

Try using Google to look for reputable companies that can help you. Be sure to let them know of the entire situation so they can give you advise before paying up.

Problem 2: Galaxy S7 won’t turn back on after used under water

I took underwater photos with my Galaxy S7 phone (it was under water for about 3 or 4 seconds and it was just 3cm under the water). I don’t know if that matters but it happened in Greece and the water has much salt in it. After I went out of the sea I noticed that the phone doesn’t work correctly and doesn’t accept my commands. I put it next to me in order for the sun to dry it. It didn’t work so I got home and wrapped it in a towel and waited for about an hour and it didn’t start to work. After all, I decided to leave it on the shelf with the SD card out of it because there was nothing left that I could do in that situation. We are on a vacation and I can’t take it to a technician. Can you please tell me if I can do anything else because after everything I have done the display still doesn’t work. I also restarted it from the power and the volume down buttons two times because it can’t shut down. It just doesn’t accept any of the commands I try to give it. I’ll be very thankful if you give me any advise for that problem. — Elizabeth

Solution: Hi Elizabeth. Although a Galaxy S7 is rated as water-resistant, it’s not fully water proof. Dunking it in free flowing water might still damage it and we’ve already seen a lot of such cases before. Not exactly a confidence builder for an expensive device marketed as almost water proof.

Anyway, if your phone is dead and doesn’t respond to any hardware button combination at this time, there’s nothing much that you can do. The best thing that you can do right now is to wait until you get home so you can send it to Samsung. The hardware must be checked so it can be assessed if repair can fix it.

Problem 3: How to customize notification settings in Galaxy S7

I just got the Galaxy S7. Yesterday, when my screen was locked/black, it showed the date, time and battery level as well as any notifications from messaging and emails. Today the messaging and emails don’t show up. How do I get that back?

Also, I don’t like that when a text come and I unlock the screen the text is showing up in a large box in the middle of the screen. Is there a way to change that? — Emily

Solution: Hi Emily. To fix these issues, you must customize how each app shows notifications. Below are the steps on what you need to do:

  1. Open the Settings app.
  2. Tap Notifications.
  3. Look for the app you want to turn notifications for and tap it. This will turn on notifications for this app.
  4. Tap ADVANCED at the upper right hand side.
  5. Select the app you want to set the notifications for.
  6. Select the setting you want. The explanation for each option should be easy to understand.

Problem 4: Galaxy S7 drains battery power faster when using AT&T SIM card

I’ve had my Samsung Galaxy S7 for over a year with T-Mobile as my carrier. Soon I will be moving from California to Iowa. The location in Iowa has no T-Mobile coverage, so prior to moving, I have decided to switch carriers to AT&T. Herein lies my problem. I used to get upwards of 24 hours on a full battery charge. The very moment I switched to AT&T, I noticed a serious and rapid drain on my battery and I can literally watch the % go down. I am lucky to get 3-4 hours now, and have it constantly attached to my portable charger.

I have not changed anything on my phone, no updates, no new apps, no settings adjustments. The ONLY thing I did was replace my T-Mobile SIM card with the new AT&T SIM card and that is all.

Of course, the AT&T reps deny that my battery issues are caused by their towers or switches, and instead, suggest I buy a new phone (or battery at the very least). I checked Battery Usage and I show only a couple of apps using less than 3%. Nothing out of the ordinary. Any help would be greatly appreciated. Thanks. — Ray

Solution: Hi Ray.  We can’t think of any logical explanation for the problem other than the possibility that your phone may be working harder to establish good connection to AT&T network compared to when it was still in its mother network (T-Mobile). Keep in mind that your phone is still running the T-Mobile firmware. This means that everything on it has been validated to work efficiently with T-Mobile system. Now that your still running a T-Mobile software but using the network settings of AT&T, some things must have changed, causing the device to spend more battery or processing power. We can’t be sure of this for sure but since you’re positive that the only change you’ve done is to use an AT&T SIM, this is the most likely explanation. Try to factory reset the device and see how it works. If that won’t solve your issue, you just have to accept the situation.

Below are the steps on how to factory reset your S7:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

Problem 5: Wet Galaxy S6 won’t power back on

Hello. So, my Galaxy S6 got wet. Not submerged. Just wet. My daughter splashed water on it from her bath (it was sitting on the bathroom floor) and I didn’t notice until about 10 minutes later. I took it out of the case and wiped the water off. It appeared to be fine. Then the touch screen stopped working. The phone is still on (at least until the batter dies) and because the touch screen isn’t working, I cannot turn it off. It doesn’t have a removable back either, so I don’t know how to go about taking it apart further to let it dry out. It is sitting in a bag of rice right now (dumb, I know, but what else can I do?) and before I put it in, the power button on the right side of the phone had also stopped working. What should I do? Can I take it somewhere? It is a Straight Talk phone. — Cailtinjmichael

Solution: Hi Cailtinjmichael. Unlike the Galaxy S7 and S8, your S6 does not have water resistance protection so even a splash can hurt it bad. Putting your phone in a bag of rice won’t do much at this time. Bring the phone to Samsung or an independent service center so the hardware can be checked. A professional also needs to check the hardware so it can be assessed if a repair will likely fix it or not.

Problem 6: Galaxy S7 won’t charge, won’t turn on

I have a Galaxy S7. Yesterday it froze and it won’t reboot at all. When I plug it into the wall, it shows a battery with a lightning bolt but it doesn’t fill up green showing it’s got charge. I have tried all the possible reboot fixes by holding in the power key and volume keys ETC but none of which have fixed the phones issue. I’ve looked all over the net but nothing seems to give me the right advice. — Kailadobson58

Solution: Hi Kailadobson58. The tips and possible solutions that you’ll find online are mostly intended to fix software causes of this problem. If your phone no longer boots up right now, that means that you can’t perform any of the suggested software tricks that you’ll find. It also means that bad hardware is the mostly cause of your problem.

Try to charge the phone with a different charger and USB cable and see if that will work. If you have a wireless charger, you can also try that to see if the problem lies in your phone’s charging port.

If you can’t power the phone back on using any of these means, have it repaired or replaced.

Problem 7: Accidentally dropped Galaxy S7 has cracked screen

I dropped my phone and there is a small superficial crack on the bottom by the home button. If I hit the power button, my screen goes black; it stays on. I can hear the pages opening or the volume buttons. Everything is responsive except the screen. it will blink and if I mess with it for a couple hours I can get it to light up. But I can’t let the display go dark or time out. Cuzco I’m screwed. — Jennifer

Solution: Hi Jennifer. If you want to fix the problem, you should stop looking for any software solution. There’s no amount of software tweak that can be done to fix a damaged hardware. Contact Samsung and have the device repaired or replaced. If your phone was part of your subscription plan, contact your carrier so it can be replaced.

Problem 8: Galaxy S7 apps keep crashing after installing Android Nougat

Hi. I recently updated my phone to Android version 7.0 and it is a nightmare. The most important issue is that I can’t view my messages or text on the system’s messaging app. When I tap to open… it immediately shows this message on my screen: “com.android.cts.ctsshim has stopped” or “com.android.cts.ctsshim keeps stopping”. Please help me what can I do to fix this problem? Many thanks, Sabrina P.s. if possible I’d like to avoid doing a factory reset. Thanks. — Sabrina

Solution: Hi Sabrina. The first possible solution to your problem is cache partition wipe. Do that and observe how your phone works for some time.

If the problem returns, make sure that all your apps are up-to-date and compatible with the current operating system. Even if the specific app you’re having problem with is okay, it’s possible that one of your apps is affecting the working ones. Go over your list of apps under Google Play Store app and make sure to check each one if it’s compatible with Nougat (Android 7.0). You can also observe how your phone works when it’s on safe mode. This will help you tell if one of the third party apps is to blame or not.

Below are the steps on how to restart your S7 to safe mode:

  1. Turn your Galaxy S7 off.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

If nothing changes even when your phone is safe mode, do a factory reset.

Problem 9: Galaxy S7 screen flashes green, screen won’t turn on right away after a restart

So, I have an S7. I began to notice something. Every now and then, when I turn off my screen, it would flash green, then turn off and when I try to turn it on again, it doesn’t turn on after I try for a few minutes.

Also, whenever I leave it in a cold environment, the same thing tends to happen. I tried asking somebody about it and they said it might be because I dropped it. I’m not sure if that is the case so that’s why I’m asking here before I pay for a repair. Hope you can reply, and thanks. — Cedric

Solution: Hi Cedric. Most issues about erratic or discoloration of the screen are caused by hardware malfunction. If you did dropped the phone badly before, that may have damaged something in the motherboard though it’s only now that you’re seeing the negative effect. Like water damage, the unnecessary shock from an accidental drop can lead to anything. For some, issues can begin showing right away, while in some cases, much later.

To check if hardware issue is to blame, do a factory reset first and observe the phone for a day. During this time, try to replicate the issue by doing the things that you normally do when this issue occurs. If the issue won’t occur, a software glitch may be to blame. That’s good news since you can most likely fix it by removing a problematic app, installing an update, or flashing.

If the problem continues even after a factory reset (and without apps installed), you must have a hardware issue at hand. In this case, you should consider repair or phone replacement.

Problem 10: How to change the appearance of Galaxy S7 after updating to Android Nougat

Hi guys. It’s not so much a glitch but everything seems dull and boring in the update. When I get emails, there is no colour to differentiate new emails from old ones and all the writing is the same size, nothing stands out. In the notification window the writing is like outlined as opposed to the writing being filled in like, it’s kinda ghost writing. It’s horrible. Can I change the text on everything? — Davedave1973

Solution: Hi Davedave1973. If you don’t like how the new update changed the previous look, there are a number of options that you can try.

Firstly, you can try to download a new font to replace the existing set of fonts. You can change the font, font style, and font size by going under Settings>Display>Screen zoom and font.

If changing the font won’t be enough, you can also try to change the look of some aspects of the phone by using a different theme. Just go under Settings>Wallpapers and themes.

Finally, you can also change the overall look of the phone by using third party launchers. Try to take a look at this link and visit a website that lists some of the popular Android launchers nowadays.

Galaxy S7 edge screen is damaged and keeps flickering, My Files app won’t open, other issues

Hello Android community! Welcome to our most recent #GalaxyS7 post for the day. We hope that the solutions we provide in this material will be useful for our community.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S7 stuck in recovery mode

I have a Galaxy S7 which I bought about 6-7 months ago. Now, a few days ago after the Android 7 update, it would not complete the update process and started to go into the recovery boot mode endlessly. Finally after a hard set (thanks to the instructions on your webpage) I was able to update the phone to Android 7. It worked OK for a few days but since I have downloaded some of the previous apps it has started to do the same thing.

This morning when I tried opening one of the apps, it froze and ever since then after I tried the simulated battery pull and it went into the constant ‘recovery booting..’ state. I removed the SIM card, (it does not have a the micro SD card), drained it of the battery as well. As soon as I connected it to the power source the ‘recovery booting…’ phrase has been coming and going after long intervals on the top left side of the screen. I cannot turn the phone off, so cannot turn it on in the safe mode; nor can I proceed with the hard reset because it will not get out of the ‘recovery booting…’ mode. Any recommendations? Thanks much. — Gurtej_cheema

Solution: Hi Gurtej_cheema. Try to wait for the battery to drain again, then try to see if you can do a master reset. In most boot loop cases, a factory or master reset fix problems so we hope the same will happen here.

You can also try to flash the bootloader and/or the firmware if the phone becomes stable enough. Below are the general steps on how to flash a bootloader. Exact steps for your phone model may be slightly different so make sure to find a good guide online on how to perform flashing on your phone.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

If the phone won’t become stable, or if you won’t be able to perform flashing at all, send the phone in for repair or replacement.

Problem 2: Galaxy S7 overheating and keeps rebooting on its own

I bought an S7 edge in Vietnam just over a month ago. It’s been working fine until last week when my phone has overheated and restarted itself. It then tells me I have to type in my password to access my phone. however it won’t show the keyboard app for me to type in my password and so I can’t access the phone. And it gets overheated and then restarts itself and this just keeps happening until the battery dies. All the other functions whilst the phone is locked works like emergency calls and the camera etc. However, it just won’t let me type in my password. It also gets really hot in this process too which is why I’m assuming it keeps restarting itself every minute. It also won’t let me reboot the phone only only restart it. — Hmh

Solution: Hi Hmh. Overheating and untimely restart usually go hand-in-hand because that’s a built-in mechanism of your phone to prevent hardware damage. An overheating phone is designed to shut down on its own if the internal temperature reaches a certain point to avoid damage to components. Overheating, in turn, may only be a symptom of something serious, though knowing it is beyond our ability to know right now. If this phone was dropped or got wet before, stop looking for ways to fix it yourself and simply send it in.

If you never dropped the phone or exposed it water or elements (too much heat or cold), try to wait until the battery runs out. Once that happens, let the phone cool off for at least 2 hours before charging it again. Once it’s fully charged, try to use it normally and see what happens. If possible, do a factory reset to eliminate the possibility of a software glitch. If your phone remains unstable after charging and the issue returns, there’s nothing much that you can do about it. Contact Samsung or your carrier so it can be repaired or replaced.

Problem 3: Galaxy S7 My Files app won’t open after an update

Hi there. I have a Samsung Galaxy S7. It recently asked me to install the software updates which i did. And a few things like font and icons changed. But since then i can’t open the “My Files” app. I tried putting it in Safe mode and it still wouldn’t open. I also deleted the cache and data. Something has happened since the software update. I can’t uninstall the app because it’s one of the set ones. Hope you can help! — Monica

Solution: Hi Monica. If you haven’t tried it yet, make sure that you also wipe the phone’s system cache. This procedure is a must-do if you encounter a problem after installing an update. Installation of updates and apps can sometimes mess up the system cache, which, in turn, can lead to all sorts of problems. To fix problems, you need to delete the existing system cache so the system will be forced to build a new one. Here’s how it’s done:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

If the problem continues after wiping the cache partition, make sure to wipe the phone via factory reset.

Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Problem 4: How to get out from Galaxy S7 Odin mode

Hi. My name is Maryann and I’m having trouble with my phone right now. First it got stuck on the Samsung logo for more than 10mins. Then i tried searching a way to fix it. i ended up following on Youtube by pressing Power, Home button and down volume. Then a message appear and pushed the up volume. now its downloading something which don’t allow me to turn it off. until now it’s still downloading. Please help because its scaring me that it might end up broken. I think it’s something about the software. Thanks. — Maryannmdaliva

Solution: Hi Maryannmdaliva. We don’t think the phone is actually downloading something. If you simply pressed Volume Up after booting to Odin mode, the device will be put in standby in preparation for a subsequent download. It doesn’t mean that it is trying to get some files from somewhere else though. You can reboot the phone back to normal mode by simply doing a soft reset. Here’s how to do that:

  1. Press and hold the Power and Volume Down buttons until the Maintenance Boot Mode screen appears (approx. 10 seconds).
  2. From the Maintenance Boot Mode screen, select Power down.
  3. Note Utilize the volume buttons to cycle through the available options and the Home button (located below the display) to select.

In some phones, pressing and holding both Power and Volume Down buttons won’t open Maintenance mode, but instead simply restarts it. The result should still be same though.

Problem 5: Galaxy S7 keyboard app keep crashing

When texting, my S7 freezes. The keyboard “dies” and does nothing. It’s “greyed” out so you can’t press the buttons, in the middle of typing a text. When it comes unfreezes, the letters, that I typed before it froze, physically come up and then eventually will start appearing as text. When this happens, all aspects of texting freeze or slow to turtle pace. I can’t find solutions for this issue anywhere on line. — Michelle

Solution: Hi Michelle. This type of issue can usually be fixed by deleting the keyboard app’s cache and data. If you haven’t tried that yet, here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, look for the keyboard app you’re using and tap it. Samsung keyboard is usually the default one but if you’re using a different app, be sure to tap the right one.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

You can do the same procedure on the messaging app you’re using, in case it’s also buggy.

Problem 6: Galaxy S7 edge screen is damaged and keeps flickering

I have a Samsung Galaxy S7 Edge. Recently did a software update, and quite soon after noticed that there was a line on the screen and a flickering. The flickering has got worse to the point that the led blinks green, and the back key lights up, but no image appears on the screen at anytime. Turning on or off doesn’t show up anything so can’t do a reboot. Please help my partner is due any day, and i can’t receive calls. — Afox

Solution: Hi Afox. Try to boot the phone to Recovery mode and see if the problem remains. Recovery mode does not need Android operating system in order to work so if an update caused a glitch, the screen should work fine and not flicker or show a line. In this case, you want to do a factory reset to fix the issue.

On the other hand, if the problem continues even when you’re in Recovery mode, that’s a sign that the issue is hardware-related. You must have the phone repaired or replaced.

Below are the steps on how to start the phone to Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Problem 7: Galaxy S7 screen damaged after phone was accidentally dropped

I’m sorry if I’m missing any details, however, I am scared out of my mind. My phone fell on to my rug last time and it would stay on. I then had to pay $200 to replace it. It is a Samsung Galaxy S7 regular not edge and I don’t have money to buy a new one. I really need it because I applied to a bunch of jobs and i use it on my everyday life and my mother won’t give $200 more to spend on a new phone since she still has to pay her hospital bills. I’m truly in a big mess.

So now for the details. i placed my phone without a case on my bed that is about 2 and a half feet above my bed. As i tried to stand up, it fell on my rug again. the screen then flashed white and it wouldn’t turn on for at least 3 min. I feared the worse then it did turn on and the bottom half of the screen kept sort of moving because it was glitching. I don’t know what to do. Can you tell me some things that might be wrong? without and a place that would replace it for free? i have Sprint and they charge $200 for a replacement. I truly need help. I don’t know what to do. — Fernan02

Solution: Hi Fernan02. As much as we would like to help, your issue is hardware-related and needs a hands-on repair from a professional. We understand it may be difficult for you to spend for repair but it’s the only way to fix the problem. The screen is clearly impacted and most probably permanently damaged so there’s no amount of software troubleshooting that you can do on your end to fix it.

We don’t provide hardware troubleshooting and diagnostics in our blog so if you want to do the repair yourself (which we strongly discourage), use Google to search for good guide. If you’re lucky and the damage is isolated to the screen assembly only, replacing it may work. Keep in mind though that you’ll still spend for the replacement component and tools to do the job. And that won’t even guarantee that your phone will work normally afterwards. If you want to take risks though, go ahead. iFixit website is a good place to start looking for a guide on how to replace the screen.

Problem 8: Galaxy S7 black screen with white “x”

So my S7 was completely fine then all of a sudden about a week ago I plugged it in to charge. The screen went black, a “x” popped up in the top right of the screen, the screen then acted like it rotated (the “x” moved to the bottom right), then an error somewhere along the lines of “cannot connect to gear VR. Please insure the device is properly inserted and try again” and then it won’t charge. I’ve tried 4 different chargers/cords (yes rapid charge as well) and it does the same thing. When it does this I need to restart my phone, plug it back in, and hope it charges or repeat. I’ve done a simulated soft reset and even that did nothing. — Suzie

Solution: Hi Suzie. This is an issue that usually results from a bad charging port. If you haven’t tried a factory reset yet, make sure that you do that first. We haven’t heard of an issue like this that was fixed by a factory reset but we still recommend that you perform it anyway so you can compare how the phone works after a reset and before a reset.

If a factory reset won’t change anything, hardware issue must be causing it. The black screen with a white “x” at the edge is usually an indication that the system “detects” that a VR (virtual reality) device is connected. We know you’re only connecting a regular charger so there clearly is a malfunction there. To fix the issue, some users were successful in it after cleaning the microUSB port. That’s probably because dirt or corrosion may have set in and altered the contacts somehow. If cleaning won’t fix your issue though, we recommend that you have the device repaired or replaced.

Problem 9: Galaxy S7 losing battery power fast

Hello! I would like to ask for your expert advice. I had a problem with the battery of my Samsung Galaxy S7 Edge. I had it replaced by the shop where I bought it. I just got it today. Now I noticed that the battery still gets low fast. We have few chargers of Samsung phones at home and I have no idea now which one is the right for my phone. Can you please give a tip on how to check the right cable for my phone? And if there is other way to make my new battery stay longer since it is new as I supposed. I have not charged it yet since the time I got it back. Looking forward for your kind reply. Thank you so much! — Kathleen

Solution: Hi Kathleen. We’re slightly confused. If you got your phone as brand new, it should come with an original Samsung charger that looks like this one. That makes us think that your phone may be not brand new, and hence did not come with a Samsung charger. If that’s the case, try to visit your local Samsung store and get an original charger from them. Or you can also visit their website and get one from them. An original Samsung charger should come with Samsung logo and should look exactly like the one in the link.

If you think your phone is draining battery faster than normal, it’s your job to identify what is the primary reason for it. Because you have a non-brand new phone, there’s a chance that the phone or the battery may be problematic for some reason. It may be the main reason why the previous owner sold it in the first place. To know if that’s the case is impossible though, unless a really good technician can run a thorough diagnostics.

Assuming however that the battery and phone in general are okay, the main reason for the fast battery drain problem may be your usage habits. Yes, how you use the device can impact battery performance. When it comes to this issue, smarts is necessary. How you use your phone can make or break the battery. For example, if you tend to maximize screen brightness all the time, you can’t really expect the battery to give you an entire day’s usage. The most is probably a few hours. A huge number of installed apps can also negatively impact the system and battery. If you have lots of apps running in the background, or if you tend to install apps with abandon, you may actually be installing something that helps drain the juice our of your battery faster. Remember, not all apps are created equal. Some may be optimized and regularly updated to help conserve battery power, while some may not. If you’re running Android Nougat, visit Settings>Device maintenance>Battery and check what app is eating up a huge chunk of battery power.

Discussing the entire possible causes for battery drain issue is beyond the scope of this article so we recommend that you do more research. There are other websites that can give you more tips and tricks on how to lessen battery drain in an electronic device.

Problem 10: Galaxy S7 edge sound notifications not working

So my Samsung Galaxy S7 edge phone’s notification sound isn’t working at all. I tried everything I could. I restarted it, changed notification sound and setting, the volume went into individual contacts to change each ones notification and i got no result. The Battery is not removable so I can’t do that. I want to know when I get a message this is very frustrating. Please help thanks so much. — Leslie

Solution: Hi Leslie. If you’re positive that you’ve already selected the right options under Settings>Nofitications, then the only remaining options for you are:

  1. cache partition wipe and
  2. factory reset.

Kindly refer to the steps above on how to do each of them.

Galaxy S7 won’t send SMS at random, keeps losing signal, “not registered on network” error, other issues

Hello everyone! Here’s the latest #GalaxyS7 article for you. This post addresses more S7 problems so please take your time to go over them. We will continue to publish similar posts in the future so keep watching for them.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S7 keeps rebooting on its own, settings keep changing

I have had no issues with my phone up until today. My alarm went off on it, then it instantly restarted. When it turned back on it changed the theme back to the default one. So I changed it back thinking the issue would be over. My phone then restarted 4 more times later in the day. Each time resetting the theme, and changing random settings on my phone like the performance mode and default messaging app. The last time it happened it zoomed the screen in on the home screen so some apps didn’t appear on the screen and the ones that did were a lot larger than usual, it randomly changed back but I forget what I did to make it change back. It also changed the default messaging app so I changed it back to the app I wanted. Now I don’t get notifications on the lock screen that I have a message even though the settings are set to show me notifications in the lock screen when I do. How can I get it to stop doing this, cause its been going on all day and its really starting to worry me? — Harris

Solution: Hi Harris. If you can’t remember what you did differently (such as installing a new app or update) that might led to this situation, we suggest that you do a factory reset and proceed from there. If the problem is being caused by an operating system glitch or app, it should go away after a factory reset. Make sure to observe the phone for 24 hours after performing a factory reset. Do not install anything during this time. Doing so will give you enough time to observe phone’s behavior.

Below are the steps on how to factory reset your phone:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S7.
  3. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  4. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  5. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  6. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  7. Once highlighted, you may press the Power key to select it.
  8. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  9. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  10. The phone will now reboot longer than usual.

If the symptoms you mention above will continue even after a factory reset, you can assume that the issue is due to bad hardware. Since there’s no direct way to know what specific hardware may be malfunctioning, your only option would be to have the phone replaced or repaired.

Problem 2: Galaxy S7 screen stays black and won’t turn on

Hello! I’m asking for your help on my husband’s behalf. He has a Samsung Galaxy S7 Edge. He was on his phone on Facebook, the battery was at 40% and connected to a battery pack charging and it suddenly went onto the Samsung Galaxy S7 Edge screen and frozen. He did a reboot pressing the volume up & power button together, it rebooted and then froze on the same screen. He tried a second time and it happened again. Third time it didn’t do anything at all. Black screen. We plugged it into the main charger just in case and no lights have come on to indicate it’s charging but when the battery pack is plugged into it the pack indicates a charge is being taken from it, the lights at the front show it. I tried rebooting it again, nothing. I tried going into safety mode, nothing. I read your troubleshooting article and tried almost everything but nothing worked (I didn’t try anything that would have resulted in going back to factory settings or resetting the phone entirely) please help if you can. — Holly

Solution: Hi Holly. To properly perform a soft reset, which is the equivalent of a “battery pull,” you are supposed to press and hold Volume Down and Power buttons (not Volume Up). If you’ve already tried this before attempting to contact us, the following are the other things that you must try:

  1. use another charger and USB cable
  2. try to restart the phone to alternate modes

Sometimes, a problem like this can be caused by a bad accessory so you want to ensure that the USB cable and charger you’re using right now are working 100%. Once you’ve made certain that it’s not the USB cable or charger, the only other thing that you can try is to see if your device can still power back on to other modes. Only then can you try to perform follow-up troubleshooting steps like:

  • wiping the cache partition,
  • factory reset via Recovery mode, or
  • flashing (via Odin mode)

Again, these items are only possible if the device will power on. If it remains unresponsive or dead, you must have it repaired or replaced.

Here are the steps on how to boot your S7 to alternate boot modes:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem 3: Galaxy S7 won’t send SMS at random

I’m not looking for a response, and don’t really want my message posted. Just FYI, in case it helps you. This is in regard to another user’s question: “I just purchase the new Galaxy S7 two days ago. I have noticed that a couple times a day, it will stop SENDING text messages. I restart the phone, and the issue resolves. I know this is a new phone, but I’m hoping that I can get some help with this. It’s annoying to do this 2-3 times a day. Thanks for your help.”

I’ve had this happen with, I think, all of my Galaxies (2, 4, 7) – It will just stop sending texts. Tries forever, then fails. Has happened to me numerous times in the past few days. In my experience… – Restarting the phone generally works, but often happens again a short time later – It happens while on both cellular and wifi, but sometimes seems to be triggered by going from wifi/no cellular to a cellular/no wifi area while trying to send the message – But the most consistent fix I’ve found is clearing up some storage (for me, photos) or deleting old text messages (PS, this page never completely loads, huge delays in response, worse the longer this message gets.) — JS

So, we apologize if we have to post it but we think it’s more helpful for Android community to see what you did to fix your issue.

Problem 4: Galaxy S7 turns on but remains stuck in Samsung logo screen

First I had red LED with black screen, then when I show it to Samsung care they somehow turned off red LED but the screen remains black and phone did not boot. They said that it’s a motherboard problem and asked for a heavy fees so I did not get it fixed there. I tried every possible solution on internet but nothing works. No buttons responded and mobile did not turn on. Then after several days, randomly I plugged in the charger and screen showed phone charging icons. So, in my excitement, I turned it on normally. It started to boot but as soon as it reaches Samsung logo then after some time screen went blank and now blue LED is glowing. so now again my phone is having black screen but now with blue LED light glowing and button is responding. Please help me. As I have important data in my phone. — Kumar

Solution: Hi Kumar. Try to see if you can turn the phone on to alternate boot modes (refer to the steps above). See if you can boot to Recovery mode first so you can try cache partition cache and factory reset.

If you can’t, try to see if you boot to Download/Odin mode so you can attempt flashing the bootloader and/or firmware. Below are the general steps on how to flash a bootloader. The exact steps may vary for your phone model so make sure that you do extra research on how to do it. The provided steps below are only for demonstration purposes.

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

If all these software solutions won’t work, or if your phone remains unresponsive at all, go ahead with motherboard replacement or repair.

Problem 5: Galaxy S7 screen is cracked and keep flickering, won’t turn on most of the time

This past weekend, I went to Mexico for a trip. My phone already has a cracked screen but still works perfect. I had my phone kinda like in between my legs and after we had crossed the border, my screen went black. Let’s say I wanna make a phone call. In order for me to do that, I would have to constantly turn my screen on and off again for about 5-10 mins straight before the screen finally appears and when it does, bottom quater of the screens flickers white. I turn brightness up all the way and flickering stops BUT if I lock the screen, another 10 mins of myself pushing the home and power button back and forth before screens turns on but flickers. Tried soft reboot and factory settings and nothing work — Jon

Solution: Hi Jon. Your phone is clearly having a hardware malfunction so we’re wondering why you haven’t tried having it repaired or replaced yet. For the benefit of everyone, the general rule in Android troubleshooting is simple, if factory reset won’t fix a problem, bad hardware must be to blame. You should resort to repair or replacement to resolve it. Don’t expect a software tweak will fix a bad screen, like the one you’re experiencing right now. If you’re lucky and the damage is isolated to the screen assembly only, repair should fix it easily.

Problem 6: Galaxy S7 messaging apps like Viber, Facebook Messenger, Whatsapp won’t work unless they are restarted

I have an S7 edge that i bought 2nd hand couple months old with receipt and all legit from seller. Phone is great however… my Viber, Facebook Messenger, Gmail accounts, Whatsapp…do not work unless i exit out and re-sign in. It’s so frustrating. I’m on my carrier Optus $2-a-day plan which is prepaid plan no longer available. When i went to Optus they seemed clueless and said its because my plan is 3G but edge is predominantly 4G bla bla…. What can i do because i now miss my crappy HTC one i used to have but it was basically on its last legs #sadface. — Livlualua

Solution: Hi Livlualua. Below are the things that you can try:

  1. Make sure that master sync is ON. This is done by turning on the Sync button in the status bar. Just pull the status bar on the screen and look for Sync button and make sure that it’s enabled.
  2. Delete affected apps’ cache and data. Depending on the cause, this troubleshooting step may or may not work. Refer to the steps below on how to do it for each app.
  3. Wipe the cache partition. The cache partition stores the a number of files but one of them is the system cache, which is a special set of files used by Android in loading apps. Sometimes, installation of apps and updates can corrupt the system cache, which, in turn, can also lead to all sorts of problems. Deleting the old system cache forces the phone to build a new one overtime so you don’t want to skip this step. It can be done safely without losing any user file like your photos, videos, etc.
  4. Factory reset. As the name suggests, this procedure will revert all software settings to their factory defaults. Most of the time, this procedure can effectively fix problems being caused by a software or app bug. If nothing will change however after doing it, you can bet bad hardware is to blame. If you don’t know how to do this, kindly refer to the complete steps above.

Below are the steps on how to delete an app’s cache and data:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

To wipe the cache partition, refer to the steps below:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Problem 7: Galaxy S7 keeps losing cellular signal, “not registered on network” error

Hello. I came across your very helpful website and wondered if you have any advice on this. I have an S7 Galaxy that I bought secondhand about 10 months ago. It is not locked to any operator.

About 10 days ago I started getting a “not registered on network” message, which meant I was unable to phone or send/receive messages. I have tried the following things:

  • Put the SIM card in another phone. It worked fine.
  • Soft reset
  • Restored my cellphone to factory settings.
  • Checked to make sure I have all the latest software updates.
  • Went into Settings>mobile networks … searched for available operators and tried connecting to them. I have done this multiple times. Sometimes, it works and I am briefly re-registered on the network, am able to call and send/receive messages. However, after a short time the problem reappears.

Sometimes I mysteriously get re-connected to the network without doing anything. Even when it shows I am registered on the network, sending messages is extremely slow and I sometimes have to re-try a couple of times before it goes through. I went into the local shop of my cellphone operator (I live in France, the operator is Bouygues). They say it is a problem with my cellphone, unrelated to their network. I’m thinking this might be a problem with the SIM card reader — perhaps a bad contact. Do you have any thoughts on this? Am trying to find a fix that would not require buying a new phone, since everything else on the phone seems to work fine. — Carol

Solution: Hi Carol. If SMS and other network-dependent activities work in another phone if you insert your SIM card to it, that’s a clear indicator that the problem is device-related. Do a factory reset and observe how SMS works without installing an app or update for 24 hours. If the problem continues to occur, get a new phone.

Galaxy S6 in-vehicle Bluetooth speaker not working properly after Nougat update, other issues

Hello Android community! Here’s another #GalaxyS6 article for you. As a continuation of our troubleshooting series for this device, we bring you more issues and solutions.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S6 screen flickers and freezes

My phone was working fine then suddenly its screen started to flicker in the morning a bit and by nightfall it was unusable. Screen flickers and hangs and when you turn the screen off and then on again brightness levels are lower than the settings. No auto brightness is on. When i continuously turn on and off the screen it starts working once the screen brightness comes to normal by itself. If i continue using one app for a longer period of time it starts on work smoothly but at one time i can use one app only now. Two apps and the screen becomes crazy. I did a hard reset. No change. Even reinstalled the software still the same. I am thinking about downgrading the software. Help me !!! — Ayesha

Solution: Hi Ayesha. Doing any further software troubleshooting won’t help. If by hard reset you mean factory reset, then downgrading the software version won’t make any difference at all. Factory reset should take care of any issue caused by a a software glitch. Since nothing changed after doing it before, we suggest that you hold off on doing any other software solution. A flickering screen issue is almost always caused by bad hardware so instead of wasting your time in flashing the firmware, just have the phone’s hardware checked by a professional.

Problem 2: Galaxy S6 touchscreen stopped working after it fell in water

Hi. I read your response to the person whose S6 edge fell in water and now the touch screen won’t work. You had suggested a hard reset in which you turn off the phone and then press all 3 buttons simultaneously. The problem with that is that it won’t turn off because the touch screen doesn’t work. If I push all 3 buttons while it is on, it will restart. When I did that, nothing changed–touchscreen still doesn’t work. What do you suggest will be the next step? I’m not sure which version it is. — Gduarte01

Solution: Hi Gduarte01. Exposing a Galaxy S6 to water is like a death sentence. It’s very rare to see a wet S6 survive without a scratch so if you haven’t done the basics like turn off the phone, open up the phone and dismantle parts, remove the battery, and dry the battery and the dismantled parts in a bag of rice for several days, we’re positive that that the reason why your phone’s touchscreen issue is due to a damaged screen assembly. If you’re lucky and water damage is isolated to the screen assembly only, the least that a technician may do is to replace it. That said, your next step is to have the phone checked by a technician so hardware damage can be assessed.

Keep in mind that moisture can stay inside the phone and do damage in the long run (that’s why water-damaged phone must be thoroughly dried). Repair or parts replacement may give your device a short life but eventually, it will still fail. Water, especially salt water, can lead to corrosion and corrosion can take some time to develop. If your phone will suddenly show problems weeks after repair, you’ll know your phone’s end is near.

Problem 3: Galaxy S6 won’t turn back on after it got water damage

Hi there. My daughter dropped my phone into the toilet. It was there for around 30 – 45 seconds. It was a clean toilet so only water there. I currently have it in rice, SIM card has been removed and the SIM tray also. Inside, i cannot see any white/red/pink. just silver/black. The phone was on as it went into the water, it came out not working, no lights/sounds etc. Any idea on what i can do? Thanks in advance. — Taragreeneyes

Solution: Hi Taragreeneyes. Unlike the Galaxy S7 and S8, your S6 does not have water resistance protection so it’s safe to assume there’s an on-going hardware issue preventing it from turning back on. Putting in inside a bag of rice won’t do much good at this point. You’re supposed to do that only after removing the battery from the system. Leaving the power source connected to a wet motherboard can short components, which can then lead to permanent hardware malfunction or failure. If you can’t open the phone yourself and do this critical “first aid,” we strongly suggest that you send the phone in or let a technician check it right away. It won’t guarantee that your phone will work normally again but at least you’ll get an objective assessment whether or not the device can be saved or not.

Problem 4: Galaxy S6 shuts down randomly, wifi won’t remain connected, weather app not updating after an update

I have a few issues with my phone and the cause could be related. They all started a couple months ago after a software update it seems.

  1. phone turns completely off randomly. sometimes it will stay on most of the day and most of the time it will shut off a number of times in just a few minutes.
  2. wifi….will not stay ON nor will it connect to a hot spot even at home unless I power down the phone and re-start.
  3. the weather app that came with the phone will not update itself. Its preset to update every hour but will not and it takes some fiddling with the screen to get it to update.

You asked for a version of phone I have but I am not sure what it is. I just entered what looked good to finish form….sorry thanks for any help you may offer. — Jim

Solution: Hi Jim. The first possible solution that you want to try is to wipe the cache partition. This will ensure that the system cache is not corrupted. System cache corruption sometimes happen after an update, leading to all sorts of trouble. Refreshing it though usually works. Here’s how it’s done:

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

If the problem persists after refreshing the system cache, you can then try factory reset. This will wipe everything on your phone and bring all software to its defaults. If there’s a glitch causing the problems above, factory reset should take care of them. Here’s how to do that:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S6 Edge.
  3. Press and hold the Volume Up, Home and Power keys together.
  4. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  5. Wait until the Android Recovery Screen appears after about 30 seconds.
  6. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  7. Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  8. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Problem 5: Galaxy S6 screen won’t work after it got wet

So I dropped my phone in my pedicure water at the nail salon. I immediately picked it up and dried it off. It didn’t get completely submerged. I think it was the top half that went in, not sure. Anyway, the phone will charge and turn on, but the screen won’t turn on. What I want to know is, is there anyway of getting my pics, contacts, etc off of it without the screen turning on? The buttons at the bottom light up white, it make the t-mobile chime when it powers on. the Light comes on when it’s charging. I just wanna know if there is any chance of getting my stuff off of it before I throw it out. Thanks! — Chris

Solution: Hi Chris. You’ll need a working screen in order to give permission for another device like a computer access to the internal storage device. Plugging it directly to a PC via USB, even if the computer can still detect the phone, won’t necessarily give it permission to browse the contents of your phone. That’s not how Android works. If you think the contents are worth a few hundred dollars, try having the screen replaced to see if it will work again.

Problem 6: Galaxy S6 in-vehicle Bluetooth speaker not working properly after Nougat update

Hi! So Nougat >:( (said in Jerry Seinfeld’s “Newman” voice). Ever since this update, my Bluetooth connects, but all callers hear their voice echoing back at themselves when I’m connected so it’s basically useless. I have to switch everyone off bluetooth and on to speaker phone so they don’t hear the echo. I’ve unpaired and removed the phone from the bluetooth in my car. I’ve done every reboot imaginable. I’ve reset the phone. Still, the problem continues. It’s SO frustrating! I can’t hear anyone through the speaker while I’m driving, and I can’t put them on bluetooth because they can’t hear themselves think when their voices echo back at themselves while they’re talking. Help!! — Bari

Solution: Hi Bari. An issue like this is common after an update. The surprising thing is, yes, it was the update on your phone that caused it, but it’s really not your phone’s, or Samsung’s, or Google’s fault at all. Smartphones receives more software updates than in-vehicle Bluetooth devices, which means that their Bluetooth system are more up-to-date. Now, when was the last time you ever updated your in-vehicle Bluetooth system? That’s where the problem usually lies. In almost all cases like yours, incompatibility issue occurs simply because of an older in-vehicle Bluetooth. At times, the profiles used by a Bluetooth device becomes incompatible with another device due to updates as well. If you’ve already tried doing a factory reset on your phone (to make sure that this is not an Android software issue), we suggest that you contact the maker of your car or the bluetooth device in it to see if there’s something that they can do.

Problem 7: Galaxy S6 stays black after battery replacement

I have a Galaxy S6. The screen went black and I had just paid to have the battery replaced. Well, 2 days after, the screen went black. I keep trying to hard reset and it will flash blue at the top bit isn’t showing anything on the screen. I am not sure if it’s the battery or if it’s the screen? I don’t know how the screen would be damaged because I haven’t dropped it. Maybe the screen connection is loose? Could you clarify if it’s likely the screen or the battery? — Cayla

Solution: Hi Cayla. It’s clearly not a battery issue. If it’s a battery failure, there wouldn’t be any LED light showing at all. To get to the bottom of the issue, you want to let a professional take a look at the hardware again.

Problem 8: Galaxy S6 edge plus keeps crashing, stuck in boot loop

Hi, I have a Samsung edge S6 plus and it keeps crashing, a blue light comes on and it gets stuck in a loop of the first Samsung black screen with model logo and then black Samsung loading page. and then it crashes again and it’s in this loop continually. eventually I don’t know how but it starts working again. This time however it wouldn’t restart. so I followed your page advice of holding down volume up, home key and power button but I can’t clear cache as my phone now has a blue screen with a robot with a refresh button in its tummy and white words at the bottom which say installing system update. I’ve plugged it back into the charger but I don’t know what to do now. Thank you and I guessed the android version, I’m not sure. Thanks again. — Amy

Solution: Hi Amy. If you’re trying to boot to Recovery mode and you’re doing it right, you should be in a different page than the one you’re seeing right now. We think you may be at Odin or Download mode, which is accessed with a slightly different button combination. Please refer to the steps below on how to boot your phone to each of these modes:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the Samsung Galaxy logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Remember, if your phone continues to reboot on its own, or won’t even restart normally, there must be a hardware issue causing it. You must have it repaired or replaced.

Problem 9: Galaxy S6 edge won’t charge via USB cable after an update

Hi. I have a Samsung S6 edge and over the last week or so I’ve had major charging issues. I updated the software after a notification. This is, I think, has been the start of my problems. I can charge the battery wirelessly, however 90% of the time when I charge via the cable it doesn’t recognize it, flashes up usb connected, gives the power sharing message or constantly flashes on or off charge. I’m guessing a software issue but I have done all the necessary shutdowns resets etc including factory reset. Does this mean my charger port/battery needs replacing? — Chris

Solution: Hi Chris. If your phone charges wirelessly without a problem, the problem is most likely found in the charging port. It may no longer be working properly and the system mistakenly detects the charger as another device. If a factory reset did not change anything, you should seriously consider sending the phone to be repaired or replaced.

Problem 10: Accidentally dropped Galaxy S6 Duos won’t read second SIM card, SIM card slot not working

I have a Samsung Galaxy S6 Duos that has work well for over 9 months. However, I recently dropped it (it has a protective cover) and the second SIM has not worked since. The SIM is OK since I can switch locations and it works fine in slot 1. I am presuming that either the contacts for sim slot 2, or the antenna (if they are separate), has been jogged or damaged somehow. In your opinion is this worth trying to get fixed (and how many shops have any experience of dual sim phones in the US) or should I simply get a new phone? — Paul

Solution: Hi Paul. The best person that can give you a more authoritative answer is the technician who has physical access to your phone. The hardware must be thoroughly tested first in order to know where the problem lies.

If you badly need the second SIM slot for your lifestyle though, we recommend that you simply get a phone replacement.  Unless an attending technician is 100% sure that he or she can fix the problem, there’s really no point in spending your money for an unguaranteed repair.

Galaxy S7 SD card not detected, keeps getting pop ups, other issues

Hi guys! Here’s our last #GalaxyS7 post for the week. We hope you’ll enjoy reading the issues and their respective solutions.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S7 purchased in the US not working in India

Hi All. I am having two problems. i hope if you guys can help me out.

1) I bought one Samsung Galaxy S7 edge phone and I have been told that this phone is factory unlocked worldwide. I bought it in the US and mailed it to India. When my brother inserted a SIM on it, no signal show up. Then I told him to reset, changes settings in Network but no luck. Then finally he reset it to factory unlock.

2) After factory reset still have same issue. No signal coming on phone but now when I restart my phone I am seeing Android logo on screen where as I should see SAMSUNG logo while starting up phone. Does this means my phone is not genuine as I am not seeing SAMSUNG logo or is there anything I have to do to change it. — Mukesh

Solution: Hi Mukesh. There are a couple of things to consider if you want to go to the bottom of the issue.

CDMA vs GSM. This is the first thing that you must consider when planning on using a phone to another network. CDMA (Code Division Multiple Access) and GSM (Global System for Mobiles) are two of the most common wireless technology that most carriers around the world are using. CDMA is not compatible with GSM and vice versa. Needless to say, the difference between them is usually the main reason why phones won’t work in another network. For example, in the US, Verizon phones usually won’t work at all, or may have some limitations when used in a GSM network like AT&T. Verizon uses CDMA while AT&T GSM. Because a CDMA phone is built differently than a GSM phone, even though they’re of the same model, you’ll still encounter incompatibility issues. The same can be true in your brother’s case. If the phone you gave him was CDMA and he’s on a GSM network, there’s no way that phone will work.

We know you were told the phone was unlocked but most of the time, it doesn’t work at all. Unlocking a phone only changes some software settings, particularly on the network function, but the hardware remains the same. A network unlocked CDMA phone may or may not work properly when used in a GSM network.

CDMA phones are more restricted than GSM phones. GSM phones store subscriber information in SIM cards so as long as it’s properly network unlocked, you can easily use another SIM card from another network and it should work. CDMA phones don’t work like that because subscriber’s information is coded deep within the software. CDMA phones may sport a SIM card slot but that doesn’t work like a GSM phone does. The SIM card is there to allow a CDMA phone to use 4G LTE, which is just a modified GSM technology. CDMA phones still need to dig deep into each software everytime a user want to make a call or send SMS. Needless to say, CDMA phones are usually locked to its original carrier.

Giving you more details about this topic is beyond the scope of this article so we recommend that you do your own research about it.

We know nothing about your brother’s phone but if you want to know if it’s a CDMA or GSM phone, simply do a quick Google search for its model number.

Different frequencies. Samsung build phones with a specific carrier in mind so it’s not uncommon to find a Galaxy phone model having many variations. For example, hardware specifications of Verizon is different from hardware specifications of AT&T phones. This means that even if both phones look the same outside, their hardware differ significantly inside. One of the significant differences can be the operating frequencies. Each carrier works in a certain radio frequency to avoid interference so each of their phones must be provided with compatible networking chip so they can operate properly. If the frequency of the phone is different from the frequency of your brother’s carrier, the phone can’t simply find the signal. Unfortunately, there’s nothing much that you can do about that since frequency capability is determined by the hardware installed. You cannot remove the networking chip from a phone and replace it with a different one. Again, we recommend that you do some research about this topic if you want to know the cause of the problem. Have your brother contact his carrier to ask for help regarding this matter.

Problem 2: Galaxy S7 not receiving SMS from iPhones and My Sprint app not working

Hi. I was recently at a Doctor’s appointment and logged onto their Wi-Fi. Since I returned home I cannot receive any texts from anyone with an iPhone. Also “My Sprint” is not working at all and my Google voice is not allowing texts to come through my normal messaging app.

All of my updates are complete and I tried to reboot my phone and also went into wifi and clicked on the Doctor’s office wifi and said to “forget” it but still nothing.

Please advise as I am literally having the day from hell between my phone an ld my druer being broken. Thank you. — Tlynalu

Solution: Hi Tlynalu. We can’t see any reason why SMS would stop working after using a different wifi network. Something must have changed in your phone’s networking settings to cause the problem. We’re not familiar with your phone, nor did you provide more information to help us identify the cause. We recommend that you contact your carrier for assistance.

Problem 3: Galaxy S7 stuck in Sprint logo screen after deleting files

I have the Samsung S7. Last night, I did a clean up of cache and old pictures. This evening i used my phone till it died. I charged it and turned it on upon 100%, however the screen locks at the Sprint flash logo screen. It stays on the screen and makes the battery hot. What is going on with my phone? Please help, i have tons of valuable pictures that i would hate to lose. — Rookie704

Solution: Hi Rookie704. We don’t think you only deleted cache and pictures. If you are 100% positive that all you did differently before noticing the issue was to delete some stuff, you must have deleted some critical files or folders that caused this problem. If your phone won’t restart normally now, you don’t have a lot of options.

Try to boot the phone to Recovery mode first and see if you can fix the problem by wiping the cache partition. If cache partition wipe won’t solve the issue, you should try a factory reset. That will delete your data of course but as we’ve said, you really have not much choice.

Here are the steps on how to start the phone to Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Problem 4: Galaxy S7 edge screen showing red and green dots after an update

On 14th June i downloaded the latest android version in my S7 edge and leave it to install over night. And when i wake up i start watching some videos, then i noticed there are some green and red dots on the screen. So i locked the device and reopened it. the dots are gone but after half a minutes the screen turns green and start flashing. At first i thought somehow i break the display or might some water in gone inside it though the mobile is water proof. i tried to restart it but i can’t because i can’t see any thing. But after some while it turn backs to normal but the dots and green screen still flashes from time to time jut for a blink. — Hamza

Solution: Hi Hamza. Try to wipe the cache partition first. If nothing changes, do a factory reset. Below are the steps on how to do each of them:

How to wipe S7 edge cache partition

Turn off your Samsung Galaxy S7.

Press and then hold the Home and Volume UP keys, then press and hold the Power key.

When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.

When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.

Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’

Once highlighted, you may press the Power key to select it.

Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.

Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.

The phone will now reboot longer than usual.

How to factory reset an S7 edge

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Problem 5: Galaxy S7 screen is black after water damage

My S7 edge which I bought a month ago fell in water. The screen blacked out and only blue light was showing. However I can feel and hear sounds coming from the device even though it’s black. I tried to reboot through various steps. at last I went to the place where I bought the phone. They opened it and found out that water has sipped in from SIM card sections and told me I have to change the screen but they don’t guarantee it will work. I’m confused, if i buy a new LCD screen will it work? Please assist. — Shanit

Solution: Hi Shanit. When it comes to water damage, no repair is guaranteed. There’s no way to know in advance if the current issue can be fixed by replacing a single component — the screen assembly. Water can damage other components in the motherboard and screen replacement may fix the black screen issue but the phone may work erratically in the near future, especially if there’s corrosion in the motherboard. The best thing that you can do is to let the device be checked by a good technician so you can get an honest assessment. If they’ll say that repair may not guarantee that the phone will work afterwards, you are better off getting a new phone. We know that option can be difficult but again, there’s no telling what components are damaged right now.

Problem 6: Galaxy S7 messaging app issue

I am using the message app that came with my Samsung Galaxy S7. I am having an issue with the message display screen that shows different people that I have texted. One time I can turn on my phone and the last message displayed will be what I sent to someone, but I have to select the person/conversation and open it to see their response. The next time it might show their response to a message two days ago, but not the message that I sent this morning without selecting the conversation and opening it. I would like it to always show the last communication in the response – whether it is me or the person that I am talking to. Any suggestions? I have rebooted it, but I can’t take the back off of this phone. — Tonnette

Solution: Hi Tonnette. We don’t think we understand what you’re trying to accomplish here but if you’re having trouble with one app, you can always try wiping its cache first, then its data later. Keep in mind though that clearing your messaging app’s data will erase your SMS conversations. If you don’t want to lose your SMS, try backing them up first using Samsung Smart Switch app.

Below are the steps on how to clear an app’s cache and data

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.

Problem 7: Galaxy S7 keeps saying SMS sending failed

My wife and I have S7s that just received the Android 7 update (hers a few days ago and mine a few hours ago). Since her update (and now mine) we both have the same experience with SMS/MMS messages. We get an error that the text failed, BUT it actually goes through! She did a factory reset last night and it did not correct the problem. We installed a new messaging app on her phone and it did not help. I reset the settings on my phone and no help. Any ideas? — Bigelot

Solution: Hi Bigelot. It can be an operating system-related issue. This means that the firmware update you installed (which was provided by or modified by your carrier) is poorly coded. Make sure to report the trouble to your carrier so they can look into it.

Problem 8: Galaxy S7 no notifications for MMS

My phone randomly stopped notifying me that I received group text messages. I went to investigate the problem and when I go to messaging settings>more settings>multimedia messages> turn on auto retrieve and roaming auto retrieve it then notifies me when I get a group text. BUT it notifies me as an individual message and I have to download each person’s response individually. It then adds the message to the group message. It’s extremely annoying and hope you can help me fix it. Thanks! — Courtney

Solution: Hi Courtney. Try wiping the messaging app’s cache and data first and see how it works. If nothing will change, do a factory reset. Refer to the steps above on how to do each of them.

Problem 9: Galaxy S7 SD card not detected, keeps getting pop ups

Hello. Yesterday my 32GB SD card disappeared and will not show in my file as being inserted even though it’s still in my phone. Today I took it out and put it in my Samsung tablet and it was not recognized as being inserted in there either. The only thing i have not did yet was put it in a card reader and insert it in a laptop. That’s my next move. My question is what did this? All i did was restart my phone because it said that i have not done so in a few days. I have done this a lot and I’m not 100% sure if the SD card was done before or did that but I’m pretty sure that it was. Im sick i have lost a lot of great music and no it was not backed up. At one point it was but someone stole my flash drive It was on. Is there any way to retrieve what’s on this SD card?

Also for about 2 months I keep getting a pop-up or something like that on my S7. It’s annoying. Is there a way I can get rid of it? When I went to the T-Mobile store they told me no. Hope to hear from you soon thanks. — Tamar

Solution: Hi Tamar. As we’ve always stressed in a lot of our articles, digital storage devices like SD cards are unreliable. They can die anytime without leaving a trace on what may have caused them to stop working all of a sudden. To discuss the entire gamut of possible causes on why an SD card dies is beyond the scope of this article but you can always Google it if you have the time. Knowing what caused your particular SD card to die is impossible so it’s best if you can leave it that way.

We want to give you some useful tips though on how to minimize this issue from happening again. Here are a couple of them:

  1. Avoid interrupting the system or device (by turning it off) when it’s trying to read from or save to the SD card. Some apps can be saved in an SD card and if you turn off your phone while an app is loading, it can corrupt the SD card. The same is true when the phone is trying to move files to and from the card.
  2. Unmount the SD card properly before physically removing it. You can do that by going under Settings>Device maintenance>Storage.

You can also visit our previously published post for more tips on this topic.

For the pop up issue, the answer really depends on what type of popups you’re getting. If they are ads or something that promotes a product or another app, your phone is probably infected with a virus so you would want to factory reset it first. After that, you want to make sure that you only install apps from trusted sources. Viruses in Android mostly come from bad apps so you only have yourself to blame if you don’t filter apps you install.

If you’re getting system notifications, you may be able to fix the problem by tweaking some of your settings. Next time you contact any support team, always provide as many details as possible. In this case, it would have helped us a lot if you included more details about the pop up, or provided more descriptions about it. You can’t expect us to help you if you give us anemic description of your problem.

Problem 1: Galaxy J7 flickering screen issue

Hi. My name is Atul Mishra. I use Samsung Galaxy J7. before few months my phone’s screen started flickering but days after that it stopped flickering automatically. It happened again continuously for one month then it stopped flickering again. I went to service center and they told me that it’s happening because of water. somehow my phone has absorbed moisture. They told me to change the motherboard but I did not go for it. few days after that it stopped flickering again. Sometimes I noticed that it is flickering because I install some apps like kik and 4Chat but after uninstalling that app it’s not stopping flickering. Sometimes it happens because of software update. Please fix my issue. Thanks. — Atul

Solution: Hi Atul. First off, the presence of water or moisture can result to permanent hardware damage. If your phone got wet or exposed to water before the flickering issue started, stop looking for solutions. You must either follow what the service center told you to replace the motherboard, or simply have a new phone. Moisture in the motherboard almost always lead to corrosion so you’ll still end up with a defective phone in the future.

Secondly, if you are 100% positive that your phone was never exposed to water before, the cause of the problem may still be bad hardware. To check if that’s the case, do a factory reset and let the phone run without any apps installed for a few days. If the flickering screen problem continues, that’s indicative of a hardware issue. You must send the phone in for repair or replacement.

If the flickering issue won’t occur after a factory reset and during the observation period of a few days, an app may be causing it. To identify the problematic app, make sure to install apps one be one so you can observe if the issue returns after every installation.

For reference, here are the steps on how to factory reset your J7:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  4. When the device logo screen displays, release only the Power key
  5. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  6. Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  7. Press Power button to select.
  8. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  9. Press Power button to select and start the master reset.
  10. When the master reset is complete, ‘Reboot system now’ is highlighted.
  11. Press the Power key to restart the device.

Problem 2: Galaxy J7 can’t make calls using an app when mobile data is enabled

Hello. I got your id from internet.  i am facing a problem with my new J7 mobile.

i am able to use internet by using data connection, but among all the software i am not able to use one calling application, which is itel dialer and not able to make call by using this.

On wifi connection there is no problem and on data connection it is not working.

the same app i installed on another 6 or 7 android mobiles and it is working very well on data connection.

i have updated my device software, but there is no use.

my back ground data restriction also disabled for this. Kindly advice. Regards. — Joseph

Solution: Hi Joseph. This is an app-specific question and it can only be checked by the developer. There may be a compatibility issue preventing the app from working in a J7 device. If you’ve already tried the usual app cache and data wipe troubleshooting, make sure to contact the developer of such app for support.

Below are the steps on how to wipe an app’s cache and data:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.

Problem 3: Galaxy J7 mobile data won’t turn off when SIM card is inserted

Hi! I just bought a Samsung Galaxy J7, and it is causing problem with its mobile data.

Just after I inserted the SIM, the mobile data automatically turns on but I can’t use it. And when i turn off the data from the settings the data icon in the notification panel doesn’t goes away, it stays. It shows ‘H’ symbol without any sending or receiving signals. I restarted it but, the symbol on the notification panel stays on, even though the option is turned off. Even on turning on it doesn’t work, I have data of about 100MB. Solution is appreciated. — Towhidur

Solution: Hi Towhidur. There may be an operating system glitch behind this issue so the first thing that we would like you to do is factory reset.

Sometimes, a corrupted system cache can lead to all sorts of problems so if you don’t want to do a factory reset right away, you can try to wipe the cache partition first. Here’s how:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Home key, then press and hold the Power key.
  3. When the device logo screen displays, release only the Power key
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. Press the Volume down key to highlight ‘yes’ and press the Power key to select.
  8. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

In case the issue is due to a third party app, you can also try to observe the phone while it’s running on safe mode. Like the cache partition wipe, you can do this before performing a factory reset. To do that, follow these steps:

  1. Turn the device off.
  2. Press and hold the Power key past the screen with the device name.
  3. When ‘SAMSUNG’ appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. Safe mode will display in the bottom left corner of the screen.
  7. Release the Volume down key when you see ‘Safe Mode’.

Safe mode blocks third party apps. If mobile data works normally with your SIM card inserted, that’s an indication that a third party app is causing it. Uninstall app until you’ve identified which of them is the culprit.

Problem 4: Galaxy J7 screen flickering at different brightness levels

Sir, i have Samsung Galaxy J7. my device has no problem but since some days the screen of my mobile start flickering. i don’t know why it happens.  I am very much worried about it. half of the screen starts blinking at low brightness. When i increase the brightness, the screen show no flickering but after few hours a slight flickering again started at that brightness level. kindly help me and guide me what to do. — Rabail khan

Solution: Hi Rabail khan. We’ve noticed a flickering issue on some Samsung devices before but they can be attributed to a bug in auto-brightness feature. Yours looks like a hardware issue though so the only troubleshooting step that we can suggest is factory reset (steps provided above). Once you’re performed a reset, let the phone run for 24 hours without apps so you can observe how the screen works. If the flickering problem remains, there may be an issue with the screen assembly. To fix that, you need to have the screen replaced.

Problem 5: Galaxy J7 hardware buttons stop working when the screen turns off

Phone type – Samsung Galaxy J7.

My phone’s power button, volume button and home buttons are not working. when I take out the battery and re- install it, the screen works and even keyboards are working. Then when screen light goes off it doesn’t works as none of the buttons are working. how to fix this?

Day before the phone went off i have connected my phone to car through bluetooth and played music almost for ten hours while i was travelling.but bluetooth is off now.please give me solution.is it a software problem or what? My phones software is upto date. — Kezang Jamtsho

Solution: Hi Kezang Jamtsho. Like Rabail above, you must do a factory reset first to know if it’s a software or hardware issue. Make sure that you observe the phone for a day after a factory reset (no apps installed). If you’ll get the same problem, you must have a hardware problem. You have the phone repaired or replaced.

Problem 6: Galaxy J7 flickering screen issue after repair

Good eve! I bought a Samsung Galaxy J7 last January 2015 and 1 month after i bought it, my phone screen is flickering when i turn off my screen light. So i decided to bring my phone to Samsung gadget care due to warranty. They fixed my phone and they told me that they changed the LCD. Last month, my phone keeps on flickering again. I already tried soft and hard reset but still same result. What would be the problem on my phone? They already change the LCD but still it keep on flickering.. Hope you could help me.. Thank you in advance…. God bless. — Rogelyn

Solution: Hi Rogelyn. Please refer to our suggestions for others who have similar issue. If nothing will change after you factory reset the device, bring it back to Samsung for another repair. LCD malfunction is rare and it is usually caused by damage from misuse — dropping a phone, exposing it to water, putting the device near a heat source, etc. We seldom hear of malfunctioning screen due to a software problem or bug so if your phone suffered any physical damage before, there may be a motherboard problem causing the screen to appear to flicker. If possible, ask Samsung to give you information about the repair and cause of the problem so you can prevent the issue from happening again.

Problem 7: Galaxy J7 takes a long time to type SMS for one contact

When texting only one contact it takes a very long time for everything to load. Sometimes i will even type a full message without anything coming on the screen. I can feel the vibration from pushing the buttons but nothing comes up. Sometimes it will put a few words on thw page other times it will back out completey. I dont understand why it only happens to one contact. — Jsmittle90

Solution: Hi Jsmittle90. Make sure that you wipe the cache and data (in this order) of all the apps involved when typing a message — messaging app, keyboard app, and Contacts app.

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.

If wiping the cache and data of said apps won’t fix the problem, do a factory reset.

Problem 8: Galaxy J7 wifi keeps dropping

When connected to WiFi it will drop the connection and I have to scan and connect again. multiple times. My husband has the same phone and his phone stays connected.

Also Google Play Store opens by itself and I have found no adware. I have had the phone for 6 days – problem from the start but my service provider says they find nothing wrong with it. — Nelmari

Solution: Hi Nelmari. First of all, it’s not normal for Android to open an app like Google Play Store by itself. There must be something causing it. It can be a bug or a malware.

Secondly, what you want to do right now is to ensure that you start from scratch so you can then observe if wifi works normally when there are no apps installed, and if the Play Store will pull itself up without any user intervention. Do a factory reset and see what happens. If the situation won’t change, have the phone replaced.

Your second issue may be due to a bug with the app itself so you want to make sure that Google Play Store app is updated after you factory reset the phone. Be sure to allow it to install updates automatically to keep the rest of your apps updated as well.

Problem 9: Galaxy J7 not receiving incoming calls

Hello. I have a brand new Galaxy J7 2016. I am not receiving incoming phone calls. I have taken the phone to the AT&T store, which wouldn’t touch it since it is an international unlocked phone. I called customer service which disconnected me and reconnected me to the network. I have taken out the SIM card, taken out the battery, did a soft reset, and updated the APN settings. Is there anything else I can do? Thank you for your time. —         Victoria

Solution: Hi Victoria. There a few things that you need to check to identify the cause of your problem. Since you never bothered to give us a history of what happened prior to noticing the problem, our suggestions may not be extensive.

Is the phone unable to receive incoming calls from one contact or multiple contacts? If you’re having a problem with a single contact only, make sure to check if you’ve accidentally blocked the number. If you’re not sure, simply delete the contact and add it again afterwards.

If you happen to have issue with multiple contacts or all callers, try to wipe the cache and data of your Phone app first (steps provided above).  Once you’ve done that, make sure that you delete all your contacts from the phone and re-add them. An efficient way to do that is by creating a backup of your contacts first using Samsung Smart Switch app.

Is call barring enabled on your account or device?

We don’t know much about your particular phone model so you have to contact your carrier to ensure that your account is permitted to receive a call. Since you’re on AT&T, which is a GSM network, try to insert your SIM card to another device and call it. If you’ll be able to call it on a second device but not on the first one, that means that there’s an issue with your J7. Try to factory reset it to restore all software settings back to defaults.

If, on the other hand, you will still be unable to call your number when your SIM card is inserted in another device, the issue must be account specific. Let AT&T know about it so they can check further, or simply replace your SIM card.

Problem 10: Galaxy J7 can’t send email over wifi

Hi. My Samsung J7 can receive emails with no problem at all. If i want to send emails i have to switch my wifi off and go to my mobile data. Surely, there is something not right. I have been to my vodacom shop several times and when they send emails it works but i figured out its because i am on mobile data. How can this be fixed? I am tired of paying every time they said it’s fixed. Thanks in advance. — Dorish

Solution: Hi Dorish. In most cases, an issue like this is due to authentication problem with an Internet service provider such as the one for your home wifi. ISPs don’t want that their SMTP server will be used for sending junk emails or spam when a device is outside their network. So, they require each and every device to authenticate properly before sending an email and this may be where your issue lies. If you did not enter the Outgoing Server Authentication properly during the setup, your email provider or Internet service provider (if they are one and the same) may be blocking your emails from leaving their network. We don’t usually encounter this problem with popular email services like Gmail, Outlook, Yahoo, etc so we’re assuming you have an email account provided by your carrier. If that’s the case, you must work with them to resolve this issue. Make sure that you ask them for the correct port number to use when setting up your email account. You may also need to use SSL in this case so be sure that you cover that too.

In order to manually enter server settings for your email account, you must choose Manual setup option. If you’re using the built-in Samsung email app, Manual setup option should be available at the bottom part after you’ve typed in your email address.

If you’ll  have the same experience after you’ve reconfigured your email account, continue working with your carrier for a solution.

Problem 11: Galaxy J7 can’t move apps to SD card

Hi Droidguy. I recently bought a Samsung microSDHC Card (memory card)/Class 10/HD compliant which was 32GB and I’m using Samsung Galaxy J7. My problem is the SD card keeps showing up not enough memory whenever I tried to move my apps into external storage. While in storage settings was 170MB used of 31.24GB. Every application that I successfully transferred to SD Card is missing. I had to redownload and reinstall again and again. Please help me solve my problem. Thank you. — Nurul

Solution: Hi Nurul. Not all apps can be moved to external storage. If you don’t find any option to move an app to SD card under Application manager, that means NO. it’s that simple.

However, if there’s an option to move an app to SD card under Application Manager but the phone gives you an error that there’s not enough memory in the card, there may be bug causing it. To fix that, make sure that you try another known, working SD card. If the problem remains, do a factory reset before attempting to move apps again. If the same thing happens on the second SD card, there may be an issue with your phone. In that case, you may be better off by replacing it.

Galaxy S8 camera vibrates when camera app is used, music player skips tracks, other issues

Hi Android community. We bring you one more post that answer some questions regarding Samsung’s newest high-end phone, the #GalaxyS8. We hope you’ll find this material useful.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: How to block private numbers on Galaxy S8

I get a lot of blocked calls so I downloaded an app. It was working fine then one day I was on my phone and the private call called in while I’m on the phone and the whole call dropped. So I thought it was the app so I uninstalled and downloaded another app that blocks private numbers and it’s still doing the same thing, dropping the call that I’m on. I want to block private numbers without having the calls I want dropped. — Tara

Solution: Hi Tara. First of all, installing a third party app (we’re assuming the apps you installed are not from Samsung, Google, or your carrier) to block calls is redundant since the default Phone app from Samsung already has such feature. We don’t know what app you installed though so we cannot say for sure if it works properly or not. Try to avoid installing anything unless the feature you’re looking for is totally absent from your system. This will not only free up memory space but can also spare you from additional burden on the battery, as well as prevent you from unnecessarily exposing your information from third parties. If you want to use the built-in call blocking feature in your Phone app, do the following:

  1. Open the Samsung Phone
  2. Open Settings by tapping on the three-dot icon on the upper right.
  3. Tap Settings.
  4. Tap Block numbers.
  5. Tap Block anonymous calls. This will tell the phone not to receive calls from unsaved numbers.

Secondly, the calls dropping problem may be fixed by your carrier so we recommend that you ask them for support on this one. They are in the best position to address this issue since they are in the business of providing calling service to you in the first place.

Lastly, again, we recommend that you refrain from using third party apps for this issue. Unless you are 100% positive that such app can help and the developer’s reputation is okay, you should just stick to the first two suggestions above.

Problem 2: Unable to send videos in Total Wireless Galaxy S8

Hi. We purchased our S8s new from Walmart in March 2017. We have Total Wireless service (Walmart based) on Verizon Carrier. I have been trying to send small videos through text messages app and it will not go through. We also used to be able to attach at least 2 pics at a time and send, but now it’s only one. It says that data limit reached when we do either. I’m quite frustrated because according to Verizon we should be able to send up to 100 MB messages. 1 video message is 55.6 MB for example. These are not that big.  Was hoping you might have a solution. — Dana

Solution: Hi Dana. This is a problem that should be fixed by your carrier, Total Wireless. Verizon is simply providing the physical infrastructure but the system, that is, software and under-the-hood workings, are provided by Total Wireless, which is your carrier. You should talk to Total Wireless about the issue and not Verizon. There may be a certain file size limit when it comes to sending MMS on their system and you may be going over that limit.

Total Wireless is a prepaid wireless phone service so if you run out of mobile data credits, MMS, which requires internet connection to operate, will obviously fail. Make sure that you troubleshoot the issue when you have working mobile data connection.

Problem 3: Galaxy S8 camera vibrates when camera app is used, music player skips tracks on its own

Hi. I have two main problems with my phone right now.

The first is with the back camera. Whenever I turn the camera on, the camera starts to vibrate for at least 10 seconds before it stabilizes. It is only after that vibration that I can use the camera. While it is vibrating the image is blurry and it makes a funny vibration sound close to the sound bee will make and of course no other button nor camera option works while it does that.

The second is with the inbuilt music player. That is the only music player I use in my phone and recently music stops playing on its own and sometimes it skips to the next music still on its own. I can’t listen to music anymore due to that. Then again I have noticed it does that when my earphones are plugged in. I might be wrong but so far I have not encountered the issue when I play music on my phone on its speakers.

Apart from that another problem I have encountered and also noticed it only when my earphones are plugged in is the fact that the Google voice mike opens on it’s own. It also did that with S voice, as in it will open on its own and I thought deleting the S voice app will solve the problem but instead it made it worse. I really do not know what else to do. Please help me out. — Gaelle

Solution: Hi Gaelle. We have no idea about the history of your phone, if whether or not it suffered any physical damage due to moisture, temperature extreme exposure, or water damage, but we suggest that you don’t address the issues individually. Instead, we recommend that you treat these issues as symptoms of a rather bigger issue, probably a hardware one. A new Samsung flagship like an S8 shouldn’t have these issues so early in its life so something’s not really right hardware-wise. For example, the camera vibration that occurred when you open the camera app should not be there in the first place. To check if it’s a hardware issue, make sure that you do a factory reset and see what happens from there. If the same symptoms continue to occur after that, with no apps installed yet, you can bet bad hardware is to blame. In that case, we strongly suggest that you contact Samsung or your carrier to have it replaced.

For reference, here are the steps on how to factor reset your S8:

  1. Back up data on the internal memory. If you have signed into a Google account on the device, you have activated Anti-theft and will need your Google credentials to finish the Master reset.
  2. Turn off the device.
  3. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  4. When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
  5. Press the Volume down key several times to highlight “wipe data / factory reset.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, “Reboot system now” is highlighted.
  10. Press the Power key to restart the device.

Problem 4: Galaxy S8 screen remains black and won’t turn on

When the phone is powered on, the light at the top flashes showing it is powered on but the screen is black. I cannot also using quick shortcuts bring up the camera which shows on the screen and one-handed mode which shows the normal display in the background with a smaller version of the black screen in the corner. I have tried when it is powered off accessing the recovery mode. before I get there it has 2 screens one saying installing update and then the next saying no command. I have got into recovery mode and cleared the cache but that has not fixed the issue. i have also held volume down key, home key and the power key.and it says do you want to download the custom OS. i have tried clicking the volume down key to cancel but every time I do it the install custom OS screen appears. I don’t know if this is relevant or not but i figured it was better to include it than not.

The screen also overrides the black screen when a phone call comes through. It started last night when my phone was on 2% while I was using an app. So i quickly went to plug it in. The screen went black and the blue light came on to indicate that it was powering off. Then it quickly flashed up the home screen, then shut down again. After leaving it to charge a while i turned it on and the black screen started. — Ewan

Solution: Hi Ewan. We’re not sure if we understand the situation clearly here but there’s only one overriding rule that you should follow. If the phone appears on (because it makes sound notifications and vibrations) but the screen remains black regardless of what you do, something must not be right with the screen assembly. It’s either physically damaged, or there’s an unknown hardware glitch preventing it from turning on. Either case, you must let a professional take a look at the hardware to fix the problem. There are no software tricks that you can do in this situation.

Problem 5: Galaxy S8 won’t show app shortcut in Home screen

Anytime that I download a new app from Google Play app, after it downloaded and it tells me it has added the app to my home screen it isn’t there. When I pull up the screen with all the apps it isn’t there either. I search for it and I find it and then from there I press and hold until I see add to home screen and I click that and it doesn’t go to the home screen. Any apps I’ve had in there for awhile it add to the home screen just find. This is super annoying when I wanna get to the app quick. — Cmjimenez87

Solution: Hi Cmjimenez87. In order to assist you, we need more information further. What you provide are very basic and do not give any specific details that might help us figure out the cause. Please get back to us and provide relevant details by answering the following questions:

  • What is the name of the app are you having a problem with?
  • Are you using stock Samsung firmware or custom ROM?
  • Did you install any other apps that might modify home screen behaviors, or prevent an app shortcut to be added to the home screen?
  • Did you do anything different prior to noticing the problem like install an app or update?

Once you get back to us, we’ll update this post accordingly and provide the answers.

In the meantime, you can also try to do a factory reset and see if that will make any difference. Refer to the steps above on how to do it.

Problem 6: Galaxy S8 videos sent via MMS are grain, low quality

I have the brand new Galaxy S8. For work, I often have to send videos to my boss through text. Even one 15 second video on the lowest possible quality setting is so grainy, you can hardly make it out. This is a brand new, 2017 phone. I really hated Apple and was really looking forward to switching to Android, but even my old iPhone 4 from years ago, sends clear video with ease. I know this issue was discussed, but it only explains why it happens, not how to solve the problem. I can’t imagine that such a huge company boasting such an awesome camera and video update has a problem like this that can’t be fixed. — Rebekah

Solution: Hi Rebekah. The problem is not your phone but how the messaging app or your carrier’s system converts (which one is responsible must be figured out by your carrier) reduces the quality of your videos. Pictures and videos sent as MMS (via text) are often converted by carriers to save on bandwidth, or to allow them to be transmitted in the first place. Stop blaming Samsung and start talking to your carrier about it.

Problem 7: Company app won’t work in Galaxy S8

Yes, thank you. I have problems getting into a company app. Worked fine for 3 weeks, then won’t get on to app. It works fine at home but not at work. I have took it to BestBuy twice and talked to IT at work. They say it is the phone. I had another device sent to me. This one worked for 1 day and does the same thing. Can you give me any advise? Thanks. I have cleared all cooking and browser history. — Robert

Solution: Hi Robert. First of all, we don’t know what app you’re talking about and we have no idea what error or problem you’re having. Let the developer, the maker, of the app know of the issue so they can check what it’s not working on your S8. there’s a chance that they haven’t coded it to work with your phone since it’s the latest from Samsung.

Secondly, even if we do know its name, we will still be unable to help you since we are not the developer of such app. It may be incompatible with your phone, or something must have changed to cause it to fail. Did you install any update before noticing the problem? If you did, try to uninstall the update (we’re assuming it’s an app update) by simply deleting the app’s data. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Cache and Clear Data buttons for the application.

Problem 8: Galaxy S8 screen is black, won’t power back on

I had to write to you from my GF’s phone because my phone won’t turn on at all. I have a Galaxy S8 plus. Yesterday, throughout the night when i connect it to the charger it will turn off on its own. Phone hasn’t been dropped nor has the battery ever been drained. A few times it would turn back on. But since 1am, it doesn’t turn on at all. I’ve tried holding the volume up button and power button and nothing. Any advice? Or should i just go to the store? Thanks. — Osmany

Solution: Hi Osmany. Try to see if you’ll be able to turn the phone on to other modes — Recovery Mode, Download Mode, or Safe Mode. If it can power on to any of these modes, there’s a chance that you’ll be able to fix it on your end by doing follow up troubleshooting. Below are the steps on how to boot to each of these modes and the respective troubleshooting that you can do afterwards. Remember, if your phone won’t power on at all, or the screen remains black, have it replaced.

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the Samsung Galaxy logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem 9: Galaxy S8 not getting signal

My Samsung Galaxy S8 gets no reception at my lake cabin. I have a Tracfone service now and have gotten service there in past years with my Tracfone flip phone, but not with my Galaxy S8. I couldn’t get service there with T-Mobile either on the Galaxy S8. I think it’s the phone and not the service. Can you help me? I can’t answer your questions. — Kathy

Solution: Hi Kathy. We don’t think there’s anything that we can do to help you in this case. You should talk to your carrier and see if your cabin’s location is covered by their service. You can’t just rely on historical experience. It’s possible that the area may have very poor to non-existent coverage, or there’s an on-going outage that affects your location. Your carrier should be able to confirm which of these scenarios is true. There’s nothing a third support team like us can do to improve the signal in your area.

Problem 10: Galaxy S8 screen showing pixelation, keeps flashing

First problem occurred 2 days after I purchased the phone. a number of pixels broke in the upper corner, when I returned to best buy to see what could be done, was told might or might not be a defect, nothing they could do. I would have to pay to get it repaired.

Second, the screen will flash when open or flashes open and closed. — William

Solution: Hi William. The two issues might be related and has one single cause. To check if it’s a screen problem, do a factory reset and observe what happens. If the problems continue, boot the device to, say, Download Mode (steps provided above). Download mode runs a different code and is separate from the operating system so if the problem is Android specific, the screen should work fine, there shouldn’t be any pixelation and abnormal flashing.

If the issues remain even when you have the phone in Download mode, that’s a clear indicator that the screen is defective. You should have the screen or the phone replaced. No software “magic” exists to fix a bad hardware.

Problem #1: Galaxy S5 screen flickering when it’s about to sleep

Hi, I have just recently encountered a few problems with my phones screen. It started about a week ago and it is really beginning to worry me. Really hope you could help me out on this. Listed the problems below.

When locking the phone, the bottom of the screen will have a few bars of horizontal green lines flickering. When the phone is about to sleep due to inactivity, the whole screen will have bars of horizontal green lines flickering. Sometimes on the screen, there will be an obvious difference between the top half and bottom half of the screen. The top half will be brighter and the bottom half is slightly darker and there will be an obvious line diving the two. Really worried about this and would appreciate your advice on this. Thank you! — Samantha

Solution: Hi Samantha. There’s no known software glitch that can cause the problem you describe here so it must only be a bad screen. If you dropped the phone before or exposed it to water, this might be the result of any of them. If you want to confirm that it’s not a software problem, consider wiping the phone clean by doing a factory reset. If nothing changes immediately after performing the reset, that’s proof enough that bad screen is to blame. To fix it, you must have the screen replaced.

For reference, here are the steps on how to do a factory reset:

  1. Turn off your Samsung Galaxy S5.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.
  5. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  6. Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  7. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

NOTE: Factory reset will erase everything stored in the phone’s internal storage device. Make sure that you create a backup of your files before doing it.

Problem #2: Galaxy S5 turns on but won’t boot past start screen

My husband’s Samsung Galaxy S5 froze while he was on Facebook and then turned off. It would not turn back on. The battery itself is good but it can’t be charged either while it is in his phone. I charged it with my phone. I still could not turn it on but I was able to start it up with power, home and volume up button. I cleared the cache partition and do a factory reset. Then I tried to reboot the system and nothing is happening. Only a short vibrate every couple of seconds (reminded me of a heartbeat :)).

I even tried to start it in safe mode but with the same results.

Also, my husband said that Facebook did an update about an hour or so before it died. Could the update have corrupted the phones software? Thank you for your advice upfront. — Mpbair

Solution: Hi Mpbair. We don’t think an update for Facebook app can cause this kind of problem. There must be another reason why the phone no longer boots up normally. If you can boot it to Odin or Download mode, we recommend that you try to flash its bootloader first to see a difference. For this procedure, you need to have a computer so you can install Odin app to it. Odin is a special software tool needed to install updates or an operating system to a Samsung device. If you haven’t heard of Odin or flashing before, make sure that you do some reading about them before attempting to modify your phone’s software. XDA Forums is a good place to start.

Flashing is a risky procedure and can cause temporary or permanent damage to your phone’s software environment.

We don’t usually recommend modifying official software but since there’s nothing much that you can do in this case, we will say go ahead.

Once you’re confident that you can do the flashing procedure, start downloading the necessary or compatible Odin version for your phone in your computer. You also need to have the latest Samsung drivers for mobile phones installed so try to look that up as well.

Then, when the tool is ready, head over to Sammobile site and look for the correct firmware for your phone. Here’s the rest of things that you then need to do:

  1. Look for the correct firmware for your phone model and download it. Make sure that select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

If flashing the bootloader won’t work, consider flashing the firmware you have instead as that may fix the problem as well. The steps should be similar to the ones above so, again, do some research before you commit to doing it.

Problem #3: Galaxy S5 keeps crashing, apps won’t load

Hi. I’m hoping you can help me. I have had a lot of problems with my phone lately. I am on my second one as the first one died. The battery performance was just so bad I could no longer use it.

The second one has also had issues. I have had to do a factory reset on several occasions. It has turned itself off when I have been using an application and then when it turned back on I had messages saying google.com.apps etc etc and the phone would not work.

After the latest factory reset it now says package installer has stopped working. It won’t run a lot of the apps on my phone e.g. camera as well as some that I have installed myself. I have tried further factory resets but this one seemingly won’t go away. Is there anything I can do to sort this out?

Thanks in anticipation. — Paul

Solution: Hi Paul. If several factory reset instances did not improve the situation at all, there must be a hardware issue behind the trouble. Factory reset forces the phone to return all software settings to their defaults, effectively removing any glitch or bugs that may had been introduced in the course of usage since unboxing or the last factory reset. If your phone behaves exactly the same after a factory reset, that means that the procedure does not address the problem at all.

Although we’re quite confident that there’s a hardware problem causing your trouble,  you can do one more software troubleshooting to see if it will make a difference. The procedure is called flashing and requires a computer to do it. Providing the exact steps is beyond the scope of this article so you must do some research to get a good guide somewhere. A good flashing guide should give you all the steps you need to do as well as links where to download Odin software and firmware from. A popular repository of Samsung firmware is a site called Sammobile. Make sure that you get the correct firmware for your specific phone model. Using an incorrect firmware version can cause complications.

Remember, if flashing stock firmware won’t solve your problem, send the phone in.

Problem #4: Galaxy S5 slow performance issue, apps are slow to load

Hi. I own a Galaxy S5 which I have had for about two and a half years. In the last month or so it has started acting up. The first issue was that the battery was draining really quickly so I bought a new battery… but the problem continued. So I bought a portable power pack so that I could charge it on the go.

But since then other problems have developed… mostly the biggest problem is that it seems to temporarily freeze when I’m trying to do anything. For example, If I’m typing a text, I’ll type a letter and nothing seems to happen. So I’ll type it again and then suddenly both letters appear. Also I have this lag when I’m trying to close and open screens… It’s driving me crazy!

I went through and closed all apps as it was suggested to me that this might be slowing my phone down. I also tried turning off wifi, location and bluetooth, although it worked fine with all these things open prior to recently. Anyway this didn’t fix the problem. I also tried shutting down and restarting.

I would be very appreciative of any help you could suggest.

Thank You. — Sue

Solution: Hi Sue. Older phones tend to get slower as they age. That’s a fact.  As you use your phone day in and day out, the storage device gets cluttered, which can then lead to noticeable delay when doing even mundane tasks. If you are absolutely sure that your phone was never physically damaged (accidentally dropped or exposed to moisture or heat), you may be able to remedy the situation by wiping the cache partition and doing a factory reset.

Wiping the cache partition is helpful in dealing with general performance issues. If you’ve noticed that apps tend to load slower or keep crashing at random, doing this procedure may easily fix the issue. Here’s how it’s done:

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

The steps on how to do a factory reset is provided above. Make sure that you back your files up before proceeding.

If these two procedures won’t make a difference, you can assume that the general system slowdown is due to aging hardware. Unfortunately, there’s not much that you can do about it. If you want to save yourself from trouble, consider a phone replacement.

Problem #5: Galaxy S5 won’t turn back on after watching a movie

I have the Galaxy S5 and a couple months ago, my phone completely died while watching a movie. It was fine because I already had another phone I could use, but I recently realized that I needed to get some pictures from my last vacation off of my phone. It won’t turn on whatsoever and since it died, I haven’t seen the screen turn back on. However, when I plug it in, I can feel it heating up. I have tried all of the methods shown on here other than completely disassembling the phone. That includes holding down the power button with the battery out and holding down the volume up button, home button, and power button. I haven’t seen the screen light up the entire time I’ve been trying to fix the phone and the notification light has also not come on. Is my phone dead forever? Will I ever be able to get my photos off?

Also, I have seen people fixing their phones by hitting them on tables. Do you know if that works? Thank you and I hope you can get back to me soon! — Steph

Solution: Hi Steph. The answer to your question whether or not the phone is permanently bricked depends on where the problem lies. If the cause of the issue is a bad battery for example, a simple battery replacement should fix it. However, if the real reason why it won’t turn back on at all is located somewhere in the logic board, like a damaged power IC, a repair may or may not fix it. A damaged logic board part can be replaced by a good technician but that’s only possible if it can be identified first. Most of the time, identifying the malfunctioning component can be tricky so there’s a good chance that even a highly trained specialist may not be able to do it. Because there’s no way to access files in the phone’s storage device unless the system turns back on, the main issue that you want to address first is on how to power the phone back on. If you can’t do that, those files are gone forever.

Unnecessary shock is one of the surest ways to kill an electronic device. If you want to ensure that your S5 is dead, go ahead and do it. So, no. Hitting your phone on a table goes against the logic of taking care of an electronic device.

Problem #6: Galaxy S5 won’t charge, won’t power back on

Hi. So my phone has power drain problems and charging problems as a result (i am on the 3rd battery so it’s not that). So to get past the charging problem i turn it off over night so it will charge completely for the next day. But yesterday when i turned it off to charge it I plugged in the charging cable but the charging mode never activated. And then i tried turning it on but it wouldn’t. I then removed and put the battery back in which, didn’t help. I then tried holding power+volume up+home but this also did nothing. i decided to leave it plugged in to charge and woke up with it charging finally.

But today it has done the same thing when I’ve turned it off and I tried plugging it into my laptop which didn’t detect my phone. Do you have any possible fixes or ideas about what’s causing it?

I also haven’t dropped it, spilt anything on it, over heated it or anything harmful to it. Thank you. — Cindy

Solution: Hi Cindy. Try doing a closer inspection of the charging port to see if there’s a damaged pin or lint inside that may prevent good contact with the charger. If possible, try using a form of magnification and bright lighting to clearly do this ocular inspection.

If everything appears in place, try using another USB cable and Samsung charger. There may be an issue with the current charger or cable you’re using.

If using another charger and cable won’t fix the problem either, using another S5 battery may. If you have another S5, try to see if you can turn the phone on using a different battery. If you don’t have another S5, a friend may have one so try that too. If either of these two is not possible, bring the phone to a service center so they can try an S5 battery on it. If possible, go to a Samsung service center so if the problem won’t be fixed by using a new battery, you can just have the device repaired.

Problem #7: Galaxy S5 losing storage space fast after installing Android Marshmallow

Hi. My Samsung Galaxy S5 (recently updated to 6.0.1) is experiencing a weird problem and I was hoping you might be able to help. It was getting stuck on the loading screen (with the pulsating word SAMSUNG) and was very hot right after installing 6.0.01. So, I took the battery out and left it out over night to cool off and try again in the morning. It restarted fine in the morning, but then I got a number of errors about running out of disk space. I tried deleting apps, moving stuff to the SD card, removing the SD card, but still ran out of memory. Apps started crashing, and then the phone rebooted. It got stuck on the loading screen like before, and started getting hot, so I turned it off and charged it. When I booted it back up again, I saw the memory was completely full and I wasn’t able to remove anything without the applications crashing. So I did a factory reset and then booted it back up, hoping my problems were solved. I checked the storage usage and saw I had about 8 GB free. When I check back a few minutes later, it was down to 7 GB, and it continued to drop at about 0.01 GB every few seconds I checked. Eventually it hit 0 free and everything crashed again. I factory reset it again, without my SD card in it, and watched it without doing anything except doing the basic setup and it still continued to drop in space. Any suggestions?         — Robert

Solution: Hi Robert. We assume that you received the Marshmallow update via OTA (over-the-air) since you did not indicate anything that might suggest otherwise. In that case, you should let your carrier know about the problem so they can advise you if other users have reported the same situation. It’s actually our first time to encounter this type of update issue so there’s a chance that the problem may be caused by inefficient or poor coding. Letting your carrier know about the problem may not give you immediate solution but it should prompt them to let their developer team to look into the issue.

If you updated your phone manually via Odin, we suggest that you flash the previous firmware and avoid installing the current firmware again.
