Problem #1: Galaxy S7 stops booting normally after installing Android Nougat

I downloaded the latest update (Nougat) over night. In the morning, I let it do its thing. Went through the update screen (green with the gears) and about 20 minutes later it was done. It rebooted and basically have been stuck on this loop of phone turns on, “Android System Upgrading Android..” with the bar stuck at about the “a” in upgrading. Couple of minutes goes by, phone restarts, I’ll see the lock with the blue and green lines that make a circle, it comes back on. Later. Rise. Repeat.

Sometimes when it’s on, i’ll try and go to settings or another app and it’ll go to a screen like it’s loading and nothing comes up. Just a white screen. I have no clue what to do next. I can’t save off anything on my phone because it restarts or wont even let me open an app. Not even sure if the phone connects to the internet/wifi in case it needs to download more info. Thanks in advance for any help. — PT

Solution: Hi PT. Although most update installations proceed as normal, some users may encounter problems. Such problems are caused by a wide variety of possible causes. We don’t want to discuss the reasons why updates sometimes fail on some users but focus on what you can do on your end. Because your phone no longer boots normally, or doesn’t allow you to load an app, creating a backup is out of the question. In an ideal situation, you are supposed to create a backup before you installed the update to prevent losing important data when a situation like this arise. Because you failed to do that, there’s no way you can recover whatever user data you may have stored in the phone’s internal memory.

As far as solutions are concerned, the only effective ones that you can try to do in this particular case includes wiping the cache partition and factory reset. These two solutions require that you restart the phone to recovery mode first. For details on how to do each of them, kindly follow the steps below.

How to wipe Galaxy S7 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 your Galaxy S7

  • 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 data / factory reset.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes — delete all user data’ 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.

Problem #2: Whatsapp keeps crashing on Galaxy S7 edge

I recently bought a new S7 edge from Dubai and on around the 23rd of February 2017, my WhatsApp crashed, in the sense that it opens for a fraction of a second and then closes. The data is all there and I keep getting chats from friends but i just can’t open it long enough to even open them. but if I am quick enough, I can access a chat or two after several tries. If someone sends me a message, it shows up in the status bar at the top of the phone and when I click on that, I can have a quick chat for a short time before it shuts down again. After many tries, I managed to get to the chat backup settings and managed to backup and change the setting to daily backup including videos. I backed up the phone and went to the Samsung store (when I got back to India) where they tried to reset the settings. When that didn’t work, they tried a factory reset. The gentleman restored the phone and Whatsapp but it didn’t change a thing. WhatsApp still refuses to stay open. It’s the newest update that they released.. With features similar to Snapchat. What do you suppose needs to be done here? Should I just ask the company to replace the phone? I’ve tried whatever options I could, at home and at the Samsung store. — Hayat

Solution: Hi Hayat. If this crashing issue only occurs when trying to use WhatsApp, that can be an indicator that the app itself is buggy, or that another app is causing to fail. To check if it’s the app itself that is causing the problem, there are two things that you can do.

The first one is to delete the app’s cache and data. Sometimes, an app’s cache can get corrupted or outdated so forcing the phone to create a new app cache may resolve the issue. Here’s how to do it:

  • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, click on an application.
  • 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.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

The other thing that you can do is try another round of factory reset and observe how WhatsApp works when it’s the only third party app installed. This means holding off installation of other apps after a factory reset so you can check whether or not WhatsApp works or not. If it does, you can assume that one of the third party apps is interrupting Whatsapp app when it’s working. To know what app may be causing the issue is not straightforward and requires further troubleshooting. You must invest more time and effort in identifying it. Unfortunately, the only way to do that is by installing one app at a time and observing how WhatsApp works.

On the other hand, if the problem persists after a factory reset, even when it’s the only third party app installed, the cause must be something deeper. If possible, consider having the phone replaced to fix the issue.

Problem #3: Galaxy S7 edge can’t read new SD card

Hello. I am from Romania (Europe). I just bought a new Galaxy S7 edge. I bought a new SD card of 32GB and mount it, format it. I put on it music and I set the camera to save the photos on the SD card. After 2 days of use when I wanted to see a picture after making it with the camera it denied to open it. And the music wasn’t no where to find it in my phone. Then I understood my SD card was no longer appearing. I reset the phone and the music appeared again but no pictures. This is happening for a few days now. I lost all my pictures I made till now. I changed the SD card to an old one I had of 8GB that was working good. If it acts as the first one it means the problem is with the phone, right? Do I have to send it to be fixed? Thanks! — Loredana

Solution: Hi Loredana. Troubleshooting an issue like this is simple. If the problem won’t occur when using a second SD card (the old 8GB card), that’s a clear indicator that the new SD card is defective. To fix it, try to reformat it on your phone first. If that won’t work, simply discard it and get a new one (or use the old card).

If, the on other hand, the problem continues even with the old or new second SD card, try doing some basic software troubleshooting first as the cause may be caused by a third party app or an unknown software bug.

The first one that you must do is to wipe the phone’s cache partition to tell the phone to create a system cache. Kindly refer to the steps above on how to do this.

If wiping the cache partition won’t work, you can then try to see if a third party app is creating a conflict by restarting the phone to safe mode. Safe mode blocks third party apps and services so if your phone will read the SD card normally, you can assume that one of the apps is problematic. To restart your S7 to safe mode, follow these steps:

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

Finally, if the issue persists even when the phone is booted to safe mode, performing a factory reset may fix the issue. As the name suggests, factory reset will return all software settings to their defaults. It will also wipe all user data like photos, videos, music, etc. so make sure to create a backup before proceeding. Here’s how it’s done:

  • From the Home screen, tap the Apps icon.
  • Find and tap Settings and then touch Backup and reset.
  • Tap Factory data reset and touch Reset device.
  • If you have screen lock feature turned on, enter your password or PIN.
  • Touch Continue.
  • Tap Delete all to confirm your action.

Now, we think factory reset will fix this issue but if, for some reason, the problem remains, consider having the phone replaced.

Problem #4: Galaxy S7 froze when recording a video | Photos and videos disappeared after Galaxy S7 froze while recording video

I was recoding a video on my S7, it froze. After a short time I tried to reboot but it wouldn’t shut down. The screen was black the power key top left shine blue and the two either side of the home button were illuminated. After a few minutes it shut down and I was able to power on. I recorded another video, all seemed fine. The next day I went to look at my videos to discover all the photos and videos had disappeared. I am using a PNY micro SD card. I’ve tried a reboot again, nothing. I’ve also tried the SD card in a computer, nothing. I can’t get onto my Samsung cloud either. I’ve had the phone since 23 December 2016. Please can you help. Thank you. — Yvette

Solution: Hi Yvette. If a second device like a computer can’t find your files in the SD card, or doesn’t seem to detect the SD card either, that’s a sign that it may had failed or had been corrupted for some reason. Try inserting it in another phone and see what happens. If the third device won’t detect or read it either, you’re out of luck as those files must be gone. The best that you can hope for is to see if the SD card can still be used after reformatting it.

To format an SD card, do the steps below:

  • From home, tap Apps > Settings .
  • Tap Storage .
  • Tap SD Card > Format.
  • Tap Format to confirm.

For your Samsung cloud issue, the best that you can do is to follow Samsung’s system in recovering your account in this page. Click on the “Forgot your password” link, enter and confirm the email you used to register, then type in the validation code.

Problem #5: Galaxy S7 Messages app only receives SMS from iPhone users but not from Android users

I was using the Message+ app for texting and decided to switch to Samsung’s message app for texting instead. It works great except for one thing. I can send texts out to anybody, but the only messages I receive back are from people that have iPhone’s. Anybody I know that has an Android phone will send a text back to me and it will only go into the Message+ app not, the Samsung app. I have made sure that the Samsung app is my default app and I have also turned off the Message+ app to no avail. Any ideas on why this is happening and how it can be fixed? — Renae

Solution: Hi Renae. It’s an odd issue and we haven’t heard of it happening so it must be isolated to your device. There must be some misconfiguration in how the software handles SMS so kindly refer the problem to Verizon. We don’t work for Verizon so we have no data if this is a known bug, or if there’s a solution that you can do on your end. Contacting your wireless carrier may help you fix it.

Problem #6: Galaxy S7 email won’t sync due to password issue

My e-mail account won’t sync, even when I try to do so manually. I have tried turning on auto-sync, and it looks like the app is syncing but no new e-mails show up. It shows the last sync as several weeks ago. I tried re-booting, clearing the cache, everything. Nothing is working. I also tried going into the email server settings, but a message comes up that “A security connection error has occurred.” I tried re-entering my password, but that didn’t work, either. — Jean

Solution: Hi Jean. If your password doesn’t work at this time, that may be the reason why there’s a sync issue going-on. Make sure that you know the correct password of your email by logging in to your webmail first (by logging in using a browser instead of the email app). Once you’ve resolved your password issue, we’re confident that the sync issue will go away.

To be sure, reconfigure your email in the app after resolving the password issue. You can also try to wipe the cache and data of the email app if you want to ensure that there’s no bug that prevents it from syncing properly.

  • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, click on an application.
  • 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.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

Problem #7: Galaxy S7 cannot save alarm after an update | Galaxy S7 slow performance issue, slow typing after installing update

I’m trying to set my alarm for the morning, and with the last update there was a giant save button that is no longer on the clock. I can’t find a way to save an alarm at all with the new update.

Also, the typing is incredibly slow. I’m currently writing this, and the keyboard doesn’t even catch up until I’m half way done with the sentence making it incredibly hard to detect errors in spelling. I really need an alarm to get up in the morning.  — Breanna

Solution: Hi Breanna. Whether you installed a security update or a major Android update like Nougat, we recommend that you do these steps to fix the problems you’re having (in this order):

  1. wipe the cache partition
  2. install app and system updates (if they are available)
  3. uninstall incompatible apps
  4. factory reset

We’ve already provided the steps on how to wipe the cache partition and factory reset above so make sure that you follow them.

The second possible solutions involve installing app or pending system updates. This will ensure that all apps are prepared to work with the current Android version running on the device. Keep in mind that installing an Android update does not necessarily mean that apps are updated as well. Outdated apps can lead to incompatibility issues which can manifest in slow performance and weird app behaviors. Make sure that you go over your list of apps and install updates that may be available in Google Play Store. We’re assuming that you don’t install apps from third party sources outside Google Play Store but if you do, it’s your responsibility to update them accordingly. How to do that depends whether a source has an available update for an app. Try to contact the developer if you aren’t sure if an app is compatible with the operating system you have.

Needless to say, you only need to install compatible apps. Bear in mind that not all apps are designed to work with all or with the latest Android versions. If you tend to install apps without checking possible compatibility issues, think again and visit the app’s Play Store page to read reviews from other users. Sometimes, developers will also indicate if their product is compatible with a particular Android version so watch out for that as well. The general rule is to ensure that you only install compatible apps.

We don’t know what alarm app you’re using so we cannot provide specific steps on how to save an alarm for you. Try doing some research on how to do that with help from Google.

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

Problem 1: Galaxy S7 won’t read SD cards after an update

So around a week or so ago, I upgraded my phone via a notification that popped up in the notification area. Afterwards, I started getting this unsupported SD card message. Seems like I’ve seen this happen in the past with the last OS version and would simply reformat the card since it seemed to be the easiest way to get things back to normal. Now, however, the phone will not format it. It tries and then delivers the message “command ‘7 volume partition disk: 179,0 public’ failed with ‘400 7 Command failed.” Every time I attempt another reformat, the first and last number (7 above) increment by one. The first logical conclusion that I came to was that the SD card is corrupt or bad. So I took it out and with a reader, attempted to access it with my Windows laptop. I could browse the card with no problem so I copied the data and then reformatted the card to FAT32. After reinserting into the phone, I get the same unsupported SD card message and so I attempted to format again. I get a progress bar that’s prepopulated at 20%, then the message above pops up. I, again, thought maybe it was the SD card so I tried another. Same thing….tried another….same thing. I’ve tried multiple cards no with no difference.  The first SD card is a Transcend 32GB Class 10 card and the other cards I’ve tried are all Samsung 8GB Class 10. The phone is running Android version 7.0. I have attempted the following with no change:

  • factory reset,
  • wiped the cache,
  • booted into safe mode, and reformatting the card using both Windows DiskManagement (both quick and slow method) and GParted.

A Google search returns quite a few hits related to this type of error message but no apparent resolution or cause. Everything is pointing back to the phone as the culprit, but I’m just not sure if it’s software in nature or hardware. My gut says it’s software since it started happening after the last upgrade and the fact that it appears to be manufacturer agnostic, meaning I’ve seen Sony users, Motorola users, HTC users, etc…. having the exact same problem.

Anyway, I’m hoping it’s a software as that would lead me to believe there is a possible fix for it. Any ideas? — Billyrwise

Solution: Hi Billyrwise. There’s no way to know for certain whether this type of issue is software- or hardware-related. The most that you can do is to see what you did previously that may have led to this problem. If you are positive that the only change to the system was the installation of an Android update, then you’ve probably installed a poorly coded firmware version. Since a factory reset did not fix your issue, the only solution left for you, other than a phone replacement, is by reverting the firmware to its previous version — Android 6. Be sure to use a good guide should you wish to flash an older Android version on your phone.

Problem 2: Galaxy S7 keeps restarting after using it under water

Hello. Today I went to a water park for my sister’s birthday, so i used my Galaxy S7 in the water, also under it. It worked perfectly all day. about an hour later I left my phone on the car and when we were leaving, it worked normally but it started to get very hot so i turned it off. Now it keeps turning off and on. It only shows the Samsung Galaxy S7 logo for a few seconds then shut back off and it keep doing the same thing without stopping. I can’t get it completely off or on. It also keeps getting hot even like that. — Alex

Solution: Hi Alex. First of all, a case like this is almost always hopeless because you are basically unable to do any software troubleshooting on the device. If the only different thing you did before was to use it in water, there’s a chance that its internal components may be compromised. Remember, an S7 is water resistant only, not fully water proofed. Any unnecessary water pressure (present when moving the phone under water) can force moisture inside.

Secondly, you want to try restarting the phone to other modes to see if you can stabilize it to an alternate mode. If you can’t, we don’t think there’s any other troubleshooting that you can do on your end. You must send it in for repair or replacement.

Below 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 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 3: Galaxy S7 unable to make voice calls and keeps getting error message saying SMS can’t be sent

I have a factory unlocked Samsung Galaxy S7 which I have owned for the past several months. Starting approximately two days ago, I began to be unable to make calls to certain people (the other people had both Android and Apple phones). This issue then escalated to where when I try to send a text message I get a sending symbol until eventually it says the message cannot be sent. However, my messages still appear to go through because people can reply to me and calls can be made to me. The issue is very annoying because I am constantly getting message not sent messages and it is also difficult to know when my message has genuinely not sent. I have tried a hard reset which wiped me to factory reset and I have also cleared my system cache. I have contacted my provider as well and they say everything on there end appears to be fine. Please help. — Devin

Solution: Hi Devin. Was there anything that you did differently before experiencing these problems like install an update or app? If you did, try to reverse it and see how it goes.

You can also try another factory reset and observe the phone. We know you already factory reset your device prior to contacting us but most people do it without observing their device afterwards. If you haven’t done that, here’s what you need to do exactly:

  1. Do a factory reset.
  2. Observe the phone for at least 24 hours. Test how sending text and voice calling works.
  3. Make sure not to install anything (app or update) during this time. The aim is to see if there’s any difference when the phone is running a clean software.

If SMS and voice calling works normally during observation period, that’s an indication that one of your installed apps is to blame.

On the other hand, if the problems remain during observation period, it can mean that there’s a glitch with the operating system or hardware. In either case, you want to have the phone replaced.

Problem 4: Galaxy S7 screen shows tan or sandy color

The screen has darkened. If I were to go on Google for example, the internet won’t be white and instead it is a tan or sandy color. It was working fine in the morning then I put my phone in my back and when I took it out, the screen is now a tan color. I don’t think water, dust sand, dirt ect caused this because my bag is clean and water has got on my phone before and the screen was fine but now it’s not and I don’t know what caused this or how to fix it. — Pegbuchunam15

Solution: Hi Pegbuchunam15. Pull up your phone’s service menu first by doing the following steps:

  1. Open Phone (dialer) app.
  2. Dial “*#0*#” (without quotes).
  3. Test how your device’s screen change colors by tapping Red, Green, Blue, and Black boxes.

If the screen remains the same, that is, it continues to show tan or sandy colors, you have a broken screen at hand. You should have the phone repaired or replaced.

On the other hand, if screen’s color change according to the box that you tap, that can mean that there may be an operating system problem. You should try a factory reset to fix it. Here’s how:

  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 edge stuck in boot loop

I have a Samsung Galaxy S7 edge which hasn’t been working for a week. It’s stuck in bootloop it won’t get past the samsung galaxy s7 edge screen at the start. I’ve tried putting it into safe mode to clear cache and reset the phone which worked previously when I had a similar issue, but this time when I press the buttons to go into safe mode it just comes up with a screen saying no command with a dead android guy. I’m starting to think the only other thing I can do is root my phone but I wouldn’t even know how to go about that. I hope you can help, Thanks in advance. — Danielle

Solution: Hi Danielle. If doing a factory reset via Recovery mode (check steps above) did not help, the only other option for you at this time may be flashing the bootloader and/or firmware. Below are the sample steps on how to flash a bootloader. The exact steps for your device may be slightly different so make sure to do some research how to do this. Flashing instructions vary by phone model. The steps below are for demonstration purposes only. If you don’t think you can do it, let someone with more advanced Android knowledge do it for you.

  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.

IMPORTANT: Flashing the bootloader or firmware can potentially brick your phone for good if not done properly. Be sure that you know what you’re doing before committing to it. You don’t need to understand how the entire process works but you want to be aware of the risks you’re taking.

Remember, flashing is not a guaranteed solution and there are lot of cases that it won’t help. If the problem stays, have the phone repaired or replaced.

Problem 6: Galaxy S7 keeps rebooting on its own after an update

My Galaxy S7 on EE network in Britain recently updated by the network. It worked normally for a while. I switched it off last week in the night and when switched on in the morning it just now keeps switching off and on. It stays on for variable times between 2 to 30 seconds max. I did the delete cache but still the same. I tried safe mode reboot but still the same. I have pictures and files on the phone I want to access but smart switch does not have time to connect to my new S8 I had to buy. The EE people in the shop say they can only wipe it and repair/replace since it is within warranty. Please help with any ideas to recover? — Gerzz

Solution: Hi Gerzz. You need a stable system in order to move files back and forth so we’re afraid you don’t have much choice in this matter. If you want to fix the issue though, you can try the suggestion we have for Danielle above. Flashing will delete the operating system though so you’ll still lose your data.

Problem 7: How to recover files from corrupted SD card in Galaxy S7

Hello. I have a Samsung Galaxy S7 and I save most of my pictures to a microSD card. One day, I noticed my camera album was missing, but didn’t think much of it. A little while later, I noticed that albums from a couple of large trips I had taken were gone. There are still some albums remaining and plugging the SD card into a PC gives no files other than what shows up when I open the file manager on the phone. Turning the phone on in Safe mode shows nothing additional either. Do you have any suggestions? Any data recovery program that you recommend (or will data recovery not do anything since there is still information on the SD card)? Any help you can offer is so greatly appreciated!! Thank you! — Kassie

Solution: Hi Kassie. Data recovery is a tricky business so there’s no telling what you might be able to get. If you think those missing files are worth a few hundred dollars to recover, we suggest that you visit Google to search for third party companies that offer data recovery service. Make sure to ask the terms of their service before paying so you’ll know what to expect. Some companies won’t charge you if they can’t recover anything but others may.

Problem 8: Galaxy S7 S Beam and NFC

My Samsung Galaxy S7 had a black screen issue after 6 weeks so it was returned and replaced. I received it in the mail and did the set up and restored it. After that was completed, I checked all my pics to clear them and make room to do the update. I had about 20 videos that was from my sister’s phone. I posted them to her on FB to get more room so I could do the system update, as space was needed. Everything was fine, except for the update loop, but that’s ok. The next day I went to look at the pics, since I had lost some from old phone and they were there. There was also about 100 of my sister’s pics now. We have never used the S Beam or NFC. It is driving us crazy how I got all them. Different phones, different providers, and they have never shown up for a restore before. All the pics and videos were from 2013, that’s it, no recent ones. Do you gave and clue what is going on? — Karen

Solution: Hi Karen. We don’t think we understand your point here. Can you please get back to us with clearer questions? We’ll update this post accordingly.

Problem 9: Galaxy S7 overheating and won’t turn on after it got water damaged

So I went swimming and since my phone is the Samsung Galaxy S7 I knew it was water proof. So I tested it in the pool but only put the phone under water for about 5 seconds tops. I dried it off after that and then set it aside in the shade and when I checked on it later it was already off. So I turned it back on but when I opened it it started glitching and switching between the home screen and the multiple tab screen (where it shows all the apps that are open). it kept doing that for a while and it kept shutting down because the battery was overheating until the battery died. Now when I charge it the battery sign shows up with a yellow triangle with an exclamation point in the middle. I looked it up and I know there is water damage because it said that under the battery there is a white square and if the square has red on it there is water damage. Now I just need help on how to fix my phone so I don’t have to pay for a new one or how much it will cost to fix it. –Arielrz2015

Solution: Hi Arielrz2015. First of all, your phone is not a water proof device. It’s only covered with water resistance protection, technically an IP68 certification, which means it’s not immune to water damage at all. Giving you the difference between water resistant and water proof devices is beyond the scope of this article so hit Google and do your research.

Secondly, the only effective solution (if you can call it a solution at all in this case) for a water damaged phone is repair. We can’t even be sure if your phone can still be fixed at this time. In an ideal situation, you’re supposed to turn off the phone, remove the battery, and dry the phone thoroughly to ensure that no moisture is left inside the device. Not doing them in the first place puts your phone in a uncertain situation. Depending on the affected component, the phone may or may not have permanent damage at this time so even a good technician may not be able to fix it. Anyhow, we strongly suggest that you have the hardware checked so you’ll be advised whether it can still be saved or not.

Finally, to prevent this issue from happening in the future, never ever intentionally expose your electronics to water, even if they have water resistance protection. You already know what can happen.

Galaxy S6 sound notifications not working right after an update, not charging properly, other issues

Hello Android community! Welcome to another episode of our #GalaxyS6 troubleshooting. This post brings you 11 more S6 issues taken from reports from some of our readers.

 

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

I just bought my Galaxy S6 less than 1 week ago. I noticed the day after I got it I was at work and my phone read 80%. It said I could not access the Internet without turning on my Wi-Fi. So I clicked on it. Then I had to click on “I Agree,” then instantly my phone powered off and was dead. Today I was at work and decided to turn my phone off while I was working and turn it on on my break. I turned it on and my phone read 97%. I went to the break room which is a 2 minute walk. When I got there, my phone was dead. What can I do to keep my battery from dying in a matter of a split second, to a matter of minutes. — Kim

Solution: Hi Kim. Is this a brand new phone? An issue like this is not supposed to happen in a new device so you should have it replaced right away. There’s a chance that the problem is being caused by a software or app glitch but still, you’re better off if you can have it replaced as early as possible.

If you happened to purchase a pre-owned S6, you may be out of luck. Most of the time, an issue like this boils down to bad hardware so you either have to have the phone repaired or replaced if you can’t fix the issue with a factory reset.  Below are the steps on how to factory reset your S6:

  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 Volume 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 2: Galaxy S6 Google Play app keeps crashing after installing Android Nougat

Hi.  After self-install to Nougat, my unbranded S6 doesn’t work correctly anymore. In particular Home button doesn’t work and block/unblock button works for a few minutes then it becomes useless. The only way to unblock S6 is a soft reset by pressing for 7 seconds block/unblock button and volume down together. I’ve noticed that Google Play appears when accessing camera and asks for settings. but it isn’t stable. It appears, then disappear and appears again…. it’s a mess because it overrides the other applications. And buttons stop working… Can you help me? Anybody did face the same issue? Thanks in advance Ciao Ivano from Italy. — Ivano

Solution: Hi Ivano. We’re curious what you mean by “unbranded S6”. We’re assuming though that you have a genuine Samsung Galaxy S6 because that’s the only S6 we support here. If you happen to have a fake Galaxy S6, please try to look for solutions elsewhere. We are not familiar with non-genuine Galaxy S6 so there’s very little to nothing that we can give you.

Assuming you have a genuine Samsung phone, the first troubleshooting step that you want to do is cache partition wipe. This will force the phone to delete the current system cache and build a new one.

  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.

Once you’ve cleared the cache partition, you then want to proceed with clearing the data of the Google Services Framework app. This is a necessary troubleshooting because you’re having an issue with a Google app. Here’s what you need to do:

  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 Google Services Framework app 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.
  6. Observe how the phone works for a few hours.

If the issue stays after doing the two procedures above, you must do a factory reset to return all software settings to their defaults. It is important that you observe how the phone behaves after a factory reset. You should let it remain as it is for at least 24 hours. Do not install any app or update during this time. Doing so will help you determine if the issue is being caused by an app, or if it’s something you can’t fix. If you’ll experience the same problem after a factory reset without any apps installed, you should consider repair or replacement. If the problem continues ONLY after installing apps, you should isolate the problematic app and never install it back.

Problem 3: Wet Galaxy S6 won’t charge, won’t boot up

My phone was slightly wet while charging. Dried off, let sit, plugged it back in. Light blue downloading screen came on. Would not charge with original plug in. Did a hard reset. Fixed that, still would not charge with any cord, original or otherwise. Came home, put on wireless. Charger showing charging, but phone’s charging light not red. After all night on wireless charger, now blinks start up screen, but nothing further. Will not boot up. Thank you. — Jennifer

Solution: Hi Jennifer. A Galaxy S6 does not have water-resistance protection like the S7 and S8 so even slight exposure to water can cause damage. If the current problem was not there before you got the phone wet, stop looking for software solutions and simply bring the device to a service center. The cause of the problem is most likely a damaged hardware so there’s no amount of software tweaks that you can do on your end to fix this.

Problem 4: Galaxy S6 edge not turning back on

HI there. My Samsung S6 Edge was sitting on my bedside table this morning, and when I went to check emails while lying in bed, the screen went sideways (as it always does when the phone is not completely upright), and I pushed the home key a few times because the screen seemed to have frozen and I was trying to get it back to the home screen. And then it went black, looked like it was starting to either turn on or off (the Samsung logo came on), then went completely black and won’t turn on and I don’t think it’s charging.

The battery icon with a lightning bolt appears, but no lights are on, and the icon is just grey. I have had it plugged in for a while now, and have tried to doing the soft reboot, etc, but nothing changes. It just seems to have completely crashed. I have plugged it in to the wall and also my laptop, but the same thing happens with both. I’ve only had the phone a few months, and it has been working fine with no problems. Thoughts? — Emily

Solution: Hi Emily. Try leaving the phone connected to the charger a little bit longer, then try to see if you can turn it on to alternate modes. Only then can you attempt to do a software fix. If your phone remains dead and unresponsive, you should have it repaired or replaced.

Below are the steps on how to boot your phone to alternate 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 5: Water damaged Galaxy S6 not turning on

I was pushed into a swimming pool of 5 feet and my phone was in my back pocket. While in the water I realized I had my phone so I quickly tried to resurface and place my phone to outside out of the pool before any more water got in. As when I finally got my self out of the water I noticed my phone wouldn’t come on . It stayed in a box of rice a ron i because I wasn’t able to get regular rice, over night bit it still hasn’t come on . It’s it possible for it to still turn on and what can I do. — Reanna

Solution: Hi Reanna. Putting a wet electronic device in a bag of rice won’t do much, especially since the phone’s battery was not removed. In an ideal situation, you are supposed to do the following:

  1. Turn the device off immediately.
  2. Remove the battery right away (we know this is not easily doable since your S6 has a non-removable battery pack). Leaving a battery connected to a wet motherboard can short components and lead to permanent damage.
  3. Dismantle the phone and separate the motherboard from other removable pieces.
  4. Clean the components with alcohol.
  5. Dry everything in a bag of rice for a few days.

As you can see, the drying part comes last. Not doing the first four steps would lead to problems so what you did does not really matter at this time. All the five steps mentioned above all constitutes as a “first aid” procedure and not be as permanent fix.

If you want to know if your phone can still be saved, you must let a professional check it. Make sure to send it to a good service center.

Problem 6: Galaxy S6 not charging properly

Hi. I am experiencing a frustrating issue with my Samsung Galaxy S6. Last night my phone died and tried charging it when I got home. When I plugged it into the fast charge adapter the power bar that is displayed when the phone is off immediately jumped to 90%. After about an hour it was still at 90% . I tried to turn on the phone. It would go through the startup cycle to the Samsung Screen and turn off and go back to the power bar at 90%. I have tried different cords and chargers. The very interesting thing is different chargers display different percentages. My car charger this morning started at 20% and actually charged to 75% before I got to work. A non-fast charger starts at 35% and moves up very very slowly. The fast charger starts at 90% and stops at 91%. Have you seen anything like this before? Any suggested solutions? I have tried rebooting, wiping the cache, basically everything you have suggested in all of your other phone not charging posts short of the factory reboot. Thanks. — Matt

Solution: Hi Matt. There may be a software glitch causing the operating system not to detect the true battery level. To check, try calibrating the battery first and see how it goes:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.
  10. Observe how the phone charges for a few times.

If battery calibration won’t work, do a factory reset.

Problem 7: Galaxy S6 sound notifications not working right after an update

Since doing the last update on my Galaxy S6, the notification sounds for my calendar only do a 1/4 to 1/2 of the sound. Same problem when someone calls, it might ring once or just a short amount and then stop. But if you look at the phone you can tell it’s still “ringing,” but with no sound. The other thing that happened, is that any video recording I do with sound is beyond “crackling.” I have never dropped my phone, it hasn’t been in or close to water or in the sun. All this happened right after the last update. Any info on how to rectify the situation would be greatly appreciated. Thank you. — Simone

Solution: Hi Simone. Make sure that you do the basic software troubleshooting for update-related problems — cache partition wipe and factory reset.

Once you’ve factory reset the device, make sure that you only install apps you’re 100% sure that’s compatible with the operating system. We assume you only install apps from Google Play Store so you want to check their installation page or contact their developer if you’re not certain. Most popular apps from known companies are most likely compatible so you can skip them. Try to focus your efforts on apps from unknown developers. Keep in mind that not all apps are created equal. It’s up to you whether you install an incompatible or problematic one or not.

Problem 8: Galaxy S6 randomly fails to read SD card

I am having a strange issue where my Samsung Galaxy S6 will not recognize my 128GB micro SD card. It tells me that my SD card is corrupt. It will recognize it sometimes but if I restart my phone after it recognizes it, it goes back to saying its corrupt and I have to restart the process of trying to get it to recognize the card again.

I have put this card in my computer and my computer says the card is fine and I can use it as normal and access everything on it. My phone will recognize all my other micro SD cards except this one. With this card I have to keep reinserting it until my phone recognizes it. Most of the time, I have to let my phone cool down before it recognizes it but not in all cases.

I have been noticing that it’s been getting harder to get my phone to recognize it. I am afraid to reformat the card on my phone because I am afraid I will lose some of the memory space on it. So instead of having 119GB of usable memory, I will lose some of those GB and not have the full 119GB I should have. I don’t know if that would actually happen or not but I do know that if I reformat my card I lose all data on the card and I have backed up everything on the card.

Please help me fix this issue. If there is any additional information you need just let me know Thank you! — Tyler

Solution: Hi Tyler. You know for certain that the problem lies on the SD card so we recommend that you either reformat it, or simply replace it. There’s really nothing much that you can do except these two things.

Problem 9: Galaxy S6 stuck in Samsung logo screen after unrooting

Hello. I need help. My Samsung phone was rooted somehow so I unrooted it thinking that that would solve all my problems. About 24 hours after unrooting it, it seemed to crash, it starts up and then just stays on the Samsung screen with the little blue things bouncing off it.

I have tried every single restart thing, factory reset, all the tricks of the trade on Youtube and nothing has worked. I even sent it to someone to have a look. They tried to put new software on it but that didn’t seem to work. I am at the point of giving up and buying a new phone but the phone was in perfect condition so I am willing to try anything. I feel like I might have some sort of hope with you guys but I’m not too sure. Have you had this problem before? What else can I do? It’s a Samsung Galaxy S6, and the warranty has run out for it. — Ruth

Solution: Hi Ruth. Rooting is basically a modification of Android operating system to give a user access to core and normally not accessible system files. There are a lot of rooting software in the wild so there’s no one-size-fits-all solution for any rooting issue. Unrooting, like rooting, can lead to problems if not done correctly. We don’t know what you did exactly to unroot your device so there’s not much that we can offer. We suggest that you try to flash the bootloader for this device first and see how it works. Below are the general steps on how to flash the bootloader:

  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.

NOTE: The steps above may not be the exact steps on how to flash the bootloader on your phone. Flashing instructions can vary by phone and phone model so make sure to do some research first so you’ll have a good guide.

If flashing the bootloader won’t fix the problem, try flashing a stock firmware on your phone.

Problem 10: Google contacts not showing in  Galaxy S6 Contacts app

Dear Sir or Madam, Hope you had a nice weekend. I have a problem about my phone Galaxy S6.

Contacts app: The phone’s Contacts app can’t display the contacts from my Google account. It happened 4 days ago. I think all the contacts I entered from the phone Contacts are still there; all the contacts I entered from my Google account are no longer in the phone Contacts app. For example, a number ending 223: this contact is from my Google account, but now it can’t display the name in my phone Contacts app or in the phone Messages app. The name can be displayed before. I have tried Sync again and again, but it always shows it is Synced. If you could kindly help with this issue, it would be very helpful. Many thanks in advance. Best regards. — Yue

Solution: Hi Yue. Try wiping the cache and data of the Contacts app first (make sure to back all your contacts first) and see what happens. If the problem is still there, sign out of your Google account, then sign back in.

If that won’t solve the issue either, do a factory reset.

Problem 11: Galaxy S6 can’t send a reply text

Hi. I have recently acquired a Samsung Galaxy S6 as it is more up-to-date than my iPhone 3. I stayed with the same carrier so just had to put my SIM card in and go through start up. The phone works fine other than it fails when replying to texts. I have gone through your instructions on the S6 including doing a factory reset and have also spoken to my carrier to make sure that my plan is ok. I have also tried the SIM on another Android phone and it worked ok. What I have worked out is that on the S6 I can’t reply to a text or send a text that has a country code in the number. If I drop the country code I can send a text to that number but obviously this is more time consuming than just replying to a text, and also means the text conversation is interrupted. I have also used GSM codes to make sure there are no bars on incoming or outgoing calls or texts. In Australia, the S6 only runs on Lollipop as Marshmallow is not available. Thanks. — Malcolm

Solution: Hi Malcolm. An issue like this must be resolved by your carrier so we’re wondering what they did to help you. Since a factory reset did not fix your issue, the only workaround that we can suggest at this time is that you try another messaging app. If that won’t fix the problem either, talk to your carrier again and let them fix it.

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

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.

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

Problem 1: Galaxy Note 4 can’t read 512GB SD card

Can a Samsung Note 4 use a 512GB SD card? I have been trying to transfer several hundred MP3 files to a 512GB SD card. When I format the card with Windows 7 and transfer the MP3 files to it, the computer reads them just fine. When I mount the SD card in the Samsung Galaxy Note 4, it does not show the files and announces that the card needs to be formatted. It does not give me any choices regarding type of format. I suspect the Windows 7 format will work with the Android phone. Is the correct? Can a Samsung Galaxy Note 4 android phone address a 512 gb SD card? — Phillip

Solution: Hi Phillip. A Galaxy Note 4 can only work with a microSD of up to 256GB. Even a Galaxy S8, the latest Samsung flagship, can only read a 256SD card so you’re out of luck. You can keep the card though for more advanced devices in the near future.

Problem 2: Galaxy Note 4 keeps rebooting, volume increases on its own

My phone just one day it wanted to keep turning itself down. And my Bluetooth decided it didn’t want to work either. I have a bluetooth device in my car, and doesn’t work. I tried putting my phone in safe mode, but the problem still occurs. I cannot seem to figure out the problem. I could be using my phone with all volume systems turned all the way up, and then no sound, then it will gradually turn back up.. please send help. It does it while using Spotify and Facebook. — Destiny.n.osborne

Solution: Hi Destiny.n.osborne. The most that you can do when it comes to your issues is to factory reset your Note 4. There may be an app or operating system bug that cause the said problems. If you haven’t tried doing it before, here are the 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 the Galaxy Note 4 completely.
  3. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  4. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  5. When the Android System Recovery shows on the screen, release the Vol Up key.
  6. Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  7. Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
  8. When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  9. The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.
  10. Check how Bluetooth and volume work afterwards. Make sure not to install any app during this time. If both problems stay, it’s time to send the phone in for repair or replacement.

Problem 3: Galaxy Note 4 becomes very slow, keeps getting TouchWiz has stopped responding error

This morning phone was slow to respond. Finally got message that TouchWiz stopped responding. Phone spontaneously rebooted a few times but would not wake up after lockscreen engaged and display turned off UNLESS I connected it to the car charger. I intentionally powered off. Powered up. It powered itself back off. I found directions for soft reset. Removed battery, held power button for a minute. rebooted. It went through an obvious reset cycle and came to a no-frills black screen with options, including reboot. Chose that using power button. All seemed well until it shut itself off. Now what? I’m unsure of the Android version – it should be on whatever the latest and greatest AT& T has rolled out to me. — Amelia

Solution: Hi Amelia. The first troubleshooting step that you need to do is to clear the cache partition. This is to force the phone to delete the current system cache and replace it with a new one. A corrupted cache can sometimes cause issues so it’s good if you can eliminate it from your list of possible causes. Here’s how to do that:

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Vol Up key.
  5. Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  6. When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

If clearing the cache partition won’t fix the problem, then your next move is to wipe the phone clean with factory reset. Steps are provided above.

There were a few cases in the past where some users were able to fix a problem similar to yours by installing a third party app to minimize wake locks. If the problem remains even after a factory reset, try to use Wake Lock by Darken from Google Play Store.

Problem 4: Galaxy Note 4 won’t boot past Odin mode, stuck in Download mode

Phone keep saying downloading do not remove from target and it also says no command at times. What do I do to fix my phone? I tried factory reset, but when I apply it nothing happens, but the phone turn off completely and I have to take the battery out to restart it every time. and when it do come up the Android guy be on its back and come up to system recovery at times. and I press reboot system, but things are still there same. — Pgrisby36

Solution: Hi Pgrisby36. If nothing happens when you attempt a factory reset, you should try to flash the bootloader. This is a logical next step since your phone appears to boot only to Odin or Download mode. Flashing requires a few things including a computer and an Odin program for the PC. Make sure that you do more research on how to do it. Below are the sample steps on how to flash a bootloader. Exact steps may vary so find a good guide for instructions. The steps below are for demonstration purposes only:

  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 5: Galaxy Note 4 has no sound, Youtube won’t play

Hello. I have a SFR Samsung Note 4. It has been causing problems since last year, and I tried everything — reset to factory, the hard reset, bought a new battery, nothing works. Same issue. No sound, don’t know why. Youtube is not loading at all. if you browse the internet, it works to an extent then it freezes and goes black. You can’t make phone calls, it delays in calling, or if I get an incoming call, the screen appears with almost 2 min delay, and once it appears it won’t let me take the call, like literally swipe the green call sign. What else can I do?

I don’t know how to use Odin and install a new operating system on it, but I think this won’t do the job either. Once I had a hard reset of it, it asked for an update, but without or with the update version, still same issues. Can you help me? — Wlf.david

Solution: Hi Wlf.david. Your phone appears to have a general software or hardware issue. We don’t know anything about your device or its history so there’s nothing much that we tell you. Please refer to our suggestions for Amelia above. If nothing will change after doing all of them (cache partition wipe, factory reset, and installation of Wake Lock app), it’s probably high time to replace the device.

Problem 6: Galaxy Note 4 shuts down when taking a picture, overheats when using flash light app, battery doesn’t charge to 100%

Hey there. I’m all the way from Guyana South America and I’m having a few problems with my phone, Note 4. I bought it second hand “refurbished.” The problems are listed below:

 

  • The phone doesn’t charge to 100% unless I clear the cache, it usually charges to around 50-70%. Also, I do use an original Samsung fast charger
  • Whenever I use the camera, sometimes to take one or a few pictures the phone shuts down. Also when I play real moto it shuts down.
  • If the phone battery reaches around 15% it shuts down and when I put it to charge it show 0%
  • when I use a flash light it gets extremely hot. I have already replaced the battery, wiped cache partition several times and did one factory reset. I have downloaded a few other apps including CM security which I don’t really trust. — Abdel

 

Solution: Hi Abdel. The only software troubleshooting that we will suggest for you is battery recalibration. If that won’t fix the issue either, there must be a deeper issue with the hardware that causes all these problems. All four issues appear related and can have a single cause. If a battery recalibration can’t fix it, you must have the phone repaired or replaced.

Here are the steps on how to recalibrate the battery:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

Problem 7: Galaxy Note 4 keeps restarting on its own

I have the Samsung Galaxy Note 4 and I’ve gone the few 4 replacements going on the 5th after only having it 2 days with the same problems with all of them. It’s driving me crazy. My phone turns on and off on a daily basis even with a full battery. It will not completely turn on at times. I have tried to reset it multiple times and have taken out the battery to try to get it turn back on. I have also bought a brand new battery and it didn’t help the problem. Any idea how I can fix this problem? I have also updated the phone when they become available. — Munozcbn_1983

Solution: Hi Munozcbn_1983. It’s very unlikely that the same exact problem can occur on at least 4 phones unless you yourself is causing it. The main reason may be due to a bad app that you install after setting up your phone. To check, try to boot the phone to safe mode and observe. Safe mode blocks third party apps and services so if the issue won’t occur while safe mode is enabled, that’s a confirmation of our hunch. Here are the steps on how to restart the phone to safe mode:

  1. Turn off the phone completely.
  2. Press and hold the Power key and the Volume Down key.
  3. When the phone starts to boot, release the Power key but continue holding the Volume Down key until the phone finished restarting.
  4. Safe mode will be display at the lower left corner; you may release the Volume Down key now.
  5. Observe the phone for at least 24 hours.

You can also try to factory reset your device and observe how it works when there are no third party apps installed. Like in safe mode, you must observe the phone for a minimum of 24 hours to see a difference. If the issue is absent, uninstall apps one by one until you identify the culprit.

Problem 8: Galaxy Note 4 keeps restarting after Android 6 update

Hello. I had received an Android 6.0.1 update after which phone started restarting abruptly. Contacted Samsung service center who concluded that motherboard is faulty. But when i asked them to explain how can an update destroy the hardware, they had the only answer that, if they can’t re-flash the Android then it should be concluded as motherboard issue, as they are trained to tell that.

I took the phone back and did a research on Google and found that this problem is profound everywhere in the world and one gentleman had suggested a solution for this. The solution from him was to install an app called as Wakelock and set it to some mode. To my surprise, that worked 100% and phone was back to normal when operating in active condition. But if i try to restart it, the app would be inactive thus until i struggle and switch on the phone and reset the app to the above said mode, the phone doesn’t work properly.

Meanwhile, when i spoke to Samsung customer care, they said that they have released a new update, which solves this issue. So i waited for the update and finally i got this new update and i tried to install it. As soon as i gave install, phone went into boot mode and then it never recovered after that. the phone is dead now. Completely dead. tried all the basic steps, like soft start, safe mode, recovery mode. nothing is working. checked the battery voltage using a Multimeter and its delivering the required voltage. Please solve my problem. — Sharath

Solution: Hi Sharath. Installing a third party app like Wake Lock to fix a certain issue is  never a permanent solution. Unless the main cause of the problem is addressed, you can expect that it will return.

We know nothing much about your phone’s history including the possible reasons that may have led as to why your Note 4 now fails to power back on so it can really be anything at this point. We know that there are a lot of Note 4 users that find their device working fine after installing Android’s latest update, we always expect to receive reports of problematic cases simply because Note 4’s hardware was designed to work with older Android versions. Installing the latest Android iteration to it can put a strain on the hardware, leading to all sorts of problems. There’s never any official Samsung explanation why there a lot of Note 4 devices failing after an update but the general rule, if a broken device can’t be fixed by software troubleshooting, bad hardware must be to blame.

If you haven’t tried it yet, we suggest that you manually install the older yet working Android version for your device. We know this is not ideal but it’s the only effective way to allow users of Note 4 to continue using their devices that suffered problems after installing Marshmallow and/or Nougat.

Problem 9: Galaxy Note 4 screen showing green strip on top, screen remains black and won’t turn on

I had my phone in my bag on a chair and when I went to go get it and my bag was on the floor. There were scratches on the front of it. The screen is totally black but when I 1st tried to turn it on there was a green strip on the very top of the screen that appeared. There is a blue light blinking on top (like my email notification) and the lights at the bottom still work. I have the Samsung Galaxy Note 4. — Brittany-cats

Solution: Hi Brittany-cats. Boot the phone to Recovery or Download mode and check if you can get the screen to work normally. If that green strip on top remains when the device is on Recovery or Odin mode, you’re out of luck. That’s a sign of a damaged screen and you must have the phone repaired or replaced. The same is true if the screen stays black and won’t show anything.

Here are the steps on how to boot the phone to Recovery Mode or Download mode:

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.

Problem #1: Galaxy Note 4 won’t read SD card, keeps saying it’s corrupted

Hi! Thanks for offering to help! I have a Note 4 that I have been using for a couple of years. I have used a micro SD card during this time for photos and other files. The phone recently stopped recognizing the card. I pulled the card and checked it on my PC and it is fine. All the files appear to be there. I put the card back in the phone and under the Storage section of Settings it now says the SD card is corrupt. I don’t know if it said this before. It appears the card is fine because the files all show up on the PC. Could there be a problem with the phone instead? Any insight is appreciated. Thank you! — Sabins4

Solution: Hi Sabins4. We can’t eliminate the possibility that the phone may causing the problem so you must narrow down the causes on your end.

The first thing that you want to do is to create a backup of your important files in both the SD card and phone. This is a must-do step whenever you troubleshoot memory issues. Of course, we assume that you regularly create a backup of your files as storage devices can fail without warning.

Once you’ve copied your files in a safe location, the next thing that you want to do is to insert the SD card to your Note 4 so you can format it. It’s important that you format an SD card using the device you’re planning to insert it to to minimize bugs. To format the SD card, follow these steps:

  1. From a Home screen, tap Apps (located in the lower-right).
  2. Tap Settings.
  3. Tap Storage.
  4. Tap Format SD card.
  5. Tap Format SD card. If presented, enter the appropriate password, PIN or pattern then tap Continue.
  6. Tap Delete all.

Once you’ve reformatted the card, load your files to it and observe how it works for a few days. If the problem persists right after you’ve formatted the card, unmount it from the phone and check it on the computer. If a second device can read it fine, the problem must lie on the phone itself and not on the card.

To fix the problem, do a factory reset and see if it works. Here’s how:

  1. From the Home screen, tap the Apps icon.
  2. Find and tap Settings and then touch Backup and reset.
  3. Tap Factory data reset and touch Reset device.
  4. If you have screen lock feature turned on, enter your password or PIN.
  5. Touch Continue.
  6. Tap Delete all to confirm your action.

Should the issue remain even after you’ve reset the phone, consider sending the phone in so it can be replaced.

Problem #2: Galaxy Note 4 not receiving SMS from one number

Hello. After an update I cannot receive texts from just my daughter! She has an iPhone. I’m with T-Mobile. They tried clearing the cache, didn’t work. I deleted my daughter’s info and then added her back, didn’t work. T-Mobile can’t figure it out. They wanted me to do a reset but I have lots of texts messages from my niece who recently died and I don’t want to lose those texts and screenshoting them all is very difficult. Now they want to give me a refurbished phone and hopefully they can transfer my text messages from my niece over. What do you think? AND are refurbished phones OK? My niece bought me this phone, I hate to give it up. Thank you so much for your help. Sincerely. — Helen

Solution: Hi Helen. We’re afraid troubleshooting this issue involves wiping the messaging app’s cache and data, which means deleting your messages (SMS and MMS) as well. To preserve your messages, we suggest that you back your phone up with using the official Samsung Smart Switch first. You need to install this app on both your phone and computer to work. Once you’ve created a backup of your files and messages to a computer, you then need to start troubleshooting your phone.

Make sure inbox is not full. Be sure to check that there’s enough space to receive more SMS and MMS. A messaging app’s allocated storage is not unlimited so if you are fond of keeping years-old conversations, your inbox may have become full at this time. To make more room, simply delete a few old conversations. If you are absolutely sure that there’s available space in your inbox, just skip this step.

Check if there are no blocks. Go under the settings menu of your messaging app and make sure that you are not blocking your daughter’s number. You also want to check that there are no blocked phrases that can prevent your phone from receiving messages.

Check the spam folder. Sometimes, a message will be forwarded by your system to its spam folder, or blocked messages folder, so be sure to check it as well. Messages or numbers marked as spam before will automatically be sent to this folder.

Boot in safe mode. If you are fond of installing apps, chances are one of them is causing this problem. To check if that’s the case, boot the phone to safe mode. Safe mode blocks third party apps and services. Here’s how to do it:

  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.

Be sure to let the phone run in safe mode until you can replicate the issue. Ask your daughter to send you another message and see if you can receive it while the phone is in safe mode. If your phone will get the SMS, that’s proof that a third party app is blocking your daughter’s message. Why that is so is for you to find out. In the meantime, try to fix the problem by uninstalling third party apps until the issue is eliminated.

Delete the cache and data of Messages app (or whatever messaging app you’re using). If the problem remains even when your phone is on safe mode, the next thing that you want to do is delete the messaging app’s cache and data. Here’s how to do it:

  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.

Do a factory reset. If all else fail, wipe the phone clean via factory reset. 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 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 #3: Galaxy Note 4 lost Gallery folders, Gallery app won’t work

On my Galaxy Note 4 lost access to my GALLERY photos. Only photos I can access are on the Camera and downloaded (saved to my phone) from texts messages. Any new photos I take are there under Camera. All photos I took before went to the Gallery. Got message it was ” Unable to open Gallery” the other day.

I removed battery after shutting off and reinstalled it, but that did not change anything. Battery was not low, near full charge at the time. Tried going to Settings>Applications> Gallery to see if that would bring it back, but that didn’t help. Tried to download the DCIM folder on my computer…. (usually where all the photos show up from the Gallery ) Opened it and saw two other folders never seen there before! These had nothing inside them.

Also noticed all the other folders on the phone showing on the computer had a backwards letter U in front of each name, like udroid instead of Android, uost instead of Host, etc. A corruption of some kind?

All the other Apps still work OK. Still can get Internet as well. Just the Gallery disappeared. Never had any issue like this before. Thank you in advance for any help. —  Jim

Solution: Hi Jim. There’s no way to know for sure what caused the disappearance of your folders or the erratic behavior of the Gallery. It can be due to a bad app or a software bug. The first thing that you want to try is clearing of the cache partition. If that won’t work, consider wiping the phone via factory reset. Any of these two should help fix the problem. Factory reset returns all software settings and databases to their defaults so the pre-installed Gallery app will be restored to its known, working state.

Problem #4: Galaxy Note 4 screen remains black after an accidental drop

I dropped my phone on a tiled floor about a meter from the ground and then the display went off. Well the batteries came out of as it fell down. when I picked it up and put the batteries in, instead of working well like it should, the phone wouldn’t turn on. so later, I could see the purple and blue notification sign. light is still there as well as the fact that when I put the stylos/pen back in the phone it vibrates like it does. Else I don’t seem to be receiving calls or anything but I know that my phone is on and working because when I connected to my already open web Whatsapp page it was connected although it doesn’t show up on my laptop when I connect it via usb. I don’t know what to do to be honest. please help. — Midhat

Solution: Hi Midhat. If the screen remains black even though the phone seems to be powered on, that means that the accidental drop damaged the screen assembly. There’s no software fix for this type of problem so make sure to send it in to Samsung. If you’re lucky and the damage is limited to the screen assembly only, a replacement of a screen may easily fix the issue. Otherwise, a replacement unit may be needed to give you a good working phone again.

Problem #5: Amazon app won’t work when Galaxy Note 4 is connected to wifi

I have several apps that require internet to use and make sure that I am under a wifi connection to use them. But when I try to connect to them, it says that I need a better connection to use them. I cannot get these apps to work, no matter what I have done to get them to work. even some web pages will not load because it says that I am not using a secure settings, but I have not changed anything on my phone. I am not sure how to fix the settings or fix the apps so that they will use the wifi and not the data on my phone. The apps I am trying to use are Amazon app and it says it is not secure. If you could help to fix it that would be great.

Also a note… I got this phone recently from my mother and did not do a factory reset because she had some apps that I wanted to keep. — Momof6

Solution: Hi Momof6. We can’t see a logical reason why an Amazon app won’t work on wifi connection  unless there’s something on the phone itself that causes the problem. If your phone is not rooted and does not run a custom ROM (in other words everything is official), we suggest that you contact Amazon so they can help you troubleshoot the issue. There may be a coding problem that only them can fix.

If your phone is rooted and does not use official software, that may be the reason why apps that require a secure connection doesn’t work as expected. Revert everything to stock before attempting to install apps again.

Problem #6: Galaxy Note 4 shuts down when camera is used and battery level is low

Basically, I’m having all listed problems with my Galaxy Note 4, but the copied question matches my issues the most. T-Mobile has replaced my phone 3x now, and each one has the same issues. I basically can’t use my camera without my phone shutting off. If I’m at 40% or less, my phone will shut off and power back on repeatedly or just stay off until i take the battery out and put it back in. Here is the question I copied that is most closely related to my situation. “When my battery percentage reaches in the 50s (not while using any specific app or the internet etc) phone shuts off and won’t turn back on until I plug it in. Then it when I do plug it in, it shows around 40% or so. I have replaced the battery, done a soft reset, cleared the cache, deleted several apps, done a factory reset, and it still has the issue.” I’m at my wits end with the Note 4. I never had these problems until after the Marshmallow update. After that, every single Note 4 that I’ve had, gives me the same issues. —Wirelessamber

Solution: Hi Wirelessamber. If the problem happens on at least 3 different units, its cause must either be an app that you install or inefficient coding of the software.

The first thing that you want to try is to observe the phone while it’s booted to safe mode to see if a third party app is to blame. Because this issue can also be caused by a pre-installed app, there’s no way that you’ll know it. Safe mode only works for third party apps so if nothing changes when you boot your Note 4 to it, you must try a factory reset as the next step.

If factory reset won’t make a difference, you can assume that this is a firmware bug. Since you download updates by air, there may not be a solution right away from your carrier. If you are really desperate to make the camera to work, try to manually install a previous Android version, the one that didn’t have this problem before.

Manual installation, also called flashing, is a risky procedure which can potentially brick your phone. Make sure to do some research before you do it.

Problem #7: Galaxy Note 4 randomly reboots and overheating due to wrong firmware

Hi. I have a Note 4 previously owned and the person put the wrong firmware on. Now the phone still work but constantly reboots, overheats and the screen has a yellowish tint on 3 quarters of the screen. And where the notification area is you can see the real color the screen is meant to be.

Now i can’t update my Note 4. i presume its because of the firmware. And I’ve tried using Odin, Samsung Kies and Smart switch and they all have failed. Is there anyway i can upload new firmware or any other solutions? I’ve been struggling with this issue for more than 2 months now and can’t get a break through. The Samsung store in our town is useless because they have no knowledge about dealing with any of this.

My Note 4 was running fine until the 6.0.1 update came out. Then it went completely down hill from there but if i can get a way to some how get the right firmware on i think it might fix the problem. — Joshuagrant1132

Solution: Hi Joshuagrant1132. The only effective way to manually update a firmware on a Samsung device is by booting it to Odin mode and use a computer to reprogram the device via Odin application. We don’t provide a full guide on how to flash a firmware as the steps vary from phone to phone. You have to do some research on how to flash your own phone. Keep in mind that firmware can vary a lot even on the same phone lines as the Note 4. in other words, you can’t use a T-Mobile firmware in an AT&T Note 4 so make sure that you use the correct firmware. You also need to use the right guide on how to flash a particular firmware as even a small misstep can lead to complications. If you want to do the flashing yourself, use Google to find a good guide for this task.

Problem #8: Multiple issues on Galaxy Note 4 after deleting bloatware

A week ago I was cleaning up my phone deleting and disabling bloatware etc. Since my Pebble Time watch disconnects every few minutes I often need to manually reconnect. Other times it showed not connected on the phone but the app shows it connected.

Also my Nixie clock widget is mostly displaying the wrong time even though the correct time is always visible upper right of screen. My Internet Speed Meter app always showed speed upper left of screen. Now only does for a few minutes after I manually open the app. WiFi Manager app doesn’t show the correct information in the widget. Often Shows connected when not and not connected when it is. Also often when I’ve changed to a different WiFi connection the widget still shows the last one. Several other similar things with apps as well as just locking up periodically for a several seconds. All these anomalies started at the same time. BTW this is a Note Edge but I didn’t see it in your choices. And when I’m in USA I use Cricket network. – Acme71

Solution: Hi Acme71. If all these problems started happening all at the same time, there must be a software glitch causing it. Be sure to revert the software settings to their defaults by doing a factory reset. Refer to the steps above on how to do it.

Problem #1: Galaxy S7 edge can’t send group message

Since switching from an iPhone to a Samsung Edge S7, I have not been able to properly send group text messages. Typically the recipients are receiving my text messages as individual text messages. I’ve checked that the “group conversations” is enabled by default, so that is not the issue. I have also tried to put this SIM card back in my old iPhone and shut off iMessage, then putting the SIM card back in the Edge S7 and that didn’t work. What in the world is happening? Thank you! — Brad

Solution: Hi Brad. There are three requirements that must be met in order to send and receive group messages successfully.

The first requirement involves the sending phone being compatible with this feature.

If the sender’s phone does not support group messaging, group messages will be received by recipients as individual text messages. The Galaxy S7 supports group messages and here’s how to send one:

  1. From any Home screen, tap Messages.
  2. Tap the Compose icon.
  3. Tap the Contacts icon.
  4. Drop down and tap Groups.
  5. Tap the group you want to send the message to.
  6. Tap Select all or manually select recipients.
  7. Tap Done.
  8. Enter message text in the Group conversation box.
  9. When done, tap the Send icon.

The second requirement involves the receiving phone and, like the first one, must also support the said feature. If the receiving phone does not support it, you’re out of luck. For example, if the receiving phones are iOS devices, they may not be able to join a group message when there’s an Android device member. Group messages sent from Android phones don’t usually have problems with group messaging but iOS devices like iPhones may be problematic. iOS does not support group messaging feature aside from its own messaging platform or iMessage. If the recipients of your group messages are using iMessage to receive your text, they will only be able to receive regular SMS from you.

Thirdly, carriers of both parties (sender and receiver) should support the group messaging system you’re using on your phone. SMS and MMS are coursed through computer systems of both carriers and if one does not recognize the request to keep the message as a group, some members may only receive your group text as regular SMS. If the first two requirements are met, the most likely reason is this one.

Problem #2: Galaxy S7 NFC contactless app stops working after system update

My NFC contactless application works properly only until I get a system update or I reboot my  phone and then it stops working. The application doesn’t see my paying card. When I had the Marshmallow version of Android I discovered that when I stopped the Knox application, It started working properly. After installing Android Nougat, stopping Knox isn’t enough. I don’t know which process should I stop my paying card to be visible by the application.. — Piotr

Solution: Hi Piotr. If this problem started after you installed Android Nougat, make sure that you clear the cache partition first. This will force the phone to delete the existing system cache and create a new one. Sometimes, updates may corrupt the system cache and clearing the cache partition is the easy fix. 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 wiping the cache partition won’t fix the problem, the next step that you must do is to clear the cache and data of NFC contactless app you’re using. 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 6.0.
  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.

If both procedures won’t help fix the problem, wipe the phone via factory reset. This procedure, together with wiping of the cache partition, is a must-do in fixing issues following a system update. Make sure that you create a backup of your files before doing it.

To factory reset your Galaxy S7 edge, follow these steps:

  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 #3: Galaxy S7 Google app and email keep crashing

Anytime I go to use any Google App, shortly after starting them they stop. Even my emails. It started three days ago. I have virus protection and I always stop my running apps. Boost my phone cool it down and have clear Web history temp files, etc. All my apps are up to date. Checked to see if phone is up to date, and it is. Can’t take the battery out. I’ve been temporarily fixing app by pushing down the volume button as a temporary reboot. I don’t know what else to do at this point. I have insurance on it I pay monthly for. There’s very little minimum Ware on my phone. I’ve only had it for 2 months. — Rachelkaminski3

Solution: Hi Rachelkaminski3. Did the problem start after installing a system or app update? If it did, try to uninstall the app you updated and observe the phone if it makes any difference.

If the issue started to appear after you installed an update for Android, make sure that you do the steps we suggest for Piotr above.

There’s a chance that the problem is being caused by a third party application so you can also boot the phone to safe mode. Safe mode prevents third party apps from loading so if your email and Google apps work fine, that’s proof that an app is to blame. Safe mode is not a solution in itself and won’t help in identifying the culprit. If you think an app is problematic, you must uninstall third party apps until the cause is removed. Be sure to observe the phone every time you remove an app so you’ll know if the issue has been fixed or not.

To restart 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.

Problem #4: Galaxy S7 Outlook and Gmail apps cannot send emails

I have Outlook App and Gmail App installed. I can successfully send/receive emails with my Yahoo account. We use Office 365 email server at work and I can receive emails from it. However I am unable to send emails to it from my S7 (both apps fail to send).

I have tried resetting the account, clearing cache, rebooting the phone, etc. In the Outlook App it shows email “Sent” but never shows up in the Outbox or Sent Folder. If I search for the email it shows as being in “Drafts” folder but is not actually viewable in that folder.

In the Gmail App a sent message shows in the Outbox folder first as “Queued,” then briefly as “Sent,” then “Failed.” Our IT Admin says all my settings are correct. And other employees are using S7 with these apps successfully.

Early on IT told me to disable the “Samsung” email app – that Gmail/Outlook is preferred. I see no way to “uninstall” the Samsung App but it is not set to default. This has been an issue since I purchased the phone back in November 2016.

Note too that I had to rep[lace the phone because of unrelated damage, so it is my second phone. My previous phone was an iPhone 5S which supported our business email with no problems. Any suggestions are appreciated. —  Jim

Solution: Hi Jim. We can’t see the logic of disabling the stock Samsung email app as a solution in this case but if you want to try it, go ahead. Samsung email app is coded with the original firmware so you can’t remove it. However, you can try to Force close it to revert it back to its default state.

You also want to try factory reset in this case because there’s very little hint that we can use to identify the problem. Once you’ve done a factory reset, configure your email to the Gmail app before installing other apps and updates. If the issue persists, it’s possible that your email may not support Samsung’s email system or app. You must work with your IT department to identify the cause of the problem.

Problem #5: Galaxy S7 edge audio randomly go away

Hi there. My Galaxy S7 edge (and my boyfriend’s) both have come upon the same issues within just 2 days of each other. Our S7s’ sound will just randomly go away. It won’t make any sounds (except mine makes the bloop noise when i hit the volume up button to confirm the sounds all the way up). But it will work again after a restart. For a while. Mine quit for the 1st time sometime last night and made me late for work. Restarted it when i got to work and it worked fine until about 15 mins ago (almost 8 hours after the restart.) What do you think is the issue? Our phones ran software updates a couple of weeks ago. And I’m not sure but i think it’s the Marshmallow i have currently. — Lauren

Solution: Hi Lauren. If both phones are of same exact model from the same carrier, this problem may be due to poor coding of the firmware. Be sure to report the problem to your carrier so they can do something about it.

If you have different phone models or carriers, try to do the basic software troubleshooting such as wiping the cache partition and factory reset.

It’s also possible that you may have installed the same app that causes a conflict with the operating system so try to boot your phone to safe mode and observe how it works.

Problem #6: Galaxy S7 only detects few GBs in an SD card

When I got the phone a few weeks ago, i put my SD card in it and began to download music from my Google Play as I always do. It was a 64 GB chip but would say it was full when there was 12 GB left of space. I assumed it was standard for that to happen and I needed a bigger card. Yesterday I got a 128GB, formatted it and began to again load music on it. After about 12 GB it stopped and the card was no longer mounted apparently. I took the card out and put it into an old Samsung and reformatted it. Placed it back in S7 and it was recognized, began again with similar result.

I have 3 different cards and tried them all, if it even saw the card it would only again load just a few GB. Why is this happening and is there a solution? Thanks. — Kimbrie

Solution: Hi Kimbrie. There may be a software bug causing it to read SD cards incorrectly. To try to fix it, make sure that you do a factory reset so you can eliminate potential bugs and possible third party app or service that may be causing the trouble. Here’s how:

  • From the Home screen, tap the Apps icon.
  • Find and tap Settings and then touch Backup and reset.
  • Tap Factory data reset and touch Reset device.
  • If you have screen lock feature turned on, enter your password or PIN.
  • Touch Continue.
  • Tap Delete all to confirm your action.
  • Once the device has been reset, insert the SD card again and see if it fixes the problem. Be sure not to install anything during the observation period.

If the problem remains after a factory reset, consider sending the phone in for replacement.

NOTE: Factory reset will erase all user data so make sure that all irreplaceable files like photos, videos, contacts, etc. are backed up.

Problem #7: Galaxy S7 won’t connect to a specific wifi network

Hi! I have a Samsung Galaxy S7. I have never had issues with wifi connections until January of this year. It connects automatically to my home wi-fi with no problems. It used to connect to my church’s wi-fi automatically with no problems, until this year in January. Now, this particular wi-fi network will not connect. My husband’s phone (Galaxy S6) connects to this network with no problems, along with many other people with a variety of phones.

I have tried all the “fixes” suggested on the web (aside from a reset) since I connect at home with no problems. I can’t change any of the advanced settings as it doesn’t give me the option to switch from DHCP to static. It shows me the option but if I select static it grays out the connect button so I can’t select it.

I have tried turning off mobile data and wifi and then turning wifi back on, to no avail. I have attempted turning all off, turning on airplane mode and trying wifi, no avail. I have repeatedly restarted my phone.

Pretty much if there was a suggestion online that didn’t sound like it would break my phone, I tried it. 🙂 Help? I appreciate it!!        — Karla

Solution: Hi Karla. There can be a number of reasons why a phone may fail to connect to a wifi network so we will discuss some of the common ones here.

Wifi feature bug. Inefficient coding can affect even basic phone functionalities like wifi. In most cases, coding-related issues are beyond an average user’s ability to fix but in your situation, you can try to disconnect and reconnect from the network first and take appropriate steps afterwards. Simply tap the network and click on “Forget” to disconnect. After that, restart the phone, then connect to the same network again.

Wifi admin is blocking access. If other phones are connecting to the same wifi fine while yours is not, you should consider asking help from the administrator of the network. There may be an IP conflict going on, or that your device is simply not authorized to connect for some reason. Some routers may also limit the number of active devices connecting at the same time and will block any further connection until there’s a slot is made available. Whatever the case may be, you should talk to wifi administrator if you want to get to the bottom of the problem.

A third party app may be blocking connection. To see if there’s an app causing this problem, boot your phone to safe mode and observe when you try to connect to this wifi network. Make sure that you restart to safe mode before attempting to connect. Here’s how to restart 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.

Remember, if you’re able to connect to this wifi network while in safe mode, that’s proof that an app is to blame.

Factory reset. If nothing changes after doing our suggestions above, the issue must be software-related. Do a factory reset to fix the problem.

Problem #1:  Galaxy S5 mobile data not working in the UK | Roaming on Galaxy S5 not working

Hi. I bought a Samsung Galaxy S5 Neo from Romania locked on carrier Orange. I unlocked it at a GSM store, and went to UK. I bought an O2 pay to go SIM card. After the settings came in, i installed them, and after like 5 minutes I could call and text, but no SIM internet was available. it worked for like 2 minutes, but then the 4G symbol disappeared. I went to the O2 shop. they tried to put the APN settings again, it didn’t worked. they tried on the computer different things they said that was the most they can do. they tried my SIM in another phone to see if the SIM was faulty but it was Ok. so my problem has to be my phone. I got the 6.0.1 version, baseband version G903FXXU1BPD4, KERNEL VERSION 3.10.61-8140803, I came back to Romania and tried the roaming internet, the 4G symbol appeared but I don’t have roaming internet sadly, so please help me for when I go back and that is soon. and also in my country the SIM internet is working of course. Thank you !!! — Andrei

Solution: Hi Andrei. There are a number of reasons why mobile data won’t work so you must check the following:

  • Network type. While mobile data may work on 2G, the speed is terribly slow and won’t even manage to open a decent website. You must either have a 3G or 4G coverage in the area in order for you to use mobile data comfortably. If your phone does not detect 3G or 4G in the  UK, it may suggest that:
    • 3G or 4G in your area (in the UK) is terrible or non-existent,
    • your phone is not permitted to use O2’s mobile data service
    • your phone’s hardware does not support O2’s frequency bands
  • APN settings. If:
    • O2 store representatives have set the APN settings correctly,
    • the phone is permitted to use O2’s mobile data service, and
    • your phone’s hardware is compatible with O2’s frequency bands,

then there’s no reason why mobile data won’t work. Assuming your phone’s mobile data function is working, one of these necessary items above must be missing, preventing your phone from connecting to mobile data.

To check if there’s a provisioning issue, contact O2’s customer support for help.

For your roaming issue in Romania, make sure that you contact your wireless service (the company of the SIM card you’re using). Roaming problems can involve possible reasons that may be specific to a wireless carrier so they are the only party that can effectively help you.

Some of the questions you should consider when dealing with roaming issues are the following:

  • Did you set roaming up before leaving for Romania? This involves help from your wireless carrier. You need to activate roaming service with them first in order for you to use your phone outside your country or network.
  • Is airplane mode on?
  • Is roaming permitted in your specific place in Romania? This question can be answered by your carrier. In order for roaming service to work, your carrier must have an agreement with other carriers to allow their customers to continue using their mobile services. You must talk to your original carrier about this.
  • Is your S5 set to automatically select a network? If you’ve already determined that roaming has been activated for your phone, try to manually search for a network by following the steps above:
    • From the home screen, tap and drag the Notifications bar downwards.
    • Tap the Settings icon.
    • Scroll to and tap More networks.
    • Tap Mobile networks.
    • Tap Network operators.
    • If prompted tap OK.
    • Tap the required network.
  • Are you getting 3G or 4G coverage? As mentioned above, your phone must be able to connect to either 3G or 4G network to have a good mobile data service. Of course, that can only happen if your phone’s hardware supports the frequency bands of the network. If the phone isn’t compatible, there’s no amount of troubleshooting that you can do to solve your problem.

If all these items have been covered but mobile data continues to fail, contact your carrier for additional support.

Problem #2: Galaxy S5 can’t read an SD card

Hello. I discovered your site while trying to research a new issue that popped up on my phone. Two days ago, my phone unexpectedly stopped reading or even recognizing my SD card. I’ve done all of the various normal troubleshooting that has been suggested in the various forums and sites, but nothing has fixed it. I did insert a different SD card and the phone recognized it and I was able to view pictures from that card. so it’s likely that the current SD card has just gone bad (which is a bummer as I had no backups of years of photos). But what’s really puzzling to me, is that when I go into Settings/System/Storage, I see nothing about External storage at all. Even with the SD card removed and powering up the phone and going to the Storage utility, there is nothing about an SD card or external storage. Everything I’ve read or seen tells me this is the location where I’m going to see options to mount or unmount a SD card, but all that is visible to me is the Internal Storage statistics. Am I missing something entirely? — Kevin

Solution: Hi Kevin. If we are not mistaken, you’re wondering why you’re not getting the options to mount or unmount an SD card when the SD card is not inserted in the phone. The said options are only available if your phone detects that there’s an SD card inserted in the first place. Mount or unmount options will not be available under Settings>Storage if:

  • the phone is unable to detect an SD card because of a bad SD card slot,
  • there’s no inserted SD card,
  • the inserted SD card is corrupted/unreadable

Since your phone is detecting a second SD card without problems, that’s a clear indicator that the problem only lies on the first SD card. You must reformat it if you plan on using that card again. Before you try to reformat it though, make sure that you try to see if another device can still read it so you can save your files. If there’s no other device that can detect it, forget about files — they’re good as gone.

Problem #3: Galaxy S5 keeps losing network signal

Hello. I purchased an S5 on eBay and thought all was good but then I noticed I was losing my network connection often. It happens at any moment but I will lose all bars and there will be no 3G or 4G icon, all will be empty. If I want to make a call or check my voice mail, it will state that my phone has lost connection and give me the option to activate wifi calling. I have noticed that I will lose connectivity easily when going into buildings, everyone else is talking on their phones, mine won’t have a connection. I am with Verizon and my wife’s phone will work fine (also with Verizon). When on a call it will always drop out for a few seconds and then come back in usually within the first minute of the call. I have noticed that when I lose the connection, I can switch airplane mode on, then off again, and it will usually reset the connection. It has become very problematic. Any ideas? — Jake_ruh

Solution: Hi Jake_ruh. An issue like this is most often due to bad hardware. To check, you must try all relevant software troubleshooting. Below are the things that you can try.

Wipe the cache partition. You want to make sure that your phone uses an updated system cache. Sometimes, app installations or system updates can corrupt the system cache. Wiping the cache partition will ensure that the device’s system cache is up-to-date. To do that, follow these steps:

  • Turn off your Samsung Galaxy S5 completely.
  • Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  • Keep the three buttons pressed and when ‘Samsung Galaxy S5’ shows, release the Power key but continue holding the other two.
  • Once the Android logo shows, release both the Volume Up and Home buttons.
  • The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  • Use the Volume Down key to highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  • The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Observe in safe mode. If wiping the cache partition won’t improve the situation, the next step for you is to see if one of the third party apps is to blame. This is done by restarting the phone in safe mode. While this mode is active, all third party apps and services will be blocked. See to it that you observe the phone for a few days while in this mode so you’ll notice the difference. Remember, if the problem won’t occur while safe mode is enabled, that a confirmation that our hunch about a third party app causing the problem is correct. To boot your S5 in safe mode, follow these steps:

  • Turn off the phone completely.
  • Press and hold the Power key.
  • Once ‘Samsung Galaxy S5’ shows, release the Power key and immediately press and hold the Volume Down button.
  • The phone will restart but keep the Volume Down button pressed.
  • Once the phone has finished restarting, ‘Safe mode’ will be display in the lower-left corner of the screen.
  • You may now release the Volume Down button.
  • Observe the phone for a few days.

Wipe the phone via factory reset. Finally, the last thing that you can do on your end is to restore all software settings back to their known, working state. Also known as master reset, factory reset will not only eliminate existing software bugs but will also wipe the phone’s internal storage. Try to avoid installing apps right after you factory reset your S5 so you can observe how it works. Let it run for a day without third party apps so you’ll know if there’s a difference as far as its network function is concerned. The only other important thing that you want to do right after a factory reset is to install system updates (if they are available). Doing so will update both the operating system as well as the baseband version (the operating system your phone’s modem needs to work properly).

If the problem stays though, that’s proof that hardware is to blame. You must then find a way to have the phone replaced.

To factory reset your device, follow these steps:

  • Turn off your Samsung Galaxy Note 5 completely.
  • Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  • Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  • Once the Android logo shows, release both the Volume Up and Home buttons.
  • The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  • Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  • When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  • The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Problem #4: Galaxy S5 screen keeps flickering and won’t sometimes respond

Hey there. I have a problem with my Samsung Galaxy S5. It always keeps flickering and sometimes it doesn’t respond even if the brightness was set to high. When I try to turn on my phone every morning I just keep pressing both the home button and the power button hoping that it will respond. It takes like 3 minutes to open my phone because it does not respond and it gives me a black screen with some flickering green and white colors. I tried to reset my phone, go back to a lower version (I have 6.0.1 right now). And I tried a lot of other things I had found in the internet the last months. But nothing worked Can you please help me fixing my phone? Thank you. — Khalid

Solution: Hi Khalid. Android troubleshooting is simple — if you’ve already exhausted all software troubleshooting, then bad hardware must be the cause. In majority of cases, flickering screen issue is due to a malfunctioning screen assembly. Try to boot the phone to other modes to see if the screen flickering issue will be absent. If the problem stays in all of the alternate modes, that’s proof that you have a hardware issue. You must have the phone repaired.

Boot in Recovery mode:

  • Charge the phone for at least 30 minutes.
  • 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.’
  • You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume DOWN 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 DOWN keys.
  • Wait until the Download screen appears.
  • 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.
  • Use Google to look for a guide on how to do it.

Boot in safe mode:

  • Charge the phone for at least 30 minutes.
  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  • 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 #5: Galaxy S5 cellular network signal keeps dropping

When trying to make an outbound call my signal drops from 4G to 3G, 2G then H and finally E. And although the timer starts to say I’m connected, they cannot hear me and I cannot hear them. Is it a coincidence that my 2-year contract is due soon or is it that the problem started soon after I updated my OS to 6.0.1? My wife has the same phone but hasn’t done the update and doesn’t seem to have problems. I’ve done a soft reset but still have the problem and I’m one step away from backing up my phone and doing a full factory reset but really want to know if it will cure the problem. I love the handset and would go SIM only when my contract comes to an end. — Adrian

Solution: Hi Adrian. If the issue started occurring after installing an update, then wiping the cache partition and factory reset should help you. Refer to the steps above on how to do these solutions.

Also, make sure that you only install back after a factory reset apps that are compatible with Android Marshmallow. This may sound simple but updating apps and making sure that you only install compatible apps are often overlooked by many Android users after a system update. Keep in mind that not all apps are created equal. One app may work well with Android Lollipop but not with Marshmallow. It’s your responsibility to keep your apps updated and compatible. To check if an app will work with your operating system, consult its installation page in Google Play Store. Better still, try to contact the developer to get firsthand information.
