Problem #1: Galaxy S7 Edge keyboard lag issue | Delay in sending and receiving SMS on Galaxy S7 Edge

Hi. My wife and I have started using Samsung Galaxy S7 Edge cellphones since 3 weeks ago. We have to say that from day one text messaging is a real pain, whether we are the sender or the recipient. There are many big issues:

  1. The keyboard is very sticky every time we type in texts. So, we cannot type fast as we should be able to. And we have to wait until our message is successfully sent off to the system before we can start typing our next text. Chatting through text messaging is simply impossible.
  2. At least it takes 15 seconds or more after the ‘send’ button is pressed before our message can be sent to our Internet service provider’s server. In our case, it’s Telus Mobility’s.
  3. Then there is invariably a delay before the recipient can receive the message. A 4 to 5 minute delay is not unusual. Quite often, I sent my wife a text and it was not until 41 minutes later when she could receive the notification and the text message itself! The signal was, as shown on the phone screens, good. We were in mid-town Toronto but not in any remote areas. The delay is so unacceptable. We need to use texting to send urgent messages but it can no longer be relied upon. I have contacted Telus. They said we should bring the phones back to Samsung to see if there is a glitch issue. But interestingly, we do not have the above three problems at all when we use Whatsapp to do messaging! Please let me hear from you. Thank you. — Sai

Solution: Hi Sai. Whatsapp uses a third party server to handle your messages so if the above mentioned issues only occurs when using a specific application such as the native messaging app, the issue may lie on that app itself, or the network that manages your text messages. The first thing that you want to do is wipe the phone’s cache partition in order to refresh the system cache. Here’s how:

  • 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.

If refreshing the system cache won’t resolve the issues, make sure that you delete the cache and data of the apps in question. Kindly follow the steps below:

  • 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.

Should there be no change after performing these two procedures, bring the phone to your carrier so they can check if it’s a unit problem or something related to their network services in your area.

Problem #2: How to unlock a Galaxy S7 from Saudi Arabia

Good day. I bought a Samsung Galaxy in Saudi Arabia about a month ago. I didn’t noticed that this phone can only be used here in Middle East & North Africa. It’s a SIM only based in the sticker outside the box. I browsed on the web how to unlock this phone without deleting my files saved in this phone. Did you hear about theunlockingcompany in the web? Is that legit? Or what should i do to unlock this phone.

By the way, I’m from Philippines and i will send this phone to my home country that’s why i want to unlock this before i send it home. Thank you so much in advance… — Ecarpena79

Solution: Hi Ecarpena. There are two common network technology being used around the world — GSM and CDMA. The former needs a SIM card in order to store subscriber and some network-related information, while the former stores the same type of information directly into the phone’s memory in itself. CDMA phones nowadays also sport a SIM card slot in order to use 4G and/or LTE technology but all subscriber information must be programmed into the phone itself and not stored in the SIM card. In other words, CDMA phones only uses the SIM card so it will be able to use LTE network while GSM phones uses the SIM card to keep the user’s identity and other important network details.

If your Galaxy S7 is a GSM phone, then the only things that you want to check these two things:

  1. Its frequency compatibility with networks in the Philippines, and
  2. that it’s network unlocked

The first one requires that your phone’s hardware is equipped to work with radio frequencies (or band) networks in the Philippines are using. Not all GSM phones are capable of working with the usual bands carriers are using so you must check this first. This means that even if you are in a GSM network in Saudi Arabia right now, there’s still a chance that it’s operating frequency may be different from your carriers in the Philippines. You did not provide the model number of your device so we can’t do a quick check about its operating frequency bands. You must do some digging online to do that yourself. Perhaps this Samsung page can get you started. Make sure that you use the correct the model number of your device when looking for information about its network specifications. Once you have the correct specifications of your phone, be sure to check if they are compatible with the operating frequency bands of carriers in the Philippines.

Frequency compatibility is determined by the available hardware in your phone. This means that if, for example, your Philippine carrier is only operating LTE in frequency bands 4 and 6 while your phone only works in bands 3 and 7, you will be unable to use LTE there. Since this is hardware incompatibility, there’s nothing that you can do to fix it and there’s no software hack that can change the situation. Don’t worry though as most GSM networks in Asia and Middle East usually operates in compatible multiple frequency bands so there’s a huge chance that your device will not encounter network issues in your home country. Still, we strongly suggest that you do basic research before pushing with your plan to avoid disappointing yourself.

Now, the second point is relatively easy to resolve. There are many shops, not to mention online ones, in almost every country that can unlock a GSM phone. We recommend though that you before you bring or send the phone to the Philippines, you ask one of your relatives or friends if there’s a shop in your location that can network unlock the particular model of your phone. Again, doing this in advance means saving yourself from disappointment.

We are not in the business of unlocking phones so we are not familiar with theunlockingcompany and their services. A quick search in Google provides some basic information about this online company but we still advise you to be wary, especially when providing credit card information or any payment. We don’t usually recommend going online when it comes to this job but if you can’t find any reliable shop in Saudi Arabia to do the job for you, then going online may be your only choice. Again, we don’t know of any online service that can unlock the particular model of your phone so it’s up to you if you want to take risks.

Problem #3: Galaxy S7 not fast charging anymore

About a 3 months ago my S7 won’t want to fast charge anymore. Started charging without fast charge. Then it started charging slower and slower. I only use Samsung charging cords. I bought a new charger. It started fast charging again however the same events occurred again. Since it charges so slow like 8 plus hrs to get to 100%, I’ve been leaving it overnight to charge. I woke up and it was at 0%. I restarted it and it took 9hrs to get to 75% and now its freezing and working slow too. I have tried restarting it in the past three times in a row and nothing. I’m afraid i might infected my phone by surfing porn. Not sure if I’m right but i need help getting it back to normal. — Sonia

Solution: Hi Sonia. The first step that you want to do is to see if one of your apps is to blame. Boot the phone in safe mode and see if there’s a difference. While in this mode, no third party app will be allowed to run. If one of your apps is the cause, the issue should not occur. To boot your phone in safe mode, follow these steps:

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

If nothing changes while the phone is in safe mode, consider wiping everything via factory reset. To do that, follow these steps:

  • Turn off your Samsung Galaxy S6 Edge.
  • Press and hold the Volume Up, Home and Power keys together.
  • When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  • Wait until the Android Recovery Screen appears after about 30 seconds.
  • Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  • 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.
  • After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.
  • Once the reset is complete, observe the phone for a day without installing any of your apps. If your phone charging behavior won’t change during the observation period, you can bet a hardware malfunction is causing the issue. Find a way to have it replaced.

Problem #4: Galaxy S7 is completely dead

I woke up and my phone’s dead. I attempted to put it on charge from 4 different chargers but it’s not acknowledging the charger. So I try to turn it on and it comes on with 50% battery randomly and then the battery starts dying, also saying my phones overheating. But my phone’s been off for 10 hours and was cold as ice.

Whilst I’m trying to call my mobile provider so I could reboot or get any instructions on how to fix the problem the battery dies. Now the phone won’t charge at all. It does switch on to tell me 0% then it switches back off. It’s been off for 24hrs. tried it today but it’s still not responding to charger so wtf. This is a Samsung issue as much as you want to say this is a batch issue. when i first got my phone it doid something similar. it wouldn’t switch on or charge. I took it to Samsung and Samsung said it was their fault due to some software issue that the company was having. He said another software update would be installed to prevent this from happening but clearly it didn’t work. I’ve had my phone for awhile and now it just randomly doing this. No red charger light appears, no battery symbol. I need to information on my phone before any reset so how do we do this? — Tantrumartist

Solution: Hi Tantrumartist. If your phone is totally unresponsive, there’s very little to nothing that you can do on your end. Try to check if you can boot it to other modes as detailed below:

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.

You can also try to boot in safe mode (steps provided above). If  all three button combinations won’t work, contact Samsung or your carrier for a phone replacement.

Problem #5: Galaxy S7 keeps dropping network connection

I have a Samsung Galaxy S7 through Sprint and for about a month now I have been losing network connectivity. The triangle at the top, where it usually says either 3G or LTE and then the triangle is “filled” to show how good your connection is, is completely empty with no letters next to it. Someone from Sprint told me that that meant roaming, but that is not what it means. When it is roaming there is an R and an “!” on the triangle. This usually happens at work but has happened at home. I have worked in this building for over a year and a half and have lived in my house for longer than I’ve had Sprint. I have never had problems before a month or so ago.

This started happening before a system update (and actually I have had 2 system updates since it started happening) and that didn’t fix the problem. Rebooting DOES fix the issue, but I’m getting sick of rebooting my phone 4-5 times a day. I have also been in contact with Sprint 3 times about this issue. The problem, though, is that I do what they tell me and reboot and it’s fixed and I won’t know if the issue is still there until the next day when I’m back at work.

Here is some (if not all, it’s hard to remember) of what I have done to try to solve this issue:

  • set Network mode to Automatic when that didn’t work set it to LTE/CDMA that didn’t work so it’s back at Automatic
  • I updated the Profile
  • I updated the PRL.
  • There have been 2 separate software updates
  • I wiped the cache partition. there was something that technical support had me do by dialing on my keypad some code that starts with a #, but I can’t remember the code.
  • I REALLY don’t want to do a factory reset… PLEASE tell me something else that I can try!!! — Chris

Solution: Hi Chris. The cause of the problem can be anything at this point so you really have to do all software troubleshooting, which includes factory reset, in order to isolate the it. Performing a factory reset might help in this case, especially if it’s just a firmware bug. If nothing works after a factory reset though, try to ask Sprint for a replacement phone so you will know if the current one is experiencing a hardware malfunction.

Problem #6: Galaxy S7 keeps dropping Wi-Fi connection | Galaxy S7 keeps rebooting on its own

Firstly, my Wi-Fi signal on my phone drops off constantly and I have to reconnect frequently. Have tried turning off modem for some time. Also have forget connecting to network and input the password.

Secondly, my phone keeps restarting when I take a picture or get a phone call or just generally many times in the day for no reason.

Thirdly, I charge the phone but seems to take longer now to charge the battery and also the battery loses power so quickly even though I shut down apps. Or it may still be showing about 20% and then turns off. I connect to a wall charger and is showing 0% please can you help. Thanks — Sodedra

Solution: Hi Sodedra. For your first concern, try to isolate first if the issue is on the phone or on the Wi-Fi network. Get a second smartphone or device, connect it to your Wi-Fi, and observe if the same problem happens. If it does, contact your internet service provider so they can help you fix your Wi-Fi. However, if the second device won’t show the problem you’re experiencing on your S7, then the issue is clearly isolated to your phone only. To help you fix the problem, try wiping the cache partition, boot the phone in safe mode, or perform a factory reset.

For the second issue, the same set of software troubleshooting can be done.

Finally, if the third issue won’t be resolved by doing the software troubleshooting steps, try using a different Samsung charger to see any difference. If the problem remains, the phone’s charging port or some hardware components that manages power consumption may be to blame. Find a way to have the phone replaced.

Problem #1: Can’t access camera settings menu after Galaxy S7 installed an update

Hi. I am having a problem with my camera settings menu. This is for a Galaxy S7 which I purchased in May 2016. Something updated on the phone — I don’t remember what might have happened before this issue — and then I noticed my camera was making the click sound when I took a picture; this is an option which I had turned off when I got the phone. So I tried to adjust the settings and there is a problem. When I click the gear icon, the settings window pops up for 1 second and then disappears (it goes back to the camera mode). I have tried clearing my data and cache, a soft restart, rebooting in safe mode, and using Advanced Task Killer. I really don’t want to have to reset to factory settings or send it in for service for just this. Can you help? Also, if I do have to back up the phone using Smart Switch (before doing one of these more severe steps), I’m not clear on what I’m supposed to select from this website in order to back up the phone to my computer: https://www.samsung.com/us/smart-switch/ Thank you. — Melissa

Solution: Hi Melissa. There are 2 necessary things that you must do if you notice problems after an update — wiping the cache partition and performing a factory reset.

Wipe the cache partition

The first one is intended to ensure that the phone refreshes the system cache, an important set of temporary files needed to load apps quickly. Sometimes, updates can make existing system cache corrupt or outdated. To minimize potential bugs, make sure that the system cache is fresh. Here’s how to do that:

  • 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.

Factory reset

The other solution that you should try is factory reset. We don’t know what other software troubleshooting solutions you’re expecting but factory reset should be one of them. Doing so will ensure that your phone runs a clean firmware as well as restore all software settings back to a known working configuration. There’s no set of software tweaks specially tailored for a camera issue you’re describing here. You either do factory reset or not.

Smart Switch

This page gives a short description of available smartswitch versions depending on the gadget you’re moving your files to. At the bottom part of the page, there are clear explanations on which version to use — Smart Switch Mobile, Smart Switch for PC or Mac, and For other devices, use the Kies app. If you’re planning on transferring your files to a computer, then select one of the two available options under Smart Switch for PC or Mac. Once you click on the link, your computer should start downloading the installation files. Simply follow the instructions once the program has been installed.

Problem #2: Galaxy S7 is unresponsive

Hiya, I’ve owned my S7 for about 6 months now, and the issues arose about 5 months ago. Until now, I’ve been following the instructions I found on this site, which have been extremely helpful. As time passed, however, my phone has only gotten worse. My phone freezes, crashes, and reboots in a vicious loop so frequently that I’m lucky if I use my phone for 20 minutes without a crash occurring. If I’m unlucky it won’t make it to the lockscreen before crashing again. Sometimes a reboot will reset my system preferences. And last night, the phone has become completely unresponsive. Holding down the POWER and VOLUME DOWN buttons won’t work anymore and it won’t turn off either. The Samsung Galaxy S7 starting screen had a glitchy and pixel-ly purple line striking it. If you can, please help! I’m afraid I’m at my wits end. -Lisa (P.S. I don’t recall what my android version is, and I wish I could check what it is) — Lisa

Solution: Hi Lisa. If you’ve been having intermittent problem for months now, you should not wait until the warranty has expired before calling Samsung or your carrier to demand for a replacement.

Also, if your phone has become totally unresponsive now, then there’s nothing much than we can do for you. Try doing a hardware button combination to boot the phone in a different boot mode like Recovery mode, download mode, or safe mode. Below are the steps on how to do each of them.

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 logo 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.
  • 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 logo 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 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.

Contact Samsung or your carrier

As mentioned, if nothing changes after you try all the hardware button combinations, then your only resolution lies on getting a replacement. Call Samsung or any relevant party for unit replacement.

Problem #3: Galaxy S7 bootloop issue

Hello, I have had a Galaxy S7 for 2.5 months, and about a month ago the screen froze on me and I could not power it off. I ended up holding the Power and Volume Down keys to get it to reboot, and then it got stuck in a reboot cycle. I got it running again, but then the same thing happened and the next time I believe it was frozen on the Samsung Galaxy S7 startup screen. Since then I have tried: Master/ Factory reset…problem persists. Factory Reset without loading any 3rd party apps…was good for about a week, then problem came back. Booted phone in Safe Mode (following your instructions)…problem persists. Deleted system cache (following your troubleshooting instructions)…problem persists. According to your troubleshooting instructions, I should now take this in to my provider to have it repaired. What should I do or tell them to ensure that the repair shop doesn’t just do a factory reset and after a couple of days say that everything is fine and send it back to me without the actual problem being resolved? When I tried to drop it off for repair previously, the provider has told me that it’s likely a problem with my apps or a corrupt file, but I believe that booting it in safe mode disproves that theory? Any help or advice you can give me would be appreciated. — Diane

Solution: Hi Diane. Phone technicians are like medical doctors; they need as much input from the user in order to diagnose the issue. So our advise when bringing the phone to them the second time around is to give them the full history of your device, including obvious causes for hardware malfunction like water exposure, heat exposure, or times it fell. Technicians need some basic information to give them an idea where to start looking for the trouble. For example, if you dropped the device prior to the issue started occurring, you should mention it so they can check common vulnerable solder joints first.

And by the way, if your device is only a couple months old, we highly recommend that you go for a replacement from Samsung instead. Keep in mind though that Samsung will only honor the replacement warranty if there’s no sign of misuse, like a visible scratch, tampering of software or hardware, or water damage.

Problem #4: Galaxy S7 keyboard lag issue when receiving and sending SMS

Hi. Every time I am texting, and am in the middle of typing a text message and I receive another text message, my phone’s keyboard lags and I am unable to type until the full message has been received with a notification. And then after my phone catches up, I am able to text again.

Also, after I send one text message and go to send another, my keyboard lags and stops working until the message has fully sent and then it catches up and I am able to text again. I know it is a small issue but it is really annoying and an inconvenience when texting. — Cole

Solution: Hi Cole. Make sure that you clear the cache and data of the messaging app you’re using. Here’s how it’s done:

  • 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 or 7.
  • Once in there, look for the application and tap it.
  • 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 Cache and Clear Data buttons for the application.

Problem #5: Galaxy S7 in China only showing EDGE network

I have bought a Samsung Galaxy S7 after I so tragically lost my S6 at the beach. I got the device from my home country Cyprus and I have moved to China. I got a SIM card with mobile data from China mobile but the internet speed is so slow. It is the lowest and I get the E signal everywhere, which hardly even works. I can’t even connect to my VPN most of the times.

Also, I can’t use the mobile data as a hotspot for my laptop. I have been to the store and they said that my device supports only up to 2G speed. The phone was not even locked when I bought it back home. The SIM card works ok but the internet is unbearable. Shall I change carrier? Or is there something I can download on my phone to speed things up? I am reallyyyy desperate here and would really appreciate your suggestion. I can’t bear thinking I got a mobile less than a month before which I can’t use it for anything… Thank you! — Marlen

Solution: Hi Marlen. There’s no app or software hack that can help improve mobile data speed if E (which represents Enhanced Data rates for GSM Evolution (or EDGE)) is the only signal your carrier is offering in your area. EDGE only supports a maximum theoritical speed of 217 kilobits per second, which means it’s hardly able to even load a webpage decently. If you want to have at least a workable mobile data for browsing so you can also use hotspot, you must be in an area with a good 3G network coverage. If your current carrier does not offer 3G in your location, find a carrier that does.

Problem #6: Water damaged Galaxy S7 keeps showing SIM card needs to be inserted | Galaxy S7 screen not working properly after phone got wet

About 3 days ago I had noticed my Samsung was telling me I needed to put a SIM card in my phone. Which confused me because I forgot that I could even take out the SIM card. I had taken the SIM card out and replaced in back in the slot. But it still kept telling me there was no SIM card in my phone. After a couple of hours I tried to unlock my phone and the screen started glitching and showing all sorts of colors. After my phone’s screen would remain all black, even though I could tell it was unlocked. I believed I had caused it to get water damage. Since it has been raining where I live tons recently and It may have gotten wet while I was outside. However, over the last 24 hours I have turned it off and left it in some rice over night and it is still glitching. It is not as bad as it was 3 days ago (since I am currently typing on it) but I can tell it is still not working properly. I really hope you can help me figure out some solutions I could do to fix my problem. Since I do really love this phone. Thank you for your time. — Zoei

Solution: Hi Zoei. Water damage can lead to all sort of problems. The persistent SIM card error you’re getting may be a sign that the SIM card slot has malfunctioned after getting wet. The same is true for the screen glitch. Bring the phone to a repair shop so a technician can check if the phone can still be saved or not. Our blog does not provide hardware diagnostics and solutions so there’s nothing much that we can help.

Problem #1: Galaxy Note 5 fails to start after installing a game

Hi. I have only owned my new Android Samsung Galaxy Note 5 for about 4-5 months. it never gets turned off and is usually charged each night while I sleep. The phone has now 100% stopped working and cannot be charged. Initially it showed 0% battery power but when it is being charged a little light no longer shows. This has all happened over the evening when my 7 year old daughter had installed more ‘games.’ She said it occurred when she started “watching for free”. This was probably just a kids game invitation (my guess). It has just died! I am really worried as this is my only phone. Why has this happened? Do you think the battery has been totally drained and I need to buy a new one or does the battery just need removing and replacing or is it worse? I look forward to your thoughts. Many thanks. — Jen

Solution: Hi Jen. A full hardware check is necessary to identify whether or not this is just a battery-gone-wrong issue, or if it’s another else. That said, the only thing that you can try on your end is to see if you can boot the device in other modes. If your Note 5 will boot to another mode, the issue is more likely a software-related issue and not in hardware. Below are the things that you can try:

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.

If you can’t turn the phone on to any of these modes, the most likely cause is hardware malfunction. Contact Samsung or your carrier so they can  a hardware check or replacement.

Problem #2: Galaxy Note 5 stuck in Note 5 logo screen after failed CF-Auto-Root procedure

Dear Sir: Good Day! I own a Samsung Galaxy Note 5 Duos (SM-N9208) upgraded to Marshmallow. I decided to root the device using CF-Auto-Root for the model and the appropriate version of Odin. The process ran smoothly and the application displayed “Pass”. However, when the device was restarting, it got stuck to the Galaxy Note 5 logo. I tried to do a factory reset but the device does not reboot to recovery mode, only download mode. I also tried to reflash the rooting files several times but without success. Presently the phone is not usable and freezes at the Samsung logo. Please advise me on this problem. I would appreciate your response on this matter. Looking forward to hearing from you soon. Thanks and Best Regards. — Lou Mari

Solution: Hi Lou Mari. The only effective solution to rooting-related issues is by doing a master reset. Supposedly, a successful root procedure will automatically prompt the device to Recovery mode, otherwise the use should boot to recovery manually. Since you are unable to do so, the rooting process may have corrupted the bootloader in some way, preventing the device to boot normally now.

Another good reason to mess up a device when rooting is when a user unintentionally uses an incorrect file. If you think you may have used a wrong file, try to unroot the device by flashing a stock firmware. Again, make sure that you use the correct stock firmware for this job.

Finally, the most common reason for issues encountered after rooting a device — locked bootloaders. Most carriers choose to prevent unofficial modifications to their devices’ software by locking the bootloader. If your phone’s bootloader has been locked and you tried to root it, that’s unfortunate as you just created an expensive paperweight. Contact your carrier and ask their policy towards software modification to know if your device may have a locked bootloader.

For possible solutions, we suggest that you contact the developer of CF-Auto-Root or visit their XDA-Developers forum. We haven’t tried using this root ourselves so we are not familiar with this product. We know that this root does not support all types of Samsung devices so make sure that you get direct information from the source of the code itself.

Problem #3: Galaxy Note 5 got damaged after installing software update from AT&T

I have a Note 5 and about 2 weeks ago they did an update for the software. I did it like other people have done. Then since that time my phone was really damaged. I just called AT&T to see if they can fix the problem but they can’t they told me. I have to buy a new phone, called couple times and there is no result.

I called Samsung but there’s no help. When I called AT&T, there is no help because there’s no insurance on my phone. so the only way is to throw away my phone and go buy a new phone and that’s ridiculous because my phone is still brand new. And then I don’t know I was searching online and I seen that you can fill out this to you guys and see you what you can do. Even though right now my phone it will be on 30% on my phone turns off and that’s ridiculous too because I have to put on the charge for another like 20 minutes to start using my phone and that problem starts since the software was updated so I need help please. — Susu

Solution: Hi Susu. Keep in mind that over-the-air (OTA) updates provided by carriers very seldom brick devices. In most cases where phones are rendered unusable after installing an OTA update, the most likely reason stems from the fact that the official software was modified. Software modification usually takes in the form of rooting, flashing non-official ROM, and even installation of third party apps from unreliable source. If your phone was never rooted, or its software remained official during the update installation, your best choice would be to ask direct assistance from your carrier. Since you’ve apparently tried to ask their support without much success, we suggest that you take a more drastic route of manually flashing a stock ROM. If you are not familiar with manual flashing procedure, use Google to find a good guide. The important thing to remember when flashing is to make sure that you use the correct firmware. Each phone model only works with a specific firmware so make sure that you find the correct one.

Problem #4: Galaxy Note 5 won’t turn back on

Hi. I own a Samsung Galaxy Note 5 and recently I have been facing these problems. Ever since 4 months ago, I had issues trying to turn on my phone. At times after turning it off it won’t power back on again. It got worse and the green Android robot would pop out and the left top corner would write: could not do normal boot .start udc download. Once I continue to restart my phone, I would be able to use it again. However, recently I could not power on my phone for 2 days straight. I charged it but it doesn’t on no matter how many times I restart it. I would like to know the reason why. — Eunicetay

Solution: Hi Eunicetay. There are a number of things that you should consider when dealing with this problem. The first one is app- or firmware-related reasons. Poorly coded apps or even operating system updates can sometimes lead to boot issues.

To check if an installed third party app may be causing the problem, try to boot your device in safe mode. If you will be able to power on the phone in this mode, make sure to observe it for at least 24 hours. If the problem won’t occur while safe mode is enabled, you can bet one of your apps is to blame. Uninstall apps until the issue is gone.

However, if the problem remains while safe mode is on, or if the phone won’t even boot to safe mode at all, try booting the phone to other modes. Refer to the steps provided above.

We’ve seen cases wherein the only reason why a device won’t boot up normally is due to a bad Power button. If you think the power button is bad, submit the phone for a repair so it can be fixed.

Problem #5: Galaxy Note 5 MMS fails when sending or receiving | Galaxy Note 5 keyboard lags when typing

When sending picture MMS from my phone I often get the error “server response error” and it fails. Also, I often can’t download the image that people send me. I try and try but nothing. I have done the resets and the 3 button starts but doesn’t seem to change anything. On the rare occasion it works.

Also I am often waiting for my phone to catch up to my typing. Have plenty of SD space and much room on my storage device. I don’t use many apps – only 3 pages. I type fast with 2 thumbs but I shouldn’t have to wait for it to catch up, should I ? I am eligible for upgrade – thinking of going to Iphone 7. What are your thoughts? A much better phone? I really don’t use. My phone for anything but email, phone messages pics etc in a real estate role. Thank you so much for your help. — Ray

Solution: Hi Ray. Our blog does provide device comparisons (which is better Android or iOS?) so if you want to know the strengths and weaknesses of different devices, please visit other blogs and forums.

Now, for your slow performance issue or slow keyboard response problem, the first thing that you want is to wipe the cache partition. Here’s how:

  • 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.

If the keyboard app remains laggy, do a factory reset and observe the phone for an hour before you install your apps. This will give you an idea whether or not the keyboard works fine when the firmware is fresh. Also, make sure that ALL (as in all) your apps are compatible with your operating system version. You can do so by simply updating them.

For your MMS issue, we strongly suggest that you let your carrier know of the problem, especially if it’s still happening even after a factory reset.

Problem #6: Galaxy Note 5 Wi-Fi not working

I was having the Wi-Fi greyed out issue after an Android update on my Note. I finally Googled it, which resulted in me realizing that another update was available that fixed the issue but since my phone was set to update on Wi-Fi only and I couldn’t connect to Wi-Fi…. you get the idea. So I did the update about a week ago and it seemed to fix the issue. Then last Saturday, I turned on tethering so my kids could watch a video in the car, and although it said tethering was working, their devices never registered (they couldn’t even see my phone). I turned it off but since then, the Wi-Fi button does not work again. I am considering moving on to another phone but I really love this one and I don’t want to get into another contract a week after finishing this one.. Anyone else experiencing this? — Tabi

Solution: Hi Tabi. We hope this is not a hardware issue. To check, try to perform a factory reset and like what we tell Ray above, make sure not to install your apps right away afterwards. Try to see how the Wi-Fi function works right after a factory reset so you’ll the difference. If nothing changes, you can bet hardware malfunction is to blame. In that case, you must find a way to have the phone replaced.

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

  • Create a backup of your files.
  • 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.
