Galaxy S7 Edge reboots on its own shortly after being updated to Nougat

Problem: My phone is an S7 Edge. There was this update I downloaded a couple of days ago and I think it was what they call Nougat or something. I’m not really sure if the download was successful or if the new OS got installed successfully. But now, my phone keeps rebooting on its own every so often that I could no longer use it properly. I was composing a text message and the phone reboot. This happened a few times already and it’s a waste of time not to mention very annoying. Can you help me?

Troubleshooting: The new firmware may have been installed successfully but since it’s a major update, some caches or system data may have been corrupted and those were the ones that cause this problem. There are a couple of procedures I want you to try and if the problem still occurs after that, you should bring your phone to a tech to have the firmware reinstalled.

Step 1: Delete the system caches so they’ll be replaced with new ones

The following procedure is safe for your files and data. You don’t have to make a backup at this point. It is also very effective in fixing issues like this that occur after a firmware update.

  1. Turn off the phone.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 Edge 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 wiping the cache partition. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Continue using your phone after this to see if it still reboots on its own and if so, then move on to the next step.

Step 2: Perform the Master reset and continue observing your phone

A reset will delete all your personal files and data so if possible, backup ones you don’t want to lose. Also, make sure you disable the anti-theft feature of your phone so you won’t be locked out of your device after the reset.

This is how you disable the anti-theft security feature…

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

And this is how you reset your device…

  1. Turn off your Samsung Galaxy S7 Edge.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key. NOTE: It doesn’t matter how long you press and hold the Home and Volume Up keys, it won’t affect the phone but by the time you press and hold the Power key, that’s when the phone starts to respond.
  3. When the Samsung Galaxy S7 Edge 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. NOTE: The “Installing system update” message may show on the screen for several seconds before displaying the Android system recovery menu. This is just the first phase of the entire process.
  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.

If the problem still occurs after this, then have the tech take care of the problem for you.

Galaxy S7 Edge keeps rebooting even if it’s in Safe mode

Problem: I have this reboot issue for S7 edge. When I got into safe mode, the phone still reboot itself. I did not try the factory setting, because I do not want to loss the date on my phone. Any advice prior to factory reset, if there is a chance that I can get date out.

Thanks

Solution: Since, the issue occurs even if it is in safe mode, then probably, it is the firmware that has an issue. In fact, lots of factors to be considered that the firmware could not function normally. It could be the system caches were outdated or the firmware itself was corrupted especially if you do an update on your phone. So, to determine what really caused the device to restart itself, here are the steps that you should do:

Step 1: Delete the system cache

In some cases, due to outdated or corrupted caches in the cache directory the firmware is having a hard time recognizing it and that may be the reason that the device cannot boot up or crash without apparent reason. In this method, the old caches stored in the cache directory  will be erased and replaced by newer caches. If that’s the case, then this procedure might fix it. Follow the same steps as above.

After deleting the system caches of the phone and the problem persists, then you don’t have a choice but to proceed to the next method.

Step 2: Perform master reset on your phone

This procedure is more complicated compared to the first method that you did on your phone wherein all your data and files will be deleted. But the good thing is, if it is the firmware of your device caused the problem, then there is a big chance that the problem will be fixed. But before doing so, make sure to create a backup including your contacts, photos, videos and music because all will be erased. Follow these steps:

  1. From any Home screen, tap the Apps icon.
  2. Tap Settings.
  3. Tap Cloud and accounts.
  4. Tap Backup and reset.
  5. If desired, tap Back up my data to move the slider to ON or OFF.
  6. If desired, tap Restore to move the slider to ON or OFF.
  7. Tap the back key twice to return to the Settings menu, then tap General Management.
  8. Tap Reset.
  9. Tap Factory data reset.
  10. Tap Reset device.
  11. If you have screen lock turned on, enter your PIN or password.
  12. Tap Continue.
  13. Tap Delete all.

Galaxy S7 Edge screen keeps flickering

Problem: My Galaxy S7 Edge screen ‘blinks’. It just started about 1 week ago. I have not installed any new programs. I have not dropped it or gotten it wet. While I am looking at the screen, it appears that it is closing whatever you are reading and brings it back immediately. It does not flicker or change color. It does this about every 1-3 minutes. It’s as the phone blinks. Thanks, Brenda.

Solution: If you are certain that your phone doesn’t have hardware issue, then may be it is a firmware related problem. Now, the first thing that you should do is to boot your phone in safe mode to determine if one of your downloaded applications triggered it. Remember that this method is only an android environment in which, all third-party apps will be stopped from running and only the pre-installed will run in the system. Here are the steps to boot the device in safe mode:

  1. Press and hold the Power key.
  2. When Samsung Galaxy S7 Edge logo appears, release the Power key and immediately hold the volume down key.
  3. Continue holding the Volume Down key until it finishes its rebooting.
  4. When “Safe mode” appears on the screen immediately release the Volume Down key.

However, while in safe mode and the screen still flickers, then it might be the firmware that has the problem. The next thing that you should be doing on your phone is to delete the cache partition of the phone. The purpose of doing this is to make sure that the caches in the system are all new and could run properly once you perform a task on your phone. But if clearing the cache partition could not fix the problem, you can perform the last method by resetting the device.
