Fixing Galaxy Note 10 that keeps rebooting on its own

I have personally experienced this problem before and just as I expected, it was just a firmware issue since I always take good care of my phones regardless whether they’re cheap or expensive. So, I knew then it wasn’t due to physical or liquid damage. Now, here are the things you can do if your new device starts to reboot by itself…

First solution: Run phone in Safe Mode to know why it keeps rebooting

When troubleshooting your phone with this problem, it’s imperative that you isolate the problem immediately so that you will know if it’s caused by an app and whether it’s pre-installed on third-party. When you run your phone in safe mode, all third-party applications will be temporarily disabled. So, continue using your phone while in this mode to see if it still keeps rebooting randomly. Here’s how to restart your Note 10 into safe mode: 

  1. Press and hold the Power key until options show on the screen. 
  2. Tap and hold the Power off option until Safe mode shows. 
  3. Touch the Safe mode icon to restart your phone. 
  4. When your phone has successfully rebooted, you will see the text “Safe mode” at the lower-left corner of the screen. That’s the sign that your phone is already in safe mode. 

While your phone is in this mode continue using it like you always do. Pre-installed applications may still work perfectly but third-party apps won’t. If your phone won’t reboot by itself while in safe mode, it means that the cause of the problem is one or some of the apps you downloaded and installed either from the Play Store or somewhere else. In this case, you just have to reboot your phone back in normal mode and then open third-party apps one by one until the phone reboots. Once you determine the culprit, you may reset it first and if your phone still keeps rebooting after that, then uninstall it. 

On the other hand, if your Galaxy Note 10 still keeps rebooting even in safe mode, then move on to the next procedure. 

Second solution: Reset all settings of your phone

If your phone still keeps rebooting even in safe mode, the next thing you have to do is to reset all its settings. This will bring the phone back to its factory configuration without deleting your personal files and data. So, there’s no need for you to backup your files. Here’s how to reset the settings of your phone…

  1. From the Home screen, swipe up on an empty spot to open the Apps tray.
  2. Tap Settings > General Management > Reset > Reset settings.
  3. Tap RESET SETTINGS.
  4. If you have set up a PIN, enter it.
  5. Tap RESET SETTINGS.
  6. The device will restart to perform the reset of settings.

After this, observe your phone closely to see if your Phone still keeps rebooting on its own. If it still does, then move on to the next solution.

Third solution: Delete the system cache

After doing the first two procedures and your Note 10 still keeps rebooting randomly, then what you have to do next is to delete the system cache. It’s possible that it’s corrupted or has become obsolete. That could be the reason why your phone has this performance issue. If you delete the system cache, it will be replaced with a new one. Here’s how it’s done…

  1. Turn off the device.
  2. Press and hold the Volume Up and Power keys.
  3. When the Galaxy Note 10 logo shows, release all three keys.
  4. Your Galaxy Note 10 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 
  5. Press the Volume down key several times to highlight wipe cache partition.
  6. Press Power key to select.
  7. Press the Volume down key to highlight yes, them and press the Power key to select.
  8. When the wipe cache partition is complete, Reboot system now is highlighted.

Press the Power key to restart the device.

After this procedure, try to see if your phone still keeps rebooting by itself. If it still does, then move on to the next procedure. 

Fourth solution: Backup your files and reset your phone

If your phone still keeps rebooting after deleting the system cache, then it’s time for the ultimate solution. A master reset should be able to fix this problem but we are often hesitant to suggest this procedure without first exhausting all possible solutions as you may end up losing some of your important files and data. However, at this point, there’s no other choice but to reset your phone. But before that, make sure to create a copy of your important files and data as they will be deleted. After the backup, remove your Google and Samsung accounts so that you won’t be locked out of your device after the reset. Here’s how you reset your phone: 

  1. Turn off the device.
  2. Press and hold the Volume Up and Power keys.
  3. When the Galaxy Note 10 logo shows, release all three keys.
  4. Your Galaxy Note 10 will continue to boot up into the Recovery Mode. Once you see a black screen with blue and yellow texts, proceed to the next step. 
  5. Press the Volume down key several times to highlight ‘wipe data / factory reset’.
  6. Press Power button to select.
  7. Press the Volume down key until ‘Yes’ is highlighted.
  8. Press Power button to select and start the master reset.
  9. When the master reset is complete, ‘Reboot system now’ is highlighted.

After the reset, set your phone up and follow on-screen instructions. I hope that we’ve been able to help you fix your Samsung Galaxy Note 10 that keeps rebooting by itself.
