Fixing Galaxy S10 Plus that keeps restarting by itself

As I mentioned earlier, performance issues are often due to firmware problems but in troubleshooting this kind of problem, we need to be thorough to be able to determine what the problem is. So, here are the things you need to do to make your phone run perfectly again…

First solution: Restart your phone in Safe Mode

I once encountered this problem with my phone before and I knew right off the bat that the cause of the problem was a third-party application because I always take care of my devices and don’t sideload sketchy applications. However, there are applications from the Play Store, especially game apps, that require a lot of resources. That’s one of the reasons why the phone would reboot by itself–when there isn’t enough RAM or the CPU could no longer cater more processes.

My point is, it’s very much possible that this issue with your phone is caused by a third-party application that’s why it’s important that you restart your phone in Safe Mode to temporarily disable all downloaded apps. Here’s how it’s done:

  1. Turn the device off.
  2. Press and hold the Power key past the model name screen appearing on the screen.
  3. When SAMSUNG appears on the screen, release the Power key.
  4. Immediately after releasing the Power key, press and hold the Volume down key.
  5. Continue to hold the Volume down key until the device finishes restarting.
  6. When Safe mode appears in the bottom left corner of the screen, release the Volume down key.

If your Galaxy S10 Plus doesn’t restart while in safe mode, then it’s confirmed that the cause of the problem is a third-party application. Try to uninstall the app you installed about the time when this problem started.

However, if the phone still reboots without your intervention while in this mode, then it’s a possible firmware problem. Continue to the next solution.

Second solution: Reset all settings

It is also possible that some of the settings have  been changed or messed up. It’s difficult to determine what setting to change or what’s causing the issue so the best thing you could do is reset all settings so that they will be brought back to their default values. In doing this procedure, it would seem like you’re actually resetting your phone only that none of your files and data will be deleted. Here’s how it’s done:

  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 and your phone still keeps restarting by itself, then move on to the next procedure.

Third solution: Delete the system cache so it will be replaced

Another possibility that you have to consider is that the system cache may have been corrupted or is already obsolete. Random reboots may also result from this problem. The good thing about all this is that, you can actually delete the system cache and your phone will create a new one. You can do so by wiping the cache partition of your phone and here’s how it’s done:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Galaxy S10+ logo shows on the screen, release all keys.
  4. Press the Volume down to highlight ‘wipe cache partition’.
  5. Press Power button to select.
  6. Press the Volume down key to highlight ‘Yes’.
  7. Press Power button to select and wipe the cache partition.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

Wait until your phone becomes active and then continue using your phone to know if it still keeps restarting on its own because if so, then there’s another thing you need to do and this time, it could be the end of the problem.

Fourth solution: Hard reset your Galaxy S10 Plus

That’s right, a master reset is needed at this point in time. This will rule out the possibility that the random reboots are just due to a firmware issue. But before the reset, make sure to create a backup of your important files and data as they will be deleted. After the backup, make sure to remove your google and samsung accounts so that you won’t be locked out of your phone after the reset. Once everything is set and ready, follow these steps to reset your device:

  1. Turn off the device.
  2. Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
  3. When the Galaxy S10 logo shows on the screen, release all keys.
  4. Press the Volume down to highlight ‘wipe data / factory reset’.
  5. Press Power button to select.
  6. Press the Volume down key to highlight ‘Yes’.
  7. Press Power button to select and start the master reset.
  8. When the master reset is complete, ‘Reboot system now’ is highlighted.
  9. Press the Power key to restart the device.

If your Galaxy S10 Plus still keeps restarting on its own after the reset, then it’s time you brought it back to the store or shop so that a technician can check it for you. At this point, it’s safe to assume that the problem could be with its battery or the firmware needs to be re-flashed.
