If your Galaxy S10 is rebooting by itself and you can't pinpoint the problem, then you should check the instructions below and learn what can you do to fix your device. Note that the steps you will find below should be used by advanced users.

The Samsung Galaxy S10 smartphones might develop some firmware issues, and these are making your phone perform worse out of the blue. Also, history has shown that from time to time some Samsung Galaxy units might start getting a bug that makes them restart randomly.

Random reboots might be triggered by firmware issues, hardware overheating, bad applications installed from unknown sources, internal storage at its full capacity, or others that I can't think of right now.

How to Repair Samsung Galaxy S10 Random Reboots:

If your device is experiencing random reboots then the first think you should do is to wipe clean the system cache and see if that happens. Wiping the cache of your smartphone will not delete any data from your device, as it will only clear the data loaded by each app you've launched on your Galaxy S10 since you powered on the first time.

Wipe Samsung Galaxy S10 Cache Partition using Recovery Mode:

The Recovery Mode is a hidden system menu that allows advanced users to apply updates from adb, remove data file, wipe a smartphone completely, wipe cache, and install extra system apps without the device being booted on. Here's how to wipe the cache partition:

  • power off the Galaxy S10.
  • press and hold Volume Up + Bixby + Power buttons at the same time.
  • release the buttons when the screen turns blue and "installing system update" text shows up.
  • when the Recovery Mode menu loads you simply need to use the Volume buttons in order to navigate through the settings.
  • select 'wipe cache partition'.
  • confirm selection by pressing once the Power button.
  • after you're done you can reboot system in normal mode and you are done.

Other Random Reboots fixes you should try:

You should try and install the latest firmware updates for your Samsung Galaxy S10. You can do it by going to Settings> Software Update and tap "Download and Install" option in order to search for new firmware files.

In case a new Android 9 Update is ready for your Galaxy S10 phone, then you will have to confirm the process and your device will do all the rest. In case after you complete the update your smartphone still experiences random reboots, then you can try some other fixes below.

In case your device has started to perform worse in terms of performance after you've installed some applications, then you can boot the phone in Safe Mode and use it to remove such apps easily.

When your Samsung Galaxy S10 runs in Safe Mode it will load with the default original applications the device featured on the day you bought it. Also, you will be allowed to remove the extra apps one by one and see if you can find the one that is making your Galaxy S10 device reboot randomly.

Here's how to boot your Galaxy S10 in Safe Mode:

  • press the Power button for a few second to load the Power options.
  • now press and hold the "Power Off" option.
  • Safe Mode icon will load.
  • tap it once for your device to boot in safe mode.
  • after the device reboots it will show a "safe mode" text on the screen.
  • use the Safe Mode to troubleshoot your device: remove all the apps that you think might interfere with your phone's boot process and maybe you will find the culprit.

In case you haven't managed to fix your Galaxy S10 random reboots, then you might want to check and see if its hardware overheats. If the phone feels hotter and it gets rebooted every time you use apps that require a lot of power, then the issues is in the hardware, and you will have to send the device into a repair shop. If the phone is under warranty make sure to explain all the problems you're having using it, and they should be able to give you a different unit for you to use.

If you still cannot find the problem, then you can try to factory reset your smartphone. Make sure that in case you want to factory reset your Galaxy S10, then you will create backups for all your important data files and applications.

Note that by factory resetting your Galaxy S10 you will restore it to its original state when you've first bought it. Here's how to factory reset your Galaxy S10:

  • power off the phone.
  • press and hold Volume Up + Bixby + Power buttons at the same time.
  • release the buttons when the blue "installing system update" screen loads.
  • wait for the Recovery Mode menu options to be loaded.
  • now you can select using the volume buttons the "wipe data/ factory reset' option.
  • press Power to confirm the factory reset and wait for the device to complete the process.
  • reboot the Galaxy S10 in normal mode when you're done.

In case none of the methods above help your fix the Galaxy S10 random reboots, then you should try and contact Samsung directly and see if they can help you determine the problem. If your device is still under warranty, then you should have any problems in returning the unit and getting another one to replace it.
