Fix Random Reboots or Shutdown on Galaxy S20, S20+ or S20 Ultra

Check for hardware damage

If your Galaxy keeps restarting by itself after it was dropped or hit by a solid object, the most likely cause of the problem is bad hardware. In this case, the best thing is that you can visit your local Samsung store or Service Center so a qualified Samsung technician can examine the hardware. If needed, they may send it in for repair or replacement.

Clear Cache from Recovery Mode

In case you don’t know what is recovery, the first thing the bootloader rings up is recovery. Recovery Mode refers to a special bootable partition, which contains a recovery application installed in it. And you can fix some problems with your phone. Follow the steps to clear cache from recovery mode:

Turn off your phone.
Once it is turned off. Press and hold the power/Bixby and volume down button simultaneously until the Android logo pops up.
When the green Android logo displays, release both buttons.
The Recovery screen menu will now appear
Use the Volume button to go to Wipe Cache Partition then press the Power button to confirm the selection.
Wait until your device wipes out all cache or temporary data from the system partition.
Press the Power button again to reboot the device.

This clears all the temporary data from the device. And then it works like new.

Simple Reboot or Forced reboot

Well, I think you already know how to restart your phone. So just restart the device and see whether it solves the issue or not. Restarting a device is always the ultimate solution for any issue. Not only Pixel but this applies to each and every electronic device. I used to tell my mom to restart her device if she faces any issue with her smartphone.

Well if you still need to know how to restart then, here is it: Press your phone’s power button. On the screen, tap Restart.

The other way of the reboot is as follows:

Press and hold the Volume Down button.
While holding it down, press and hold the Power key.
Keep the button held for 10 seconds, it will be restarted automatically.

If this doesn’t work then head to the next method.

Rebooting your device regularly at least once every week can be beneficial. If you tend to forget things, we suggest that you configure your phone to reboot on its own. You can schedule it to do this task by doing these steps:

Open the Settings app.
Tap Device Care.
Tap the 3-dot at the top.
Select Auto restart.

Update to Latest Software

Open Settings from either the Quick Nav menu or the launcher.
Go to the More tab, then tap on About device.
Tap on the Software update.
If a system update is available, you’ll see the option on the screen. Tap Download and Install.
If your system is up to date, you will see a message stating that the system is up to date.

That is all. You have successfully checked for a system update on your Samsung Galaxy S20 (Plus) and S20 Ultra.

Here are a few things that are needed to take care of while updating your Samsung Galaxy S20 (Plus) and S20 Ultra or any device:

Your device must be connected to the internet.
Your device must have enough space to download the update.
Your device should have enough charge, more than 50% to install the update.

Troubleshoot in Safe Mode

In case you don’t know what is safe mode, in safe mode, the system temporarily disables all third-party applications you installed on your device. By doing this we can figure out which app is occurring the problem. Follow the below step to turn Safe Mode on:

Turn OFF the device.

When the SAMSUNG logo appears on the screen, release the Power key.
Immediately after releasing the Power key, press and hold the Volume down key.
Continue to hold the Volume down key until the device finishes restarting.
Safe mode will display in the bottom left corner of the screen.
Release the Volume down key when you see Safe Mode.

After figuring out the apps which are creating the problem, follow the below steps to uninstall it(if required):

Tap on Apps.
Tap See All Apps.
Tap an app that you want to uninstall
Tap Uninstall.
Tap OK to confirm.
