How to fix System UI Random Crashes / Freezes for Galaxy S10:
The "System UI has stopped" error shouldn't be something that you see often on your Galaxy S10, but in case you are experiencing it currently then you should at least try to fix it before turning your phone in to a repair shop.
Force Stop System UI app from Apps menu:
The first thing that you have to apply is to try and force stop the system UI from running and forcing it to reload. This might not work but you can at least try to reload System Ui app.
Do it by going into Settings, and opening the Apps menu. Tap on the three button icon and enable "Show System Apps".
Now you have to scroll through the menu and find the System UI app. Open it and tap on the Force Stop option. Confirm and then wait for the System interface to reload itself. If it doesn't fix the issue, then you should reboot the device by pressing and holding Bixby + Volume Down + Power buttons simultaneously to force a reboot.
Clear System UI app cache:
The System UI app can be accessed and this means that you can wipe its cache. This can be done easily only in case you can access the Settings menu. So, go to Settings> open Apps> and enable "Show System Apps" from the 3 dot menu.
Scroll down and find the System UI, go to Storage and wipe the cache first. Reboot device and it should be done.
Clear System UI app data:
The System UI app data can be cleared and you should do it in case your device's operating system crashes frequently. It can be done like you did above at the "clear cache" method and use the "clear data" option instead.
Reboot the phone after the data is cleared and the problems might be fixed. In case you are still finding it hard to use the device, then you will be forced to try and take more aggressive measures like 'factory resetting' the device.
Hard Reboot Samsung Galaxy S10:
The Hard Reboot method allows you to restart your device in case the System UI crashes and the device freezes without allowing you to take any other actions.
The Galaxy S10 can be restarted manually using a combination of its hardware buttons. So, press and hold Volume Down + Bixby + Power buttons at the same time until the phone's screen switches off. Release the buttons and wait for the device to boot in normal mode.
Upgrade the Android 9 Pie to latest firmware build:
If you can't fix the Galaxy S10 System UI problems using the methods above, then you can try to upgrade the device's firmware to its latest version.
If the Galaxy S10 is randomly crashing and the problem goes away for a while, then it might because of a software problem. Go to Settings> Software Update> and use the "manually search for system updates" option in order to find new updates.
In case a new firmware file is ready for download, then you should confirm the process and wait for your Galaxy S10 to boot in normal mode.
Boot Galaxy S10 in Safe Mode and Check for Bad Applications:
The System related issues you might be experiencing on your Galaxy S10 might also be due to some rogue apps that you've recently installed. In case you know that you've installed such apps, then you will be forced to boot your device in Safe Mode and check for bad apps.
To boot in Safe Mode successfully you need to press Power and wait for the power options to load. Next, tap and hold "power off" menu for Safe Mode option to load.
Tap the Safe Mode option and confirm the boot process. When in Safe Mode you will have only the default apps running, so in case the System UI doesn't crash in this case, then the problem is related to some other app you've installed recently.
You can try to uninstall apps one by one and reboot in normal mode after each app is removed, so that to verify that the device works as intended. To be sure you should remove all the apps that you suspect are interfering with the phone's System UI.

Before trying the last method and removing all the data from the phone you should try to wipe its cache partition first. This process can be done via Recovery Mode. Here's how to do it:
- power off the phone.
- press and hold Volume Up + Bixby + Power buttons at the same time.

- select 'wipe cache partition' and confirm the process.
- reboot your Galaxy S10 in normal mode and you're done with the tutorial.
In case the Galaxy S10 still has issues running, then it would be best for you to try and factory reset it using the last method below.
