My Phone Flickers (A31)

[Ternion]

My phone flickers white for some reason and i couldn't find a way to stop this any ways to fix this?

(Also going to a Samsung Service Center and Hard Reseting it isn't an option for me)

Edit: Also when in landscape mode (when playing a game) my phone tries to go portrait mode any fixes? 

Edit 2: When in dark mode the flicker turns into black and in light mode the flicker turns into white.

Edit 3: When flickering it only covwrs 65% (in top) of the screen.

Things i tried to fix it:

1. Clear Cache Partition

2. Restarting

3. Soft Reset (Restarting)

4. Optimising Apps

Hello there, Ternion! You may try to put your device in 'Safe Mode' 

Starting Your Phone in Safe Mode

1. 1 Turn your phone off. To do this, press and hold the Power button and tap Power off.
2. 2 When the Samsung logo displays, press and hold the Volume down key until the lock screen displays.
3. 3 When the lock screen displays Safe mode will be shown in the lower-left corner of the screen.

In Safe Mode, your phone won't run any third-party apps. This allows you to easily identity and remove the app that may be causing the problem.
