Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.

Are you doing something special with the phone when the screen starts to flicker? For example, opens an app or similar. You can always try to boot the phone into safe mode to exclude problems related to third party apps:
