phone flashes white screen to the left sometimes when on phone

[Alex Hobson1]

when i open up an app or use my phone to do anything sometimes it will keep flashing a white screen to the left like mad and it won't stop for about a few seconds or so is there any way to stop it from doing this think it has something to do with package installer but not sure

Which Xiaomi phone? Can you try to record the screen when it's doing that and post where we can see it?

You mentioned "package installer" -- are there any sideloaded apps on the phone, or is the phone rooted or otherwise modified?

Do you have developer settings enabled ?
