phone flashes white screen to the left sometimes when on phone

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

Sounds like it could be an issue with the app or a system glitch, maybe with the package installer or an app update. Try restarting your phone, clearing the app’s cache, or checking for software updates. If it keeps happening, you might need to uninstall and reinstall the app, or if it's affecting more apps, a factory reset might help.
