How to tell if phone mirrored or hacked I keep having apps on phone I didn't install yet cannot disable. Phone screen keeps doing its own thing. Google maps timeline keeps being edited. Lots of unusual stuff like that.
It usually can happen because of fall of the phone from height. Maybe your display touch is broken, so it's touching the apps or texting somethings by itself. Try to hard reset your phone. I am not sure but it can help you. Otherwise, you should give your phone to hardware repairer.
