So just recently my screen has been acting wildly on it's own - as if some invisible fingers are pressing all over it. I read through a bunch of threads online and other people only seem to be having this problem related to charging the phone. Mine does it whether or not it's plugged in. I use the stock charger that it came with, haven't inflicted any major trauma to the phone, no water damage or anything. The screen just starts bugging out, scrolling randomly, and clicking all sorts of buttons. It's become really unbearable to use, especially tonight. Can anyone help me out?
