I've had this phone for a week now and today it developed something new. When I plug in the battery charger, the touch screen becomes almost entirely non-responsive. When I attempt to slide the Lock Screen away it either won't move or I can get it to slightly move but it bounces right back or even sticks halfway. If I unplug the charger and wait about a minute it's back to working fine again. I've removed the battery a few times now to see if this helped but nothing seems to help. It didn't do this till today. Anyone else run into this problem and if so how did you remedy it?
