Alright so my buddy has a D2G and 3 days ago the digitizer just stopped working. The phone is 3 months old. No water damage. Just up and quit working. Everything else seems to be working fine though. Like if you hit the power button the screen turns on and off and you can scroll through the power options with the keyboard. Still recieves calls and texts and everything as far as the OS goes is intact. The digitizer just doesn't work. It isn't rooted. What could this be?
