My wifes Incredible started shifting the home screen to the right without any touching. When its centered the screen begins swiping to the right as if a finger was there. In "all programs" it starts highlighting apps as if I was touching them but I am not. I have tried G-sensor calibration, keyboard calibration, restarts and the closing of apps but cant find where the trouble lies. Is it possible the touchscreen is now defective? Thanks for the help!
