On my Droid, when it is not being charged on occasion the screen does not turn on when I attempt to turn it on. I press the top button to turn it on and the led touch lights below the screen turn on and i can unlock the screen and do everything but the screen remains sleeping. Sometimes it turns back on after one try, but sometimes it takes 15 to 20 tries to get the screen to turn on. Does anybody know why this is happening?
