hello all droid users. I have a quick question. I am actually writing for my son who is at work. I saw his phone on the counter this morning so I decided to plug it in so that it would be charged in time for him to go to work. I plugged it in and waited about 1/2 hour, came back, phone felt warm but would not turn on. a friend of his called me about an hour ago, and said phone still not turning on...any thoughts?
