Had the same problem also. Screen jumping up and down very quickly and randomly from one thing to the next. It became unusable so I took it back and the tech ordered me one after seeing what it was doing. I received the replacement Droid 2 days later. Had it about a 2 weeks now which is about when the first one started flaking out so we'll see. It seemed to act up a lot more after carrying it in my pocket which makes me believe it may be heat related or is that just a coincidence?
