Now this has probably been asked many a time before, but I need a little bit of advice to do next. Here's where I'm at. I dropped me iPad 2 which cracked the screen. Although the touch screen still worked, the screen came loose and would not stick back. I decided to remove screen, very carefully, with view to replace. With screen off to one side, I accidentally turned iPad on. When it was on, without screen on it, the slide to unlock was moving a little as though someone was trying to unlock it. Also the screen zoomed in and out by it self. Is this a normal thing that would happen if the screen was off and iPad turned on. Or could I have other problems here? Any help or advice would be much appreciated.
