Hi. Newbie here. I have an iPad 2 that hasn't given me any problems until yesterday. The problem occurred after my wife turned on the iPad and the display showed smaller app widgets, spread out and the screen rotation wouldn't work. I tried to look in settings but all I got was a blank black screen. Some apps worked though. I fixed the problem by respringing but I would like to know how the problem happened in the first place. When ever I power off, the iPad reverts back to the awkward display. Help.
