Yesterday while surfing around and also checking the forums here, the screen on my ipad just changed. It's definitely a lower resolution, kind of grainy, almost looks likes teeny tiny grids. Letters aren't as sharp, etc. Do you have any idea what may have caused this? It's freaking me out a bit! I've checked the settings and can't see anything out of order there. Thought about resetting it to factory settings but am wondering what, if any, data might be lost. The only thing I did was delete an app, though actually that may have been the day before, can't recall. Do you think an app could have done this? Am grasping at straws here as I just can't figure put what caused this. Your thoughts and insights are greatly appreciated.
