Whenever I hit a button to turn the screen on after it goes off, the screen is all distorted. It stays distorted until I roll the trackball around a little bit, then it works just fine. It's a minor annoyance, but I still want to know if there is any way to fix it? I replaced the LCD screen today and upgraded to 5.0. It never used to do that, and I don't know if it's the new screen or OS upgrade or what, but I know it is a new problem.
