Yes sir. Couple of times. Well, I fell asleep listening to my police scanner app cuz I couldnt find my sounds of the trailer park CD...I woke up, tried to check some sexts messages, and I realized the scanner was still running. So I went to close that and Mr Andriod decided he didnt want to respond to my request, not to mention he was running pretty slow. Soooo, I simply powered off to get a fresh start, and BOOM... Now it wont turn back on
