Had my phone on my desk at work. Nothing running (usually have it on to listen to music). It was extremely hot to the touch this morning. Should I be concerned?
Stange! I've had mine since the day they came out. Never had any heat issues with mine.
Battery might be on it's way out? Check in android system for battery usage stats?
It seems some app is running constantly. I dont have any issues with mine. Have you done update, maybe factory reset? I personally disable at&t apps I dont use.
