I've had this problems a few times in the last several days. The first time I really noticed it was three days ago when I was at the beach and the phone became uncomfortably hot in my pocket. It wasn't charging and I had barely been using it at all. It got rather hot yesterday when I was about one minute into a phone call. I've also been having charging issues, if anyone has any thoughts on that. Posted a thread but I don't believe they've put it up yet. It's frequently been saying it's charging but just stagnating at the same battery percentage, or beeping at me repeatedly saying it's connecting and disconnecting. My roommate got the same phone one day before me from a different Sprint store and has been having the exact same issues. She also had a small clear strip with panels fall out of the charging port last night. Somehow that seemed to help her phone recognize the charger.... I've seen another user say that a piece in the charging port is supposed to be centered and that if it's angled more towards the bottom of the opening (like ours appear to be) it could cause charging problems. At this point I hate the phone and am almost ready to go raise hell and demand an iPhone 5 or something. Any thoughts?
