I only get sound out of one ear whenever I'm using the headphone jack. If I use my bluetooth headphones I get sound out of both ears but not through the jack. Took it in to the AT&T store and they tried using an air can to remove any lint etc but problem persisted. She notated my account that she had verified the jack doesn't work and I'm gonna have to call the warranty dept and get a new phone. Not too worried about it since my bluetooth headphones work but sucks cause I do use the jack for my car radio. Oh well...anyone else had an issue with the headphone jack?
