Okay, I've had the Galaxy Ace maybe 2 weeks now? Worked perfectly. I was listening to some mp3's with the default headset you get with it. All of a sudden when I stop listening to music because I'm watching a movie, my headphones stop working fully. Only one ear works, but when I push the plug down deeper into the jack, sometimes both ears work. I plugged in another headset, and still only one ear works, but when I twist the plug/jam it in deeper, it sometimes works aswell. What is wrong? :/
