I had an s4 for a few weeks, dropped it, the screen broke and couldn't use it. It sat for a while, one of my birthday presents from my husband was my fixed galaxy. I've been playing with it and noticed I can't hear anything on my videos. When I plugged my ear buds in it worked fine. I don't know about calls or notifications yet. (Worked late and don't have it switched over yet) how do I get sound working?? I love this phone and want to keep it!!!
