I bought my phone on the day it launched and I've had no problems with it up until now. It was working just fine tonight, then I went to Verizon to pick up a new screen protector. The guy put it on for me and immediately after I left I realized that the sound on my phone wasn't working. Well, most of it isn't anyway. None of my notifications or look screen sounds are working. None of my game sounds are working. But for whatever reason, the sound on YouTube works. That seems to be it. Anyone have any suggestions for this problem? I'm really bummed because I hadn't had a single problem with it. I've double checked all my settings, volume is turned up, and I've restarted the phone. Nothing has fixed it.
