Heya, here's a little tip. Last night i noticed that the apps i was using werent making any sounds, not even after checking the volume and everything. So i started poweramp, my music player app, and tried to play music to check if thats working, and i was surprised to find out, that while the music was not coming from the phone's speaker, it was coming out of the ear piece, which you use for phone calls. Im not sure if that is a common bug, but seemed weird to me. Anyway, i backed everything up and reflashed the firmware im on, 10 minutes process, and its back to normal. This is also what i did to fix the camera, when it stopped focusing. Hope that helps anyone.
