My volume was up the whole way and someone was calling me, but my ringer was not going off. So I answered the call but I heard nothing on the other end. So I ended the call and began to press icons on my phone to see if there was that normal clicking sound...there was no sound at all. No sound coming out of the speaker! So I turned off my phone and tried to turn it back on, but it would not turn back on. So I finally pulled the battery and my phone turned back on with the sound working again...now my phone is back to normal. Such a weird glitch! Has anyone else had this glitch happen to their Epic?
