Hi there, i just got my HTC EVO 3D for like 2 weeks and all good since like 2 days. For some reason sound was very low even when it was on max, after a while I noticed the problem is the rear speaker its permanently turn off, currently im just listening the front one. So i was scared that the phisical speaker was broken, then i tried to make a call and put the phone on speaker and i was relieved to hear the speaker was loud and good. But it only works on phone calls, not for anything else. When I play a game, recive a call, etc. its totally off. I also tried to open a game while i was doing the phone call with speaker on and I could hear the game clear and loud but only cuz i had the phone call background. Whats going on?
