Hey guys ive got a problem with my iPhone 4 Basically if a make a call, the volume is fine But if I put my phone on loudspeaker then the recipent complains that they cannot hear me. The same goes for FaceTime conversations, they say I sound quiet? I'm ruling out that it is a microphone problem be abuse it only happens on loudspeaker, other conversation is fine and clear? Has this happened to anybody else? Or does anyone have any suggestions?
