When I make a call I can't hear through the earpiece; neither the outgoing phone ring nor the person who picks up. I can hear these on speaker phone and I if I plug in an earpiece; both just fine. It is ONLY the earpiece receiver that seemingly doesn't work. I've verified this using the memo app as well. I've done the soft and hard resets and reset all settings and reinstalled ios. I've done the cleaning out of the audiojack and made sure nothing is blocking the reciver, etc...I can't tell you when I first noticed this issue since the phone has not been used in a while. Assuming this is a hardware issue what is the most likely problem that is KNOWN to cause this issue and actual fixes (for example, cable X got unplugged on the board).
thanks, pete
