I can hear everyone on my end but the people I call can only hear me if my IPhone 4S in on speaker. Does anyone know why this is or how to fix it.
Maybe your muteing it but not sure. Maybe there's a receiver problem. I had the opposite problem I couldn't hear anything untill i used speaker phone so they tweaked inner workings of the phone. And it's a apple known issue it could happen. So maybe they could fix it or replace it with vzw / apple.
