So I am wondering if anyone else has had people on the other end of their phone call say they sound like they are in a tunnel. My friend can be next to me on his 5 on Verizon and it not sound the same? Would this be a microphone breakdown issue or just the network? Im in Tennessee and we have great 4G in the area I am in. Wanted to know if anyone else had any complaints with this? The Verizon reps really cant do anything over the phone since its the only phone I have. They had me do a network reset and check off a new setting or two about data roaming but I still get get the same complaints about sounding like I am in a tunnel or talking to softly. And I do not have a case on the phone either. Thanks in advance!
