iPhone 5 won't pick up voice during calls
Hi,
I am a new iPhone user, and have just gotten a new iPhone 5 with Sprint with iOS 8.3 installed. It works just fine except for one thing: when I try to make or receive calls, the caller cannot hear me at all, although I can hear them just fine.
I've tried turning off celluar data, wifi, LGT and messing about with other settings to no avail.
Any help in resolving this annoyance would be greatly appreciated.
iPhone 5, iOS 8.3
