I have an interesting problem. I have no sound during a call. Only way for to use the phone on a call is to use speaker phone. Sound is fine other wise, youtube, pandora, 3.5mm jack, notifications, dialing, all work fine. I even tried voice recorder and iRecord and both record and play back fine. Phone is up to date and did factory reset twice. I don't have a bluetooth device so I cant check that but its not turned on. Never rooted.Not sure if this would be covered under moto's warranty as I have no phone insurance. Never been dropped or wet, phone is in perfect condition.
