So, I was driving to work this morning and received a phone call from my wife. Answered the phone and said hello. Nothing in return. Hung up and kept driving. Spouse called again and the same thing happened. This continued repeatedly until we determined that it was being caused on my end. Calls go thru but there is no volume coming thru the earpiece. I can receive calls on speaker phone with no issues. But trying to have a call other than using the speaker phone does not work. I have tried restarting the phone to no avail. I have checked to make sure that the in call volume setting is up. Still nothing. When I put the phone down last night when going to bed the phone was working with no issues. Then over night something happened. Any thoughts?
