Anyone having audio problems with their Samsung Note 5 or Samsung S7?

[AC Question]

I experienced this first with the Note 5, got an S7 and am still having the same problem. It's so weird. What happens is the I am speaking on the phone and the person I'm talking to can't suddenly hear me. I can still hear them though. They describe it as I fade away. I had my Note 5 fixed under warranty and it worked for a short while and then started doing it again. So I got an S7 and I can't believe it's happening with that too.
