This just started happening. When I am on a call, the voice of the caller on the other end gets suddenly loud, as if I am on speakerphone. I didn't press the speakerphone button, and it doesn't show as green. If I press the speakerphone button, on and off, it goes back to normal. When I called Samsung about this, they said they have not had any other reported problems like this, and that I will have to pay to have it repaired, since it is out of warranty. Is anyone else having this problem.?
