So lately when I call someone on the phone they complain that they can't understand me. I can hear them perfectly in the ear piece. This happens from multiple locations so I don't think it's a network issue. Today I reset my carrier settings to no avail. As I called my mom I turned on speakerphone and she said it got way better and she could understand me. Does speaker phone use a different mic setup or can anyone explain how this would fix my issue? Thanks.
