I've searched and look around, most forums are in the s3 and s5. It started yesterday I think on my way home had my s7 plugged into my Jeep via aux cord. The right speakers got a little quiet but didn't think much about it. Today I was listing through my lg tones and only the left ear bud played, looked In settings for mono and it's set to stereo and balance is in middle. I don't know where else to look, was listing to Google play music.
