I bought a Garmin vivosmart activity tracker, and it includes bluetooth media controls: a play/pause, next track, previous track. All three buttons just play/pause. Being able to skip tracks without taking the phone out of my pocket would be very nice. I realize there are Bluetooth control options in the settings menu, but none of them seem to have any effect. Perhaps I'm doing something wrong? Thanks, love the app; I recommend it to everyone whenever I can!
