How are you able to control your Pandora and Milk apps on your phone through your Samsung Gear 2 watch? I had done this with my Pebble but I am unable to control it through my Samsung Gear 2 yet.
I just start Pandora playing on my phone, open the Media Controller app(NOT the Music Player app!) on the Gear 2, and the play/pause, volume, track fwd buttons all work as they should. It's not a full ported Pandora "app", but the controls work just fine.
Confirmed the media player controls work with one caveat - DO NOT TURN THE WATCH RING!!
Doing this instantly burns through all your Pandora skips!! I have done it a couple times on accident and was stuck not being able to skip songs for one hour. :-(
