Begin playing music on your phone/tablet using the default music player app (Google music for Android and 'Music'/iTunes for iOS).
On the Fusion Bio, swipe to the left of the time/date (and battery %) screen(s) to select Apps , then swipe to the second Apps screen and select the music note icon.
Music controls will then appear on-screen, which will allow you to pause, play and skip between songs playing on your phone/tablet.
Music control functionality may timeout if you pause music for an extended period of time without using the music control function on the Fusion Bio. If it does timeout, simply begin playing music on your phone/tablet and resume controlling played music using the Fusion Bio.
We are always looking for new ways to expand music control functionality and do hope to support controlling music played through third party music player apps like Spotify and Pandora. If you have any suggestions for improving music control, feel free to share them with us via the in app feedback function or by emailing us at firstname.lastname@example.org.
