I have three devices listed under "Show Available Devices" section on my phone:

-SM-N9005 (This device)

-SM-P600 (Unavailable for playback)

-SM-P600

How can I get rid of the duplicate SM-P600 tablet that is always listed as unavailable (under listing for available deiveces)? My desktop client does not list the unavailable one.

I suppose the strange duplicate device could be behind my playback problems that started when Connect was introduced. Frequently when I start playback on my tablet, it plays the song for half a second before pausing again. I must switch the playback in my phone to SM-N9005 (This device), restart the song and then while playing transfer it to SM-P600. This fixes the problem for some time.
