[-qo69vc1_m7k]

Hi, 

Sorry for my bad English. 

I became a S3 Gear Frontier to use it in the Gym, for music without Smartphone

I download the Playlists, and all work fine..... to the moment without WLAN or Smartphone connection.

At this moment I can't play t

Music, change songs etc. Only 5 seconds play one song.

I have listen that other people have the problem, but I find no workaround. 

Can anyone help me?
