I was wondering why we can’t see music on a phone on screen. Obviously there’s an arrow to access the data just like USB Data I can see when I press the right arrow. Is this coming or is my U/I not working right?
I wouldn't expect it to show anything there. That is streaming audio, or in other words just relaying the audio output of whatever application happens to be outputting audio at the time (navigation, notifications, streaming music services like Pandora, or yes, music resident on your phone). So that interface is not accessing media directly. If you want to see media files & folders on your phone I think you'll have to plug into USB.
