I have come to find that on the audio player that the playback speed slide bar is not very mobile phone friendly , the problem is that when I scroll down sometimes I accidentally bump the playback slide bar and the audio jumps to high speed and I have to go back and set it back to the desired speed which I prefer 9. Also when I carry my phone in my pocket it will suddenly play at high speed once again , because the selector got bumped , is there another place this feature could be put on the player or different type of slide bar or different way to set the playback speed ? I'm sure others have had this problem
