"previous" button not working

  1. I play (shuffle “on”, repeat “all”) song A, skip forward to song B and try to replay the previous song A by pressing the previous button - but song C is being played. Why is the “previous” button not working?
  2. Playlists are not working - someone else in the forum already realized it.

You should have tested it only once to realized, that’s all crap. Try out your shit before you sell it!
BTW, everything was working fine with the former Clip Zip+.
