Thanks! I think you should notify your findings to Xtream Software Development so that they can update their list of working Android devices and their list of working audio devices.
Good news for FiiO E17 owners : the Galaxy S3 with USB Audio Recorder PRO interworks with the FiiO E17 USB DAC/amp
music stored on Galaxy S3 > USB Audio Recorder PRO player > digital USB audio out >> "USB OTG" cable >> FiiO E17 >> headphones
Does that mean I still can't use E17 to stream Spotify on US galaxy s3? Thanks!
