I wish they would provide one of these firmware updates for the X5III-suffers from the same thing. I installed Tidal, Spotify, BubbleUPnP, Servestream and USB Audio Player Pro--that's it-- and I'm getting those running out of memory messages -176MB remaining. Meanwhile the main HD still has something like 16GB free space for music files. What was FiiO thinking??!! Free up the whole internal drive for what ever you want to install, like every other Android device!!!
