That's not exactly what I meant, filters of course should be preserved. By junk stuff I meant: music player/library, timers, track scanning, wi-fi transfer stuff and other not BTR3 related settings. All we need is to start the app and see the frame with BTR3 settings immediately. Just like its made for ES100, only settings, nothing more. Besides, all that excessive stuff doesn't work well, the programmers spend a lot of time trying to fix it instead of adding useful things like EQ. Check the last few updates of the app, nothing useful is made. Just admit, nobody needs it and cut it out and the time will be safe for important things to implement. Nobody will ever use fiio app as a music player when there is always a built-in music player and way better alternatives on google play.
