1. Volume rocker buttons don't work when music is playing with the screen on. If I press and hold I can switch to next/prev song but the volume it self doesn't work.
2. Listening to music just stops after a few minutes... I read this is a problem with kitkat because it randomly unmounts the internal storage or something. The problem goes away using Dorimanx kernel but it's a pain to reinstall the new kernel and the CWM after every nightly update.
3. Bypass mode of the Active Display doesn't work.
