Same story 4 me. Volume rocker keys work only on main page of UAPP - not working on locked device or when UAPP is in background, regardless of 'Use volume rocker buttons' set or not. Since i use the tablet as a car audio source, navigation and car phone, it is a real nuisance - must take eyes off the road and one hand from driving wheel more than often.
