I recently purchased a set of earphones (HTC RC E160) with music controls (next, play/pause, previous buttons).
Strangely, they do not appear to work on my Samsung Galaxy Ace. The play/pause button works properly, but the 'next' button does the same thing as the play/pause button and the 'previous' button does nothing at all.
I've tried making a testing Android app which tries to capture the button presses and obtain information about them. The previous button just goes completely undetected, but the next and play/pause buttons both display identical information.
Does anyone have some insight into what is going on? I'm unable to tell if my earphones are faulty, or if there is a compatibility issue.
EDIT - just tried on a Samsung Galaxy Tab, all three buttons work, except the next and previous buttons alter volume instead. Confused.
