hello, i just got the galaxy s3 and i paired it with my sony ericsson BT MW600. the MW600 works well with my xperia arc s and HTC. however, with the galaxy, the middle button (pause/stop) does not seem to work even though both forward and backward buttons are fine. i did a reset for the MW600, then re-paired. the middle button still does not work. anyone have an idea what's going on??
