Hi, I want to point that other manufacturers have included this functionality in their custom ROMs phones since google has been stuck with avrcp 1.0 long time ago. Sony put custom versions of Android in their phones too, so why not to put this feature. Is very funny and/or frustrating that MW600 is fully functional in devices like iOS 5 devices and Galaxy S3 (I've tested it on those), also I have reports that it also works in Motorola phones, but no in any Sony Phone/Tablet. Sony is near to make the worldwide release of Jelly Bean update on most of its recent models (Xperia S included). It's the perfect opportunity to solve this problem and avoid a lot of claims for misleading advertising.
