So this looks like a Samsung issue then..... Were you running stock TouchWiz on your devices? What version of android were you using? I've looked all over the internet for someone with a similar problem with no luck. The strange thing is that I also get the lag on my Asus Nexus 7 with both my dualshock and moga.
Can the kernel affect Bluetooth performance because I've got a custom kernel that came with the AOSP rom?
