Since I installed 4.1 it seems that Bluetooth is MUCH more sensible to distance, for example if me and my friend stand back to back, it loses connection, this didn't happen before. And there is much more lag now. I tried all the games I have, NOVA, BIA2, Modern Combat: Sandstorm, and all of them lag/disconnect. It seems to be from 4.1, but they are both running 4.1 so I don't know what to say, but it's annoying. Does anyone else have this problem?
