SeannyM, just tested, I believe those problems I'm experiencing are linked to fastmem + bt. Hardware keys just not responding/freeze if I'm running any game with fastmem turned on. At some point I've got "bt share process crash" system report, that could be fastmem uses RAM till all the other processes are terminated, including the one responsible for dc3 (dc3 native app), (even gamepad turns lights off), few times live wallpaper was turned off. Without fastmem all worked fine, thanks for fixing L/R :-)
