Me rooted. I found the problem to be with the launcher. Seriously... But i'm still using stock launcher because i find it simple enough to be loved but everytime i need play game lagless, I must clear ram(stock launcher also got cleared) then launch directly from prevously opened app list ( ) That way, the launcher won't be running when i'm playing game. Lagless...

I ain't on cow's rom. I'm just rooted. Still stock rom.
Erm... Have you dealt with android before? Are you using one? Hmm... I can kill the launcher while playing game just for the game to be smooth. When you go back to home, launcher will still need to be launched. I got no problem with serious rebooting. Once in a while because I always try to open whole web page flash game on it. Something too intense for this phone... Actually, there's nothing called patches. First of all, when you want more access, gain root access. Then you can edit scripts, use custom roms etc etc. There's no big problem for hardware of this phone. It's actually all software based problem. Blame samsung for that. You of course should resort for other phone if you're not having budget constraint.

i am on bionic cow rom but the auto reboot still happen once in a while
