Crisis Core Final Fantasy VII

[trunks182]

hey guys, on my galaxy s2 i don't get full speed everywhere. there's certain places / direction i face and ill drop to 40 fps. If i put my frameskip to 2 it seems to be 60fps always, but the screen seems to keep flashing black over and over. i've tried pressing the fast forward button as someone else suggested but that doesn't get rid of it.

can anyone help?
