General issues?

[Overlordkairu]

I checked the FAQ and searched using the handy search button.
I am currently using the Samsung Galaxy S4.

and I cant find fixes for various things ill post:

1) I cant get the D pad on my bluetooth gamepad to work. All the other buttons do is there a setting I need to change?

2) The sound is really quick in some games is there a simple fix?

3) Some games flicker what graphic setting do i change?

4)Ive reviewed the working games section and I can't seem to get final fantasy tactics war of the lions working properly. The cut scenes load in the bottom left corner of the screen. The sound is completely messed up and the game runs very slowly is there a universal fix for all that?
