I'd also recommend Resonance of Fate. Its such a satisfying game when you finally get past a part your struggling with (which is pretty much every chapter). There's not a lot of room for error. The battles look pretty awesome too, certainly a spectacle when your characters are flipping through the air raining bullets on enemies.

It's broken on the iPhone 5s as well, the graphics are all messed up. Their other games seem to work well though regardless of platform.

I feel your pain though, when I tried getting a refund from Square Enix for the android version they denied there was even a problem. There's a section on the play store where you can get refunds by going straight to Google. I think you have to select the "Report a Problem" option in your order list.
