Dissidia 012: Duodecim Final Fantasy

[IronAvenger]

Not sure if this is the right place.
I'm playing in a Moto G 2nd Gen, Lollipop 5.0.2, most recent ppsspp version
When i try to unlock a character with pp it proceeds to a screen showing the character but then i can't exit that screen, i've tried every button and nothing.
