overlay controls stuck in corner, gamepad unresponsive

[number1nub]

please help, the controls are stuck in the corner which isn't a big deal to me because i want to use my moga hero power. but i cant get my controller to work and i don't see where to map the controls. sorry if this is a nub issue, i couldn't find anything on the forum. i had installed the google play version beforehand. i uninstalled and wiped the folder before installing the newest build.
