Just got it, i didnt want to get a iphone because you almost have to JB them to get the most out of it, i thought android was different, but now it seems i need to root my s4 to play any games i back up? I tried assassins creed, raven sword, avengers, the only one that almost worked was galaxy under fire the only one you dont have to put into the .obb folder, but the graphics where really glitchy. Also at first I couldn't transfer anything to the obb folder, instead i had to move it with file manager in the phone, is this why nothing works?
