go to https://dl.dolphin-emu.org/builds/ and look for dolphin-master-4.0-427.apk, open gl should work and the only bug is that it rotates the screen, make sure that the dolphin you installed from the store is uninstalled and you have unknown sources enabled in security(or else it fails), its the build I use with my g2 until the screen broke two week ago 
also if you can dump a copy of like crazy taxi(from a friend or someone you know) it runs pretty smooth compared to other games I get 4-6 fps with open gl
