I bought a PS3 controller from amazon, model #CECHZC2U that would pair with the phone only no buttons would show as being pressed and nothing else would work. Then I borrowed a CECHZC2Ua1 that worked just fine. I then bought a CECHZC2Ub2 that works fine as well.
"DroidEmu" and the six axis apps from the play store work great together! The game clip is great too, fits the HOX very snug, doesn't feel like it would ever fall out.
