Hi, I have recently discovered a bug (not sure if already reported, but I thought I’d report anyway), when using the ps3 controller linked through the sixaxis app. I use the retroarch menu to load/save states using the home button on the ps3 controller, and I find the screen freezing on the eleventh time opening the retroarch menu. The app continues to run in the background, so I can hit the home button on my phone and return to my homescreen and simply re-open retroarch and my game appears where I had left it with the screen unfrozen, however it becomes a pain in the ass after a while.
My phone model is an Xperia T.
Hope this helps, and thanks for the great app.
