This is only on some Android devices. By the way did you download the most recent version ? That should have fixed this bug. (I think because I cannot verify since I don't have the problem on my phone) Please tell me if you still have the problem with the latest fix so I know if it worked or not.
Hmm, shit. As far as I heard from other people it seemed fixed... Well sorry can't do much for you. Only option you got if you want to play on phone is using Joyplay.
