Hey. My phone is x10 mini pro

. I have bought gameboid, but when i start any game, i can only use one button on the touch screen at one time or only one at all

e.g that i play some racing gaming i can use B(speed) but cant turn right or left on the screen. Or if i touch right+left, it will brake.
I can use my keyboard's left+right, but the distance are too long between the buttons.
Help plz!

I alrdy tried to search on the forum, but couldnt find any suggestions
