All buttons are not recognised by the game except of the D-pad and the back button.
They don't work in game and can't be rearranged in the customize menu.

Tommaso has said that the Xperia Play should work again with the addition of controller support in 0.12.0, but it seems that's not the case. Source: https://www.reddit.com/r/MCPE/comments/2sx5dv/the_xperia_play_situation/
The buttons still don't work, except of the D-pad.
currently it is hard for me to test this, because my display cable is broken, and I have no picture when sliding my Xperia Play open,
but I hear no sound when pressing L/R to place/remove blocks, so I assume the still don't work.
