To fine tune your D-pad controls, try these tips:
  1. You can re-size the D-pad and fire controls at any time. To reset these settings during a game, select Options, then select Control Type, select one of the D-pad control selections and stretch/pinch the D-pad and fire button to your liking.
  2. The position of the D-pad and fire buttons can also be set to a fixed position or to appear wherever you touch the screen.
