However, as Android games aren't built with a controller in mind, the experience actually using the controller in-game (we played Dead Trigger) was a bit wonky.
The controller's built-in adjustable spring-loaded clamp allows secure docking of any Android handset (including the Samsung Galaxy S3) or iPhone while sturdy soft rubber clasps protect handsets from being scratched or damaged.
Not only is there a built in controller and a touch-screen on the Vita, it also has a rear touchpad which allows players in Tearaway to poke their fingers up into the gameworld itself.
