How to connect a PlayStation 3 controller to a Sony Xperia Z2 (or any compatible Xperia smartphone)
Using Sony's wireless controller for the PlayStation 3 with Android devices isn't a totally new trick. Apps enabling an Android gadget to pair with a Dualshock 3 gamepad have been around for years. These apps require root access, however, which renders them useless for a huge fraction of Android smartphone and tablet owners. Yet did you know that the Sony Xperia Z2, and a handful of other Xperia devices, for that matter, come with built-in, no-root-required PlayStation 3 controller support out of the box? Well, now you do, and once you're done reading this post, you'll know how to pair one to an Xperia device.
Note: The cable is mandatory only for pairing the controller with an Xperia smartphone. Once that has been taken care of, you can disconnect the two and continue using the controller over Bluetooth.
Note: Look at step 7 in the slide show in case you're having troubles reconnecting the controller to your PS3 console.
Now you can use the PS3 controller to navigate your Xperia's UI and, of course, to play some games. Not all Android games are controller-compatible, however. We can confirm that these work: Dead Trigger, Raiden Legacy, Radiant, AirAttack HD, and Zombie Gunship. Other titles have been confirmed to work as well, including GTA3: Vice City, Sonic the Hedgehog 4 episode II, Switch Galaxy, and Max Payne. Enjoy! Basically, if an Android game is said to have controller support, chances are it should play along nicely with your Dualshock 3 controller.
