Kate Upton and mobile gaming is something I would have conventionally thought of as oxymoronic, but the celebrity's Game of War endorsement serves as a true testament of how far the mobile gaming industry has come.
If you're playing the Android version of Game of War, or pretty much any other game (including emulators), it's much easier to play using a controller. While some Android games have gamepad support built-in, others do not and require something a root app like Tincore to map touches into buttons.
However, if you're playing a game with built-in gamepad support and have a PlayStation 4 controller on hand, it's extremely simple to pair it with your Android device using Bluetooth to get your game on right away.
In order for your Android phone or tablet to view the controller listed as a possible Bluetooth connection, you will need to use a button combination on the PS4 DualShock 4 wireless controller to access pairing mode.
On your DualShock 4 controller, hold down the Share and PS buttons simultaneously until the light bar begins to flash white.
On your Android device, enable Bluetooth, then select the "Wireless Controller" option listed. Once it states that your device and controller are connected, you will notice that you can use the DualShock 4 controller to navigate through the device, though, some actions are limited.
As mentioned before, not all games are compatible with third-party controllers, but many are, so head into the game's settings and look for controller options. Every game is different, but what you essentially want to look for is a way to disable the Android controls or select a third-party controller option.
Your favorite game has no built-in support for controllers? If you're rooted, use Tincore Keymapper to make your DualShock 4 controller work with it.
When you're done playing your Android games and want to play your PlayStation 4 again, simply connect the controller to the console via the mini-USB cord and press the PS button.
