Games that support a game controller, can be very comfortable playing it. I have the following games thus played: Dead Trigger2, Asphalt 8 Airborne, Shadow Gun. The buttons can be configured depending on the game itself.
In the center of the controller there is a play button. About this starts a Samsung own tile view of the available in the Samsung Store games with gamepad support. To use the button and the tile display, Samsung requires the installation of the "Samsung Console". Selling / DOWNLOADED Only in Samsung Store Games can then start on that tile view.
Should you games bought the full version in Google Store, then these do not integrate in the tile display / start from there.
The gamepad connects via Bluetooth and is quickly and easily coupled - with several devices.
For me, the acquisition was worth.
