Almost any shooter can be played better and more comfortably with a controller than with a touch screen. However, you can still improve the experience if you duplicate the screen of your Android to a TV. Finally, remember that once you have synchronized the controller with your smartphone, it will be unsynchronized from any other device or console, so you should sync it again to continue using it on other devices as well.
