Samsung introduces a new GamePad controller for Android Phone but you can’t get it here yet. It is available in some European countries and Samsung did not specifically mention it will be available else where or not.
The GamePad controller has a grip that is capable of grabbing phone from 4-inch to 6.3-inch in screen size. It can be paired with NFC on selected Samsung GALAXY Android phones that is running Android 4.1 and above.
Seriously, there is not much details but I think gamers should be excited about this gadget if they are serious about playing games on mobile phones. Nothing beats the actual hardware buttons.
