Samsung just officially unveiled its latest flagship smartphone, the Galaxy S 4
, and revealed the existence of this adorable little prototype wireless mobile controller. Communicating with the phone via bluetooth, the pad has an adjustable sliding cradle as well as four familiar-looking face buttons.
The controller runs on triple-A batteries and interfaces with a pretty slick looking arcade app, as demonstrated by the above hands-on video from our friends over at Engadget
. Expected at retail sometime this summer, Samsung's prototype has yet to earn itself an official name or price point. The Galaxy 4 S, meanwhile, will be available sometime near the end of April.
