A YouTube user has posted a video of what he claims is
The video matches images that leaked yesterday on a Chinese forum. It also seems to match Samsung's official teaser image of the Galaxy S4. We first saw the video on SammyHub.
Don't forget: Samsung will officially announce the Galaxy S4 at a big press event March 14.
Also, notice how the video promo for Apple's iPad Mini is playing in the background. Kind of funny.
