Wish you would of turned on the tablet and tried out the "smart" element since it has been claimed to not work. With a real magnet you can find the "smart" sensor in the lower left corner.
This case doesn't have the smart element, so there was nothing to try from that perspective. It doesn't work. I do wish that the person who did the video had had the tablet on so people could see that the cover activates the touch sensor on the screen.
