Every time Samsung drops a new flagship smartphone, the company seems to go that extra mile in ensuring that it packs some dazzling new features to entice the consumer market once more. In the case of the latest and greatest Galaxy S4, the South Korean outfit introduced Air Gesture, a smart little implementation which allows certain features to be controlled using basic hand movements above the device. Now, thanks to the great minds over at XDA-Developers, this kind of thing can be performed on a number of devices. Air Swiper is the name, and although, at this early stage, it’s by no means without its flaws, it’s definitely worth giving a shot.
