edge of the phone will return you to the top of the list. Scrolling on Android can be pretty fast, but the simple double-tap seems like a great solution. And, last was a gesture whereby placing your hand over the device will pause video that you're watching, including video in pop-up mode.The first gesture could be useful, but it didn't really work so well. By waving your hand across the screen, the phone will take a screenshot. Interestingly, although this gesture didn't work the first couple times, it did make the screen slide, so there could very well be touch-free gestures for navigation available as well. The second gesture shown is by far the most useful of the bunch. The video shows that if you are scrolling down a long list of items, like your Twitter feed perhaps, a quick double-tap on the top
Definitely nice to see Samsung thinking out of the box with gesture controls.
