Step up your Galaxy S10 or Note 9 nav gestures game with Samsung's One Hand Operation+
That's exactly what the new One UI does - its gesture navigation option replaces the bottom strip with three even-spaced "pills" for home, back and recent apps, or you can hide those altogether, and only swipe by muscle memory. Unfortunately, except being more aesthetically pleasing by doing away with the navigational strip, these gestures add no value to the navigational ergonomics, as you have to stretch even further down with your thumb to execute.
Enter Samsung's Good Lock project that lets you sideload features and options to the interface, and the latest installment that Samsung pushed to the Play Store allows you to enrich the Galaxy S10 or S9 gesture systems.
Dubbed One Hand Operation +, the app can assign side-swiping gestures to do a variety of things, including to serve as your back key. Not only that, but you can swipe straight, diagonally, or do a long swipe, and each of these gestures will do a new trick, for one complete navigational experience right under your thumbs. No stretching.
