I disabled Samsung's default gestures and remapped them to shortcuts that actually work

Samsung gives you a massive display, but your thumb barely uses any of it. Swipe down for notifications, swipe up for apps, and that's about it. The rest of the screen just sits there while you shift your grip or reach for a second hand every time you need something beyond those two moves. I spent over a year assuming Samsung had already figured out the best way to get around a phone this size. Then I found a module buried inside their own customization software that turned all that wasted glass into something I actually control.
