Gestures vs. buttons: what actually changes
Gesture navigation frees up the bottom of the screen for more usable space, but the back gesture in particular can feel unfamiliar at first. Since you can switch back to buttons at any time from the same settings menu, there's no harm in giving it a try.
It gets easier with a few days of use
Most of the friction with gesture navigation comes from muscle memory built around physical or on-screen buttons -- most people find the back and home swipes start feeling automatic within a few days, and adjusting the edge sensitivity clears up the majority of misfires early on.
Frequently Asked Questions
How do I switch between apps with gesture navigation?
Swipe left or right along the bottom of the screen to quickly cycle through your recently used apps.
My back gesture keeps conflicting with something else on screen.
In some apps, an edge-swipe menu can overlap with the back gesture zone -- reducing the edge recognition width in the navigation settings usually fixes this.
