This can be helpful if a lot of your apps still have sidebars that are swiped open from the left. This will let you, say, decrease the sensitivity of the back gesture from the left edge and increase the sensitivity of the back gesture from the right edge.

In Android 11 DP3, you can independently adjust the sensitivity for both sides of the screen. However, these sensitivity options applied to both sides of the display. In case you find it difficult or too easy to do the back gesture, you can increase or decrease the sensitivity, which simply shifts the starting point of the back gesture.

To replace the back button, Google added inward swipe gestures from both the left and right sides of the screen. Android 10 introduced full-screen gesture navigation with the pill bar at the bottom.
