Unlike any other Android phone, the S22 loaded up with three navigation buttons. If you wish to switch to Android gestures, then swipe down from top to open
settings (that little cog in the top right), display > navigation bar. It is strange for the feature to appear in this place.
Here you can either change the order or opt for 'Swipe gestures.
You can customize the order of navigation buttons if you are sticking with onscreen controls.
The wallpaper can be edited by pressing the long-press button on any screen. You can also change the wallpaper's style, themes or widgets.
This area also allows you to add screens (swipe on a new page, hit the huge + in the circle),
or remove complete screens (hitt the trashcan icon uptop), which will prompt you to confirm screen removal.
