For example, it’s possible to change the function of the side button so that it brings up the Power menu when you press and hold.
Here’s how you can do that:

Now, when you press and hold the side button, your S20 will open the power menu instead of opening Bixby, allowing you to turn off the phone or reboot.
Tap the power icon in the top right (located next to the settings or gear icon). It will open the Power menu.
Tap Side Key Settings at the bottom.
