This article explains how to turn off the Samsung Galaxy S20 and later phones, including the Galaxy S21.

Where Is the Off Button on the Samsung S20?

Earlier models—like the Galaxy Note 9—have a dedicated power button, but that's no longer the case. Samsung decided not to include a dedicated power button on the Galaxy S20, which has also carried over to the Galaxy S21. In short, there is no dedicated power button on the S20.

You now use one of two methods to power down the S20. A shortcut involves pressing a combination of hardware buttons or using the software interface to shut down and restart the phone.

Even though there’s no dedicated power button on your Galaxy S20, you can still press and hold the side button (Bixby button) to turn on your device. You can also turn the screen back on by pressing the button once.

How to Change the Side Button Function on a Samsung S20

By default, when you press and hold the side button on a Galaxy S20, it will bring up Bixby, Samsung’s voice assistant. If you don’t use Bixby, you can change the button's function in the Samsung settings menu. 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:

  1. Swipe down to open the quick settings panel. Then, swipe down again to open the full-screen panel.

  2. Tap the power icon in the top right (located next to the settings or gear icon). It will open the Power menu.

  3. Tap Side Key Settings at the bottom.

    Swipe down > Power > Side key settings on Samsung S20
  4. Under the Press and Hold section, choose Power Off Menu.
