How to Turn Off a Samsung Phone: Button, Quick Settings, and Bixby Methods

Use Side + Volume Down to open the power menu on many Samsung Galaxy phones, or shut down through Quick Settings. Learn the Bixby and frozen-phone options too.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

On many recent Samsung Galaxy phones, press and hold the Side button and Volume Down together until the power menu appears. Tap Power off, then tap it again to confirm. If the Side button opens Bixby or another assistant, use Quick Settings instead.

Turn off your Samsung phone with the buttons

  1. With the phone on, press and hold the Side button and Volume Down button at the same time for a few seconds.
  2. When the power menu appears, tap Power off.
  3. Tap Power off again to confirm.

This sequence applies to many Galaxy models with a Side button. Button names, layouts, and menus differ on some older phones and tablets. Samsung notes that screens and settings can vary by model, software version, and wireless provider. See Samsung Canada’s power on/off instructions for its model-specific guidance.

Use Quick Settings if the buttons do not open the power menu

  1. Swipe down from the top of the screen to open Quick Settings. On some devices, swipe down with two fingers to open the full panel.
  2. Tap the Power icon.
  3. Tap Power off, then confirm by tapping Power off again.

This on-screen route avoids the Side button’s long-press assignment, but it requires a responsive touchscreen. The icon’s location and panel layout can vary by model and software.

Why holding the Side button may open Bixby

On many newer Galaxy phones, the Side button combines functions that older models assigned to separate Power and Bixby buttons. Its long press may be set to open Bixby or another assistant rather than the power menu. Try Side + Volume Down or Quick Settings to shut down.

Ask Bixby to turn off the phone

If Bixby Voice is set up and available on your device, press and hold the Side button to summon Bixby, then say, “Turn off the phone.” This voice method depends on Bixby Voice setup and the device’s assistant configuration. Samsung describes this option in its Galaxy power-off guidance.

If the phone is frozen

A frozen phone may not respond to the normal shutdown menu. Press and hold the Power/Side button and Volume Down simultaneously until the phone shuts down and reboots. Samsung says this forced restart can take up to 60 seconds and simulates removing the battery; it is not a normal power-off because the phone restarts. Use it for an unresponsive device. If it still will not turn off, Samsung advises requesting service; see its troubleshooting guidance for a Galaxy phone or tablet that will not turn off.
