Here’s a clear, step‑by‑step guide on how to turn off a Samsung phone , plus extra methods if buttons or screen act weird.

Basic method (most Samsung phones)

1. Using the Side key (power button)

On most recent Galaxy phones (S21, S22, S23, S24, A‑series, etc.) the power function is on the Side key.

  1. Press and hold the Side key and Volume down together for a few seconds.
  2. A menu should appear with options like:
    • Power off
    • Restart
    • Emergency mode
  3. Tap Power off , then confirm Power off again if asked.

If your phone is older, you might only need to press and hold the power button (no volume button) until the power menu appears, then choose Power off.

Turning off from the Quick Panel (no buttons)

If you don’t want to use hardware buttons:

  1. Unlock your phone.
  2. Swipe down from the top of the screen with two fingers to fully open Quick Settings.
  3. Look for a power icon (usually near the top-right, next to the settings/gear icon).
  4. Tap the power icon.
  5. Choose Power off , then confirm if needed.

This method is handy if your Side key has been remapped or is unreliable.

Using Bixby voice (with voice commands)

If Bixby is enabled on your Samsung phone:

  1. Activate Bixby:
    • Either press and hold the Side key (if set to Bixby), or
    • Say “Hi Bixby” if voice wake is on.
  2. Say: “Turn off the phone.”
  3. Confirm when Bixby asks (e.g., “Yes” or tap Power off on screen).

This can be useful if you can’t easily press buttons or reach the menus.

If the phone is frozen or unresponsive

If the touch screen doesn’t react, you might need a forced shutdown/restart.

1. Soft reset / forced restart

  1. Press and hold Power (Side key) + Volume down at the same time.
  2. Keep holding for around 10–20 seconds until the screen goes black.
  3. If it restarts and you want it to stay off, you can:
    • Let it restart, then immediately use the normal Power off menu once it’s responsive, or
    • On some models, keep holding the buttons a bit longer to force it fully off (behavior varies by model).

Note: On most modern Samsung phones with non‑removable batteries, this is the main way to simulate pulling the battery.

Special cases: very new, very old, or button‑customized phones

Samsung keeps tweaking how the Side key works, so a couple of extra checks:

  • If pressing and holding the Side key opens Bixby instead of the power menu :
    • Go to Settings → Advanced features → Side key.
    • Under Press and hold , select Power off menu instead of Bixby.
    • After that, press and hold the Side key to get the power menu.
  • On older Galaxy phones (with a dedicated power button and sometimes a Home button):
    • Just press and hold the power button until the menu appears, then tap Power off.
  • On some foldable or special models, the Side key location may differ (e.g., combined with fingerprint sensor), but the method is the same: long press the Side key / Side key + Volume down to reach the power menu.

Quick mini‑guide (copy‑paste friendly)

  • Most recent Samsung phones:
    • Hold Side key + Volume down → tap Power off → confirm.
  • Via Quick Settings:
    • Swipe down twice → tap power icon → Power off → confirm.
  • Via Bixby:
    • Activate Bixby → say “Turn off the phone” → confirm.
  • If frozen:
    • Hold Side key + Volume down for 10–20 seconds → screen goes black → device restarts or shuts down.

Tiny storytelling example

Imagine you just got a new Galaxy S‑series phone and you go to turn it off like your old one—long‑pressing the side button—but Bixby suddenly pops up instead of a power menu. For a lot of people, that’s when the “how to turn off Samsung phone” searches start. Once you know to either use Side key + Volume down or switch the Side key behavior in Advanced features , the phone instantly feels more “normal” again, and shutting it down becomes a two‑second habit instead of a mini‑mystery.
