Samsung Side Button: Change What a Double Press Opens

Change the Galaxy power button’s double-press action in Settings. Samsung calls it the Side button on current devices, while older menus may say Side key.
Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

To change what a Samsung Galaxy power button does when you double-press it, open Settings > Advanced features > Side button > Double press, then choose an app or feature. Samsung calls the power button the Side button in its current instructions; older phones or software may label it the Side key.

Change the double-press shortcut

  1. Open Settings.
  2. Tap Advanced features.
  3. Tap Side button.
  4. Tap Double press.
  5. Select the app or feature you want to open when you double-press the button. If an app has a gear icon beside it, tap the icon to choose from its supported in-app actions.

Samsung says Camera is the default double-press action on devices covered by its current guide, but you can reassign it. The guide gives examples such as Samsung Wallet, Flashlight, Magnifier, Voice Recorder, Samsung Notes, Samsung Capture, and Modes and Routines. Depending on the app, a gear icon may offer a more specific shortcut, such as opening the selfie camera, starting a recording, or opening a particular mode. These are examples, not options guaranteed to appear on every Galaxy device. Samsung’s current Side button guide was updated on 19 August 2025.

If your settings use different names

Menu labels and available assignments depend on the Galaxy model, software version, region, and carrier. If you do not see Side button, use the Settings search field to look for “Side button” or “Side key.” Follow the options shown on your own phone rather than assuming another model’s menu will match.

Older Side key menus

On some older devices, the setting is called Side key. Samsung’s older instructions describe the path as Settings > Advanced features > Side key > Double press > Quick launch camera for devices with a Side key. That older menu also documents choices such as opening Bixby or an app. Samsung’s Camera guide describes these earlier labels.

Phones with a separate Power key

Some older Galaxy phones have a separate Power key rather than the Side key described in those instructions. Samsung’s older Camera guide places Quick Launch in the Camera app’s settings for that design, rather than in the Side key menu. The precise steps depend on the model and software version.

What the other button presses do

The double press is separate from the button’s single-press and long-press behavior. Samsung’s current guide says a single press wakes or locks the screen and a long press launches Gemini on the current devices it covers; defaults can differ by device. It also describes holding the Side button and Volume Down together for power-off or Emergency SOS functions on covered devices. Check Samsung’s guide for its current device coverage.
