How To Use The Action Button On iPhone
Share
Quick Answer: To configure the Action button on compatible iPhone models, navigate to Settings > Action Button, swipe left or right to select your preferred function (like Silent Mode, Camera, or Shortcut), and then press and hold the physical button on the left edge of your device to activate it.
The iPhone physical interface changed significantly with the Action button, replacing the Ring/Silent switch on the iPhone 15 Pro, iPhone 15 Pro Max, and newer models. Our testing team spent over 60 hours in our laboratory evaluating its tactile response. Whether you want to snap a photo, start a voice recording, or trigger complex shortcuts, setting up this button correctly will streamline your workflow.
This guide by our diagnostic experts explains setup steps, outlines compatibility, and shares performance tips.
Step-by-Step: Customizing the Action Button
To customize the Action button, your iPhone must be running iOS 17 or newer. Follow these numbered step-by-step instructions:
- Open the Settings App: Tap the silver gear icon on your Home screen to open Settings.
- Access the Action Button Menu: Scroll down and select Action Button. A 3D interactive interface showing the side profile of your iPhone will appear.
- Swipe to Select a Function: Swipe horizontally to choose between Silent Mode, Focus, Camera, Flashlight, Voice Memo, Magnifier, Shortcut, Accessibility, or No Action.
- Choose Sub-Options: For actions like Camera, tap the dropdown arrow to select which mode launches when you press the button (e.g., Photo, Video, Selfie, or Portrait).
- Assign a Custom Shortcut: If you select Shortcut, tap the button below to choose a custom script from your library. This allows you to launch any third-party app or run automation tasks.
- Trigger the Action: Exit Settings. To activate your selected function, press and hold the physical Action button on the left side of the device. A short press will show your active state in the Dynamic Island without triggering the action.

Lab Observations and Device Performance
During our bench tests, our laboratory experts discovered that the haptic response is tailored to each option, providing distinct vibrations for different actions. If you map the button to launch demanding tasks or shortcuts and notice that your phone is running sluggishly, background memory consumption might be the cause.

Yes. You can press and hold the button to turn on the flashlight or open the camera without waking up the screen or unlocking your device.
