Your phone’s volume buttons can do much more than adjust sound, although the exact shortcuts depend on the device, operating system and settings.
One of the most useful functions is taking a screenshot. On most Android phones, press the power and volume-down buttons together. On iPhones with Face ID, press the side button and volume-up button simultaneously.
When the camera is open, many phones let you press either volume button to take a photo. This can feel steadier than tapping the screen, especially when taking selfies or holding the phone horizontally.
The buttons can also control media without unlocking the phone. They adjust music, video and call volume, while some apps or devices allow additional actions such as changing tracks.
Accessibility shortcuts are another overlooked feature. On Android, holding both volume buttons can launch a selected accessibility tool, such as TalkBack, depending on your settings. The buttons may also be assigned as controls through Switch Access.
Volume buttons are sometimes involved in emergency features and forced restarts, but the combinations vary considerably. Avoid experimenting blindly because some combinations may trigger an emergency call.
Finally, when a physical button becomes difficult to use, both iPhone and Android offer on-screen accessibility controls that can replace volume and other hardware actions.
