Most people use their phone’s volume buttons only to make calls, videos, or music louder or quieter, but on many modern smartphones they can perform additional functions. One of the most useful is controlling the camera shutter. On many iPhone models and Android phones, pressing either volume button while the camera is open can capture a photo, making it easier to take pictures without reaching for the on-screen shutter button. Depending on the device and camera application, the buttons may also support functions such as starting or stopping video recording, taking burst photos, or controlling zoom. The exact behavior varies by manufacturer, operating system, and camera settings, so a feature that works on one phone may not work on another. Checking your phone’s official user guide is the safest way to confirm which shortcuts are supported.
Volume buttons can also become useful accessibility and emergency shortcuts. On some smartphones, combinations involving the volume buttons and the power or side button can activate emergency features or other system functions. For example, Apple’s Emergency SOS feature can be activated on supported iPhones by pressing and holding the side button together with a volume button, while Android manufacturers may use different button combinations for emergency or accessibility functions.

These shortcuts can save time when your hands are occupied, when you are taking a group photo, or when reaching the screen is inconvenient. Because button combinations can differ significantly between devices, avoid assuming that a particular shortcut is universal.
There is also a practical reason to learn these functions: physical buttons can sometimes make everyday phone use faster and more convenient. Instead of tapping the screen repeatedly, you may be able to use a volume key to take a picture, adjust audio, or perform another supported action. If you have a newer phone, open the Camera settings and Accessibility settings to see which button-based controls are available. Avoid downloading unknown apps that promise secret button functions, particularly if they request unnecessary permissions.

Button shortcuts vary by phone model, operating system, software version, and application. Always verify available functions through your device manufacturer’s official documentation and use emergency shortcuts only when appropriate.
