When you think of your phone’s volume controls, you probably only consider one thing: turning the sound up or down. However, by 2025, these little side keys have become gates to a plethora of secret features—some useful, some lifesaving, and some simply entertaining. Whether you own an iPhone or an Android device, the simple volume button has expanded well beyond its initial purpose.

One of the most basic yet underappreciated features is using the volume button as a camera shutter. Instead than messing with on-screen buttons, you can take a photo or start recording video with a single click. This is especially useful for selfies and holding the phone at an awkward angle. Many Android devices also allow you to set long presses for burst shots.
