On both Apple and Android phones, you can take a photo by pressing either volume button along the side of your phone. This is like a physical button on an old camera.
For people who have trouble holding their phone steady or mistakenly take multiple photos at once, using the physical button instead of the touch screen can help you hold the phone steadier and only take one photo at a time.
To use this feature, open your camera like normal, then click either the up volume or down volume button and your camera will take a picture.
