17 Take Pictures With Your Volume Buttons
The native iPhone Camera app is pretty straightforward. You just line up a picture and hit the shutter button to snap an image. But there’s actually an easier way to shoot photos on your iPhone: just use your volume buttons as the shutter.
Clicking either the Volume Up or Volume Down button will take a picture on the native Camera app. And this clever shortcut allows for easy access when you’re shooting in landscape mode (which is recommended for the vast majority of photos). Just think of it as the analog shutter button on your old point-and-shoot camera.
