The Camera Control button is currently unique to the iPhone 16 lineup. Last updated 11 hours ago. Unless you've gone looking in System Settings, you may not be aware that the Camera Control button on the iPhone 16 models can be set to do other functions besides set up and take a picture. Here's how to change it.
By default, pressing the Camera Control button launches the Camera app on the iPhone 16, iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max. Once open, pressing the button again will take a picture, or pressing and holding will shoot video. A light press on the Camera Control button once the Camera app is open gives users a haptic click and the ability to adjust settings like zoom level or exposure. It operates sort of like the dials or on-screen controls in DSLR cameras.
Some users, however, will prefer to use the Camera app's on-screen menus rather than the button. System Settings will let you reprogram the Camera Control button to instead use it to launch the Magnifier app, or to launch a hidden Code Scanner app. Here's how to do it.
The Camera app can, by default, read QR codes when the camera is pointed at one, and reveals the destination URL of the QR code without having to snap a picture of it. However, if you need to scan a lot of QR codes for your work or project, you can reprogram the Camera Control button to instead launch a secret, dedicated Code Scanner utility that is already on your device.
