The Camera Control button on the iPhone 17 can do more than open the Camera app. You can set it to open Camera Code Scanner or the Magnifier. The setting lives in the Settings app, and it is simple to change.
Change Camera Control
- Open the Settings app on your iPhone.
- Scroll to Camera and tap Camera.
- Tap Camera Control.
- Choose Camera Code Scanner, Magnifier, or None.
Tapping the camera button will launch the camera app normally. In case you press the Code Scanner button, you can access a fast scanner, which reads QR codes and displays corresponding web addresses. Should you select Magnifier the button you are taken to a plain tool that assists you in magnifying small text or objects. These are steps that are outlined on Apple support pages.
In case you want the Camera Control button to appear as a physical dial, then you can leave it on Camera and swipe or press the light when the Camera app is open. That allows you to adjust zoom or exposure without using the touchscreen. The button can also be supported by third-party camera apps in order to allow more advanced apps to lock focus or adjust capture behavior.
Use Code Scanner
The Code Scanner on iPhone is fast and direct. It will open a link when it finds a QR code or show the code text if no link is present. You can also type code into the iPhone search field to launch the scanner at any time. This makes the Code Scanner useful for people who scan many codes for work or projects. Apple documents how the scanner works and how the Camera app detects QR codes automatically.
The Camera Control can be disabled in Accessibility settings in case you consider it to be too sensitive. That will prevent the button from doing any action until you turn the button on again. In case you have third-party camera software, visit its support pages to find out how it utilizes the Camera Control button and what additional features it has.
Test both Code Scanner and Magnifier in a day before you change anything. Try every one of the options to determine their compatibility with your workflow and how the phone will perform with the lock screen or Quick Note features. When using the phone, the Code Scanner can accelerate ticket inspections and access to events, and the Magnifier is useful in reading tiny fonts and labels.
Each of these alternatives is reversible and non-hazardous. In case you have a second thought, go to Settings, Camera, Camera Control, and choose another. The Camera Control provides you with the ability to control the iPhone 17 quickly to do what you need at the time.
