Make sure you're in Photo mode

When the QR code scanner is enabled, check if you're in Photo mode while trying to scan the code. The code scanner won't work if you're in Portrait, Video, or another camera mode, as the feature only works with the Photo mode.

Scan in Photo mode

Your iPhone camera doesn't have a separate QR code scanner mode you can turn on. The built-in code scanner will detect the QR code and open it when you're camera is in the Photo mode.

When the QR code is detected yellow border will appear and show you where it will take you. Usually, it's a website.

Make sure the camera is pointed correctly

A lot of the time, there are no issues with the QR code scanner. All you need to do is make sure you're pointing the camera correctly, and the code is clearly visible. If it's dark, small, blurred, or a part of it is missing, your iPhone won't be able to scan it.

If the QR code is on a screen, try to increase the screen brightness or zoom in to make it bigger. If it's on paper, try to scan it from different positions. If possible to move it, place it in a brighter place like near a window.

Scan code corretly

When the code is detected, you should see a yellow border and a QR code scan icon at the bottom right corner of the camera.

1. Open the Settings app.
2. Tap on "Control Center".
3. Scroll down and locate the "Code Scanner" feature and next to it, tap on the green plus button.
