How to fix iPhone error that cannot scan QR code

Check if the QR code scanning feature is enabled

Usually, pointing your iPhone’s camera at the QR code will do the trick. However, if that doesn’t work, it’s possible that people accidentally turned off the QR code scanning feature in the Camera app. Here’s how to enable QR code scanning on iPhone.

Step 1: Open the application Setting on iPhone, then scroll down and tap Camera.

Step 2: Turn on feature Scan QR code.

Make sure the camera is in Photo mode

Scanning QR codes on iPhone only works when the camera is in mode Image. If you mistakenly switch to Video, Portrait, Panorama or any other camera mode, QR code scanning may not work i. So, swipe left or right in the Camera app to switch back to Photo mode. Then, point the camera at the QR code and try scanning again.

Position the camera properly when scanning

For fast and successful scanning, make sure the QR code is placed in the camera frame. Avoid scanning at steep angles and try to keep the QR code parallel to the device. Also, make sure the QR code is not wrinkled, obscured in any way as this can prevent a successful scan.

Move to better lighting

Good lighting is essential for every camera function, and QR code scanning is no exception. A well-lit environment helps the camera identify and read QR codes more easily. If you’re in a dimly lit room or area, move to a brighter place or shine some light on the QR code to improve visibility.

Clean the camera lens

A smudged or dirty lens can make it difficult for the camera to read the QR code. So, if you’re still having trouble scanning the QR code, gently wipe the camera lens with a soft, lint-free cloth to ensure it’s clean. Avoid using hard or abrasive materials that may scratch the lens. If necessary, lightly dampen the cloth with water to remove stubborn stains.

Add Code Scanner to Control Center

If you’re still having trouble using the camera app to scan QR codes, users can add Code Scanner directly to Control Center for easy access. This integration works separately from the Camera app and helps avoid problems you might encounter when using Camera.

Step 1: Open the application Settingscroll down and tap Control center.

Step 2: Click plus button (+) next to Code scanner in section Other controls to add it to Control Center.

Step 3: Now, open it Control centerthen tap Code Scanner icon to scan the QR code. When scanning in dark or dimly lit areas, touch flashlight icon at the bottom of the screen to turn on your iPhone’s camera flash.

Relaunch the Camera app

Sometimes, software glitches can cause the camera to malfunction when scanning a QR. The quickest fix for this is to simply close the Camera app and relaunch it. To do this, swipe up from the bottom of the screen, then swipe up on the Camera app to close it. Wait a few seconds, then reopen the Camera app and try scanning the QR code again.

Restart your iPhone

If the above methods still don’t work, restarting the device, although simple, may be helpful. Occasionally, minor system glitches can cause certain features, like QR code scanning, to malfunction. Restarting your iPhone can eliminate these glitches and get everything running smoothly again.

However, the iPhone does not have a restart option, so users will have to manually turn the device off and then turn it back on. Luckily, people can perform a manual restart even if the iPhone’s buttons are broken.

Update iPhone software

Apple periodically releases software updates, including fixes that can fix any operating system glitches. Outdated iOS versions may cause problems with QR code scanning, and an update will fix this issue.

To update iPhone, go to Setting > General settings > Software updates to see if there are any updates. If a new iOS version is available, tap Download and install. Make sure you’re connected to a strong Wi-Fi network and that your iPhone is fully charged before starting the update.

Use a third-party QR code scanning app

If the iPhone’s built-in QR code scanning feature is still not working after trying all of these fixes, users should consider downloading a third-party QR code scanning app from the App Store. Many options, both free and paid, offer more capabilities than the device’s built-in QR scanning feature.
