🔎 Troubleshooting Common Issues
| What might be wrong | How to fix it |
|---|---|
| Your mobile camera lens is dirty or smudged | Clean your phone’s camera lens with a soft, lint-free cloth to remove any fingerprints, dust, or smudges that may be blocking the camera’s view. |
| The primary device screen brightness is too low | Increase the brightness on your laptop or desktop screen where the QR code is displayed to make it easier for your mobile camera to detect and read the code. |
| Poor lighting conditions in your environment | Ensure there is adequate lighting in your room so your mobile camera can clearly capture the QR code displayed on your primary device screen. |
| QR code scanning feature is disabled in your camera app | Open your mobile camera settings and enable the “Scan QR codes” option if it’s turned off. |
| The mobile camera is not focused properly | Hold your phone steady at an appropriate distance (6-8 inches) from the screen and allow the camera to auto-focus on the QR code. |
| Other apps are using your mobile camera | Close all background apps that might be accessing your camera (such as Zoom, WhatsApp, or other video calling apps) before attempting to scan the QR code. |
| QR code image is damaged, blurred, or obstructed | Make sure nothing is covering or blocking the QR code on your primary device screen, and that the display is clear without any cracks or damage. |
| Your mobile device doesn’t have a built-in QR scanner | If your phone’s default camera doesn’t support QR scanning, download and install a third-party QR code scanner app from your device’s app store |
