# Why is the QR code not scanning?

During attendee onboarding, you may need to scan a QR code displayed on your **laptop or desktop** (primary device), to connect your **mobile phone** as a secondary camera.

This article helps attendees resolve QR code scanning issues when setting up their secondary device.

## 🔎 Troubleshooting Common Issues

| What might be wrong | How to fix it |
| :- | :- |
| Mobile camera lens is dirty or smudged | Clean the camera lens using a soft, lint-free cloth to remove dust or fingerprints. |
| Primary device screen brightness is too low | Increase the brightness on your laptop or desktop so the QR code is clearly visible. |
| Poor lighting in your environment | Ensure the room is well lit so your mobile camera can capture the QR code clearly. |
| QR scanning is disabled in the camera app | Open your phone’s camera settings and enable the QR code scanning option. |
| Mobile camera is not focusing | Hold your phone steady about 6–8 inches from the screen and allow it to auto-focus. |
| Another app is using the mobile camera | Close background apps that may be accessing the camera (for example, video calling apps). |
| QR code is blurred or obstructed | Make sure the QR code is fully visible, unobstructed, and the screen is not damaged. |
| Device does not support built-in QR scanning | Install a trusted third-party QR code scanner app from your app store. |

> [!TIP]
>
> **Additional Tips:**
>
> * Restart your mobile device if the issue persists, as this can resolve temporary software glitches affecting the camera functionality.
> * Use landscape mode when positioning your phone after scanning to provide a wider viewing angle for the secondary camera feed.
> * If the issue continues after troubleshooting, try switching to a different mobile device and attempt the QR code scan again to determine if the problem is device specific.
