Why is the QR code not scanning? - Talview Docs

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.

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.
