Troubleshooting Steps:
Check Lighting and Distance: Ensure the QR code is well-lit and that you're at an appropriate distance from it for your camera to focus.
Clean the Camera Lens: A dirty or smudged lens can interfere with scanning. Use a soft cloth to clean it.
Adjust Camera Settings: If your camera app allows, try adjusting focus, exposure, or resolution settings.
Verify QR Code Integrity: Examine the QR code for damage or dirt. If it's damaged, it may not scan.
Update Software: Ensure your camera app and operating system are up-to-date.
Check QR Code Scanning Feature: On some devices, you may need to enable QR code scanning in your camera settings.
Restart Your Device: Sometimes, a simple restart can resolve temporary software glitches.
Try a Different QR Scanner App: If the built-in scanner isn't working, try a third-party app.
Consider Google Lens: Google Lens can also be used to scan QR codes. Open the Google app, tap the Google Lens icon, and point your camera at the QR code.
Test with a Different QR Code: If you suspect the issue is with the QR code itself, try scanning a different one to see if it works.
Reset Camera App: If all else fails, consider resetting your camera app to its default settings.
