Telegram Cannot Scan QR Codes
If you've found the scanning feature but can't successfully scan QR codes, it might be due to the following reasons:
Camera Permission Issues
Symptom: Camera doesn't start or shows a black screen when opening the scan feature.
Solution:
- Make sure you've granted Telegram camera permissions:

- Android: Settings → Apps → Telegram → Permissions → Camera
- If already authorized but still not working, try restarting your phone
- If the problem persists, try uninstalling and reinstalling the Telegram app

Symptom: Camera starts but can't focus or the image is blurry.
Solution:
- Ensure the camera lens is clean, free of dust or fingerprints

- If your device has multiple cameras, try switching to another camera
Insufficient Lighting
Symptom: Camera view is too dark to clearly identify the QR code.
Solution:
- Move to a well-lit environment
