- Try taking a photo via WhatsApp or Telegram.
- Check if the image appears in mode AR-masks if available).

| Camera works, but image blurred/with artifacts | Lens contamination or module damage | Cleaning the lens or diagnostics in the service |
| The camera app immediately closes. | Memory deficiency or conflict with other processes | RAM cleaning or safe mode |
