If there is something blocking the camera, such as dirt, fingerprints, or a protective case, it can prevent the camera from properly scanning the code.
If you're wondering why your phone won't read QR codes, it's worth checking if there is any debris or obstruction on the camera lens. Clearing the lens of any dirt or fingerprints can often solve the problem and allow your phone to scan QR codes again.
If you have a protective case on your phone, it's possible that the case is partially covering the camera lens and obstructing its view. Try removing the case and see if that helps your phone recognize QR codes. If it does, you may need to consider using a different case or finding one that doesn't cover the camera lens.
In addition, make sure that you are holding the phone at the correct distance and angle when scanning QR codes. If the camera is too far or too close to the code, it may not be able to focus properly and read the information. Experiment with different distances and angles to find the optimal position for scanning QR codes.
In summary, an obstructed camera can be one of the reasons why your phone can't read QR codes. Check for any dirt, fingerprints, or obstructions on the camera lens and make sure you're holding the phone correctly. By doing so, you should be able to overcome this issue and start scanning QR codes again.
