  5. Hi,
    My camera view is black but the camera still working fine. Only thing that you cant see the picture on your phone screen. So you have to assume what you take. However, when login using face detection, I can see myself. Only when you select the camera apps, you get this problem.
    Let me know if you can fix the problem. Other than this, it works well. thank you.
