Black ring around camera.

[sayoush_stark]

There's a black ring around camera app throughout the system. During this time of pandemic a webcam is a must but the black ring makes the experience very bad. I have shown the problem in the image. Please someone help me solve this problem.

I solved the problem. It wasn't a software issue. It seems the screen got little lose form the chasis. I pressed it a little and now the camera is as good as new. The curvature must be from the display.
