There is an issue with the proximity sensor on my Samsung S23 smartphone. The sensor is constantly blinking, causing a black smudge to appear on the screen below the camera. I have already disabled accidental touch protection and sensitive touch.
Please advise on the appropriate steps to resolve this issue.
It seems like this might be a display issue. I recommend visiting a Samsung service center to get it checked.

The smudge issue is not related to the display. After disabling the accidental touch and smart awake features, the smudge gradually faded away. As of today, it is barely noticeable on the screen.
