I am noticing two dots on the right side of the selfie camera on the lock screen. They appear only for a second. I'm noticing it today only. It appears when the mobile is locked. I'm not able to take a screenshot of that to post here. Can anyone tell me about this?
I'm using s21 fe sd 888.

It is the proximity sensor.
A proximity sensor in a mobile device detects the presence of nearby objects without physical contact. It's usually located under the display.

They are proximity sensors which blink when they sense something close to the phone. Nothing to be worried about.

The black dots are visual indicators that the proximity sensor is actively working. They are not a display issue.
