The Proximity Sensor is an important component of the iPhone. It helps detect the proximity of your face during calls and turns off the display to prevent any unintentional touch inputs when on calls.

To resolve the issue, clean the area around the proximity sensor and ensure no obstructions. You can see it in the top center of your iPhone's front-facing camera.
