However, this point is not a technical failure, but rather is related to one of the basic functions built into the phone, which is designed to enhance the user experience and protect the user’s privacy.
Technical reports explain that this point is not a defect, but rather a visual indicator resulting from the Proximity Sensor present in the phone.
This sensor is responsible for knowing how close the phone is to the face during calls, and automatically turns off the screen when the phone is placed on the ear to prevent unintentional touches.
According to recent technical explanations, the sensor works by emitting and receiving infrared rays to measure the distance between the phone and the body, which may sometimes appear as a small flashing dot on the screen in modern devices. (Erm News)
