When the proximity sensor is activated, it signals the iPhone to turn off the screen to conserve battery life and prevent accidental operations.
This feature is particularly useful when you want to take a quick photo without having to unlock your iPhone. By covering the camera lens, the proximity sensor is activated, and the screen goes black. This allows you to take a discreet photo without raising any suspicion, for example, in situations where photography may not be allowed or inappropriate.
In conclusion, the iPhone screen goes black when you cover the camera due to the activation of the proximity sensor. It is a built-in feature that conserves battery life and prevents accidental operations. Whether you find this feature convenient or not, it is an integral part of the iPhone’s functionality and serves various purposes for its users.

Camera Proximity Sensor and Black Screen Issue
Many iPhone users have experienced the issue of their screen going black when they cover the camera. This happens due to the camera proximity sensor, a small sensor located near the front-facing camera of the iPhone. Its main function is to detect the presence of an object near the camera and adjust the screen accordingly.
The camera proximity sensor works by emitting infrared light and then measuring the amount of light that is reflected back. When you place your hand or any other object close to the camera, it blocks the infrared light from reaching the sensor, causing it to detect the object and trigger an action. In the case of covering the camera, the sensor detects the object (your hand) and assumes that it’s near your face, which is why it automatically turns off the screen to prevent accidental touch input during a call.
While the camera proximity sensor is an essential feature that helps improve the user experience, it can sometimes cause frustration when the screen goes black unintentionally. There are several possible reasons why this may occur:
1. Dirt or debris on the sensor:
If there is dirt or debris covering the camera proximity sensor, it may interfere with its ability to function properly. Try gently cleaning the sensor with a soft, lint-free cloth to remove any dirt or debris that may be present.
2. Malfunctioning sensor:
In some cases, the camera proximity sensor may be malfunctioning, which can cause the screen to go black even when the camera is not covered. If you have tried cleaning the sensor and the issue persists, it may be necessary to have the sensor repaired or replaced by a professional.
It’s important to note that covering the camera during a call or while using certain apps is a normal behavior and is designed to prevent unintended touch input. However, if the screen goes black when the camera is not covered or if it happens frequently, it may indicate a problem with the sensor that needs to be addressed.
If you continue to experience issues with your iPhone screen going black when you cover the camera, it is recommended to contact Apple support or visit an authorized service center for further assistance.
