But before we go ahead let us know what is a proximity sensor on smartphones and the reasons why your Android proximity sensor stops working.

What is Proximity Sensor on Smartphones?

The proximity sensor on smartphones is a small component typically located near the earpiece of the device. It plays a crucial role in detecting the presence of nearby objects, such as your face, and enables certain functionalities and features.

The proximity sensor uses infrared or optical technology to determine the distance between the sensor itself and an object in its proximity. It emits infrared light or beams and measures the time it takes for the beams to bounce back after hitting an object. By analyzing the reflected beams, the sensor can identify whether an object is close or far away.

When it comes to smartphones, the proximity sensor primarily serves two purposes:

1. Screen On/Off during Calls: One of the main functions of the proximity sensor is to turn off the screen when you hold the phone to your ear during a call. By detecting the proximity of your face, the sensor signals the phone to disable the touchscreen temporarily. This feature prevents accidental touches and button presses during a call.

2. Auto-Brightness Adjustment: Some smartphones utilize the proximity sensor to adjust the screen brightness automatically based on the surrounding light conditions. The sensor detects the ambient light intensity and adjusts the screen brightness accordingly, providing optimal visibility and conserving battery life.

Reasons Why Your Android Proximity Sensor Stops Working

 There are several possible reasons why a proximity sensor may stop working or malfunction in a smartphone. Let’s explore some common causes:

Software Glitches: Like any other software component, the proximity sensor functionality can be affected by software glitches or bugs. This can occur due to system updates, incompatible apps, or conflicts with other software components.

Improper Calibration: Sometimes, the proximity sensor may require calibration to work accurately. If the sensor is not properly calibrated, it can result in inaccurate proximity detection or failure to activate at the right distances. Calibration issues can occur due to software updates, system changes, or even manufacturing inconsistencies.

Hardware Damage: Physical damage to the proximity sensor or its related components can cause it to stop working. Dropping the phone, excessive pressure, or water damage can affect the sensor’s performance.

Hardware Manufacturing Defects: In rare cases, a proximity sensor malfunction may be due to a manufacturing defect. This can occur if the sensor component is faulty or improperly installed during the manufacturing process.

Now, that you are well acquainted with all the possible reasons let’s jump on fixing this problem.
