How to Fix the Proximity Sensor Error on Smartphones

This practical guide walks through how to fix the proximity sensor error on smartphones, explains the main requirements, and highlights common issues that may appear along the way.

1. How to recognize a broken phone's proximity sensor

Proximity sensor is a type of sensor placed on the front of the phone that can be easily seen. On the iPhone it's usually a circular dot next to the front camera.

When you put the phone to your ear to listen to a call, if the proximity sensor is still working properly, the phone screen will automatically turn off to save battery life and avoid you pressing the wrong touch buttons.

When the proximity sensor is damaged, the screen will stay on continuously and you may accidentally press the touch buttons while on the phone, and also drain the phone's battery.

2. Causes of Proximity Sensor Damage

Using a screen protector that is too thick will interfere with the sensing function of the proximity sensor, making the sensor unable to work.
