Xiaomi Redmi 6 Proximity Sensor Where It Is

Setting and calibrating the proximity sensor on Xiaomi devices

Each smartphone consists of dozens of parts, sensors and elements responsible for the various functions of the device. One such part is the proximity sensor. Often people are faced with a violation of its work: the sensor is buggy, does not work, or has ceased to function at all. What to do in these and other situations you will learn from this article.

What is Xiaomi proximity sensor and what is it responsible for

The proximity sensor or, as it is also called, the light sensor is responsible for approaching, or rather for turning off the screen during a telephone conversation and for adjusting the brightness level.

Sometimes the question comes: “Where is the proximity sensor?”. In fact, the word “sensor” is rather arbitrary, denoting the presence of a special sensor in the design of the device next to the front camera and the earpiece.

Disruption of this function has many inconveniences. For example, during a conversation, you can accidentally press unwanted buttons or completely reset the call. If the proximity sensor does not work, the phone, being in your pocket, may involuntarily perform any action or call someone, guided by the touch of the screen on the clothes.

Causes of Trouble

  • Incorrect operation of the device itself. Only in this case will you have to calibrate the sensor
