How to adjust the sensitivity of Xiaomi mix4 distance sensor

Xiaomi mix distance sensor first opens the mobile phone settings to find my device, then returns to check all the parameters, clicks all the opened parameters to find the kernel version, and clicks it three times in a row to enter the engineering mode of the mobile phone. After entering the engineering mode, find the distance sensor test in the hardware test. According to the above tips, move your finger to check whether the distance sensor works, and then click Start Calibration. If the calibration passes below the calibration start, it means that the effect of the distance sensor has been adjusted to the best state and can be used normally.

Distance sensors are generally located on both sides of the receiver or in the receiver groove to facilitate its work. When the user answers or makes a call, he holds the mobile phone close to his head. When the distance sensor can measure a certain distance, he informs the screen background light to turn off, and then lights it after taking it away, which is more convenient for users to operate and saves electricity.
