Among the most common MIUI errors we find the famous black screen when listening to making calls, listening to WhatsApp audios or any other action that makes use of the proximity sensor of our Xiaomi.

This failure, in most cases, is due to a malfunction of the proximity sensor . If this is wrongly calibrated, its operation will not be correct, mistakenly detecting that we have our Xiaomi in our pocket or placed in our ear and therefore, turning off the screen automatically.

Resolving this failure, which brings so many heads, is as simple as recalibrating the proximity sensor , an adjustment that, although not complicated, does require following certain steps to be done correctly.

Solution to the black screen on your Xiaomi, Redmi or POCO

If the proximity sensor of your Xiaomi is miscalibrated, it is very likely that the screen will suddenly turn off when listening to audio or making calls even if we do not have the device in our ear.

To correctly calibrate the proximity sensor of any Xiaomi, Redmi or POCO device, we will only have to perform the following steps:

1. Go to Settings> About phone> All specifications
2. Once inside, we will click several times on the " Kernel version " section until the CIT Menu opens from which we will be able to calibrate the different sensors and hardware components of the device.

Once we have accessed the CIT Menu, the next step will be to check the status of the proximity sensor and, at the same time, calibrate it . To do this, simply perform the following steps:

1. Access the " Proximity sensor " option and then click on the " Error " or " Fail " button.
2. Then we will restart our smartphone

In this way we will indicate to the system that the proximity sensor is incorrectly calibrated , adjusting it automatically once we have restarted the device.
