There are not a few users who on Xiaomi mobile phones have run into countless problems in Xiaomi when trying to make calls or when listening to WhatsApp and Telegram audios . In the forums we find many complaints about it without too many explanations and solutions, so we want to help you to make calls without the MIUI black screen problem.
Previously we had seen some cases and failures that made the screen of Xiaomi phones turn black, but nevertheless this has nothing to do with it. In this case, the fault appears when trying to make calls with the mobile and is related to the proximity sensor, either because it does not work well or because it has been miscalibrated.
Calibrate the Xiaomi proximity sensor
The only thing we have to do so that this failure does not repeat itself is to make the person in charge of activating or deactivating the screen in calls work as it should, something that we will do from the Xiaomi engineer menu with which we will be able to directly modify the hardware of the device directly so that the problem does not recur. In other tutorials we have seen that the calibration is done from the secret menu, but it does not have the same results as in this way.
- To begin what we will do is enter the Settings of our Xiaomi.
- Later we touched on On the phone.
- We go down to where we see All the specifications.
- To finally touch repeatedly where it says “Kernel version”.
Which will take us to the next Xiaomi CIT menu with countless tools that we cannot otherwise use. This is typical of the Chinese firm and therefore we can not use it in other brands, only in Xiaomi, Redmi and Poco.
We will have to locate the option called “Proximity sensor” which in some versions of MIUI forces us to touch on the top three points to be able to touch on “Additional tools”. Once we find it, we will only have to touch on the option to take us to the new screen where we will check if the proximity sensor works correctly.
Here we will have to try to cover the proximity sensor with our hand as if it were urine when making a call, in this way we try to check if the sensor is failing and is what causes the screen of our Xiaomi to go crazy in the calls . In case it never gets to 1.0 and 0.0, we will have the problem located. To fix it we have to tap on “Fail”. Exit the application and restart the mobile normally.
By doing this the mobile will try to fix it without any risk of the data when it is turned on. Then we would only have to make a test call and check that now everything works as it should and the black screen in Xiaomi does not fail as it used to.
