There is an issue around Xiaomi that has given a lot to talk about in recent years and that is that the proximity sensor of some models did not work correctly. These problems have disappeared with several of the most recent releases, so don’t be alarmed if your new smartphone misses it.
When all this commotion began to take place, the technological giant did not hesitate to investigate to locate the origin of the problem, and everything indicated that it had to do with the use of a virtual sensor as opposed to the optical one of most devices on the market. This bug has disappeared with the rise of the Xiaomi 12 family and everything has a logical explanation.
A unique sensor of its kind
The purpose of the proximity sensor incorporated in current smartphones is quite simple and involves turning off the screen when we bring the mobile closer to our ear . In this way, the user will not accidentally press buttons, which could cause him to hang up the call while talking on the phone.
Precisely for this reason it has been an ordeal for many owners with Xiaomi or Redmi phones. That is why the Asian brand did not hesitate to solve the error as soon as possible and the new generation of devices has completely got rid of these errors.
This is because the company has entered into a contract with Elliptic Labs to develop a virtual proximity sensor . This works with an artificial intelligence and achieves a good result. In addition, it seems that the relationship between the two is seen in the long term, so it is more than likely that future releases will also leave this problem behind.
This Elliptic Labs sensor is emerging as a high-level alternative without the need to go to hardware and take up space between components. This means that your Xiaomi is really missing a piece, but you will not miss it much less. Moreover, other manufacturers would be considering following this same path, where Xiaomi is a pioneer.
How to calibrate the Xiaomi sensor if it fails
There are models from months ago that do not get rid of this failure of the Xiaomi proximity sensor, but with a little trick you can use the smartphone normally again . In addition, it should be noted that this problem does not affect excessively during daily use, but when talking through a phone call it was somewhat annoying at times. Precisely for this reason we are going to teach you how to quickly calibrate it without downloading anything.
The secret codes that all mobile phones on the market incorporate have all kinds of functions and among them is that of calibrating the sensor. To do this, you just have to open the Phone app and type the following sequence: *#*#6484#*#* .
This will cause a hidden menu to appear where you can check verifications of many terminal components. Go to section number 22 called “Proximity sensor test” and perform the steps indicated by the system, placing your finger just above the sensor and appreciating the number that appears from zero to five.
