Often, users are faced with an unpleasant situation when the screen does not turn off during a call. Because of this, accidental clicks occur, which entails the launch of unnecessary applications and functions. The proximity sensor just solves this problem. Therefore, in today’s article, we will discuss how to enable, disable and calibrate the proximity sensor on Xiaomi and Redmi phones.
What is the proximity sensor for?
The proximity sensor is a special sensor responsible for automatically turning off the display during a telephone conversation. The screen becomes inactive, so you cannot make an accidental press by hooking the display with your ear or cheek. Proximity sensor is located on the top edge of the smartphone, usually near the front camera. On modern smartphones, the sensor is not visible due to the thin bezels.
The proximity sensor is responsible for muting voice messages when you bring the phone to your ear. That is, the sound begins to play through the auditory, and not the polyphonic speaker, due to which only you can hear the sound message. The sensor is also needed for the “Pocket” function to work. The display is again locked to avoid accidental clicks that occur when the phone is in your pocket.
As you already understood, the proximity sensor is a very useful tool to make it easier to use your mobile device. But almost all Xiaomi smartphones have a significant drawback – the incorrect operation of the proximity sensor. It may not work when you bring the smartphone to your ear, or it may work erratically, which is why the screen will go out and turn on again all the time. Therefore, many users want to completely disable the proximity sensor. But before taking such drastic measures, we recommend calibrating the sensor. How to do it – read in the next paragraph.
What to do if the sensor does not work correctly on Xiaomi
First, let’s consider what measures can be taken if the sensor is not working properly. In most cases, the steps below will fix the problem.
Removing or replacing the protective glass
Poor-quality protective glasses block the flow of light, as a result of which the light sensor stops working. Also, the problem may occur if you incorrectly glued the glass. Therefore, we recommend purchasing good quality glass (preferably original) and carefully stick it on the smartphone screen. Be sure to ensure that all sensor and front camera cutouts are not covered. Beginners should contact the service center: the wizard will quickly stick a protective glass on the phone display.
Disabling the Pocket function
As mentioned above, the “In pocket” option prevents accidental presses, but because of it, the sensor does not work when the smartphone is brought to your ear. So it’s better to turn off the function right away. For this:
1.Open “Settings” and go to the “Screen lock” section.
2.Deactivate the slider opposite the line “Mode” In the pocket “.
Calibrating the sensor
This is one of the most effective procedures, after which the sensor starts working correctly. To calibrate, you need to go to the engineering menu. And here is an important point: not all models have the ability to calibrate the sensor. If your smartphone is running a MediaTek processor, you can perform this operation. If Qualcomm Snapdragon is installed, calibration is not available.
So, go to “Settings” – “About phone”. Open “All parameters” and 5 times quickly click on the line “Kernel version”. The hardware test menu appears. Click on the ellipsis in the upper right corner. There should be a tab “Proximity sensor calibration”. Click on it and follow the prompts on the screen.
Even in the engineering menu, you can check the performance of the proximity sensor. The feature is available for both MTK and Snapdragon devices. Scroll through the menu and find the “Proximity sensor” tab. Several times we put our hand to the top panel of the phone, where the sensor is located, and look at the “Sensor Value” value. If the number changes from zero to five, then the sensor is working correctly (when you bring your hand up, zero should be displayed; if the sensor is not covered by anything, it will be number five).
Disabling the sensor in MIUI 12
If the proximity sensor does more harm than good, you can turn it off completely. Again, this feature is not available for all smartphones. For example, on my Redmi Note 10 5G with MediaTek Dimensity 700 5G processor, there is no function to enable / disable the sensor.
1. In “Settings” open “Applications” – “System applications”.
2. Select the item “Calls”.
3.Scrolling down the page to the “Incoming Calls” tab.
4. We are looking for the item “Proximity sensor” and deactivate the slider.
1. Turn on developer mode.
2. Go to the section “Advanced settings” – “For developers”.
3.Open the “Items in quick settings” tab.
4. Turn on the slider next to the “Sensors disabled” line.
Please note that other important sensors may not work after enabling this option.
Using third-party software
There are many applications on Google Play that are supposedly designed to calibrate the sensor. But in fact, there is practically no benefit from them. The functionality of the sensor depends primarily on the firmware, and it will not be possible to somehow influence this with the help of third-party programs. But you can download an application to check the performance of the sensor. But is it worth doing if the system engineering menu is perfect for such purposes? Decide for yourself.
We figured out how to calibrate and enable / disable the proximity sensor on Xiaomi. Everything is done very simply and quickly. Write in the comments if you are satisfied with the work of the proximity sensor in Miyuay.
