Many Xiaomi smartphone owners face a situation where the screen of the device suddenly goes out during an important conversation or, conversely, does not turn off when the phone is brought to the ear. On the Redmi Note 10 Pro model, as well as on other devices of the brand, a special module is responsible for this, which often causes complaints from users due to improper operation.
This feature may need to be turned off in a variety of situations, such as if you're using a headset but the screen is still responding to hand movements, or if the protective glass is closing the sensor area. The proximity sensor is the infrared emitter and receiver that are at the top of the display. Understanding how it works will help avoid accidental locking of the interface at the wrong time.
In this article, we will take a look at all the available sensor deactivation methods, from standard MIUI settings to more complex engineering menus, and we will also look at why this sensor may behave incorrectly, and whether it should be completely abandoned in the daily use of your Redmi Note 10 Pro.
The reasons for the incorrect operation of the sensor on the Redmi Note 10 Pro
Before we start taking drastic measures to completely shut down the functionality, we need to understand all the problems. Often users blame the hardware module itself for the failure, whereas it can be a software error or a physical obstacle. On the Redmi Note 10 Pro, the sensor is located in a thin strip above the screen, and even minimal contamination can disrupt its operation.
One of the most common causes is poor-quality protective glass or film. If the accessory has a black frame or just too thick adhesive at the top, the infrared beam can't pass through it, so the phone "thinks" it's in your pocket or ear, and locks the display, and can cause problems with cases with high sides that block the view of the sensor.
⚠️ Warning: Before turning off the sensor, make sure the problem isn't caused by physical contamination.Wash the top of the screen with a soft cloth and remove the protective film to check.
In addition, MIUI malfunctions can cause the sensor to be miscalibrated, the system misinterprets the distance to the object, and sometimes it is enough to simply restart the device or update the firmware so that the software failure is fixed without having to go into deep settings.
Disconnection through standard call settings
The easiest and safest way to remove unnecessary functionality is to use the built-in interface options of Xiaomi. This method does not require root rights or install third-party software and is completely reversible. However, it is worth considering that the location of points may vary slightly in different versions of the MIUI shell.
To start, open the standard Phone app that you use to make calls, and that's where the switch is hidden, and find the gear icon or the three dots in the corner of the screen to enter the settings menu, and we're interested in the incoming call section.
Inside the settings menu, find Mode in your pocket or Proximity Sensor, which can vary depending on the location of the system. By turning off this switch, you will prevent the system from turning off the screen when objects approach, a solution that is ideal for those who use headsets or speakerphones.
After the settings change, a test call is recommended, hold your palm to the top of the screen and check if the display is reacting. If the screen continues to go out, it may be that the system has activated sensitive mode or a third-party call app conflicts.
Use of the Engineering Menu for Calibration and Disconnection
If standard methods fail, you can use the Android engineering menu, which is a hidden part of the system that's designed to test hardware by engineers, and you can not only turn off the sensor, but also recalibrate it, which often solves the problem of false positives.
To enter the engineering menu, open the Phone app and type a special code. Xiaomi devices most often use the combination ##6484## or ##4636#. Once you enter the last digit, the menu will open automatically.
In the window that opens, you'll see the current distance. Close the top of the screen with your hand, the value should change. If there's no response, the sensor may be physically malfunctioning. You may need to turn off or reset the settings by either "Calibration" or "Off." Be careful that changing unknown parameters can cause the system to malfunction.
☑️ Checking in the engineering menu
It's important to understand that the engineering menu is a diagnostic tool. You may not be able to completely disable the sensor from here on all firmware versions. If you haven't found an explicit Disable switch, use this section only to check that the hardware is working properly.
Application of third-party applications for sensor management
When MIUI system constraints don’t allow you to flexibly customize your smartphone behavior, apps from the Google Play store come to the rescue. There are many utilities that can intercept the control of the proximity sensor and turn it off forcibly during calls or in certain scenarios.
One popular solution is the Proximity Sensor Reset & Fix app, or analogues like Sensor Box, which not only allows you to test the sensor, but also allows you to program a ban on its use by specific applications, for example, only for Phone or Telegram.
Installing such software requires special permissions. When you first run the application can request access over other windows or permission to use the equipment. Once set up, you can create a profile in which the proximity sensor will be ignored by the system.
| Annex | Functional | Advertising | Difficulty |
|---|---|---|---|
| Proximity Sensor Reset | Calibration, test, reset | There is. | Low. |
| Sensor Box | All sensors test. | No. | Low. |
| Call Assistant | Screen control when calling | There is. | Medium |
| ADB Commands | Complete shutdown via PC | No. | Tall. |
Using third-party software is a trade-off: on the one hand, you get the control you want, on the other hand, an additional process in the background can consume battery power.
Radical Method: Disconnecting via ADB commands
For advanced users who want to securely disable the sensor at the system level without root rights, there is a method using Android Debug Bridge (ADB), which requires connecting the smartphone to the computer and executing commands in the command line, which allows you to remove or freeze the system component responsible for the sensor.
First, activate the developer mode on the Redmi Note 10 Pro, click on the build number seven times in the About Phone section, then turn on the USB Debugging menu from the Developer menu, connect the phone to your PC, and install the ADB drivers.
Once connected, run a command to find the package responsible for the sensor, usually associated with Xiaomi services, and the command to disable the component may look like this:
adb shell pm disable-user --user 0 com.android.proxysensorThe specific name of the package may vary depending on the version of MIUI. Before you enter a command, it is strongly recommended to find the current package for your model on the developer forums.
⚠️ Attention: Use ADB Incorrectly disabling the system package can lead to a cyclic restart (bootloop) or loss of other functions!
This method is considered the most effective, because it affects directly the Android software layer, but after resetting to factory or updating the firmware, all changes will be pumped out and the procedure will have to be repeated.
Influence of accessories and physical factors
The problem is often much easier than it seems. Redmi Note 10 Pro owners should know that the design of this smartphone involves placing the sensor in a narrow frame above the display. Any thickening in this area is critical. Cheap protective glass with black edging is the main enemy of the correct operation of the sensor.
If you're using a case, look at the shape of the case. Some models have curved edges that hang over the screen. Even if they don't visually close the sensor, they can create a shadow or reflect the infrared back, causing a false alarm. Try removing the case and checking the work.
Also worth mentioning is the temperature factor: when the case is heated, electronic components can work with errors, and if the phone overheats during play or charging, the sensor can behave unpredictably until the device cools down.
Dirt, finger fat or dust in the speaker's grid can also block the emitter. Regular cleaning of the top of the smartphone with compressed air or a soft brush will help maintain hygiene and functionality.
