Flagship owners often seek to expand the functionality of their gadgets using additional accessories. One such useful addition is a smart case that is able to automatically control the screen and protect the smartphone from accidental presses in the pocket. For the Xiaomi Mi 10 Pro model, the correct configuration of this accessory is critical, since without it the device may not respond to closing the lid or, conversely, lock too aggressively.
Many users mistakenly believe that it is enough to simply put on the accessory and it will work on its own. However, the MIUI operating system on which the smartphone interface is based requires manual intervention to correctly operate the proximity sensors and magnetic sensors of the case. Ignoring this stage leads to the fact that the screen continues to burn in the pocket, consuming battery power, or the phone does not respond to the opening of the cover when an incoming call.
In this guide, we will take a detailed look at the process of activating all the necessary functions associated with the protective case, you will learn where the switches are hidden, how to calibrate the sensors and what to do if standard methods do not work. Competent setting will not only save energy, but also prolong the service life of the display, preventing pixels from burning out during prolonged downtime.
The principle of operation of smart cases with Xiaomi Mi 10 Pro
The mechanism of interaction between the smartphone and the smart case is based on the use of a magnetic field and a proximity sensor. In the side of the quality accessory, a small magnet is built, which when the cover is closed affects the sensors located in the upper part of the Xiaomi Mi 10 Pro body. The system reads the change in the magnetic field and interprets this as a command to lock the screen or go to sleep.
It's important to understand that not all cases are the same. There are Flip Window models that allow you to see time and notifications without opening the lid, and regular flips. The first often require installing a special plugin or activating Pocket Mode. Without this, the window can display incorrect information or not respond to touch.
⚠️ Note: Using cheap analogues without a magnetic tag can lead to the fact that the automatic lock function will not work, even if all settings in the system are activated.
Modern versions of the MIUI have advanced false positive protection algorithms. If the proximity sensor is contaminated or covered with a low-quality protective glass, the phone can ignore the signals from the case. So before setting up, it is recommended to wipe the top of the screen and make sure that the accessory fits tightly to the case.
Search and activate settings in the MIUI menu
The main control center for smart case functions is in the operating system settings, and the path to these may vary slightly depending on the firmware version, but the logic remains the same. You need to open the main menu and find the Settings section, which is usually indicated by the gear.
Then you go to the Lock screen section, and this is where you focus on the device's behavior when you close the lid, and in some versions of the interface, this item may be called "Blocking" or placed in a separate menu called "Special Features" for specific accessibility features.
Inside the menu, you need to find a switch that controls the pocket dial or smart case mode. On global firmware versions, it is often labeled as pocket dial mode. Activating this switch allows the system to understand when the device is in a confined space and disable the touch layer to prevent accidental calls.
- 📱 Open Settings through the main menu or notification curtain.
- 🔒 Go to the Lock Screen (or "Passwords and Security").
- 🛡️ Find the Pocket Set Mode and activate it.
- ✅ Check for additional settings for window accessories.
Once the main function is enabled, the system may request confirmation or suggest calibrating the sensors. Follow the on-screen instructions. If the switch is missing, your version of MIUI may require an additional component to be installed via the Themes or Services app.
💡
If you can’t find the item “Package mode”, use the search by settings: enter the word “pocket” in the search bar at the top of the settings screen.
Configure accessories with window and plugins
Owners of Xiaomi Mi 10 Pro using cases with a transparent window often face the need to install a special plugin. Standard system tools may not be enough to display widgets of time, date and notifications through the notch in the lid.
To find the right plugin, open the Themes app. In the lower right corner or in the profile menu, look for the Plugins or Accessories section. In the list of available add-ons, look for a component that matches your model or type of case (for example, "Smart Case Plugin" or "Flip Cover").
Once you install the plugin, you'll see a new option in the lock screen settings that allows you to select the style of displaying information in the window, so you can adjust the time format, background color and set of notifications that you display, and this turns a regular case into a full-fledged information center.
⚠️ Note: Smart case plugins can consume extra battery power as they keep part of the display active even in sleep mode.
Some third-party case manufacturers require their own applications from Google Play, in which case the information about the required software is usually contained in the instructions embedded in the box, or on the box. QR-Scanning the code with your smartphone camera will automatically redirect you to the download page.
What to do if the plugin is not installed?
Calibration of the proximity sensor for accurate operation
The correct operation of a smart case depends on the accuracy of the proximity sensor. If this sensor is knocked down or contaminated, the phone will assume that the lid is closed even when it is open, or vice versa. Xiaomi Mi 10 Pro has a built-in engineering menu to check and calibrate this component.
To enter the test menu, open the Phone app and type in the special code ##6484##. This action will open the CIT (Customer Interface Test) engineering menu.
Inside the test menu, you'll see the current sensor readings. Cover the top of the screen with your hand or case - the value should change (usually from 5.0 to 0.0 or vice versa, depending on the software version). If there is no reaction, press the Calibrate button and follow the instructions: close the sensor, then open it on the command of the system.
| Parameter | Normal condition | At closing | Failure action |
|---|---|---|---|
| Sensor value | 5.0 (or 1) | 0.0 (or 0) | Sizing |
| Screen reaction | horite | Gasnet | Checking the case |
| Indicator | Green. | Green. | Film replacement |
Once you've calibrated successfully, be sure to restart the device, which will allow the system to apply new sensitivity values, and if the problem persists, it could be physical damage to the sensor or too thick a protective glass that overshadows the sensor's view.
☑️ Testing of the proximity sensor
Solving problems with false positives
Even after the right setup, users may find themselves in a situation where the Xiaomi Mi 10 Pro behaves unpredictably, the screen may go out during a conversation or, conversely, not lock in their pocket, most often due to software conflicts or physical interference.
One of the common reasons is that there's a protective film or glass that covers the sensor area. Even a microscopic layer of dirt or a poor-quality glass can distort the readings. Cleaning the top of the screen with an alcohol napkin often solves the problem instantly.
You should also look at third-party screen control applications, if you have programs like Black Screen, Screen Off or similar, they may conflict with the system case management, and try temporarily disabling or removing such applications for verification.
- 🧹 Wash the top of the screen from fat and dust.
- 🚫 Remove third-party screen control apps.
- 🔄 Reset sensor settings through the engineering menu again.
- 📱 Check if the sensor covers the area mechanically.
In rare cases, the problem may be related to a specific firmware update MIUI. If after the update the smart case stopped working, it makes sense to wait for the patch or perform a full reset (pre-backup data).
💡
90% of smart case problems are solved by cleaning the proximity sensor and recalibrating through the engineering menu.
The effect of accessories on the autonomy of the device
The use of a smart case, especially models with windows and active widgets, has an impact on the life of the Xiaomi Mi 10 Pro from a single charge. Constantly polling sensors and highlighting part of the screen in sleep mode increase the background power consumption.
To minimize energy loss, it is recommended to turn off the display of complex widgets in the window of the case, unless urgently needed. Leave only the clock or date. You can also set the screen timeout so that it goes out faster when the cover is closed.
MIUI has a built-in battery optimizer. Go to Settings → Battery → Energy Saving and make sure that the system processes responsible for locking do not have a background activity limitation that could disrupt the operation of the case. The balance between functionality and autonomy is a key point of setting.
⚠️ Attention: Constant operation of sensors in the mode of "smart case" can increase battery discharge in standby mode 5-10% day-to-day.
If you notice that the phone is very hot in the case, even in a simple case, this may indicate a software failure in which the processor does not go to sleep, in this situation, it is better to temporarily turn off the functions of the smart case and contact the service center for diagnosis.
