How to Calibrate the Autoturn of the Screen on Xiaomi: Expert Guide

The situation when the autorotation of the screen on your smartphone ceases to respond to a change in the position of the case, familiar to many owners Xiaomi, Redmi and Poco. Instead of a smooth turn of the image when turning the device into landscape mode, the picture remains frozen, which creates a tangible discomfort when watching videos or reading documents. Often users believe that the problem lies in the hardware damage to the accelerometer or gyroscope, but in most cases the failure is software in nature and is solved by simple calibration.

Modern displays are controlled by complex sensor algorithms that can fail after a crash, firmware update, or third-party launcher installation. If you notice that the turn is not working correctly, “twitches” or completely ignores your actions, do not rush to carry the gadget to the service center. There are a number of effective methods to calibrate sensors right at home, using the hidden capabilities of the MIUI or HyperOS system.

In this article, we will take a closer look at all the ways to restore the G sensor to normal, and we will look at both standard methods through the settings menu and more advanced options through the engineering menu available on most Xiaomi devices, and understanding how these mechanisms work will help you not only fix the current bug, but also prevent it from occurring in the future by ensuring that the interface works smoothly.

Diagnosis and causes of turning failure

Before you start actively calibrating the screen, you need to pinpoint the source of the problem. It's not always the fault of the sensor itself. Often it's software conflicts, system services freezing, or the banal activation of orientation lock. The first thing you need to do is make sure that the notification curtain doesn't activate the lock icon that forcibly captures the position of the image.

One common reason is the accumulation of errors in the accelerometer after a long time of operation of the device without rebooting. The system may not correctly read the data about the position in space if the background processes are overloaded.

If a standard reboot didn't work, you should pay attention to the physical condition of the gadget. Falls or heavy impacts could displace sensitive elements inside the housing. However, even in such cases, software recalibration often allows you to adjust the sensor readings and return functionality. It is important to understand the difference between a complete failure (the screen does not respond to anything) and incorrect operation (the screen turns, but with a delay or in the wrong direction).

⚠️ Note: If your smartphone has recently been subjected to severe mechanical stress, the software calibration can only give a temporary effect.

Basic configuration through the system menu

The easiest and safest way to try to restore performance is to use the regular MIUI tools. In the latest versions of the shell, developers have added convenient switches that are often ignored by users. The first step is to check the activation of the autorotation function in the control center. To do this, swipe from top to top to open the curtain, and find an icon with an arrow or a lock.

If the switch is active but the screen is not rotating, try to force resetting. Go to Settings → Screen and find the item responsible for font size or image scale. Changing these parameters causes the system to redraw the interface, which can shake up the suspended orientation control process. After rescaling, return the settings to the original values.

Also worth checking is the settings of special features that can block the turn. Some features for people with disabilities take priority over standard system behavior. Make sure that in the Settings → Advanced Settings → Special features are not included features that capture the orientation of the screen.

An important diagnostic element is to check that it's safe, and if it's a rotating mode that's working correctly, it's a third-party application that can be used to determine the culprit by eliminating the recently installed programs.

Engineering menu and CIT-testing

The most effective tool for deep diagnosis and customization is the engineering menu, accessible through special code. This hidden section allows you to interact with hardware sensors directly, bypassing the standard interface. To enter the menu, you need to open the Phone app and enter the combination ##6484#. On some models, the code may differ, for example ##4636#, but the first option is the standard for Xiaomi.

Once you enter the code, you'll see a list of CITs, or a Customer Integration Test, and you'll find an Accelerometer or a G-sensor in the list, and you'll click on it, and you'll be asked to put the device on a flat horizontal surface, and that's a critical point: the surface must be absolutely flat so that the system can lock in the reference zero position.

The calibration process is usually as follows:

• 📱 Put the smartphone screen up on a flat table.
• 🔄 Click the “Calibrate” or “Start” button in the test menu.
• ⏳ Wait for the process to be completed without touching the device.
• ✅ Make sure the status is changed to Pass or Success».

If the test is successful, the system will automatically record new correction factors for the accelerometer. It is recommended to restart the device to take effect at the kernel level of the system. In some cases, it may be necessary to repeat the procedure several times if the sensor has a significant range of readings.

Calibration through the hidden Android menu

In addition to the Xiaomi utility, the Android operating system has a universal test menu available through code #0# or through the settings for developers. However, on the MIUI shell, access to it is often limited. The alternative is to use ADB (Android Debug Bridge) from a computer, which requires a USB connection and drivers.

For users who don't want to mess with the command line, there's a method of resetting sensor settings through the Recovery menu. Although there's no direct calibration, resetting the data partition (requiring deletion of all data) is guaranteed to return all system configs to factory values. This is a radical method, but it's effective at software failures.

A softer option is to use calibration apps from the Google Play store, programs like GPS Status & Toolbox or specialized Android utilities can send system requests to reset sensors, and they work in a similar way to the engineering menu: they ask to put the phone on a flat surface and perform a reset command.

⚠️ Note: Using third-party calibration applications requires granting them extended permissions.Be careful and download only programs from trusted developers so that the security of your data is not compromised.

It is worth noting that on new versions of Android 12/13/14 Access to low-level sensor features for third-party applications is limited by security policies. CIT-Xiaomi Menu is the most reliable tool.

Comparison of sensor recovery methods

The choice of calibration method depends on the degree of the problem and your readiness for technical manipulation. Below is a table comparing the main ways to solve the problem of turning the screen on Redmi and Poco devices.

As the table shows, the best balance between safety and efficiency is the use of the CIT-It does not require root rights, a computer, or deletion of personal files, and resetting to factory settings should only be considered as a last resort when all other methods have been exhausted.

Prevention and additional advice

To prevent the autorotation problem from returning, a number of simple rules of operation are recommended: Regularly update the system and applications, as developers often release patches that correct the operation of hardware drivers. Also avoid overheating the device, as high temperatures can affect the accuracy of readings of electronic components.

Use high-quality protective glass and film. Cheap accessories can have uneven thickness or pressure on the edges of the screen, which indirectly affects the performance of the touchscreen and sometimes confuses the positioning algorithms. If you use magnetic cases or holders in the car, make sure that the magnets are not located in the area of the Hall sensors.

💡

If the autorotation is unstable, try turning off Adaptive Brightness. Sometimes these two sensors (lights and accelerometer) conflict when software errors occur.

Periodically check the sensors through the engineering menu, especially after falls. Early detection of drift readings of the accelerometer will allow you to adjust it before using the phone becomes impossible. Remember, accurate calibration is possible only on a flat horizontal surface without vibrations.
