How to turn off the accelerometer on Xiaomi: the complete guide

Modern smartphones, including popular Xiaomi models, are equipped with a variety of sensors that make the device comfortable to use. One of these components is an accelerometer responsible for determining the position of the phone in space and turning the screen. However, users often face situations when this sensor begins to work incorrectly, causing spontaneous interface turns or game glitches.

The need to disable or reconfigure the accelerometer can arise for various reasons, from a banal irritation to a serious software error that interferes with the normal operation of the gadget. Owners of Redmi and Poco often look for ways to solve this problem, as standard menus sometimes hide the necessary options.

It's important to understand that you can't completely turn off the sensor at the hardware level in normal operation without losing some functionality. However, there are software methods for blocking its signals, calibrating or disabling associated functions. We'll go into each of the ways in detail, from simple adjustments to more complex engineering manipulations.

Why you might need to shut down the sensor

The accelerometer is a microelectromechanical system that responds to acceleration and gravity. In Xiaomi smartphones, it is responsible not only for turning the screen automatically, but also for pedometer operation, control in games with the tilt of the body and some control gestures. Sometimes this sensor begins to "glut", especially after a device falls or moisture hits.

The main reason users want to turn off the accelerometer is because it doesn't work properly. The screen can flip randomly, interfering with reading or typing. In some cases, a faulty sensor can cause an elevated battery drain, as the system constantly polls the sensor to determine the position of the device.

There are also specific use cases where accelerometer intervention is not desirable, such as when using the phone as a stationary terminal or when connecting to an external display in horizontal mode, automatic rotation can knock down the display settings, and this is also true for people who use special mounts, where the physical rotation of the device should not affect the software image.

It's worth noting that the Android operating system that runs the MIUI or HyperOS shell doesn't have a direct "Switch off the accelerometer" button on the standard menu, so you have to resort to workarounds, such as blocking the orientation of the screen or using third-party software to intercept sensor signals.

⚠️ Warning: Complete software shutdown of system sensors may cause unstable operation of some applications that are tied to geolocation or motion control.

Blocking the autoturn of the screen as an alternative

The easiest and safest way to limit the impact of an accelerometer on user experience is to turn off the autorotation function. This does not deactivate the sensor itself, but prevents the system from responding to its signals by changing the orientation of the interface. For most users, this solution is optimal and does not require deep intervention in settings.

To activate this feature, you need to lower the swipe notification curtain from top to bottom. In the quick access panel, you need to find an icon with the image of the lock or arrows in the circle. In different versions of Xiaomi firmware, it can be called “Orientation” or “Orientation Lock.” If you click on it, the screen will lock in the current position.

You can find more detailed settings in the settings menu, and then you can go to Settings → Screen → Screen Autoturn, and you can not only turn the function on or off, but you can also customize the behavior for individual applications. Some versions of MIUI allow you to set a forced landscape or portrait mode for the entire system.

• 🔒 Blocking through the notification curtain is the fastest method.
• ⚙️ Setting up through the screen menu gives you more control.
• 📱 Compulsory regime in individual annexes.

Using orientation locking allows you to ignore the accelerometer readings when they are not needed, which is especially useful when watching video in the supine position, when the phone is on its side, but the picture should not be turned over, so you effectively "disable" the visible result of the sensor.

Calibration of the accelerometer through the engineering menu

If the problem is not the desire to turn off the function, but the sensor is not working correctly, then the best solution is to calibrate it. In Xiaomi smartphones, there is a hidden engineering menu that allows you to test and adjust all hardware components, including the accelerometer. This method often helps eliminate the “shaking” of the cursor or the wrong turn of the screen.

To enter the engineering menu, you need to open the Phone app and type a special code. Most often, for devices based on MediaTek and Qualcomm processors, the command ##6484## or ##4636## is used. After entering the code, the CIT menu will open, where you will see a list of all available tests.

You'll find a point on the test list that's associated with the accelerometer, which can be called the Accelerometer, the G-sensor, or just the Position Sensor. And as you go into this section, you'll see the current readings of the X, Y, Z. You'll usually need to place your phone on a perfectly flat horizontal surface and press the Calibrate button to start calibrating.

The calibration process takes a few seconds. The system reads the reference values of the zero position and writes them to memory. Once the test is completed successfully, you need to restart the device. If the calibration did not help, it may be a hardware problem, and the sensor needs to be replaced at the service center.

Remember that the engineering menu is a powerful tool, and changing unknown parameters can lead to unstable system operation, it is recommended to touch only those settings that relate directly to the calibration of sensors, and not to change network or system configurations unnecessarily.

Use of third-party applications for management

Since standard Android tools can not completely disable data transmission from the accelerometer, many users turn to third-party applications. In the Google Play store, there are many utilities that allow you to intercept sensor signals and block their transmission to the system or specific applications.

One popular solution is advanced-screen rotation-blocking applications, such as Rotation Control or Ultimate Rotation Control, which have deeper access rights and can force the screen to be directed by ignoring system settings and accelerometer readings.

There are also specialized sensor management applications that require superuser (Root) rights, which can be used to software-smoke the sensor, but gaining Root rights on modern Xiaomi smartphones involves unlocking the bootloader, which can lead to a loss of warranty and the inability to use banking applications.

Without Root rights, third-party applications are limited; they can only simulate shutdown by blocking interface response. For ordinary users, installing a robust orientation control application is the safest and most effective way to solve the problem without risking damage to the system.

⚠️ Note: Installing applications from unknown sources or using modified versions of software can create security vulnerabilities in your device.

Resetting and debugging through ADB

For advanced users familiar with the Android operating system, there is a method of debugging through a computer using the ADB (Android Debug Bridge) tool, which allows you to send commands directly to the system without passing the graphical interface, and can be used to reset sensor settings or change system parameters.

Before you start, you need to activate the developer mode on your smartphone. To do this, go to Settings → About the phone and quickly click on the build number seven times. Then the option “For Developers” will appear in the “Additional” or “Extended settings” menu, where you need to turn on “Debugging by USB”.

By connecting the phone to a computer and installing ADB drivers, you can execute commands. For example, cleaning the cache of the relevant system services sometimes helps to reset sensor settings. Commands are entered in the terminal or command line. The example of a command to restart the sensor service can look difficult, so beginners should limit themselves to standard methods.

adb shell settings put system accelerometer_rotation 0

This command forcibly disables the autorotation of the screen at the system setting level. It is similar to the menu action, but it is done software. More complex manipulation of sensor drivers through ADB requires Root rights and a deep knowledge of the Linux architecture on which Android is based.

If software methods, including resetting the settings via ADB, do not help eliminate the chaotic behavior of the screen, the likelihood of physical failure is high, in such cases, software shutdown becomes the only way to keep the phone usable, albeit with limited functionality.

Comparison of accelerometer control methods

To make it easier for you to choose the right way to solve the problem, we have prepared a method comparison table that will help you assess the risks, complexity and effectiveness of each approach for different Xiaomi, Redmi and Poco models.

As you can see from the table, for most cases, standard orientation locking is enough, the engineering menu should only be used if the sensor is clearly lying and requires adjustment, and the more complex methods should be left for the last resort when other methods have failed.

💡

Before any manipulations in the engineering menu, take a screenshot of the initial calibration values so that you can return to them in case of failure.

Keep in mind that the software is constantly updated. With newer versions of HyperOS, the paths to settings may change, and some hidden codes may be blocked by the manufacturer for security reasons. Always check the relevance of the information for your particular firmware version.
