Modern Xiaomi smartphones, which are based on the shells MIUI or the new HyperOS, are equipped with many smart features designed to simplify interaction with the device. One of these features is automatic image rotation, which responds to changes in the position of the gadget in space. However, users often face a situation when the screen turns at the most inappropriate moment or, on the contrary, refuses to change orientation when watching video. Understanding the logic of the system will help avoid irritation from unexpected changes in the interface.
At the heart of this mechanism is a complex interaction between software algorithms and hardware sensors. When you pick up your phone, the accelerometer and gyroscope instantly read the device's tilt angle relative to the ground, and this data is transmitted to the operating system, which decides to change the orientation of the content. If Autopivot is enabled, the system automatically switches the interface from portrait mode to landscape mode. Problems can arise from both software conflicts and physical failure of the sensors or their miscalibration.
In this article, we will discuss in detail why the xiaomi screen turns on, how to control this parameter, and what to do if the function is not working correctly. We will look at the hidden settings, methods of calibrating the engineering menu and software features of different firmware versions. The approximation sensor failure is often confused with the accelerometer malfunction, although these are different modules responsible for different functions.
The principle of operation of orientation sensors in MIUI and HyperOS
The foundation for automatic rotation is a bunch of sensors built into the smartphone motherboard, and the main role here is played by an accelerometer that responds to the acceleration and static position of the device, which tells the system that the phone has been turned sideways. In the newer models of Redmi and Poco, a gyroscope is connected to work, which provides more accurate and smooth tracking of movements in three planes, which allows the interface to respond almost instantly.
But just counting data isn't enough. Xiaomi's Android operating system is constantly analyzing the flow of sensor information. If you hold your phone at a 45-degree angle, the system can ignore the turn request to avoid accidental switching. The algorithm only works when you change position by 90 degrees. The software filter prevents the screen from flashing chaoticly when the user just tilts his head a little or changes the grip of the device.
It's important to understand that different apps have different priorities, like a YouTube or VLC video player that compulsively requests landscape mode, ignoring some of the system's limitations, while in settings menus or banking apps, the turn can be blocked by developers for the sake of security or text readability. MIUI allows you to flexibly adjust these settings, but by default seeks to follow Google standards.
Technical details of the sensors
The main reasons for spontaneous inclusion of the function
A situation where the screen is rotated without the explicit desire of the user can be caused by several factors: most often the problem lies in a software failure or incorrect operation of a particular application. Sometimes the background process can send a false signal to the system about changing orientation, this often happens after a firmware update, when old cache files conflict with new system libraries.
Another common reason is physical exposure to sensors: If the phone is lying on an uneven surface or vibrating from a nearby engine, the accelerometer can detect a change in position. It is also worth considering magnetic fields: powerful magnets in car covers or holders can affect the operation of the magnetometer, which indirectly participates in determining the orientation in space.
There is a button in the Xiaomi notification curtain that can be accidentally activated or deactivated. The user may not notice that the autorotation mode has been turned on earlier and be surprised by the screen reaction. In addition, some design themes or third-party launchers can intercept the control of system functions, causing unpredictable interface behavior.
How to manage autoturn settings through the curtain and menu
The fastest way to control the orientation of the screen is to use the control panel. In the MIUI and HyperOS shells, access to these settings is unified. To change the settings, you don't need to go into deep system menus. You just swipe from top to bottom to top (depending on the control settings) to open the control center. There's a switch that visually shows the current state of the function.
If you want to completely stop the screen from changing position, you need to activate lock mode. In this state, even if you turn the phone horizontally, the image will remain vertical. This is useful when reading books in bed or using the navigator when the phone is fixed at an angle. To enable this feature, find an icon with the image of the lock or arrows.
In some versions of firmware, settings can be hidden or moved. If you don't find the right switch in the curtain, check the extended menu. Sometimes the system offers additional options, such as turning only in certain applications. To access the full settings, go to Settings → Screen → Screen Autoturn. Here you can see more detailed options, if they are available for your model.
☑️ Checking orientation settings
It is worth noting that in recent updates to HyperOS, the logic of the curtain has been changed. Now the icon can display the status of "Block" or "Stop" depending on the version of the interface. Be careful: if the lock icon is on, turn is blocked. If the icon is crossed out or the arrows are displayed, turn is allowed. Visual indication may differ on different models of the Redmi Note and Xiaomi Mi.
Calibration of sensors: elimination of software errors
If you notice that the screen is turning with a delay or, conversely, too sensitive to movement, you may need to calibrate the sensors. Xiaomi smartphones have built-in engineering menu that allows you to diagnose and adjust the sensors, this is especially true for devices that have been hit or prolonged use without rebooting.
To enter the engineering menu, open the Phone app and dial ##6484##. You will see a list of tests. Find a item associated with the Accelerometer or Gyroscope. Follow the instructions on the screen: you usually need to put the phone on a flat horizontal surface and press the calibration button. The system will determine the zero values and adjust the sensors.
💡
If the engineering menu doesn't open by code, try typing it in dial mode through the Phone app, not through contact search. CIT-The menu can be limited, then installing a special calibration application from Google Play will help.
Once the procedure is complete, be sure to restart the device, restart the system is necessary to apply new calibration values to hardware drivers, if after calibration the problem persists, it may not be a software failure, but a physical malfunction of the sensor, in which case the software methods will not help, and you will need to contact the service.
Table: Comparison of autorotation behavior in different applications
Not all apps respond to device turn the same way. Software developers decide whether to maintain landscape mode. Below is a table showing the typical behavior of popular programs on Xiaomi smartphones.
| Type of application | Turn reaction | Dependence on system settings | Examples |
|---|---|---|---|
| Video players | Automatic transition to the landscape | High (ignor lock in full screen mode) | YouTube, VLC, Gallery |
| Social media | Most often, only portrait mode. | Low (fixed orientation) | Instagram, TikTok, Telegram |
| browsers | Full support for both regimes | Medium (depending on the content of the page) | Chrome, Mi Browser, Yandex |
| Banking applications | Strictly Portrait Mode | Not present (protection from peeping) | Sberbank, Tinkoff |
And you can see from the table that waiting for the screen to turn on Instagram is meaningless, because the developers didn't originally put this feature in the first place, but at the same time, in the browser or when you view a photo from the gallery, the autorotation should work smoothly, and if the screen doesn't turn in support applications (for example, YouTube), then the problem is in the system or the sensors of the phone.
Solving sensor problems and resetting settings
When software calibration doesn't work, you can try more radical measures. Often it helps to reset all applications or completely remove the system cache. Go to Settings → Apps → All applications, find system processes associated with the display, and clean their data. Be careful: resetting system applications can return some personalization to the factory view.
⚠️ Warning: Before performing a full Hard Reset, be sure to back up all important data.This step will delete all photos, contacts and installed apps, returning the phone to the "out of the box" state».
If even a complete reset doesn't solve the problem, there's a high probability of hardware malfunction. The sensors in Xiaomi smartphones are quite reliable, but falling on a hard surface or getting moisture can make them fail. In this case, the screen can "think" that the phone is on its side, although you hold it upright. Diagnostics at the service center will take a little time and will allow you to accurately determine the cause.
💡
If calibration and resetting didn’t help and the screen continues to behave chaoticly, the problem is likely hardware in nature and requires a replacement of the plume or sensor module.
