Users of Xiaomi smartphones often face a situation where the interface of the device ceases to respond to a change in the position of the case. In the horizontal position, the screen continues to display the picture vertically, which makes watching videos or reading documents extremely uncomfortable. This function is responsible for a special system indicator, which is in the shell. MIUI The new HyperOS can behave differently depending on the firmware version.
Understanding how this control works allows you to instantly solve problems with the display of content. Screen auto-turn is not just a trifle, but a basic ergonomics function that should work flawlessly. In this article, we will discuss in detail the purpose of the icon, the reasons for its disappearance and methods of forced activation.
Today's touchscreen displays use built-in gyroscopes and accelerometers to determine the position of the device in space. When you turn the phone, the sensors send a signal to the Android operating system, which in turn rewires the interface. However, the manufacturer's software shell can block this process if the appropriate limiter is activated.
Purpose and function of the direction indicator
The main purpose of this interface element is to control the lock orientation of the display. Unlike many other brands where the icon directly indicates the turn on autorotate, in Xiaomi logic, it most often works as a lock switch. If the icon is on or active, the screen is fixed in the current position and will not respond to the turns of the device.
This is done to prevent random image flips, for example, when you lie on your side and read text, and in this position, the sensors can falsely fire to try to turn the picture, which annoys the user, activating the orientation lock allows you to lock the interface in a convenient state for you.
It's important to distinguish between software lock and physical inability to turn. Some applications, such as social networks or desktop launchers, were originally designed only for vertical mode. In such cases, the orientation icon will not help, since the program itself does not support horizontal display mode.
⚠️ Note: If the icon is activated but the screen still flips in some games or video players, this means that the application takes priority over system settings and forcibly changes orientation.
The MIUI system algorithm analyzes the active window. If a video player or a landscape-enabled game is running, the system can temporarily ignore the lock to provide a better user experience. However, in most standard applications, the icon acts as a rigid limiter.
Location of the icon in the interface MIUI and HyperOS
Finding the right switch can be a challenge for those who have recently switched from other smartphones. In the shell from Xiaomi, control of this parameter is placed in the control center. To get to it, you need to keep your fingers from the upper right corner of the screen down (or swipe from the bottom up if you have a classic style of curtain on).
In the menu that opens, you need to find an icon that looks like a lock inscribed in a circle of arrows, or just a lock that says "Orientation." Different versions of the firmware may have different designs, but the meaning remains the same, and clicking on this element changes its state from active to inactive and vice versa.
If you don't see this icon in the first group of icons, chances are it's hidden in the optional editing menu. Click on the edit button (usually three dots or a pencil in the corner of the curtain), find the "Orientation" or "Autoturn" element in the list of available toggles, and drag it to the active zone.
- 📱 Standard Location: Top row of Quick Settings panel, often next to Bluetooth or Do Not Disturb mode».
- 🔒 Visual designation: active lock means the lock on (the screen is not rotating), open or crossed out – the rotational resolution.
- ⚙️ Alternative path: display settings where you can find more detailed sensor control options.
- 🔄 Context menu: In some versions of HyperOS, when you turn the phone into the corner of the screen, a temporary unlock button may pop up.
Users who are used to standard Android are often confused, as the logic is often reversed: there the icon usually allows rotation, and here it forbids. In MIUI, an active lock icon means a ban on changing orientation, which is a key difference from stock Android.
☑️ Checking the availability of the function
Why the orientation icon may not work or not be available
When a switch is lost or no longer responsive to presses, it is quite common. The first and most common cause is a system process failure, SystemUI, which is responsible for rendering the interface, and a temporary error can cause individual controls to disappear.
The second reason could be conflicts with third-party launchers, where if you installed a design theme or an alternate desktop, they may overlap standard MIUI controls, in which case the icon is physically present on the system but not displayed on the screen due to the overlapping layers of the interface.
Also worth considering is software bugs of a particular firmware version: Xiaomi engineers periodically release updates that may contain errors in the code responsible for the operation of the accelerometer, in which cases the problem is massive and affects many users of the same model.
| Cause of failure | Probability. | Symptoms. | Method of decision |
|---|---|---|---|
| Lockdown activated. | Tall. | The screen is not responding to a turn | Turn off the curtain badge |
| SystemUI failure | Medium | Badge missing from the menu | Rebooting the device |
| Conflict of the topic | Medium | The interface is displayed incorrectly | Resetting the topic to standard |
| Sensor malfunction | Low. | The turn doesn't work anywhere. | Diagnostics in the engineering menu |
In Super-Economic mode, the system turns off many background processes and sensors to extend battery life, in which the orientation icon can be forcibly hidden and the autorotation blocked at the core level of the system.

Methods of forced activation and resetting settings
If a standard tap on the icon in the curtain fails, you need to move to deeper customization methods. The first step is to check the settings of the application itself in which you are trying to turn the screen. Go to Settings → Apps → All apps, find the problematic application (for example, YouTube or Gallery) and check if there is a separate item “Turn”.
The second method involves cleaning the system component cache. Sometimes temporary files get corrupted, which causes the interface to malfunction. Go to Settings → Applications → All applications, search the System Interface (or System UI) list, select Memory and click Clear. This will not delete your personal data, but reset the display settings.
A third, more radical method is to calibrate the sensors through an engineering menu, and to do this, in the Phone app, dial ##6484##. In the CIT menu that opens, select the item associated with the accelerometer and follow the instructions on the calibration screen. Put the phone on a flat surface and press the calibration button.
- 🔄 Reboot: A banal but effective way to restart all system services and reset sensor errors.
- 🎨 Change theme: Switch to the standard Classic theme in the Themes app to eliminate the impact of third-party code.
- 🛠 Resetting: in extreme cases, a full reset to factory settings will help, but first make a backup of the data.
⚠️ Warning: When calibrating the sensors, make sure the phone is on a completely flat and stationary surface. Any vibrations or tilts during the process will cause the autorotation to malfunction in the future.
It’s also worth checking for system updates. If the problem is caused by a firmware bug, a new security patch or MIUI update often contains a patch for the sensors to work. Go to Settings → About phone and click on the system version to check for updates.
💡
Use the Calculator app to quickly check it, open it and turn the phone around. If the calculator doesn't go into "engineered" horizontal mode, then the problem is exactly in the system or the sensors, not in the specific application.
The impact of third-party applications and design themes
MIUI shell is famous for its customization capabilities, but it is themes that often become a source of problems with system functions. Third-party themes change the markup files of the interface, and if the author of the topic did not take into account some element (for example, the orientation icon in the new version of Android), he may simply disappear or become unclickable.
Gesture control apps can also conflict with the standard curtain, and if you use third-party launchers like Nova Launcher or Microsoft Launcher, they can intercept swipe gesture control, preventing you from opening the quick settings panel where the switch is located.
Some reading apps or browsers have their own orientation settings that are more important than the system settings, such as a “Always Vertical” checkmark that will block any attempts by the system to turn the screen, even if the icon in the curtain is off.
To diagnose the problem, try running your phone in Safe Mode, which only downloads system applications, and if the icon appears and works correctly in Safe Mode, then one of the apps or themes you installed is to blame.
💡
Customization conflicts are the most common cause of system icons disappearing, and going back to stock theme helps solve 90 percent of these problems without having to be repaired.
Diagnostics of hardware malfunctions of the accelerometer
If software methods haven't worked, maybe the problem is hardware. The accelerometer is a physical sensor that can fail after a phone falls, hits or gets moisture. Unlike software failures, hardware failure requires hardware intervention.
Symptoms of sensor malfunction often manifest themselves not only in the absence of turning the screen; there may be “frambles” of the image when the screen spontaneously twitches when trying to turn, or navigation applications (maps) may misdetect the direction of movement.
For final testing, you can use specialized applications from Google Play, such as Sensor Test or GPS Status & Toolbox, to output raw data from the sensors, and if the X-axis or Y-axis values do not change when you turn the phone, the sensor does not physically work.
If a hardware malfunction is confirmed, the plume or sensor module at the service center will need to be replaced. Self-repair is possible only with experience in soldering chips, since the sensor is often soldered directly into the motherboard or is located on a separate plume under the screen.
