Xiaomi smartphone users often face a situation where when you rotate the device, the image on the display remains unchanged, and at the top of the screen or in the notification curtain appears a small lock icon. This symbol indicates the activation of locking the orientation of the screen, which prevents the interface from automatically turning from a vertical position to a horizontal one. For many Mi and Redmi owners, this comes as a surprise, especially when trying to watch a video or easily type text with both hands.
Understanding how automatic rotation works and why it should be blocked is critical to the comfort of the gadget. The MIUI or HyperOS system installed on the device uses accelerometer and gyroscope data to determine the position of the case in space. However, software constraints can block these signals, creating the illusion of a malfunction, when in fact it is a regular feature designed to protect the user from accidental changes in the interface.
In this article, we will discuss in detail why the orientation icon appears, when it is useful and when it interferes, and how to manage it correctly. We will look not only at standard methods of disconnecting through the notification curtain, but also at deeper system settings that can be hidden from the average user.
Functional purpose of the lock icon
The icon, often referred to by users as the “orientation icon,” is actually a screen-turn-blocking indicator. When that symbol is active (usually illuminated or with a color background), the system forcibly keeps the interface in its current orientation, ignoring the physical actions of the user as the smartphone rotates. It is a useful feature that prevents random switching between portrait and landscape modes when you lie on your side or hold the phone at an uncomfortable angle.
In the Android operating system, on top of which the Xiaomi shell is built, orientation management is a system priority. The position sensor is constantly polled by background processes. If the lock is removed, any tilt of the device more than 45 degrees initiates a redrawing of the graphical interface.
It is important to distinguish between system lock and application-specific constraints. Some programs, such as bank clients or specialized utilities, can force the display to fix the orientation of the screen regardless of the phone settings. In such cases, the icon in the curtain may be missing, but the screen will not rotate. However, if you see an active lock indicator in the status bar, this means that the function is turned on globally for the entire system.
⚠️ Warning: The lack of screen response to turn when the lock icon is off may indicate a physical malfunction of the accelerometer or gyroscope, especially if the phone has recently been hit.
💡
If the lock icon appears on its own after a reboot, check the installed cleaning apps or optimizers – they can force this feature to save energy.
How to turn on and off autoturn on Xiaomi
The screen orientation management in Xiaomi smartphones is implemented as simple and accessible as possible through the control center. Depending on the version of the MIUI shell or HyperOS, the appearance of the elements may vary slightly, but the logic of the work remains the same. The user does not need to climb into deep engineering menus, since the developers have brought this feature to the first level of interaction.
To quickly access the settings, you need to unlock the device and swipe from the top edge of the screen down. The icon menu that opens should find an element that depicts the lock or arrows forming a circle. In newer versions of the firmware, this switch is often labeled "Orientation" or "Autoporot", clicking on it changes the status of the function: if the icon is lit in blue or white, the lock is on (the screen is not rotating), if the gray, autorot is active.
There is also an alternative way to control through system settings, which can be useful if the touch screen is temporarily unresponsive or the icon is removed from the curtain. To do this, follow the path: Settings → Screen → Screen Orientation. Here you can not only switch mode, but also configure additional parameters, if they are available in your version of the software.
☑️ Checking the auto-turn settings
It's worth noting that in some use cases, such as when you run a video player or a camera, the system can ignore the lock and force the device to landscape mode, which is a standard behavior that can not be considered a mistake, but for most menus and applications, reading text, the lock will act strictly according to the user's settings.
Configure the controls in the notification curtain
A common problem for users is that the switch disappears from the quick access. MIUI allows you to flexibly adjust the contents of the control center by adding or removing function shortcuts. If you can't find the orientation icon, chances are it's just hidden or moved to the area of inactive elements.
To return the button to its place, you need to pinch your finger on any blank spot of the notification curtain or click on a special edit icon (usually looks like a pencil or gear in the corner of the menu). An editor will open, where all available switches are divided into two groups: "Upper" (active) and "Lower" (available). You need to find the "Orient" or "Blocking the Turn" item in the bottom list and drag it to the active zone.
Once the changes are saved, the icon is guaranteed to appear in the curtain, especially after major system updates, when Xiaomi can reset user interface settings to factory values. Regularly checking the composition of the curtain helps keep the most important features on hand.
In addition, in the display settings, you can change the size of the icons or their location, which can affect the ease of getting a finger. For people with large motor skills, it is recommended to take the frequently used switches to the top row, closer to the thumb.
Table of orientation indicators states
To better understand how the system works, it is useful to know how the different states of sensors and locks are visualized. Below is a table that will help you quickly navigate the values displayed on your Redmi or Poco screen.
| The look of the badge | Status of the system | Turn reaction | Where it's displayed |
|---|---|---|---|
| Castle (colored/active) | Lock on. | The screen doesn't turn. | Status line/Stork |
| Lock (gray/inactive) | Lock off. | The screen turns. | Only in the curtain. |
| Two arrows (round) | Auto-turn mode | Automatic shift | Curtain (old versions of MIUI) |
| Absence of a badge | Depends on the app. | Defined by the programme | Not showing. |
Note that different versions of the shell may have different graphical designs, with MIUI 12/13 often using a lock symbol, whereas earlier versions used arrows. HyperOS designers have returned to a minimalist lock image that clearly signals a ban.
If you see an icon but it behaves unpredictably (e.g., flashes or changes color without you being involved), this could be a sign of a software conflict, in which case it is recommended to check for system updates or reset the interface settings.
Sensor problems and screen calibration
Sometimes the orientation icon works correctly, but the screen itself stops responding to the device’s turns even when the lock is removed, indicating problems with hardware sensors such as the accelerometer or gyroscope. Xiaomi smartphones have a hidden engineering menu to diagnose and calibrate these components.
To enter the test menu, you need to open the Phone app and dial a special code: ##6484##. Once you enter the combination, the CIT menu will open. In the test list, you need to find the item associated with the accelerometer (usually called Accelerometer or G-sensor). Following the instructions on the screen, you will need to put the phone on a flat surface and press the calibration button.
What to do if calibration doesn’t help?
It is important to calibrate only on a perfectly flat horizontal surface. Any table tilts or vibrations can lead to incorrect data that will be recorded in the memory of the controller. After successful calibration, you need to restart the device to make the changes take effect.
If after all the manipulations, the orientation icon is on, but the screen is not rotating, or vice versa, it is worth checking whether the screen is not glued to a protective glass of poor quality. Some thick glasses can create mechanical pressure on the sensors or shield their operation, although this is rare.
⚠️ Note: Do not try to calibrate the sensors while holding the phone in your hands. To accurately operate the accelerometer, the device must lie motionless on a hard surface during the process.
The Impact of Third-Party Apps and Launcher
Don’t discount the impact of third-party software: Desktop launchers, weather widgets, or gesture control apps can intercept screen orientation control, for example, some launchers have their own turn lock setting, which is prioritized over the system.
If you notice that the orientation icon only behaves strangely in certain applications, check their individual settings. Video players, book readers and browsers often have their own turn button inside the interface, which ignores the system settings. In such cases, the icon in the curtain may remain in the "locked" position, but the video will play to the full screen.
Conflicts can also arise when using screen recording or remote access applications, which can force orientation to ensure the stability of the image broadcast, and if a problem occurs after installing a new program, try removing it or checking permissions in the Settings → Apps → Rights section.
💡
Application conflict is one of the most common causes of autorotation malfunctions, so check which programs have access to screen control.
In rare cases, the culprit is malware or adware embedded in the system. If the orientation icon appears on its own and the phone begins to behave suspiciously, it is recommended to conduct a full antivirus check and remove the recently installed dubious utilities.
