Modern smartphones like the Xiaomi Redmi 9 have a lot of sensors that make it easier to use, such as the accelerometer, which changes the orientation of the display, which is useful for watching videos or reading books, but sometimes it gets in the way.
For example, when lying down, the phone can suddenly turn the picture around, confusing the user, which is why the question of how to turn off the autorotation on the xiaomi Redmi 9 remains relevant for many owners. In this article, we will discuss all the available ways to control this function.
You'll learn not only about standard locking techniques, but also the intricacies of system sensors, and understanding how they work will help you manage your device more effectively, and we'll look at the standard MIUI shell and third-party solutions for complex cases.
Standard way to block through the notification curtain
The fastest and most obvious method to capture the position of the screen is hidden in the control panel. On Xiaomi devices with a MIUI shell, this control is put in a prominent place. You don't have to dig into the deep settings menu to solve the problem.
Just swipe down from the top of the display to open the control center. Depending on the firmware version, the icon may be called "Orientation" or "Autoturn." Click on it to change the status of the feature. If the icon is on blue or orange, the mode is active.
In some versions of the interface, the switch logic is inverted. Orientation locking can be a separate button with a lock icon. In this case, the active state (lock closed) means that the screen will not respond to the device's turns.
⚠️ Attention: If the screen is still spinning after pressing the button in the curtain, it may have been at the software or sensor level, in which case simply switching the toggler will not help.
For users who often change their phone position, the convenience of this method is obvious. However, it requires doing something every time you pick up the device. Is there a more reliable solution? Let's look at the alternatives.
Configure the autoturn through the system menu
If fast access through the curtain for some reason does not work or is not available, you can always use the basic settings of the system, this method ensures that you are acting on the global setting of the device, not on the temporary switch.
Find the Settings app on your desktop and run it. In the category list, you'll need to find the section related to displaying information. The path may vary slightly depending on the version of MIUI, but the logic remains the same.
- 📱 Go to the screen or display section».
- 🔄 Find the item “Screen orientation” or “Ship turn».
- 🔒 Switch the slider to the right position to lock.
- 📂 Alternatively, check the section "Advanced settings».
This is where the main system switch is, which controls the response of the accelerometer in all applications at once, the changes take effect instantly, and then the phone will no longer respond to the change in its position in space.
It's worth noting that newer versions of MIUI 12 and MIUI 13 sometimes hide this item deeper. If you don't find it in the Screen section, try searching by settings. Type the word "turn" into the top of the search bar, and the system will show you the way.
☑️ Checking the display settings
Use of the Security App and Google Services
Many users forget that Xiaomi’s standard Security app contains many hidden optimization tools. Although there is no direct lock, resetting sensor settings through this app can solve the problem of malfunction.
And Google's system services are also a must: In some cases, the conflict between Google Play services and the MIUI shell leads to autorotation living its life.
Consider the main steps for diagnosis through system utilities:
- 🛡️ Launch the Security app from the Tools folder».
- 🧹 Select the Cleanup or Accelerate function to reset the cache of processes.
- 🔄 Go to your phone’s settings and check for system updates.
- 📲 Make sure that Google Play services are updated through the app store.
Often the problem is not the function itself, but the background process, which is “glutty.” Restarting services through the security menu helps refresh the system sensors, which is especially true if the phone has not been rebooted for a long time.
⚠️ Note: Do not remove Google system applications or components MIUI, Trying to turn off the autorotor, which can cause the whole smartphone to work in an unstable way.
Third-party orientation management applications
If the standard Xiaomi Redmi 9 methods don’t work well or require too much intervention, apps from the Play Market store come to the rescue, allowing you to create more flexible screen management scenarios.
There are utilities that force you to map the orientation of specific applications, for example, you can set your phone so that the browser doesn't turn the screen and YouTube turns automatically, which gives you maximum control.
Popular management tools:
- 📐 Rotation Control – allows you to force a portrait or landscape mode.
- 🔧 Ultimate Rotation Control is a powerful tool with many settings.
- 📱 Screen Orientation Control is a simple solution for fast locking.
Installing this app will add an extended control menu to your notification curtain, so you can select "Block in Current Orientation" mode with a single touch, which is more convenient than a standard MIUI switch.
Are the screen control apps safe?
Sensor calibration and troubleshooting
There are times when there's a lock button, but the screen is chaotic, and that's a sign that you need to calibrate the accelerometer, and the sensor might have gone off after a fall or a software failure.
For Redmi 9, there is a hidden engineering menu that allows you to check the operation of all sensors, accessed through the code in the Phone application. Dial the combination ##6484## to enter the CIT testing mode.
In the engineering menu, select "Accelerometer" or "Sensor." Follow the instructions on the screen: you usually need to put the phone on a flat surface and press the calibration button, and the system will determine the correct position of zero.
| Problem. | Possible cause | Method of decision |
|---|---|---|
| The screen doesn't turn. | Lockdown on. | Check the notification curtain |
| The turn comes with a delay | Contaminated sensor | Wipe the top of the screen |
| Chaotic change of orientation | Calibration failure | Calibrate in the CIT menu |
| It only works in some games. | Application settings | Check the permissions in the settings |
After successful calibration, restart the device, which will lock the new parameters into the controller's memory, and if the problem persists, there may be physical damage to the sensor.
💡
Before calibration, be sure to remove the protective glass or case if they are thick and can interfere with the free position of the phone on a flat surface.
Frequent questions and additional solutions
Even after studying all the instructions, users may have specific questions, and often the problem is in details that are not obvious at first glance.
Why does autorotating not work in YouTube but works in a gallery? It's because some apps have their own orientation settings that prioritize the system settings, so you have to look for the settings inside the app itself.
Can a safety glass affect the sensor? No, theoretically, because the accelerometer responds to gravity, not to touch. However, if the glass is curved or has defects, it can create micro-tilts that the phone perceives as a command to turn.
Why did the MIUI update disappear?
Does the energy saving regime affect the auto turn?
What if the screen goes off when you turn?
💡
In 90% of cases, the problem is solved by simply calibrating through an engineering menu or resetting the date and time settings that system services sync.
To sum up, it's a solvable task to manage your Xiaomi Redmi 9 orientation, whether it's standard locking, deep tuning or calibration, you can always take back control of your device, and the key is to act consistently.
