When the display of a Xiaomi or Redmi smartphone refuses to change orientation when turning the case, it is quite common and can seriously complicate watching videos or reading documents. Users often find that the usual autorotation function ceases to respond to actions, causing the screen to remain in an upright position contrary to expectations.
The reasons for this behavior can be quite different: from the banal locked setting in the notification curtain to the hardware failure of the accelerometer. In the shell of MIUI and the new HyperOS, sensor management is implemented with its own features that are not always obvious to beginners who have switched from other brands.
In this article, we will take a look at all possible scenarios, explain how to calibrate sensors correctly and what to do if a software reset does not work, learn what hidden settings can block the turn and how to check the hardware without visiting the service center.
The main reasons for blocking the turn of the screen
The first thing to rule out is software locking. In modern versions of Android, orientation control is brought to the control center, and often users accidentally activate position fixation without even noticing it. On Xiaomi devices, this switch can be called “Orientation” or “Autoporot”, and its state is more important than any other settings.
The second common reason is that a particular application works, and many programs, especially social networks or specific utilities, are blocked vertically by the developer, and in such cases, the system does not "glue" but simply tells the application to ignore the gyroscope data for the given window.
⚠️ Note: If the screen stops rotating in only one app (for example, YouTube or Gallery), check the settings of the application itself.
Cheap protective films with thick edges or improperly installed glass can create micro-voltage on the body, which in rare cases affects the sensitivity of embedded position sensors. In addition, magnetic mounts in cars can temporarily knock down the readings of the magnetometer, which is involved in determining the position of the device in space.
Checking the settings of the MIUI and HyperOS interface
MIUI and HyperOS interfaces have their own features for displaying controls. To make sure the function is activated, you need to lower the notification curtain down. The icon can look like a lock with circular arrows or just like a smartphone with arrows around. If the icon is illuminated, the autorotation mode is turned off.
In some cases, changing the display settings helps. Go to the settings menu and find the section that's responsible for the screen. There may be "Element Size" or "One-Hand Mode." Activating one-handed control mode often blocks the interface from turning so as not to disrupt the ergonomics of use.
For a deeper check, you can use the engineering menu that is built into Xiaomi phones, which will allow you to see if the system sees the fact of the device turning, even if the interface does not respond.
☑️ Diagnostics of screen settings
If you don't find a switch in the standard menu, try searching by settings. Type the word "rotation" or "orientation" in the search bar under "Settings." The system will suggest the right shortcut, even if it's hidden in the bottom of the menu, which is especially true for global firmware versions where localization can be inaccurate.
Calibration of sensors through the engineering menu
When the software settings are fine, but the screen is not responsive to the change in body position, the accelerometer and gyroscope are calibrated. Redmi and Poco have a hidden engineering menu available through code in the "bell ringer," which is the most efficient way to return sensors to sensitivity.
To enter the diagnostic menu, dial the combination ##6484##. If the code does not work, try ##4636##. In the list that opens, select "Single item Test" or immediately search for "Accelerometer". Before starting the procedure, you must put the phone on a completely flat horizontal surface.
The calibration process is this: when you run the test, the numbers will appear on the screen; you have to put the phone flat on the table and wait for the numbers to stabilize; then you have to put the phone on the edge and put it flat again; if you do that, you can then click on the Pass or Calibrate button.
| Parameter | Normal (rest) value | Calibration action | The result |
|---|---|---|---|
| X-Axis | About 0. | Turn left/right | Change of values |
| Y-Axis | About 0. | Turn up/down | Change of values |
| Z-Axis | About 9-10 (gravity) | The flat position | Stabilization |
⚠️ Attention: Don't calibrate with your phone in your hands. The slightest shaking will distort the data, and the sensor will work incorrectly, counting the slope where there is none.
After successfully calibrating all available sensors (including the gyroscope and magnetometer), be sure to restart the device. The system must read new base values and apply them to the correct operation of the interface. If the numbers in the test “jump” randomly even on the table, it may be physically damaged.
What to do if the engineering menu is not opened?
Third-party orientation management applications
If Xiaomi’s regular funds fail, third-party solutions from Google Play come to the rescue. Orientation control apps can force landscape mode to be enabled even in programs where it is blocked by the developer. This is a great temporary solution while you search for the cause of the failure.
One of the tools that's popular is Rotation Control, which intercepts system commands and makes the screen rotate according to the rules you set, and then you give the application the permissions you need and activate it through the notification panel.
Another option is to use macros or automation apps like MacroDroid, where you can create a scenario where you can say, "If you have a YouTube app, turn it on automatically," and you can flexibly customize the behavior of the screen for specific tasks without relying on the standard, sometimes buggy, algorithm of the system.
- 📱 Rotation Control: Allows you to force-fix or allow rotation for any application, ignoring system limitations.
- 🔄 Ultimate Rotation Control: Has more subtle sensitivity settings and the ability to create profiles for different situations.
- ⚙️ MacroDroid: A powerful automation tool that allows you to link a change in orientation to the launch of specific programs or time of day.
However, for devices with “capricious” sensors, this is often the only way to comfortably use a smartphone in horizontal mode.
Hardware problems and the impact of updates
You can't discount the physical damage. If the phone has recently fallen, even from a low altitude, the Hall sensor or the accelerometer may have shifted or moved away from the plume, and in such cases, the software calibration only gives a temporary effect or does not help at all.
Problems also often arise after updating the firmware MIUI or HyperOS. Newer versions of Android change hardware drivers, and old configuration files may conflict with new settings. That is why after a major update, it is always recommended to do a full reset, although users often ignore this rule.
💡
If calibration and third-party applications do not help, and the phone fell, a hardware fault of the sensor is likely, requiring a replacement of the module in the service.
Another nuance is that the device overheats, and when the processor and other components are under heavy load, they heat up, which can lead to unstable sensors. If the screen stops turning only during games or long navigation, let the device cool. Thermoregulation in Redmi smartphones sometimes aggressively restricts the peripheral operation to protect the hardware.
