The situation where the screen of Xiaomi smartphone refuses to turn when viewing photos or videos is familiar to many users: You take the device in your hands, turn it horizontally, but the image remains vertical, often with black fields on the sides. This can be annoying, especially when you need to consider the details of the picture or comfortably watch the video.
In most cases, reporting that orientation is blocked is not a sign of a major breakdown, most often the problem lies in the software settings of the MIUI or HyperOS operating system, or in the accidental activation of the screen fixation function, but there are more complex scenarios associated with the operation of hardware sensors.
In this article, we will discuss in detail why Xiaomi ignores the position of the case, how to force the screen to turn on, and what to do if standard methods do not help.
Main reason: Locking sensors in the notification curtain
The most common, but most common, reason is the activated orientation fixing function, and in the MIUI and HyperOS shells, this is controlled in the control center, and if you see a lock or arrow icon in a circle that is lit in blue or white, then the rotation of the screen is forced to be disabled by the system.
To unlock orientation, you lower the notification curtain from top to bottom. Find the autorotation icon. In different versions of firmware, it can be called "Orientation", "Autoporate" or "Orientation Lock", and clicking on this element should change its state to active (unlocked).
It is worth noting that in some use cases, such as watching certain video formats or reading books, the application can ignore system settings and impose its display mode.
โ ๏ธ Note: If the switch in the curtain is inactive (gray) or absent, this may indicate a system process failure or conflict with the installed design themes.
Check to see if Do Not Disturb or Power Saving is on, as in extreme charge saving modes, the system may restrict the background services responsible for tracking the position of the sensors, and disabling these modes often returns full functionality to the interface.
How does the accelerometer and gyroscope work in Xiaomi
The hardware components that determine the position of the device in space are: the accelerometer and the gyroscope; the accelerometer measures acceleration; the gyroscope measures the angle of inclination; and when you turn the phone, these sensors send signals to the processor, which tells the operating system to rearrange the image.
If the Gallery has a lock on orientation, even though the switch in the curtain is off, it's possible that the sensors are not working properly. This can happen after a device falls, a strong impact, or a software failure, when the calibration data is lost.
There's an engineering menu in Xiaomi to test the sensors, so you can run diagnostics to see if it's responding to your movements, and if the sensor is dead or has random values, the software settings won't help, you'll need repairs.
How to log into the engineering menu to check sensors
It is important to understand the difference between software locking and physical malfunction: in the first case, it helps to reboot or reset settings, in the second - only service, and users often confuse these concepts, trying to "cure" a broken sensor with firmware.
Gallery Application Settings and System Limitations
The Gallery app from Xiaomi has its own display settings that can overlap common system settings. Some versions of the shell add a feature called โFixing Orientationโ inside the app itself, designed to make it easy to view albums without random turns.
To check your settings, open the Gallery, go to Profile or Settings (usually a human icon or gears).Look for items related to viewing, slideshow or orientation. Disabling the options of "Fix orientation" or "Turn only in landscape mode" can solve the problem.
Also, some image formats have embedded metadata (EXIF) that tells the device exactly how to display the file. If the photo is taken with a metadata error, the Gallery can stubbornly hold it vertically, ignoring the turns.
There are also system restrictions for certain applications: If you use third-party software rather than a standard Gallery (like Google Photos or QuickPic), check the permissions of this application. Lack of permission to use motion sensors can lead to a turn-block.
Methods of program calibration of the accelerometer
If the hardware sensors are working properly, but they're not working properly, they need software calibration, which is a process where the system re-detects zero, the position where the phone is flat, and without that step, the turn may be delayed or not triggered at all.
There are several ways to calibrate an accelerometer on Xiaomi, the easiest one is through the engineering menu mentioned above, and the more complex but effective one is using hidden codes or special calibration apps from the Google Play store.
Here is a step-by-step instruction for calibration through the engineering menu:
- ๐ Open the Phone app and dial the combination ##6484##.
- ๐ In the list of tests, find the item โAccelerometerโ and click on it.
- ๐ฑ Place your phone on a completely flat horizontal surface with the screen up.
- โ Click the Calibrate button and wait for the process to be completed.
- ๐ After successful calibration, restart the device.
โ ๏ธ Attention: Do not calibrate with your phone in your hands. The surface must be perfectly flat, otherwise you will "cheat" the sensor and it will consider the inclined position the norm.
After you restart, check the Gallery. If the problem was the downed accelerometer settings, the screen should start rotating correctly. If the calibration didn't help, maybe the problem goes deeper and concerns system files.
Resetting settings and cleaning the system cache
The accumulation of temporary files and cache can lead to conflicts in the work of system services. The service responsible for turning the screen can โhangโ or work incorrectly due to corrupted temporary data. Clearing the cache is a safe way to try to fix the situation without losing personal data.
You need to go to your phone's settings, find the Apps section, then select All Apps. In the list, look for Gallery and SystemUI (or SystemUI), and for each, select Clear Cache and Clear Data.
Donโt be afraid to clean up the system application data of the interface โ it wonโt delete your photos or contacts, it will only return the display settings (wallpaper, icon layout, curtain settings) to factory values, which often eliminates software glitches.
โ๏ธ Checklist before resetting settings
If cleaning the cache didn't help, you can try a more radical method - resetting all the phone settings.This step will remove all the data from the device, so be sure to make a full backup before you start.Reset eliminates any software errors that may have accumulated over the time of use.
Third-party orientation management applications
When MIUI's built-in tools fail, third-party solutions come to the rescue, and there are many utilities available in the app store that force the display to control the orientation of the screen, ignoring system locks, which is especially useful for older models or devices with buggy firmware.
Popular apps like Rotation Control or Ultimate Rotation Control allow you to create profiles, and you can set the rule: "For the Gallery app, always turn on autorotation," even if the system switch is off.
Installing this app gives you full control of the sensors, so you can assign hotkeys to switch modes quickly, or set up automatic orientation modes when you open certain programs.
However, third-party software has its own risks: applications that require special permissions (through ADB or root rights) to intercept screen control, and inexperienced users should be careful about granting such rights.
Table of possible causes and solutions
So for the sake of diagnostics, we've created a table that can help you quickly identify the problem and find a solution, and use it as a checklist for troubleshooting.
| Symptoms. | Probable cause | Method of decision |
|---|---|---|
| The screen doesn't turn anywhere. | Locking in the curtain is on. | Disable โOrientationโ in the control center |
| Turning is working with a delay | Failure of calibration of the accelerometer | Calibrate in the Engineering Menu |
| It doesn't turn around in the gallery. | App settings or cache | Clear the Gallery app data |
| Screen 'twitches' when turning | Sensor malfunction or magnetic field | Remove the magnetic case, check the sensor |
| Problem after software update | Firmware bug MIUI/HyperOS | Wait for a patch or install third-party software |
๐ก
Use magnetic cases with caution. A magnetic fastener placed next to the sensors can drive the accelerometer crazy, causing random turns of the screen.
If none of the software methods worked, and the sensor shows zero values or does not respond to movement in the engineering menu, it is a physical failure, in which case you will need to replace the plume or module of the accelerometer in the service center.
