When the screen turns on Xiaomi, it can be taken by surprise at the most inopportune moment: watching a video, reading long articles or playing. Instead of smoothly turning the image, the display stubbornly stays in portrait orientation, ignoring the physical rotation of the smartphone. This is not just a minor inconvenience, but a serious failure in the work of the accelerometer or software that requires immediate intervention.
The problem can be a simple software error of the MIUI interface, and hardware damage to internal sensors after a fall. Users often panic about expensive repairs, but in most cases you can return the functionality yourself in a few minutes, you need to sequence the settings of the system and check the operation of the sensors.
In this article, we will take a look at all possible causes of malfunction and offer step-by-step instructions for fixing them, learn how to perform deep calibration, reset to factory values without losing data, and determine when it is time to carry the device to the service center.
Primary diagnosis and verification of basic settings
Before you go to complex manipulations, you need to rule out basic user errors. Often, the rotating function is simply locked in the notification curtain or the mode that forcibly fixes orientation is activated. Check the top control panel: there should be an icon with a lock or arrows that activates or deactivates the orientation lock.
If the slider in the curtain is not active, but the screen is still not responding, it is worth checking the settings of the application itself. Some programs, especially video players and browsers, have their own internal settings that can overlap the system settings of Android. Make sure that the specific application does not tick “Fix orientation”.
Also, you should consider that on the desktop (launcher), the turn may not work by default in some versions of the firmware. This is the standard behavior of the system, designed to keep the navigation of icons easy. Try to open a gallery or YouTube — if there is a turn, then everything is fine with the hardware.
⚠️ Warning: If the screen is turning in jerks or with a large delay, this may indicate a software conflict of a newly installed application that intercepted the control of the sensors.
To quickly check the status of the sensors, you can use the engineering menu. Enter the code ##6484## in the Phone app. In the menu that opens, select "Accelerometer" or "G-sensor." Try to tilt the phone - values should change in real time.
Calibration of the G-sensor through the engineering menu
If the basic diagnostics show that the sensor is responding but is not responding correctly, it requires a calibration of the G sensor, a procedure that trains the smartphone to determine where the top and bottom are when horizontal, and without that setting, the accelerometer may mistakenly assume that the phone is already upside down.
To start calibration, go back to the engineering menu with code ##6484##. Find the section associated with the accelerometer. Before you start the process, put your phone on a perfectly flat, hard surface. This is critical, because any tilt on the table will be perceived as zero by the system.
Press Calibrate or Start. The system will ask you to flip the device over several times or simply wait for the automatic setup to be completed. In the process, don't touch the smartphone or create vibrations. Once successful, the message will appear "Pass" or "Success".
☑️ Checklist of correct calibration
In some cases, standard calibration may not pass the first time. If you get an error, try repeating the procedure by first clearing the back cover of the case. Thick protective accessories can create additional pressure on the body, distorting the readings of the sensors.
💡
If standard calibration doesn’t help, try to do it in the position in which you most often use your phone horizontally (like lying on the couch), but strictly on a flat surface.
Resetting accelerometer settings and resetting to factory
When software calibration fails, more radical measures are taken: resetting accelerometer settings often helps to eliminate software errors accumulated in the cache of system services. It doesn't delete your personal data, but returns sensor parameters to their original state.
To perform the reset, go to Settings → Advanced Settings → Recover and Reset. Note: you don’t have to choose a full phone reset. Look for the option “Reset sensor settings” or similar if your version of MIUI supports this feature separately, otherwise cleaning the cache of Google Play services will help.
If the problem is systemic and affects the entire interface, a full Hard Reset may be required, which is an extreme measure that will delete all data.
| Resetting method | Data retention | Efficiency | Risk of data loss |
|---|---|---|---|
| Calibration on the menu | Complete. | Medium | No. |
| Cleaning up the app cache | Complete. | Low. | No. |
| Resetting (Soft Reset) | Partial | Tall. | No (settings only) |
| Full reset (Hard Reset) | No. | Maximum | High (all removed) |
Once you reset, the system will restart. The first few minutes of the smartphone can be slow, as you index files and configure services. Don't try to check the screen's rotation right away, let the system start completely.
Updating the system and searching for conflicts
Often the cause of incorrect operation of the autorotation are bugs in the current version of the firmware. Xiaomi developers regularly release updates that correct errors in working with iron. Check for updates in the Settings menu → About the phone → MIUI version.
If you are using a global firmware version but have reflashed your device to Chinese (or vice versa), there may be driver conflicts, in which case it is recommended to return to the stock firmware for your region.
It’s also worth analyzing whether you’ve recently installed gesture control apps, screen blockers, or memory accelerators, which often require deep resolutions and can intercept sensor control by blocking standard Android features.
⚠️ Note: Installation of firmware from unverified sources (custom) ROM) can permanently disrupt the operation of sensor calibration tables, if you do not backup the original partitions.
Try to start your phone in Safe Mode, press the shutdown button, and then hold your finger on the Turn Off button on the screen for a long time, and if you're in Safe Mode, it's the third-party app that's to blame.
What is a safe regime?
Hardware problems and physical damage
If the software didn't work, there's a high probability of hardware failure, an accelerometer is a microelectronic component that can fail due to impact, fall or moisture getting inside the case, and even if the phone is intact, the internal chip could have moved away from the board.
A common cause is the unplugging of the plume or oxidation of the sensor contacts. In models with a glass back cover, the impact can lead to microcracks in the sensor structure. In such cases, the software calibration will return an error or show zero values regardless of position.
It's also worth checking if the device is overheating. At critical temperatures, the system can force some sensors to shut down to prevent damage. If the phone is hot, let it cool down and check the function again.
Diagnostic problems are better done in a service center, specialists will open the device, check the voltage on the contacts of the accelerometer and replace the module if necessary, self-repair without experience can lead to a complete failure of the smartphone.
💡
If calibration and reset do not help, and in the engineering menu the sensor shows static values - the problem is physical, a replacement of the accelerometer module is required.
Specificity of work in applications and browsers
Special attention should be paid to situations where the screen does not turn only in applications, such as in the Chrome browser or Mi Video. Browsers often activate the "Mobile version", which forcibly keeps the portrait orientation for easy reading.
Video players can lock the landscape mode. Check the settings of the application itself: often there is a button with two arrows or a lock. In some cases, cleaning the cache of a particular application through Settings → Apps → All Apps → [Title] → Clear helps.
For some games, the developers didn't have horizontal mode, and no phone settings will make the image turn.It's a limitation of the app's program code itself, not a malfunction of your Xiaomi.
If you use third-party launchers (Nova, Launcher 7, etc.), make sure their settings allow desktop rotation.The standard MIUI launcher can block a turn on the home screen, whereas third-party ones allow this to be configured more flexibly.
