Owners of the popular Redmi series smartphones often face a situation where the usual functionality of the device ceases to respond to user actions. One of the most annoying problems is the failure of the automatic image rotation function when the body changes position in space. On the Xiaomi Redmi Note 8 model, which is running the MIUI shell, this malfunction can be caused by both a software failure and improper operation of the built-in sensors.
The lack of response to the device's rotation significantly reduces comfort when watching videos, reading e-books or using navigation maps. The accelerometer sensor responsible for tracking orientation can temporarily stick or give incorrect data due to background processes of the system. In most cases, the problem is solved by software methods without the need to contact a service center.
In this article, we will discuss the algorithms for diagnosing and troubleshooting, how to conduct deep calibration of the hidden menu of the engineering test system and what system conflicts most often block the operation of the gyroscope. It is important to understand that ignoring the problem can indicate an evolving hardware defect, so timely diagnosis is critical.
⚠️ Before you start any system settings manipulation or calibration, make sure your Redmi Note 8 battery is at least 30%.A sudden power outage during sensor resets may cause modules to malfunction in the future.
Diagnostics and basic system checks
The first step in fixing any malfunction is to eliminate basic user errors or temporary software conflicts. Often, the rotating function is blocked not because of a breakdown, but because of activated locking in the notification curtain or third-party software. Check whether the "Do not turn" mode is activated in the control center, which could be activated by a random touch.
It's also worth paying attention to the behavior of the system as a whole. If the MIUI interface is slow or other oddities are observed, the problem can be deeper than just a sensor failure.Rebooting the device in 90% of cases clears RAM and restarts the services responsible for processing data from the accelerometer.
There's an easy way to check if the phone is responding to any change of position at all: Open a gallery or a browser and slowly turn the device around, and if the screen blinks or tries to flip over but comes back, then the hardware is good, and you need to look for an application conflict.
- 🔄 Restart your smartphone in the standard way through the power menu or by pressing the lock button for 10 seconds.
- 🔒 Check the notification curtain: make sure the Orientation icon is not active or blue.
- 📱 Test the work in different applications: YouTube, Gallery, Browser to eliminate the error in one specific program.
If the basic steps didn't work, we'll go into deeper analysis, and sometimes the culprit is a protective glass or a cover that physically interferes with the correct operation of the proximity sensors, indirectly affecting the orientation system.
Configure through the CIT Engineering Menu
The most effective tool for diagnosing and fixing iron problems on Xiaomi smartphones is the built-in CIT (Customer Integration Test) engineering menu, which allows you to test each device module separately, bypassing the standard operating system interface, and this is where you can force the accelerometer test to be run and recalibrated.
No root rights are required to enter the menu, which makes this method safe for the average user, but you should be careful when typing commands, since changing other parameters can lead to unstable phone operation. In the CIT menu, we will only use the section responsible for motion sensors.
The calibration process is to place the device on a perfectly flat horizontal surface, and the system reads the current position as a zero-point etlon, and if the phone had previously considered its normal position to be a 15-degree angle, then after calibration, it will begin to correctly determine the horizon and vertical.
##6484##Enter the combination in the Phone app. Once you enter the last star, the menu will automatically open. Find the "Accelerometer" or "G-sensor" item in the list. Click on it and follow the instructions on the screen: first put the phone flat, then turn it down.
⚠️ Note: During the test accelerometer in the menu CIT Do not touch the table or the surface on which the Redmi Note 8 is located. Even minimal vibration can lead to a calibration error, and the procedure will have to be repeated again.

Resetting sensor and application settings
If calibration didn’t work, it could be that there is a lot of software debris in the system or that the cached data of system applications is in conflict. In the Android operating system that runs MIUI, not only the sensor is responsible for the orientation of the screen, but also the system service, and its forced stop and clearing of data often solves the problem of a “stuck” screen.
You'll need to go to the application settings and find the system component that controls the interface, which can be called differently on different versions of firmware, but most often it's Settings, System Interface, or Google Play Services, which are also involved in geodata processing and orientation.
Cleaning up the data won't delete your personal files, photos or contacts, it will only return the system settings to factory values, resetting any configuration errors, and after that, the phone can behave as if it were first turned on, reconfiguring network and account settings.
- 🗑️ Go to Settings. → Annexes → All applications and find “Settings” (cog icon).
- 🧹 Press "Clear» → «Clear everything" (or "Resetting"), confirm the action.
- 📲 Find the Google Play Services app and follow the “Clear Cache” and “Delete Data” procedures for it».
Once you have done this, make sure to reboot your device completely, and the first run may take longer than usual, as the system will reinitialize all services.

Impact of Updates and Third-Party Launchers
Often, the problem with autorotating on Xiaomi Redmi Note 8 occurs after updating the operating system or installing a new theme. MIUI developers periodically change the algorithms of the sensors, which can lead to bugs in specific versions of the firmware, and third-party launchers that completely replace the standard desktop.
Design themes downloaded from Themes store may contain code errors that block system functions. If the problem occurs immediately after the visual style change, try going back to the standard theme of "Classic" or "Unnamed" and this will eliminate the programming conflict of the interface.
In the case of system updates, the situation is twofold: on the one hand, new software fixes old errors, on the other hand, it can bring new ones, and if the autorotation stopped working exactly after the update, it makes sense to wait for the patch to come out or, if you have the skills, roll back to the previous stable version of the firmware.
| Influence factor | Probability of problem | Method of decision |
|---|---|---|
| A third-party topic | Tall. | Resetting the topic to standard |
| MIUI Update | Medium | Waiting for a patch or reset |
| Third-party launcher | Medium | Removal of the launcher |
| Root rights | Tall. | Full reset (Wipe) |
Check to see if you have gesture or button management apps that can intercept sensor control, which often require deep resolutions and can conflict with Android system services.
💡
Use Safe Mode for diagnostics: press the turn off button, and when the Safe Mode icon appears, click on it. It's only system applications that work in this mode. If the turn is triggered, it's the third-party application's fault.
Hardware malfunctions and physical impact
When software is exhausted, you have to consider physical failure. The accelerometer and gyroscope in Redmi Note 8 are microelectronic components soldered into the motherboard. They're extremely sensitive to impacts, falls and extreme vibrations. Even if the phone is intact, there could be a microscopic disconnection of the contact or damage to the sensor crystal.
Sensors can also be affected by a bloated battery, where the battery is directly under the main modules in the design of the smartphone, and if the battery starts to swell, it puts pressure on the board, which can disrupt the connections of the plumes or the chips themselves, which is a dangerous situation that requires immediate replacement of the battery.
Moisture, even in small amounts, causes the contacts to oxidize. Moisture may not immediately disable the phone, but over time, corrosive processes disrupt the signaling from the sensors to the processor. In such cases, cleaning the board at the service center can help if the oxidation has not gone too far.
- 💥 The phone fell from a height: accelerometer chip may fall off, soldering is required in the service.
- 🔋 Battery bloating: check if the back cover is arched, if you suspect urgently change the battery.
- 💧 Moisture intake: do not dry with a hair dryer, contact specialists for ultrasonic cleaning of the board.
It's hard to diagnose hardware failure at home, and if the CIT menu shows a persistent error or data doesn't change when you're driving, it's likely that the component is physically faulty.
⚠️ Warning: If you notice that the case of Xiaomi Redmi Note 8 is deformed or the back cover has moved away, in no case press the screen and do not try to insert the battery back by force.
Cardinal measures: Resetting and flashing
If none of the above methods work, the last software option is a complete reset, which returns the phone to factory status by removing all user data, applications and settings, and is guaranteed to eliminate any software conflicts as long as they are not associated with damage to the system partition.
Before you do this, make sure you back up your important data. Reset will delete all photos, contacts and correspondence. Once reset, your phone will look like new, and you'll have to reset your accounts and install apps.
In extreme cases, even if a complete reset doesn't work, you may need to flash the device from your computer, which is a more complex process, requiring the use of the Mi Flash Tool utility and official firmware, and the firmware overwrites all system partitions, including those where the sensor calibration data is stored.
Volume Up + Power (to enter Recovery)To enter recovery mode, press both the volume button and the power button on the phone turned off. From the Recovery menu, select Wipe Data, then confirm the action. After the process is complete, select Reboot.
💡
Hard Reset eliminates 99% of software errors, but requires you to back up before starting the procedure.
