Control of the screen orientation on Xiaomi Redmi Note 8

Modern smartphones like the Xiaomi Redmi Note 8 feature advanced sensors that automatically change the position of the image on the display depending on how you hold the device in your hands.This feature, known as autorotating or screen orientation, is critical for comfortable video viewing, reading books or playing horizontally. However, users often face situations where the screen “frozen” in an upright position or, conversely, flipped at the most inopportune moment.

Understanding the accelerometer and gyroscope inside your gadget will not only help you set up your system correctly, but also help you quickly diagnose possible hardware failures. In the MIUI operating system, which is installed on the Redmi Note 8, these parameters are managed through several menu levels, which sometimes causes confusion for beginners. We will analyze all available control methods, from standard switches to hidden engineering tests.

In this article, you will find detailed instructions for turning on, locking and calibrating position sensors. We will also look at typical software conflicts that can block the rotation of the interface in specific applications.

The principle of operation of position sensors in Redmi Note 8

The automatic image rotation function is based on the complex operation of several physical sensors built into the smartphone motherboard, and the main element here is the accelerometer, a microelectromechanical system that responds to changes in the acceleration and tilt of the device relative to the gravity vector, which tells the coordinate system that the phone has been rotated 90 degrees.

The gyroscope provides additional precision in positioning. Unlike an accelerometer that measures linear acceleration, a gyroscope tracks angular rotation. Collaborating data from these two sensors allows the MIUI to rotate smoothly and without delay, ignoring the slight jitters of the hand. If one of the sensors fails or malfunctions, the autorotation function can behave chaoticly.

It's important to understand that software plays just as much a role as hardware. The Android operating system in conjunction with the Xiaomi shell constantly polls sensors. When there is a load on the processor or errors in the drivers, the signal from the sensor simply does not reach the interface, which causes the screen to stop responding. The critical point is that the software failure of the sensor can often be corrected by calibrating without contacting the service.

⚠️ Attention: Frequent smartphone falls can cause physical damage to the accelerometer chips.If the screen stopped turning after impact, software methods may not help.

The main ways to turn on and block the turn

The fastest and most common method of controlling the orientation of the screen on the Redmi Note 8 is in the Quick Settings Panel, which requires swipe gestures from the top edge of the display down, and in the menu you open, you need to find an icon with the image of the lock or arrows, which is signed as "Orientation" or "Autoporot".

If you don't have a standard icon on the first screen, you should press the edit button (usually a pencil icon or three dots in the corner) and drag the necessary control to the active zone. The logic of the switch is simple: when the function is active, the screen responds to turns; when it is off, the position is fixed. This is convenient, for example, when reading lying down, when the random tilt of the head or body should not change the picture.

The alternative is through a deep system settings menu, where you can not only enable the function, but also check if any access restrictions are activated for specific applications. The path usually looks like: Settings → Screen → Screen Autoturn. In some versions of MIUI, this item can be entered in the section "Extended settings".

There is also a hidden option to control through a special feature menu, which can be useful if the touchpad is not working properly. Activating the special feature menu allows you to display a floating ball on the screen through which you can duplicate the rotation functions, this is especially true for users with disabilities or temporary problems with the touchscreen.

Setting up screen settings in the MIUI menu

The MIUI shell provides advanced customization capabilities that affect interface behavior. In the screen settings section, you can find parameters that determine font size and image scale. It's important to know that when you set a very large scale or a non-standard font size, some applications may ignore the rotating command, because the layout of their interface is not adapted to horizontal mode in such settings.

One of the things that deserves a special attention is the One-Hand Mode feature, which can also conflict with orientation. When this mode is activated, the screen shrinks and shifts into an angle, which sometimes blocks the gyroscope for the main window. You can check these settings by going to Settings → Additional Settings → One-Hand Mode. Make sure that this mode is turned off if you're trying to diagnose rotation problems.

Another important aspect is screen refresh rate and dark theme. Although they don't directly control the turn, using a dark theme in some older apps can cause visual artifacts when changing orientation. It's recommended to keep display drivers updated through Xiaomi system updates, as the company's engineers regularly release patches that improve the stability of the graphical interface.

💡

Use a dark theme with caution in older apps – it can cause delays when redrawing the screen during a turn.

To make the settings more subtle, you can use the Developer Menu, which is entered by repeatedly tapping the build number in the About Phone section, where you can find items related to the animation of windows and transitions, and speeding up animation can make the screen turn visually faster, even though the sensors are physically working at the same speed.

Solving problems with autoturn through the engineering menu

If standard methods don’t work and the screen on the Redmi Note 8 stubbornly refuses to turn, you need to resort to deeper diagnostic methods. Xiaomi smartphones have a special CIT (Customer Integration Test) engineering menu designed to check all components of the device, accessed through a set of code in the phone book.

To enter the test mode, dial ##6484#. In the test list that opens, you need to find the item associated with the accelerometer (usually called the Accelometer or has a corresponding icon). When you run the test, you will see three graphs or numerical values that change in real time when the phone is tilted.

If the test mode values do not change or change in jerks, this indicates a hardware problem or a need for calibration. In some versions of the engineering menu, the Calibration button is available. When you press it, you put the phone on a perfectly flat horizontal surface and wait for the process to be completed, which resets the current sensor readings to factory zero values.

⚠️ Note: Do not change other parameters in the engineering menu unless you are sure of their purpose. recalibration of other sensors (for example, proximity or magnetometer) can disrupt call and navigation.

After calibration, be sure to restart the device. The usual reboot through the menu is enough, but in difficult cases, it is recommended to perform a full cycle of switching off and on. CIT-menu problem persists, most likely the case is in a software conflict of installed applications or damage to the module plume.

The Impact of Third-Party Applications on Orientation

Often, third-party applications that intercept sensors are responsible for incorrect screen behavior. Launchers, reading apps, video players, and games can force their orientation to ignore system settings. For example, a book reader app can block the rotation even if the system is on autorotating to prevent accidental page changes.

There are special permissions in MIUI to manage this behavior. Go to Settings → Applications → All applications, select a problem application and find the "Allowances" or "Additional permissions" section. This can be "Changing the orientation of the screen" or similar. By disabling or turning it on, you can force the application to obey system rules.

There are also specialized tools from the Google Play store, such as Rotation Control or Ultimate Rotation Control, which create an overlay (a layer on top of other windows) that dictates how to behave with orientation, which is useful if the usual means do not achieve the desired result, but they should be used with caution, because they consume battery resources.

App cache: Accumulated errors in the program can block correct processing of turn events. Clearing the cache through the application management menu (“Storage” → “Cache Clear”) often solves the problem of sudden interface failures to respond to user actions.

Comparison of orientation behavior in different applications

The behavior of the autorotation function can vary dramatically depending on which application is running at the moment. Xiaomi system applications (Gallery, Explorer, Settings) usually work consistently and predictably. However, third-party software can make its own adjustments. Below is a table showing the typical behavior of different categories of applications on the Redmi Note 8.

As you can see from the table, social networks often ignore user attempts to turn the main interface, as their design is sharpened for vertical content consumption. At the same time, browsers and video players rely entirely on Android system settings. Understanding this logic helps not to look for non-existent breakdowns when Instagram refuses to turn horizontally.

This is a very special situation for games, because many games today use their own positioning algorithms to prevent accidental palm edge pressing when you turn, and if you notice that the game crashes when you turn the screen, try to find Lock Orientation in the game's settings and manually lock the desired mode.

💡

Different app behaviors are normal operating system, not smartphone defects. Each application takes priority over sensor management.

Additional recommendations and sensor maintenance

To keep all Redmi Note 8 features running smoothly, including screen orientation, it is recommended to periodically prevent software. Updating to the latest available version of MIUI ensures that you get bug fixes that may have been detected by developers in the accelerator.

If you use protective covers, make sure they are not too thick and do not press on the body in the locations of the sensors. Although the accelerometer is inside the board, severe deformation of the case or magnetic inserts in the case (used to attach to the car holders) can interfere with the magnetometer, which is also involved in determining the position in space.

If no software methods help and there are obvious failures in the engineering menu, it is likely that a module replacement is required. In the Redmi Note 8, the accelerometer is often soldered on the main board or is part of a composite module, which requires qualified repair in the service center. Self-replacement without experience can lead to damage to the plumes.

⚠️ Attention: Magnetic car holders may temporarily demagnetize or knock down the calibration of the compass and gyroscope.

Timely cleaning of the phone memory also has a positive effect on the reaction speed of the interface: overcrowded drive causes the system to work slower, which can manifest itself in the form of lags when you turn the screen. Try to keep at least 10-15% of the total internal memory of the device free.
