Why does not work autoturn screen on Xiaomi Redmi Note 8 T

When the Xiaomi Redmi Note 8 T stops automatically rotating the image, it often takes users by surprise. It would seem that you just put the smartphone on the table or rotated it in your hand to make it easier to watch the video, but the picture remained in the upright position. This is annoying, especially if you are used to instant interface reaction. However, the problem is rarely the hardware breakdown of the display itself.

Most often, the failure occurs at the software level of the MIUI operating system or due to a failure in the accelerometer, the sensor responsible for determining the position of the device in space. Owners of the Redmi Note 8 T face this regularly after updating or installing “heavy” applications from unverified sources.

In most cases, you can fix this yourself by doing a series of simple manipulations in the settings menu, and the key is the right sequence of actions, and if you just turn the slider on and off in the notification curtain, it may not help, and you need to do a deeper diagnostics to rule out software conflicts.

Check basic settings and notification curtains

The first thing to do if the screen is not rotating is to make sure that the function is activated in the system. On Xiaomi smartphones, the control of this parameter is placed in the control center. Often users accidentally block the turn, and the system continues to work in forced portrait mode.

Lower the swipe notification curtain from top to bottom. Find an icon with a lock and arrows that is labeled "Orientation." If it's gray or crossed, it's a turn-around blocked. Click on it to activate. In some versions of the MIUI shell, this switch may be called "Autoporate."

It's also worth checking if Do Not Disturb mode or special profiles are enabled that can block the change in orientation to save battery life.Sometimes third-party launchers intercept the screen control. Make sure the display settings don't have a fixed font size set, which can conflict with the change in orientation of the interface.

• 🔒 Check the position of the orientation lock in the control center.
• 🔄 Restart the device after changing the settings.
• 📱 Make sure that the running application supports horizontal mode.
• 🚫 Turn off In Your Pocket if it is active incorrectly.

Notice how the system behaves in different applications. Some programs, like bank clients or Instagram in the feed, by default only work vertically; you can't force them to turn without using special utilities; if you have a YouTube or browser, the screen turns and you don't have a gallery, it's a problem in a particular application.

Calibration of the accelerometer through the engineering menu

If simple switches didn't help, the sensor calibration was probably a miscalibration. The accelerometer in the Redmi Note 8 T is a sensitive element that can get confused over time in the definitions of gravity. There's a hidden engineering menu available without root rights to fix this.

To get into the testing menu, open the Phone app and type in a special code. Enter the combination ##6484##. The screen will open a list of hardware tests (CITs). Find the listing option "Accelerometer" or "G-sensor." Click on it.

Follow the instructions on the screen. Usually, the system will ask you to put the phone on a flat horizontal surface and press the calibration button. Then the device can ask you to put it vertically or tilt it at a certain angle. Accuracy is critical here: the surface should be perfectly flat, without tilting.

⚠️ Warning: Don't interrupt the calibration process abruptly. If you remove the phone from the surface before the test is completed, the data may not be recorded correctly and you will have to repeat the procedure again.

Once the calibration is successful, the system will give you a message "Pass." Go off the menu and check for autorotation. If the test shows Fail, try repeating the procedure 2-3 times. Sometimes the sensor needs several cycles to stabilize the readings. If the persists error, the sensor may be physically damaged or the train has moved away.

Reset sensor settings through the developer menu

In more complex cases, when the engineering menu is not available or the calibration does not help, you can try resetting the sensors through the developer menu, which allows you to clear the cache of the system services responsible for orientation without deleting the user's personal data.

To activate the developer menu, go to Settings → About the phone. Find the line "Version." MIUI» And press it fast. 7-10 once in a row until the notice "You've become a developer" appears. Then go back to the main settings menu, select "More» → «For developers».

In the list that opens, scroll down to Draw or Hardware Acceleration. Find the option that is related to sensors or orientation (the names may differ on different versions of MIUI, sometimes called Force desktop mode or similar experimental features).

A more radical but effective method is to reset all settings to factory settings with data saved (not to be confused with a full reset). Go to Settings → Advanced Settings → Restore and Reset. Select Settings Reset (not All Data Reset) and this will return system settings, including sensor settings, to the original state.

Impact of MIUI Updates and Third Party Applications

Often, the problem with the autorotation on the Redmi Note 8 T occurs immediately after the operating system update. Xiaomi developers can change the algorithms of the sensors, which leads to conflicts with the old settings, in which case cleaning the cache of system applications helps.

Go to Settings → Apps → All apps. Search Google Play Services, Settings, and System Interface. Go to each of them and select Clear Cache (not data, but cache) to delete temporary files that may have been corrupted during the update.

You should also look at the screen control apps you have installed, and if you use smart wallpaper, ad blockers, or launchers (Nova Launcher, Go Launcher), they can take over the sensors, and try to temporarily disable them or remove them to see if you can get back to normal operation.

Version conflict is another common cause: If you have global firmware installed but you upgraded via recovery from the Chinese version, there may be hardware errors, and in such cases, it is recommended to completely flash the device through your computer using the Mi Flash Tool utility.

• 📉 Remove newly installed launchers and widgets.
• 🌐 Check the relevance of the version MIUI for your region.
• 🛡️ Turn off optimization. MIUI The Developer's Menu (Experimental).

⚠️ Note: When cleaning the data (not cache) of system applications, you can reset all your personalizations: wallpaper, icon location and Wi-Fi passwords. Be careful and choose "Clear cache».

Hardware causes and physical damage

There's no excluding a physical breakdown. The Xiaomi Redmi Note 8 T is a reliable smartphone, but falls, bumps, or moisture can knock out the accelerometer. This sensor is a chip on the board, and if you hit it hard, the contact can move away or the crystal can split.

If the phone is down or angled, the probability of damage to the internal components is high. In such cases, software methods (calibration, reset) will not work. The characteristic feature of hardware failure is the chaotic behavior of the screen: it spins on its own, twitches or does not respond to any action at all.

It's also worth checking if the proximity or illumination sensor is covered by a thick protective glass or case. Although these do not directly affect the accelerometer, some MIUI algorithms link the sensors into a single chain. Remove the case and wipe the top of the screen.

💡

Try gently tapping your finger on the back cover around the camera, which sometimes helps to restore contact with the outgoing accelerometer plume if the problem is mechanical displacement.

If you notice that the autorotation stopped working after the device hit the water, even in small quantities, immediately turn off the phone. The moisture could oxidize the contacts of the sensor, in which case only disassembly, cleaning the board with ultrasound and drying in the service center will help.

Radical measures: complete reset and reflashing

When all methods have been tried and the screen autorotation has not worked, the last resort is a full reset to the factory settings (Hard Reset), which will delete all data from internal memory, so be sure to back up important files.

Turn off the phone to perform the reset. Press up and on at the same time. Hold until the Mi logo appears, then release the on button, but keep the volume down until the Recovery menu appears. Select language (English), then "Wipe Data" → "Wipe All Data."

Once reset, the phone will go back out of the box, and if it's still out of the box, without apps and accounts installed, the autorotation doesn't work, that's a 100% indication of hardware failure, and you'll need to replace the accelerometer or the entire motherboard.

💡

If after a complete reset (Hard Reset) and check in safe mode autorotation does not work, the problem is hardware in nature and requires replacing the sensor in the service center.

In conclusion, the problem with the autorotation on the Redmi Note 8 T is solved 90% of the time by software. Start with simple steps: check the lock in the curtain and calibrate it in the engineering menu. Only if these actions do not lead to results, you should think about more complex manipulations or repairs.
