The automatic screen turn on the Xiaomi Redmi 8 is one of those features that you only notice when it stops working: you turn the phone into landscape orientation, and the picture stubbornly stays in portrait mode — or vice versa. 80% of the time, the problem is solved in 5 minutes, but sometimes you need a deep diagnosis. This article covers all possible causes, from a trivial sensor failure to hardware malfunctions that require repair.
We won't offer "reboot phone" as a panacea (although that works too). Instead, you'll get step-by-step instructions with screenshots, a firmware compatibility table, and proven sensor calibration methods that are rarely mentioned in standard guides. If you've tried turning auto-turn on/off in the notification curtain, read on. There's a solution.
In this article:
- 🔍 Diagnostics: how to determine whether a software failure or hardware failure
- ⚙️ Settings: hidden parameters MIUI, tyre-blocking
- 📱 Sensors: How to check and recalibrate a gyroscope/accelerometer
- 🛠️ Repair: When to carry your phone to the service (and how much it will cost)
1. Checking the basic settings: what you might have missed
Start with the obvious -- not the advice of 90 percent of the articles, not the auto-rotation button in the notification curtain, which everyone checks first. MIUI imposes on individual applications or modes.
Open the Settings. → Screen. → Autoturn and make sure that:
- 📱 Main switch switch switch on (slider must be blue)
- 🔄 Auto mode selected in the list of available orientations
- 🚫 No exceptions for the current application (check the list of "Exclusions for Applications")
Pay special attention to the application exceptions. Xiaomi can block autorotation for YouTube, Google Chrome or Gallery by default — even if the shared switch is on. Remove unnecessary apps from this list.
If the basic settings are fine, but the autorotation still doesn't work, move on to the sensor diagnostics, but first check the other thing: the power saving mode. MIUI When Super Power Saving is activated, all "unnecessary" sensors, including the gyroscope, are turned off. → Battery.
2.Diagnostics of sensors: how to understand what broke
The autoturn of the screen depends on two sensors:
- Accelerometer – determines the position of the phone in space
- Gyroscope – tracks corners of rotation
If one of them doesn't work properly, the screen won't turn, and you can check them without any special tools.
Method 1: Testing through the Engineering Menu
- Open the phone app and dial ##6484##
- Choose the Manual Test → Sensor Test
- Look at the Accelerometer and Gyroscope
When you turn the phone, the numbers should change smoothly.
- 🔢 Doesn't change at all. → The sensor is faulty or disabled at the system level
- 📉 Swapping. → calibration
- ❌ Showing a mistake → hardware-break
💡
If the engineering menu doesn't open, try the ##4636 code## → "Sensor information".
Method 2: Checking through applications
Install any of these apps from Google Play (they are free):
- 📊 Sensor Test (from Smart Tools)
- 🔧 Phone Tester (Sensors tab)
- 📱 CPU-Z (sensors)
In these apps, you'll see real-time graphs of sensors, and if the lines on the graph don't respond to the phone's turn or show random surges, the problem is with the sensors.
Calibration of sensors: step-by-step instruction
If the sensors are working but they're not showing the correct values, they need to be recalibrated, which resets the zero position of the sensors and restores the accuracy of the readings.
Method 1: Through the Engineering Menu
Call the number ##6484##|Choose the Manual Test → Sensor Test|Press Calibration for the accelerometer|Put your phone on a flat surface.|Wait until the phone is finished (don’t move the phone!)-->
Method 2: Through the application GPU Z (for advanced)
- Install. GPU Z from Google Play
- Open the Sensors tab
- Press Calibrate next to Accelerometer
- Follow the instructions on the screen (usually put your phone on the table and wait 10 seconds)
After calibration, restart your phone and check the autorotation. If the problem persists, proceed to reset the settings.
What if calibration doesn’t help?
4. Software failures: resetting settings and flashing
If the sensors are good but the autorotation doesn't work, it's a software problem. On Xiaomi Redmi 8, it could be related to:
- 🐛 Failure in MIUI (especially after updating)
- 📱 Application conflict (e.g. launchers or optimizers)
- 🔄 Incorrect Developer Settings
Step 1: Reset the screen settings
Go to Settings. → System system → Additionally. → Reset and select Reset screen settings, which will return to factory settings all the display settings, including autorotating.
Step 2: Disconnecting the Developer Mode
If you've previously enabled the developer mode, some of its options may block sensors.
- Go to Settings. → The phone.
- Press 7 times on the version MIUI, to disable the developer mode
- Reboot the phone.
Step 3: Fastboot Fastboot Fastboot Fastboot
If nothing has worked, the last resort is clean firmware installation. For Redmi 8, the official firmware is available on Xiaomi's website. Use the Mi Flash Tool for Fastboot.
⚠️ Warning: Flashing will delete all data from the phone. Pre-backup through Settings → Additionally. → Backup.
| MIUI version | Compatible with Redmi 8 | Famous auto-turning bugs |
|---|---|---|
| MIUI 12.5 | Yes. | Sometimes reset sensor settings after updating |
| MIUI 13 | Yes (Global version only) | Google Services Conflict Could Block Sensors |
| MIUI 14 | No (not officially supported) | Unremovable lags in the work of the gyroscope |
5. Hardware malfunctions: when you need to service
If all the software methods have been tried, but the auto-rotation still doesn't work, the problem is the hardware.
- 🔧 Sensor plume (passes away after falling or getting moisture)
- 📱 The sensors themselves (accelerometer or gyroscope)
- 🔋 Contacts on the motherboard (oxidation or breakage)
How to determine hardware breakdown:
- 🔍 Sensors do not respond at all (even in the engineering menu)
- 💧 The phone fell into the water or was heavily hit.
- 🔌 The autoturn stopped working suddenly, without updates or changes in settings.
Cost of repairs in service centers:
| Type of repair | Cost (₽) | Date(days) |
|---|---|---|
| Replacement of sensor plume | 1 200 — 1 800 | 1 |
| Replacement of the accelerometer/gyroscope | 2 500 — 3 500 | 2-3 |
| Cleaning contact fees | 800 — 1 500 | 1 |
⚠️ Warning: If the phone was in water, don't turn it on until you visit the service! Short circuit can damage the motherboard, and repairs will cost you a lot of money. 5-10 more expensively.
6. Alternative solutions: if the autoturn is not restored
If you can not fix the autorotation, but the screen is still working, you can use software bypasses:
1. Forced orientation through ADB
Connect your phone to your PC and execute the command:
adb shell settings put system accelerometer_rotation 1
adb shell settings put system user_rotation 0This will force the system-level autorotation, and if it doesn't work, the sensors are definitely faulty.
2. Applications for forced turnaround
Install from Google Play:
- 🔄 Rotation Control (Manual Orientation Control)
- 📱 Set Orientation (fixing any angle of rotation)
- 🎮 Ultimate Rotation Control (for games and video)
These apps do not restore sensors, but allow you to manually switch the orientation of the screen.
3. Use of gestures
V MIUI You can adjust the gesture to turn the screen:
- Go to Settings. → Additionally. → Gestures
- Turn on the screen with a gesture
- Now the screen will be triggered by double touch on the lower edge.
7. Frequent User Errors (and How to Avoid Them)
Many Redmi owners 8 They're making the auto-turn problem worse without knowing it.-5 mistake:
❌ Mistake 1: Using magnet covers
Magnetic cases (for example, to attach to a car) block the sensors. Remove the case and check the autorotation.
❌ Error 2: Disabling Google Services
Some SEOs suggest turning off Google Play Services to save power, causing sensors to fail.
- Settings → Applications → Application Management
- Find Google Play Services and enable auto-run
❌ Error 3: Update through OTA low-powered
If the phone was refreshed at less than 30% charge, the firmware could get crooked.
❌ Error 4: Install custom firmware without compatibility check
Firmware like LineageOS or Pixel Experience often doesn’t support Redmi 8 sensors 100%. 4PDA or XDA Developers.
❌ Error 5: Resetting settings without backup
When reset via Fastboot, the sensor calibration files are deleted. Always do a backup through TWRP Mi Cloud.
💡
If the autopivot stopped working after the phone fell, 90 percent of it is hardware. Don't waste your time on software methods, just get it to the service.
