Setting up a gyroscope on Xiaomi Redmi 8: calibration, checking and troubleshooting

Xiaomi Redmi 8 is a budget smartphone with a good set of sensors, including a gyroscope, which is responsible for determining the spatial position of the device. However, many users face problems: games with support for a gyroscope (for example, games with a gyroscope, PUBG Mobile or Call of Duty: Mobile are not working properly, the sensor floats or does not respond to movement, and in most cases, the fault is downed settings, lack of calibration or software failures.

In this article, you will find step-by-step instructions for setting up a gyroscope on Redmi 8, including sensor health checks, manual calibration, and ways to fix typical problems. VR-What to do if the sensor stops functioning after the update MIUI. All methods are tested on current versions of firmware and do not require root rights.

What is a gyroscope in a smartphone and why you need it

A gyroscope is an angular velocity sensor that measures the rotation of a device around three axes: X (roll), Y (tangage) and Z ( yaw). Unlike an accelerometer that captures linear accelerations, a gyroscope more accurately tracks turns and inclinations. Xiaomi Redmi 8 uses a new model to track the curves and inclinations. MEMS-gyroscope (microelectromechanical system) integrated into InvenSense chip ICM-42688.

The main functions of the gyroscope in the smartphone:

• 🎮 Control in games: Screen turns for aiming (for example, in shooters) or transport control (racing simulators).
• 🕶️ VR/AR-Apps: Head tracking in virtual reality or augmented reality glasses (e.g. Google Cardboard).
• 📱 Automatic Screen Rotation: Working with an accelerometer to Change Display Orientation.
• 🧭 Navigation: Improved accuracy of positioning in space (e.g. in Google Maps on foot).

Redmi 8 gyroscope is also used for gestures MIUI, For example, for the function "Raise to unlock" or "Rotate to turn on the flashlight." If the sensor is not working correctly, these functions may spontaneously or not respond at all.

How to check the work of the gyroscope on Xiaomi Redmi 8

Before you set up the gyro, make sure it works at all. You can use it as built-in tools. MIUI, So, third-party apps. Here are three reliable diagnostic tools.

Method 1: Integrated sensor test in MIUI

The manufacturer has hidden direct access to the sensor test, but it can be run through the engineering menu:

1. Open the phone app and enter the combination: ##6484###
2. Select the Manual Test item → Sensor → Gyroscope.
3. Look at the graphs on the X, Y, Z axes, and when you rotate your phone, the lines should change smoothly, and if the graphs are frozen or you see chaotic jumps, the sensor is broken.

Method 2: Appendix CPU-Z

Utility. CPU-Z (Available on Google Play, displays the technical data of the smartphone, including sensor information:

1. Install and open the CPU-Z.
2. Go to the Sensors tab.
3. Find the Gyroscope unit. As the device rotates, the values should change synchronously.

Method 3: Specialized Utilities

For deep diagnostics, applications like Sensor Box for Android or AndroSensor can visualize the gyroscope data in real time:

• 📊 Sensor Box: Shows 3D-Smartphone model and its current position in space.
• 🔄 AndroSensor: displays graphs and numerical values on all axes, and also allows you to write a data log.

💡

If the gyro doesn't respond in any of the tests, try restarting your smartphone, and sometimes the sensor freezes after long-term use of resource-intensive applications.

If the gyroscope doesn’t work in all tests, the problem may be:

• 🔧 Software failure (following settings, application conflict).
• 📱 Hardware failure (damage to sensor or plume).
• 🔄 Outdated firmware (bugs in) MIUI for Redmi 8).

Calibration of the gyroscope on Xiaomi Redmi 8: step-by-step instructions

Calibration is the process of tuning a gyroscope to accurately determine the "zero" position (when the device lies on a flat surface). On Redmi 8, calibration is reset after falls, system updates or sensor failures. Here's how to do it.

Method 1: Automatic calibration through MIUI

System system MIUI It has a built-in calibration mechanism that starts under certain conditions:

Place your phone on a flat horizontal surface (such as a table)

Make sure there is no magnetic interference nearby (columns, headphones, magnet covers)

Do not touch the device for 10-15 seconds.

Connect the charger (optional but recommended)

-->

1. Go to Settings. → The phone. → Version. MIUI and tap 7 times on the line Version MIUI, activate the developer mode.
2. Back to Settings → Additionally. → For developers.
3. Find the Sensor Calibration option (or Sensor Reset in newer versions) MIUI) and choose her.
4. Follow the instructions on the screen: You usually need to put your phone on the table and wait 30 to 60 seconds.

Method 2: Manual calibration through the engineering menu

If the automatic calibration does not help, use the engineering menu:

1. Enter the phone code in the app: ##6484##
2. Choose the Manual Test → Sensor → Gyroscope.
3. Press Calibration (if the option is available).
4. Place your phone on a flat surface and wait until the process is complete (usually takes 1-2 minutes).

Method 3: Calibration through ADB (for power users)

If the standard methods did not work, you can reset the gyroscope settings via Android Debug Bridge (ADB):

1. Install. ADB-Drivers on PC and enable Debugging by USB in the developer settings on the phone.
2. Connect Redmi 8 to your computer and open the command line.
3. Enter the command: adb shell settings put global sensor_calibration 1
4. Reset the device.

💡

After calibration, check the gyroscope in the game or test app. If the sensor is still floating, the problem may be the firmware or hardware.

Setting up a gyroscope for games (PUBG, COD, Free Fire and others.)

Many mobile games support gyro control, but for a comfortable game on Redmi 8 requires additional adjustment.

General recommendations for setting up

• 🎯 Sensitivity: A gyroscope is usually set to 10-20% lower than a sensor (e.g., if the sensor is 80 percent, the gyroscope is set to 60–70 percent%).
• 🔄 Mode: Most games have Always On (gyroscope works constantly) and Scope Only (on when aiming.
• 📱 Screen orientation: in the game settings, turn off Autorotation and fix orientation in landscape mode.

Optimal settings for PUBG Mobile

V PUBG Mobile gyroscope is configured in the Settings section → Mainstream → Sensitivity:

Setting up for Call of Duty: Mobile

V COD Mobile Way to Settings: Settings → Management → gyroscope:

• 🎛️ Sensitivity: 40-60% (to start with).
• 🔫 Regime: ADS Only (similar to Scope Only) PUBG).
• 🔄 Calibration in the game: in the gyroscope menu there is a Recalibrate button - use it if the control has left".

Typical gyroscope problems on Xiaomi Redmi 8 and their solutions

Even after calibration, the Redmi 8 gyro can be unstable, and below are the most common problems and ways to fix them.

Problem 1: The gyroscope is floating or spinning spontaneously

If the sensor shows chaotic movements without your intervention, the reasons may be:

• 🧲 Magnetic interference: magnet cases, wireless charging or headphones near your phone.
• 📱 Failure in MIUI: Flying settings after update.
• 🔋 Low battery power: at levels below 15%, the system limits sensor performance.

Decision:

1. Remove all magnetic devices near your phone.
2. Calibrate through the engineering menu (see section above).
3. Reset sensor settings: Settings → Annexes → Application management → Three points. → Resetting application settings.

Problem 2: The gyro doesn’t work in games, but it does in tests

If the sensor is functional, but the games do not see it, the resolution settings or conflict with other applications are to blame.

Decision:

• 🔒 Permissions: Check that the game has access to sensors in Settings → Annexes → [Game] → Permits.
• 📱 Performance mode: turn on for the game in Settings → Battery → Choice of performance mode.
• 🔄 Resetting the game's cache: Settings → Annexes → [Game] → Clear the cache.

Problem 3: The gyroscope stopped working after the update MIUI

Firmware updates sometimes reset sensor drivers.

2. If you cannot reset, reset your settings: Settings → Additionally. → Recovery and discharge → Resetting settings (data not deleted).
3. Install the custom core (requires unlocking the bootloader and root rights).

💡

If the gyro stopped working after the phone fell, the sensor or plume would probably be damaged, and only repairs at the service center would help.

Additional Tips for Optimizing a Gyroscope

To make the Redmi 8 gyroscope work as accurately as possible, follow these guidelines:

1. Disable unnecessary sensors

Some applications are constantly questioning the accelerometer, compass or proximity sensor, which puts a strain on the system and can interfere with the gyroscope.

1. Go to Settings. → Annexes → Permits → Sensors.
2. Limit sensor access for unnecessary applications (such as social media or launchers).

2.Use the game mode MIUI

MIUI Has a built-in game mode that optimizes performance for games:

• 🎮 Activation: Swipe down the notification panel and tap the Game icon (will appear when you start a supported game).
• ⚡ Settings: in game mode, select Performance and enable the option to Improve tactile return (this indirectly affects the responsiveness of the gyroscope).

3. Check the temperature of the processor

The Snapdragon 439 chipset in Redmi 8 is prone to overheating, causing trottling and slowing down the sensors.

• 🌡️ Install the app CPU Monitor for temperature monitoring.
• 🔋 Do not play when charging - it increases heat.
• 🧊 Use a cooling case or stand with a fan.

4. Update sensor drivers manually

If the gyro is unstable, try updating its drivers via Fastboot:

1. Download the latest version MIUI Fastboot ROM Redmi 8 from the official Xiaomi website.
2. Unpack the archive and find the sensors.*.img file (usually in the image folder).
3. Fastboot flash sensors: Quickboot flash sensors sensors.img

💡

If you play with a gyro often, turn off the autorotation of the screen in the Android settings. This will reduce the load on the sensors and improve responsiveness.

What to do if the gyroscope on Xiaomi Redmi 8 does not work at all

If none of these methods worked, and the gyro still doesn't respond, the reasons may be hardware.

1. Check the sensor plume

The Redmi 8 gyroscope is placed on a separate board, along with an accelerometer and a compass, and if the phone fell or was vibrating, the plume connecting the board to the motherboard could be damaged.

Signs of plume damage:

• 🔌 The gyroscope and accelerometer do not work at the same time.
• 📱 The phone does not respond to autorotation of the screen.
• 🔍 In the engineering menu, sensors are not defined at all.

Solution: dismantling and replacing the plume in the service center, the average cost of repair is 1,500-2,500 rubles.

2. Refuse the smartphone

If the problem occurred after the update, the sensor firmware may have crashed. Try reflashing the phone through the Mi Flash Tool:

1. Download Fastboot ROM Redmi 8 (Global or Eea Version).
2. Install the Mi Flash Tool on your PC.
3. Connect your phone in Fastboot mode (clip Volume Down + Power when the device is off).
4. In Mi Flash Tool, select Clean All mode and click ROM.

3. Contact the service center

If the gyroscope does not work after all the manipulations, most likely, the sensor itself failed. In this case, the chip is required to be replaced, which is possible only in the conditions of the service center. The cost of replacing the gyroscope with Xiaomi Redmi 8 in official Xiaomi services is about 3000-4000 rubles (2026).
