Calibration of the gyroscope on Xiaomi Redmi Note 7: a complete guide with proven methods

Xiaomi Redmi Note 7 is still a popular smartphone due to its balanced performance and reliability, but over time, owners face problems in the operation of the gyroscope and accelerometer, failures manifest themselves in various ways, from incorrect screen rotation to “floating” images in games or applications of augmented reality, most often not hardware failures, but software errors that can be corrected by self-calibration.

In this article, we will discuss why the Redmi Note 7 gyroscope starts to “glue”, how to check its performance without special tools, and most importantly – three working methods of calibration (including hidden engineering menus).

Signs of a gyroscope malfunction on the Redmi Note 7

The gyroscope and accelerometer in the Redmi Note 7 are responsible for determining the position of the device in space, and their failures are often confused with problems with display or firmware, but there are characteristic symptoms:

• 🔄 The screen will spontaneously flip or get stuck in portrait/album mode, even if the autorotation is turned off.
• 🎮 In games (e.g., PUBG Mobile or Free Fire), the character moves in jerks and the aiming moves away.
• 📱 Applications with AR (e.g., Google Measure or Pokémon GO) give an error called “It is impossible to determine the position of the device.”
• 📊 In sensor tests (via EngineerMode or CPU-Z), the values of the gyroscope "hang" or show zeros.
• 🔧 After a fall or impact, the smartphone stopped responding to tilts, although the rest of the features work.

If you see any of these signs, the gyroscope is 80 percent likely to fail, but before you calibrate, you need to rule out other causes.

⚠️ Warning: Check to see if Do Not Disturb or Charge Saving mode is on, which can block sensors, and make sure that the smartphone doesn't have magnetic covers or metal accessories that distort the compass readings (it's connected to the hardware-level gyroscope).

For accurate diagnosis, use the Sensor Test app (available on Google Play), which shows data from all sensors in real time, and if the Gyroscope values do not change when the phone is rotating or if it shows random jumps, you need calibration.

Causes of gyroscope failures: software vs. hardware

On the Redmi Note 7, gyro problems fall into two categories, and let's look at them in the table.

On the Redmi Note 7, the gyroscope and accelerometer are combined in one chip (InvenSense ICM-20602), so when hardware fails, both sensors usually fail at the same time. If the calibration does not help, and the tests show zero values, this is a sure sign of physical damage.

Programmatic failures often occur after:

• 📱 Updates MIUI to 12.5+ (probable bugs with sensors in firmware for Redmi Note 7).
• 🔄 Install custom firmware (e.g. LineageOS or Pixel Experience).
• 🛠️ Use applications to overclock the processor or modify the kernel (e.g., Kernel Adiutor).

Calibration Preparation: What to Do Before Starting

Before you start calibrating, follow a few mandatory steps to avoid additional problems:

Backup important data (settings → Additional → Backup)

Charge your smartphone by at least 50% (to avoid turning off during the process)

Remove the cover and metal accessories (bracelets, rings)

Close all applications that use sensors (games, navigators, fitness trackers)

Shut down. VPN Firewalls (they can block access to the engineering menu)-->

If you are planning to use the engineering menu (method 2 or 3 from this article), remember:

• 🔐 The engineering menu codes (##6484### or #4636###) don't work on all firmware. If the code doesn't work, try an alternative way to log in via the MTK Engineering Mode app (for MediaTek processors).
• 📵 Do not interrupt the calibration process, which can cause sensors to fail. If the phone freezes, wait 2-3 minutes or reboot it forcefully (press Power + Volume up for 10 seconds).

⚠️ Warning: Some firmware MIUI has the engineering menu locked. If nothing happens after you enter the code, check if you have Settings disabled → Special Features → Engineer Menu (if you have one).

Also prepare a flat surface (such as a table) for calibration. The gyroscope is sensitive to vibrations, so perform the procedure in a quiet place, away from working household appliances (washing machine, air conditioner).

Method 1: Calibration of the gyroscope through standard MIUI settings

The easiest way, which works 60% of the time, is for users who have gyro failures after updating or installing new apps.

Instructions:

1. Open the Settings → Screen.
2. Find the Autoturn screen and turn it on (if it is turned off).
3. Return to the main settings menu and go to About Phone → All settings (tap 5-7 times on the MIUI version to unlock the developer mode).
4. Go back to Settings → More → For developers.
5. Find the Sensor Calibration option (or Gyro Calibration) and tap it.
6. Follow the instructions on the screen: Place the phone on a flat surface, then slowly rotate it along all axes (as shown in the animation).

If the sensor calibration item is not in the developer menu, try an alternative path:

1. Install the Accelerometer Calibration app from Google Play.
2. Run it and press Calibrate.
3. Place the phone up on the table and wait for the process to complete (usually 10-20 seconds).

💡

If the gyroscope still doesn’t work properly after calibrating, try rolling back the settings to factory settings. Go to Settings → About Phone → Reset and select Sensor Reset (not to be confused with a full reset!).

This method helps with minor software failures, but if the problem is deeper (for example, after a failed update), move on to the next method.

Method 2: Calibration through the engineering menu (for power users)

The Engineering Mode provides access to low-level sensor settings, a method that is more effective than standard calibration, but requires caution that improper actions can cause a system to crash.

Step-by-step:

1. Open the Phone app and enter the code: ##6484## If the code doesn't work, try the alternative: ##4636###
2. In the menu that opens, select Hardware Testing → Sensor.
3. Find the Gyroscope Sensor (gyroscope) in the list and tap it.
4. Press Calibration, and the system will suggest putting the phone on a flat surface.
5. After calibration is complete, check the sensor values – they should change smoothly as the device rotates.

If there is no calibration option in the engineering menu, try resetting the sensor data:

1. In the same Sensor menu, find Clear Data.
2. Confirm the action and restart the phone.

⚠️ Warning: In the engineering menu, do not change other parameters (e.g., Accelerometer Offset or Magnetic Field) unless you know what they are, and incorrect values can completely disable the sensors.

For Qualcomm Snapdragon 660 processors (which are in the Redmi Note 7), a hidden sensor test via code is also available:

##284##

It can be used to check the performance of the gyroscope in real time.

Method 3: Manual calibration via ADB (for advanced users)

If standard methods didn't work, and the gyro still gives out incorrect data, you can try low-level calibration using the ADB (Android Debug Bridge), which requires connecting the phone to a computer and basic command line knowledge.

What you need:

• 🖥️ A computer with installed Xiaomi drivers and ADB (You can download from the official website of Android Developers).
• 📱 Enables Debugging Mode on USB on your phone (Settings → Developer → Debugging on USB).
• 🔌 USB-cable (preferably original).

Instructions:

1. Connect the Redmi Note 7 to your computer and open the command line (Win + R → enter cmd).
2. Check the connection of the device by command: Adb devices should appear serial number of your phone.
3. Enter the command to reset the gyroscope calibration: adb shell settings put global gyro_calibration 0
4. Reboot your phone: adb reboot
5. Once enabled, reconnect to ADB and calibrate: adb shell am start -a android.intent.action.CALIBRATE_GYRO

If the command fails, try an alternative method using sensor_service:

1. Execution: adb shell service call sensor_service 1
2. Then, adb shell service call sensor_service 2

⚠️ Warning: The commands ADB may vary depending on the version MIUI. If after you type in the command, the phone restarts to bootloop, reset via fastboot: fastboot erase cache.

This is the most complex, but also the most effective, and it resets calibration data at the system level, and if it didn't work, it's probably a hardware problem.

💡

ADB- calibration is only suitable for advanced users. If you are not sure about your actions, you should contact the service center or use the methods 1-2.

What if calibration doesn’t help?

If none of the methods solves the problem, the reasons may be as follows:

• 🛠️ Hardware failure – the gyroscope is physically damaged (chip replacement is required).
• 📱 Firmware problem: MIUI has bugs that affect sensor performance (especially in versions 12.5.1.0–12.5.3.0).
• 🔋 Motherboard malfunction – for example, sensor contacts detached after falling.
• 🦠 Virus or malware – Some optimizers (e.g. Clean Master) block access to sensors.

Actions depending on the cause:

If you suspect a hardware breakdown, check:

• 🔍 Are other sensors working (accelerometer, compass, proximity sensor) and if not, the motherboard is the problem.
• 📅 When the problem occurred, if it falls or gets moisture, it's likely to need repairs.
• 🔧 Is there any autopsy marks on the phone (e.g., unpatched stickers on the screws) that may indicate a previous unqualified repair.

To diagnose the service, tell the wizard that you need to check the InvenSense ICM-20602 chip (this is the model of the gyroscope / accelerometer in Redmi Note 7). Replacing the sensor takes 1-2 hours and is cheaper than replacing the entire board.
