If you own a Xiaomi smartphone, you’ve probably noticed an app called Compass in the installed list, and many users mistakenly believe it’s useless or even delete it without realizing it’s hidden. In fact, it is not just a hand indicator of the cardinal directions, but a full-fledged navigation tool integrated into the ecosystem. MIUI.
In this article, we will analyze in detail what the Compass application is on Xiaomi, Redmi and other devices. POCO, How it works at a technical level, what features are hidden behind the minimalist interface, and why it is definitely not worth ignoring. Particular attention will be paid to typical problems (for example, when the compass shows the wrong direction due to inconsistency of sensors) and ways to eliminate them without contacting the service center.
What is the Compass app on Xiaomi and why you need it
Compass is a standard system software preinstalled on all Xiaomi smartphones running MIUI. It uses the device’s built-in sensors — a magnetometer, accelerometer and gyroscope — to determine the phone’s orientation in space and point the world. Unlike third-party navigation applications (such as Google Maps or Yandex.Maps), it does not require an Internet connection and works completely autonomously.
The main tasks for which the compass is designed:
- 🧭 Orientation in the area without GPS (useful in the forest, mountains or in conditions of poor signal).
- 📱 Calibration of sensors for other applications (e.g. augmented reality games or fitness trackers).
- 🔧 Diagnostics of hardware problems – if the compass is not working, it may indicate a malfunction of the magnetometer.
- 🌍 Integration with maps - some versions MIUI Allows you to overlay compass data on Google Maps.
It is important to understand that the accuracy of the compass depends on the calibration of the sensors and the absence of interference. For example, near metal objects or electromagnetic fields (for example, in the subway), the readings can be distorted.+) It uses an improved interference filtering algorithm, but even these are not immune to failures.
How to Open and Use the Compass App on Xiaomi
Find the Compass application in several ways:
- Through the app menu – look for an icon with a hand compass (usually blue or white).
- Through a search by system: swipe down the main screen and type in the search bar "Compass".
- Through Settings: Go to Settings → Annexes → App management and find Compass in the list.
The interface of the application is minimalist:
- 📌 In the center of the screen is a hand compass indicating the cardinal directions (North is indicated in red).
- 📱 Below is the angle of deviation in degrees (from 0)° 360°).
- 🔄 Calibration button (if available in your version) MIUI).
To use the compass:
- Hold your phone horizontally (parallel to the ground) for accurate readings.
- Turn the device around its axis - the arrow should smoothly follow the movement.
- To calibrate (if the arrow twitches), move the phone in the form of eight or use a special option in the menu.
☑️ Preparation for the use of the compass
In some models (for example, POCO F5 Xiaomi 13T) The compass is integrated into the Security app. To find it, open Security. → Tools → compass.
Technical features: how does the compass on Xiaomi smartphones
The Compass app relies on data from three key sensors:
- Magnetometer – Measures the strength of the Earth’s magnetic field and determines the direction to the north.
- Accelerometer - fixes acceleration and helps to adjust readings when tilting the phone.
- Gyroscope - tracks the angular speed of the device for smooth display of the arrow.
The algorithm of the work can be described as follows:
- Sensors read data about the position of the phone in space.
- The program compares the readings of the magnetometer with a map of the Earth's magnetic fields.
- Taking into account the amendments from the accelerometer and gyroscope, the final direction is derived.
Interesting fact: Xiaomi models with Snapdragon 8 Gen 2 chipset (for example, Xiaomi 13 Ultra) use an improved magnetometer from Bosch (model) BMM150), It's a very accurate way of determining azimuth, even in urban jamming, in low-end devices like Redmi. 12C) It may be less sensitive sensor, which affects accuracy.
| Xiaomi model | Type of magnetometer | Accuracy (inaccuracy) | Support for calibration |
|---|---|---|---|
| Xiaomi 14 Pro | AK09918C (AKM) | ±1° | Automatic + manual |
| POCO X5 Pro | MMIC224x (MemSense) | ±3° | Only automatic. |
| Redmi Note 12 | BMM150 (Bosch) | ±2° | Manual (through "eight") |
| Xiaomi 12T | YAS539 (Yamaha) | ±2.5° | Automatic. |
If the compass shows incorrect data, the problem may lie in:
- 🔋 Discharged battery – at low charge, sensors work unstable.
- 📱 Software failure – helps reboot or reset application settings.
- 🧲 External magnetic fields – remove the phone from speakers, chargers, or metal objects.
💡
If the compass lies after calibration, try turning off the Charge Saving function in the battery settings – it can limit the operation of the sensors.
Why Xiaomi Compasses May Not Work and How to Fix Them
Compass problems fall into two categories: software (solved by settings) and hardware (required repairs).
1. The compass arrow twitches or rotates chaotically
This is a sign of sensor inconsistency.
- Calibrate: Open the compass and rotate the phone in the air, describing the eight (or follow the hints on the screen).
- Check if magnetic interference interferes (such as a magnet case or wireless charging).
2.The compass shows the wrong direction
Possible causes:
- 📍 Incorrect geolocation – the compass can get lost if the phone settings indicate the wrong region. → Additionally. → Region.
- 🔄 Failure in sensor data – reset the Compass app settings in Settings → Annexes → compass → Warehouse → Drop it.
3.The Compass app is not on the menu
In some cases, the scalp (especially on the POCO Or Redmi for the European market, the compass can be hidden to get it back:
- Install a launcher from Xiaomi (for example, POCO Launcher can hide system applications).
- Enable the display of hidden applications in the launcher settings.
- If the compass is removed, download it. APK-file from an official source (e.g. APKCombo) and install manually.
What if calibration doesn’t help?
⚠️ Note: Don’t use the “compass enhancement” apps from Google Play — many of them contain malicious code or simply duplicate the functionality of a standard compass. Xiaomi’s official software is already optimized for your model.
Hidden compass functions on Xiaomi: what does the application besides specifying the cardinal points
Many users do not know that the compass in the MIUI It can do more than just point the direction. Here are some useful tips:
1. Integration with Google Maps
On some models (such as Xiaomi 13 or Mix Fold 3), you can overlay compass data on Google Maps:
- Open Google Maps and turn on compass mode (double tap on the location icon).
- The arrow on the map will be synchronized with the readings of the system compass.
2. Definition of azimuth for trekking
If you're a tourist, the compass can show an azimuth (the angle between the north and the chosen site).
- Point the phone camera at a target (for example, the top of a mountain).
- Remember the value in degrees at the bottom of the screen — that's the azimuth.
3. Checking the operation of sensors for AR-game
Augmented reality games (for example, Pokémon GO Harry Potter: Wizards Unite requires a precise gyroscope and compass, and if the characters in the game don't turn the way you do, check the compass first:
- Open the Compass app and turn the phone.
- If the arrow moves smoothly, the problem is in the game settings.
- If you're twitching, calibrate the sensors.
4. Quick access via widget
To avoid looking for a compass in the menu, add it to the main screen:
- Hold the empty space on the desktop.
- Select "Widgets» → find Compass.
- Drag the widget onto the screen.
💡
The compass on Xiaomi can serve not only as a navigation tool, but also as a sensor diagnostic tool. If it does not work correctly, there is a high probability that there will be problems in other applications using a gyroscope or magnetometer (for example, in the camera or games).
How to improve the accuracy of the compass on Xiaomi: tips and life hacks
If you are not satisfied with the accuracy of a standard compass, try these methods:
1. Manual calibration through the engineering menu
For advanced users:
- Enter the dialer code ##6484## (on some models #4636##).
- Select Sensor Test» → «Magnetic Field».
- Follow the instructions on the screen for accurate calibration.
⚠️ Note: Not all Xiaomi models support this code. On new devices (e.g. Xiaomi 14), the engineering menu may be blocked.
2.Use of third-party testing applications
Utilities like Sensor Box for Android or Physics Toolbox Sensor Suite allow you to:
- 📊 View raw data from the magnetometer.
