Why you need a compass in a smartphone and how it works on Xiaomi
Todayβs Xiaomi smartphones are equipped with a magnetic field sensor that allows you to use the device as a full-fledged compass β from orientation to shooting video with the overlay of direction. But many users are not even aware of this feature or face problems with accuracy. In this article, we will learn how to properly configure and use a compass on Redmi, POCO or Mi-series, including shooting video with mapping of the worldβs sides.
The compass in the phone is powered by a magnetometer, a microchip that measures the strength of the Earth's magnetic field, but it can be distorted by metal objects, electronics, or even a magnetically-mounted case, and we'll show you how to minimize errors and achieve maximum accuracy, and where to find the hidden functions of the compass in MIUI firmware.
We'll focus on capturing compass overlay videos, which are useful for tourists, fishermen or content creators, and you'll learn which apps support this feature, how to customize the display and save the recording without artifacts, and at the end of this article, a selection of video instructions from official Xiaomi channels and enthusiasts.
Where to find a compass on Xiaomi: standard and hidden ways
In most models, the compass is built into the Compass app, but its location depends on the version of MIUI. On new devices (for example, Xiaomi 13 or Redmi Note 12), the icon can be hidden in the Tools folder or not at all in the menu.
- π Search by system: Swipe down the main screen and type "Compass" in the search bar. The system will show the application even if it does not appear in the menu.
- π± Tools folder: Some firmwares have a compass hidden with a flashlight, a voice recorder and a calculator. Check this folder on your desktop.
- βοΈ Settings β Appendices: Open Settings β Annexes β Manage applications and type "Compass" into the search. If the application is disabled, turn it on.
- π Google Maps: Turn on the compass in Google Maps (twice tap the location icon) β A northerly arrow will appear).
If the standard app is not available, it can be installed from Google Play. the official application from Xiaomi is called Mi Compass, but any high-rated analogue (for example, Compass Galaxy or Digital Compass) will do.
β οΈ Note: On budget models (e.g. Redmi) A1 or POCO C50) The magnetometer may be physically absent. Check the specifications of your model on the official Xiaomi website by model number (you can find it in Settings). β The phone).
Calibration of the compass: why the arrow lies and how to fix it
Even if the compass is showing direction, it can be inaccurate due to miscalibration or external interference.
- π§² Metal objects near the phone (keys, coins, magnet case).
- πΆ Electromagnetic fields from other devices (laptop, router, speakers).
- π Traffic in transport (especially in the subway or trains).
- π± Uncalibrated sensor after update MIUI.
To calibrate your compass on Xiaomi, follow the following steps:
- Open the Compass app.
- If the arrow twitches chaotically, a notification Requires calibration (in English firmware - Calibrate compass) will appear.
- Follow the hints on the screen: usually rotate the phone in space, describing it as an eight, or tilt it from different angles.
- After successful calibration, the arrow stabilizes and the accuracy increases to Β±2Β°.
If the automatic calibration doesnβt work, try manual resetting:
Settings β Applications β Application Management β Compass β Storage β Clear dataRemove metal objects within a radius of 1 meter |
Turn off Bluetooth and Wi-Fi|
Find an open space (better on the street)|
Hold the phone horizontally with your palm |
Recalibrate the calibration. 2-3 time-in-time-->
Shooting video with a compass on Xiaomi: step-by-step instructions
One of the most useful features of the compass on Xiaomi is the ability to superimpose the direction of the cardinal points directly on the video, which is indispensable for tourists, hunters or bloggers who film routes, but not all Xiaomi cameras support this feature out of the box.
Method 1: Built-in camera (for supported models)
- Open the standard Camera app.
- Switch to Video Mode.
- Touch the icons βοΈ (setting) β Additionally. β Show me a compass.
- A translucent scale will appear on the screen indicating north (N), south (S) and current azimuth.
- Start shooting - the direction will be recorded over the video.
Method 2: Third-party applications
If your model (POCO X3, Redmi 9, etc.) does not have an option built in, use:
- π₯ Open Camera (free, with compass overlay support and free of charge) GPS-coordinate).
- π§ Compass Camera (specialized application for shooting with a compass).
- πΊοΈ OSMAnd (for recording tracks with video binding).
Important: When shooting with a compass, turn off stabilization (if it is on), as it can distort the sensor readings, and make sure that the phone does not overheat, this increases the error of the magnetometer.

If the compass on the video is too small, zoom in on the font settings of the camera app. In Open Camera, this is done in Settings β Screen β Text Size
Table: Compass compatibility with Xiaomi models (2020β2026)
| Model | Presence of magnetometer | Built-in compass in the cell | Accuracy (inaccuracy) |
|---|---|---|---|
| Xiaomi 13/13 Pro | β Yes. | β Yes. MIUI 14) | Β±1β2Β° |
| Redmi Note 12 Pro+ | β Yes. | β No (third party software required) | Β±3Β° |
| POCO F5 | β Yes. | β Yes) | Β±2Β° |
| Redmi A2 | β No. | β No. | β |
| Xiaomi Mix Fold 3 | β Yes. | β Yes (with additional sensors) | Β± 0.5Β° (high accuracy) |
Important: On foldable models (for example, Mix Fold), the compass may show incorrect data when bending the screen - this is due to a change in the position of the magnetometer relative to the body.
Common Mistakes and How to Avoid Them
Even after calibrating the compass on Xiaomi, it may not work properly.
β οΈ Note: If after the update MIUI The compass stopped working, check if the sensor is turned off in Settings β Special facilities β Sensors. Sometimes resets reset and magnetometer resolutions.
- π Gun spins chaoticly: Problem is iron jamming. Get the phone off the metal, turn off the metal NFC and recalibrate.
- π The readings "float" when moving: The culprit is a gyroscope. Turn off the auto-turn screen in the notification curtain.
- π‘οΈ Compass warms and lags: CPU overheating affects sensors. close background apps and let phone cool.
- π« The compass app won't open: Permissions are likely lost. Go to Settings β Annexes β compass β Permits and enable access to Location and Sensors.
If nothing helps, try resetting the sensor settings:
Settings β About phone β All specs β Core β Sensors β ResetThis path may vary depending on the model, and some devices will need to enter the code ##4636## and select Sensor Test.

Combine compass data with GPS for maximum accuracy. In applications like Google Earth or OSMAnd, you can check the direction of satellites, which reduces the error to Β±0.5Β°.
