Modern smartphones, including the Xiaomi Redmi 10S, have a built-in digital compass, a useful tool for terrain orientation, hiking navigation, or even everyday tasks. However, many users do not know that this sensor requires proper tuning and periodic calibration to show accurate data. Unlike a classic magnetic compass, a smartphone counterpart depends on the magnetometer, gyroscope and accelerometer, which means that its accuracy can be reduced due to interference or failure.
In this article, we will discuss how to activate a compass on the Redmi 10S, check its performance, calibrate it for maximum accuracy and use it in popular applications. You will also learn why a compass can lie, how to avoid typical errors, and what alternative ways of orientation exist.
Where is the compass on Xiaomi Redmi 10S and how to turn it on
On Redmi 10S, the compass is built into the Compass system application, which is often hidden in the Tools folder or on the second menu screen. If the icon is not on the home screen, follow the following steps:
- 🔍 Open the Settings. → Annexes → Application management.
- 📱 Type "Compass" (or "Compass" for English firmware).
- 📌 If the application is disabled, click Enable.
- 📲 For quick access, add a shortcut to the home screen: hold the app icon and drag it.
If the system compass is not available (for example, after resetting or on custom firmware), it can be installed from Google Play. Recommended alternatives: Compass Galaxy or Digital Compass - they support additional features, such as saving coordinates or working offline.
How to check if the compass works on Redmi 10S
Before you calibrate the sensor, make sure it's functioning correctly.
- Open the Compass app and put your phone on a flat surface.
- Turn the device in a circle - the arrow should smoothly follow the movement.
- Compare the readings with a physical compass or Google Maps service (enable the Compass in the map settings).
If the arrow twitches, freezes, or shows the wrong direction, the problem may be:
- 🧲 External magnetic interference (metallic objects, speakers, magnet covers).
- 📱 Uncalibrated sensor (manual adjustment required).
- 🔧 Software failure (will help reboot or reset sensor settings).
💡
To eliminate interference, remove the case with a magnetic fastening and move away from metal objects (keys, knives, columns) by 1-2 meters.
Step-by-step calibration of the compass on Xiaomi Redmi 10S
Calibration is used to reset the sensor errors and synchronize it with the real magnetic field. On Redmi 10S, this is done through the system menu or third-party applications. Let's look at both.
Method 1: Through phone settings
This method works on standard MIUI firmware:
- Go to Settings → About the phone → All the characteristics.
- Find Sensors and select Sensor Test (or Sensor Test).
- Scroll to the Compass and press Calibration.
- Follow the instructions on the screen: rotate the phone in the shape of eight 3-4 times.
Method 2: Using GPS Status & Toolbox
If the system calibration is not available, use GPS Status & Toolbox:
Download the app from Google Play
Open the Compass tab
Press "Calibrate" (Calibrate)
Rotate the phone on all axes until the green tick appears-->
After calibration, check the accuracy: the direction north should match the physical compass or Google/Yandex maps with an error of no more than 5-10 °. If the difference is greater, repeat the procedure or check the phone for hardware damage.
What if calibration doesn’t help?
Causes of incorrect operation of the compass and how to eliminate them
Even after calibrating the compass on the Redmi 10S can fail, let's look at the typical problems and solutions:
| Problem. | Possible cause | Decision |
|---|---|---|
| The arrow twitches chaotically | Magnetic interference from cover or accessories | Remove the cover, move away from metal objects |
| The testimony "frozen" | Failure of the sensor or software | Restart your phone or reset sensor settings |
| Difference from real north >20° | Incorrect calibration or damage to the magnetometer | Repeat calibration or contact the service center |
| Compass is offline. | Application disabled or removed | Turn on in the settings or install an analog from Google Play |
⚠️ Note: If the compass stopped working after a phone drop or moisture hit, the problem may be hardware. In this case, calibration will not help - diagnostics are required at the Xiaomi service center.
How to use a Redmi 10S compass on hiking and everyday life
The digital compass is not only convenient for tourists, but also in urban settings. Here are some practical scenarios:
- 🗺️ Landscape orientation: Combine compass readings with topographic map (e.g. Locus Map or Osmand).
- 🚗 Parking in the sun: Remember the direction when parking to later find the car in the shadows.
- 🏠 Determination of cardinal points in the apartment: Useful for placing furniture on feng shui or installing an antenna.
- 🎯 Geocaching: In games like Pokémon GO Geocaching compass helps to determine coordinates more accurately.
On Redmi 10S, you can integrate your compass with Google Maps: turn on compass mode in the map settings (double tapping on the blue dot of your location), which will allow you to navigate even without the Internet if you download offline maps in advance.
Comparison of Redmi 10S Compass Accuracy with Other Devices
The compass's accuracy depends on the quality of the magnetometer and the data processing algorithms. The Redmi 10S uses an AK09918 sensor (or similar), which provides an error of ~3-5° under ideal conditions.
- 📱 Flagship smartphones (for example, Xiaomi 13 Pro): error 1-3°.
- 🧭 Mechanical compasses: error 1-2° (It doesn't depend on electronics).
- 🎯 Professional GPS-navigators: error <1° (For example, Garmin).
For most tasks, the Redmi 10S is accurate, but in extreme conditions (for example, in mountains or dense forests), it is better to have a spare mechanical compass. Also remember that near power lines or magnetic anomalies (for example, the Kursk magnetic anomaly), the readings of any electronic compass can be distorted.
💡
For maximum accuracy, combine compass data with GPS and visual landmarks (sun, stars, terrain).
Alternative Orientation Methods If the Compass Fails to Work
If the Redmi 10S compass fails, use alternative methods:
- GPS-Navigation: Apps like Google Maps or Maps.me show direction even without a compass (but require internet or offline maps).
- Sun and clock: In the northern hemisphere at noon, the sun is in the south. A clockwise hand pointed at the sun divides the angle with the number 1 in half - the bisectris will point south.

For reliability, install offline cards and the Offline Survival Manual app on your phone – it contains detailed instructions for orienteering without technique.
