Modern Xiaomi and Redmi smartphones are equipped with high-precision navigation modules, but often users are faced with a situation where maps can not determine the location, this is due to software failures or incorrect privacy settings in the MIUI shell.
In this article, we will explore in detail not only the basic activation methods, but also the hidden settings that affect positioning accuracy, how to make a device see more satellites and why a standard switch switch switch switch on is sometimes not enough for stable operation.
Understanding these processes will help avoid common mistakes when a navigator jumps on a map or searches for a signal in dense urban areas.
Basic activation through the control panel
The fastest way to start the navigation module is to use a notification curtain. Swipe your finger from the top edge of the screen down to unfold the Quick Settings panel. Among the many icons, you need to find an icon labeled “Location” or “Geodata”.
If the icon is inactive (gray), just press it once, it should be illuminated in blue or green, which signals the start of the module. In some versions of the MIUI shell, it may take a long press to go to the expanded settings menu.
Importantly, once enabled, the system can request confirmation of geodata usage policies, a standard procedure for complying with Android’s privacy policy.
- 📍 Swipe from top to bottom to open the control center.
- 📍 Find the Location icon (often looks like a card pin).
- 📍 Click to activate, make sure to change the color of the indicator.
⚠️ Warning: If the icon in the curtain immediately goes out or turns gray after turning on, check the battery level.In energy austerity mode, the system can force the power-intensive modules to be turned off.
Once activated successfully, you should check the service immediately. Open any map application, such as Yandex.Maps or Google Maps, and see if the current point has been determined. If the cursor is displayed correctly, the basic setting is complete.
Setting parameters in the system menu
To get a deeper setup, go to the main menu of the device, find the Settings icon and scroll through the list to the “Additional Settings” or “Applications” section, and we’re interested in “Privacy” or “Security and Location”.
The main mode switch is available inside the Location menu, and you can choose the method of determining the coordinates, and for maximum accuracy in urban and built-up conditions, you should choose GPS, Wi-Fi and mobile mode.
Using only GPS satellites can take a long time at a cold start, and using only networks gives a large margin of error. The combined method allows the Xiaomi device to quickly lock in position using cell tower data for initial positioning.
☑️ Checking location settings
Also hidden in this section is the important feature, "Improving Accuracy," which allows the phone to use motion sensors and Wi-Fi data from the networks around it to refine coordinates, even if you're not connected to a particular access point.
Managing permissions for applications
It is often the case that GPS is globally enabled, but a specific application (such as a taxi or navigator) does not see the location, which means that the program does not have the appropriate permissions on the Android system.
Go to Settings, select Apps, and find the program you want (like 2GIS or Uber) in the list. Click App Permissions and make sure that access to the location is set to “Allow Always” or “Allow Only When Used.”
Newer versions of MIUI have added the “Exact Location” feature, which, if turned off, will only show you a sample area of your location, making it impossible to call a door-to-door taxi.
- 🔒 Open the settings of a particular application.
- 🔒 Go to the section "Permissions».
- 🔒 Select “Location” and set a priority.
⚠️ Warning: Do not give permission to access the geo-location suspicious applications such as flashlights or simple calculators.
Why does the app ask for access all the time?
If you changed the settings, but the app still says "No signal," try closing the program completely through Task Manager and running it again. The old coordinate cache could conflict with the new data.
Calibration of compass and elimination of errors
Sometimes the directional arrow in the navigator turns or shows the wrong direction of movement, this requires calibrating the magnetic sensor and the accelerometer. On Redmi smartphones, this procedure can be performed through an engineering menu or special utilities.
You can use the eight method for manual calibration, and you can take the phone in your hand and draw the number eight in different planes in the air. 10-15 This helps the system redefinite the magnetic field vectors.
A more professional method is to use a hidden engineering menu, type ##6484## in the ringer (code may vary depending on model and region). In the CIT menu that opens, select Compass or Sensor and follow the instructions on the screen.
#6484## - Entering the engineering test menuIf the software calibration doesn't work, maybe there's a strong magnetic holder or a magnetic clasp on the back of the device, and these accessories can distort the sensors.
💡
Use the Google Maps app for quick calibration. Click on the blue dot of your location and select "Calibrate." Follow the instructions for drawing the eight.
Use of A-GPS auxiliary data
A-GPS (Assisted GPS) technology makes satellite search much faster, and instead of scanning the sky for signals for long periods, the phone downloads the satellite's current almanacs over the Internet, allowing it to pinpoint the coordinates in seconds, even in difficult conditions.
On Xiaomi devices, this feature is usually enabled by default, but it is worth checking its status. In some software builds, you may need to reset the A-GPS cache if the navigation started to work incorrectly after the system update.
Third-party utilities such as GPS Status & Toolbox can be used to reset and update data. From the app menu, select “Manage A-GPS Status” and click “Reset” and then “Download”.
| Parameter | Description | Impact on work |
|---|---|---|
| Cold start | First launch without data | Long wait (up to 2 minutes) |
| Warm start | The data in the cache is relevant | Instant determination (5-10 seconds) |
| A-GPS data | Almanacs via the network | Accelerates a cold start at times |
| EPO data | Expanded ephemerides | Increases accuracy in the forest/city |
Regular updates are especially important if you travel long distances, and satellite almanacs tend to become obsolete, and the phone will look for a signal longer using old tables.
Problems with indoor definition and their solution
GPS satellite signals are very weak and don't penetrate concrete walls and metal structures very well, so if you're inside a building, the phone can switch to Wi-Fi routers, which gives you a big margin of error.
To improve indoor reception, try to approach windows. Glass transmits radio waves much better than concrete or brick, and it is also worth removing a thick protective case, especially if it contains metal elements or magnets.
In some cases, it helps to turn on the flight mode for 5-10 seconds and then turn off, which restarts all radio modules, including GPS, and causes the device to re-register and rescan the air.
- 🏢 Come closer to the window opening.
- 🏢 Remove the case with metal inserts.
- 🏢 Restart the communication module via air mode.
⚠️ Warning: In basements, metal roofed shopping malls or subways, satellite navigation will not work physically.
💡
The stability of the GPS signal depends on the visibility of the sky, and the indoor hybrid mode will always work with less accuracy.
If the problem is only seen in one particular room, interference from home appliances or a router operating in the frequency range that creates interference may be the cause.
