Modern Xiaomi Redmi and Poco smartphones are powerful navigation devices that cannot be imagined without a properly functioning GPS module. Activation of location services is necessary not only for maps, but also for taxis, food delivery, search for a lost device and even for some security features. In the Android operating system with the shell of MIUI, this process can have its own nuances that often put users at a loss.
Proper geolocation settings provide high positioning accuracy, which is critical in an unfamiliar city or emergency call for emergency services. Many device owners face a situation where the navigation icon is on, but applications do not see the coordinates, or the battery is discharged too quickly due to unoptimized settings. Understanding the principles of A-GPS and Wi-Fi scanning modules allows you to significantly improve the response of the system.
In this article, we will take a look at all the activation methods, from fast switches to deep engineering settings. You will learn how to make the navigator work faster and why it is sometimes worth sacrificing autonomy for the sake of accuracy. The accuracy of determining the coordinates on Xiaomi depends on the simultaneous operation of GPS, GLONASS and scanning Wi-Fi networks, even if you are not connected to the router.
Quick activation through the control panel
The easiest and most obvious way to run navigation services is to use the top notification curtain, which is suitable for 90% of cases when the user urgently needs to call a taxi or show the person their location in the messenger, just swipe down the screen from top to open the control panel, and find an icon with an arrow or compass.
However, in some versions of MIUI firmware, this icon can be hidden in the second page of the Quick Settings menu, which requires you to swipe left or click the edit button (usually a pencil or three dots) to display hidden elements.
If the standard icon doesn’t show up or work, it may indicate a system failure of the launcher interface, in which case it is recommended to restart the device or check for system updates. Sometimes it helps to clean the cache of the Security application, which in the shell of Xiaomi controls many system permissions.
💡
If the GPS icon is missing from the curtain, try changing the theme to standard – some third-party themes hide the system switches.
Deep configuration through the parameter menu
For a more slim configuration, you need to go to the full smartphone settings menu, where the user accesses the control of modes of operation that affect the cold start speed and energy consumption. The path to the desired section usually looks like: Settings → Additional → Privacy → Geolocation services, although depending on the version of Android, the path may vary slightly.
Inside this menu, you can access the Use Geodata switch, which is a master switch for all applications, and below you can choose between high accuracy, charge savings, or only the device's sensors. The choice of the “High Accuracy” mode involves GPS-Wi-Fi, mobile network and module at the same time.
The section “Application permissions” deserves special attention. Even with global GPS enabled, a particular application (for example, Yandex.Maps) may not be allowed to access coordinates. You need to go to the settings of each navigator and make sure that the resolution is “Always” or “When using the application”.
☑️ Verification of geolocation settings
Importantly, newer versions of MIUI have added the “Precise Location” feature, which can be turned on or off for each application separately, allowing for example, giving the weather widget approximate city coordinates and the navigator accurate data up to a meter, which increases overall data security.
Using the Engineering Menu for Diagnostics
If standard methods don't work and the navigator is slow or can't see satellites, you should turn to the hidden engineering menu, which is for developers and service engineers, but is also available to ordinary users for hardware diagnostics.
For most Xiaomi devices with MediaTek and Qualcomm processors, code ##3646633## runs. Once you have the combination set, the phone will automatically go to the engineering menu. If the code doesn't work, your model may require the MTK Engineering Mode app from the Google Play store.
In the menu that opens, you can go to the Location or LocationBasedServices tab, where you can see satellite connection status, signal level, and trigger a forced search for A-GPS data. YGPS allows you to visually observe the search for satellites on the map and clear the almanac cache, which often solves the problem of long search.
⚠️ Warning: Changing unknown parameters in the engineering menu can lead to unstable operation of the radio module. Do not change the settings that are not sure, use only the browsing and resetting functions of the cache.
What if the code doesn't work?
Adjustment of accuracy and operating modes
The quality of navigation depends on the selected data sources. In the geolocation menu, Xiaomi offers several optimizations that are worth considering, especially for scanning Wi-Fi and Bluetooth networks, and even if the wireless modules are turned off, the system can use them to find the nearest access points and refine the coordinates.
For maximum efficiency, it is recommended to enable the option “Always Allow Scanning” in advanced Wi-Fi settings.This allows the phone to use hotspot databases to instantly determine the location, which is especially true in dense urban areas where satellite signals can be reflected from buildings.
Also worth noting is the calibration of the compass, which is often required after resetting or replacing the case. Apps like Google Maps will offer to calibrate the sensors if they notice inaccuracies. Regular calibration improves the orientation on the map when you stand still.
| Mode of work | Modules used | precision | Impact on the battery |
|---|---|---|---|
| High precision | GPS, GLONASS, Wi-Fi, Mob. | Up to 5-10 meters | High. |
| Saving charge | Wi-Fi, Mob network (without GPS) | Up to 100-500 meters. | Low. |
| Only the device | Only GPS/GLONASS | Up to 10-20 meters. | Average. |
| Off. | No. | Absent. | Absent. |
Solving Location Problems
It's quite common for geolocation to be enabled, but no coordinates are identified or jumping, often because of outdated satellite almanac data or application conflict, and the first step should always be to clean up the cache of Google Play services and the map application itself.
Another common problem with Xiaomi is its aggressive power-saving system, which can force the background navigation process to stop if the screen is gone, so to avoid this, you need to go to the battery settings, find the map app, and select No Limits mode.
If the problem persists, perhaps it's the case. Metallic or too thick protective cases can shield the signal of the antenna, which in Redmi smartphones is often located at the top or bottom of the case.
Optimizing GPS for navigation
For those who use a smartphone as their primary navigator in a car or camping trip, additional settings are important, especially when it comes to downloading auxiliary data, and applications can use the network to load up the current position of satellites, which speeds up the first start (Time To First Fix).
It is also worth checking whether the flight mode is switched on accidentally, as it blocks the transmission of data necessary for the flight. A-GPS, though GPS-The module can work. To work fully offline, you need to download maps of the region in advance in the navigator application.
An important aspect is to update system time: if the device time is downed, security protocols will not allow you to establish a connection with satellites. Make sure that the date and time settings are ticked with the "Use network time".
⚠️ Note: When using navigation mode 3D-The processor of the smartphone heats up with detailed graphics cards, which can lead to trottling and temporary deterioration of the signal reception quality.
💡
The combination of downloaded offline cards and enabled mobile internet for A-GPS gives a better balance between speed and traffic consumption.
