How to add a map to Xiaomi Mi 9: setting up GPS and navigation

Xiaomi Mi 9 has a powerful navigation module that supports multiple satellite systems, which ensures high positioning accuracy. However, to make the device work correctly and show current data, often requires the correct initial setup or add offline maps to navigation applications. Many users find that after buying or resetting the settings, the phone does not see satellites or displays a map with a delay.

In this article, we will examine not only the installation of applications, but also the deep system settings that affect the operation of the global positioning system. You will learn how to force the search for satellites, what resolutions are critical for the operation of the navigator and how to choose the optimal driving software in your area.

Before you get to specific actions, make sure that the basic geolocation functions are activated in the system. Without this step, no application will be able to access the coordinates, regardless of the quality of the installed software. Android on the MIUI shell has its own power management features that can block the background operation of the navigator.

Basic activation of geolocation modules

The first step is to turn on the hardware modules that communicate with satellites, and in modern smartphones, a set of sensors is responsible for this, and sometimes the system puts them into an economical mode, which reduces the speed of search. You need to go to Settings → Location and activate the slider on top. After that, you are recommended to choose a High Precision mode that uses both GPS and Wi-Fi and mobile networks.

Next, check if the system blocks navigation services in the background. Battery optimization in MIUI is often aggressive and can kill the process of downloading cards if you fold the application. Go to the battery settings, find a list of applications and set the "No restrictions" mode for your navigator (for example, Yandex.Navigator or Google Maps).

It is also important to make sure that the “Location Accuracy” function is enabled, which allows you to use data about nearby Wi-Fi points for a quick start, so-called A-GPS, which is critical for cold start navigation in the city.

Selection and installation of navigation application

Standard cards preinstalled in the system often don’t have enough functionality for drivers or tourists. AMOLED-The screen is ideal for applications with detailed graphics and voice. The choice depends on your goals: for the city in Russia and the CIS, the best suited Yandex.Navigator or 2GIS, Traveling abroad: Google Maps or Waze.

The installation process is standard: open Play Market or Mi Store, type the app name into the search box and click "Install." However, if you plan to use navigation in places with poor Internet, you will need applications that support offline cards, such as Maps.me or OsmAnd. These must be downloaded and configured in advance while you are connected to Wi-Fi.

When you first run any application will ask for permissions, and it's critical to give you access to the location in "Always" or "When in use" mode, and access to a microphone for voice control and memory for storing the cache of cards, without these permissions, the functionality will be severely curtailed.

Download and configure offline maps

Offline maps are a lifeline to save traffic and navigation in areas of unstable coverage. Unlike online maps, where the map is loaded in chunks, the offline version requires pre-downloading entire regions. In applications like Yandex.Navigator or 2GIS, you need to go to the profile menu or settings and select "Download maps".

Once you select the desired area (country, city or area), the data pack will start downloading.For Xiaomi Mi 9 with its fast Wi-Fi module 802.11ac This process will go quickly. If there's not enough memory, some applications can choose to save data on the computer. SD-The map, although modern versions of Android often limit this capability for security reasons.

Once you download, you need to check the data's relevance. The road network changes all the time, new interchanges appear, the traffic pattern changes. It's critical to update offline maps at least once a month so that the navigator doesn't take you down a closed road. The app's settings usually have an "Auto-Update Maps" option that you should activate.

💡

Use the “Download over Wi-Fi” function in the navigation settings so that you do not accidentally consume mobile traffic when updating cards in roaming.

Calibration of compass and sensors

Even with a satellite signal, the direction of movement on the screen can be displayed incorrectly if a calibration magnetic sensor is knocked down, which often happens after the phone falls or being near powerful magnets (for example, in a car holder with a magnet). On the Xiaomi Mi 9, where the Hall sensor and magnetometer are built into the case, the calibration is programmatic.

To do this, open Google Maps, click on the blue dot of your location, and select Calibrate. The system will ask you to steer your phone in the air, drawing an eight, so that the device can understand where north is relative to its current position in space.

If standard calibration doesn't work, you can use specialized tools from the Play Market, such as GPS Status & Toolbox, which allows you to see raw data from satellites and perform an A-GPS reset, which often helps shake up the module and make it recalculate coordinates from scratch.

Table of popular navigation applications

The choice of software depends on the specific tasks, and below is a comparison of the main characteristics of popular solutions for your model.

As you can see from the table, 2GIS and OsmAnd are best suited to work fully without the Internet. However, if you need real-time traffic information, you will have to sacrifice traffic and choose Yandex or Google. Xiaomi Mi 9 easily copes with rendering heavy graphics of any of these applications.

Solving Location Problems

Sometimes users are faced with a situation where the navigator writes "Satellite Search" endlessly. This can be caused by a software failure in the Android geolocation service. First of all, try to reboot the smartphone. This trivial action resets the suspended driver processes.

If the reboot didn't help, check if the flight or energy saving mode is on.In power saving mode, Xiaomi can limit the poll frequency GPS-It's also worth checking the date and time: if they're downed, security certificates to connect to the servers. A-GPS The phone may not work and the phone may not be able to get the initial coordinates.

⚠️ Warning: If you use a metallic-laced protective glass or magnetic case, they can shield the antenna signal from the top of the case.

In rare cases, network settings are required. Go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. This action will not delete your personal files, but will return network settings to factory values, which often solves problems with transmitting auxiliary data to GPS.

💡

A permanent loss of GPS signal in motion most often indicates a software conflict or problem with the antenna module, rather than a chip failure.
