Owners of budget smartphones often face the need to fine-tune navigation modules immediately after purchase. Xiaomi Redmi 9, a popular model of the mid-segment, is equipped with a standard set of sensors, but the software shell MIUI has its own features of resolution management. Without the right configuration, maps can work slowly, and navigators can lose signal in dense development.
Geolocation is not just a button in the curtain, it is a complex mechanism for the interaction of satellites, cell towers and Wi-Fi networks, and for taxis, delivery services and messengers to work properly, the system needs to be given access rights. In this article, we will discuss in detail how to activate GPS-Module, adjust accuracy and eliminate typical positioning errors on your device.
It’s worth noting that aggressive battery optimization in Xiaomi firmware sometimes forces background geo-positioning processes to shut down, which can cause the navigator to freeze when the screen is off. Understanding how Android works on MIUI will help you avoid these situations and ensure stable coordinate transfer at any given time.
Basic GPS activation through curtain and settings
The fastest way to start a satellite search is to use the Quick Access Panel. Swipe your finger from the top edge of the screen down to open the notification curtain. Find an icon labeled "Location" or "GPS" and tap it to illuminate it. This action instantly activates the navigation hardware module.
If the icon is not in the visible area, swipe right or click on the edit button (usually a pencil or three dots) to add a widget to the main screen of the panel. However, turning on through the curtain activates only the basic mode. For full operation, it is recommended to go to the deep system settings through the Settings menu → Additional → Privacy → Permissions Management.
In this section, you'll see a list of all the apps installed. Find the navigator or messenger you need and make sure the slider opposite the "GeoData" item is activated. The system can suggest you choose access mode: "Only when in use", "Always" or "Request every time." For navigators, it is critical to choose the "Always" option so that the route does not reset.
⚠️ Warning: Selecting Always mode for geodata may slightly increase battery consumption, but ensures continuous track recording in navigation applications.
High accuracy and signal sources
Modern smartphones use a combined method of determining the coordinates. To get the Redmi 9 to give the most accurate result, you need to activate the high-precision mode. Go to Settings → Location → Mode (or “Sources”). Here you should select the option “High accuracy” (GPS, Wi-Fi and mobile network).
In this mode, the device uses GPS/GLONASS satellites for rough positioning, and Wi-Fi networks and cell towers help to clarify the location of indoors or in the canyons of streets. Without the Wi-Fi module, accuracy in a city can drop to several tens of meters, which is critical for calling a taxi.
Also available on this menu is the Google Accuracy Improvement feature, which allows you to transfer anonymous location data to Google for map calibration. While this improves the quality of the positioning, some users prefer to disable this option for the sake of privacy. Standard calibration is usually enough for household tasks.
💡
For maximum indoor accuracy, be sure to turn on Wi-Fi even if you're not connected to a particular network.Scanning the available points helps the phone determine your coordinates faster.
Managing permissions for specific applications
MIUI system strictly controls the access of applications to personal data. Even if GPS is enabled globally, a particular application may not be allowed to use it. Go to Settings → Applications → All applications, select the desired program (for example, Yandex.Maps or Uber) and find the section "Permissions".
Here you'll see a detailed list of rights. Find the "GeoData" item and make sure it's allowed. If you're using activity trackers or family locators, they may need background access. In MIUI, this sometimes requires additional confirmation or configuration in the "Battery" section.
Notice the pop-ups. When you first start an application, the system may ask for permission to access the location. If you accidentally click "Disable," you'll have to manually fix it in the settings. Without that, the app simply won't be able to show your current point on the map.
- 📍 Exact location: Allows the application to use GPS-satellites for determining coordinates with an accuracy of several meters.
- 📡 Approximate location: Defines a neighborhood or city based on cell towers, saving battery life.
- 🔄 Background access: Allows an application to track movements even when it is rolled up or the screen is off.
- 🚫 Disallows access: Completely blocks any attempts by the program to obtain data about your geolocation.
⚠️ Note: If the taxi app doesn’t see you on the map, check if it has a ban on accessing geodata in the background.
☑️ Checking the application settings
Optimizing battery life for navigation
Xiaomi's energy-saving algorithms are known for being aggressive, they can force navigation to kill if they think an app is consuming too much power, and to avoid signal loss, you need to set up autostart and no restrictions on navigation programs.
Go to Settings. → Battery and performance (or through settings search) Find a list of apps and select your navigator. Set Unlimited mode. This will prevent the system from turning off the system. GPS-module for this application, even if the screen is turned off.
Also remember to enable auto-start. Find the Security app (green zipper icon), go to Permissions → Auto-Start, and activate the switch for the right program, which ensures that after the phone is restarted, the navigation will work correctly without your intervention.
| Setup parameter | Recommended value | Impact on work |
|---|---|---|
| Energy conservation | No restrictions. | Prevents GPS shutdown in the background |
| Auto-start | Included. | Guarantees the start of service after the reboot |
| Notifications | Permitted. | Allows you to see the navigation status in the curtain |
| Working in the background | Permitted. | Critical for trackers and taxis |
Why is the route resetting?
Calibration of compass and elimination of errors
Sometimes the arrow on the map points the wrong way, or jumps around the corner, which means that the digital compass needs calibration, and the built-in magnetic field sensors can get lost because of metal car bodies or magnetic cases.
To calibrate, go to Google Maps. Tap the blue dot that indicates your location, and select Calibrate your compass. Follow the instructions on the screen: You usually have to steer your phone in the air, drawing the number eight, which helps the system re-identify the cardinal directions.
If calibration doesn't work, try turning flight mode on and off (Air Mode) and this will restart all radios, including GPS and cellular, and it's also effective to clear the cache of Google Play services that handle geodata.
- 🧲 Magnetic interference: Remove the magnetic clasp case if the compass needle is behaving unstablely.
- 🏢 Canyon effect: In the city center between tall buildings, the signal can be reflected, giving an error to the level of the sky. 20-30 meters.
- 🌦️ Weather conditions: Dense cloudiness or thunderstorms can temporarily impair satellite signal reception.
Diagnostics and resetting GPS settings
In cases where the phone doesn't see satellites at all, a deeper diagnosis may be needed. Redmi 9 has an engineering menu, but it's safer for the average user to use proven reset methods. First, try just rebooting the device.
If the problem persists, go to Settings. → Advanced settings → For developers (if the menu is hidden, click 7 times on "Version" MIUI» Find the debugging or location section and check if it includes test modes that can block real navigation.
A radical but effective method is to reset your network settings, which won't delete your photos or contacts, but will bring back your Wi-Fi, Bluetooth and other settings. GPS To the factory values. → Connection and sharing → Resetting Wi-Fi, Mobile Internet and Bluetooth.
⚠️ Note: After resetting your network settings, you will have to re-enter passwords from all Wi-Fi networks and re-enter Bluetooth devices.
💡
If none of the software methods helped, perhaps the problem lies in the hardware part of the antenna, which requires contacting the service center.
