Navigation problems on a smartphone can make a trip a nightmare, especially when the device is showing off where you are or looking for satellites for a long time. Xiaomi Redmi Note 8 Pro is a popular model that, despite the powerful MediaTek Helio G90T processor, sometimes faces software glitches in the geolocation module. This can be caused by a firmware update, MIUI malfunctions or physical obstacles.
Fortunately, most problems are solved by software calibration, which returns accuracy to the positioning without having to visit a service center. In this article, we will look at all the effective ways, from simple settings to advanced methods using an engineering menu. It is important to understand that software calibration will not help if the damaged itself. GPS-But it's the software that's the part of the device or the antenna inside the body.
Before you get to the tricky part, you need to make sure that the basic settings are correct. Often users forget to turn on high-precision mode, relying only on satellites, which in urban conditions leads to significant errors. We will discuss how to properly configure the Redmi Note 8 Pro for stable navigation.
Diagnostics and preparation for calibration
The first step is to determine exactly what the fault is. If the navigator is just slow to locate, it can be a cold start problem, not a breakdown. However, if the dot on the map is walking through buildings or flying away in a field, you need to intervene. Check the module's operation using specialized tools such as GPS Test or GPS Status & Toolbox. These applications will show the number of satellites visible and the signal level.
Make sure that the settings on your smartphone activate geolocation, Wi-Fi and mobile networks. Without the use of data from cell towers and Wi-Fi networks, initial positioning can take up to several minutes. It’s also worth checking if the power saving mode is turned on, which often limits background work. GPS-battery-saving module.
Before starting cache cleaning and resetting procedures, it is recommended to go out into the open space. Indoors, especially with metal structures or thick walls, the satellite signal may be too weak to perform a qualitative calibration. The window can also significantly shield the signal, so the best result is achieved outside.
⚠️ Note: If your smartphone has recently been in water or been hit hard, the software calibration may not work, and in such cases, the antenna may be physically displaced or the contacts oxidized.
Basic settings and Google data reset
The easiest and safest method is to reset the accumulated location data on the Android system. Over time, the satellite almanac file can become outdated or corrupt, leading to errors in the coordinate calculations. For the Redmi Note 8 Pro, this procedure is completely safe and does not require superuser rights.
You need to go to the settings menu and find the app section. The path may vary slightly between versions of MIUI, but the logic remains the same.
- 📍 Open the Settings. → Annexes → All applications.
- 📍 Click on three dots in the corner of the screen and select "Show system processes".
- 📍 Find the list of Google Play Services and Google Play Store".
- 📍 Go to "Memory" and click "Clear Cache" and "Clear all data".
Once the data is cleaned, you need to restart the device, which will start the process of re-synchronization with the satellites. Don't worry if the first navigation turn on takes longer than usual, the system loads fresh almanacs of orbits.
☑️ Checking basic settings
If the problem persists, check to see if you have a third-party app that blocks access to geo-location or changes coordinates (so-called “fake GPS”), which often conflicts with Xiaomi’s system services.
Use of the Engineering Menu for Calibration
A more advanced method is to use an engineering menu available through a standard phone call, and in MediaTek-based smartphones, such as the Redmi Note 8 Pro, the tool allows you to control the parameters of the communication and navigation module at a low level.
You need to type a special code to enter the menu, and be careful, changing unknown parameters in the engineering menu can cause the radios to work in an unstable way, and we're only interested in the Location or GPS section.
##3646633##Once you enter the code, you'll open the Engineer Mode interface, and you'll go to the Location tab, then you'll select Location Based Service, and you can reset AGPS, which often helps if the phone is stuck at old coordinates. Press YGPS to see the satellite list, and check the AGPS tab for reset.
What if the code doesn't work?
In the YGPS section, you'll see information about visible satellites. If the list is empty, click Full in the AGPS section to force the data to be uploaded. This action initiates a request to Google or MediaTek servers to get current ephemerides.
Calibration by means of ADB-team
For users who are not afraid of the computer and command line, there is a method of calibration through debugging by USB. This method allows you to send a command to a full reset configuration GPS-a module that is more efficient than a conventional cache cleaning in the settings. ADB (Android Debug Bridge on PC and enabled debugging USB smartphone.
Connect the Redmi Note 8 Pro to your computer with a cable. Make sure that the debugging permission appears on your phone screen and you have confirmed it. Open the command prompt or terminal in the ADB folder and enter the command to check the connection: adb devices. If the device appears in the list, you can proceed to reset.
The command to reset geolocation settings is as follows:
adb shell am broadcast -a com.android.gps.status.ACTION_GPS_STATUS -c android.intent.category.DEFAULTAlternatively, you can use a command to clear the data of a specific location component without logging into the settings menu:
adb shell pm clear com.android.location.fusedThis method is especially useful if the system interface is not working properly or the settings menu is not available. After completing the commands, be sure to restart the device and give it 5-10 minutes to search for satellites outdoors.
💡
Use an original or quality USB cable to connect to your PC. Cheap cables often only support charging and do not transmit data, which makes the computer unable to see the smartphone.
Specialized testing applications
If standard methods don’t work, third-party GPS-focused apps come to the rescue, allowing you to not only see the technical information, but also manage the status of the module. For Xiaomi Redmi Note 8 Pro, GPS Status & Toolbox and GPS Test applications have proven to be well-established.
The GPS Status & Toolbox app has an A-GPS Status Management feature, and you can click on it and you can select Reset and then Download. This forcefully updates the satellite position data, ignoring the system's cache, which is similar to what you do on the engineering menu, but through a friendlier interface.
| Annex | Substantive function | I need a Root. | Feature |
|---|---|---|---|
| GPS Status & Toolbox | Resetting and loading A-GPS | No. | Detailed information on satellites |
| GPS Test | Signal visualization | No. | 3D view of satellites and signal graph |
| GPS Essentials | Comprehensive test | No. | Testing of accelerometer and compass |
| MTK Engineering | Engineering menu | No. | Direct access to MediaTek settings |
And you also have to look at the digital compass, which is often connected to GPS, and if the arrow in the navigator is not right, the GPS calibration won't help, you need to calibrate the magnetometer, and you usually just have to spin the phone in the air with an eight or use an app to calibrate the compass.
⚠️ Note: Do not install apps called "Fake" GPS" Or "Mock Location," if you're not a developer, they can implement a virtual driver that will intercept real coordinates and broadcast false data to all applications.
Influence of covers and accessories on the signal
Often the cause of bad signal is external factors that users forget. Redmi Note 8 Pro has antennas located in certain areas of the case. If you use a case with metal inserts, magnetic fasteners or just a very thick protective case, it can shield the signal.
If you take the case off and test it outside, if you don't have the case, the satellites are instantaneous, and the signal is lost in the case, the accessory is the problem, and the magnets in the car holders can (interfer) with the magnetic compass, which confuses the orientation in the navigator, although the coordinates remain correct.
In addition, a perimeter-framed metal glass can also reduce reception quality, especially in areas of uncertain reception, and only the replacement of the accessory with a more "transparent" radio wave can help.
Problems after firmware update
Xiaomi owners often face the fact that after updating MIUI geolocation settings are lost or a new bug in the system interferes with the correct operation of GPS. If the problems began immediately after the update, it is worth checking for new security patches or, conversely, roll back to the previous version if the problem is massive.
Sometimes it helps to reset all network settings. This action will delete stored Wi-Fi passwords and Bluetooth settings, but return network modules to factory state. The way to this feature: Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth.
In extreme cases, if nothing works, you may need to completely reset your device (Hard Reset).Be sure to back up the data before that, as all the information will be deleted. Clean installation of the system often eliminates software conflicts accumulated during use.
💡
If GPS stopped working after the MIUI update, the most effective solution is often to reset the network settings or completely reset the device, as the problem lies in the configuration files of the system.
