How to improve GPS accuracy on Xiaomi smartphones: from basic settings to hidden chips

Have you ever encountered a situation where the GPS on your Xiaomi shows your location with an error of 50-100 meters? or maps for a long time “float”, can not determine the exact street, and the navigator is confused at a critical moment? The problem is familiar to many owners of smartphones of this brand – despite the powerful hardware, the accuracy of geolocation often leaves much to be desired.

The reasons can vary from basic settings that users simply don’t know to hardware limitations of specific models (like the Redmi Note 10 or the Redmi Note). POCO X3 budgetary GPS-In this article, we will discuss all working ways to improve accuracy, from the obvious (software update) to the little-known (manual data download). AGPS Important: some methods require root rights, but most are available without them.

Don't expect miracles -- if your smartphone is equipped with a low-end GPS/GLONASS module (like the Redmi 9A), even the perfect settings won't turn it into a professional navigator. But 80 percent of the time, the problem is solved software-based. Let's start with the simplest.

1. Check basic GPS settings

Before digging deeper, make sure you have all the options you need enabled.Many users don't even suspect that Xiaomi is defaulting on some features to save power.

Go to Settings → Communication and Network → Location and check:

📍 Precision mode: High accuracy must be selected (uses) GPS, Wi-Fi, mobile and Bluetooth mode Saving charge gives an error of up to 1 km!
🔄 Scanning. Wi-Fi/Bluetooth: Both points must be active – this helps to determine the location in the premises.
📱 Google Location History: If you use Google Maps, turn on this option to speed up satellite search.

Also note the settings → Battery → Power Saving Mode. If ultramode or supersaving is on, GPS will malfunction. Turn it off or add navigation apps (e.g. Yandex.Navigator or 2GIS) to exceptions.

💡

If the accuracy has not improved after changing the settings, restart the smartphone - sometimes the GPS module "hangs" and requires a reset.

2. Update of firmware and GPS module

Manufacturers regularly release updates that correct errors in the work GPS-For example, in Xiaomi Mi 11 after upgrading to the MIUI 14 Many users reported a 30 to 40 percent improvement in accuracy:

Open Settings → About the phone → System update.
If you have a new version, install it (preferably via Wi-Fi).
After the update, reset your GPS settings: go to Settings → Applications → Application Management → Three Points (menu) → Reset application settings → Select “GPS”.

It is worth mentioning the update separately. AGPS-Data (Assisted) GPS). These files help your smartphone find satellites faster:

Download the GPS Status & Toolbox app from Google Play.
Open it and press A-GPS Management → Download.
Wait until the process is completed (Internet required).

Calibration of compass and sensors

An inaccurate compass or downed motion sensors (accelerometer, gyroscope) can distort GPS data. For example, if your smartphone thinks you are moving north, but in fact east, the navigator will “shift” your location.

For calibration:

Open Google Maps or Yandex.Maps.
Shake the phone in the shape of eight (as a sign of infinity) – it will reset the gyroscope data.
For compass: In the GPS Status app, click Calibration of the compass and rotate the smartphone on all axes, as shown on the screen.

If calibration doesn't work, check the sensors with the Sensor Test app (available on the Play Market). If the accelerometer or magnetometer values are highly "jumping" even in a static position, repairs may be needed.

What if the sensors show incorrect values?

If you see that the sensors are producing chaotic data after the Sensor Test (e.g., an accelerometer shows an acceleration of 15 m/s2 at rest), this may indicate a hardware malfunction. In this case: 1. Try resetting to factory settings (Settings → Additional → Recovery and Reset). 2. If the problem persists, contact the service center. In some models (e.g., Redmi 9T), the sensors are attached to the motherboard and can depart when impacted.

4.Using third-party apps to improve GPS

Standard MIUI tools don’t always do the job of optimizing GPS, and fortunately, there are third-party tools that can make things a lot better:

Annex	Functional	Need root?
GPS Status & Toolbox	AGPS update, compass calibration, satellite mapping	No.
GPS Test Plus	Detailed GPS diagnostics, accuracy test, log preservation	No.
Fake GPS Location	Emulation of location (for tests)	Yes.
GPSTest (from Android)	The official GPS testing app from Google	No.

GPS Test Plus is especially useful, showing how many satellites your smartphone is seeing, their signal/noise (SNR), and even drawing a graph of accuracy. If you see a phone catching fewer than 5 satellites with SNR < 20, that's a sign of antenna or firmware issues.

The critical point: if you see only satellites in the list GLONASS (Russian system, but not GPS (American, this may indicate a regional firmware with limited settings. MIUI.

5. Configure GPS configuration files (for advanced ones)

Android has a hidden gps.conf file that handles satellite connectivity settings, which can be edited manually, but that requires root or ADB permissions.

Instructions for editing through ADB:

Install ADB Tools on your PC and connect your smartphone over USB (enable Debugging over USB in Settings → About Phone → MIUI version – press 7 times on the build number).
Enter the command: adb pull /system/etc/gps.conf This will copy the file to your computer.
Open gps.conf in your notebook and find the lines: NTP_SERVER=... XTRA_SERVER_1=... XTRA_SERVER_2=... Replace them with current servers (for example, for Russia): NTP_SERVER=ru.pool.ntp.org XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
Save the file and download it back: adb push gps.conf /system/etc/ adb shell chmod 644 /system/etc/gps.conf
Reboot your smartphone.

This method is especially relevant for Xiaomi owners with Chinese firmware, where AGPS servers are set up in China by default and can slow down data loading in other regions.

💡

Editing gps.conf is the most effective way to improve accuracy, but it requires caution. An error in file syntax can result in a complete GPS failure!

Hardware solutions: antennas and covers

If the software methods didn't work, the problem could be the hardware.

📶 Metal covers: they shield the signal. Try to remove the case and test it. GPS without.
🔌 Antenna damage: If the phone falls or gets wet, contact GPS-The antennas could move away. In the service, it can be repaired in 1-2 hours.
🔋 Weak battery: with a discharge below 15% GPS It starts to "glut" because it saves energy.
🌐 External GPS-antennas: for professional use (e.g. in trackers) you can connect an external antenna via a OTG.

It is also important to note that some Xiaomi models (e.g., the, POCO F3 or Mi 10T) GPS-The antenna is located at the top of the body. If you hold the phone horizontally (for example, in a car on the holder), the signal can be blocked by the hand.

✅ Remove the metal case

✅ Check the phone for dents/cracks in the top

✅ Test. GPS battery-charged >50%

✅ Try to hold the phone vertically

✅ Check the work GPS elsewhere (far from the high-rise)-->

7.Alternative methods: offline maps and caching

If GPS is not working properly, but you need to get to your destination immediately, use the offline mode:

🗺️ In Google Maps or Yandex.Maps, download the map of your region in advance (in the application settings).
📡 Turn on the plane mode, but leave it on GPS — This will remove interference from the mobile network.
🔄 Use coordinate caching: Some applications (e.g. OsmAnd) allow you to save the last known coordinates and continue navigation even when the signal is lost.

You can also try hybrid navigation:

Turn on GPS and mobile internet.
Open Google Maps and wait until your location is determined.
Switch to Device Only (without internet) mode – the cards will use the stored data.

This method will not improve the GPS itself, but it will help to avoid losing the route at critical moments.

FAQ: Frequent questions about GPS on Xiaomi

Why does my Xiaomi GPS work worse than my iPhone?

This is due to several factors: Hardware: Apple uses more accurate GPS-modules (e.g. Broadcom) BCM47755 iPhone 13, while Xiaomi often put budget chips (Qualcomm Snapdragon with integrated GPS). Software optimization: iOS is better at processing satellite signals, especially in urban environments. Antennae: iPhone antennas are positioned to minimize interference by the user. However, with the right settings (see this article), the accuracy difference can be reduced to 10-15 meters.

Can GPS be improved without root rights?

Yes, most of the methods in this article do not require root: Firmware Update and AGPS. Compass Calibration. Use of third-party applications (GPS Status, GPSTest). Setting up the accuracy mode and scanning Wi-Fi/Bluetooth. Root is only needed to edit gps.conf or install modified firmware.

Why does GPS work well on the street but get lost indoors?

This is normal behavior: GPS/GLONASS satellite signal does not penetrate walls and roofs. Indoors, the smartphone uses: Wi-Fi: locates over nearby networks. Bluetooth: if there are beacons nearby. Mobile networks: triangulation on towers (accuracy ~500-1000 m). To improve accuracy inside buildings: Turn on Wi-Fi and Bluetooth in location settings. Use Indoor Navigation-enabled applications (e.g., Google Maps in shopping malls).

How to check how many satellites my Xiaomi is catching?

To do this: Install GPS Test Plus or GPS Status. Open it and look at the Sky View screen, which will show all visible satellites. Green/blue icons are satellites with good signal, red ones are low signal or interference. Ideally, a smartphone should "see" at least 8-12 satellites, of which 5-7 are with SNR > 20.

After the MIUI update, the GPS stopped working.

This is a common problem when switching to new firmware versions. Try: Reset GPS: Settings → Apps → GPS → Storage → Clean up cache. Update AGPS via GPS Status. Reverse to the previous version of MIUI (if the problem is critical). Set up custom recovery (like TWRP) and flash the GPS module separately. If nothing helps, contact the service - the update may have damaged the system's configuration files.

If you have tried all the methods, but GPS It is still not working well, it is worth considering alternative solutions: GPS-Trackers (such as Garmin or GlobalSat) or switching your smartphone to a more accurate model (such as the Xiaomi 13 Pro with Dual-Frequency). GNSS).

Remember, GPS accuracy depends not only on the phone, but also on the environment. In the woods, in high-rise areas or in bad weather, even flagship devices can make mistakes by 20 to 50 meters.
