Have you ever noticed that maps on a smartphone show your location with an error of 50-200 meters, but taxi or delivery applications cannot accurately determine the address? The problem lies not in a weak GPS signal, but in incorrect geolocation settings on Android. Even modern flagships - Samsung Galaxy S23 Ultra, Google Pixel 8 Pro or Xiaomi 14 - can provide inaccurate coordinates if key parameters are not activated.

In this article we will look into it all ways to improve the accuracy of geolocation: from basic settings in the smartphone menu to hidden engineering modes. You will learn how to make Android use not only GPS, but also data from mobile towers, Wi-Fi networks and even a barometer (if your device has one). And also - why sometimes disabling the energy-saving mode increases accuracy by 30-40% and how to check it in practice.

Why geolocation does not work accurately: 5 main reasons

Before setting up your smartphone, it is important to understand what affects the error in determining coordinates. Even if you have GPS turned on, accuracy depends on a combination of several factors. In cities with tall buildings or indoors, the satellite signal weakens. accuracy depends on a combination of several factors:

  • 📶 Weak GPS signal. In cities with tall buildings or indoors, the satellite signal weakens. Android automatically switches to less accurate sources (mobile towers, Wi-Fi), but this can be fixed.
  • ⚡ Energy saving mode. Many manufacturers (e.g. Xiaomi, Huawei, Oppoaggressively limit background activity, including GPS scanning. This saves battery, but reduces accuracy.
  • 🔄 Outdated version of Google Play services. Location algorithms are updated every 1–2 months. If the services have not been updated for a long time, the smartphone will use less effective methods.
  • 📱 Hardware limitations. Budget models (for example, Redmi Note 12 or Samsung Galaxy A14) are often equipped with simplified GPS modules that catch the signal worse.
  • 🛠️ Software failures. Sometimes system errors disrupt the calibration of sensors. This can be treated by resetting the settings or flashing the firmware.

Interesting fact: in tests of 2026 Google Pixel 7 Pro with the activated mode High accuracy and updated services showed an error of up to 3–5 meters in open areas, while Samsung Galaxy A54 in the same place there was a scatter of up to 15–20 meters due to a weaker GPS module.

⚠️ Attention: If you use custom firmware (for example, LineageOS or Pixel Experience), the geolocation accuracy may differ from the standard one. Some builds remove proprietary GPS drivers for compatibility, which leads to errors.

Basic geolocation settings: what to enable first

Start by checking the basic settings. Most problems can be resolved at this stage if you have not previously changed the settings manually.

Open the menu Settings → Security and location → Geodata (on some devices the path may be different: Settings → Location). Here you need:

  1. Enable the switch Geodata (if it is turned off, no applications will be able to determine your location).
  2. Select mode High accuracy (on some smartphones it is called GPS accuracy or All sources). This mode uses GPS, Wi-Fi, mobile networks and sensors for maximum accuracy.
  3. Activate option Scanning is always available (or Search for devices on Samsung). This allows Android to use Bluetooth and Wi-Fi to clarify coordinates even when the screen is off.

After changing the settings, restart your smartphone. This is necessary for the system to apply the new settings to background processes.

If after these steps the accuracy does not improve, proceed to the next section.

Hidden settings: how to force Android to use all sensors

Manufacturers often hide advanced geolocation settings so as not to confuse ordinary users. But they can be activated through engineering menu or special commands.

The most reliable way is to use USSD codes (they work on most devices, except some models Huawei and Honor):

  1. Open the application Phone and enter: 
    ##1472365##

    This will open the menu GPS Test (on some smartphones the code may not work - then try ##3214789650##).

  2. In the GPS Test menu, press Start Test and wait until the smartphone finds satellites. If after 2-3 minutes no satellites appear, the problem is in the hardware.
  3. Check the parameter TTFF (Time To First Fix) - time until the first determination of coordinates. Normal value: 10–30 seconds in open areas. If TTFF > 1 minute, calibration is required.

For devices Samsung there is a separate code: 

#0#

It opens the service menu, where section Sensor you can test the operation of the GPS module.

⚠️ Attention: Do not change other parameters in the engineering menu if you do not know their purpose. Incorrect settings can lead to malfunctions of the modem or camera.
What to do if the codes USSD not working?

If your smartphone does not respond to USSD codes, try installing the application GPS Status & Toolbox from Google Play. It allows you to manually calibrate GPS, reset AGPS data and test accuracy without an engineering menu.

Optimizing Google services for maximum accuracy

Google Play Services play a key role in determining location. They use a database of Wi-Fi points and mobile towers to clarify coordinates, even when the GPS signal is weak. If these services are outdated or not working correctly, accuracy drops.

Do the following:

  • 📲 Update Google Play Services i Google App to Play Market. Go to application settings, find them in the list and click Update.
  • 🔄 Reset cache and data Google Play Services:
    1. Go to Settings → Applications → Google Play Services.
    2. Click Storage → Clear cache and Clear data.
    3. Reboot your smartphone.
  • 🌍 Turn on Google Location History (if privacy is not important to you). Google locations Google Settings → Google account management → Data and personalization → Location history.

    • After resetting the cache Android will re-download AGPS (Assisted GPS) data, which speeds up satellite searches. This process may take up to 5 minutes - not. be alarmed if immediately after resetting the GPS will work worse.

    Action Effect on accuracy Application time
    Update Google Play Services Improvement on 10–25% Instantly
    Clear cache Google Play Services Accelerate satellite search Up to 5 minutes
    Turn on Location history Accuracy in cities +15–30% After 12–24 hours
    Compass calibration Reducing the error by 5–10% Instantly

    Energy saving vs. accuracy: how to find balance

    One ​​of the main enemies of precise geolocation is energy saving modes. Manufacturers are aggressively optimizing battery consumption by disabling background processes, including GPS scanning. For example, on Xiaomi in Ultra Battery Saver geolocation mode can determine the location with an error of up to 500 meters.

    What to do:

    • ⚡ Disable power saving mode for applications that need precise geolocation (for example Google Maps, Yandex.Navigator, Uber). To do this:
      1. Go to Settings → Battery → Application energy saving.
      2. Find the desired application and select Without restrictions.
  • 🔋 On Samsung disable the option Adaptive battery in the battery settings. It limits background activity, including GPS.
  • 📵 For Huawei and Honor add navigator applications to Protected applications (section Battery → Launching applications).

    • If you are using Android 12 and newer, check the settings Adaptive energy saving in the Battery → Modessection. This algorithm automatically limits. GPS, if the smartphone detects that you have not used navigation for a long time.

    adb shell settings put global adaptive_connectivity_enabled 0

    This requires connecting the smartphone to the PC and turning on USB debugging mode.-->

    Problems with hardware: when the GPS module is to blame

    If all software methods have been tried, but geolocation still works poorly, the problem may be hardwareHere are signs of a faulty GPS module:

    • 📡 The smartphone does not find a single satellite even in open areas (checked through GPS Test or GPS Status).
    • 🔄 The accuracy has deteriorated sharply after a fall or moisture.
    • 🔧 An error is displayed in the engineering menu GPS Hardware Failed.
    • 📱 Navigation works only when connected to the mobile data (that is, tower data is used, not GPS).

    In such cases, only repair will help. Cost of replacing the GPS module:

    • Budget smartphones (Redmi, Realme, Samsung A-series): 1 500–3 000 ₽.
    • Flagships (Samsung S/Ultra, iPhone, Google Pixel): 3 000–6 000 ₽.
    • Old models (manufactured before 2018): 2,000–4,000 ₽ (sometimes it’s cheaper to buy a new smartphone).

    Before repair, check that whether the GPS antenna has gone wrong after disassembling the case. For example, after replacing the battery or display, technicians sometimes forget to connect the GPS module cable.

    ⚠️ Attention: On some smartphones (for example, Sony Xperia or LG) the GPS module is integrated into the main board. Its replacement requires soldering and costs 8. 000–15,000 ₽. In such cases, it is more advisable to buy a new device.

    Additional life hacks for maximum accuracy

    If you want to get the most out of geolocation, use these tips:

    • 🧲 Compass calibration. Open Google Maps, click on the blue dot of your location and select Calibrating the compass. Follow the instructions on the screen (you need to rotate the smartphone in the air in a figure of eight).
    • 📡 Using an external GPS antenna. For professional tasks (for example, geodesy or hunting), you can connect an external GPS receiver via Bluetooth. Popular models: Bad Elf GPS Pro, Garmin GLO 2.
    • 🌐 Alternative applications for navigation. data-i="231">works poorly, try: Google Maps doesn't work well, try:
      • OSMAnd —uses offline maps and supports external GPS receivers.
      • Locus Map —allows you to manually correct data from sensors.
      • GPS Essentials —shows detailed information about satellites and signal.
      • 🔄 Reset network settings. Sometimes errors in the mobile data configuration interfere with location determination. Reset the settings in Settings → System → Reset → Reset Wi-Fi, mobile network and Bluetooth settings.

        • For owners root-rights there is another way: editing the file gps.conf in the system partition. In it, you can manually specify AGPS servers for your region, which will speed up the search for satellites. However, this is risky - an error in the file can lead to complete GPS inoperability.

        💡

        If you often use navigation in the forest or mountains, disable the option in the geolocation settings Use location data from Google. Far from cities, it only interferes, forcing the smartphone to search for non-existent Wi-Fi networks.

        FAQ: Answers to frequently asked questions

        Why geolocation works accurately in Google Maps, but poorly in other applications?

        Google Maps uses its own coordinate correction algorithms that are not available to other applications. In addition, Google has access to a database of Wi-Fi points and mobile towers, which allows you to clarify the location even with a weak GPS signal. To improve accuracy in other applications (for example, Yandex.Navigator or 2GIS), enable the mode High accuracy in the geolocation settings and add these applications to energy saving exceptions.

        Is it possible to improve GPS accuracy without the Internet?

        Yes, but with limitations. Without the Internet, the smartphone will not be able to use data from mobile towers and Wi-Fi to correct coordinates, so the accuracy will depend only on the GPS module. To improve it:

        1. Use the mode GPS only (it turns it off). auxiliary sources, which without the Internet only interfere).
        2. Keep the smartphone in an open space, away from buildings and trees.
        3. Wait until the smartphone finds at least 8-10 satellites (checked through GPS Status).

        In this mode the error will be 10–50 meters (depending on the smartphone model).

        Why did geolocation begin to work worse after updating Android?

        This is a common problem, especially after major updates (for example, with Android 12 on Android 13Reasons:

        • Geolocation settings have been reset (return the mode High accuracy).
        • Services have been updated Google Play, but not all modules are compatible with the new version Android.
        • The manufacturer has added new restrictions on background activity (check your battery settings).

        Solution: clear the cache Google Play Services, restart your smartphone and check the accuracy after 10-15 minutes.

        How to check if the GPS module is working on smartphone?

        The most reliable way is to use the application GPS Test or GPS Essentials. They show:

        • The number of satellites found (norm: 8-12 in open areas).
        • Signal level (must be above 30 dB).
        • Time to first fix (TTFF, norm: < 30 seconds).
        • Accuracy (error in meters).

        If the application does not find any satellite within 5 minutes, the GPS module is faulty or disabled at the level firmware.

        Can I use a smartphone as an external GPS receiver for another device?

        Yes, for this:

        1. Install the application on your smartphone GPS Server or Bluetooth GPS Provider.
        2. Connect it via Bluetooth to the device, which needs coordinates (for example, a tablet or laptop).
        3. In the settings of the client application (for example, Google Maps on a tablet), select an external GPS receiver.

        This is useful if your main device has a weak GPS (for example, some tablets), and your smartphone has a good module.
