Modern smartphones Samsung have become indispensable assistants in navigation, finding the nearest cafes and tracking physical activity. However, many users are faced with a situation where maps cannot determine location or applications require access to geodata. Enabling GPS module is the first and most important step for the correct operation of all services that depend on your coordinate.
In this article we will look in detail at how to activate the geolocation function on devices running Android in the shell One UI. You will learn not only about basic settings, but also how to optimize navigation to save battery power and increase location accuracy.
The activation process may vary slightly depending on the version of the operating system and the model of your gadget. Whether it’s a new flagship Galaxy S24 or a more affordable series Galaxy A, the basic principles of configuration remain the same for the entire ecosystem of the South Korean giant.
Quick activation through the notification panel
The easiest and fastest way to enable navigation is to use the quick settings panel. This method does not require deep diving into the menu and only takes a few seconds. Simply swipe down from the top of the screen to expand the notification panel.
If the geolocation icon is inactive, it is usually grayed out. You need to find an icon with an image of a pin or a compass, which is labeled as "Geodata" or «Location». Click on it once so that it is highlighted with an active color, most often blue or cyan.
In some versions of the shell One UI icons may be hidden on the second page of the panel. To do this, swipe left or click the edit button (usually three dots or a pencil) to add the desired switch to the main quick access screen.
⚠️ Attention: If after clicking on the icon it immediately turns gray again, you may have power saving mode enabled, which forcibly turns off communication modules.
You can add a widget to instantly turn on GPS “Geodata switch” directly to the desktop through the widget menu, so as not to open the curtain every time.
Deep customization through the settings menu
For more detailed control over the operation of navigation systems, you should go to the main device settings. This path allows you not only to enable the function, but also to configure location modes that affect the accuracy and speed of operation.
Open the application Settings and find the section "Location". Depending on the regionalization of the firmware, this item may also be called “Geodata” or located within the “Connections” category. After entering the menu, make sure that the main switch is in the active position.
The choice of method for determining coordinates is also available here. The system Android offers several options: using only GPS satellites, only Wi-Fi networks and mobile towers, or a combined mode. For everyday use, the optimal option is "High accuracy", which uses all available signal sources.
- 🌍 High accuracy: uses GPS, Wi-Fi and mobile networks for the fastest and most accurate determination.
- 📡 Device only: works exclusively via GPS satellites, which saves traffic, but takes longer to search for a signal indoors.
- 📶 Battery saving: determines location only by cell towers and Wi-Fi without turning on the GPS chip.
Setting permissions for specific applications
Even if the global geolocation module is active, individual apps may not have access to your coordinates. This is an important function securitythat prevents surveillance by unscrupulous software.
To check access rights, go to the menu Settings → Applications. Select the application you are interested in, for example Google Maps or Yandex.Navigator. In the list of permissions, find the “Location” item and make sure that access is allowed.
Modern versions Android allow flexible configuration access policy. You can allow an app to use location data only while you're using it, always (even in the background), or deny access completely. For navigators, it is critical to select the “Allow always” or “Allow only while in use” option, otherwise the route may be interrupted when the screen is off.
Settings → Applications → [Selected application] → Permissions → LocationWhy does the application ask for access in the background?
Some activity trackers and taxi services require constant access to GPS to correctly calculate the distance traveled or track an order, even when the smartphone screen is turned off.
Improving signal accuracy and calibration
Sometimes users complain that the “blue dot” on the map jumps or shows the wrong direction. This may not be due to a breakdown, but to the need to calibrate the sensors or incorrect settings of auxiliary services.
In the location menu, find the item "Improving accuracy" or "Google Geolocation accuracy". Activating this function allows the smartphone to use databases of Wi-Fi access points and cell towers to clarify coordinates received from satellites. This is especially useful in urban areas where the direct view of the sky is limited.
It is also worth checking the compass operation. If the navigation is showing you the wrong direction, try doing the figure eight exercise while holding your phone in your hand. Rotate the device in space, describing the number 8, so that the magnetic sensor is recalibrated.
| Parameter | Impact on accuracy | Impact on battery |
|---|---|---|
| GPS only | High on outdoor, low indoors | Medium |
| Wi-Fi scanning | Increases accuracy in buildings | Low |
| Bluetooth scanning | Helps in shopping centers | Low |
| High accuracy (All) | Maximum | High |
Do not forget that covers with metal inserts or magnetic mounts can shield the antenna signal. If you notice a sharp drop in the quality of navigation, try removing the case and checking the system again.
A combined mode using Wi-Fi and Bluetooth gives the best results in dense urban areas and indoors.
The influence of the power saving mode on GPS
One of the common reasons for shutdowns geolocation is an active energy saving mode. The system Samsung automatically limits background processes and disables power-hungry modules to extend battery life.
If you have “Power Saving” or “Maximum Saving” mode enabled, the phone may block the search for GPS satellites when the screen is off. This leads to the fact that the navigator stops plotting a route or the activity tracker stops recording.
To solve this problem, it is not necessary to completely disable battery saving. You can add the required applications to the exclusion list. Go to Settings → Device maintenance → Battery → Background restrictions and make sure that your navigation apps are not in the "Applications in sleep mode" list.
⚠️ Attention: The battery menu interface may change from time to time One UI updates. If you do not find the specified items, use the search in the settings by entering the query “Battery” or “Saving”.
☑️ Checking energy saving settings
Diagnostics and solving problems with the module
If all the settings are correct, but the phone still does not see satellites, a software problem may have occurred Location service failure. In this case, a forced restart of services or a network settings reset is required.
Try turning it on and off Airplane mode. This action restarts all radio modules of the smartphone, including GPS, Wi-Fi and Bluetooth. Often, such a simple manipulation helps the device quickly capture a signal after a long period of inactivity or moving over a long distance.
In more complex cases, clearing Google geolocation service data helps. This will not delete your personal files, but it will reset the satellite data cache (almanac), forcing the phone to re-download the latest information about the position of satellites in orbit.
Settings → Applications → Show system → Google Play Services → Storage → Clear cacheIt’s also worth checking if Is the geolocation feature disabled at the Google account level? Go to the settings of your Google account through a browser or application and make sure that “Location History” is active if you use ecosystem services.
What is a cold and hot GPS start?
A cold start occurs when you first turn it on or after a reset, when the phone searches for satellites “blindly” (up to 2-3 minutes). A hot start takes seconds, since the device remembers the last coordinates.
Why does GPS work slowly indoors?
GPS satellite signals have a high frequency and do not penetrate well through concrete walls and metal structures. Indoors, the phone relies on cell towers and Wi-Fi, which is less accurate. For best performance, open a window or go outside.
Is it possible to determine the location of a switched off phone?
No, the GPS module requires power to work. However, some new Samsung models support the function of searching for a turned off device through a network of other gadgets, but this only works if the phone was turned off recently and has a residual charge in the special. contour.
How to check if GPS works at all?
Download a special application like “GPS Test” from the Play Market store. Run it in an open space. If you see a list of satellites and signal values (SNR) above 20 dBHz, then the hardware is working.
Does protective glass affect the signal?
Ordinary tempered glass does not affect the signal. However, glass coated with metal, tinted films with metal, or cases with magnetic rings for car holders can significantly weaken the signal reception of the antenna.
Why do you need the "Background Mode" permission for maps?
This permission allows the application to continue routing and voice prompts, even if you minimize the map or turn off the screen to save power. Without this, navigation will be silent when the phone is locked.
