A modern smartphone is difficult to imagine without navigation systems that allow you not only to build routes, but also to order taxis, search for the nearest cafes or share your location with friends. Owners of the popular Xiaomi Redmi 4 model often face the need to quickly activate the GPS module, especially after resetting settings or updating the operating system. Proper geolocation is critical for many applications, and its absence can significantly reduce the usability of the device in everyday life.
The process of switching on may seem trivial, but there are nuances in the MIUI shell that affect positioning accuracy and satellite search speed. In this article, we will discuss in detail all the stages of activation, from simple switching of the toggler to deep calibration of the sensors, which will allow you to maximize the navigation potential of your gadget.
Basic activation through the notification panel
The fastest way to start a satellite search is to use the notification curtain, which is ideal for situations where you need to determine the coordinates urgently or turn on the navigator in the car, just swipe down the screen from top to bottom to open the quick access menu and find the location icon.
If you don't see the icon you want among the displays, try pushing the curtain down even lower or pressing the edit button to add a shortcut to a prominent place. Activation through this interface gives instant results, but doesn't give access to advanced accuracy settings.
Once turned on, the system will begin a background search for available satellites, which can take from a few seconds to a couple of minutes depending on the signal reception conditions, during which time it is recommended to be in open space or near a window to improve the visibility of the sky.
Configure the location parameters in the system
To fine-tune the menu, you need to go to the main settings menu of the smartphone, where the user gets full control over which data sources will be used to determine the coordinates. Navigation through the menu is carried out through the sequence: Settings → Advanced settings → Location.
Within this section, it's important to look at the location mode switch, which dictates the module's algorithm, and for maximum accuracy, you should choose a combination that uses all the available resources of the device, including Wi-Fi and mobile networks.
It is worth noting that using only GPS satellites can significantly increase the cold start time of navigation, adding network data sources allows the phone to quickly determine the approximate location, and then refine it by satellite.
☑️ Checking settings GPS
Selection of operating mode and accuracy
The Android system that runs Redmi 4 has multiple navigation profiles, and understanding the differences between them will help you balance accuracy and power consumption.
- 📡 Only GPS: It uses satellite signals, it provides high accuracy in open areas, but it's slow in the city and it uses a lot of battery.
- 📶 Network coordinates: Detects by cell towers and Wi-Fi access points. It works quickly even indoors, but has a large error margin.
- 🌍 By all sources: Combines satellite and network data, the best choice for everyday use, balancing speed and accuracy.
Switching between modes is instantaneous, but changes sometimes require restarting the navigation app to take effect. If you move frequently between rooms and the street, automatic mode will be the most convenient solution.
Redmi 4 owners are advised to always keep high accuracy on for proper taxi and delivery services.
Managing permissions for applications
Even with GPS enabled, apps may not see your coordinates unless they are given permission. MIUI security controls access to personal data, so each navigator or messenger needs to authorize separately.
Go to Settings → Applications → All applications, find the right program (for example, Yandex.Maps or Uber) and go to Permissions. Here you need to find the item “Geodata” or “Location” and select the option “Allow always” or “Allow when using”.
⚠️ Warning: Don’t give geolocation access to unverified applications, especially those that don’t require it for their primary function (e.g. flashlights or calculators.
If the application requires constant tracking (for example, to record tracks in the gym), make sure that the system does not “kill” it in the background.
Why does the app say “GPS is off”?
Calibration and acceleration of GPS
Over time or after a long trip, sensors can get confused, leading to inaccurate positioning.The Xiaomi Redmi 4 has no built-in deep calibration tool, so you will have to use third-party software or Google system features.
One effective method is to use Google Maps, open the map, click on the blue dot of your location, and select Calibrate. Follow the instructions on the screen, making the phone move as an eight.
You can also use specialized tools from the Play Market, such as GPS Status & Toolbox, which allows you to reset the almanac data and start searching for satellites again, which often solves the problem of “hanging” navigation.
| Parameter | Description | Impact on work |
|---|---|---|
| A-GPS | Assisted GPS, help with networks | Accelerates the primary definition of coordinates |
| EPO | Extended Prediction Orbit | It allows you to find satellites faster after downtime |
| Wi-Fi scanning | Search for networks even when off. Wi-Fi | Improves accuracy in cities and premises |
| Motion sensors | Accelerometer and gyroscope | Helps tracking in the absence of a signal |
💡
For quick calibration without installing programs, open Google Maps, turn on satellite mode, and wait for your current building to be clearly displayed. If the dot is offset, tap it and select the option (calibrate).
Solving Location Problems
If geolocation is on, but the phone persistently fails to see satellites or shows the wrong place, the problem may be a software failure or a physical obstacle. First of all, try rebooting the device - this is a classic but effective method of resetting radio modules.
Check if the phone has a case with a metal back panel or inserts. Metal shields the signal, and the built-in Redmi 4 antenna located at the end of the case may not be able to break through the protection.
⚠️ Warning: If the phone fell or was exposed to moisture, the antenna module could move away from the board, in which case the software methods will not help, you will need to disassemble and solder the contact.
It's also worth checking the date and time. If the system is downed, security certificates can block the connection to the A-GPS servers, making it impossible to quickly determine the coordinates. Set up automatic time synchronization over the network.
💡
If nothing helps, perform a network reset (not a full phone reset!) this will clear the cache of Bluetooth, Wi-Fi and mobile networks, often eliminating software conflicts of communication modules.
The impact of geolocation on autonomy
Constant operation of the navigation module is one of the most energy-intensive processes in a smartphone. Xiaomi Redmi 4 has a good battery, but active use of cards can discharge the device in 4-5 hours of screen. Understanding the mechanisms of energy consumption will help to extend the life of the gadget.
The main expense is not so much the reception of the signal, but rather the processing and transmission of data over the mobile Internet. High accuracy requires constant survey of sensors, which keeps the processor in suspense. To save charge on trips, you can periodically switch to Device Only mode.
Keep an eye on background apps. Often, maps or social media continue to track your movements even when the screen is off, check battery statistics regularly in Settings → Battery, and limit the background activity of suspicious programs.
