Navigation modules in currently manufactured Android smartphones are built in at the production assembly stage. As a rule, these useful additional devices not bad. Just turn on GPS using the settings menu and launch the downloaded “maps” application. In a couple of minutes the device will determine its location.

With GPS always on, determining coordinates will not take even one minute. However, sometimes this function does not work in android gadget. Most often, the problem lies in incorrect or completely absent GPS settings.

Required additional services

They are without special problems run on an Android phone:

1. a-gps (a service that additionally loads location data from the Internet, using the services mobile operators. The determination accuracy of this option is of course worse, but thanks to its operation, accurate satellite determination is accelerated);
2. wi-fi;
3. EPO (a service from Mediatek that pre-calculates the movement in the orbits of navigation satellites.

However, the pre-installed EPO data in phones is designed for Asian countries and may only work with glitches in Europe. During 2012-2014, Mediatek began producing chipsets with excellent characteristics, which currently use the brands Sony, LG, and HTC in their products. Thus, in Android smartphones with an MTK processor, there is a problem with navigation, which consists in the incorrect functioning of GPS).

The procedure for eliminating the causes of incorrect GPS operation in a phone or tablet

General settings

Ten years ago car GPS navigators were a curiosity at domestic market electronic devices. But today it is difficult to surprise anyone with the presence of built-in global positioning systems in modern smartphones and tablets.

General information about GPS

Majority modern smartphones and tablets presented on the mobile device market today are equipped with a GPS module for determining location. This is a really convenient and advanced option. In addition to plotting a route for a car or bicycle on the ground, the GPS module will be able to determine its own location with high accuracy up to tens of meters. Along with this, the system makes it possible to turn on some programs or activate the reminder function on the phone when you are at a certain point globe. on Android?

The main disadvantage of GPS positioning

The main disadvantage of GPS positioning in a smartphone is the rapid drainage of the battery. In this regard important point the correct adjustment of the operating mode seems to be below. Below we will discuss the basic tools for how to set up GPS on Android, as well as the principles of working in the engineering menu of a smartphone in case of incorrect functioning of the system.

Enabling GPS operating mode

To enable GPS navigation, you can use the notification panel of your smartphone. The enabled positioning system is displayed at the top of the screen in the form of a periodically flickering circle. To change or view how GPS functions, you need to go to the smartphone settings, then to the “Personal Data” section, from there to “Location” and select “Mode”. Typically, the operating system provides three options to choose from, including “By device sensors,” “Battery saver,” and “High accuracy.” If we are talking about phones that use latest versions"Android", the menu may look slightly different. How to set up GPS on Android 5.1? In this case, the listed items will be named “By all sources”, “By network coordinates” and “By GPS satellites".

Highest level of GPS accuracy

The most accurate positioning option is the “High accuracy” or “Across all sources” mode. At the same time, with this operating procedure, battery consumption will be the most intense and rapid. In this mode, the system tries to determine the location by all means available to it, namely: GPS, Wi-Fi and using mobile networks. The smartphone will constantly evaluate the space for the presence of a signal and try to determine the location not only in open areas, but also indoors.

This operating procedure is also sometimes called A-GPS. His distinctive feature Compared to the work of conventional navigators, it is possible to obtain additional service information about satellites via an Internet connection. This speeds up the search for satellites and obtaining data on their signals.

Other modes of global positioning operation

Mode GPS operation"Battery saver" or "By network coordinates" is used to receive a signal exclusively wireless networks. At the same time GPS module not activated. Of course, in this mode the accuracy of position determination is somewhat deteriorated. At the same time, indoor position can be determined using Wi-Fi.

The operating mode “By device sensors” or “By GPS satellites” can only function in open areas without interference. IN in this case The position of the object is determined using satellites. If interference occurs in the form of high-rise buildings or walls and ceilings of premises, the satellite signal will be lost and the position will no longer be determined. It would be appropriate to say that this article is about how to set up GPS on Android without the Internet. But it should be noted that such installations are also possible using the World Wide Web. In this case, the Internet is used to correct the situation when there is insufficient good signal from satellites.

The last operating mode is the most economical for the battery. In addition, you can disable determining your own position on the ground in the notification panel. If you need to get a route from point A to point B, you can turn on positioning and follow the prompts of the navigator built into your smartphone. If you need a personalized search for an object, you should give preference to the "Battery Saver" mode. Well, if the phone has a powerful and capacious battery the user may well choose the most expensive method of operation, “High precision”. The methods described above are suitable for solving the problem of how to set up GPS on Android through the main menu of the device.

Configuration using the smartphone’s engineering menu

However, some smartphone models, especially those made in China based on MTK processors, may experience connection difficulties or unstable communication. There are even cases when the device does not determine the location of an object at all. This is due to incorrect configuration of the GPS module for operation in domestic latitudes.

This software malfunction you can level and set up GPS on Android via engineering menu mobile device. It should be emphasized that you can use this functionality on devices on which the mode is activated Root works, giving the user the opportunity to control the smartphone as developers.

Next, you should perform a series of sequential operations. First you need to turn on GPS and Wi-Fi and go outside or to the balcony of your room. After this, you will need to enter the engineering menu by entering the combinations on the phone keyboard: *#*#3646633*#*#, *#15963#* or *#*#4636#*#*. It should be noted that on different models On smartphones, the combination of symbols may be different, or even not suitable at all. Then, to solve the problem of how to set up GPS on Android, you can use the Mobileuncle ToolHero application, in which, after launching, select the desired item and enter the engineering menu.

Here the user will find several bookmarks, from which he must select Location, and then go to Location Based Service. In the EPO line, you must check the Enable EPO and Auto Download boxes. It should be clarified that EPO is system file, which contains information about the coordinates of GPS satellites and their lines of movement. This item is often deactivated on some phones.

Now you need to go back a step and select YGPS, and then go to the Satellites tab, in which the user will find a map of the position of the satellites in orbit. If satellites are displayed in red, this indicates that mobile device sees them, but cannot receive a signal from them due to incorrect settings.

To fix this problem, you need to go to the Information section, click full, and after a few seconds AGPS restart. After this, you need to return to Satellites and wait until the satellite icons light up green. It is best to carry out this operation in an open area, since on the balcony, due to significant interference in the form of house walls and trees, the signal quality is much worse. The last step is to reboot your device, be it a smartphone or tablet. Thus, the most common ways to set up GPS on Android are discussed.

Today I once again thought about the issue of poor GPS signal reception on my Chinese smartphone Jiayu G2. But, unexpectedly for me, the problem was solved in just a couple of minutes - the “Chinese” finds satellites within 20 seconds. Now let's talk about everything in order.

In October I received chinese phone, ordered on Aliexpress. The phone is excellent for the money, and everything would be perfect, but the GPS module found the satellites for a very, very long time, in about an hour, no faster. And this is with Wi-Fi turned on and A-GPS and GPS EPO assistance checked. This didn’t make me happy at all and I had to remember a useful post on the livejournal blog, the advice from which I used when setting up my first smartphone on Android. It came down to editing gps.conf auxiliary programs. This helped the “Chinese friend”, but after the first (and so far last) factory reset GPS settings The fishing began to get even worse - I left it in the open air for an hour to search for satellites and no results. And today I started looking again for that useful post on the livejournal blog and came across an update in the post header:

"Fantastic!" I thought and immediately followed the link. Compared to the first post, this time even more specific actions were proposed, namely replacing the contents of the file gps.conf(you can find it along the way /etc/gps.conf, must be root-rights) to the following settings:

NTP_SERVER=ua.pool.ntp.org

These settings are designed for residents of Ukraine, but for residents of Russia they are very easy to adapt by replacing ua.pool on ru.pool.

On my own behalf, I can add that I use the GPS Status application, and after rebooting when I first launched the application, I reset the cache data: in the program, call up the menu, then select Tools, there Manage A-GPS state and click Reset and then Download.

I take my hat off to the author of the original post, dear mechanicuss. His advice helped not only me, and can help many more sufferers.

That's all. Everyone clear skies and a stable signal from space.

Availability GPS navigator and in Android smartphones or tablets will surprise no one. GPS navigator on mobile platforms Ondo also has an advantage - it can work without connecting to a satellite, but only by working with mobile towers, but in this case you can only get location coordinates. For global definition your location will have to connect to satellites, as was the case with classic portable GPS.

GPS does not work on Android

In fact, there can be a lot of reasons why GPS does not work on Android, so we immediately rule out hardware failures (technical problems), only a service center will help here.

• Not correct setting GPS. This happens most often. can be read here. You can test the correct GPS settings using the application GPS Test
• GPS does not work after flashing. In this case, the GPS settings are lost. How to return the settings - read the article at the link above, the article will contain a video in which everything is described in detail.
• The initial connection to satellites has not been made. In remote areas this process may take long time up to an hour. But to do this, you need to put your phone or tablet outside or on a windowsill. After binding, GPS will work faster.
• Android GPS does not work indoors. More precisely, it can work, but rather weakly. For correct operation The GPS module must be outdoors and visible to the sky.
• Hardware problems. If, after all the manipulations with the GPS settings, the module still shows no signs of life, then you should contact specialists at the service center.

Android phones contain a GPS module that allows a large number applications to determine location and navigate the terrain. The functionality of a phone with GPS is greater than that of a standard external portable GPS. But they still need to be able to use it correctly, so that there are no questions about why GPS does not work on Android.

How GPS works on a phone

A little about how GPS works in a smartphone, so that you can understand what settings to set.

• Android apps can find location using mobile network towers.

If you go to location settings Android phone, you will see two definition options to choose from. One definition is called a network position. This option calculates coordinates using towers mobile communications or via Wi-Fi. The advantages of this method include fast speed work, and the downside is that it is not an accurate indication of the location. A slower way is satellite GPS navigation.

• Android phones and tablets use Assisted GPS (aGPS).

This technology allows you to find out the satellite position using the network and at the same time receiving data much faster.

• Android GPS can work without a mobile connection.

You can hear from managers of various mobile networks that GPS does not work on Android if it is not in the area of ​​​​mobile towers. Maybe, but this requires the correct setting of the satellite navigation.

• When first determining a position (first fix) in areas that are too remote, it takes time.

This process can take from ten seconds to an hour in different places. The first time always takes longer, but with subsequent connections everything will go much faster

• Cards matter when Android works GPS.

If you open Google Maps, without network connection, then the smartphone will display the error “This application requires active tariff plan" This also happens with other applications; if the application uses Internet maps, then a constant connection to the network is required.

• Android GPS should be able to see the sky clearly.

Few people know this rule. But those who have worked with portable GPS are well aware of this. Why doesn't GPS work? This is because these positions are transmitted from satellites, which means that the transmission quality will be better if the signal is not interfered with by the floor slabs of houses or meter-thick layers of earth in the subway.

• Android GPS drains your tablet or smartphone's battery.

Everything is simple here. Want to extend the battery life of your smartphone? Then turn off the GPS module. This also applies to other modules. Of course, no one can tell you exactly how long the operating time will last after switching off, but in any case it will not be superfluous if you do not use GPS too often.

These are the basic principles regarding the issue of how GPS works in a smartphone and tablet.

On modern devices GPS and GLONASS sensors are installed for mobile communications. On devices with operating system Android, in particular, this makes it possible to always determine your location and draw routes using maps on your phone, without using paper analogues. This is especially true for navigators installed in the car. But what to do if GPS does not function on Android? First of all, we will find out the reasons, and then we will try to correct the situation.

Reasons for GPS not working on Android devices

The simplest and most easily remedied reason that GPS does not work is an inactive navigation module. If your smartphone has not been set to operate the navigation module by default, you need to do it manually. Beginners may not figure out this reason until they open the settings. You need to sweep down and in the menu that opens, next to the clock and notification shortcuts, switch “Geolocation” to active mode.

After activation, navigators in applications will work as standard. In many applications with a navigator, the user is notified if the module is not active. Applications for creating routes on phone maps automatically redirect the user to the menu after activating the module before starting work.

If you have activated the module and turned everything on, but the GPS does not respond to your actions, you just need to wait up to 15 minutes until the data is loaded, it does not work in lightning mode. Satellite visibility and download speed depend on many factors, from weather to stability mobile signal from the tower. After the first download, the data will be installed and will be opened quickly in the future.

You also need time to recognize a new place when you arrive with your device in another region or country. The smartphone first determines its location and then operates quickly in this environment.

Other reasons why GPS may not work when first started:

• You are trying to start the navigator while driving - stop the car and allow the device to boot in a calm and stable position;
• You are in a place where there is no connection - GPS does not turn on indoors, unlike the Internet;
• You launch the navigator in an area with natural interference for the satellite - mountains, vegetation, buildings.

After you have found one of the listed reasons and fixed the problem, the navigator on Android will work. If this does not happen - you have problems with the device - contact the service center to set up the software.

If your GPS worked and then stopped, this indicates an internal failure of the device. Before sending it to the service center, try to fix it yourself, namely, reset the settings to the factory level, perhaps you have been tricky with the settings and confused the device.

Using the Chartcross ltd program you can do a GPS Test to check the satellite coverage area in your area. When the module is working properly on the device and there is no interference with the signal, you will see on the application screen a map of the sky above you with dots that indicate the location of the nearest satellites.

How to make GPS settings on Android

There is no need to make any special settings, everything works automatically. If you want to customize something, you can change the way the signal is detected:

• The signal will be highly accurate if you use all reception points - the GPS module on the phone, Internet Wi-Fi and satellite;
• Energy saving is a mode when using telephone networks and Internet Wi-Fi;
• GPS only - satellites will work.

You need to go to the settings in the “Geodata” section, where you need to check the box. The navigator will work using a special program. There are applications for smartphones, for example, Maps.me. Its functionality also includes convenient maps that can be used offline; its use is free.
