Navigation applications installed on smartphones with operating system Android, allow users to build car, bicycle or walking routes, as well as monitor their own location on the map.
Mobile devices with installed GPS/GLONASS chips are in great demand among potential buyers. But, sometimes it happens that GPS on Android does not work. In this case, you should figure out what the main cause of the breakdown is and how to configure the modules so that they correctly fulfill the tasks assigned to them.
The main reasons for the failure of the GPS module
If GPS does not work on Android, you should check if the navigation module in the phone is disabled. This mistake is most often made by novice users who did not have time to fully understand the principles android work smartphones.
In order to cope with this problem, you should slide down the top curtain with your finger, which hides various shortcuts and notifications. Find the "Location" item in the proposed menu and activate it. When it becomes active, its color will change to green, bluish, and so on.
Activate GPS on Android to find your location After the “Location” item becomes active, you can start launching the navigation program.
It is worth noting the fact that developers take into account the interests of users, so many popular applications report disabling geodata.
An example is the Navitel application, which informs users that they do not have a GPS module connection.
It may be that the user activated geolocation in the smartphone settings, installed all the necessary navigation applications, but there were no positive results.
In this case, the reason may be hiding in banal impatience. When starting GPS/GLONASS modules for the first time, you should wait at least 15 minutes. During this time, the smartphone will be able to process information about which satellites are active in the area. Other launches of the navigation program will be much faster.
A similar problem can also arise if you arrive in another city or country with your phone turned off and decide to use geolocation. You should wait 10-15 minutes for a smartphone running on Android to be able to calculate its location. This behavior is called a “cold start”.
So, the main reasons why GPS does not work on Android are listed above. But they do not limit the list of all possible faults. It should be noted a few more factors, in connection with which there may be no operability of GPS modules:
- The user tries to perform a “cold start” while driving vehicle. You shouldn't do that. You need to stop, get out of the car, preferably in the most open area, and try again to activate the GPS modules.
- GPS does not work on Android, not only while traveling in a car, but also inside buildings.
- There are certain areas where signal reception is difficult. This may be due to the presence of rocks in the immediate vicinity, tall buildings etc. In this case, you should find the highest possible area and try to find satellites by climbing on it.
If the navigation does not work after active attempts to configure it, then you need to seek help from professionals working in the service center. This state of affairs clearly indicates the presence of internal breakdowns. And yet, if you go to specialists in service center no time, then try resetting your phone to factory settings.
You can check the quality of satellite reception using the GPS Test application from Chartcross Limited. If the GPS chip is working and geolocation is enabled, then a sky map will appear on the screen indicating the locations of active satellites.
How to set up the GPS module on a smartphone?
Many users are interested in how to configure GPS modules on Andrid. There are no specific settings in this case. But, if you wish, you can experiment a little using standard detection methods. There are the following factors in the operation of location detection:
- High accuracy. With this setting, location discovery occurs using all possible wireless modules. It uses not only GPS / Glonass, but also Wi-Fi, telephone network.
- Economy mode. The location is searched using mobile networks and Wi-Fi module.
- Only GPS modules. As the name implies, the search for a place occurs only with the help of satellites.
In order to specify the method used to detect the position of a person in space, go to the menu ”Settings-Geodata”. Don't forget to work with GPS navigation install functional and easy-to-use software. To do this, you can download from the network free apps or use the paid products of the world's leading companies.
Output
In conclusion, it is worth noting that if GPS does not work on Android, you should not despair. You may be in too much of a hurry to prevent the app from communicating with the satellites.
If the problem is not resolved after the basic conditions are met, you need to contact the service center for help.

In one of the articles, we considered the question of how to make a TV remote control from a smartphone.
It is difficult to find a smartphone that is not equipped with a GPS module. Even the most budget gadgets have this useful tool for navigation. It doesn't matter what model your smartphone is if you need to get directions or find out the location in an unfamiliar place. To enable GPS on your smartphone special knowledge no need - I pressed the right button and it all worked. But not everyone knows how to set up GPS on Android so that the smartphone does not overload the battery.
Let's talk about the main stages of setting up GPS, and also recommend several applications for Android, with which you can check the operation of the GPS module.
Automatically GPS on the smartphone does not start. To enable and configure it, you need to dig a little in the settings. In each version of Android, the activation path looks a little different. We will look at the main stages of enabling and configuring GPS in a smartphone on Android 6.0 Marshmallow.
Stage 1: Turn on
To turn on GPS, slide the notification shade down and tap on the bar that displays the time, date, and battery charge. You need to click on the gear icon, after which you will be taken to the Settings. In addition, you can get into the settings through the corresponding button in the general menu. We find the section Personal data and click on the Location button. At the top of the screen there will be a switch that activates the GPS.
Stage 2: Setup
By default, the location of the smartphone is determined by all sources. Uses GPS data, Wi-Fi, Bluetooth and mobile networks to exact definition locations with an accuracy of 10-15 meters. This function provides high reliability of geolocation, however, it should be noted that this mode heavily loads the smartphone battery. Therefore, in the settings you can choose one of two economical modes:
- By network coordinates
- By GPS satellites
The first mode uses only Wi-Fi, Bluetooth and mobile data. It is necessary that the smartphone is connected to the Internet via Wi-Fi, or the user needs to start Bluetooth mode. Without network connection the location of the smartphone is determined by the signal of the base station.
If there is no access to the Internet, and the nearest radio tower is several tens of kilometers away, then you should enable geolocation using GPS satellites.
After the GPS on the smartphone is turned on and configured, you can safely install the navigator application for Android. The most convenient and functional navigator you can choose, .
To check how GPS works on a smartphone, you can download special application in the shop Google Play. We will look at three programs available for free download. For their full-fledged work, you need to go outside.

Mobile devices and tablets are characterized by incredible ease of use and the widest functionality, allowing them to replace many other devices with a narrower specialization. Due to the presence of a GPS module, the gadget is able to communicate with special satellites, thanks to which, it becomes possible definition location of the device, as well as navigation on maps.
Problems with GPS
Quite often you can encounter a situation where gps does not catch on android. This greatly limits the functionality of the smartphone or tablet and makes it less convenient to use.
Since there are two GPS connection technologies, it is useful to understand their differences. The classic version involves establishing a connection with satellites, with the help of which the coordinates of the device are determined. A GPS involves, in addition to connecting to satellites, also connecting to cell towers, which allows you to determine the user's location more accurately.
Despite all the differences, both of these technologies are characterized by the same reasons that prevent them from working correctly. These include:
- Incorrect connection setup;
- The GPS module is defective;
- Surrounding objects are interfering with the connection or the user is indoors.
The last point is especially important, since novice users quite often forget about the features of a satellite connection, which certainly requires the absence of obstacles in the signal path.
Troubleshooting
Before checking the functionality of the module, it is recommended to check whether it is enabled at all on the device. Some users who are not familiar with the features of the operation of android smartphones quite often turn off the module itself or receive geo-data, which makes it impossible to establish a connection between the satellite and the gadget. Some applications remind you of disabled features, which allows you to quickly restore normal GPS operation.
IMPORTANT! If the module has lost its functionality, then the most reasonable option is to contact the service center, since it is not possible to fix such a malfunction on your own.
In some cases, if the connection settings are not configured correctly, you can solve the problem by . The same applies to situations when, after any changes in the settings, the device module has lost its functionality.
Some owners of Android smartphones often face the problem that the GPS module cannot catch or catches GPS navigation satellites for a very long time. This mainly happens with phones that were brought from China or bought from Chinese sites such as Aliexpress and they were not fully configured for Russian conditions.
The first thing we should do is go to the smartphone settings and go to the tab My location. Turn on the GPS and check the boxes against, By GPS satellites And By network coordinates. If you have more advanced settings, such as EPO Options then put a tick in front of the item, go down to the bottom and press the button download.
Next, we need to go to the engineering menuhow to do this, you can learn from the article "Engineering android menu". In the engineering menu, we pass location- Location Based Service - EPO and put on against parameters Enable EPO And Auto Download checkboxes, if you do not have these parameters, then they are by default and hidden from your eyes.
We return to location and go to section YGPS and on the tab INFORMATION successively press the buttons fuii-warm-hot-cold And AGPS restart this is done to reset the old almanac, and in order for us to record a new almanac, go to the tab NMEALOG and press start to record a new almanac.
Go to tab SATELLITES and see that we have several red satellites on the radar. After some time from 5 to 30 minutes, some of the satellites should turn green, and signal strength bars will appear below, which means that your phone has established a connection with these satellites. You need to catch satellites on the street and preferably away from houses, since the signal is extinguished indoors and it is almost impossible to catch them.
If, after the time has elapsed, the connection with the satellites has not been established, then the problem lies deeper and in order to fix it, you will need root rights on your smartphone. How to get a root we read the rights in the article "Opening root rights in Android". The rights root we need to edit the file GPS.conf. So using a file manager that works with root(I used Root Browser) go to the root directory of the phone and look for the file at the following address system-etc-gps.conf. Open the file with a text editor gps.conf and we look at what is there, this file stores the addresses of the satellite servers, and for some reason it turned out to be empty for me. If you also have an empty one or have some addresses of other countries, then we change the contents of the file to the settings we need, save, close and restart our smartphone.

Many owners of phones on the Android operating system are faced with a problem when the built-in GPS module refuses to find gps satellites or finds them, but cannot connect. There may be several reasons for this behavior of the module, consider the main ones:
Incorrectly specified parameters for connecting to satellites in the settings file;
An A-GPS module is installed, which often does not find satellites on the phone on its own;
The module is not working.
I would like to sort out the problem with the A-GPS (Assisted GPS) module, since Chinese phones, on which it is installed in 98% of cases, are now very popular and are ousting global brands from the market.
How does A-GPS work?
The main difference from the standard GPS module is that it connects not only to satellites, but also to the towers of mobile operators, which significantly improves the quality of location determination. When this function is enabled, the phone often cannot connect to GPS satellites and it needs a "Full Restart" even if it was only enabled. This is not a problem of the Chinese phones themselves, but of the A-GPS module, which costs a penny compared to GPS, and therefore works accordingly. Let's figure out how to set up gps on android.
How to determine if A-GPS or GPS module is on the phone?
If you have a phone with two SIM cards and made in China, you have A-GPS with a probability of 99.9%. But to verify this, you can go to engineering menu. The fix for the issue of a broken connection with satellites will begin with it.
To enter the engineering menu, you need to dial the following number on your phone: *#*#3646633*#*#. If the combination did not work, you can try to enter *#15963#* or *#*#4636#*#*, however, in this case, your menu may be different.
After entering the phrase, you will automatically enter the engineering menu and see the following window:
You need to move to the left, scrolling through the settings pages to the "Location" tab.
Now select the first item "Location Based Servise". If you have an A-GPS tab, then follow the next settings. Otherwise, this article will not help you much.
Setting up GPS on Android
If you have an A-GPS tab, go to it right away. You should have a window like this:
Compare the settings with yours, adjust if necessary, according to the screenshots:
If everything is spelled out correctly, you can go back one level before selecting the "Location" items and go to "YGPS".
Here you see that your gps module does not find satellites, or rather finds, but does not connect due to incorrect inclusion:
You need the "Information" tab. It will carry out the main manipulations.
As you can see, the status is "UNANVAILABLE", and TTFF hangs on an eternal search. No matter how long you wait, nothing will change.
The essence of fixing the eternal search is to do a full reset "Full", and then, after 2-3 seconds, click on "A-GPS Restart". Those. you reset the hung search process to zero, thereby overwriting all predefined settings, and immediately reload the module. Not having time to pick up the standard configuration (incorrect), the module with clean slate finds all satellites.
After 10-20 seconds, on the “Satellites” tab, you will see satellite signals, and after another half a minute, the module will successfully connect to them.
The search was done from the 1st side of the house, on the balcony, respectively, nothing was found on the second hemisphere. On the road you will find all the satellites.
Navigation applications installed on smartphones with the Android operating system allow users to create car, bicycle or walking routes, as well as monitor their own location on the map.
Mobile devices with installed GPS/GLONASS chips are in great demand among potential buyers. But, sometimes it happens that GPS on Android does not work. In this case, you should figure out what the main cause of the breakdown is and how to configure the modules so that they correctly fulfill the tasks assigned to them.
The main reasons for the failure of the GPS module
If GPS does not work on Android, you should check if the navigation module in the phone is disabled. This mistake is most often made by novice users who did not have time to fully understand the principles of operation of Android smartphones.
In order to cope with this problem, you should slide down the top curtain with your finger, which hides various shortcuts and notifications. Find the "Location" item in the proposed menu and activate it. When it becomes active, its color will change to green, bluish, and so on.
Activate GPS on Android to find your location
After the “Location” item becomes active, you can start launching the navigation program itself.
It is worth noting the fact that developers take into account the interests of users, so many popular applications report disabling geodata.
An example is the Navitel application, which informs users that they do not have a GPS module connection.
It may be that the user activated geolocation in the smartphone settings, installed all the necessary navigation applications, but there were no positive results.
In this case, the reason may be hiding in banal impatience. When starting GPS/GLONASS modules for the first time, you should wait at least 15 minutes. During this time, the smartphone will be able to process information about which satellites are active in the area. Other launches of the navigation program will be much faster.
A similar problem can also arise if you arrive in another city or country with your phone turned off and decide to use geolocation. You should wait 10-15 minutes for a smartphone running on Android to be able to calculate its location. This behavior is called a “cold start”.
So, the main reasons why GPS does not work on Android are listed above. But they do not limit the list of all possible faults. It should be noted a few more factors, in connection with which there may be no operability of GPS modules:
- The user tries to perform a “cold start” while the vehicle is moving. You shouldn't do that. You need to stop, get out of the car, preferably in the most open area, and try again to activate the GPS modules.
- GPS does not work on Android, not only while traveling in a car, but also inside buildings.
- There are certain areas where signal reception is difficult. This may be due to the presence in the immediate vicinity of rocks, tall buildings, and so on. In this case, you should find the highest possible area and try to find satellites by climbing on it.
If the navigation does not work after active attempts to configure it, then you need to seek help from professionals working in the service center. This state of affairs clearly indicates the presence of internal breakdowns. And yet, if there is no time to go to the specialists at the service center, then try resetting the phone to factory settings.
You can check the quality of satellite reception using the GPS Test application from Chartcross Limited. If the GPS chip is working and geolocation is enabled, then a sky map will appear on the screen indicating the locations of active satellites.

Output
In conclusion, it is worth noting that if GPS does not work on Android, you should not despair. You may be in too much of a hurry to prevent the app from communicating with the satellites.
If the problem is not resolved after the basic conditions are met, you need to contact the service center for help.
Modern gadgets are already so sophisticated that you can determine your location without resorting to the help of GPS navigators anymore. Sometimes this is necessary for the correct operation of applications, sometimes it is necessary to create the correct route. When GPS does not work on Android, this becomes difficult. What could be the reason for this and what should be done to solve this problem?
Any device does not catch well or does not catch a satellite signal at all if it is indoors. Therefore, it is better to engage in determining your location on the street. Ideally, the space should be free even from tall buildings and trees so that the sky is completely open, so that nothing prevents the gadget from searching for a working signal and connecting to the necessary satellites.
Wrong GPS setting
All devices are endowed with two GPS modules. One is a standard receiver that can be enabled in the settings (General - Location - Mode). When choosing mobile networks or wifi device will determine the location by the towers without connecting to GPS satellites. This method is the fastest, but it does not always give an accurate result.
When you select GPS Only mode, your phone or tablet will connect to the satellites, but the device will take some time to do so. At the same time, it is desirable to be on the street on open area or at least put the gadget on the windowsill. It is for the operation of the second module that the correct configuration is needed. How to check if the device is receiving a signal? To do this, you will have to download and install GPS Test - a diagnostic application.
After starting the program, in the AGPS settings, select Update only, and in Settings - Keep Screen On. Now you need to return to the main program window, the GPS test will begin on your tablet or phone. It is important, however, that Wi-Fi and mobile data should neither be enabled in the Location settings nor be in use at the moment.
If the diagnostics showed that the device does not find satellites, then you should check whether the GPS settings on Android have been correctly configured. How to set up GPS? To do this, you must first download any application that can process the GPS signal. If it does not help, you need to check the settings of the communicator's COM port.
Unsuccessful flashing
After not the most successful attempts to flash a gadget or a specific GPS module, not only the system, but simply its individual parts, for example, geolocation, may stop functioning. It is also common to see GPS stop working on a Chinese device.
To fix this situation, you need to enable AGPS in the location and GPS settings. After that, you need to enter the engineering menu through the dialing window (the combination is different for all phones). If you can’t enter it, you will have to use any special program, but already with root rights. Procedure in:
- on the Satellites tab of the YGPS tab, check if there is a signal, i.e. whether the phone or tablet is trying to find satellites at all;
- go to the Information tab and there, in order, press the buttons full, warm, hot, cold (this is necessary to reset the previous settings);
- on the NMEA Log tab, click start;
It often happens that changing the firmware on the device, or buying a new one Chinese phone(sometimes not Chinese), we are faced with the fact that the smartphone does not work GPS . It also happens that GPS does not determine the location for a long time. Why is this happening?
This is due to the fact that the phone often comes to us from the other hemisphere of the planet. And he has an Almanac that is irrelevant for our area.
If your GPS is buggy, we will try to fix it.
So, I will show you how to treat GPS:
GPS + AGPS method (ROOT needed):
1) Must be included in android settings, in the “My Location” section of AGPS, then opening the top “curtain” on your phone to activate GPS.
2) Then in the dialer, you need to dial * # * # 3646633 # * # * - this is the entrance to the engineering menu.
Maybe another number will work on your phone to enter the Android engineering menu:
*#*#4636#*#*
*#*#8255#*#*, *#*#4636#*#* - for Samsung
*#*#3424#*#*, *#*#4636#*#*, *#*#8255#*#* - for HTC
*#*#7378423#*#* - for Sony
*#*#3646633#*#* - for Philips, Fly, Alcatel
*#*#2846579#*#* - for Huawei
If it doesn't work, look for information on how to enter the engineering menu on your Android phone. If you have a phone based on MTK processors (MT 6577, MT 6589 ...), you can use the “Mobileuncle Tools” program ( ROOT is required), it can be downloaded from Google Play. It has a section Engineer Mode. He is what we need.
3) When you got (by any means) to the engineering menu of the phone, you need to go to the YGPS tab - and look at the "Satellites" tab - if the signal scales appear. If yes, then the phone tries to search for satellites, but does not find it due to an incorrectly recorded Almanac. And this is not surprising, because the device came from the other “end of the world”.
4) The next step is to go to the “Information” tab, and then press the “full”, “warm”, “hot”, “cold” buttons in turn (for full reset old Almanac).
5) After that, on the NMEA Log tab, you must click start button. (recording of the new Almanac will start)
6) Now for correct operation GPS, you need to go to the back of the “Satellites” and wait for 5-15 minutes until the maximum number of satellite scales is found (usually from 10 to 13 pieces) and their scales turn green.
7) When all satellites are found, go back to the Nmea Log tab and press the “stop” button. Congratulations, a new almanac for your area has been recorded.
I did this procedure on many Chinese phones - as a result of the procedure, the phone should start finding satellites faster.
Let me remind you that all the above actions to improve the quality of GPS must be carried out purely in open areas, away from buildings. And the last piece of advice - I recommend setting the exact system time and date in the phone.
Method GPS + EPO (need ROOT):
1) With help file manager that supports Root and root access, you need to delete the following files: /data/misc/EPO.dat /data/misc/mtkgps.dat , /system/etc/gps.conf
2)
You need to go to "settings - location data" and turn on the GPS.
Then you need to enable EPO and download (i.e. you need to re-download - after deleting EPO.dat)
3) Make sure A-GPS is turned off. (this is mandatory!) [and cannot be turned on after, otherwise it will stop working normally]
4) Turn off the phone, pull out the battery, insert the battery, turn on the phone.
5) go to the engineering menu (see above for ways to enter) - go to the location tab - there will be 2 sub-items (location based service and YGPS)
6)
We go outside to an open area where GPS is caught as well as possible, and go to the YGPS sub-item (we don’t press any buttons!), Within 3-10 minutes we wait for the correction (it takes a long time to wait).
As soon as the correction is completed, exit the YGPS section with the back button, then enter the YGPS section again. Attention is now the most important part:
When you start GPS 2, red dots (satellites) should appear, but not all at once at the same time, but every 2 seconds 1-3 pieces should appear. For instance:
At the beginning 2 - then 5 - then 7 - and at the end 10 red dots on the radar.
If the dots appear gradually, then the EPO is configured correctly.
But if they all appear at the same time - EPO does not work
7) We check the operation of GPS in navigation programs.
The geolocation feature in Android devices is one of the most used and in demand, and therefore it is doubly frustrating when this option suddenly stops working. Therefore, in our today's material, we want to talk about methods of dealing with this problem.
Why GPS stops working and how to deal with it
Like many other problems with communication modules, GPS problems can be caused by both hardware and software causes. As practice shows, the latter are much more common. Hardware reasons include:
- module of poor quality;
- metal or just a thick case that shields the signal;
- poor reception in a particular place;
- manufacturing defects.
Software causes of problems with geolocation:
- change of location with GPS turned off;
- incorrect data in the gps.conf system file;
- outdated version of GPS software.
Now let's move on to troubleshooting methods.
Method 1: Cold Start GPS
One of the most common causes failures in the operation of the GPS - transition to another coverage area with data transmission turned off. For example, you went to another country, but the GPS was not turned on. The navigation module did not receive a data update in time, so it will need to re-establish communication with the satellites. This is called " cold start". It is done very simply.
1. Get out of the room to a relatively free space. If you are using a case, we recommend removing it.
2. Turn on GPS reception on your device. Go to " Settings».
On Android up to 5.1 - select the option " Geodata"(other options -" GPS», « Location" or " Geopositioning”), which is located in the network connections block.
In Android 6.0-7.1.2 - scroll the list of settings to the block " Personal data» and tap on « Locations».
On devices with Android 8.0-8.1, go to " Security and location", go there and select the option " Location».
3. In the geodata settings block, in the upper right corner, there is an enable slider. Move it to the right.
4. GPS will be enabled on the device. All you need to do next is to wait 15-20 minutes for the device to adjust to the position of the satellites in this area.
As a rule, after the specified time, the satellites will be taken into operation, and navigation on your device will work correctly.
Method 2: Manipulating the gps.conf file (root only)
The quality and stability of GPS signal reception in an Android device can be improved by editing the system file gps.conf.
