Navigation modules in the smartphones manufactured to today, are embedded at the production assembly stage. As a rule, these useful additional devices are not bad. It is enough to enable GPS using the settings menu and run the download "Map" download. After a couple of minutes, the device will determine the location.

With permanent GPS, the determination of the coordinate will not take one minute. However, sometimes this feature does not work in the Android gadget. Most often, the problem is incorrect or in the missing GPS settings.

They are launched without any problems in the phone on Android:

a-GPS (service loading additional location data from the Internet, which uses the services of cellular operators. The accuracy of determining this option is of course worse, but due to its functioning there is an accurate satellite definition);
wi-Fi;
EPO (service from MediaTek, calculating the navigation satellite orbits in advance.

However, the pre-installed EPO data in phones are designed for Asian countries and in Europe can only work with failures. During 2012-2014, MediaTek began producing chipsets with excellent characteristics, which are now used in their goods Sony, LG, HTC brands. Thus, in smartphones on android with the MTC processor, there is a problem with navigation, which is improperly functioning GPS).

Modern gadgets are already so fed that it is possible to determine their location, no longer resorting to the help of GPS navigators. Sometimes it is necessary for the correct application of applications, sometimes - to create a right route. When GPS does not work on Android, it becomes difficult. What can it be connected with and what to do to solve this problem?

Any device does not catch or catch a satellite signal at all if it is indoors. Therefore, it is better to deal with the definition of your location on the street. Ideally, the space should be free even from high buildings and trees, so that the sky is fully open, so that nothing hovers the gadget to search for a working signal and connect to the desired satellites.

Incorrect setup GPS.

All devices are endowed with two GPS modules. One is a standard receiver that can be enabled in the settings (General - location - mode). When you select mobile networks or Wi-Fi, the device will determine the location by tower, without checking the GPS satellites. This method is the fastest, but does not always give an accurate result.

When the "GPS only" mode is selected, the phone or tablet connects to satellites, but for this device will need some time. At the same time, it is preferably located on the street in an open area or at least put a gadget on the windowsill. It is for the operation of the second module and the correct setting is needed. How to check if the device catch a signal? To do this, you will have to download and install GPS Test - the application for diagnostics.

After starting the program in the AGPS settings, select Update Only, and settings - Keep Screen ON. Now you need to return to the main window of the program, the GPS test will begin on the tablet or phone. At the same time, it is important that Wi-Fi and mobile data should not be included in the location settings, or at the moment.

If the diagnostics showed that the device does not find satellites, then check whether the GPS is set correctly on Android. How to set up GPS? To do this, you first need to download any application that can process the GPS signal. If it does not help, you need to check the COM port settings of the communicator.

Unsuccessful flashing

After not the most successful attempts to flash the gadget or specifically the GPS module can stop functioning not only the system, but also simply separate parts, for example, geolocation. Also often observed stopping GPS on the Chinese device.

To correct this situation, you need to include AGPS in the location settings and GPS. After that, you need to enter the engineering menu through the dialing window (for all phones the combination is different). If you do not work, you will have to take advantage of any special program, but already with ROOT rights. Procedure in the engineering menu Android:

on the Satellites tab of the YGPS tab, whether there is a signal, i.e. Is the phone or tablet find satellites at all?
go to the INFORMATION tab and there in order Press the Full, Warm, Hot, Cold buttons (this is necessary to reset the previous settings);
on the NMEA Log tab, click Start;
return to the Satellites tab and wait from 5 to 15 minutes until the device finds the maximum number of satellites, and the GPS signal scales will not be green;
back to the NMEA Log tab, click Stop.

This method is described in more detail in the video.

Primary binding and calibration

It happens that the device is in some distant terrain. In this case, it is advisable for a long time to put it in the open area and wait until the search and binding passes.
Sometimes navigation can stop working because the compass calibration is incorrect. Such a phone or tablet will be incorrectly oriented, as a result, a problem with GPS on the device appears. For calibration you need to download a special application, GPS Essentials. After installing and starting it:

Press the compass icon.
Select a smooth smooth surface, put your device on it and remove all electrical appliances from it.
To smoothly turn the device around each axis 3 times.

After that, you need to try to connect and, if necessary, repeat calibration.

Problems with the device itself

If the gadget, proven and configured in accordance with all the rules, still does not catch satellites, check the GPS settings and find the cause will help you only in the service center. It may so be that the problem is lurking in the device itself.

Read everything about how to enable GPS on android, configure and check performance. As well as ways to solve problems, if GPS does not work. In almost every modern telephone you can find the GPS navigation system. It is used in applications to search for addresses, call taxi and online order delivery. And these are only small features opening with satellite navigation. If you want to use all the available smartphone options, the use of GPS for android is be sure.

How to enable GPS on Android location?

If you want to use all navigation capabilities, you first need to activate the module. It is easiest to do this if the "Location" option is put on a curtain, descending from the top of the swipe screen. Then you just click on the icon to activate the satellite search.

Tell how to enable GPS on android:

Go to the Main Menu of the smartphone where all applications are collected. Select the "Settings" icon and click on it.
From the list, select "Location".
Go to the "Mode" section. From the proposed options, note "for all sources."

If you have enough approximate determination of the coordinates, you can choose from GPS satellites. In some models of smartphones, the "Location" utility is replaced by "geodata". Please note that the lever next to this function is in an active condition (it has been highlighted by color).

General Navigation Settings on Android

We already casually mentioned about different navigation modes. Now it is worth staying on them. Read more:

High accuracy mode ("For all sources") is implemented using the A -GPS module. This option can be found only in modern smartphones. When this mode is selected, the space will continuously monitor the presence of a signal. Navigation equally works well in the room and in the open space. The phone in this mode quickly communicates with satellites.
"Battery savings" does not use GPS -module. In this case, you lose accuracy, since in the room the location is determined by the Wi -fi signal, and outside it by cellular tower.
"According to the device sensors" - in this case, geolocation will only work in the open area, since the module will only receive a signal from the satellite. This is an accurate, but very uncomfortable. Now they are practically not used.

If you do not need to navigate in the forest or measure physical activity, it is enough to choose the battery saving mode. You will receive an acceptable result that is enough for most applications. For applications that need high accuracy, you can temporarily include high accuracy mode. Remember that in it the battery power consumption is excessively high.

How to check and configure GPS in a smartphone

If you are not satisfied with the quality of the coordinate definition or the receiver does not work at all, then it is necessary to check and configure the module. To do this, turn on the location module first, and then apply additional features.

Use GPS Test

One of the most accessible methods of debugging are special utilities. All actions in them occur in automatic mode. One of the best programs is GPS Test. Tell how to check the GPS on android with its help.

Open the application and look at the status bar from above. If it is indicated 3D FIX, then the module works fine. When the NO Fix is \u200b\u200binscriptions, the module is required, the location definition does not occur. A constant change of states occurs with a bad signal from the satellite or finding indoors.
If in the status bar value OFF, then you did not turn on the receiver.

Configure the receiver's work using this program cannot be. It only records the data obtained. The utility allows you to find out:

accurate location coordinates;
the number of visible satellites and information about them;
gives data on time zone at the location of the subscriber, height above sea level at this point, sunrise time and sunset.

This application can be used as an electronic compass. In a pair with a navigation module, it will allow you to navigate in the open area. With the GPS Test and the setup partition, you can enable the module if it failed to make the standard way. Activate all methods for producing coordinates for high geopositional accuracy.

We use the engineering menu

You can use at your own risk. If you are an inexperienced user or very much worth your device, it is better not to call the settings. Previously need to get a root for your smartphone. Then the problem, how to configure GPS for Android, is solved as follows:

Activate GPS and WI -FI, go to the balcony or sit on the windowsill of the open window. The best option for configuring through the engineering menu is the placement of the user on the open area, on the street.
Call the engineering menu of one of the commands * # * # 3646633 # *, or * # * # 4636 # * # *. If the listed combinations did not come up, you can choose the appropriate using the MobileUncle Toolhero utility.
Please note that the engineering menu is written in English. Therefore, it will be difficult with him to cope with those who do not know this language. In the window that opens, you will see several sections. Scroll to the left before the location option, go down to the Location Based Service.
Go to the EPO tab, you need to put markers in front of ENABLE EPO and Auto Download items. If the EPO path is not active in your device, you need to download the same file to the device so that information about the flight path and satellite location appears.
Return with the arrow back. Select YGPS and open the Satellites tab. You will see the satellite location scheme, they will be inactive and highlighted in red. The device sees them, but cannot be connected.
Go to the INFORMATION section and click on the word FULL. After 2 seconds, activate AGPS Restart.
Return to the Satellites tab, your device will connect to satellites and points change the color to green. If you are at the window or on the balcony, the color change will not happen to all satellites.
Restart the device so that the signal becomes more confident.

On this, the GPS setting to the Android approached the end, after the manipulations carried out, the module should work normally.

What if the GPS does not work?

If the manipulations produced did not help, and you still could not turn on geopositional, then it is necessary to find the cause of the failure and eliminate it. First, check the standard settings, test the device using utilities and engineering menu.

Causes of failures

If the GPS does not work on android, then the reasons can be:

Hardware faults - the module failed due to the mechanical impact on the smartphone body or fluid from entering its main fee. In rare cases, the hardware failure occurs against the background of low-quality components.
Software failures - damage to the module driver on the background of infection with viruses, problems occur when updating the device for or firmware.

First you need to understand why the module does not work. After you set the cause of the breakdown, you can enjoy it.

Solution of problems

If you cannot enable "location", then first you need to check the module settings and restart the device. Often the problem occurs when the operational memory is overloaded, which leads to a lack of it for the module. Try changing the mode of operation of the module for the "Mobile Network" option. If after that geolocation earned, then the problem with the driver or in the hardware. The inability to change the mode of use of the device occurs when flashing when flashing.

If the module fails after changing the firmware, you must restore the factory version of the operating system. To do this, press the volume and turning keys at the same time. After 5-7 seconds, Recovery mode appears on the screen. From its menu, select Confirm your Solution Solution Solution. Then you need to select the Reboot System Now item, and wait for the device.

You can calibrate the module after a failure using the ESSENTIAL SETUP utility. It applies for free through the official application store. Place your smartphone on a flat surface, open the application and press the TEST button. Manipulations are made automatically.

If all the procedures did not help, you can not solve the problem. In this case, contact the service center to replace the module. Now you know everything about setting up and working GPS -module on smartphones, share information with friends. If you have any questions, they can be set in the comments.

Why do you need navigation?

A few more decades ago, navigation did not use ordinary people, but in America the developers came up with how to use it in ordinary life. Now ordinary people can solve different household tasks using GPS:

find the road to the forest;
navigate in any city of the world;
find the right addresses and objects near himself;
avoid congestion on the roads;
fix your own physical activity and speed of movement.

At the same time, the use of navigation in applications has the opposite side - the phone battery is faster discharged. This is especially noticeable in the devices using a standard module. In modern smartphones, install a -gps add-in, reduction of resources on the satellite search. The battery discharges slower, and after the start, the system quickly determines the location of the device. Use to obtain satellite and mobile network information allows you to determine the coordinates more accurately.

Today, almost every device is able to replace the navigator. It is not about expensive models where many different functions are present. Even in the most budget smartphone install GPS. Enable this feature is quite simple, probably even a beginner user will cope with it. But, as practice shows, even with such a seemingly elementary effects may arise. Let's look at how to include GPS on Android?

GPS switching on

To go to switch on the navigation, you need to go to the menu and open settings. In a new window, you need to find the section "Location" and open it. How to enable GPS on "android"? To do this, click on the switch. Of course, in different versions it will be different, but you will need to choose a mode of operation. What are they?

How to enable GPS on "Android 5.1"? In the new version, you can find the navigation button in the "curtain". To go to the GPS settings, you must click on this button and hold a bit. How to enable GPS on "Android 4.4" and earlier versions? To do this, you need to be guided by the foregoing instructions.

Additional components

So, we looked at how to include GPS on Android. This is not the only problem that is found in many users. Another story is setting up navigation. Of course, it is a bit more difficult here, but if you follow the proposed recommendations, you can configure GPS in minutes.

Before setting, you must install various applications on your device. This does not mean that you need to install a bunch of different navigators, and one, but good. You can install a compass for better navigation. Remember that only those suitable for your version of Android are needed to download applications. Only Google Maps application will be present on the new device, but unfortunately to use it, you will need an Internet connection. Because of this many users it does not suit, they are looking for an alternative. The most popular is "Naviter" (unfortunately, it is paid, but a fairly convenient and high-quality application) and Yandex Maps (free utility).

GPS setup

If you switched to the GPS setting, then you noticed problems. Although, perhaps you have not done this yet. To check the navigation on your device, it must be launched, how to enable GPS on Android, we have considered. Run the navigator and make up the route. If this fails to do or the program incorrectly showed your location, then go to the settings.

Output

That's all. Now you know how to enable GPS on Android and customize it. There is nothing complicated in this, the main thing is to be guided by the rules.

Modern Android--Martphone may well replace full GPS navigatorHowever, "out of the box" Mobile A-GPS / GPS receiver most often works incorrectly. In this article we will tell you how to configure GPS.on loved Android- Martfon.

First of all, you will need to install good navigation utilities on your device. By the way, it can be not only navigators, but also various compasses using a built-in receiver. GPS.. They must be compatible with your version Android OS.. By default, you can use the full-time application. Google Maps.. If it does not suit you due to certain reasons, it is better to still install another program. For example, (paid) or Yandex Maps (free).

Run any program to navigate and make sure it works correctly: Determines your location, it is optimal about the route. If it is not, take advantage of the following tips:

Enter manually setting up a virtual COM port. By the way, it plays a peculiar role of a bridge connecting the built-in GPS receiver and an android device.
Clean, and then update your own GPS.receiver. It is possible to do this through any program - for example, GPS CATATU. Please note that such utilities use the Internet connection to clean.
If A-GPS works incorrectly in a closed room, do not worry. Even if you come to the window or find yourself in a room with a small amount of electrical appliances, A-GPS can show an incorrect location. The advice is here only one: go out and try to understand the program there.
The next way is often helped in the open area. Take a smartphone in your hands and twist it in your hands in different directions, making a few turns of 360 degrees. Must work!
To search for satellites pass faster, check the "Wireless Network" checkbox in the settings Android(GPS satellites function).
You can also try to change the NTP server using the GPS AIDS program. Oddly enough, but it does not require root rights and can be launched absolutely on any machine Android platforms.
To calibrate the compass and accelerometer, as well as updates to A-GPS data, we advise you to use the utility.
And yes, do not forget to make sure that you activated the GPS satellites feature in the "Location and Protection of Mobile Devices".
