It does not work with GPS after updating Android firmware. Why GPS does not work on an Android device: reasons and solutions. The navigator does not work: more reasons

Today's gadgets are already installed so that you can find your place in the world without having to rely on GPS navigators. Sometimes this is necessary for the correct operation of the add-ons, sometimes to create the correct route. If GPS doesn't work on Android, it becomes awkward. What can be done and what can be done to solve this problem?

Either way, it’s bad to catch or not catch the satellite signal because it’s in a closed area. If you want to take care of your business, it will be better to grow on the street. Ideally, the space should be free to direct from tall trees and trees, so that the sky is completely open, so that the gadget does not interfere with the signal and connect to the required satellites.

Incorrect GPS settings

All devices are equipped with GPS modules. One is a standard trick, which can be turned on in the settings (Zagalni - Miscellaneous - Mode). When choosing mobile networks or Wi-Fi devices, you will be able to move around the towers without connecting to GPS satellites. This method is the most advanced, but it never fails to give an accurate result.

When you select the “GPS Only” mode, your phone or tablet will connect to satellites, but for which the device will need any time. In this case, you should be on the street in the open air, or you would like to put the gadget on the windowsill. The operation of another module itself requires correct settings. How to check whether or not to catch the device signal? Why should you download and install GPS Test - an add-on for diagnostics.

After launching the program, in the AGPS settings, select Update only, and in Settings - Keep Screen On. Now you need to go to the main program window to start the GPS test on your tablet or phone. However, it is important that Wi-Fi and mobile data are not included in the local settings and are not being used at the moment.

If the diagnostics showed that the devices are not recognized by the satellites, then you should check that the GPS setting on Android was carried out correctly. How to set up GPS? To do this, you first need to acquire some kind of accessory that can block the GPS signal. If this does not help, you need to check the settings of the COM port of the communicator.

flashing was not far away

After further attempts to flash the gadget or specifically the GPS module, not only the system, but simply other parts of it, for example, geolocation, may stop functioning. There is also often concern about using GPS robots on a Chinese device.

To correct this situation, you need to enable AGPS in location and GPS settings. After this, you need to go to the engineering menu through the dialing button (for all phones there is a combination of prices). If you get nowhere, you will have to quickly use a special program, even with root rights. The order of actions in the Android engineering menu:

• On the Satellites tab of the YGPS tab, check the signal so that your phone or tablet can find satellites;
• go to the Information tab and press the buttons full, warm, hot, cold in order (this is necessary to reset the previous settings);
• on the NMEA Log tab click start;
• turn to the Satellites tab and scroll through 5 to 15 rows until the device reaches the maximum number of satellites and the GPS signal scale turns green;
• Go to the NMEA Log tab and click stop.

This method of readings is shown in more detail in the video.

Primary binding and calibration

It happens that the devices are located in some remote locality. In this case, it is necessary to place it on the open space for a difficult hour and tickle it until the search and connection pass.
Sometimes navigation may stop working if the compass calibration is incorrect. Such a phone or tablet will be oriented incorrectly, resulting in a problem with the GPS on the device. For calibration it is necessary to purchase a special add-on, GPS Essentials. After installation and startup you need to:

1. Click on the compass icon.
2. Select a smooth, level surface, place your communicator on it and remove all electrical accessories.
3. Smoothly rotate the device along the skin axis 3 times.

After this, you need to try connecting again and, if necessary, repeat calibration.

Problems with the device itself

If the gadget has been checked and adjusted according to all the rules, it still does not catch satellites, check the GPS settings and find out the reason, only the service center will help you. It may be that the problem is in the device itself.

All modern smartphones and most tablets are equipped with a GPS module. GPS “lays out” routes across unknown locations, identifying your location to the precision of several tens of meters, and also automatically launches certain programs or turns on guesswork in specific locations. Perhaps the only downside of GPS is that it drains the battery of your smartphone (tablet). First, let’s start the GPS and figure out how to properly set up the robot mode. We will look in detail at how it can be done, and also explain how to adjust the GPS using the additional engineering menu in case of incorrect operation.

Modern devices combine the functions of several devices

Setting up the GPS robot mode

GPS is turned on in the notification panel. In the meaning of the icon, it guesses the little needles. You can change the robot mode by going to “Adjustment - Special data - Miscellaneous - Mode”. The system gives you three options: “High accuracy”, “Saving battery power”, “Behind the device sensors”. In more new versions of Android, stinks may be called: “For all the devices”, “For Merezheve”, “For GPS satellites”. Let's figure out what's behind them.

1. "High accuracy"("Behind all the jerels"). The most accurate, and at the same time the most “unpretentious” mode. Indicates the coordinates of your location using available methods: GPS, Wi-Fi and assistance. The space is constantly monitored for the presence of a signal, indicating the location both in the open area and in the surrounding area. The mode is also called A-GPS. Since primary navigators can catch signals including those from satellites, it is not possible for a smartphone or tablet to do so. Additional service information downloaded from the World Wide Web will help speed up searches and connections with companions.
2. "Saving battery power"("For Merezheve"). Vikorist has no drone-free measurements - the GPS module is not affected. In this case, the accuracy of the coordinates decreases significantly. In the case of a mobile operator, the current level is precisely indicated by the Wi-Fi signal, and in the case of a mobile operator - by the radio signal.
3. "Behind the sensors of the device"(“For GPS satellites”). The assignment mode can only be used in open locality - the location of the expansion is determined by the satellite signal. In the case of the applied ones, the signal is wasted, and the place of expansion, obviously, will not be detected.

To optimally drain the battery charge, select the “Behind device sensors” mode and turn on the designated location in the notification panel. If you need to plot a route, then you will need to turn on the designated location and directly enter the navigation fields. If you want to have a battery, and not be bent on the amount of battery drain, then select the “Battery Saver” mode. If the power consumption of the battery does not turbocharge you, and you like, if the system calculates your locality with an accuracy of up to a meter, then your mode is “High accuracy”.

GPS adjustment via the engineering menu

Unconsciously using the GPS module (searching for satellites, ensuring connections to them, stable connections with them) will significantly simplify life, especially at those moments when you are moving around due to unknown locality.

However, in Chinese models that run on the MTK processor, with a trivial GPS connection, the connections may appear unstable, and in extreme cases, the restoration may not appear immediately. Everything is due to the fact that the adjustment module is not entirely correct for work in our latitudes.

In order to adjust the GPS robot, you will have to carry out a series of difficult adjustments. I would like to tell you that you will end everything at your own peril.

Well, the device is responsible for denying the right of the superkoristuvach (also called Root).

1. Turn off GPS and Wi-Fi and go out onto the balcony, or rather into any open space.
2. Go to the engineering menu. To do this, enter the combination * # * # 3646633 * # * #, or * # 15963 # *, or * # * # 4636 # * # * on the keyboard. These may vary as a combination for your smartphone (tablet). In the event that the overinsurance combination did not work out for you, download the Mobileuncle ToolHero program and select the appropriate menu item from it. The program itself is Russified, but the engineering menu axis is not English.
3. You will have a number of bookmarks in the program menu. Swipe to the left, select the Location tab, and then go to the Location Based Service item.

1. In the EPO tab, select Enable EPO and Auto Download. EPO is a system file that contains information about the coordinates of satellites and their flight paths. This active item is not available on all devices. How to use EPO can be found on specialized Internet forums, for example,

Many phones running the Android operating system encounter a problem when they use the GPS module to find GPS satellites or find them, but cannot connect. The reasons for this behavior of the module may be different, let’s look at the main ones:

The settings for connecting to satellites in the setup file are incorrectly specified;

An A-GPS module is installed, which satellites on the phone often do not know on their own;

The module is not working.

I would like to address the problem with the A-GPS (Assisted GPS) module, since Chinese phones, which account for 98% of the drops, are becoming increasingly popular and are driving light brands out of the market.

How does A-GPS work?

The main advantage of a standard GPS module is that it connects not only with satellites, but also with mobile operator towers, which significantly improves the capacity of the location. When this function is turned on, the phone often cannot connect to GPS satellites and requires a “Final restart”, as it will only be turned on. This is not a problem with the Chinese phones themselves, but with the A-GPS module itself, which costs copies in the same way as GPS, and so it does the same. Let's figure out how to set up GPS on Android.

How do you mean whether A-GPS or a GPS module is included on the phone?

If you have a dual-SIM phone and a Chinese manufacturer, you have 99.9% coverage with A-GPS. If you want to go to this, you can go to the engineer menu. This will mean correcting the nutrition of non-practicing contacts with companions.

To enter the engineering menu, you need to dial the current number on your phone: * # * # 3646633 # * # *. If the combination is not specified, you can try entering * # 15963 # * or * # * # 4636 # * # *, but in this section of the menu you may have problems.

After entering the phrase, you will automatically find it in the engineer menu and display the next option:

You need to move to the left and navigate to the “Location” tab.

Now select the first item “Location Based Servise”. If you have the A-GPS tab, then continue with further adjustments. Otherwise, this article will be of little help to you.

Setting up GPS on Android

If you have the A-GPS tab, go to it immediately. You are to blame for the future, I think:

Adjust the settings with yours, adjust if necessary, use the screenshot:

Since everything is clearly written, you can go back one level to selecting the “Location” items and go to “YGPS”.

Here you see that your GPS module does not know satellites, or rather, it does not connect through incorrect inclusion:

You need the “Information” tab. She will carry out basic manipulations.

As you can see, the warto status is “UNANVAILABLE”, and TTFF is hanging on forever. No matter how much you check, nothing will change.

The essence of correcting the search is to click “Full”, and then, after 2-3 seconds, click on “A-GPS Restart”. Then you reset the dependent search process to zero, thereby erasing all previously installed settings, and immediately re-install the module. Without being able to follow the standard configuration (incorrectly), all satellites know the module from a pure arch.

After 10-20 seconds, on the “Satellites” tab you will get your desired satellite, and even through the soft module you will be able to reach them.

I searched from the first side of the booth, on the balcony, apparently, on the other side nothing was found. On the road, you will know all your companions.

Current mobile devices have GPS and GLONASS sensors installed. On devices with the Android operating system, zocrema allows you to immediately determine your location and create routes using maps in your phone, without having to resort to paper analogues. This is especially true for navigators installed in cars. What should you do if GPS doesn’t work on Android? We first find out the reasons, and then we try to correct the situation.

Reasons why GPS does not work on Android devices

The simplest and easiest reason for GPS not working is an inactive navigation module. If your smartphone does not have a navigation module installed, you will need to do it manually. Beginners may not figure out the reason until they open the settings. You need to swipe down in the menu, set the date and labels to notify, and switch “geolocation” to active mode.

After activation, the navigators in the add-ons will begin to function as standard. For many add-ons with a navigator, customer notifications are turned on if the module is not active. Add-ons for adding routes on phone maps are automatically transferred by the user to the menu upon activation of the module before the start of the robot.

If you have activated the module and turned everything on, but the GPS does not respond to your actions, you just need to check up to 15 numbers until the data is entered, they do not work in the blink mode. Visibility from satellites and speed depend on a variety of factors, including the weather and the stability of the mobile signal from the tower. After the first installation, the data will be installed and will open quickly.

An hour is required to get to know a new place even if you are arriving from a new location in another region or country. The smartphone initially identifies its place of origin, and then goes where it belongs.

Here are the reasons why GPS may not work the first time you start it:

• You want to start the navigator in the middle of a crash - park the car and let the device settle in a calm and stable position;
• If you are in a place where you can’t get any contacts, the GPS will not turn on, but you will be connected to the Internet;
• You launch the navigator on the territory with natural translations for the satellite - mountains, growth, future.

After you have identified one of the reasons for overinsurance and fixed the problem, the navigator on Android will ask. If something went wrong - you have problems with the device - go to the service center for software improvements.

If your GPS was working and then stopped, you should be aware of internal damage to the device. Before sending it to the service center, try to use it yourself, and yourself - reset it to the factory level, you may have tweaked the settings and removed the device from the panel.

Using the additional Chartcross ltd program, you can run a GPS Test to check the satellite coverage area in your area. If the module operates properly on the device and does not have a transcode for the signal, you will see on the add-on screen a map of the sky above you with dots that indicate the location of the nearest satellites.

How to set up GPS on Android

There is no need for special adjustments, everything works automatically. If you want to adjust this, you can change the way the signal is detected:

• The signal will be highly accurate if it covers all receiving points - the GPS module on the phone, Wi-Fi Internet and satellite;
• Energy saving - this mode when using telephone networks and Wi-Fi Internet;
• Only GPS - work with satellites.

You need to go to settings in the “Geodata” section and check the required item. The navigator will run additional special programs.Є add-ons for a smartphone, for example, Maps.me. Its functionality also includes handy cards that you can use offline, and a free online one.

Using GPS is one of the standard functions of modern smartphones; all mobile devices can use various navigation programs on the Google Maps platform and retrieve the exact coordinates, for example, of a place locating, localizing any other object on the map, planning transfer routes, etc. .d.

However, various Android devices are equipped with different types of GPS sensors, which differ in their technical parameters.

Apparently, at the core of the work of such sensors there is also a GPS signal that can protect the skin of the smartphone model.

In addition, the strength of the GPS signal is also seriously affected by other important officials by changing the system settings of the device so that the security software is checked, the strength of the connection and the firmware version of the device.

From this article we have collected several recommendations, How to move the GPS position in Android smartphones and tablets . Otje

To start with, you need to make sure that your Android device has the GPS function activated. For this we go to “ fine-tuning"To the device (with a rotating axis such as Lenovo P770), the section is opened" my place is growing"(Location Access) and there we enable (check the boxes) options" Access to information about my locality"(Access to my location) and" By GPS satellites"(GPS Satellites).

GPS calibration
Often, the reason for the decrease in GPS signal strength can be a poorly calibrated compass in the smartphone, as a result of which the device incorrectly calculates the coordinates, constantly showing incorrect data. You can set up a compass in the Android OS using additional special utilities, such as those in Merezha Bezlich. GPS Essentials, For example. After installing this add-on, you just need to launch it and press the button Calibrate. Next, the program independently optimizes the GPS settings of your smartphone.

If, after calibration is complete, the GPS unit becomes unsatisfactory, then you can use the additional diagnostic function to try to determine the cause of the malfunction and error, whether it is related to deficiencies in the installed software, Or the problem lies in the hardware base. GPS Essentials launches an additional test, the results of which show a list of possible reasons for poor GPS performance, and in the process it is also determined, including the number of satellites from which the smartphone receives a clear signal.

If you have not been able to move the GPS position (or understand the reason for the unclear operation) using the GPS Essentials utility (and this may not be the case), then as a last resort you can reset the GPS module of your Android smartphone. The problem is that sometimes the device “gets stuck” on satellites that are within its range, and stops receiving signals from available satellites. After restarting the GPS module, all settings are reset and the settings are updated. On our Lenovo P770, the GPS module was re-engaged with additional utilities GPS Status & Toolbox, Yaku was also downloaded from Google Play.

After installing and launching the program, you must go to the A-GPS manager menu ( Manager A-GPS State) And just press the button Reset Data. The program will remove all necessary adjustments to the GPS module and update the factory settings. This optimization method can be used for preventive purposes, if the GPS location in the smartphone becomes unstable again.

flashing the device
Another radical way to improve the GPS capacity of an Android smartphone or tablet is to flash the firmware to the device. However, only cashiers can get through it effectively. Lack of knowledge, however, may not only not correct the situation with GPS, but, most likely, cause the device to go wrong. Prote, with a competent approach, flashing allows you to remove shortcomings in the GPS work and significantly improve the accuracy and brightness of the GPS signal, as well as speed up the search for satellites. Of course, don’t forget about backing up your data.
