GPS on the phone does not find satellites. GPS does not work on iPhone, how to fix it


GPS does not work on Android, what should I do?. Navigation systems on mobile devices(smartphones and tablets) in Lately have become necessary not only for motorists, but also for pedestrians, thanks to their good ability to build walking routes. But quite a lot of users have to deal with something that does not work or works poorly GPS system on Android. This may result in problems different types, depending on what exactly caused the breakdown.

Definition

What is GPS? This is a navigation system - strictly speaking, GPS / GLONASS is a navigation module that allows you to use many applications that use navigation. This Yandex. Cards, Google. Cards, displaying the weather in your city, determining your actual location and configuring the device taking this factor into account (weather, time zone, etc.).

Routes are most often set using this system. They can be by car, on foot or by bicycle. In fact, when working properly, such a module helps to find any object marked on the maps.

Problems

But in some cases, certain problems may be detected in the operation of such a module. Their nature is different, but they equally interfere with working with the system:

  • Complete inability to determine locations;
  • Inaccurate location determination;
  • Slow data update or complete absence updates (for example, you move in space or turn around, but the pointer on the map does not change its position for a long time).

Most problems can disappear on their own when you restart or when you move to another area of ​​the map. But if this does not happen, then you need to know what caused them and how to eliminate them.

Possible reasons

There can be many reasons for this type of problem. But all of them can be divided into two large groups - hardware problems and software problems. We speak about hardware problems when the defect is present in the physical navigation module itself, and about software problems when something is incorrectly configured in software smartphone or tablet.

Important! Problems software type They are quite easy to set up and fix yourself. When we're talking about about hardware failures, it is better to entrust the matter to a service center, since for a non-specialist the repair process can be quite complicated. And there is a risk of making the situation worse.

Rice. 3 Geolocation problems

Hardware

One of the most common problems occurs during the first launch of the module, that is, when you first launch an application that uses GPS on a new smartphone. Within 15-20 minutes, geolocation may not work, nothing will happen, the location will not be determined. When you first start it normal condition, but this should not happen again in the future.

A similar situation may arise if you have traveled a significant distance, for example, moved to another country or region, with the navigation module turned off. In this case, when he first starts in a new place, he will also need time to “think.”

The problem may also occur when starting on high speed, for example, while driving a car - in this case, the module will “slow down” for the first time after switching on.

Keep in mind that GPS does not work in buildings - indoor navigation will not be carried out. Your approximate location in the building is determined using the zone layout wireless internet and towers mobile operators, but not GLONASS.

Software

The GLONAS module can be disabled through the phone settings; often on new models it is not enabled by default. Therefore, many beginners who are not accustomed to using Android do not turn it on before starting to use navigation applications. By the way, most popular and modern applications This type notifies the user that he needs to enable navigation.

Inaccurate location determination may be due to the characteristics of the zone. The system does not work equally well in all areas due to the nature of satellite operation. There are “blind” zones that the navigator misses or does not detect accurately. It is impossible to fight this.

Rice. 5 Stable geolocation

Elimination

Troubleshooting is usually quite simple. But if after taking all the above measures the problem has not been resolved, it is possible that the problem is a faulty module and it requires replacement at a service center.

Hardware

There are no ways to “cure” the program freezing after the first launch of the navigation module. The user just needs to wait about 15-20 minutes after the first launch of the application - during this time, the electronic components of the navigation device will adjust to the current operating conditions and the location will be determined.

That is why it is recommended to run this module for configuration immediately after purchasing a phone, so as not to wait in a situation where you need it urgently.

Rice. 6 Location problems

Software

Turning on navigation on your smartphone is quite simple. Most often, the application itself “asks” whether to enable navigation when it is disabled. Then you need to click on “ YES" or " OK" in the pop-up window, and the application itself will enable geolocation. If such a notification does not appear, enable it manually, following the algorithm:

1. On the unlocked screen, on the desktop, pull out the menu by sliding it from the top of the screen down;

Good question. Today, many owners of Android smartphones are interested in this question. Once upon a time, when I bought my first Android device, I also encountered the same problem. I am a driver and the first thing I wanted from a smart device was, of course, navigation. I bought a phone, turned it on and immediately started looking for satellites. And what do you think? I waited for about thirty minutes and still nothing. I already had the idea that the phone was defective, without a GPS module. In fact, everything is simple, I poked around a little in the settings and this is what I found:

  • the first thing you need to do is go into the settings of your smartphone and find the “my location” item there;
  • then activate the GPS module and click “by GPS satellites" You don’t have to check the boxes next to “access to my geodata” and “by network coordinates”;

  • as soon as you have entered the settings of your GPS, you need to check the box next to “GPS EPO assistance data”, then click on the “EPO parameters” item;

  • Now check the box next to “autoload”. If you have access to the Internet, you can immediately download data on the position of the satellites.

That's all, now that the satellite location data has been downloaded, your smartphone will find them almost immediately.

What is EPO?

EPO (Extended Prediction Orbit) translated into Russian means a system for predicting the position of satellite orbits. EPO is the property of MediaTek one of the server's innovations in offline mode based A-GPS technology. The system provides a satellite orbital position forecast for up to 30 days, which can significantly improve the user's experience during the first determination of the location of GPS satellites.

The settings that I told you about apply only to devices running MTK processors from MediaTek.

I hope the article was useful to you and you were able to set up your smartphone.

Some users are faced with the problem of GPS not working. What to do in such a situation?

If GPS does not work on Android, then the reason may be hidden in the navigation module. This problem is most often encountered by beginners who do not yet fully understand how the phone works. To solve the problem:

  • Activate navigation by sliding the top curtain, where all the necessary icons are hidden
  • Activate the “Geodata” item
  • Now turn on any navigation program and start using it

By the way, some applications notify users that the reception of geodata has been disabled. For example, Navitel. They display a special alert and even immediately go to the navigation activation menu. Once everything is done, you can start planning the route.

After turning on geolocation and settings, there is no result? The problem here is most likely your impatience. If this is your first time running GPS module, then wait about 15 minutes. During this time, the electronics processed information from the satellites. All other launches will be carried out much faster.

You should do the same if your navigator was working in another area and you brought it turned off. The device needs time to determine its position.

Reasons why GPS does not work on Android

  • If you are trying to determine your location on the go then worth a stop And stand a little to the navigator could tune in. For some devices The chips are slightly slow, so they take some time to set up
  • You entered a building, but GPS will not work through thick walls.
  • You have entered the zone adversely affecting signal reception - many trees, rocks or high-rise buildings. In this case, you just need to go out into the open area
  • If the option is not activated, then you have a direct route to a specialist, since if problems arise with GPS, namely, if it previously worked well and suddenly stopped, then this indicates internal failures
  • If you don’t want to contact a service center, then first do a factory reset, perhaps this will solve the problem

To check the signal reception level, use GPS Test. If the geolocation option is activated, and the chip itself is working, and you are outdoors, then the map will show you the points where the satellites are located.

Video: Setting up and testing GPS on an Android smartphone

Availability GPS navigator and in Android smartphones or tablets will surprise no one. A GPS navigator on mobile platforms also has an advantage - it can work without connecting to a satellite, but only by working with mobile towers, but in in this case You can only get location coordinates. To globally determine your location, you 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 service center.

  • 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 GPS settings, the module still showed 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. On to the pros this method can be attributed fast speed work, and the downside is that it is not an accurate indication of the location. More slow way- This satellite GPS navigation.

This technology makes it possible to recognize satellite position, using the network and at the same time receiving data much faster.

  • Android GPS can work without a mobile connection.

From various managers mobile networks you can hear that GPS does not work on Android if it is not in the zone 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

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 it is necessary permanent connection to the network.

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

Few people know this rule. But those who have worked with portable GPS are familiar with 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 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.

Many Android smartphone users often complain about problems with GPS. Some claim that it can take forever for a smartphone to determine their location, while others may claim that GPS doesn't work at all.

Most often, similar problems are encountered by users who have flashed their smartphone or who have brand new Chinese gadgets. However, some people note that they also have problems with GPS on new gadgets from trusted companies.

In today's article, we will look at the reasons why GPS on a smartphone may start to work poorly or stop functioning completely, and we will also look at several solutions for these problems.

Ok, let's talk about the reasons why the navigator and GPS may not work well on Android. There are several reasons for this:

  • deactivated GPS module;
  • disgusting custom firmware for a smartphone;
  • damaged GPS module;
  • inappropriate GPS Almanac;

GPS stopped working on Android? Try the tips below!

Solutions for problems with GPS on Android

Activating the GPS module

So let's start from the very beginning simple solution, which you’ve probably already reached yourself. Before using the navigator on your smartphone, do not forget to activate the GPS module. When starting some navigators, this module can be activated automatically, however, in some cases the user needs to do this independently. Make sure that the GPS module is activated and try using navigation again.

Firmware change

However, what if this module seems to be functioning, but geolocation still does not work? If you recently reflashed your smartphone, then the reason may lie in the firmware. Read reviews from other users about this firmware version and see if they have similar problems. Install some proven Android firmware on your smartphone, where GPS works normally.

Re-recording of the Almanac

But what to do if the GPS module works and you haven’t reflashed your device? As we mentioned in the reasons, owners of Chinese smartphones often complain about poorly working GPS. For example, you can find many users on the Internet Meizu smartphones With similar problem. Let's assume that you have approximately the same device.

The cause of problems with GPS is Chinese smartphones concludes that they often contain an irrelevant Almanac for our hemisphere. An almanac is a type of data transmitted by a GPS satellite that contains the orbital parameters of all other satellites. To fix the GPS problem in this case, you will need to rewrite the Almanac. This can be done by following these steps:

  • activate in your settings smartphone A-GPS, and then GPS;
  • then log in engineering menu Android by entering the code *#*#4636#*#* into the dialing menu;

    The note: if specified secret code does not work, then you will need to find out the code for your smartphone on the Internet. Owners of smartphones with processor MTK In general, you will need to use the MobileuncleTools utility.

  • as soon as you open the engineering menu, go to the tab called “YGPS”;
  • now take a look at "Satellites" and check if signs of a signal appear;

    The note: if they appear, then the theory with the wrong Almanac has been confirmed and you can continue to follow the steps below.

  • go to the “Information” tab and press the following row of buttons one by one: full→warm→hot→cold;
  • next you need to click on the “Start” button in the “NMEA Log” tab;

    The note: it is precisely this action that will ensure the recording of a new Almanac corresponding to your region.

  • now go back to the “Satellites” tab and wait until as many satellites as possible are detected and the signal scales turn green;
  • as soon as all satellites are detected, return to the “NMEA Log” tab and click on the “Stop” button.

The problem with the Almanac should have been resolved. We hope that you understood why navigation did not work on your Android smartphone and you corrected the operation of your GPS module. Well, if you tried to follow all the above recommendations, but the problem with navigation was not resolved, then we advise you to contact your nearest service center, since your GPS module may have failed.
