• GPS does not work. Speed ​​up GPS, GPS reception is bad, problems with GPS? Solution: Speed ​​up GPS on Android

    Modern mobile communication devices have GPS and GLONASS sensors. On devices with the Android operating system, in particular, this makes it possible to always determine your location and create routes using maps in your phone, without using paper counterparts. 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 for the data to load, they do not work in lightning-fast mode. Visibility from satellites and download speed depend on many factors, ranging from weather to the stability of the 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 your phone, Wi-Fi Internet and satellite;
    • Energy saving is a mode when telephone networks and Wi-Fi Internet are used;
    • 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.

    The presence of a GPS navigator in Android smartphones or tablets will not surprise anyone. 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 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 a service center will help here.

    • Incorrect GPS setting. 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 can take 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. To operate correctly, 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 a specialist at a service center.

    Android phones contain a GPS module that allows a large number of applications to determine location and also navigate the area. 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 the location settings of your Android phone, you will see two definition options to choose from. One definition is called a network position. This option calculates coordinates using mobile towers or via Wi-Fi. The advantages of this method include fast operating speed, but the disadvantages are not an accurate indication of the location. A slower method is GPS satellite 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

    • Maps matter when Android GPS works.

    If you open Google Maps without a network connection, your smartphone will display the error “This application requires an active data 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.

    Incorrect operation of the GPS module is a fairly common problem with Android devices. The system can connect to satellites, but navigation will still not work. In some cases, the defect is associated with a breakdown of the gadget’s hardware, but most situations can be resolved using software methods. Below we describe what to do if GPS does not work on Android.

    First, let's determine how the navigator on the phone works. Yandex.Maps or navigation from Google contacts the system satellites and requests data about the user’s current location. Based on the information received, an optimal route is built or public transport is selected. If the GPS module stops functioning, normal navigation operation is impossible, even using A-GPS technology. The main causes of failure are usually software problems, but in some cases the source of the malfunction is the failure of a hardware module.

    Geolocation services do not work on Android if the settings are incorrect. The defect may also be caused by the installation of incompatible firmware or the lack of necessary drivers.

    The navigator from Google or Yandex does not work well even with a weak satellite signal. It is worth remembering that programs do not always display location correctly, and you should not rely on the system when hiking or off-road. To troubleshoot, let’s look at the causes and solutions to popular problems.

    Reasons for no signal

    There are two main groups of faults: hardware and software. The former can be fixed by qualified specialists in service centers, while the latter can be fixed at home.

    • Hardware - a component can fail after a mechanical impact on the device body, for example, a fall or a strong blow. The cause of the breakdown may also be liquid entering the main board, followed by oxidation of the contacts.
    • Software - infection with malicious software, incorrect firmware or update failures - all these malfunctions can damage the location driver.

    The first thing to do if the GPS sensor does not work is to restart your smartphone and scan it with an antivirus. It is possible that the device's RAM is full and there are not enough processor resources to activate communication with satellites.

    Incorrect setting

    Correctly setting the smartphone parameters is the key to the correct operation of the GPS system on Android.

    • If Android does not find the location, go to the device settings, then “General”, and then open “Location and modes”.
    • On the Location tab, specify your preferred location method. If you select Satellites Only, Android will not use A-GPS technology, which collects data from nearby cellular and Wi-Fi networks to improve geolocation accuracy.
    • Try setting the “Mobile networks only” mode and check the functionality of the cards. If navigation turns on, there is a problem with the driver or hardware.
    • When GPS on Android does not turn on (the system does not respond to switching the option), there is probably a problem in the firmware. Perform a full reset or contact a service center.
    • To reset your location settings, click on the “Backup and reset” tab, then tap on “Reset network and navigation settings.” Sign in to your Google account to confirm.

    Important! All saved passwords from Wi-Fi access points, as well as cellular network data will be deleted.

    The described method helps eliminate most problems with the software.

    Incorrect firmware

    The consequences of careless firmware on Android can be quite unpredictable. Installation of third-party OS versions is performed to speed up the operation of the gadget, but as a result, the phone modules stop functioning.

    If you decide to reflash your device, download firmware files only from trusted forums - XDA and w3bsit3-dns.com. Do not try to flash your smartphone with an OS version from another phone, as the drivers necessary for operation may no longer function. If the device has become a brick, perform a full data reset.

    • Press the volume up and lock buttons for 5-7 seconds. When the Android logo appears on the screen of the turned off gadget, release Volume Up.
    • The Recovery menu will load. Select “Wipe Data/Factory Reset”, confirm Hard Reset.
    • To reboot your smartphone, tap “Reboot system now”. Setup will take a few minutes when you turn it on.

    The method is suitable for devices with damaged firmware. The GPS module will restore functionality after switching to the factory version of the OS.

    Module calibration

    In some cases, it is necessary to perform a quick calibration of the device.

    • Open the “Essential setup” application, you can download it for free from the Play Market.
    • Tap the compass icon and place your smartphone on a flat surface.
    • Tap the “Test” button and wait 10 minutes until testing ends. Once completed, try turning on satellite navigation.

    Hardware problems

    Cheap Chinese smartphones are often equipped with low-quality satellite communication modules. The problem can be corrected by replacing the corresponding module at a service center. Malfunctions occur on both Android and iOS phones.

    Conclusion

    If navigation on Android does not work or you cannot connect to satellites in open areas, determine whether the cause of the defect is in the gadget’s parameters or whether the electronic board has failed. Repairs to hardware faults should only be carried out at authorized service centers.

    Based on Android, it does not detect / does not detect the location correctly. Navigation does not work or does not work correctly. What to do and how to fix it?

    Many users encounter a problem when phone or The Android tablet starts acting up. It seems that nothing happened that could cause a malfunction, but it does not work as it should.

    For example, the device has problems with the fact that it has ceased to determine its location either tablet e or The phone's navigation is not working properly. The reason for this may be:

    1st: Software glitch- i.e. the problem is a software glitch

    2nd: Hardware failure- i.e. the problem is in the hardware (i.e., replacement or restoration of spare parts for the gadget is required)

    However, do not rush to get upset - in 90% of cases there are problems operation of location recognition, geolocation, satellite detection, navigation, etc. functions. smartphone a or Android tablet is to blame software glitch which you can easily fix on your own.

    Fixing a software glitch:

    Method 1. Quite simple - go to "settings", find there "backup and reset", in which you choose full reset settings with deletion of all data. Be careful, using this method is often effective, but it entails deleting all photos, contacts, passwords, music, games, videos and, in general, all information stored on your smartphone e or tablet e. Therefore, first save everything you need by connecting the gadget to your computer. If this method does not suit you, or if even after this the problem is not resolved, see Method 2.

    Method 2.

    Based on solving problems with communication and network reception phone number and tablets based on Android by introducing additional software. Utilities that control all processes inside gadgets. Today, there are quite a lot of them, however, the fewer functions an application contains, the more effective it is, as a rule. The best way to monitor system functions, corrects, and correct all possible settings and synchronization errors is a small, easy-to-use, free utility for Android-based devices. You can download the application from Google Play and see its additional options in the description. After installing the application, all that remains is to launch it. Further, in principle, nothing more is required from you. The application will take full control of the device's functions. (By the way, among other things, the gadget will begin to charge 20% faster, and its performance will also increase significantly, which will affect the loading speed and operation of all applications, games, and the system as a whole. On average, after scanning, the system runs at 50% faster.)

    • Also, to achieve maximum data exchange speed over the Internet, it is recommended to install a high-speed browser on your Android device Yandex Browser You can download it from Google Play.

    Method 3.

    Changing the device software, or as it is also called "re firmware". This method, as a rule, requires certain skills and can be solved by contacting the Service Center. To carry out this task yourself, you need to contact the website of the manufacturer of your device, download the utilities necessary for flashing the firmware and the firmware itself, and then reinstall it on your gadget.

    If none of the methods brings results, unfortunately, you will have to contact the Service Center for repairing your tablet a or smartphone a.

    An Android phone or tablet does not detect / does not detect the location correctly. Navigation does not work or does not work correctly. What to do and how to fix it?

    In this post I’ll try to systematize the information I collected on the topic of speeding up GPS on Android. I’ll say right away that most things are relevant if you have root and S-OFF (I immediately installed the custom RcMix 3d Runny firmware on my smartphone). The post does not pretend to cover the issue completely - I am simply sharing my experience.

    Previously, I waited for 20 minutes - the satellites were never caught. Now, as a result of applying the tips described below, the coordinates are determined in 2-3 minutes with a cold start, and approximately 30-40 seconds with a hot start.

    1) Use the time synchronization program ClockSync (needs root, found):


    — before starting Navitel (or another navigator) through the ClockSync program, synchronize the time on the phone;
    — after starting Navitel, synchronize the time on the phone through the ClockSync program.

    2) Edit the file gps.conf(needs root): in parameter NTP_SERVER register yours location.

    For editing it is convenient to use the FasterFix program.
    For example, I had

    NTP_SERVER=north-america.pool.ntp.org

    and for Ukraine it was necessary to register

    NTP_SERVER=ua.pool.ntp.org

    Accordingly, for Russia

    NTP_SERVER=ru.pool.ntp.org

    After which reboot apparatus.

    3) Advanced editing gps.conf (root needed, found).

    In this case, it is convenient to use the FasterGPS program for editing. This program can also do what is described in paragraph 2.
    You need to add the following to the file:

    NTP_SERVER=ua.pool.ntp.org - if you did not do this in step 2, then be sure to do it now (as you understand, this is a setting for Ukraine)

    INTERMEDIATE_POS=0
    ACCURACY_THRES=0
    REPORT_POSITION_USE_SUPL_REFLOC=1
    ENABLE_WIPER=1
    SUPL_HOST=supl.google.com
    SUPL_PORT=7276
    SUPL_NO_SECURE_PORT=7276
    SUPL_SECURE_PORT=7276
    CURRENT_CARRIER=common
    DEFAULT_AGPS_ENABLE=TRUE
    DEFAULT_SSL_ENABLE=FALSE
    DEFAULT_USER_PLANE=TRUE

    After which reboot apparatus.

    Fortunately, you can edit gps.conf manually (for example, through RootExplorer), FasterGPS is just a front-end for editing. But it’s calmer with him, because... You cannot leave spaces at the end of lines or empty lines in gps.conf.

    4) Use a program that helps determine coordinates as quickly as possible. Of the several I tested (GPS Status, GpsFix, GPS Test), GPS Status turned out to be the most effective and functional (root is not needed). Turn on GPS, turn on mobile Internet, launch GPS Status, and there:

    Menu -> Tools -> A-GPS Data -> Load

    Lyrical digression:
    when you watch how GPS status confidently catches satellites one after another
    (engaged/caught: 0/1 .... 1/2 ..... 3/3 etc.),
    waiting time goes by much faster.

    By the way, this program also has a “Radar” function: you can mark the place where you are now and then return to it.



    We also remember simple things:

    • After turning on the GPS, immediately turn on the mobile Internet - this way the smartphone will determine the coordinates much faster, after which the mobile Internet can be turned off.
    • GPS drains the battery, but the always-on screen drains the battery even faster. At the same time, if you lock your phone, GPS is turned off. If you want the GPS to work longer (for example, when walking around an unfamiliar city), reduce the screen brightness to the required minimum.
    • GPS in smartphones is inherently weaker than in GPS navigators
    • GPS does not work indoors - only outdoors
    • In some smartphones, the GPS antenna is located at the bottom of the device. You can try to speed up the search for satellites by turning your smartphone 180 degrees. Or don’t hold it in your hands, but put it, for example, on a bench.
    • If you still need to use GPS indoors, you can go out onto the balcony or go to the window. The same trick works in minibuses - you just need to sit near the window.
    • In cloudy weather the signal is worse. Fishing is also worse among high-rise buildings. Sometimes it is enough to move 100-200m away from 16-story buildings - and the result becomes noticeably better.
    • During a cold start while moving, the signal reception is worse than when standing still. Force yourself to stop and wait until your smartphone catches the satellites (launch GPS Status and admire how cleverly it catches them one after another) - in the end you will spend less time this way than trying to do it on the go.
    • In theory, you need to catch 3 satellites to determine the coordinates, and 4 to determine the coordinates and altitude. In reality, GPS Status determines all parameters when 6-7 satellites are detected. The maximum that could be caught was 9-10.

    PS - I also want to recommend a good review of programs for working with GPS - Workshop: using GPS on Android to the maximum - be sure to check it out, there is a lot of useful stuff there.

    PPS - from what I use from this review myself, I want to recommend the excellent profile manager Llama.

    Strictly speaking, it has nothing to do with GPS:

    What makes Llama special is that it doesn't use GPS to determine coordinates, but rather relies on cell towers. However, it was decided to include it in the review as an alternative to GEO-Tasker.

    The program receives location data using data about operator towers, and depending on this, it can switch profiles. For example, at home - normal during the day, quiet from 23 to 6, when you leave the house - loud, in church - no sound, at work - quiet, etc. By combining zones and events, you can customize absolutely everything for yourself and forget about manually switching profiles.

    Speeding up GPS on Android - 2


    In the first part of the article, I described programs and techniques that speed up GPS on Android devices. An example of an alternative file was also given there gps.conf, speeding up the process of determining coordinates. For comparison, previously, on my HTC Inspire 4G, satellites were caught in a matter of minutes, after using it - 30-60 seconds. Much water has passed under the bridge since then, but I have not stopped searching for an even faster solution. And today I can present to you a new gps.conf file synthesized from several found on the Internet, with which the process of determining coordinates takes 5-10 seconds. Those. by the time the navigation program is launched, the coordinates have already been determined. The file is adapted for Ukraine, but it can be easily remade for other European countries - in the first few lines we change “ua”, for example to “ru” - we get a file for Russia, etc.

    NTP_SERVER=ua.pool.ntp.org NTP_SERVER=0.ua.pool.ntp.org NTP_SERVER=1.ua.pool.ntp.org NTP_SERVER=2.ua.pool.ntp.org NTP_SERVER=3.ua.pool.ntp.org NTP_SERVER=europe.pool. ntp.org NTP_SERVER=0.europe.pool.ntp.org NTP_SERVER=1.europe.pool.ntp.org NTP_SERVER=2.europe.pool.ntp.org NTP_SERVER=3.europe.pool.ntp.org XTRA_SERVER_1=/ data/xtra.bin AGPS=/data/xtra.bin AGPS=http://xtra1.gpsonextra.net/xtra.bin XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin XTRA_SERVER_2=http://xtra2 Q osHorizontalThreshold=1000 QosVerticalThreshold=500 AssistMethodType=1 AgpsUse=1 AgpsMtConf=0 AgpsMtResponseType=1 AgpsServerType=1 AgpsServerIp=3232235555 INTERMEDIATE_POS=1 C2K_HOST=c2k.pde.com C2K_PORT=1234 SUPL_HOST=FQDN SUPL_HOST=lbs.geo.t-mobile.com SUPL_HOST=supl.google.com SU PL_PORT =7276 SUPL_SECURE_PORT=7275 SUPL_NO_SECURE_PORT=3425 SUPL_TLS_HOST=FQDN SUPL_TLS_CERT=/etc/SuplRootCert ACCURACY_THRES=5000 CURRENT_CARRIER=common
