• How to set up GPS on Android. Reasons why GPS does not work on Android. Brief instructions on how to enable location services

    Don't you like that the GPS on your Android takes too long to "search for and acquire satellites"? The location accuracy is worse than 10 meters? Did you think that “this is how GPS actually works”? Nothing of the kind. Your GPS can provide an accuracy of +-5 meters, or even more accurately. And I will tell you how to achieve this. And no more “patches” or third-party and “gemorrhagic” in the use of “GPS utilities that speed up the search for satellites and increase accuracy.” Everything you need is in your device. The manufacturer simply enters “medium-light” “calibrations” there - naturally, he won’t calibrate each phone individually. And where is the manufacturer? In China, but you need to calibrate where you actually use it. The instructions below were collected by me from different sources in parts and checked, except for the part “ensuring maximum accuracy,” which I will check later and make an addition, but even without it, time “ Cold start" GPS, after rebooting the phone, it was possible to bring it to less than 20 seconds, instead of 1-2 minutes before calibration. At the same time, the first satellites are captured in less than 3-4 seconds, and " GPS capture" (localization by satellites, when " stops blinking " GPS search"and the body switches to working on satellites) - less than 10 seconds (sometimes up to 40 seconds, but less often - depending on the accuracy of your smart watch and the visibility of satellites).
    To decide which one you prefer, you can read impressions of both methods here: http://vyacheslav.blogspot.com/2013/07/android-gps.html. I personally recommend the “native GPS calibration method” (described below) - it gives the same results, and in my opinion is much preferable and easier to use.
    It should be noted that with the help of the program described here: http://vyacheslav.blogspot.com/2013/07/android-gps-6.html, the activation speed from the “cold” state is still a little faster. but more hegemonic, and because of its “deep penetration into the system GPS Android", it can "throw down" the calibrations of its "native system", which are discussed below. Plus, everything that needs to be done with its help, before each turn on, the GPS makes the startup using it really slower than in the option outlined in this note.


    Added 08/30/2013. Before starting calibration, look at this note and follow the procedures described in it: http://vyacheslav.blogspot.com/2013/08/gps-android-jb-411-cink-king-gps.html. This is especially true if you have serious problems with GPS, such as “it holds the satellites very poorly” and the “lock” “falls” at the slightest weakening of the signal, plus after that, the GPS will “hold” more satellites at the same time, which will improve both stability and accuracy . Without these procedures, I could not “bring the GPS back to normal” under JB 4.1.1 Cink King. Then perform calibration according to the method. outlined below in this note.

    *italic font The points necessary to achieve generally theoretically possible accuracy are highlighted. Italics may be omitted, this will slightly reduce the accuracy (actually 2 times), and will not affect the “cold start” speed.
    **Before the procedure, find out the code for the engineering menu of your device - you will need it.

    1. GPS accuracy, and especially the speed of “capture after a cold start,” greatly depend on the accuracy of the time setting on your device. Usually, in the “Date and Time” settings, “synchronize time over the network” is set. I had it too. But as it turned out, the device uses to set the time cellular signal operator, which in some cases can give time setting accuracy worse than + - several minutes, and in my case (Kyiv, Life operator) gave a difference from real time of as much as 3 seconds. In general, feces, and not “exact time signals”. There is also the option to “determine the time using GPS,” but if you don’t live in a village, then this will eat up a lot of battery, and will be of little use - neither in an apartment, nor on the subway, nor in a minibus, nor in the office... Well, you get the idea.
      Therefore, let us first take care of setting the most accurate possible time. For this I set free program ClockSync, from here: https://play.google.com/store/apps/details?id=ru.org.amip.ClockSync&hl=ru, you can also get it from here: http://4pda.ru/forum/index. php?showtopic=171610 . You can also use the technique that I described here: http://vyacheslav.blogspot.com/2013/07/android-gps_12.html - it does not require installation additional programs, but requires manual editing several system configuration files.
      Next, we decide on the reference exact time server that we will use. It is important that it be as close to you as possible and that the ping time to it be minimal. To begin with, the addresses of the “pools” - for Ukraine this is ua.pool.ntp.org, for Russia ru.pool.ntp.org. If you are in another country, look here: http://www.pool.ntp.org/ru/.
      Now we launch the terminal, and in it the command “ping ua.pool.ntp.org”, and look at the response time. We do this 10 times - each time it will contact a random “pool” server, and usually a different one. Even for Ukraine, the “response” time for different servers ranges from 5 to 60ms (on land), let alone Russia with its size. Accordingly, we write down the IP address of the server whose response time is minimal. We will use it.
      Let's launch installed program ClockSync, Menu > settings. The first item is "NTP server". Enter the selected IP address there. Next, check the box " automatic synchronization", then select "Interval". The smaller the interval, the more often the synchronization will take place, and this is "a little traffic and a lot of battery", on the other hand, in 3 hours my device “goes away” by as much as 160-180 milliseconds... I settled on 3 hours for now. Next, you don’t have to check the “exact interval” checkbox - it will save the battery a little, I personally checked it. "High precision mode" - check it, especially since synchronization will sometimes go through cellular transmission data at a very unstable speed (you don’t have to set it - the accuracy will drop, but the battery consumption during synchronization will significantly decrease). We also set “define time zone”,
      Exit the settings menu, click “menu”, and select “synchronize” - how much your device is “past time” can be seen on the screen. Yes, in the settings menu after a day you can see how fast/late your device’s clock is per day (my Fly IQ 450 is 9.21 seconds per day).
      PS automatic time synchronization is only possible on a “rooted” device. If you are not rooted, there is in the program " manual mode", but the accuracy will not be the same.
      Note - added later. There is also a second way to accurately synchronize time, without installing an additional program, I described it here: http://vyacheslav.blogspot.com/2013/07/android-gps_12.html. After comparing the results, I chose this method, but it requires some editing of the configuration files.
      It is also advisable, if you have a rooted device, to edit the /system/etc/gps.conf file. Namely, in the first line, after “NTP_SERVER=", replace the “default” one indicated there with a more suitable one for your country - for example, for Ukraine at ua.pool.ntp.org, or even with a previously defined IP address, but this will less universal and sometimes fraught with failures if a specific server does not work, so ua.pool.ntp.org is more universal, but the IP address in this field can further speed up the initial cold start. Editing can be done using "Root Explorer".
      Over time we figured it out. Next.
    2. Let's go to the phone settings. Location. We mark the items: “By network coordinates”, “GPS satellites”, “Auxiliary data”, “AGPS”, the rest is “to taste”. Now go to the "EPO Settings" item. Turn off "EPO" during calibration. Everything is here.
    3. Launching Google Earth , In the settings, we switch it to show coordinates in the format of degrees and fractions. We are looking for a place nearby where we will carry out calibration. It should be a fairly open place, such as a square. We select the point where we will stand during calibration (select signs to stand exactly at it later), point the cursor at it, and write down the shown coordinates to the last digit. The preparation is over - let's go "to the field" :) with the phone.
    4. If you used p3- we stand EXACTLY at the point we previously selected. Let's launch " root explorer", go to the /data/misc folder, delete the mtkgps.dat file. Load the latest AGPS data - for example, through the GPS Status program (menu>tools>AGPS Data>Load). Check the time, for example with the ClockSync program (check several times, look typical deviation, and then click synchronize - how to use the program and where to get it - see earlier in the article on time calibration). Let's go to engineering menu, LocationBasedServices, select “GPS” in the menu, and press the “GPS” button (the inscription on it will change from OFF to ON). Go to "View". We wait until the “fix” appears (the GPS indicator stops blinking), and then for at least another 2 minutes. Then click RefPosition, and in the windows that appear, enter the coordinates previously written out from Google Earth for the point where you are calibrating (there will be zeros there). Click "OK". Go to the View screen again, and wait after the "fix" for at least 2x minutes, preferably 5 minutes. We go back to the engineering menu. If step 3 was not performed, simply choose any fairly open place. Taking out- don’t even try to do the calibration on the balcony or “from the window” - you’ll only make it worse.
    5. ****You can also check the correctness of your choice before calibration SIM cards for AGPS - if your mobile operator“glitchy”, and there are two cards and two operators, then you can choose a less buggy one, this, if “buggy” was selected, can significantly speed up GPS operation, and then “revive” the “completely broken GPS” procedure is described at the very end of the note.
    6. Go to the "Engineering Menu"(for my FLY IQ 450 and many Chinese clones, this is the code *#*#3646633#*#*, which we dial where you usually dial the phone number when calling, you may have a different one). Find "YGPS location" and launch it. Hold your phone vertically.
    7. Go to the Information tab. Click the "Full" button.
    8. Go to the "Satellites" tab, wait until at least 5 satellites appear (preferably more - I had 11 of them when setting up), and after they “appear and turn green”, wait at least another 2 minutes, holding the device motionless (it can be longer - it won’t be worse - only better ). This is the initial calibration. It took me about 3 minutes, but for some devices, according to reviews, it can take up to half an hour.
    9. Go to Information", click "Cold". Continue as in point 8. Repeat point 9 3 times. More is possible.
    10. Back to Information. Click "Warm". further as in paragraph 8. There is no need to repeat it anymore.
    11. Back to Information". Click "Hot". Continue as in step 8.
    12. If you followed step 3, go to the engineering menu, select the "LocationBasedService" item, go to the "View" tab (remember to activate GPS as described in step 4), and wait until the maximum satellites are determined. Minimum 7, better more (the more, the more accurate the calibration), and after the maximum is determined, wait another 2 minutes. Then go to the tab GPS, and click "RefPosition". You will have two numbers, from the one you previously recorded using Google Earth, they will most likely differ in thousandths. Correct both to those that you wrote down earlier in step 3. Click "OK". Now go to the GPS tab and wait for 5 minutes holding the phone motionless. Here in this place - the longer the better. GPS program, having received real coordinates, compares them with those that she “obtains” and makes corrections. clarifying them. Below in the window you will see a “process” counter and data that changes from time to time.
    13. Exit the engineering menu and reboot the phone.
    14. All. We rejoice in the fast and accurate GPS.
    After a fully executed instruction, the actual position accuracy (calculated from google earth and not the one shown by the GPS itself), was ~2.3-2.5 meters (GPS showed an accuracy of 5-6 meters in status), with 9 satellites “visible”, and 8 meters (GPS showed an accuracy of 10.5 meters in status) with visible 7 satellites - the satellites move and do not happen from time to time in the sense of day to day.

    PS If you are also going to use the program described here: http://vyacheslav.blogspot.com/2013/07/android-gps-6.html, then keep in mind that you need to calibrate it after installing it. And if it is uninstalled, calibrate it again - it resets the calibration data during uninstallation, and the GPS again starts “searching for satellites for several minutes.” Loading its “acceleration” data does not SEEM to affect the calibration, but it also makes no sense - the difference in speed is “within the limits of statistical error.” But it seems that the real accuracy is a little better, with freshly downloaded data (by 20 percent, but also within the statistical error in essence). Also keep in mind that the downloaded data from the above program quickly becomes outdated, and after a day or two, on the contrary, it will slow down the GPS and reduce accuracy (compared to a simply normally calibrated native one using the method described above in this article). Plus, I took it down nafik :) Bo, firstly, is not needed, and secondly, with it you can get “GPS which does not determine anything” if you forgot to download new data. Even if you clicked the “reset downloaded data” button and do not launch the program itself. At least this happened to me once - I didn’t check the rake again.

    PPS There are rumors on the net that “turning on EPO data” (specific GPS data for MTK chips), which gives some acceleration of the “cold start”, reduces the number of “captured satellites”. This is unlikely. The number of satellites captured is determined by their "number overhead in at the moment"and height above the horizon (in the city, those that are above the horizon are usually not visible). But even so, when calibrating, it is better to turn it off. And use it only if you are going to a place where the Internet may not be available. Then it will give you a real startup acceleration (it downloads data a month in advance) In a normal situation, it is better to use only AGPS - its data is fresher, and therefore more accurate, so the “start” speed with it is typically higher.

    PPPS Below is “reference information” for those who received a device with a completely non-working GPS. It’s worth checking it - the reason may be that you have something different from the following listed in your settings:

    In the engineering menu, in the LocationbasedService item, in the AGP tab S:

    Enable A-GPS, MSB, User Profile, SLP Template - GOOGLE, supl.google.com, 7275, TLS Enable, RRLP, IMSI, K-Value must be enabled.
    Horizontal Accuracy - 22, Vertical Accuracy - 0, Location Age - 0, Delay - 0. Location Estimate is selected.
    *********Selecting a SIM card for AGPS
    Go to the NET tab - select - click look at the map (Map tab), the address where you are located, or close to it, should appear there. We do the same with . We compare what is more accurate to yours real situation, and on the AGPS tab select your preferred SIM card.
    On the AGPS tab, click
    Yes, if any of the things listed in this PS differed from the settings of your device, or if you changed the SIM card to which you have AGPS attached, you need to perform a new calibration.

    PS About the influence of clock accuracy on the GPS cold start time.

    From the “inconvenient place” - a balcony, everything on top is covered with concrete, a courtyard-well - houses on 4 sides, the sky is a “piece from above”, 4 satellites are barely visible (then you can barely see 3, and the 4th one appears and disappears). The phone was calibrated according to the method outlined above (before calibration, there was no capture at all under these conditions). The clock “lags” by ~160ms (2 hours have passed since the clock was calibrated by the ClockSync program). Cold start time ~250-300 sec. After forced time calibration by the ClockSync program, the “cold start” time is ~100 seconds. However, these are the conditions. in which GPS usually does not work at all, but clearly illustrates the influence of clock accuracy on the “cold start” time.

    PPS To force the loading of AGPS data, for example, if you are far from the place where they were downloaded - for example, you went 200 kilometers for fishing/vacation, etc., and the AGPS data downloaded at home has become irrelevant, which can negatively affect the “cold start” time.

    You can use the GPS Status program from here: https://play.google.com/store/apps/details?id=com.eclipsim.gpsstatus2&hl=ru. Launch this program. At the bottom left under the “coordinate circle” is the age of the AGPS data in hours. Click Menu > Tools > A-GPS Data. Then "download".


    Almost everything modern smartphones equipped with a GPS chip. The navigation module is present in most tablet computers operating under the control of the operating room Android systems. However, not all users know that the chip is often disabled by default. As a result, such people are surprised that there are no geotags in the photographs, and the service Google Now does not show the route to the house. Fortunately, you can enable GPS on your tablet and smartphone without any effort.

    Why do you need GPS?

    Decades ago, GPS satellites were only available to the military. But the Americans quickly realized that big money could be made from navigation chips, applications and maps. As a result, access to technology was gained by ordinary people- all you had to do was acquire the appropriate device. Initially, these were specialized GPS navigators. And now the navigation module has seriously decreased in size, and therefore it can be built even into an ordinary smartphone.

    GPS signal helps to understand at what point globe you are now. This is useful for several reasons:

    • Navigation app will help you not get lost in the forest;
    • With navigation you can navigate even in an unfamiliar city;
    • You can easily find the address you need;
    • You escape from traffic jams - the “Traffic” service helps you avoid them;
    • Various applications show you nearby eateries and shopping centers;
    • GPS helps determine your speed.

    In short, a navigation chip can be very useful. But you will have to pay for using it. If you decide to turn on GPS on Android, then get ready for higher power consumption. This is most noticeable on older devices where there is no support A-GPS technology. Also, inexpensive and older smartphones have problems with reception GPS signal. Ours will help you get closer to solving it.

    GPS activation

    But enough of the lyrics... Let's find out how to turn on GPS on your phone under Android control. This is done very simply:

    1. Go to the device menu and tap on the “ Settings».

    2. Here select “ Location».

    3. Click on the item " Mode».

    4. Select location mode " According to all sources" or " By GPS satellites ».

    Please note: On Samsung and some other smartphones, the item names may differ. For example, the section " Location" may have the name " Geodata».

    If the navigator is on operating system Android doesn't work, don't despair; many car owners have encountered this problem. This does not happen because the system is unreliable; it can often be due to a number of internal reasons for the device. The main task is to find out why the device does not work, to identify main reason and find a method to eliminate it.

    The navigator on Android does not work, what is the reason?

    Availability of modules GPS navigation there is no surprise in modern smartphones. This addition is often used by users for walking and cycling. This is extremely convenient, especially when traveling, when tourists wander through unfamiliar city streets and simply cannot find their way to the hotel. That is why users, when choosing an Android smartphone, prefer gadgets with a built-in GPS function.

    If on mobile device The navigation system does not work, the problem can be simple to the point of banality - the navigation module itself is disabled. However, this problem makes users who have not fully understood the capabilities of the device nervous.

    Important! In order to configure the operation of the device in this case, it is enough to lower the curtain, which hides the necessary screen settings icons, the clock and the notification panel.

    In the menu you need to find the “Geodata” item and activate it with a simple click. The icon should change color to blue, green, or orange, depending on your color scheme settings.

    After performing this simple manipulation, you can try to launch the navigation program and start using it.

    Fact! Some applications specially designed for Android can notify the user that the ability to receive geodata is disabled. This feature is necessary because it will help the user promptly identify the cause of the shutdown and change the settings in the settings.

    This is exactly how it goes convenient application"Navitel" which, after disabling geodata, prompts the user to correct this parameter in the navigation menu.

    The navigator does not work: common reasons

    If reception of geodata is enabled, and all necessary for full-fledged work applications, but the navigator on your Android smartphone still does not work, you need to look further for the reason. The absence of any changes may be due to user impatience; usually, to ensure a full connection, the device requires certain time, about 5-15 minutes. During this time, the gadget downloads and processes information about the satellites available within the area, and establishes its own location.

    Attention! The user should not worry, all subsequent launches will not take so much time. This happens only for the first time, similar to the cold start of navigators.

    Using the same principle, you will have to download the device if you move to another region of the country. This is due to the fact that the device requires some time to establish its own geographic location and identify available satellites.

    Among the common reasons why the navigator may not work well are the following:

    1. Attempts to start while moving in a car. Some devices tend to “slow down”, so they require some time and immediate calm to start.
    2. The navigator may not function when you are indoors.
    3. The navigator may not work well in closed areas: under the canopy of trees. To establish communication, you need to find a suitable area.

    If the listed manipulations did not help restore the device’s functionality, although up to a certain point the function worked normally, most likely the cause should be sought in an internal failure of the device. Do not attempt to disassemble the device yourself. It is unlikely that it will be possible to establish the fact of a failure, but such actions can significantly aggravate the situation; it is better to take the device to a service center. In some cases, to restore functionality, it is enough to reset the settings to factory settings - if the reason lies in the conflict of any programs or failures software.

    Firmware as a reason for navigator failure

    If it is impossible to identify the problem with the naked eye, the best option is a firmware change. This procedure is quite simple and can be done by regular user smartphone. Information for the firmware is entered onto a memory card, which can be placed in the navigator. After this, the device is turned on, and by holding the key, you need to wait until the information about loading the software is displayed on the screen. If the device operates on Android, its logo should appear.

    It is important to pay attention to the main points:

    1. Some manufacturers do not make the firmware publicly available, so you won’t be able to reload the software yourself. To carry out the manipulation you will have to contact a service center.
    2. If the device is under warranty, replacing the software, as well as other interference with its operation, will void the possibility of free repair.

    Very often, a malfunction of the navigator on Android occurs when it is necessary to replace the firmware. Users need to remember that despite the apparent simplicity of the actions, they should be careful when downloading. Before updating, you need to charge the phone and scan the memory card using an antivirus program.

    All modern smartphones and most tablets are equipped with a detection module GPS locations. GPS “lays out” routes through unfamiliar areas, can determine your location with an accuracy of several tens of meters, and also automatically launches some programs or turns on reminders in specific places. Perhaps the only disadvantage of GPS is that it drains the battery of a smartphone (tablet) very quickly. Before starting GPS, let's figure out how to properly configure its operating mode. Let's take a closer look at how this can be done, and also explain how to configure GPS using the engineering menu in case of incorrect operation.

    Modern devices combine the functions of several devices at once

    Setting the GPS operating mode

    GPS is enabled in the notification bar. It is indicated by an icon that resembles a needle. You can determine the operating mode by going to “Settings - Personal data - Location - Mode”. The system will offer you three options: “High accuracy”, “Battery saving”, “By device sensors”. In newer Android versions they can be called: “By all sources”, “By network coordinates”, “By GPS satellites”. Let's figure out what's behind each of them.

    1. "High precision"(“According to all sources”). The most accurate, but at the same time the most “gluttonous” mode. Determines coordinates by all available means: GPS, Wi-Fi and using . The space is constantly monitored for the presence of a signal, determining the location both in open areas and indoors. This mode is also called A-GPS. If conventional navigators pick up signals exclusively from satellites, then not every smartphone and tablet is capable of this. Additional service information, downloaded from World Wide Web, will significantly speed up search and communication with satellites.
    2. "Battery Saver"(“By network coordinates”). Uses only wireless networks- GPS module is not enabled. In this case, the accuracy of determining coordinates decreases somewhat. Indoors, the location is determined quite accurately by Wi-Fi signal, online mobile operator- by radio tower signal.
    3. "By device sensors"(“According to GPS satellites”). This mode only works in open areas - the location is determined by the satellite signal. Indoors, the signal is lost, and the location, accordingly, will not be determined.

    For optimal battery consumption, you should select the “By device sensors” mode and turn off location detection in the notification panel. If you need to get directions, then you turn on location determination again and follow the instructions of the navigator. If you want to have one, and you are not bothered by slightly increased battery consumption, then select the “Battery Saver” mode. If battery consumption issues do not bother you, and you like it when the system determines your location with an accuracy of up to a meter, then your mode is “High Accuracy”.

    Setting up GPS through the engineering menu

    Flawlessly working GPS module (satellite search, fast connection to them, a stable connection with them) greatly simplifies life, especially in those moments when you are moving through unfamiliar terrain.

    But in Chinese models, running on the MTK processor, with long work GPS connection may be unstable, in the worst case, the location may not be determined at all. This is all due to the fact that the module is not configured quite correctly to work in our latitudes.

    In order to correct the operation of the GPS, log in where you will have to make a number of simple settings. We would like to warn you that you will perform all actions at your own peril and risk.

    So, the device must receive superuser rights (also called Root).

    1. Turn on GPS and Wi-Fi and go out onto the balcony, or better yet, to any open space.
    2. Enter the engineering menu. To do this, enter the combination *#*#3646633*#*#, or *#15963#*, or *#*#4636#*#* on the keyboard. It may differ from the combination for your smartphone (tablet). If none of the listed combinations work, download the Mobileuncle ToolHero program and select the appropriate menu item in it. The program itself is Russified, but the engineering menu is in English.
    3. In the program menu you will see several bookmarks. Scroll to the left, select the Location tab, and go to Location Based Service.

    1. In the EPO tab, check Enable EPO and Auto Download. EPO is system file, containing information about the coordinates of the satellites and their flight path. This item is not active on all devices. How to download EPO can be found on specialized Internet forums, for example, http://4pda.ru/forum/index.php?showtopic=466241.
    2. Go back to the previous level and select YGPS. In the Satellites tab you will see a diagram with the location of the satellites. They will all be red. This suggests that the gadget sees them, but due to incorrect settings cannot connect with them.
    3. Go to the Information tab, click full, then after a couple of seconds AGPS restart.
    4. Return to the Satellites tab. After a few minutes, the tablet will connect to the satellites and the dots will become green. Note if GPS settings If you are working out on the balcony, then your device may still not connect to some of the satellites. This occurs due to signal interference.
    5. Reboot your device. Now the signal from satellites should be picked up much faster and more reliably.

    Conclusion

    Nowadays you know everything about the operating modes of satellite GPS module on an Android tablet, and in case unstable work you can customize it.

    We will be very grateful if you share your feedback on the material or add valuable additions regarding the operation of your particular device model.

    On Android based does not determine / does not determine 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 after this the problem is not resolved, see Method 2.

    Method 2.

    Based on solving problems with communication and network reception phone number and tablet based Android method implementation of 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. Best monitors system functions, adjusts, and fixes everything possible errors settings and synchronization is small and easy to use, free utility for Android devices. Download the app from Google Play and watch it additional options in the description it is possible . 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.)
