System code phone number. Application of Android service codes

Lock cell numbers Any operator occurs on the same scheme. Differences concluded except in the content of the commands that are sent through a special service located on the official website of the operator providing communication services.

Three whales"

There are several dozen in Russia mobile operatorsBut only three of them are the largest service providers. The leader in the number of subscribers is the company "Mobile TeleSystems", in second place - MegaFon and closes the Troika VimpelCom Leaders (Beeline). Since these three operators are headed by a list of the most popular companies, focus on how to conduct them to subscribers.

Algorithm Locking

How to block the phone number via the Internet? The first step will be the same for owners of any SIM cards. First you need to go to main page of that operator cellular communicationwho provided you with a service. The menu should find the service management service via the Internet. The service name may differ from other companies. For example:

mTS on the site has an "Internet assistant";
"VimpelCom" subscribers are available "My Beeline";
megaFon users can use the "Service Guide" section.

To start the locking process, you must first access the personal account management. And here for each operator there is a password option.

Those who are the owner of the MTS SIM card, you need to dial a combination on a cell * 111 * 25 #, and then press the call button. For those who have not coped with this task, a second option is provided. Call on free room 1115 and enter a pre-invented password. It should not be shorter than four and no longer than seven characters.
Users of services provided by Beeline, you need to dial the * 110 * 9 # command, confirming the entry with the "Call" key. After that, within a few minutes, your mobile should come to an SMS message in which the password will be specified to enter your personal account.
For those who use MegaFon's services, the following set is relevant: * 105 * 00 #, also reinforced with the call button. The password comes in the message.

What to do next?

After the password is obtained, you need to fill in the "Login" and "password" fields at the entrance to Personal Area. In the first, specify your phone number without eight, and in the second - enter the resulting combination of characters.
As soon as the service functionality is available, select the "Lock" item in the menu, indicating that you block the phone voluntarily. Next steps The system will prompt itself.
Lock completed. The SIM card will remain in an inactive state until you decide to unlock it again.

It is important to remember that after a certain period of inactivity of the card, the operator has the right to re-re-enter the number to another subscriber, it is better to periodically unlock "SIM".

If you stole an iPhone?

It is one thing if you have to block a SIM card for personal reasons. It's completely different if the gadget was lost or, even worse, stolen. Lost Iphones are rarely returned to the owners voluntarily. Therefore, when discharge is discovered, the first thing you need to block the device.

For mobile devices of this type there is even special application "Find iPhone". You can only use the Internet. How to do it?

Go to the iCloud.com resource, enter the Eplidei and password. Do not rush, the main thing is to enter the input as correct as possible.
After logging into the system, we are looking for a missing thing on the locality map. Loss location will be highlighted in green. Click on the appeared beacon.
After confirming the location of the device, a label with the letter "I" will appear on the screen. By clicking on it, in a special window you can specify the cause of the lock - the loss.
Further from you will need a password generated by the system and confirmation. Password is better to record, because unlock the found iphone can only with it.
We write your contact number The phone is, it will be seen on the display of the lost iPhone those who will seem to find a loss. You can make a small appeal.

Important! You will not be able to block off the iPhone, as this feature is available in remote mode only when the device itself is connected to the Internet. If the phone found intentionally disconnected, it can be waited when it is turned on to quickly block the device. Do not forget to contact the police with a statement about the loss of expensive devissa.

Smartphones (Samsung, HTC, Motorola, Sony, LG, Lenovo and others) with Android (6.0.1, 6.0, 5.1, 5.0, 4.4.2, 4.2, 4.1.2 and others) have secret codeswhich displays hidden functions.

They allow anyone who knows about them to get to the operating system on a much deeper level than is allowed to ordinary users.

Such rear doors allow developers (third parties) to create additional functionality In their programs and applications.

Special hidden codes (backdors) are also used to solve problems in smartphones, while other modes are not available, for example, were blocked.

Knowing such access to hidden smartphone settings can be very useful if you know how to use them.

On android smartphones, there are always several secret codes, thanks to which we have access to hidden functions and information not available in the operating system menu.

Special codes are a sequence of rows and numbers, to access a hidden menu where you can change the basic parameters of the device and system.

They were used even in old models of phones before we came to the era of smartphones.

Special codes in android

Most of these codes are common to most of the versions of android and mobile devices.

All codes are entered using the keyboard on which you dial the phone number.

Hidden functions are also largely dependent on the manufacturer and there is no guarantee that they will work on all models of smartphones.

You can try their effect on Samsung, Lenovo, HTC, Motorola, Sony and many others.

These codes are generated by Android developers seeking to correct the complex problems faced by android devices.

Thus, these codes helps users manage their device using a combination of characters and numbers written on their set section where operating system Automatically starts a predefined effect.

What can android secret codes do on a smartphone

Hidden secret codes give you a chance to learn your phone or tablet better and make certain changes.

You can get information about the device and make a lot of things. That's which of them.

Reset settings
Erase all data
Reinstalling phone firmware
Test Screen
Check product code
Check the status of the battery and many other ingenious things.

Engineering menu opens access to manual setting "Iron" part of the smartphone. You need to enter a special code or install an application, but there are a number of features that you should pay close attention. If you could not enter the engineering menu from the first time, then did not take into account the features of the device. It is necessary to immediately clarify that any interference with the operation of the device can lead to its inability and loss of warranty.

Hidden system capabilities

In the last stages of the smartphone setting, the developers test the system for errors and check the operation of all device sensors. Especially for this in Android, a special subprogramme is sewn - an engineering menu that provides access to hidden settings Android OS and allows you to reconfigure them yourself. In addition, the menu is deployed device information. The full list of menu features is known only to the platform developers, so your changes should be made with caution.

Secret trails of developers

To enter the engineering menu, type the code * # * # 3646633 # * # *. On some models, you must additionally press the call key. It is worth considering the features of phones: for different brands There are various combinations of numbers. Android version Does not affect the engineering menu functionality.

Enter a special code to enter the engineering menu

If there are no problems, you will fall into the additional menu for fine-tuning smartphone.

We enter the subsection menu

Depending on the system version and processor model, the engineering menu can be incomplete or absent. In the photo above, the menu subsection with the test elements of the smartphone sensors, the USB connection setting, the execution of tests of internal and external memory.

If the first time did not work

Not all devices are included in the engineering menu. Consider a number of common problems and ways to eliminate them.

Android is a complex operating system based on UNIX. If something does not work, you did not take into account all the nuances of the functioning of a subprogramme.

List of special codes

One of the common reasons for blocking the entry into the engineering menu is the wrong special code. The combination of numbers depends not only on the device model, but also from the processor type. For example, most of the MTK chip database devices are equipped with an engineering menu. If we talk about Qualcomm, far from all smartphones on the basis of this platform sewn engineering menu. The list of combinations is shown in the table. If you did not fit the desired, try entering another combination.

Table: Code options for different Android models

Engineering menu do it yourself

If no special code approached, do not be upset. There are many applications with an engineering menu functionality. It is worth noting that the MTK attack in the names eloquently talks about compatibility only with MediaTek processors.

First option - MobileUncle MTK Tools. In this program, in addition to the necessary set of settings there are several additional features: Firmware update, Recovery update, GPS receiving mode and more.

MobileUuncle MTK Tools provides settings

Another program is MTK Engineering Mode. The program completely repeats the regular engineering menu.

MTK Engineering Mode repeats the regular engineering menu

For those who have a device not equipped with an engineering menu, there is another option: the installation of third-party firmware. In assemblies of third-party developers, there is very often a wide range of "Underway" settings.

Where to begin

When you first enter the menu, you can get lost in the rapids of the parameters.

Settings for engineering menu

Settings open huge opportunities for users.

Depending on the hardware platform, some items may not be available or absent.

In this section, you can configure the parameters. mobile communications.

Setting the volume of speakers

In the subsection, you can configure the overall volume level, the volume of headphone playback and speakerphone.

A change in volume parameters should be treated carefully. All parameters are individual for specific model Devices. Incorrect configuration It may lead to the deterioration of indicators of hearing.

There are a number of common parameters:

MAXVOL - the overall volume level. Range of values \u200b\u200bfrom 0 to 160. Than more Number, the higher the volume.
SPH - Volume when telephone conversation.
MIC - microphone sensitivity.
Ring is the speaker volume with an incoming call.
Media is the volume level when watching movies, listening to music and games.

Very often, users are dissatisfied with the volume of the speaker when talking. To improve audibility, go to the Normal Mode menu and change the SPH parameter to 150. If the phone is quietly called with an incoming call, then you need to increase the Ring parameter value. We advise not to put the value above 200, this may lead to the output of the dynamics. To be better audible, change the MIC parameter from 100 to 172. This will increase the sensitivity of the dynamics.

Root - Panacea for smartphone

On a smartphone without root rights, the functionality of the engineering menu is limited: some items are not displayed, the changes made are not saved. For any intervention in the work of the smartphone required open access in the system. Do not forget that getting root access can harm your gadget, the warranty on the device is canceled. We strongly recommend backup important information On the memory card and to synchronize with Google Account and remove it to avoid data loss. For unlocking full access You can use one of the existing methods.

Installing the application directly to the device (Kingroot)

SUPERSPUTER Access can be opened with a smartphone using special programs. Consider the sequence of operations on the example of the Kingroot program:

After that, you can safely change the parameters in the engineering menu, all changes will be saved. In the case of a negative result, we turn to the following method.

Obtaining superuser rights through PC (Kingo root)

This method is distinguished by a little large quantity Preparatory Activities:

The engineering menu is used to configure the device and test the work of the Iron Filling. This is a sewn system subprogramme, which is an indispensable tool as for experienced usersand for beginners in the world of mobile devices. However, it should be noted that the manipulation with the engineering menu can lead the gadget into a non-working condition.

Today, the device's market for android platform huge and occupies a significant part among mobile gadgets. Installing special plug-ins and supplements can significantly expand the capabilities and so the functional platform. Therefore, Android smartphones contain many information about the system and technical equipment, which is hidden from the eye of ordinary users. It often happens that manufacturers limit any functions of the device at the program level in order to restrict access to users important settings System kernels. In an example, you can bring the low speaker volume when calling, which is often found in many models of smartphones.

Most users of smartphones and Android tablets are not suspected of the existence of codes for android, which is called secret, service or engineering. Such codes appeared much earlier than the platform itself and were used on simple mobile phones. With the help of such codes, you can painfully interfere in the software shell, control those or other functions of the device. Secret codes for android may be useful in some situations, such as receiving additional or hidden information about the smartphone, full reset settings, hardware testing, formatting, etc.

However, using these service codes is with extreme caution at your own peril and risk, because Some changes made by entering codes are irreversible. Using secret codes does not affect the device's warranty, because These codes are provided by the manufacturer and use the engineers in service centers When repairing.

All secret codes are introduced using digital keys In the dialer. Before using any code for Android carefully read its description. Using these codes, you can get a lot useful information Simple way to your device.

For the convenience of perception, we broke the codes by groups by combining them in a logical purpose.

Built-in applications.

Combinations in this group allow you to run embedded applications.

*#*#0588#*#* - Start the integrated motion sensor.

*#*#273283*255*663282*#*#* - Starting built-in file Managerwith which you can do backups files.

Receiving the information.

*#06# - Shows IMEI device number. Knowledge IMEI numbers It is useful if the smartphone is lost or theft, it is from it that any mobile operator can track the current owner of the device. If a smartphone with two SIM cards, then two IMEI numbers will be displayed.

*#*#0283#*#* - Displays information about batch data.

*#*#2663#*#* - Shows the version of the touch screen.

Service functions.

*#*#7594#*#* - Setting the device power button. With a long to hold the power button, the menu is shown with action options (turn off, restart the device, turn on the flight mode, etc.), so this combination allows you to make changes to this menu.

*#*#7780#*#* - reset the device settings to factory, while resetting the settings will not touch installed applications and information on the memory card.

*2767*3855# - Reset the firmware of the device to the factory state, erases all the information. Operation cannot be canceled.

It is worth noting that not all of the above combinations will work on your smartphone, since the performance of the codes may depend on the manufacturer of the device. Using secret codes for Android can help you with a smartphone setting up or checking some of its functions for performance.

Codes descriptions can be downloaded from the server if there is a connection to the Internet, as well as contribute by writing your description of the combination.

Remember, working with android codes, you must realize that some combinations can lead to irrevocable destruction of the information on your device. We are not responsible for all the consequences that can happen to your device after using the above combinations. Information is provided for familiarization.

Service becomes useful in cases where the user needs to access some functions that are not available in as usual mode. By and large, they were invented to test the device, but we can also use them to call various menus.

Advanced users constantly have a matter with them. For example, on some Galaxy devices, you can adjust the volume of the sound, find out the hidden information about the phone and much more. Now we will analyze the most useful service codes that will suit users of smartphones and SAMSUNG tablets.

How to enter service code?

Everything is very simple. Open the dialer and enter numbers with signs that the corresponding menu you want to perform. After entering the last symbol, the menu should automatically start, no additional action is needed.

Denial of responsibility: this information is intended for experienced users. Do not try to change anything in the settings if you are not familiar with mobile devices. We are not responsible for the problems that have subsequently arose, including data loss or hardware damage.

All service codes for smartphones and SAMSUNG GALAXY tablets

I repeat that you should not touch the parameters that you do not know. You risk losing your phone functionality or valuable data.

Useful key combinations for Samsung Galaxy

Log in to the recovery: In the off state of the phone, clamp the volume button up, home and power
Bootloader / FastBoot mode: You also need to turn off the phone, and then clamp the volume buttons down, home and power
Create a screenshot: on the desired screen Press the volume up, power and, of course, the home button.
Make the phone Go to the off state: simultaneously hold the Volume button down and power.

We hope these system codes and key combinations will be useful to you, but, as in the 100th time we want to warn you that it is worth using them in double caution.
