To date, the Android operating system is maximally adapted to the needs of the modern user. A wide range of settings and functions will satisfy almost any request. And yet sometimes it seems that this is not enough, and I want to expand the functionality of the gadget. It is such an opportunity that the engineering menu gives. In this article you will learn how to configure the engineering menu and what it is.

How to enter the engineering menu android

The engineering menu is a special program with which the user can make adjustments to the operation of the gadget, as well as carry out technical testing and evaluate the operation of the sensors.

There are several entries in the engineering menu. Namely:

• special Team - *#*#3646633#*#*
• brief versions of the team - * # * # 4636 # 15963 # *

If you failed to go through special codes or you have a tablet that does not support the number of numbers, you can download special applications.

• Mobileuncle Tools.

Enter the engineering menu, or as it is also called " Developer menu"You can not on all devices android. This feature is available only on gadgets with a central processor from MediaTek. On all other models it makes no sense to run the developer menu, because it is removed by the manufacturer. Even if the appropriate application is provided, then it is impossible to achieve workability from it, since the engineering menu is simply not in the device.

In addition, on modified operating systems, such as Cyanogenmod, the launch of the configuration menu is also unavailable. Initially, such systems were designed for models with Qualcomm processor, and they do not support the Android engineering menu.

Many users are wondering - how to configure the engineering menu. Setting functions allows you to use a one hundred percent device and makes it possible to solve several major tasks at once.

Among them:

• sensitivity regulation Dynamics and microphone
• reducing energy consumption
• reducing the time to search for satellites and scanning unnecessary ranges

You can familiarize yourself with the functionality of the engineering menu in the article of our site -.

Restoring IMEI through engineering menu

Quite often, with long-term operation of the gadget, various errors begin to occur, which significantly affect the work. This is subject to both global manufacturers and Chinese fakes. In order for the device to work correctly again, it is often recommended to make a complete reset of settings or reflash it.

More information about updates and pick up the firmware you can learn from our article. And to learn how to make a complete reset settings to factory values, you can in the article -.

After conducting such manipulations, the smartphone or tablet ceases to see the network. In such cases, it is necessary to check the device IMEI code. This feature is available in the engineering menu.

How to restore IMEI through an engineering menu you can read in our article Backup and recovery IMEI .

Resetting engineering menu

You need to change the values \u200b\u200bof the engineering menu, since incorrect settings can lead to incorrect operation of the device. Before changing something, it is recommended to write the source values \u200b\u200bto inspire yourself in case something goes wrong, and the new settings will lead to poor operation of the device.

If you did not write the original settings, you can reset the developer menu to factory. This is available on any MediaTek processor. Mandatory condition is the presence of root rights.

How to get root rights, you can read in our article How to get root rights to android , pick up your smartphone model.

Need to reset:

1. set Solid Explorer. or any other conductor
2. go to the root folder
3. further Folder data.
4. choose nVRAM
5. after entering the folder aPCFG.
6. found in it aPRDCL.

And already there you will find all the modified settings of the engineering menu. Sections can be deleted selectively. If you are not satisfied with the work, for example, Audio, then delete all Audio folders. After that, be sure to restart the device. After rebooting, the system will automatically create remote files with the standard parameters that are laid in the processor. If you want to completely reset the settings to zero, delete the folder aPRDCL.. After rebooting, it will be restored, and the phone will have factory values \u200b\u200bof the engineering menu.

Commands to access the menu

Commands to access the engineering menu vary depending on the manufacturer. There are also general commands for all Android versions, allowing you to configure individual device functions.

Main codes for entering the engineering menu

Entered commands differ for different brands of devices - select those that are suitable. It is not forbidden to check all - not the corresponding to the specific manufacturer of the team simply will not work.

Table: Commands for access to the engineering menu of various manufacturers

Commands provided by Google for Android OS

Android factory service codes, showing technical information about the device, often do not have bindings to the manufacturer. Basically, they are all "sews" in the default Android. The group "Numbering" teams is agreed by Google - on the rights of the Android operating system - with manufacturers of tablets and smartphones.

Table: Android factory service codes

When using commands, you must consider the following:

• updating the camera firmware through the engineering menu, you can learn about the version of this firmware and the number of its updates - as well as save this update to the image in the internal memory and on the SD card. Remove the camera is not recommended once again - in case of failure, you just turn it out;
• when resetting the Android system with deleting all user user data on the screen, a request message will appear on the need to confirm the reset.

How to enter the engineering menu

To get to the engineering menu, follow these steps.

What to do if it did not work in the menu

It happens that none of the teams intended for a particular brand of devices do not fit - this manufacturer protects inexperienced users from not to the end of thoughtful actions. Some manufacturers after the smartphone program debugging completely remove the engineering menu, and all the above commands simply do not work. For example, this makes Samsung. Some of the commands input can harm both the Android software and the device itself.

Often, instead of common service teams, more specific are triggered. If, despite all your attempts to "reach" to the engineering menu, none of the service codes is triggered - special applications are needed.

Install the free MobileUncle Tools application - it will distinguish hardware and system settings. It may be necessary to get root-access on Android. There are other applications: ENGMODEMTKSHORTICUT, BETTERCUT, etc.

How to Save Settings

So that the settings made using the Android engineering menu are preserved, you need to go out correctly. Being in any of the sections of the engineering menu, use the "Back" screen or in the menu itself, or press the Call Cancel button or the Back "below the display - it is indicated as an arrow with a reversal - to exit the level of the engineering menu.

It is not recommended by setting the value of any setting and confirming it with the SET key ("Set"), turn off or restart the smartphone by pressing the power button, pull out the battery from the device, etc. The output from the engineering menu can be pressed in the press - sometimes with hold For a few seconds - the same "Back" key, which is under the display. When you exit the engineering menu on the smartphone screen, a request message will appear about the need to save the generated settings - confirm it. There are tips on some of the sections of the engineering menu:

The reason why the engineering menu still does not save the settings may be "raw" firmware. Find out which version and build Android are suitable for your device. If you have a branded smartphone with the version of Android, which has pre-installed programs and components from Beeline, MTS, MegaFon or Tele2 - boldly establish a "custom" version, for example, a well-known CyanogenMod assembly. There may be any earlier - or, on the contrary, the most "fresh" version of Android.

In some cases, enter the engineering menu is impossible without getting root rights. The task is to make a smartphone with Android "rutted". In other words, get the "superuser" capabilities on the smartphone, allowing you to take a smartphone for the most clear and complete control. This is achieved in the following ways, use any of them.

1. Install on your smartphone custom (modified) version of Android. Its composition already includes the SuperUser software component ("Super User"), which opens access not only to the engineering menu, but also to the System system folder.
2. Load from Android Market any of the Android hacking applications without the help of a computer. Different programs are suitable here: Universal Androot, Unlock Root, Z4ROot, Revolutionary, etc., not all of them can help - have to test everything until it turns out.
3. You can also try Windows applications that do directly with PC all manipulations with root-access on your smartphone - for example, VROOT program. You also need a USB-MicroUSB cable - Wi-Fi hack Android on the smartphone is impossible.

After receiving the root privileges, the smartphone is ready to activate the engineering menu using third-party android applications.

The "Fresh" version - the more settings in the engineering menu will be in Russian. In the earliest versions of Android (1.x, 2.x), all service settings were in English. A little learn technical English, you can easily remember the purpose of each of the settings and if necessary, you can change them all in a few minutes.

The availability of the engineering menu is in whole or in part, it decides not the Android version, but the brand and model of the smartphone. Try different combinations and programs, but not too fond.

With ineptive actions or for the forgetfulness of the input codes, there is a risk of turning the smartphone into a lifeless machine, and only in the service center you can restore it. And since in the case of "rutting" of the device you automatically deprive the warranty.

Android engineering menu is one of the most useful tools of the "advanced" user who does not allow it to waste the hardware resource of its device and the resource of cellular and wireless networks is wasted. And no matter what your version of Android is 2.2, 4.2.2, 4.4.2 Kitkat, 5.1, 6.0 or other, the engineering menu codes are determined only by the manufacturer. Completely subdued to itself your smartphone or tablet, you will deprive it with "live your own life" not according to your schedule, but according to the script of the manufacturer itself, cellular operators and other intermediary companies, one way or another involved in the work of mobile equipment in cellular networks. This is the soastful way to professionalism.

Engineering menu Android and secret codes. What allows Android OS through the engineering menu to configure? Sound volume, sensors and more, read all this in our article.

Our smartphones carry a lot of secrets that are hidden by manufacturers. What do you know anything about the engineering menu on Android? And about secret codes heard? Once discovered our article, it means that something remotely, but heard. All of these tools appeared even at the birth of the first mobile phones, but that and naturally, over the years they became more functional and understandable.

However, it is worth noting immediately, the manufacturer's plans are not included in the engineering menu or secret codes on (which is understandable from the title) available to each wishes. And this makes sense. Let's go in order.

What is the engineering menu android, secret codes?

So, the ENGINEERING MODE is a special application that is installed almost to any smartphone. Used by a manufacturer for various tests and optimizing functions, sensors and other parameters of the phone or tablet.

By default, hidden in the system so that each user cannot access it. Called, as a rule, by means of a small code entered using a standard dialer. Thanks to wide opportunities, access to the engineering menu, and its control can be made using third-party applications.

Why is the engineering menu hidden? With careless use of the application features, you can harm your smartphone or another device. As noted above, an engineering menu is intended for manufacturers (developers, for tests). Therefore, it should be attentive, making any changes here.

Secret codes for Android (service, engineering) are somewhat different from the considered menu. If the engineering menu opens access to many parameters to many parameters, then one entered service code leads only to one, as a rule, functions. Codes are a lot.

And there is both universal (working on most Android smartphones, even mobile phones) and codes for specific models of devices. A little later we will analyze the most popular.

How to access the engineering menu on the Android device - codes

Android engineering menu - the most popular code

There are two popular methods: through a secret code or with a special software. Naturally, the first way is easier and more reliable, but not without nuances. Universal code, which will definitely transfer you to the engineering menu, not to find.

On one smartphone, one works on the other - the other, on the third - the third one. However, Android is not the first year, because the users of the most popular codes that are triggered on most devices are derived. So:

• # * # 3646633 # * # * - The most common login code into the engineering menu android menu;
• # 15963 # * # * - If the previous one did not work, try these;
• * # * # * # * # * # * # * # * - Used on smartphones from Sony's company; # 364647 # * # * - Used on smartphones from Sony;
• # * # * # * # 8255 # * # * - pay attention to the owners of HTC devices;
• * # * # * - In some cases, it works on samsung;
• 3845 # * 855 # - often used to access the engineering menu on Android smartphones LG;
• # * # 54298 # * # * - Works on many devices with MediaTek processor;
• * # * # * Or * # * # * # * - Huawei has its own set of codes. # 2846579

At least at least one, but should work on your device. The code is simply inserted by means of a dialer (phone application "on the desktop). As a rule, even the call button does not need to be pressed (not always) - at the end of the set, the service will occur. But not everything is so simple, there are certain difficulties of launching the engineering menu on some android phones.

It is impossible to enter the engineering menu Android: Causes

• first, in many smartphones or tablets with Qualcomm Snapdragon, Intel or Tegra or Tegra or the menu, or it is not possible to get access to it very difficult. In some cases, you can not even try.
• secondly, custom firmware may cause problems. In a number of them, there is simply no or blocked access to configuration tools. For example, the engineering menu you will not find in the CyanogenMod firmware, which is very popular among users. The reason is simple - initially the firmware was developed for Snapdragon database.
• thirdly, the source of problems can be the manufacturer itself who hid the engineering menu is more reliable or decided to remove it at all. Here we will take a different kind of mistakes, from which none of the devices are insured.

Actually, solutions to problems lie on the surface. If the smartphone is on Snapdragon, Intel or Tegra, then in most cases anything will not succeed. However, on these devices, you can access a number of hidden settings, which we will tell about which.

By the way, on Xiaomi smartphones, which for the most part are presented on the basis of Qualcomm chips, you can access the engineering, clicking several times on the "kernel version" in the smartphone settings (section "On the phone"). Finally, in some cases, refractming android devices on the stock (official) firmware will help.

In the second way to open access to the engineering menu can be applications. They are quite a lot, you can download free from, but almost everything is designed for smartphones based on MediaTek processor.

Again, it is not a fact that each of the programs will smoothly work on your device - there is a hundred reasons for which they will refuse to function. Small companies are engaged in the development of such funds, because you probably have to try out several.

What can be configured in the engineering menu?

Both the appearance of the interface and the set of parameters for configuration may differ for different smartphones. If you take the device on Qualcomm Snapdragon, then you often have everything you can do - look for information about various modules and make any tests.

Make any changes to the parameters will not work. But Smartphones on MediaTek offer much more features: sound configuration, network setting, various modules, and so on.

So, no matter what an externally engineering interface may differ on different devices, it will not be possible to deal with labor items. Let's go through the main possibilities.

Once again: Changes you put on your own fear and risk. Do not change the parameter values \u200b\u200bthat do not know anything.

Informative Opportunities for Android Engineering Menu

The first thing that the Android engineering menu offers is to explore various information about the device. It mainly concerns the network, wireless interfaces and batteries (on smartphones with Snapdragon processors by means of the * # * # 4636 # * command. What can be viewed in these sections:

• IMEI phone - a special (unique) room, which is assigned to each smartphone;
• Phone number - not always indicated;
• Network - denotes the current operator;
• Roaming - are or not;
• Network information - Consider or not, is enabled or disabled;
• Call redirection - is used or not;
• Network type, network index;
• Signal volume and your location in the form of coordinates.

In the "On Battery" section:

• Condition: Charged or not;
• Charge level (in percent);
• Tension and temperature;
• The technology on which the element is produced;
• Time with the last reboot.

One partitions allows you to view information about using applications on the smartphone (name, last launch date, duration). In addition, a separate section of the engineering menu on Android is dedicated to a wireless interface. Here you will find information about the connection status, the name of the network, you can find out the speed and some other data.

Testing the parameters of the smartphone in the engineering menu

Quite interesting engineering menu, allowing the tests of various smartphone parameters. Often helps to find the source of the problem, because of which the system functions incorrectly. What specific tests can be made:

• Complex (Automatic Test) - each parameter of the smartphone is tested;
• REPORT (report) - A test report is provided;
• Testing buttons, memory cards and SIM cards, vibrations, speakers, connectors - All this can be checked for performance;
• Screen tests - on brightness, sensitivity, and so on;
• Testing cameras and flash, flashlight, wireless interfaces and sensors (gyroscope, accelerometer and other).

Again, the set of testing options may differ. It all depends on the engineering menu of a specific android device. Undoubtedly, useful functions that will be useful to many users. For example, when buying a used smartphone, you can test the screen for performance.

Changing the parameters in the hidden menu Android

If there is nothing to be afraid in case of testing or studying information about the phone or tablet, then you need to make changes carefully.

It is better not to touch the parameters at all, the appointments of which we do not know, and also to make screenshots or marry everything that change. If you have any problems, you can return the options to the default values. Consider here the most interesting sections.

Cellular Configuration (Telephony) and IMEI Change

Engineering menu Android - frequency

There are focused installations to change network parameters. You can hardly remove the smartphone in order by changing these parameters, but you can break the network to break away, so you remember where you shoot and where to put ticks to in the future, if anything, return everything into place.

As a rule, changes in this section are produced in order to reduce energy consumption.

First, you can remove the selection from the frequency (subsection Band Mode.) on which your operator does not work. We find out what bands your cellular operator is running, remove the checkboxes from all the others. This will help slightly reduce energy consumption, as it will know for exactly what frequencies to connect it.

In the same subsection, on the contrary, you can include the desired frequencies. It is necessary when the manufacturer from the factory does not activate the necessary for your region. For example, often "out of the box" Chinese smartphones cannot work in Russia with LTE. This problem will help solve the service menu on Android.

Secondly, in the subsection Network SELECTINGwe can set the priority of networks that are used for access (2G, 3G, 4G). Everything is done for the same purpose: an increase in battery autonomous time. Typically, 3G and / or 4G networks are turned off. Not in each region there is support for these networks, and the communication module, as it may, continues to look for them, spending energy. Disconnected - and no problems. In addition, the device will not switch to 3G or 4G, spending traffic.

In subsection GPRS., we, simple users, are better not to climb if there is no reason for the reason. Here are the various settings for the work of the smartphone with the network, and there is an item to change IMEI.

Attention! There were precedents of criminal prosecution for illegally shift IMEI numbers. More often, the punishment is a cash fine, a suspended period. However, there were cases of real imprisonment.

The IMEI change function can be useful after an unsuccessful firmware attempt when the identification number "flies". Then you can simply rewrite it from the box in which the device is supplied.

Connectivity

Here, as in the case of GPRS, you have nothing to do. The section itself is designed to make changes to the settings of Wi-Fi and Bluetooth modules. The section will not be able to configure something that the smartphone works is better, but you can easily harm the electronic comrades.

Therefore, here we use only testing functions, and if you need to make any fixes to return the device to the working state, carefully study the purpose of each parameter on the network.

Sound volume setting in Android engineering menu (AUDIO)

Engineering menu Android - volume setting

Judging by the number of queries in the search, it is to increase the volume of the Android users resort to the engineering menu. Everything is simple enough:

1. Select the Hardware Testing tab -\u003e Audio. Select the right mode;

• Normal Mode - is responsible for the output of sound on the main speaker.
• HEADSET MODE - With it, the sound volume is adjusted in headphones.
• Loudspeaker - enter the settings for adjusting the sound parameters during speakerphone.
• Headset_loudspeaker Mode - allows you to increase or decrease the sound volume for speakerphone mode with connected headphones.

1. Now you choose from the drop-down list, for which device will configure the volume in the Android engineering menu;

SIP - options for Internet telephony. MIC - the sensitivity of the microphone is set. SPH (maybe two) - setting the speaking speaker. Media - multimedia speaker (main). Finally, an item that is better not to touch - SID. After the changes may appear echo.

1. In the LEVEL string, the volume level is set to each step (pressing) the volume of the volume. By default - 0. You can not touch if, of course, the sound on your device does not jump sharply when the button is pressed.
2. In the Value IS string, the value of each step (volume level) is set;
3. The most interesting line "MAX VOL", with which the maximum volume on Android increases through the engineering menu.

As a rule, the manufacturer of the smartphone is specified not the maximum value, so we can fix it yourself. Please note that at the maximum level there are raws of dynamics. To find the most comfortable value, go through options.

Secret codes for android

In addition to the engineering menu, you can use secret codes to access different functions. It is as difficult here to predict which of the commands will work on your device. Consider the most popular and useful:

*#06#	We get IMEI smartphone
*#*#232338#*#*	Learning Mac address and Wi-Fi data
*#*#232337#*#*	Shows Bluetooth address
*#*#3264#*#*	Displays information about RAM
*#*#1234#*#* ,	Learning all about the program part
*#*#2663#*#*	View Data on Screen Sensor
*#34971539#	Displays information about the installed camera sensors
*#0*#	Used for integrated smartphone test
*#*#0*#*#*	Useful for the test screen
*#*#2664#*#*	Runs the display sensor test
*#*#0842#*#*	Produces vibration test
*#*#0289#*#*	Come in handy for sound testing
*#*#1575#*#*	Runs Testing the GPS Module
*#*#7262626#*#*	Used to check mobile communication
*#*#7780#*#*	Reset smartphone settings - in whole or in part
#*5376#	Erases all SMS with smartphone
#*3851#	Will be suitable for rebooting the device
*#2263#	Setting network ranges
*#*#273283*255*663282*#*#*	Calling backup files

The engineering menu opens access to manual adjustment of the "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 the hidden settings of the 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 the 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 on 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 mobile parameters.

1. Auto Answer. Available on-off automatic response to an incoming call.
2. Band Mode. Allows you to select the frequency range for the operation of the GSM module. You will see all the technologies and frequencies for them supported by your smartphone model. If you wish, you can remove the checkboxes from the ranges that are not used by your telecom operator. This will significantly save the battery charge. To save the settings, press the SET button.
3. CFU Setting (CALL FORWARDING SETTINGS). The option enables or disables the conditional forwarding. It must be supported by the operator.
4. AT Command Tool. Utility for developers supporting AT commands. This menu item will be interesting for programmers and developers. With this menu, you can perform various requests directly to the system without visual add-ons.
5. Modem Test. Setting the compatibility of the "Access point" option with different types of connected devices.
6. Network Selecting. Here you can choose mobile standards (GSM, WCDMA, LTE). For additional energy saving, turn off unused.
7. NetworkInfo. Select one or more options to display information about the status of cellular parameters. After selecting, open the optional menu (three points on the right in the upper corner) and click Check information. This option is convenient to verify the quality of the cellular operator services.
8. GPRS. Setting the connection to the mobile Internet, select an active SIM card (if there are several of them).
9. HSPA info. Information about the 3G network in case of support by your mobile operator.

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 a specific device model. Incorrect configuration can lead to degradation indicators.

There are a number of common parameters:

1. MAXVOL - the overall volume level. Range of values \u200b\u200bfrom 0 to 160. The greater the number, the higher the volume.
2. SPH - Volume when telephone conversation.
3. MIC - microphone sensitivity.
4. Ring is the speaker volume with an incoming call.
5. 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, open access to the system is required. Do not forget that getting root access can harm your gadget, the warranty on the device is canceled. We strongly recommend making backup of important information on the memory card and synchronize with Google account and remove it to avoid data loss. To unlock the full access to the system, you can use one of the existing methods.

Installing the application directly to the device (Kingroot)

Suspector 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 more 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 for both advanced users and newcomers 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.

Acquisition of a new smartphone or tablet is a real holiday for many. Each owner expects a gadget for many years to delight with its reliable work and the lack of any problems. Moreover, regardless of who is the collector, and which control system is installed.

However, as often happens, modern mobile devices are difficult to call ideal, since after a while after the start of use, the moments that the owner wants to fix, in one way or another way to improve the program part of their mobile assistant to the ideal is revealed. Of course, in your understanding. One of the available tools is the engineering menu "Android".

Secret settings that everyone knows

At the final stage of configuration of the program component of a gadget running the system from "Google", the developers use the so-called engineering menu "Android". A special program that allows you to make adjustments to the operation of the device, perform technological tests, view information from the sensors. Since the thoughtless use of this tool can lead to unpredictable results, then most often access to it is hidden from users. However, in essence, the secret is already known to everyone - to learn how to call the mentioned menu, it is enough to pay only a few minutes to search for recommendations.

Several important points

Nevertheless, not all mobile devices can be logged in to the Android engineering menu. In order to take advantage of its capabilities, you need to make sure that the gadget meets certain requirements.

First, the central processor must necessarily produce MediaTek (or MTC). On low-cost Spreadtrum models, such as SC-6825, popular Snapdragon from Qualcomm, various Tegra Nvidia and Intel try to run the Android engineering menu is useless. It is absent there. It will not be possible to achieve workability, even if you prudently install the appropriate application.

Secondly, various modified operating systems, for example, a popular in some CyanogenMod circles, do not allow you to run the configuration program, as it was originally developed for devices with the Qualcomm processor that do not support the Android engineering menu. In addition, it is very desirable that the operating system is the original or created on the base basis.

Thirdly, the application itself (file) must be present among the programs, even being hidden from the standard conductor. So, some manufacturers of mobile devices After executing the program part settings, simply delete the engineering menu "Android". Description and recommendations for use in this case are useless, which is obvious.

Secret combination

You can get into the Android engineering menu settings in several ways. It is impossible to say which one is better because direct comparison is incorrect. Therefore, consider them alternately.

One of the most "ancient" options, which was still in the first models of smartphones and tablets, is that the user in the program-dialer (the so-called dialer) is not dialing the number of the subscriber, but a special code of the engineering menu "Android" by analogy with the verification funds in the account. If the combination is identified and accepted, then the setup application is launched. Some mobile device collectors use their own modified code, so the standard set does not always work. Otherwise, to call the menu, you should dial without spaces the following procedure for characters - * # * # 36 46 633 # * # *. That's it simple.

The usual way to access

The use of a secret combination is not always convenient, if only because the order of symbols is easy to forget. Also, in the case of a modified set, simply use the program, and not to look for the correct order of signs. One of the most famous applications is the so-called "Mobile Uncle", or MobileUncle Tools. It is free, so there is usually no problems with searching and installing. At the time of this writing, the actual version is official 2.9.9 or assembly 3.1.4, which has additional support for some new processors.

In order for the program to work, the user must first receive root-right on his gadget. To do this, there are a lot of applications, such as Kingroot, SuperSU, etc. In this article, we will not talk about the nuances of working with a rutted device, as this is a separate volumetric topic. After starting the application, select the third item called the ENGINEER MODE (as in Russian, so in English versions), and in the window that opens - "work with MTK". When a request for the provision of root access must be answered in the affirmative.

How to restore access to regime for engineers

If the manufacturer of the mobile gadget takes care of the safety of the operating system, prudently removing the configuration program, then it can be reinstalled. To do this, you need to find the installer on the network, restoring Engineermode.apk and install it.

We do not specify the exact name because of the abundance of analog clones. For example, one of them is called - "engineering mode". You can also simply copy the missing file to the system folder located on the System \\ APP path. After that, you can use in any way to access: both a set of number and direct call from the program interface. Note that these operations require

Opportunities miracle programs

Through the engineering menu, despite the ambiguous attitude towards this owners of gadgets, makes it possible to solve several essential tasks. In particular, adjust the sensitivity of the microphone, cure the "childish disease", manifested in the insufficient volume of the system speaker, reduce the energy consumption of the battery, turning off the scanning of "extra" ranges, and reduce the search time of the satellite receiver of the global positioning system. Let us dwell on the above functions in more detail, since they are most in demand.

Volume call

Raise the volume of the call is very simple. To do this, you need to choose the "Audio" section to the right. A list of modes will appear. Loudspeaker Mode is responsible for the system speaker, Ring subsection. The parameter in the first window should not be changed, but in the second you can register a higher value. The developers may be initially set by the indicator 130, which is rather quiet, and 156 is already close to the limit. Maximum is 160. After editing, you need to press the SET button here, and restart the device correctly from the program.

Frequencies of mobile operators

To optimize the power consumption of a mobile communication device, you can disable the scan of the "extra" frequencies. In our country, when working in ordinary 2G / 3G networks, 900 and 1800 MHz are standard frequencies. Another couple, 850 and 1900 MHz, is an American standard. To enable or disconnect, you need to select Band Mode, alternately go to the settings for SIM-1 and SIM-2 and remove \\ put the desired marks. The confirmation is pressed on the SET button.

How to improve GPS? To improve the work, you need to enable Wi-Fi, in the engineering menu "Android" select Location, proceed to Location Based Service and open EPO. Here you need to make sure that the checkboxes are at the items enabled and download (if present). After that, you should return to the YGPS and in the Information section alternately press "Full", "Cold", "Restart". Next, you need to select the "Satellites" item and wait until the answer is fixed (green points on the map). Everything takes from 2 to 5 minutes. After that, it remains to exit the menu, close the program and restart the gadget.

Summing up

The engineering menu of devices running on control opens the capabilities of which allows you to adjust the device in an optimal way. Often this is the only way to postpone the purchase of a new mobile assistant. This menu is contraindicated only to those who are completely satisfied with the work of the tablet, navigator or smartphone.
