Let's look at the features of the Android engineering menu various manufacturers, what it is for, how to use it and what useful functions this menu provides for you.

This article is suitable for all brands that produce phones on Android 10/9/8/7: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

Attention! You can ask your question to a specialist at the end of the article.

What is the Android engineering menu?

Engineering menu(Engineering Mode) is special application, which is available on almost every gadget. It is used by the manufacturer for various tests and optimization of sensors, functions and other parameters of a tablet or phone. This menu is hidden in the system by default so that the user cannot access it.

As a rule, the engineering menu is called up using a small code that is entered on a standard dialer. It can be accessed using third-party programs.

The engineering menu is hidden due to the fact that careless use of its capabilities can lead to damage to the device. Please be careful when making any changes.

How to enter the engineering menu on Android

A secret application cannot be launched through the regular interface. You can enter the engineering menu this way:

Open the calls window to enter a phone number using the keyboard.
We write a special combination of characters.
If immediately after entering the code this menu does not start, press the call button.

Each manufacturer has its own combination of characters, which contains special characters (*, #) and numbers. For example, for Samsung phones the engineering menu is launched with the following sequence: *#*#4636#*#*. The screenshot below shows the codes for different manufacturers gadgets.

If nothing happens after entering the code, use applications from Google Play that work with the engineering menu. For example, the MTK Engineering Mode application, which is a complete copy of the standard engineering menu. Most of them will require root rights to the device, without which the software will function with errors, and some parameters will be inaccessible.

Mobileuncle Tools

The program has advanced features. Can be viewed and edited basic settings, update firmware, restore IMEI and improve GPS signal. The utility displays full specifications memory, screen, sensor.

MTK engineering menu

Program for gadgets with MediaTek processors. Loads engineering functions successfully, but there are errors with saving parameters. They may reset after a reboot.

Recovery Mode

This mode for developers is useful when serious problems arise with the gadget. If your tablet or smartphone does not turn on, and you cannot get into the regular menu, you will be able to launch recovery mode.

To start, use the following combination: the power key and the volume down or up button. In some cases it is necessary to additionally press Home. Press and hold the indicated buttons until the download begins.

In this mode, the most useful section is wipe data. With its help it starts full reset, and the device returns to factory settings. You will receive a clean phone, and all data and applications will be lost. Resetting helps in a situation where you have gone too far with the changes in the engineering menu, setting invalid values.

Shortcut Master utility

The software allows you to work with shortcuts and system programs(creation, search, deletion). There is no function for direct entry into the engineering menu, but you can see a list with secret commands that operate on your gadget.

By clicking on the command name, the user is shown a drop-down menu with the “Run” option. The utility is convenient, no extra steps are required.

To see the list of codes, you need to call an additional menu in the utility. Then select the line “Secret code explorer”.

Root rights to enter the engineering menu

To enter the engineering menu in some versions of Android, the user needs to have . They can be obtained using specialized software: Romaster SU, UniversalAndRoot, Farmaroot, etc.

Instructions for obtaining root rights using Farmaroot:

Install and launch the software.
If the utility supports installing root rights on your gadget, then the “Get root” option will be displayed on the screen. Select this item.
From the preset methods for obtaining root, select one.
The software will begin installation.
After completing the procedure, a message will be displayed indicating the successful installation of root access.

Possible errors and solutions:

Root rights are not installed - try another method (select a new exploit in the application).
The application closed mid-installation. The user needs to restart the device and try again.

Engineering menu functions

The engineering menu is divided into several categories. Let's look at each of them separately:

Telephony. This category contains settings that relate to mobile communications. For example, you can disable or enable certain BandModes ( different frequencies for 2G/3G/4G operation), disable in background data transfer or check the operation of SIM cards.
Connectivity. Wi-Fi setup, Wi-Fi CTIA, radio, Bluetooth settings. In the settings you can specify the type of antenna (you must use headphones), radio wave, sound format (stereo or mono). The radio will play directly from this section.
Hardware Testing. Here you can configure the operation of various components of the device: sound levels of speakers and headphones, microphone, various camera parameters (focus, HDR, ISO adjustment, photo aspect ratio and much more), operation of sensors (calibration), touchscreen, etc. This category is quite global and large; you need to understand all sections and have skills and serious knowledge.
Location. In this category, GPS operation is configured, you can conduct testing, see the number of satellites found.
Log and Debugging. This category contains logs of the battery (charge percentage, temperature, operating time, voltage) and other functions that are little known to the average user.
Others. Contains two functions that are unknown to most users.

Engineering menu settings

Possibility of adjusting parameters and appearance The engineering menu may differ depending on the model of smartphone or tablet. Users in the menu change camera settings and apply recovery mode.

Volume Boost

If your gadget does not ring loudly enough, then in the engineering menu you need to find the Audio item and go to LoudSpeaker Mode. There we select the Ring tab. For all signal levels (1 – 6 Level) we change the values. The numbers are listed in ascending order.

In the Max. Vol. increase the value to the maximum. To save the settings, press the SET button.

Increasing the volume of a telephone conversation

To increase the speaker tone during calls, select Normal mode in the Audio service menu, then open the Sph section. For signal levels (1 – 6 Level) we set values from 100 to 150, and Max. Vol. – 160.

In the Audio menu you can increase the microphone sensitivity. To do this, select Normal mode, then Mic. For all levels we assign same value microphone sensitivity. Press the SET button, then reboot and check whether the interlocutor can hear you better.

Battery: disable unused frequencies

Phones quickly consume battery life running applications, network connections and maintenance cellular communications. Using the engineering menu, you can increase the battery life.

Modern gadgets scan GSM frequencies 850/1900 MHz and 900/1800 MHz. In Russia, 900/1800 MHz operates, so there is no need to scan the network at other frequencies. For the second pair, the radio signal can be turned off, which will save battery power.

Open the Band Mode section in Engineer Mode. There we turn off unused frequencies. To do this, uncheck the corresponding boxes: PCS1900 and GSM850.

When the smartphone supports 2 SIM cards, open the SIM1 and SIM2 items one by one, and then perform the specified actions in each. Press the SET button to save the settings.

If the SIM card and phone work in 3G networks, you need to disable the networks that are not used in Russia: WCDMA-CLR-850, WCDMA-800, WCDMA-PCS 1900. Press the SET button again. To enable scanning for networks that you have disabled, you need to return to this menu, then check the boxes.

Camera settings

On Android gadgets, by default, pictures are saved in JPEG format. Many photographers prefer to take pictures and process them in RAW format so that there are more editing options. The desired image format allows you to select the technical menu.

Find the Camera section in the menu, where we select “Capture Type”. Set the photo to RAW format and press SET. In the Camera section, you can set the ISO value, increase the size of pictures, enable HDR shooting for greater detail, and set the frame rate for video.

Secret codes of the Android engineering menu

In addition to the engineering menu, you can use secret codes to access different options. The screenshot below shows the most useful and popular codes.

Good time! Today our task is to find out what kind of program Engineer Mode is. I went looking for information on the Internet. There are first data. In general, Engineer Mode is an engineering menu that has a lot of settings, and it says that almost everything can be configured! Do you know what thought immediately came to my mind? Guys, there are a lot of settings, but it seems to me that you should only get into these settings when you understand exactly what you are doing! After all, this is an ENGINEERING MENU after all... not a joke...

You do not need root rights to open the engineering menu. You can enter this menu using the program, or enter a special code. I'm not sure guys, but it seems like not all phones have this menu! This menu is definitely available for phones that have an MTK processor, even have special programs for these phones such as ToolHero, Mobileuncle MTK Tools. In short, such a small hit, this menu is not available everywhere, keep this in mind...

Although it’s still a little surprising to me.. The fact is that I looked on the Internet and there many sites write that you can access this menu from many phones. In short, it’s not clear .. I found a picture and it shows what combinations need to be entered to open the engineering menu on different phones, look:

Well, if you have a phone with an MTK processor, then, as I already wrote, you need to use the Mobileuncle MTK Tools or ToolHero application, basically as I said above. However, here I read again: in order for these normal applications to work, you need root rights. It turns out that applications need root rights, but to call the engineering menu using special team, then root rights are not needed. If I understood everything correctly, then the situation is like this. But I found a picture, well, it shows how to enter the code (but each manufacturer has its own code, don’t forget):

By the way, I found a picture, this is the Mobileuncle MTK Tools application, look:

Well, here’s what ToolHere looks like, look:

Well, here is the EngineerMode menu itself:

Look guys, I dug up this picture, look carefully:

Here we see that the Hardware Testing tab is active, this is a type of hardware test, and here what do we see? We see audio settings, camera settings, there is even a stress test for the processor (CPU Stress Test), screen settings, in short, much that is in the engineering menu.. Once again I was convinced that in order to touch something, you need to fumble around in it. Guys, don't play with this menu out of nothing to do, it's not a toy.

Well guys, do you understand what Engineer Mode is? As you can see, it turned out that this is not a program, it’s an engineering menu, you can also say that it’s a service or service menu. But have you thought why it is needed at all? But I asked. In short, this menu is a type of secret settings that are used by specialists at the factory to optimally configure the phone so that everything works normally. Therefore you must understand that incorrect settings may make the phone inoperable.

That's all, gentlemen. Good luck and positive thinking!

Advanced users of modern smartphones and tablets take advantage of the numerous features that come with engineering Android menu. It allows you to get information about the mac address, check or configure Wi-Fi work, Bluetooth, update software cameras, speakers. Very often, using such a menu you can improve the sound on your device and make other fine adjustments. For example, return the original settings Google account, specify settings for blocking and turning off the device, set settings that allow you to create a backup copy important information. Before entering the engineering menu, you need to understand that rash actions can lead to a malfunction of the device. It is advisable for the user to remember what changes were made to the system in order, if necessary, to return all settings to their previous state.

How to enter the engineering menu using the standard capabilities of the device?

List functionality can be opened by typing a certain combination of characters in the device's call window. The Android engineering menu code varies depending on the brand of phone or tablet. Each manufacturer sets its own combination. Such information is usually indicated in the instructions for the phone and on official websites. For users modern devices Usually there are no difficulties in finding the required code.

Below we provide a table of the most common combinations. It is not recommended to use them unless your device is one of the listed brands.

The developers do not recommend performing similar commands without specific knowledge and experience. But often only this method helps to quickly solve a number of problems related to, returning the device to its original state, and obtaining additional information about the device. The engineering menu is presented at English language, making it understandable for most users.

Using additional programs

It is not always possible to find out the combination that is suitable directly for your device. In such situations, you can install special software on your mobile device, which will allow you to open a list of the functionality of your smartphone or tablet with a few clicks. It is publicly available to different versions Android and device models.

The program for entering the Android engineering menu can be installed via a USB connection to personal computer or laptop. One of them is called Mediatek Engineer Mode. It is a file EnMode.apk, which must be transferred to the device memory and installed in the usual way. This program is suitable for devices operating on the MTK processor. The user has the opportunity to download free and paid versions of the software.

In the shop Google Play It is possible to download the Mobileuncle MTK Tools utility. It is designed for smartphones and tablets running Android 2.1. and later versions. The description says that such a utility is also only suitable for devices equipped with an MTK processor.

The Mobileuncle Tools program is suitable for owners. There are other utilities, for example, Shortcut Master, MTK engineering menu, launching MTK engineering menu. Before installing them, we recommend that you read the application rating, reviews from other users, and also check your device for compatibility.

Setting up optimal sound by opening the engineering menu

One of the most common reasons why users look for information on how to enter the engineering menu is the need fine tuning sound. The following situations may occur:

Poor audibility when the speakerphone is on
Sudden changes in sound when incoming call while listening to audio
Insufficient signal volume
Quiet sounds while recording video
Quiet operation of the headset and microphone.

This is just a small list of installed settings that can be changed through the engineering menu of a modern mobile device. Sound settings are done through the Audio section, which is displayed immediately after entering the menu. Then various tabs will appear on the screen, such as Headset Mode. This tab allows you to set sound parameters that are activated when you connect a headset. Normal Mode sets the sound to normal condition mobile device (without connecting headphones or speakers).

LoudSpeaker Mode tab, which are activated when the loudspeaker is turned on. Headset LoudSpeaker Mode allows you to make settings for active mode speaker while a headset is connected to it. The Speech Enhancement tab provides settings that come into play when communicating over a mobile network.

In any of the modes, you can fine-tune the microphone or increase the volume (see table).

The volume of any sound parameter has seven levels - from 0 to 6. The higher the value, the louder your device will sound. We do not recommend installing maximum settings, because it promotes fast . In many devices, setting the volume to maximum can result in unpleasant noise.

The engineering menu is a mechanism for fine-tuning mobile devices operating on Android platform. For developers, the list of such features opens up new options when implementing applications. Of course, such a menu is used not only for adjusting sound parameters. It is an essential tool for keeping smartphones and tablets running optimally. But it's best not to make changes you're not sure about.

Having become the owner of a Meizu phone, the user may find that his device does not always work correctly. The sound turns out to be too quiet, the connection is not always stable, and other dysfunctions are observed that need to be corrected. To solve these and similar problems there is a special engineering menu (engineering mode), which allows you to fine-tune your phone, as well as track its key characteristics along the way. After I talk about entering the engineering menu on Meizu phones, you will have an order of magnitude more options. But it is worth mentioning that, or it is possible without entering the specified menu.

Necessary information about the engineering menu in the phone

As you know, a full engineering menu is available only for Meizu gadgets running on MediaTek processors. On alternative Qualcomm processors, this menu is either absent or available in a rather stripped-down form, with very poor functionality.

By default, the engineering menu is hidden from the user's view. This is explained by the desire of the developers to protect important phone settings from interference by the incompetent owner of the gadget. If you need, use my recommendations at the link.

After all, the main purpose of the engineering menu is to debug the phone at the final stage of testing, check the functionality of system components, and take readings of individual sensors by the developer and the direct manufacturer. Making unqualified changes to the phone through the engineering menu may result in exit Meizu devices out of order, with the possibility of turning it into a lifeless brick.

Therefore, if you decide to make any changes through the engineering menu, then make sure that you know what you are doing and that the changes you make will not cause your phone to malfunction.

How to open the engineering menu on Meizu devices

To go to the engineering menu on Meiza, you can use several methods:

Use special code, which is dialed in the dialing application. Go to the appropriate application on your phone, and type there:

*#*#3646633#*#*

If nothing happens after typing this combination, try alternative combinations:

*#*#4636#*#* or *#15963#*

If for some reason these codes did not work, then to gain access to the engineering menu I recommend using special mobile applications level “MTK Engineering Menu”, “MTK Engineering Mode” and other analogues. You will need to download them through the application store, launch them, and then use them to access the engineering menu of your gadget.

After entering the appropriate code, the corresponding interface (engineering mode) will open in front of you. Let's take a closer look at its features.

Additional menu options from Meizu

Despite the fact that the features of the engineering menu may differ depending on specific model Meizu phone, usually such a menu has six main tabs, each of which contains a number of relevant parameters. Let's take a closer look at these tabs:

By working with the capabilities of a particular tab, you can more finely customize your gadget to suit your requirements. At the same time, your intervention must be of a qualified nature, so I would not recommend simply changing the parameters as you please.

Conclusion

In most cases, to switch to the engineer mode, you need to dial the specified combination *#*#3646633#*#*, and you will immediately be taken to the “engineering mode” on your gadget.

Users of mobile devices often confuse the Android engineering menu with the developer menu, although the vast majority of users know nothing and are not even aware of its existence.

But those who don’t chase new products and don’t buy smartphones/tablets every time they appear new version Android also dream of expanding the capabilities of their device.

To solve the problem, you can go in several ways:

obtain superuser privileges (root rights);
install several applications that add new features and provide access to features hidden from the user’s eyes;
use the developer menu (mainly for comprehensive verification and testing of the device);
go to the internal system menu (engineering)

We’ll talk about the purpose and capabilities of the latter, having previously found out how you can get to it. various gadgets, firmware and editions of the mobile OS.

How to log in

The most common calling option on an Android device is to enter a combination "*#*#3646633#*#*".

Attention! There are a couple of nuances here:

firstly, after entering the combination, you do not need to press the call button; a couple of seconds after entering the last asterisk character, the required interface will appear on the smartphone screen;
The method is applicable to most, but not all devices and firmware versions, especially to Chinese devices;
The appearance and functions provided may differ on different devices (number of categories, names, differences in versions, etc.).

On other models you should try entering *#*#4636#*#* or *#15963#* . Combinations for mobile devices The most popular manufacturers are shown in the table below.

Table 1 – Codes for calling Engineer Mode on devices of different developers

Samsung	*[##4636##]* *[##8255##]*
LG	*[#546368#818#]*
Sony	*[##7378423##]*
Huawei	*[##2846579##]* *[##2846579159##]*
Acer	*[##2237332846633##]*
HTC	*[##3424##]* *[##4636##]* *[##8255##]*
Fly Philips Alcatel	*[##3646633##]*

If you can't call

It is very rare, but it may be that none of the above combinations resulted in the required window being called. In this case, download the Mobileuncle MTK Tools application (removed from the Play Market).

It works similarly to the methods described above, with the difference that the commands for entering codes are sent to the mobile operating system automatically, determining its version and gadget model after calling the “Engineer Mode” command.

Before using the program, it is strongly recommended to create a backup of the firmware; it is not for nothing that it has been removed from the application store - many dozens of users have “killed” the firmware of their devices due to inept and careless handling of the software. In addition to calling options, the program allows you to:

free up permanent and RAM memory;
restart recovery;
manage autostart;
backup, restore and edit IMEI;
display detailed information about the smartphone hardware.

To gain access to all the features of Mobileuncle MTK Tools, as well as the capabilities of the options, you should acquire root rights for your mobile device.

Composition of the extended interface

Engineer Mode for the user is presented in the form of a multi-tab window, where each tab contains certain types of functions.

Telephony

The first tab contains functions to perform general settings phone:, testing the network and obtaining information about the network technologies used, changing GPRS parameters, configuring the camera and a lot of sub-items that are incomprehensible to a beginner.

Connectivity

Responsible for changing parameters and displaying information about ports for communication:

Bluetooth;
Wi-Fi module;
FM receiver if available.

You can request comprehensive information about each module, test its operation, change the configuration and look through the logs.

Hardware Testing

The title of the section indicates that there are tools for working with hardware: testing it, extracting any information about hardware components, changing their operating modes.

On Android it supports more than a dozen audio playback modes for various conditions (games, calls, alarms).

As for the camera, a huge range of parameters is available here, which includes changing preview videos and specifying the default video frame rate and many other items.

To test stability and performance central processor Through it you can run a processor stress test.

Changing its voltage and operating frequency in order to overclock or save the battery should be done with extreme caution and being aware of the possible risks.

The processor has the option of putting it into sleep mode under certain conditions, as well as turning off the display.

Engineer Mode also contains a huge number of items for retrieving information and debugging the processor, touch display, random access memory, sensors.

There are functions to stop removable flash memory and change the operating mode of the USB port.

Location

For those who like to use GPS capabilities, who sometimes lack its settings, there is an abundance of items available in this tab.

Resetting to original settings

It has never happened to anyone that the thirst for experimentation led to small disasters.

If something goes wrong during use, everything can be returned, especially if backup copy firmware has been done.

Even if you haven’t acquired it, you shouldn’t lose heart, we’ll reset the device to factory settings and that’s it.

The first and most reliable way is to roll back the system state to reserved.
Resetting the firmware via recovery (BackUp and Wipe).
Download Mobile Uncle, call “Restart in Recovery mode" and click on the item "BackUp"

The engineering menu is truly an indispensable tool for fine-tuning a smartphone/tablet, allowing you not only to take full control of your gadget, but also, sometimes, to return one of the non-working functions. However, its careless use can lead to problems.
