How to open and configure the engineering menu on Android - instructions and secret codes. Engineering menu for Huawei Honor 6 smartphones engineering menu

Manufacturers of Android smartphones implement and use engineering menu. It contains all kinds of tests and device settings that are not available to ordinary users. However, today, knowing the USSD command or downloading the application from PlayMarket, anyone can go to the engineering menu.

Why do you need a hidden engineering menu in Android?

Engineering menu (Engineering Mode) – at its core hidden application, which developers use to test and set the optimal parameters for a mobile phone or tablet. Specialists check the operation of the sensors and, if necessary, make adjustments to the functioning of system components.

Working with technical Android menu, be careful - changing some functions leads to malfunctions of the device.

How to enter the menu

To open the menu installed by the manufacturer, activate the dial pad on your smartphone and enter one of the USSD commands presented in the table. After entering the command, the numbers will disappear from the screen, and a menu will open instead.

If the code does not work and in a standard way it is not possible to start the service menu, use third party applications- You can download them on PlayMarket. Recommended programs - “Launch the MTK engineering menu”, Mobileuncle Tools, Shortcut Master.

The manufacturer menu does not work on some device models with Android 4.2 JellyBean (x.x.1, x.x.2), as well as on Android 5.1 Lollipop. The menu is also invalid when installed firmware Cyanogen Mod. In Android 4.4.2, when you reboot, changes made in the application are reset.

“Launch the MTK engineering menu”

The application allows you to open and configure the engineering menu without typing digital commands. Works correctly on MediaTek processors (MT6577, MT6589, etc.) and Android systems 2.x, 3.x, 4.x, 5.x. According to user reviews, the program successfully performs its functions, but after rebooting the smartphone, the settings made using the application are reset.

Mobileuncle Tools program

The functionality of the application is similar to the previous one, but, in addition to accessing the engineering menu, the user has the opportunity to view information about the screen, sensor and device memory, as well as update the firmware, restore the IMEI number and improve GPS. For stable operation, root rights are required.

Shortcut Master utility

The Shortcut Master program is designed to work with shortcuts and system applications: creation, search, deletion. It does not have a direct function for entering the engineering menu. But with its help you can view the list of secret commands operating on your device. And by clicking on the name of the command, you will see a drop-down menu in which there will be an item “execute”. Convenient and does not require unnecessary actions.

Root rights to access the engineering menu

To get to the service menu on some versions of Android, the user must have superuser rights (root). You can obtain rights using specialized applications: Farmaroot, UniversalAndRoot, Romaster SU and others. To get Root access to your device using Farmaroot:

1. Install and run the program. Link in Google Play: //play.google.com/store/apps/details?id=com.farmaapps.filemanager&hl=ru.
2. If the application supports installing root rights on your device, then on the screen you will see a list of possible actions, among them - “Get root”. Select this item.
3. Choose one of the preset root methods.
4. The program will begin installation.
5. At the end of the procedure, you will see a success message. root installation access.

Possible problems and solutions:

• the application closed mid-installation - restart the device and try again;
• root rights are not installed - try installing using a different method (select a new exploit in the application).

What can be configured in the menu

The appearance of the engineering mode and the ability to adjust parameters may vary depending on the tablet or smartphone model. In the menu, users most often adjust the sound, change camera settings and use recovery mode. The parameters for adjustment and the procedure are given below. Be careful - the names of menu items may differ in different device models! You act at your own risk.

Audio: Increase volume level

If your phone does not ring loudly enough, find the Audio section in the engineering menu and go to LoudSpeaker Mode. Select Ring. For each signal level (level 1–6), change the values ​​- set the numbers in ascending order, from 120 to 200. Increase the value in the Max item. Vol - maximum 200. Press the SET button to save the settings.

Audio: Increase phone call volume

To enhance the speaker tone for conversations, in the Audio service menu section, select Normal mode and open the Sph item. Set the values ​​for signal levels (level 1–6) from 100 to 150, and the number for Max. Vol. – up to 160.

To increase the sensitivity of the microphone, go to the menu Audio - Normal mode - Mic. For each level, assign the same microphone sensitivity values, for example, 200. Press the SET button, reboot and check whether the other party can hear you better.

Battery: Disable unused frequencies

Smartphones quickly consume battery life running applications, maintaining cellular communication And network connections. Using the engineering menu you can increase the battery life.

Modern devices scan several GSM frequencies - 900/1800 MHz and 850/1900 MHz. In Russia there is a 900/1800 MHz pair, which means there is no need to scan the network at other frequencies. The radio signal for the second pair can be turned off, which will significantly save the charge level.

In Engineer Mode, open Band Mode. Disable unused frequencies by unchecking the corresponding items - PCS1900 and GSM850. If the device supports two SIM cards, open the SIM1 and SIM2 items one by one and perform the indicated steps in each. Press the SET button to save the settings.

If your smartphone and SIM card operate in 3G networks, disable the networks that are not used in Russia: WCDMA-PCS 1900, WCDMA-800, WCDMA-CLR-850. Press the SET button again.

You can enable scanning of disabled networks by returning to the same menu and checking the boxes.

Camera: photo and video settings

By default, Android devices save pictures in JPEG format. Meanwhile, photographers prefer to shoot and process material in RAW to gain more editing options. The technical menu allows you to select the desired image format.

Find Camera in the menu and select Capture Type. Set the photo format to RAW and press SET. Also in the Camera menu you can increase the size of pictures, set the ISO value, enable shooting in HDR for higher photo detail, and set the frame rate for videos. After changing each parameter, remember to press SET to save the settings.

Recovery Mode

Recovery Mode(Recovery mode) - analogous to Bios on a computer, allows you to control the device without logging into the Android system. Recovery mode features:

• resetting settings to standard;
• firmware update;
• access to root rights;
• Creation backup copy OS;
• removal of personal data from the system.

In Recovery Mode, do not perform an action if you are not sure what it will lead to. Some commands may harm the device and system.

If the settings are not saved

Users who have access to the technical menu complain that the parameters changed in it are not activated or are reset when the device is restarted.

To activate the settings after changing the parameters, tap on the SET button at the bottom of the screen. If the parameters are reset after rebooting the device, try accessing the technical menu not through the application, but using a digital command.

Service codes for Android devices

Besides technical menu, secret USSD codes allow you to control the functionality of Android smartphones - combinations of numbers and symbols, by typing which the user performs an action. Secret codes for different devices are given in the table.

If for some reason the service code did not work, do not worry - install and run the Secret Codes application (Google Play link: //play.google.com/store/apps/details?id=fr.simon.marquis.secretcodes&hl= ru).

The program will analyze the combinations active in the device and offer you a list. You can activate the combination directly in the application with one click on the name. Mobile equipment of Huawei and its separate brand Honor, operating under the control of the operating system Android systems

, has firmly established itself in the modern market. In addition to extensive device configuration in its own EMUI shell, developers also provide access to in-depth changes to system parameters in the engineering menu. After reading this article, you will learn how to access it.

Go to the Huawei service menu The engineering menu is a settings panel on English language , in which you will be able to change various parameters of the gadget and full information about him. These settings are used by developers during the final testing of the device, immediately before its release for sale. If you are not sure of your actions, then do not change anything in the menu, as this may lead to unstable work

smartphone or tablet.

In conclusion, I would like to add that in case of inept or incorrect manipulations in this menu, you can only harm your gadget. So think carefully about whether a speaker that isn't loud enough or experimenting with your camera is worth it. Many of us have fallen in love with smartphones based on Android. They have always captivated us with their unpretentiousness, good reliability, as well as convenience and ease of use. The same can be said, in particular, about the well-known smartphones, which are also based on this operating system. A company from the Middle Kingdom always keeps up with the times and equips its phones with the most latest versions operating system and multifunctional firmware, trying to keep up with the generally recognized leaders of the Android smartphone market.

However, few of us know that there is already enough convenient phones Huawei can be made even better by fine-tuning it to your liking. What we can configure in the phone’s main menu is only the tip of a huge iceberg; the rest is hidden from users in order to avoid device failure. However, people who deal with mobile phones not just at the user level, but, for example, work in a service, can easily access advanced settings on almost any phone using the engineering menu.

Looking ahead a little, it’s worth saying that inexperienced users really shouldn’t go into this “forbidden forest”, so as not to simply ruin their device through carelessness. But if you are confident in yourself and think that you understand technology at a sufficient level, then the Huawei engineering menu is exactly what you need to fine-tune your device as much as possible.

The engineering menu provides the user with access to manual setting almost all phone parameters. Typically, engineer mode is used by developers at the stage of final configuration of the device before it goes on sale. With its help, they check the device for various errors, malfunctions, and also check the functionality of all device systems. In addition, the engineering menu contains detailed information about the capabilities of the device and its programs.

The engineering menu is built directly into the Android program, however, on some phone models, developers deliberately remove it from the phone after final testing. In such cases, it will be problematic for the owner to customize the device “for himself” directly from the phone and he will have to either use special programs, which can be downloaded, for example, from Google Play, or you can use firmware from third-party developers.

The engineering menu for Huawei smartphones is usually always in place and is never deleted, so if you were unable to get into these settings the first time, then most likely you simply did not take into account the unique features of your device. It is also worth repeating once again that if you are not sure of what you are doing, and working with such menus is new to you, then you should carefully consider this step. Remember that unsuccessful settings in the engineering menu may not improve the functioning of the smartphone, but, on the contrary, make it much more inconvenient, and if changed system settings You lose the warranty and bear full responsibility for the device yourself.

How to get to the engineering menu?

In order to get into the engineering menu of a phone based on the Android operating system, you need to enter a certain secret code in the phone dialing menu. Most often on Android devices you need to dial the combination *#*#3646633#*#*. This code is suitable for most Android smartphones, but sometimes developers can change it, for example, entering the Huawei engineering menu most often occurs using the codes *#*#2846579#*#* or *#*#2846579159#*#*.

Also, codes can very often change depending on specific model device and the type of single-chip system used in it. Also, it often depends on the phone’s single-chip system whether the smartphone even has a built-in engineering menu or not. So, on devices with MTK processors, such a menu is available on almost every device, but on devices equipped with Kvalcom processors, on the contrary, in most cases this menu is completely absent.

The code should be applied immediately as soon as you enter it on the call screen, but on some phones you sometimes also need to press the call button for the code to work properly. It is also worth noting that the code must be entered and not copied, since otherwise it will not work. It is also quite useless to save such codes in phone book, that is, manual input is a prerequisite for the code to be triggered.

Commands for accessing menus

If you don’t know how to enter the Huawei engineering menu — smartphone, or you can’t do it, then this is not a reason to be upset. Most Huawei devices support so-called “service codes”, which partially duplicate the functions of the engineering menu.

Service codes are used in mobile phones for a very long time and many of them appeared long before the first Android smartphones came out. However, although such codes repeat some of the functions of the engineering menu, using them is not at all as convenient and completely unsafe. Some of them can literally delete all data stored on the phone or disable certain functions of the device. So, if you are not one hundred percent sure what a particular code means, we do not recommend that you use it for the simple reason that they may interfere with the normal functioning of your phone.

Now let's look at some examples of the most useful, in our opinion, engineering codes:

1. *#06# — using this code you can find out your IMEI address.
2. *#*#4636#*#* - this code provides you with some information about the phone, namely: device data, battery information, statistics battery and phone usage statistics.
3. *#*#7780#*#* - this code resets settings such as Google account data, system data and settings, downloaded applications to the factory state.
4. *2767*3855# — this code Performs a complete formatting of the smartphone. So think twice before using it.
5. *#*#34971539#*#* — this code is intended to obtain information about the smartphone’s camera.
6. *#*#7594#*#* — used to change the on/off button modes.
7. *#*#273283*255*663282*#*# - using this command you can open the file copying screen and use it to Reserve copy your most valuable photographs or audio recordings.

There are also many other service codes that allow you to very carefully check and configure your telephone set. However, due to the fairly large number of them, this will perhaps be a topic for a separate article, and we will move on.

Engineering menu functions

The Huawei engineering menu offers a wide variety of settings for experienced users. On most models of phones from the company from the Middle Kingdom, volume adjustments, camera settings, navigation, telephony and many other functions are available that you can change at your discretion.

In fact, there is nothing complicated in the adjustment itself. Just look for the parameter you need, for example, volume level, open it and experiment with the values ​​until you achieve the ideal result for you. However, let us remind you once again that you should only change those parameters that you are sure of, otherwise you risk getting not a perfectly fitted smartphone, but a piece of irritating plastic.

Telephony

One of the main points that catches your eye when you first enter the engineering menu of an Android Huawei smartphone , This is the telephony menu. In this menu you will have access to many useful settings, including such important points as:
