How to enter the engineering menu honor 4x. How to open and configure the engineering menu on Android - instructions and secret codes

Mobile equipment of Huawei and its separate brand Honor, running operating system Android has firmly established itself in today's market. In addition to extensive device customization in its own EMUI shell, developers also provide access to in-depth changes in system settings in the engineering menu. After reading the article, you will learn how to access it.

Go to the Huawei service menu

Engineering menu is a settings panel in English, in which you will be able to change various gadget parameters and complete information about it. These settings are used by developers during the final check of the device, just before it is released for sale. If you are not sure of your actions, then do not change anything in the menu, as this may lead to unstable operation of the 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. Therefore, think carefully whether it is worth it not enough loud speaker or experiments with the camera.

Nowadays, phones are in no way inferior to computers in complexity. Accordingly, there are many options “hidden” from the average user, who, using them ineptly, can turn his gadget into a brick. One of these options is the engineering menu.

What is the engineering menu

The service menu allows you to manually configure absolutely any phone parameter. It is also used by manufacturers before sending the gadget for sale in order to rebuild and debug the operating system for the most comfortable operation of the device for the user. Some companies even remove the ability to enter the engineering settings, but, fortunately, in Honor phones this option remains and is fully available.

Ways to enter the engineering menu

Method 1: through the application. Surely, you have already heard about this possibility before. I strongly advise against going this route. Firstly, because, as you can see in the screenshot below, the lion's share of the options offered by PlayMarket work on MTK processors, and the Honor line and model 6a in particular are equipped with Qualcomm.

Secondly, it is not a fact that the rest are optimized specifically for our country and for our device. In order to see a clear example of an unsuccessful choice, you can go to the reviews about "Hidden android settings". This is the fourth option in the issue. This application is designed for users in the United States, and their mobile operators operate on frequencies different from ours. As a result, for many users of this application, the SIM card frequency settings have been lost, and all they can now do is take the phone to a service center.

Method 2: through the introduction of the code. This is a more reliable way. The engineering menu, of course, is still a risky undertaking, but here you are less likely to turn the phone into a “brick” than when entering this menu through applications.

Although many now consider Honor to be a company that produces gadgets, it is still the brainchild of Huawei, and it is the Huawei code that is suitable for entering the phone’s service menu: *#*#2846579#*#*. Do not try to enter the standard Android code, it will not work. So, in order to open the menu, do the following:

1. Open the numeric keypad, in which you usually enter a phone number;
2. Manually enter the code mentioned above. Don't try to copy and paste it. The main condition is manual entry. You don't even need to press the call button, as soon as you enter the last character, you will see the following:

This is our menu. It is always in English, so if you are not strong in languages, you will have to be patient and open Google translator.

Engineering menu features

Let's go through the main points of the mode to make it easier for you to understand.

1. backgroundsettings. There are only two items here: USB port settings and Logs. If the first does not need to be explained, then the second paragraph is used to debug the gadget. For example, there are items "Charging logs" and "Sleep logs";

2. Board info. We will translate this crookedly as “Information on board”, so that through associations it will be better remembered. This section contains all possible information about the phone and accessories. For example, if you want to know the IMEI of the device, at this point you will need to click on "Others".

3. The Network section contains all the data on the operation of networks. This is not only the Internet, but also telephony;

4. In "SoftwareUpgrade" you can upgrade from a USB flash drive.

Android smartphone manufacturers implement and use the engineering menu to test devices. 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 enter the engineering menu.

Why do you need a hidden engineering menu in Android

The Engineering Menu (Engineering Mode) is an inherently hidden application that developers use to test and set the optimal parameters for a mobile phone or tablet. Specialists check the operation of sensors and, if necessary, make adjustments to the functioning of system components.

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

How to enter the menu

To open the menu set 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 you cannot start the service menu in the standard way, use third-party applications - you can download them on PlayMarket. Recommended programs - "Start the MTK engineering menu", Mobileuncle Tools, Shortcut Master.

Manufacturers menu does not work on some device models with Android 4.2 JellyBean (x.x.1, x.x.2) and Android 5.1 Lollipop. Also the menu is invalid when installed firmware Cyanogen mod. In Android 4.4.2, the changes made in the application are reset on reboot.

"Launching the MTK engineering menu"

The application allows you to open and configure the engineering menu without a set of digital commands. Works correctly on MediaTek processors (MT6577, MT6589, etc.) and Android 2.x, 3.x, 4.x, 5.x systems. 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

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

Shortcut Master Utility

The Shortcut Master program is designed to work with shortcuts and system applications: creating, searching, deleting. There is no direct function to enter the engineering menu. But with its help, you can view a list of secret commands that are active 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 doesn't require any extra work.

Root rights to access the engineering menu

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

Possible problems and solutions:

What can be configured in the menu

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

Audio: increase volume level

If your phone is not loud 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. Vol - maximum 200. Press the SET button to save the settings.

Audio: increase the volume of a telephone conversation

To boost the tone of the speaker for conversations, in the Audio section of the service menu, select Normal mode and open the Sph. Set the values ​​for the 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 see if the other person hears you better.

Battery: disable unused frequencies

Smartphones quickly use up battery life for running applications, maintaining cellular communications 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, a pair of 900/1800 MHz operates, which means that 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 the Band Mode item. Disable unused frequencies by unchecking the corresponding items - PCS1900 and GSM850. If the device supports two SIM cards, open SIM1 and SIM2 in turn and follow the steps in each. Press the SET button to save the settings.

If your smartphone and SIM card work in 3G networks, disable 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 tend to shoot and process their footage in RAW for 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 video. After changing each parameter, remember to press SET to save the settings.

recovery mode

Recovery Mode (Recovery Mode) - an analogue of Bios on a computer, allows you to manage the device without logging into the Android system. Recovery Mode Features:

In Recovery Mode, do not perform an action if you are not sure what it will lead to. Some commands can harm the device and the 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 the device is rebooted, try entering the technical menu not through the application, but using a digital command.

Service codes for Android devices

In addition to the 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.

Table: list of secret commands for Android

If for some reason the service code did not work, do not be discouraged - install and run the Secret Codes application (Google Play link: https://play.google.com/store/apps/details?id=fr.simon.marquis. secretcodes&hl=en). The program will analyze the combinations valid in the device and offer you a list. You can activate the combination directly in the application with one click on the name.

There are many ways to improve mobile device on Android using the engineering menu. The menu structure differs in different device models, but the basic functionality is preserved everywhere. When opening and changing parameters in the service section, be careful - some commands lead to system failures and device failure.

Many of us have long been fond of smartphones based on the Android operating system. They have always bribed with their unpretentiousness, good reliability, as well as convenience and ease of use. The same can be said, in particular, about the smartphones of the well-known company Huawei, 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 in the android smartphone market.

However, few of us know that the already quite comfortable Huawei phones can be made even better with the help of fine-tuning “for themselves”. What we can configure in the main menu of the phone is just the tip of a huge iceberg, the rest is hidden from users in order to prevent the device from failing. However, people who deal with mobile devices not just at the user level, but, for example, work in a service, easily get access to 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 corny ruin their device by inattention. 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 for the finest settings of your device.

The engineering menu provides the user with access to manual configuration of almost all phone parameters. Typically, engineer mode is used by developers at the stage of the final configuration of the device before it goes on sale. With it, they check the device for various errors, malfunctions, and also check the performance 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 sewn directly into the Android program, however, on some phone models, the developers intentionally remove it from the phone after the final check. In such cases, it will be difficult for the owner to set up the device “for themselves” directly from the phone and he will either have to use special programs that can be downloaded, for example, on Google Play, or use third-party firmware.

The engineering menu for Huawei smartphones is usually always in place and never deleted, so if you didn’t manage to get into these settings the first time, then most likely you simply didn’t take into account the unique features of your device. It is also worth reiterating that if you are not sure 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 you change the system settings, you lose the warranty and bear full responsibility for the device yourself.

How to get into 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, the codes can very often change depending on the specific model of the device and the type of single-chip system used in it. Also, it often depends on the single-chip system of the phone whether the smartphone has a built-in engineering menu at all or not. So, on devices with MTK processors, there is such a menu on almost every device, and on devices equipped with Qualcom processors, on the contrary, in most cases this menu is completely absent.

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

Menu commands

If you do not 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 devices manufactured by Huawei support the so-called " service codes", which partially repeat the functions of the engineering menu.

Service codes apply to 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 completely not so convenient and completely unsafe. Some of them can literally delete all the data stored on the phone or disable certain functions of the device. So, if you are not one hundred percent sure what this or that code means, we do not recommend that you use it for the simple reason that they can disrupt the normal functioning of your phone.

Now let's see 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 to factory settings such settings as: Google account data, system data and settings, downloaded applications.
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 modes of the button on / off.
7. *#*#273283*255*663282*#*# - with this command, you can open the file copy screen and use it to Reserve copy your most valuable photos or audio recordings.

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

Engineering menu functions

The Huawei engineering menu offers a wide variety of settings for advanced users. On most phone models of the Chinese company, volume controls, camera settings, navigation, telephony and many other functions are available that you can modify to your liking.

In fact, there is nothing complicated in the adjustment itself. Just look for the parameter you need, for example, the volume level, open it and experiment with the values ​​until you achieve the ideal result for you. However, we 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 annoying plastic.

Telephony

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

1. Auto Answer. Here you will be able to enable or, conversely, disable auto-reply to incoming call.

1. Band Mode. Here you can manually select frequencies for the GSM module. This menu will show all frequencies supported by your phone. You can uncheck those ranges that are not provided by your operator mobile communications, which will greatly save your battery power.
