Nowadays, phones are as complex as computers. 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 parameter of the phone. It is also used by manufacturers before sending the gadget for sale in order to build and debug the operating system for the most comfortable operation of the device for the user. Some companies even remove the option to enter engineering settings, but, fortunately, in Honor phones this option remains and is fully available.
Ways to enter the engineering menu
Method 1: through the app... You've probably heard of this possibility before. I strongly advise against going this way. First, because, as you can see in the screenshot below, the lion's share of the options offered by PlayMarket runs 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 search result. This app is intended for users in the United States and their cellular operators operate on frequencies other than ours. As a result, many users of this application have lost their SIM card frequency settings, and all they can do now 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 have less chance of turning your phone into a "brick" than when you enter this menu through applications.
Although many people now consider Honor to be a company that produces gadgets, it is still the brainchild of Huawei, and the Huawei code is suitable to enter 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:
- We open the numeric keypad, into which you usually enter the phone number;
- 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 be presented with 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 figure it out.
- Backgroundsettings. There are only two items here: USB port settings and Logs. If the first is not required to be explained, then the second point is used to debug the gadget. For example, there are items "Charging Logs" and "Hibernation Logs";
2. Board Info. We will crookedly translate this as "Information on board" so that it will be better remembered through associations. This section contains all possible information about the phone and accessories. For example, if you want to find out the IMEI of the device, at this point you will need to click on "Others".
3. The Network section contains all the data on network operation. 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 for testing 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 an application from PlayMarket, anyone can enter the engineering menu.
Why do you need a hidden engineering menu in Android
The Engineering Mode is essentially a hidden application that developers use to test and set optimal parameters for a mobile phone or tablet. Experts check the operation of the sensors and, if necessary, make adjustments to the functioning of the system components.
When working with the Android technical menu, be careful - changing some functions leads to device malfunctions.
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.

Video: how to work in Engineer Mode
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 engineering menu MTK", Mobileuncle Tools, Shortcut Master.
The manufacturers menu does not work on some device models with Android 4.2 JellyBean (x.x.1, x.x.2) as well as Android 5.1 Lollipop. Also the menu is invalid when the Cyanogen Mod firmware is installed. In Android 4.4.2, when you reboot, the changes made in the application are reset.
"Launching the engineering menu of MTK"
The application allows you to open and configure the engineering menu without typing digital commands. Works correctly on MediaTek processors (МТ6577, МТ6589, etc.) and Android 2.x, 3.x, 4.x, 5.x systems. According to user reviews, the program successfully performs its functions, but after restarting 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 can view information about the screen, sensor and device memory, as well as update the firmware, restore the IMEI number and improve GPS. Root rights are required for stable operation.
Shortcut Master Utility
Shortcut Master is designed to work with shortcuts and system applications: create, search, delete. There is no direct function for entering the engineering menu. But with its help you can view a 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 into the service menu on some versions of Android, the user must have superuser (root) rights. You can get the rights using specialized applications: Farmaroot, UniversalAndRoot, Romaster SU and others. To get Root access to a device using Farmaroot:

What can be configured in the menu
The appearance of the engineering mode and the options for adjusting the parameters may differ depending on the tablet or smartphone model. In the menu, users most often adjust sound, change camera settings, and use recovery mode. The parameters for adjustment and the procedure for action are shown below. Be careful - the names of the menu items may differ in different device models! You act at your own risk.
Audio: boost volume
If your phone is not ringing 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 \u200b\u200b- 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 enhance the tone of the speaker for conversations, in the Audio section of the service menu, select Normal mode and open the Sph item. Set the values \u200b\u200bfor 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 check if the other person can hear you better.

Battery: cut off unused frequencies
Smartphones quickly drain battery power for applications, cellular 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. A pair of 900/1800 MHz operates in Russia, 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 items SIM1 and SIM2 one by one and follow these steps in each. Press the SET button to save the settings.
If your smartphone and SIM card work in 3G networks, disconnect 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. In the meantime, photographers prefer to shoot and process their footage in RAW for more editing options. The technical menu allows you to select the desired picture 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 images, set the ISO value, enable shooting in HDR for higher details of the photo, set the frame rate for video. After changing each parameter, remember to press SET to save the settings.
Recovery mode
Recovery Mode - analogous to Bios on a computer, allows you to control the device without logging into Android. Recovery Mode Features:
In Recovery Mode, do not perform an action unless you are sure of what it will lead to. Some commands can damage 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 the SET button at the bottom of the screen. If the parameters are reset after restarting the device, try to enter the technical menu not through the application, but using a digital command.
Service codes for devices on Android
In addition to the technical menu, secret USSD codes allow you to control the functionality of smartphones on Android - combinations of numbers and symbols, by typing which the user performs an action. Secret codes for different devices are shown in the table.
Table: list of secret commands for Android
If for some reason the service code didn't work, don't be discouraged - install and run the Secret Codes app (Google Play link: https://play.google.com/store/apps/details?id\u003dfr.simon.marquis. secretcodes & hl \u003d ru). The program will analyze the combinations operating 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 your 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 breakdown.

In the menu of the Huawei smartphone, you can change a lot of settings, however, many users do not even realize that the device contains hidden additional settings available in a special engineering menu. Smartphones running Android OS can switch to the corresponding interface in two ways.
The first and most common method is to enter generic code. To enter the engineering menu of Huawei Honor, Huawei Nova or Mate in this way, you need:
- Open a standard application for making calls (in other words, "dialer").
- Enter the code in the same way as for a regular phone number. For Huawei devices, combinations are suitable *#*#2846579#*#* or *#*#2846579159#*#* .
- Press the call button and wait for the menu to appear.
The functionality of the additional interface offered by the system is quite wide, but it will not work to change the screen brightness or increase the volume in the engineering menu of this type. This will require a second method - entering a specialized code
*#*#14789632#*#*
After activating it, a menu will appear in which you can change system parameters. The greatest scope for modifying a smartphone is provided by the Hardware Testing tab, where you can test and change the settings for sound, video, display and other parameters.
It will not be easy for people with poor knowledge of the English language to understand the engineering menu, so it is better to thoroughly study all the parameters and their names before changing one or another function. Better yet, do not change anything there yourself, so as not to break the phone.
Mobile technology from Huawei and its separate brand Honor, running the Android operating system, has firmly established itself in the modern market. In addition to the extensive configuration of the device in its own EMUI shell, the developers also provide access to in-depth change of system parameters in the engineering menu. After reading the article, you will learn how to access it.
We go to the service menu Huawei
The engineering menu is a settings panel in English, in which you will be able to change various parameters of the gadget and complete information about it. These settings are used by developers during the final check of the device, just before its release for sale. If you are not sure of your actions, then do not change anything in the menu, as this can lead to unstable operation of your smartphone or tablet.
In conclusion, I would like to add that in the case of inept or incorrect manipulations in this menu, you can only harm your gadget. So think carefully about whether the speaker is not loud enough or experimenting with the camera is worth it.
