Huawei and Honor engineering menu: how to enter, increase volume

Many of us have long fallen in love with smartphones based on the Android operating system. 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 smartphones from the well-known company Huawei, which are also based on this operating system. The company from the Middle Kingdom always keeps up with the times and equips its phones with the latest versions of the 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 already quite convenient Huawei phones can be made even better by fine-tuning them to suit your needs. 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.

How to save settings correctly

The recommendation to create a backup in a timely manner has already been mentioned several times above. To avoid losing important system files or damaging special sectors of your smartphone's memory, you should regularly back up all data. This procedure is especially important before flashing the firmware or entering the engineering menu.

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.

What is an engineering menu?

The engineering menu gives the user access to manual configuration of 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.

• Android engineering menu - how to disable unused GSM frequencies to save battery power

The engineering menu is built directly into the Android program, however, on some phone models, developers intentionally remove it from the phone after final testing. In such cases, it will be problematic for the owner to configure the device “for himself” directly from the phone and he will have to either use special programs that can be downloaded, for example, on Google Play, or 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 you change the system settings, you lose the warranty and bear full responsibility for the device yourself.

Hardware testing (module testing)

In addition to basic manual settings, it is possible to test individual capabilities.

1. The Audio item calibrates the speaker and reconfigures the playback parameters of audio tracks.
2. Camera allows you to adjust the creation of photos and videos.
3. CPU Stress Test - monitoring of processor systems.
4. Deep Idle Setting - sleep and standby module.
5. The Charge Battery section is responsible for the battery and charge indicator sensor.
6. The Sensor sector allows you to calibrate the sensor, which helps get rid of problems and interruptions in its operation.
7. Location Engineer Mode - location determination module.

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 often change depending on the specific device model 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 the phone book, that is, manual entry is a prerequisite for the code to work.

Commands for accessing menus

If you don’t know how to enter the engineering menu of a Huawei 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 have been 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, battery statistics 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 copy screen and use it to backup your most valuable photos or audio recordings.

There are also many other service codes that allow you to very carefully check and configure your telephone. 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

Huawei's 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.

• Huawei Honor 8. High performance in a sophisticated design

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.

Instructions for use below.

What is this functionality intended for?

First of all, the engineering menu of Huawei and Honor (as well as similar functionality on other mobile phones running Android OS) is used during the final, pre-sale debugging of equipment at the manufacturing plant.

That is, the functionality of the gadget, its components, available functionality is checked, testing is carried out for errors, and so on.

• Huawei Honor 8 Pro: characteristics and strengths

Naturally, specialists from various service centers often use these same capabilities to restore the smartphone to its former functional state.

Some manufacturers of mobile equipment, before releasing their products from the factory, completely remove this very useful tool. This is done so that inexperienced owners do not damage the purchased equipment by thoughtlessly making any changes to its operation.

Therefore, before you go into the engineering menu of Huawei or Honor, you should think several times - will you cause irreparable harm to your gadget?

Changing IMEI

IMEI is a unique numeric combination for each device. You need to change IMEI in the following cases:

• if the phone was purchased abroad and does not function in a specific country;
• you need to get Internet distribution from the operator;
• if you purchased a used gadget and want to increase the level of safety of use.

You can find out the number by looking at the box in which the phone was sold.

How to block calls from unknown numbers on Huawei and Honor

If you don't have the box handy, remove the back cover, remove the battery and look at the number on the back of the phone. You can also dial the combination *#06# and the IMEI will be displayed on the displays.

1. Activate the engineering input menu.
2. Activate the “Connectivity” / “CDS Information” / “Radio Information” / “Phone” commands.

Enter the ID number in parentheses. Click "SEND AT COMMAND" to confirm the action.

How to access?

It is logical that such access cannot be obtained through the standard phone menu. Then how to log in? Special commands are used for this purpose. It is important to note that the manufacturer of a particular brand of mobile equipment can independently change the password:

• First of all, you should try the universal option: *#*#3646633#*#*;
• If there is no result, then you should enter one of the codes that is usually used by Huawei, which also produces Honor smartphones: *#*#2846579#*#* or *#*#2846579159#*#*.

There are several important nuances that you should also be aware of:

• You shouldn’t even try to copy the password or use it by writing it in the phone book. It won't work! Manual input only. The developers specifically did this so that the user is fully aware of his actions. For example, this is a guarantee that the child will not accidentally go into the engineering menu and change the settings;
• Almost always, after entering all the necessary characters, an automatic transition occurs. But some manufacturers have made the command work only after additional use of the call button.

Options available in the Honor and Huawei engineering menu

Of course, depending on the smartphone model, some of the options may or may not be present. But there is a standard set that can be found almost always:

• Telephony. Used to diagnose mobile networks with which the device operates. You can check and configure the available bands and network parameters of a specific operator;
• Connectivity. This section is intended to evaluate the functionality of so-called wireless modules. For example, you can configure functionality such as Wi-Fi Display;
• Hardware Testing. We have collected tools designed to check the status of various modules: various sensors, smartphone screen, sound speakers, and so on;
• Location. Allows you to enable or disable location tracking using A-GPS;
• Log & Debugging. The section provides access to links to special debugging utilities that are used by manufacturers;
• Others. There are also a lot of interesting things included here. For example, in this section you can change the font used in the display on the mobile phone screen.

Additionally there are other functions. For example, you can reconfigure your smartphone cameras, change some parameters of the Wi-Fi module, analyze the functionality of the battery, and so on.

How to properly configure a new Huawei and Honor smartphone after purchase

When purchasing a device in a store, the setup is most often done by consultants and salespeople. But today every second person orders goods on the Internet, and there will be no one there to help. You'll have to figure out the algorithm yourself. For those who have not previously encountered the process of setting up a new Honor smartphone, below we have compiled comprehensive step-by-step instructions with valid tips.

1. Link your smartphone to your Google account

When you start the device, it does not yet know the country of its owner. Therefore, you immediately indicate the region and preferred language - Russian. Although there are several dozen others on the list, so you can easily choose any convenient one.

If you later want to change it, there is such a function in the settings. After that, you select the Wi-fi network. The interface offers you those that the module managed to catch nearby. You can skip this step, but it's better to set it up right away so you can sign in to your Google account later. After this, if you missed the point of connecting to Wi-Fi, the system will offer to connect to the mobile Internet. The next step is to log into Google. Do everything according to the instructions:

• enter your existing Google email address in the appropriate field;
• if you don’t have an account, click “Create” below and register (this takes up to five minutes);
• after entering the address, enter your password in the entry window;
• then the system window will prompt you to give permission to access photos, videos, contacts and other components;
• click "Allow";
• This window appears several times, agree in each case;
• Next, information is automatically synchronized from your Google account to your phone.

A Google account is convenient for many users because it acts as cloud storage.

Photos, documents and other files are placed there. Memory size - 15 GB. Any registered client receives this volume for free; additional gigabytes will have to be paid extra. If you had this account on your old phone, then sync everything there. Then on the new one you will have access to important components. The account also allows you to further protect your device from theft and loss.

1. Update your system and applications

The next step is to update the system and applications. Android also offers it automatically. The need for an update arises because the smartphone could have been assembled and released in January, but by December the version was already out of date. To ensure that new owners of Honor and Huawei equipment do not experience discomfort in use, immediately accept the update to the EMUI shell and system programs. They will then be regularly updated automatically or with your consent.

1. Enable Find My Device feature

This tool allows you to additionally protect data on the media from leakage. Thanks to the Find Device function, you can find your Honor or Huawei, lock and erase the content. But there are several requirements that are mandatory:

• the gadget must be turned on;
• Google account is active on it;
• there is access to the Internet via a mobile hotspot or Wi-Fi;
• active GPS tracking;
• The “Search for device” option is active.

If the parameters are met, the owner will quickly find the device in case of theft or loss.

If you have any questions or complaints, please let us know

1. Set up a screen lock

Locking the display is another important step towards complete security. This way you will protect yourself from worries that someone took your device without asking, looked at photos, read correspondence, etc. There are several block options:

• pin;
• password;
• graphic key;
• face unlock;
• fingerprint.

Now let's look at each option in order. A pin code is the simplest and most practical thing. However, do not put simple combinations like “0000”, “1234” or your date of birth on it. This is due to the fact that attackers have the risk of quickly picking up the key and gaining access to the desktop. A password is a more secure method of protection. If the pin consists of four characters, then the password is a long numeric value. Here, too, the rule applies not to use generally accepted combinations or personal information as a key. Come up with a complex cipher that attackers cannot solve.

Another method of protection that is present on all modern tablets and phones is a pattern. This is an image that you draw with your finger on the display. If the figure matches, the system removes the block from the phone. Next, there are two methods of protection that devices of the middle and high price categories have. Mid-price gadgets can boast a fingerprint scanner, so owners of budget smartphones will have to use another option. The principle works like this:

• the owner stores information about a fingerprint (or several);
• If you want to access the desktop, you just need to touch the sensor with your finger.

And the last option available to owners is face id. This is a technology that reads the owner’s face through the front camera. The only risk is that if you have a twin or someone similar to you, the system may mistake him for you.

1. Activate Smart Lock

Smart Lock is an option that is available on almost every modern Android device. It allows you to further protect information on your phone. It happens that when one code or key is used for a long time, attackers recognize it. Smart Lock technology allows you to unlock your phone only at a certain distance from another trusted gadget. For example, a fitness tracker or smart watch. The devices connect via Bluetooth and are constantly connected. If you are holding a smartphone in your hands and wearing a watch or bracelet on your wrist, Honor/Huawei will unlock without any problems. When setting up a gadget from scratch, the system will definitely offer to install Smart Lock.

1. Set a schedule for Do Not Disturb mode

Every phone has at least three sound modes.

1. Standard. Sound alerts are included for all calls, messages, notifications, alarms, etc.
2. Soundless. The phone responds to calls and notifications only with vibration and a light indicator.
3. Do not disturb. The gadget does not produce sounds, vibrations, or light signals during incoming calls.

The third mode is very useful during sleep, for example, it is set from 22:00 to 7:00 so that you cannot be woken up by someone’s calls or SMS at a later time. It can also be installed in educational institutions so that the device does not distract from lessons or lectures. If necessary, everyone adjusts their schedule independently. This is not a required setting, but one of the functional features.

1. Enable the Ok Google command in Google Assistant

Google Assistant is a modern assistant. Using the “OK Google” command, you can voice a request to the system, and it will return the desired page. For example, “Okay Google, what is the weather in Moscow now?” The search results are below in the picture.

1. Enable photo backups in Google Photos

Backup is the creation of an image of files so that if they are lost, they can be restored. The Google platform offers to use Google Photos as a virtual storage system.

With certain settings, any photo taken on the phone is placed in the Google Photos folder. Further, even if you erase the image from your phone, it remains in the Google storage memory. The only downside is that the cloud space is limited - 15 gigabytes. To protect yourself from losing important information and pictures, install regular backups.

1. Install the necessary applications

The next step is downloading applications. Since you are already logged into Google Play, go to the application store and select the ones you need. It is better to download software via Wi-Fi.

1. Choose your default apps

Next, the system will ask you to choose which functions you want to use by default. Check or skip this dialog box.

1. Set up mobile data savings

The next step is to activate data saving mode. It allows you to reduce data transfer by not downloading videos, photos and other multimedia on sites at full size.

1. Customize your home screen

Home screen is a space where frequently used applications, clock, weather, and quick access widgets are located. Classically the set includes:

• calendar;
• notes;
• camera;
• gallery;
• call log;
• SMS;
• browser;
• favorite social networks.

You can place them in a convenient order by dragging and dropping.

How to adjust the volume using the engineering menu

Reducing or increasing the speaker volume is indeed possible using this functionality. To make changes to the default settings, you need to do the following:

• Technical characteristics 5.45″ Smartphone Honor 7S 16 GB black. DNS online store

• Enter the required code/password to go to the engineering menu;
• Through “Hardware Testing” go to the subsection called “Audio”.

Now you need to pay attention to the following two options:

• The first allows you to adjust the volume for the standard phone speaker. It's called “Normal Mode”;
• The second, called “Headset Mode,” provides similar capabilities, only for sound transmitted through connected headphones.

What's next:

• Initially set the “Media” parameter in the “Type” field;
• And in the “Level” field – “Level 0”;
• The volume level itself is set in the “Value” and “Max. Vol."

The maximum permissible value is 225. When initially set to zero. It is advisable to remember the initially set parameters in order to return to them if necessary.

Screen calibration

Calibration begins after using simple instructions for use:

• launching the “Phone” program;
• enter code *#*#3646633#*#*;

• upon opening the engineering menu, click on “Hardware Testing”;

• Activate "Sensor".

• go to “Sensor Calibration”.

• click on “Clear Calibration” to clear old sensor settings;

• select “Do calibration 20%” to set the display sensitivity level;

To finish, click on “Back” or “Home”. Reboot your device.

Information alternative – Project Menu

In some phones, the manufacturer decides to abandon a full-fledged engineering mode, believing that it has no use for the average person. Sometimes, instead of it, after entering the appropriate password, an alternative appears - Project Menu.

What is the difference? It lies in the fact that Project Menu is purely informational in nature:

• Battery Charge. A section that allows you to obtain information about the charge level of the battery used, the degree of its heating;
• Network Information Query. Provides information on the SIM card, the country where the smartphone was produced;
• Veneer Information. Various information about the OS version, other built-in programs, manufacturers.

However, there are a couple of sections that allow you to perform certain actions:

• Restore Factory. Used to roll back the phone settings to the original factory settings;
• Software Upgrade. Provides the ability to upgrade the software used;
• Background Settings. You can change the color of the theme used, debug the operation of the USB port, if there is one, and change some other characteristics.

In general, if there is no full-fledged engineering mode, then some tools can be obtained using this somewhat truncated version.

Alternative launch method

The most common reason is an incorrectly entered service command. But the manufacturer may intentionally close the engineering menu. Then an alternative can help - entering a special command to open the Project Menu, which is only available on some Honor and Huawei phones. To enter, enter the secret code in tone mode: *#*#2846579#*#*.

The following device data is available through the Project Menu:

• battery status: charge and discharge rate;
• SIM card information;
• country of assembly and release;
• information about the OS and downloaded utilities.

Through the Project Menu, unlike the engineering menu, you cannot access to change the functions of the phone modules. But you can easily identify energy-consuming utilities and then disable them in the application manager.

The engineering menu allows the owner to access almost all parameters of the smartphone: from the motion sensor to the GSM signal. Many developers erase it after final diagnostics before putting it up for sale. But if the engineering menu remains, just dial the service code to access detailed configuration about the device.

Another alternative is engineering codes

Such codes were already implemented in old phones that did not have the ability to display detailed graphic information on the screen. A visual interface is absolutely not needed to use them.

There are a lot of engineering codes. We decided to provide information about those that are used most often (you can search for others on specialized Internet portals):

• *#06#. Used in a situation where you want to find out a reliable IMEI address;

Reviews from people

Do owners of Honor and Huawei smartphones use engineering mode in everyday life? Let's find out from their reviews:

1. Anton. I have Huawei P20. After six months of use, the sound began to disappear. I answer people, I hear them worse and worse. Cleaned the speaker. Did not help. Thanks to access to the engineering mode, I was able to correct the situation completely on my own, without resorting to the help of paid specialists.
2. Regina. A friend of mine gave me a Huawei Y5 II. I like the phone, but I wasn't initially happy with the camera. I gave it to a friend. Using this menu, he was able to reconfigure it so that I started to like everything. So this is a very useful feature.
3. Vladimir. I tried to access this menu from my Honor 7A Pro. But I couldn’t, unfortunately. Well, okay, I’m guaranteed not to mess it up there!
4. Igor. I learned about this opportunity a long time ago. Naturally, I also found out the access code for my Honor 9 lite. I'm entering. Don `t come in. I tried it five times. But now I’ve learned that you can’t copy – you just have to enter it manually. I tried it now. It turns out that everything works great. Thanks for the info!
5. Oleg. I don’t know why, but on my Huawei Y3 only Project Menu launches. Maybe I'm using the wrong passwords? I seem to be entering it carefully. Or some special version of my gadget.
6. Marina. I have a simple Honor 10 lite. But I really like the smartphone. For me personally, this is the ideal phone, with the right settings. That's why I didn't even try to change anything about it. I know that I will only make everything worse.
7. Yaroslav. It runs on Honor 8X without any problems. The engineering menu really provides a lot of information and opportunities. True, I’m still studying everything carefully. Then I will experiment. In fact, it can be adjusted so that even no additional firmware is needed.

It is important to understand that the engineering menu was not initially intended for active use by ordinary people. Therefore, if you decide to take advantage of its capabilities, you should think in advance about the likely consequences of the changes made, and also clearly understand the purpose of this or that action.

Now we’ll tell you how to enter the Honor and Huawei engineering menu and access various settings that are not available in the regular menu.

For example, you can find out the battery temperature or system software version numbers.

Login code for Honor

To enter the Honor engineering menu (Project Menu), you must:

1. Open a standard application for making calls (in other words, a “dialer”)
2. Enter the code *#*#2846579#*#* (a menu will open as in the picture below)
3. If the engineering menu does not open immediately, you need to press the call button.

This code is suitable for all modern Honor models and has been tested on Honor 7a,8,9,10 and Honor 20 Pro.

Attention! If you are not sure what you want to do in the engineering menu, it is better not to go there, otherwise you may disrupt the system or accidentally reset the settings to factory settings with the loss of all data - applications, photos, contacts and games.

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 photo format. In the menu, find the Camera item 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.

Huawei is a smartphone manufacturing company that has recently demonstrated the fastest growth dynamics in the world. The number of Huawei Honor smartphone users in many countries is steadily increasing. And in this situation, on all Internet forums dedicated to Android phones, the number of questions related to the problems faced by Huawei Honor owners is growing.

Almost all Android OS users know that their phones have a hidden “engineering menu” with which you can test or adjust certain settings of the device modules.

Go to the Huawei service menu

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 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 operation of your smartphone or tablet.

1. To access the service menu, you need to know a special code that is suitable for certain brands of devices. For Huawei or Honor mobile gadgets, there are two code combinations:
   *#*#2846579#*#*

   *#*#2846579159#*#*

2. To enter the code, open the digital dial pad on your device and enter one of the above commands. Usually, when you click on the last character, the menu opens automatically. If this does not happen, tap on the call button.
3. If the operation is successfully completed, an engineering menu with six items will be displayed on the screen, which contain information about the device and make it possible to make more detailed settings.

Now you can independently change the settings of your gadget at a professional level.

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 not-loud-enough speaker or camera experimentation is worth it. We are glad that we were able to help you solve the problem. Describe what didn't work for you. Our specialists will try to answer as quickly as possible.

Huawei is a smartphone manufacturing company that has recently demonstrated the fastest growth dynamics in the world. The number of Huawei Honor smartphone users in many countries is steadily increasing. And in this situation, on all Internet forums dedicated to Android phones, the number of questions related to the problems faced by Huawei Honor owners is growing.

Almost all Android OS users know that their phones have a hidden “engineering menu” with which you can test or adjust certain settings of the device modules.

What options are available in the engineering menu

In fact, the set of options that are included in Engineering Mode on different Huawei Honor phones may vary. Let's look at its standard points:

• Telephony. This item provides for managing the parameters and ranges of the mobile network to which the phone is connected. Here you can also check whether a particular device can work in the cellular operator’s network, etc.
• Connectivity. This section checks the operation of wireless modules, configures how to turn off the display when using the Wi-Fi Display function, etc.
• Hardware Testing. Already from the name it is clear that the main purpose of this set of options is the ability to test various hardware units of the phone. The user can check and increase the volume of sound coming from the built-in speaker or through a connected headset. You can check the screen, sensors, etc.
• Location. If you need to disable or, conversely, enable A-GPS detection, you can do this in this section.
• Log & Debugging. Here are links to test utilities from both MediaTek and other component manufacturers.
• Others. Another section with settings. In particular, here you can adjust the size of the fonts used in the phone.

In addition to the basic options listed above, the engineering menu has additional functions. With their help, you can, if necessary, change the phone's mac address and IMEI, optimize the settings of the camera module, Bluetooth, Wi-Fi, CPU, and obtain detailed information about the operation of the battery.

Wlan, GPS and bluetooth:

How to enter the engineering menu on an Honor phone

In order to enter the engineering menu, you need to open the “Phone” application and enter one of the codes below in the dialer field:

*#*#2846579159#*#*

*#*#2846579#*#*

*#*#2846580#*#*

It is important to note that not all Huawei Honor smartphones “pass” the user who has entered the service code in Engineering Mode. The phone must be equipped with a MediaTek processor. Honor models include Honor 4C Pro, 3X Pro, Holly, 8A Pro, 7A, etc.

Codes for running various factory tests:

* # * # 0283 # * # * – Packet Loopback.

* # * # 0 * # * # * – LCD display.

* # * # 0673 # * # * OR * # * # 0289 # * # * – Melody test.

How to increase the sound volume in the phone speaker through the standard engineering menu

The problem of sound volume in the phone speaker is not that uncommon. If you cannot solve it using means open to the user (standard settings, Huawei Histen, etc.), you need to do this through the engineering menu:

1. Dial the code *#*#2846579#*#* or *#*#2846579159#*#*.
2. We need the “Hardware Testing” service menu, “Audio” section.
3. Audio offers two options to adjust audio volume

“Normal Mode” – sound supplied through the built-in speaker

“Headset Mode” – sound supplied through connected headphones

1. For “Normal Mode”, select the “Media” parameter in the “Type” field, and “Level 0” in the “Level” field. This is the zero value, from which you can then begin adjusting the volume.
2. To adjust the volume, set the values ​​in the “Value” and “Max” fields. Vol." The maximum value is usually 225.

What is Project Menu

Very often, after entering the appropriate code, the Project Menu opens on the Honor screen.

Project Menu on Huawei phones is a stripped-down analogue of Engineering Mode, which has the following sections:

1. Background Settings: debugging mode, USB port setting, changing UI theme color;
2. Veneer Information (vendor information): information about versions, manufacturer, etc.;
3. Network Information Query: information about SIM blocking, country of manufacturer, etc.;
4. Software Upgrade: Perform a software update
5. Restore Factory
6. Battery Charge: Displays the current battery charge level and temperature.

You won't be able to test and configure phone modules through this stripped-down menu. Perhaps in such a situation, using service codes that are entered through the dialer will help; there is no need to enter Engineering Mode or the Project Menu.

Additional features on Honor and Huawei

For some Honor and Huawei smartphones, the manufacturer has provided a Project Menu, which is an alternative to Engineering Mode. Information is displayed here without the ability to adjust certain parameters. Let's look at what sections there are in the Projec Menu and what they are responsible for.

Backgroundsettings

Here USB debugging is carried out and some other characteristics are changed. It’s disappointing that the menu is not in Russian, so it’s worth using a translator.

Board Information

This item is responsible for all kinds of information about the installed operating system, shell and programs.

Network

Here you can find information about SIM cards and the place of manufacture of your mobile device.

SoftwareUpgrade

This section allows the user to update the software to a new version.

FactoryReset

You should be extremely careful with this point, because when you click on the “ OK” , the phone will be rolled back to factory settings and all third-party data will be deleted from it.

IncreasePower

Information about the battery status is displayed here. For example, battery temperature and remaining charge.

You can close the Project Menu by clicking the Back .
