How To Enter Huawei Engineering Menu

One of the advantages of mobile phones running on the Android OS is the ability to make finer settings for various functions available on a particular smartphone model. Naturally, similar features are available for owners of mobile phones from Huawei or Honor.

For this purpose, a special engineering menu is used. In this article, we will figure out why such a functional is generally provided, how to get access to it, what exactly can be done with it. For example, how to increase the sound through the engineering menu of Huawei.

What is this functionality intended for?

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

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

Naturally, the same capabilities are often used by specialists of various service centers to bring 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 harm the purchased equipment, thoughtlessly making any changes to its work.

Therefore, before entering the engineering menu of Huawei or Honor, you should think several times. will you do irreparable harm to your gadget?

How to get access?

It is logical that such access cannot be obtained through the standard phone menu. Then how to enter? For this purpose, special commands are used. 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 Huawei usually uses, which also produces Honor smartphones: ## 2846579 ## or ## 2846579159 ##.

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

  • You should not even try to copy or use the password by writing it to the phone book. It will not work! Manual entry only. The developers specifically made it so that the user was fully aware of their actions. For example, this is a guarantee that the child does not accidentally go into the engineering menu and do not change the settings;
  • Almost always, after entering all the necessary characters, an automatic transition occurs. But some manufacturers made the team work only after additional use of the call button.

Options available in Honor and Huawei engineering menus

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

  • Telephony (Telephony). Used to diagnose the mobile networks with which the device works. You can check and configure the available ranges, network parameters of a particular operator;
  • Connectivity The section is designed to assess the functionality of the so-called wireless modules. For example, you can configure features such as Wi-Fi Display;

  • Location Allows you to connect or disconnect the ability to track location using A-GPS;
  • Log Debugging The section provides access to the links of special debugging utilities that are used by manufacturers;
  • Others. A lot of interesting things were also placed here. For example, in this section you can change the font used in the display on the screen of a mobile phone.

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

What is included in the sections described above? In more detail, then the following tools:

Telephony

How to adjust the volume using the engineering menu

Decreasing or increasing the speaker volume is really possible with this functionality. To make changes to the default settings, do the following:

How To Enter Huawei Engineering Menu
  • 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 a standard sound speaker phone. It is called “Normal Mode”;
  • The second, called “Headset Mode”, provides similar capabilities, only for sound transmitted through plug-in headphones.
  • Initially set the “Media” parameter in the “Type” field;
  • And in the field “Level”. “Level 0”;
  • The volume level itself is set in the “Value” and “Max. Vol. “

The maximum allowable value is 225. When initially set to zero. It is advisable to remember the initially set parameters so that, if necessary, return to them.

Information Alternative. Project Menu

In some phones, the manufacturer decides to abandon the full-fledged engineering mode, believing that the layman has nothing to do with it. Sometimes instead of it, after entering the appropriate password, an alternative appears. Project Menu.

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

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

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

  • Software Upgrade. Provides the ability to upgrade the software used;
  • Background Settings. You can change the color of the theme used, debug the USB port, if any, change some other characteristics.

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

Another alternative is engineering codes

Such codes were introduced even in old phones, which did not have the ability to display detailed graphic information on the screen. A clear interface for their use is absolutely not needed.

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 situations where you want to know a valid IMEI address;
  • ## 4636 ##. It allows you to get some statistics. About the device itself or its battery;
  • ## 7780 ##. Rolls back the OS settings to the original. Similarly, it returns factory settings for applications installed on the phone, Google Play services;
  • 27673855 #. After entering this command, the mobile phone will be fully formatted. It is only necessary to use it after having thought everything over and clearly understanding the consequences of such an action;
  • ## 34971539 ##. The owner of the phone to get important information related to the functionality of the built-in camera;
  • ## 7594 ##. Allows you to make adjustments to the settings of the button mode, which is responsible for turning off and on the mobile phone;
  • ## 273283255663282 ##. Lets you go to the backup tool
