Android wifi engineering menu. Entering the engineering menu on Android (command and program)

Companies that create Android smartphones, including Lenovo, implement and use engineering menu.

In Lenovo engineering menu ( Engineer Mode) contains a variety of settings and gadget testing options that are not available to ordinary users. But now, having downloaded special application from the Play Market, or knowing the special USSD command, any user can enter there.

The engineering menu is a special special application that is hidden from the eyes of the average user and is used by developers to test and set the necessary parameters. It allows specialists to check the operation of various sensors and adjust the operation of system elements.

If you decide to enter the “holy of holies” of developers, then when working with the technical menu of the Android OS, be extremely careful: an error when changing functions can lead to various malfunctions in the operation of the device.

How to enter the menu?

Don’t know how to access the engineering menu on Lenovo? To log in, you must enter numbers, as with standard dialing of a telephone number. After this, you will need to dial a certain combination consisting of signs and numbers. It is necessary to take into account that this combination Each smartphone creator has his own. In addition, it also depends on the planned adjustments in the Lenovo menu.

Combinations to launch Engineering Mode

For Lenovo smartphones operating on the MediaTek chipset (as well as for other gadgets Chinese manufacturers), to get to the technical menu, you need to enter one of the combinations:

  • *#*#3646633#*#*;
  • *#*#54298#*#*.

If any of the above special codes do not work, then you should use third-party applications; you can even download them on the Play Market. It is best to use applications such as Shortcut Master, Mobileuncle Tools in such situations.

Video “How to work in Engineering Mode”

We suggest watching the video before taking any action yourself.

Please note that Engineer Mode does not function on certain models smartphones running Android 5.1 Lollipop. In addition, it is not valid when using the Cyanogenmod firmware.

When you reboot into Android 4.4.2, the changes made in the special application are subsequently reset.

Mobileuncle Tools program

The functionality of this application is almost the same as that of the engineering menu called special code, with the only difference that here the user is given the opportunity not only to familiarize himself with data about the memory, sensor and display of the device, but also to update the firmware and improve GPS.

To work with this program you need root rights (root).

Shortcut Master utility

This program was created specifically to delete, search, create. It does not contain functions for entering Engineer Mode. However, through it you can get acquainted with the list of secret special commands operating on the device. After clicking on the team name, the command “ Execute" This is a very comfortable way of working; you don’t need to do any extra steps.

To view the list of available codes, in the Shortcut Master program you should call up the auxiliary menu by clicking on the item “ Secret Code Explorer».

Root rights to access the engineering menu

To enter Engineer Mode in certain versions of Android, you must have special root rights. You can obtain these rights through special programs such as UniversalAndRoot, Farmroot and others.

To access the gadget via Farmroot, you should:

  • Install and launch the application;
  • If the program supports installing root rights on your device, then a list of available actions will appear on the display, including "Get root". Click on this item;
  • Select one pre-installation method for obtaining rights;
  • The installation will begin;
  • After the installation is complete, a message will appear indicating that root access has been established.

What can you customize in the menu?

In Engineer Mode, the settings of existing cameras, sound, and recovery mode are often adjusted. In this case, you need to be extremely careful, because the names of items in various device models can differ significantly.

Adjusting sound parameters in the engineering menu

If the ring volume level of your gadget is not acceptable for you, find a section in the engineering menu called "Audio" and go to "LaudSpeaker Mode". There click on "Ring". Change the existing signal values ​​- in the section "Max" increase the value "Vol"(limit value - 200). Click on the key "Set".

To enhance the tone conversational dynamics follows in section "Audio" choose « Normal Mode» and go to "Sph". Set the signal values ​​from minimum 100 to maximum 150.

In order to increase the sensitivity of the microphone, you should go through "Audio - Normal mode - Mic". At each level, the same microphone sensitivity indicators are set. Click on "Set", reboot and check if the other person can now hear you better than before.

Disabling unused frequencies

Modern smartphones are very “gluttonous” and quickly consume battery power to ensure the functioning of applications. Using Engineer Mode, you can significantly increase the battery life.

Gadgets are capable of scanning GSM frequencies - 1900/850 MHz, 1800/900 MHz. The last pair operates on the territory of our state, which means that there is no need to scan the network at other frequencies. For an unnecessary pair, the signal can be deactivated so that less battery power is consumed.

In the engineering menu, go to "Band Mode". Deactivate frequencies that you do not use by unchecking GSM850 and PCS1900. If the device supports a pair of SIM cards, then you should open the SIM2 and SIM 1 sections in turn, and then carry out the specified actions in each of them. To save the new settings, click on "Set".

Camera

By default, Android smartphones are able to save photos in JPEG. But most photographers prefer to take photos and process the material in RAW for greater editing capabilities. The technical menu allows you to select the optimal photo format.

In the engineering menu you should find the section "Camera" and select the type of image there. In addition, in the camera menu you can increase the size of photos, set the ISO value, activate shooting in HDR format to increase the detail of images, and set the frame rate for videos. After changing each of the parameters, you should save the new settings by clicking on "Set".

Recovery Mode

Recovery mode is an analogue of Bios on a PC. It makes it possible to control the device without logging in. There are the following recovery options:

  • Removing personal information from the system;
  • Creating backup copies of the operating system;
  • Access to root rights;
  • Firmware update;
  • Reset existing settings to initial ones.

In recovery mode, you shouldn't take actions unless you have confidence in what they can ultimately lead to. Certain commands can cause significant harm to the system and device.

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 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 already quite convenient Huawei phones can be made even better with the help of fine tuning"for yourself." 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. Engineer mode is usually used by developers at the final settings device before it goes on sale. With its help, they check the device for the presence various errors, malfunctions, and also check the functionality of all device systems. In addition, in the engineering menu there is 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 intentionally 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.

Engineering menu for Huawei smartphones It's usually always there and never removed, so if you didn't get to 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 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 prerequisite To trigger the code it is necessary to enter it manually.

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 the so-called “ service codes", which partially repeat 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 apparatus. 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 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 set. However, due to the rather 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.

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.

That's probably all, dear friends. We hope this article was useful to you and answered most of your questions. We wish you excellent setup of your phone, and may it bring you only pleasant emotions.

Let's look at the features of the Android engineering menu various manufacturers, what is it for, how to use it and what useful features this menu carries for you.

This article Suitable for all brands that produce phones running Android 9/8/7/6: Samsung, HTC, Lenovo, LG, Sony, ZTE, Huawei, Meizu, Fly, Alcatel, Xiaomi, Nokia and others. We are not responsible for your actions.

What is the Android engineering menu?

Engineering menu (Engineering Mode) is special application, which is available on almost every gadget. It is used by the manufacturer for various tests and optimization of sensors, functions and other parameters of a tablet or phone. This menu is hidden in the system by default so that the user cannot access it.

As a rule, the engineering menu is called up using a small code that is entered on a standard dialer. It can be accessed by using third party programs.

The engineering menu is hidden due to the fact that careless use of its capabilities can lead to damage to the device. Please be careful when making any changes.

How to enter the engineering menu on Android

A secret application cannot be launched through the regular interface. You can enter the engineering menu this way:

  • Open the calls window to enter a phone number using the keyboard.
  • We write a special combination of characters.
  • If immediately after entering the code this menu does not start, press the call button.

Each manufacturer has its own combination of symbols, which contains Special symbols(*, #) and numbers. For example, for Samsung phones the engineering menu is launched with the following sequence: *#*#4636#*#*. The screenshot below shows codes for different gadget manufacturers.

If nothing happens after entering the code, use applications from Google Play that work with the engineering menu. For example, the MTK Engineering Mode application, which is a complete copy of the standard engineering menu. Most of them will require root rights to the device, without which the software will function with errors, and some parameters will be inaccessible.

Mobileuncle Tools

The program has advanced features. Can be viewed and edited basic settings, update firmware, repair IMEI and improve GPS signal. The utility displays full specifications memory, screen, sensor.

MTK engineering menu

Program for gadgets with MediaTek processors. Loads successfully engineering functions, but there are errors with saving parameters. They may reset after a reboot.

  • If the utility supports installing root rights on your gadget, then the “Get root” option will be displayed on the screen. Select this item.
  • From the preset methods for obtaining root, select one.
  • The software will begin installation.
  • After completing the procedure, a message will be displayed indicating the successful installation of root access.

Possible errors and solutions:

  • Root rights are not installed - try another method (select a new exploit in the application).
  • The application closed mid-installation. The user needs to restart the device and try again.

Engineering menu functions

The engineering menu is divided into several categories. Let's look at each of them separately:

  • Telephony. This category contains settings that relate to mobile communications. For example, you can disable or enable certain BandModes ( different frequencies for 2G/3G/4G operation), disable in background data transfer or check the operation of SIM cards.
  • Connectivity. Setting up Wi-Fi, Wi-Fi CTIA, radio, Bluetooth settings. In the settings you can specify the type of antenna (you must use headphones), radio wave, sound format (stereo or mono). Directly from this section the radio will play.
  • Hardware Testing. Here you can configure the work different components device: sound levels of speakers and headphones, microphone sensitivity, different camera parameters (focus, HDR, ISO adjustment, photo aspect ratio and much more), sensor operation (calibration), touchscreen, etc. This category is quite global and large; you need to understand all sections and have skills and serious knowledge.
  • Location. In this category it is customizable GPS work, you can conduct testing and see the number of satellites found.
  • Log and Debugging. This category contains logs of the battery (charge percentage, temperature, operating time, voltage) and other functions that to a simple user little known.
  • Others. Contains two functions that are unknown to most users.

Engineering menu settings

The options for adjusting parameters and the appearance of the engineering menu may differ depending on the model of smartphone or tablet. Users most often use the menu to adjust the sound, change the camera settings and use the recovery mode.

Volume Boost

If your gadget does not ring loudly enough, then in the engineering menu you need to find the Audio item and go to LoudSpeaker Mode. There we select the Ring tab. For all signal levels (1 – 6 Level) we change the values. The numbers are arranged in ascending order.

In the Max. Vol. increase the value to the maximum. To save the settings, press the SET button.

Increasing the volume of a telephone conversation

To increase the speaker tone during calls, select Normal mode in the Audio service menu, then open the Sph section. For signal levels (1 – 6 Level) we set values ​​from 100 to 150, and Max. Vol. – 160.

In the Audio menu you can increase the microphone sensitivity. To do this, select Normal mode, then Mic. For all levels we assign the same microphone sensitivity value. Press the SET button, then reboot and check whether the interlocutor can hear you better.


Advanced users modern smartphones and tablets use numerous functions that the Android engineering menu has. It allows you to get information about the mac address, check or configure Wi-Fi work, Bluetooth, update software cameras, speakers. Very often, using such a menu you can improve the sound on your device and make other fine adjustments. For example, return the original settings Google account, specify settings for blocking and turning off the device, set settings that allow you to create a backup copy important information. Before entering the engineering menu, you need to understand that rash actions can lead to a malfunction of the device. It is advisable for the user to remember what changes were made to the system in order, if necessary, to return all settings to their previous state.

How to enter the engineering menu using the standard capabilities of the device?

List functionality can be opened by typing a certain combination of characters in the device's call window. The Android engineering menu code varies depending on the brand of phone or tablet. Each manufacturer sets its own combination. Such information is usually indicated in the instructions for the phone and on official websites. For users modern devices Usually there are no difficulties in finding the required code.

Below we provide a table of the most common combinations. It is not recommended to use them unless your device is one of the listed brands.

The developers do not recommend executing such commands without certain knowledge and experience. But often only this method helps to quickly solve a number of problems associated with returning the device to original condition, receiving additional information about the device. The engineering menu is presented in English, which makes it understandable for most users.

Using additional programs

It is not always possible to find out the combination that is suitable directly for your device. In such situations, you can install special software on your mobile device, which will allow you to open a list of the functionality of your smartphone or tablet with a few clicks. It is publicly available to different versions Android and device models.

The program for entering the Android engineering menu can be installed via a USB connection to personal computer or laptop. One of them is called Mediatek Engineer Mode. It is a file EnMode.apk, which must be transferred to the device memory and installed in the usual way. This program is suitable for devices operating on the MTK processor. The user has the opportunity to download free and paid version BY.

IN Google store Play there is an opportunity to download the Mobileuncle utility MTK Tools. It is designed for smartphones and tablets running Android 2.1. and later versions. The description says that similar utility also suitable exclusively for devices equipped with an MTK processor.

The Mobileuncle Tools program is suitable for owners. There are other utilities, for example, Shortcut Master, engineering MTK menu, launching the MTK engineering menu. Before installing them, we recommend that you read the application rating, reviews from other users, and also check your device for compatibility.

Setting up optimal sound by opening the engineering menu

One of the most common reasons The reason why users are looking for information on how to enter the engineering menu is the need to fine-tune the sound. The following situations may arise:

  • Poor audibility when the speakerphone is on
  • Sudden changes in sound when incoming call while listening to audio
  • Insufficient signal volume
  • Quiet sounds while recording video
  • Quiet operation of the headset and microphone.

This is just a small list installed settings, which can be changed through the engineering menu of a modern mobile device. Sound settings are done via Audio section, which is displayed immediately after entering the menu. Then the screen will appear various tabs, for example, Headset Mode. This tab allows you to set sound parameters that are activated when you connect a headset. Normal Mode sets the sound in the normal state of the mobile device (without connecting headphones or speakers).

LoudSpeaker Mode tab, which are activated when the loudspeaker is turned on. Headset LoudSpeaker Mode allows you to make settings for active mode speaker while a headset is connected to it. The Speech Enhancement tab provides settings that come into play when communicating over a mobile network.

In any of the modes, you can fine-tune the microphone or increase the volume (see table).

The volume of any sound parameter has seven levels - from 0 to 6. The higher the value, the louder your device will sound. We do not recommend installing maximum settings, because it promotes fast . In many devices, setting the volume to maximum can result in unpleasant noise.

The engineering menu is a fine-tuning mechanism mobile devices operating on Android platform. For developers, the list of such features opens up new options when implementing applications. Of course, such a menu is used not only for adjusting sound parameters. It is an essential tool for keeping smartphones and tablets running optimally. But it's best not to make changes you're not sure about.

Engineering menu on phones with operating system Android system gives access to advanced features and settings. Advanced users smartphones prefer to use the engineering menu for more comfortable operation. On many Chinese-made smartphones, the mode is available by default. In other cases, users have to get to the settings themselves.

Why it may not be possible to enter the engineering menu

If the user does not have such a mode on his smartphone, most likely he has no default access to the engineering menu. This problem can be solved. There are special USSD commands and applications that allow you to access advanced device customization options.

Login using code

The codes for entering the engineering menu are similar in structure to USSD requests. Many smartphones use universal codes, while others have special codes provided by a specific manufacturer.

CodeManufacturer
*#*#3646633#*#* Universal
*#15963#* Universal
*#*#4636#*#* Universal
*#*#54298#*#*, *#*#3646633#*#* Processor MTK
#*#8255#*#* , *#*#4636#*#* Samsung
*#*#3424#*#*, *#*#4636#*#* , *#*#8255#*#* NTS
*#*#7378423#*#* Sony
*#*#3646633#*#* Alcatel, Fly
*#*#3338613#*#* , *#*#13411#*#* Alcatel, Fly, Philips
*#*#2846579#*#* , *#*#2846579159#*#* Huawei
*#*#2237332846633#*#* Acer

As soon as the user enters the code combination, the engineering menu should open. Codes are entered in dialing mode; there is no need to press the call button.

Installing a third party application

In rare cases, the codes do not work. You can try to install third party application or program, with their help to gain access to the engineering menu.

Launching the MTK engineering menu
