Modern smartphones are not only about making calls, surfing the Internet and experiencing various games. Devices running Android OS have a fairly large number of different secrets and extensions. Some of them are available in the engineering menu. But what is it? How to log in engineering menu? Are there any risks in working with this part of the gadget's firmware? Let's start by asking why this menu is not publicly available.

Safety

The fact is that everything that the user has access to, even if mistreated and removed, will not bring irreparable harm to the smartphone. The same menu, if used incorrectly, can lead to the fact that the gadget will not differ much from a simple tin can, the place of which is in the trash can.

In addition, everything that a user really needs is always in the public domain. Hidden functions more intended for those who are professionally engaged in software repair of smartphones. By the way, many masters recommend taking a piece of paper and a pen before entering the Android engineering menu. For what? To write down all the stock data, just in case. It helps a lot when something goes wrong.

What is this menu?

The engineering menu means special program, used by developers at the end of the formation of the gadget software platform. It helps at the final stage to change the performance of the device and adjust its various functions at the software level. This menu is also used for testing.

Before using this menu, you should make sure that your smartphone runs on the MediaTech processor. Why is it so important? On other chipsets, for example, Qualcomm, the engineering menu is noticeably curtailed and may be absent altogether. How to enter engineering Samsung menu, there is no question at all, since all devices of this brand work on other types of processors.

Android version

Is there a difference between how to enter the engineering menu "Android 5.1" and a younger one or old version platforms? Note that there is a difference even in brands and models of gadgets. As mentioned above, there is no entry to the engineering menu for Samsung, although some argue that the following commands work in this case: * # * # 8255 # * # *, * # 0011 # or * # * # 4636 # * #.

How to open the menu

And now we come to the main question: how to enter the engineering menu? This is possible by entering a special code. This can be done through the dialer. What should I enter?

  • *#*#3646633#*#*
  • *#*#4636#*#*
  • *#15963#*

After entering the command, most smartphones are automatically redirected to the engineering menu. In rare cases, you need to press the call button. If nothing happens after that, check the input is correct. If there is no error, but there is no result either, then the entered code does not suit you.

In the event that you have a tablet that does not have a dialer, or none of the codes worked, you can download a special application from the "Market". For example MTK Engineering or MobileUncle Tools. The apps are free.

Functional

After you managed to enter the engineering menu, you need to find the department for which all the procedures described above were done. There are three options to test and determine any metrics. Let's figure out what's what.

Camera

Let's start with this part of the gadget. Almost all camera parameters can be configured through the engineering menu. In another mode, you can turn it on to determine the indicators of the operating current. Few people are interested in this, but in some cases it helps to solve certain problems associated with auto-correction or focusing.

Audio

Often, the question of how to enter the engineering menu of the phone is of interest to the user precisely because he wants to make his gadget louder. If the manufacturer has not set the maximum settings, you can independently adjust the sound both in the speakers and in the microphone.

These operations can be performed in several separate modes:

  • Sip. This item is intended for setting up calls via the Internet using convenient parameters.
  • Mic. In this section, you can change the sensitivity of the microphone to either side, for example, to prevent the microphone from catching breath, and so on.
  • Sph. This section is responsible for ear speaker... It is recommended to use it if you have difficulty hearing interlocutors calling from different devices, and adjusting the volume rocker does not help out.
  • Sph2. Not every smartphone can use this feature, as it is intended for a second hearing speaker.
  • Sid. It is better not to change this parameter, since it is almost impossible to adjust it correctly again. He is responsible for the echo effect.
  • Media. Use this section if you are not satisfied with the media volume level. Here we are talking about music, video and so on.
  • Ring. The name of this parameter speaks for itself - the ringtone or the volume of the incoming call.
  • FMR - radio sound tuning.

When working in each of the sections, you should understand that you should not play with each of the parameters.

Connections

In the connections section, you can test and correct all possible types of connections that are in the gadget. These include Bluetooth and Wi-Fi. Apart from these obvious types wireless connection, you can check how well and stably the WLAN CTIA and even the FM receiver work.

It is curious that in a separate section "Disabling detection" you can adjust the signal frequency.

Display and touch screen

These sections will help you test and set up your smartphone screen and backlight. The first is responsible for backlight correction, control of display lines, and backlight adjustment. By adjusting the sensor, you can test it for broken segments, reaction to touch, and so on. You can also calibrate the sensor through the engineering menu.

Memory and USB

The question of how to enter the engineering menu is also asked by those who are faced with the disappearance of memory on the device. By the way, in a separate section you can test the SD card. As for the memory of the gadget, the menu contains all the information about the module. In the engineering menu, you can test the performance of the USB port.

Battery

This section is searched by quite a few and are upset when they do not find it. Maybe he is not in the engineering menu? In fact, you can see the status of the battery, the percentage of its deterioration and the rating of the processes that most affect the device, you can in the section "To the extent" and in the "Battery log". The reason for this strange name is the incorrect translation from English. By the way, there is simply no transition from Russian to any other language in the engineering menu.

Qualcomm

As mentioned above, in most devices with such a processor, the engineering menu does not work or is significantly reduced. You can get into it through the usual menu. In it, you need to click on the item several times in a row, which is referred to as the "Kernel version". It will open to you new function, which contains five separate items. Which ones?

  1. Automatic Test. Fully corresponds to its name, it conducts automatic testing of all necessary systems.
  2. Single Item Test. This section allows you to choose one of 25 tests.
  3. Test Report. By clicking on this option, you will be able to view the test reports.
  4. SW add HW version consists of various numbers that display smartphone data.
  5. Device View. Here is information about the equipment.

Not all Qualcomm-powered smartphones will display just such a menu, but it's worth a try.

conclusions

Knowing how to enter the engineering menu "Android 4.4" and other versions of this operating system, it should be understood that if one of the settings causes the gadget to malfunction, the ability to restore it becomes very small. Therefore, as soon as you decide to change something in the settings through the engineering menu, be aware that the life of the device may end there. If something does not suit you in the work of the gadget, it is better to contact an experienced craftsman and describe your wishes in detail. He will be able to soberly assess the possibilities and make a verdict.

Buying a new smartphone or tablet is a real treat for many. Each owner expects that the gadget will please for many years with its reliable operation and the absence of any problems. Moreover, regardless of who the assembler is and what control system is installed.

However, as often happens, modern mobile devices can hardly be called ideal, since after a while after the start of use, moments are revealed that the owner wants to fix, in one way or another, modifying the software part of his mobile assistant to the ideal. Of course, in my understanding. One of the available tools is the Android engineering menu.

Secret settings everyone knows about

At the final stage of configuring the software component of the gadget, running under the control of the system from "Google", the developers use the so-called engineering menu "Android". a special program that allows you to make adjustments to the operation of the device, perform technological tests, view information from sensors. Since thoughtless use of this tool can lead to unpredictable results, most often access to it is hidden from users. However, in fact, the secret is already known to everyone - in order to learn how to call the mentioned menu, it is enough to devote just a few minutes to search for recommendations.

Several important points

Nevertheless, not all mobile devices can enter the Android engineering menu. In order to take advantage of its capabilities, you need to make sure that the gadget meets certain requirements.

Firstly, CPU must be necessarily produced by MediaTek (or MTK). On inexpensive Spreadtrum models, for example, the SC-6825, the popular Snapdragon from Qualcomm, various Tegra NVidia and Intel, trying to launch the Android engineering menu is useless. It is not there. It will not work even if you prudently install the appropriate application.

Secondly, various modified operating systems, for example, CyanogenMod, popular in some circles, do not allow starting the configuration program, since they were originally developed for devices with a Qualcomm processor that do not support the Android engineering menu. In addition, it is highly desirable that the operating system be original or based on a base.

Thirdly, the application (file) itself must be present among the programs, even being hidden from the standard explorer. So, some manufacturers of mobile devices, after completing the settings of the software part, simply delete the "Android" engineering menu. The description and recommendations for use in this case turn out to be useless, which is obvious.

Secret combination

You can get into the settings of the engineering menu on Android in several ways. It is impossible to say which one is better, as direct comparison is incorrect. Therefore, we will consider them one by one.

One of the most "ancient" options, which was used in the first models of smartphones and tablets, is that the user in the dialer program (the so-called dialer) dials not the subscriber's number, but a special code of the engineering menu "Android" by analogy with checking funds on the account. If the combination is recognized and accepted, the setup application is launched. Some mobile assembly companies apply their own modified code, so standard set doesn't always work. For the rest, to call the menu, you should type the following order of characters without spaces - * # * # 36 46 633 # * # *. It's that simple.

A familiar way of access

Using a secret combination is not always convenient, if only because the order of the symbols is easy to forget. Also, in the case of a changed set, it is easier to use the program, and not to look for the correct order of characters. One of the most famous applications is the so-called Mobile Uncle, or MobileUncle Tools. It is free, so there are usually no problems with finding and installing. At the time of this writing current version is the official 2.9.9 or build 3.1.4, with additional support for some new processors.

In order for the program to work, the user must first obtain root rights on his gadget. There are a lot of applications for this, for example, KingRoot, SuperSu, etc. In this article we will not talk about the nuances of working with a rooted device, since this is a separate voluminous topic. After starting the application, select the third item, named Engineer Mode(both in Russian and in English versions), and in the opened window - "Working with MTK". When prompted to provide root access, you must answer in the affirmative.

How to restore access to Engineer Mode

If the manufacturer of the mobile gadget has taken care of the security of the operating system by prudently removing the configuration program, then it can be reinstalled. To do this, you need to find an installer on the Web that restores EngineerMode.apk and install it.

We do not indicate the exact name due to the abundance of analog clones. For example, one of them is called "Engineering Mode". You can also just copy the missing file to the system folder located in the system \ app path. After that, you can use any method for access: both by dialing a number and by calling directly from the program interface. Note that these operations require

Features of the miracle program

Through the engineering menu, despite the ambiguous attitude of the owners of gadgets to this, it makes it possible to solve several important problems. In particular, adjust the sensitivity of the microphone, cure the "childhood disease" that manifests itself in the insufficient volume of the system speaker, reduce the battery consumption by turning off the scanning of "extra" ranges, and reduce the search time for satellites by the global positioning system receiver. Let's dwell on the above functions in more detail, since they are the most in demand.

Ring volume

It is very easy to increase the ringer volume. To do this, select the "Audio" section with a swipe to the right. A list of modes appears. LoudSpeaker Mode, Ring subsection, is responsible for the system speaker. The parameter in the first window should not be changed, but in the second you can write a higher value. Developers can initially set the indicator to 130, which is quite quiet, but 156 is already close to the limit. The maximum is 160. After editing, you need to press the Set button, located here, and reboot the device, correctly exiting the program.

Frequencies of mobile operators

To optimize energy consumption mobile device communication, you can disable scanning of "extra" frequencies. In our country, when working in conventional 2G / 3G networks, the standard frequencies are 900 and 1800 MHz. The other pair, 850 and 1900 MHz, is the American standard. To enable or disable it, you need to select the Band Mode item, alternately go to the settings for SIM-1 and SIM-2 and uncheck / put the desired marks. Confirmation is made by pressing the Set button.

How to improve GPS? To improve the work, you need to turn on Wi-Fi, select Location in the Android engineering menu, go to Location Based Service and open EPO. Here you need to make sure that there are checkmarks on the Enabled and Download items (if they are present). After that, you should return to YGPS and in the information section, alternately press "Full", "Cold", "Restart". Next, you need to select the "Satellites" item and wait until the answer is recorded (green dots on the map). Everything takes 2 to 5 minutes. After that, it remains to exit the menu, close the program and restart the gadget.

Summing up

The engineering menu of devices operating under control opens up opportunities for the owner of the gadget, the use of which allows you to configure the device in an optimal way. This is often the only way to delay the purchase of a new mobile assistant. This menu is contraindicated only for those who are already completely satisfied with the work of a tablet, navigator or smartphone.

Everyone knows what an advanced user can do with an operating room Windows system wonders. But not everyone suspects that Android has advanced features. An experienced specialist can call up the engineering menu, in which advanced configuration of the device is carried out, as well as testing of certain of its functions. How to enter the engineering menu on Android - read below.

In modern versions of the operating system, there is a fairly complete section " Settings". It can be used to adjust a variety of parameters. But some of them still do not lend themselves to deep customization. Such parameters should be looked for in the engineering menu. For example, specialists from service center can enter the engineering menu in order to adjust the volume of the speaker, headphones and built-in microphone.

In a word, the engineering menu contains system settings that shouldn't be available to the average user. The Android engineering menu can easily ruin a smartphone if you change its parameters almost at random. With its help, you can often even change the font size, increase the number of icons on the desktop, and make other system changes. On some smartphones in the engineering menu, the signal reception strength, the type of vibration and other aspects of the device's operation change.

Interestingly, it is easiest to get into the engineering menu on Android 4.4 and later versions of this OS. The hardest thing to get into this menu is on Android 2.2. Most often, early versions of the operating system were not equipped with an engineering menu at all - that is why they practically did not lend themselves to customization. There are also problems with this on the newest devices.

Fast and easy way

It should be noted that to open the engineering menu, you do not need any third party program... You don't even need root access! You just need to type a special combination on the virtual keyboard - the so-called engineering menu code. The problem is that many manufacturers use their own code, there is no universal combination. Sometimes the code is different even for different models from the same company!

Attention! If you use the engineering menu incorrectly, you risk turning your smartphone into a so-called "brick". If you do not know what this or that parameter does, then do not change it.

First, you should find in the section where the telephone number is dialed.

If the engineering menu is not displayed, then try pressing the call key after entering the combination.

By the way, the owners of devices based on the chipset MediaTek MT6573, MT6577, MT6589 and some others can download the application Engineering menu MTK... As you might guess, the utility will allow you to launch the corresponding menu without entering a numeric code.

If you can't enter the menu

It is quite possible that you will try to enter all the above combinations, but you will not get into the engineering menu. This happens on Android 6 and some other fairly fresh versions of the operating system. Apparently, the engineering menu is locked, or some specific code is required to call it.

Service (they are also engineering, they are also secret) codes are used for quick access to various functions, often even hidden. There are universal codes for Android, and there are those that are available only for certain device models.

Not so long ago I published an article in which I told. To do this, you could use special software or use one of the secret codes. Now I will talk about the most popular of them, thanks to which you can make many system settings.

Popular secret codes for Android smartphones

Why are these codes called "secret"? It's just that they are not needed by most ordinary users, they are not published in the instructions for smartphones. First of all, "secret codes" are intended for engineers and developers to conduct various tests.

To use any of the service codes, you must enter it in the dialer. On tablets you will have to download third party application to make calls - enter in the search Google play request "Dialer" and download the "dialer" you like.

In principle, these are the most basic and universal service (secret) codes for tablets and smartphones on Android, but all manufacturers add support for their own, so if you are interested in codes for a particular device, download the application. It will be discussed below.

Android Service Codes in Secret Codes App

The Secret Codes application will scan the system for engineering codes and display the result in the form of a list. You just have to click on the code of interest and you will be taken to the desired option.

Unfortunately, this method has a drawback: on some devices, the application does not find a single service code, and on some it does not find everything. But on the devices I tested, everything was fine, and the reviews on Google Play are almost all positive.

The engineering menu of Meizu M3 is used to eliminate software failures, as well as to configure the smartphone after repair. Most of the features offered in this menu in practice will not be in demand even by the most advanced users. In this manual, we will tell you how to open the Meizu engineering menu and its main functions.

How to open

To get into the engineering menu (EngeneerMode), type the combination on the keyboard

*#*#3646633#*#*

It is made for Android 4.0, so it looks rather outdated. But, at the same time, no difficulties in understanding the interface should arise.

In total, Meizu M3 and M3 Note have several additional tabs for customization:

  • Telephony;
  • Connectivity;
  • Hardware Testing;
  • Location;
  • Log and Debugging;
  • Others.

Let's take a closer look at them.

Telephony

Here you can test your smartphone modem. There are also several positions for setting up calls. You can see the compatibility of the device with operators. It is better not to go here without knowledge, but in extreme cases there is a button to reset the changes made.

Connectivity

This is where you configure Wi-Fi. You can also see how Bluetooth is configured and correct it if necessary.

Hardware Testing

Here you can find a large number of options for configuring hardware, you can adjust the display, test modules. But, the most popular option is to adjust the volume of the sound in the headphones.

Location

Gives it possible to disable the location function.

Log and Debugging

Others

There are a large number of items here that were not included in the main menu, but may also require settings. You can change fonts, sensor reaction speed, languages ​​and much more.

In conclusion, we note that without special knowledge in the engineering menu, it is better not to change anything, otherwise you can ruin the normal operation of the Meizu smartphone.
