Entrance To The Service Menu Of The Samsung

Entering the engineering menu on Android (command and program)

Not many people know about the existence of a menu in the Android OS with advanced settings of the device. Engineering menu. And someone knows, but do not know how to enter it and what to do with it.
In this article, we will show you how to enter the engineering menu and some of its capabilities.

You can enter the engineering menu simply by writing a special command (but I must add that this method does not work on all versions of Android and not on all devices)

The command to enter the engineering menu: ## 3646633 ##

Also, on some Android versions, the command # 15963 # and ## 4636 ##

Immediately after entering, the command should disappear and the engineering menu should open. But on some devices, you still need to press the “Call” key

If this method does not work, you can use an alternative!

And it consists in installing the program (which by the way is freely available on Google Play) “Mobileuncle MTK Tools 2.4.0”

This program will open access to the engineering menu (that is, it will work similarly to dialing the combination ## 3646633 ##)

There are a lot of settings! The room for experimentation is huge! Almost EVERYTHING can be debugged and adjusted!

For clarity, let’s briefly analyze the volume level setting of the device:

-We go into the program. Select the “Engineer Mode” section

-Next, select the section. “Engineer Mode (MTK)

-Because we are interested in setting the sound level, select. “Audio”

-And voila, the menu that interests us opens.

Then you only need to “conjure” with the settings and adjust the device for yourself!

Max Vol. One for the entire subsection, as a rule, set to 150 (you can change 0-160. Changes if you select the Media item in the subsection).

If in some submenu, for example, Audio. Normal. Sph general level is not available for regulation, then enter another subsection, for example, Audio. Normal. Media. There will be an opportunity to adjust the overall volume level.

Sub-items:
Sph. Volume levels during telephone conversation,
Mic. Microphone sensitivity levels,
Ring. Ringer volume,
Media. Volume when playing music, movies, in games.

Ring volume levels are set in Audio. Loudspeaker. Ring
Max Vol = 150
Levels: 120 130 145 160 180 200 (more starts wheezing)

Conversation volume levels in the telephone speaker in Audio. Normal. Sph
Max Vol = 150
Levels: 100 120 130 135 140 145 150

Talk volume levels in the microphone in Audio. Normal. Mic
Levels: 100 172 172 172 172 172 172

Media volume levels are set in Audio. Loudspeaker. Media
Max Vol = 150 (it is the same for the entire section)
Levels: 110 130 160 190 210 230 250

All the same can be configured for the Headphone mode, by analogy:

Speaker volume levels are set in Audio. Loudspeaker. Sph
Max Vol = 150 (it is the same for the entire section)
Levels: 80 100 110 120 130 140 150 (more starts wheezing)

Now all volumes are adjusted to adequate ranges.
If you are not satisfied with the volume levels. You can set your own values ​​(the higher the value, the greater the volume when adjusting the volume keys, or the greater the microphone sensitivity)

Most sections can be configured by analogy! Experiment!

Engineering codes for Android :. How to get to Engineering Menu

Entering this menu on Android 4 occurs by entering a special key combination in the dialer, the so-called code, each manufacturer usually has its own combination. So, you need to enter the dialer, and dial:

Samsung. ## 4636 ## or ## 8255 ##

  • Htc. ## 3424 ## or ## 4636 ## or ## 8255 ##
  • Sony. ## 7378423 ##
  • Huawei. ## 2846579 ## or ## 2846579159 ##
  • Mtk. ## 54298 ## or ## 3646633 ##
  • Fly, Philips, Alcatel. ## 3646633 ##
  • How to enter the Android engineering menu

    Few people know, but in Android there is a menu of advanced settings, the so-called “Engineering menu“. And if anyone has heard about this, they may not know how to enter this very menu on Android. It is in this article that I want to tell you how you can get into this section.

    What features are available

    After logging in, a large number of settings will be available (for advanced users). One of the simplest is changing the volume at each level, that is, you can specify what volume will be at the 1st level, which at the 2nd, and so on. This will be useful for phones with standard volume too quiet, making the value higher than usual at the last level. I propose to see everything with an example.

      To do this, after entering the section, select “Engineer Mode”

    • Since we need to change the volume value, select “Audio”
    • Then you will need to experiment with the values, as a rule, the numbers can be set from 0 to 160. Where 0 is absolutely no sound, and 160 is the maximum volume.

    Also, you can make many other changes, in theory, almost the entire functional part, for example, adjust the vibration strength of the phone, the strength of the radio module reception, and much more. If you like to experiment, then there is just something to have fun with, just be careful when changing the values, because you are not in skillful hands, you can not customize the device for yourself, but, on the contrary, only make it more inconvenient to work.
    This is actually the entire manual on how to get into the advanced settings menu on Android 4. Nothing complicated!

    Hello. There is no engineering menu on Samsung devices. But, there is some kind of this menu, which is called “Developer options”. But, these parameters are locked. To unlock them, do this. Go to device settings. Go to the “About device” section. Find the line “Build number” here. Click on this item quickly about 20 times in a row. The inscription “Developer mode unlocked” should appear. After that, “Developer options” will appear in the device settings. But, I will say right away that I DO NOT recommend climbing in these parameters, since you can cause irreparable damage to the device, which will lead to expensive repairs or even damage the device without the possibility of repair.

    Hello. Not all codes work and not on all models. The fact is that some manufacturers simply block this menu, so that inexperienced users do not climb in the system and hardware settings and cannot harm the device. I do NOT recommend that you go to the Engineering menu and change anything there. There are “Developer options”. But he does not recommend climbing here either. These parameters are opened as follows. Go to settings \ about device. Here we are looking for the item “Build number”. It is the assembly NUMBER. Press quickly ten times in a row on this item and you will see the inscription “Developer options unlocked.” Then go back to “Options” and look for “Developer options”. There are some functions of the engineering menu here.

    Hello. I can not help you. I do not have this model of the device at hand and I cannot check everything. Why do you need this? Do you want to make the sound louder? I highly do not recommend doing this, since the sound quality will be just awful, and you yourself will want to return everything back, but only it is not always possible to return everything as it was. In addition, such changes can entail quite serious problems, up to the fact that problems begin with the operation of the device or until the speaker burns out. And this, in turn, will require expensive repairs.

    Good afternoon, tell me how to enter the engineering menu on MTK6582, android 5.0, 4 cores at 1.3 GHz,

    Hello. You were unable to enter the engineering menu? The fact is that the codes do not work on every phone. I don’t know all the codes, so you’ll have to look for the code for your phone yourself. It is possible that the manufacturer has hidden this function altogether and you will not be able to enter the engineering menu.

    Hello. You were unable to enter the engineering menu? The fact is that the codes do not work on every phone. I don’t know all the codes, so you’ll have to look for the code for your phone yourself. It is possible that the manufacturer has hidden this function altogether, and you will not be able to enter the engineering menu. In general, the manufacturer Samsung has long hidden this function from users and the codes simply do not work on phones. This is due to the safety of the device. The fact is that inexperienced users quite often disable individual components of the phone (the speakers burn, the screens stop responding to touch, and so on). These are all consequences of incorrect configuration by inexperienced users. Trust my experience, it’s better not to climb on your own and not try to improve something. The manufacturer has deduced the optimal parameters and you definitely cannot configure anything better.

    Hello. I won’t tell you, because you shouldn’t go into the engineering menu. You will only make things worse with your settings. It’s not for nothing that the manufacturer hides this function from users. Believe my experience, you shouldn’t go into these “jungles”, as you risk turning your device into a brick.

    Hello, what is the code in the engineering settings on the Nomi 451 phone

    Hello. I do not know. I don’t know all the codes. If the standard codes do not fit, then look for yourself. There is a lot of different information on the Internet. But, I will say right away that sometimes manufacturers simply block these codes and you simply cannot open the engineering menu. And I do not recommend going there at all and changing anything there, since the manufacturer already sets the most optimal parameters and you should not change them. The fact is that changing any parameters in the engineering menu with a high probability can lead to a bunch of problems, rather serious.

    And I pressed 300 times the build number

    And the program svsengrunner rocked. Mmi connection error
    Do I just need to set up gps. Help.

    Hello. You won’t set up GPS. Therefore, do not even try to enter the engineering menu. And clicking on the build number (you need to click very quickly) opens only the “Developer options”, in which you also cannot configure the GPS. If navigation does not work for you, then first check if there is a GPS sensor in your device at all. And if there is, but does not work, then specify which one is. And as a last resort, take it to a service center.

    Good evening. Please tell me the code in the engineering menu DOOGEE SHOOT 2.
    When I type the code ## 3646633 ## then nothing happens. Although on DOOGEE X5 MAX PRO in the menu by this code comes. Maybe it’s about ANDROID 7 on SHOOT 2? Thank you in advance!

    How to enter the service menu of a Samsung TV

    Any TV, including those that are not smart TV devices, have a service menu that controls vital settings. In particular, the size of the image horizontally and vertically, brightness correction, and other parameters that can seriously affect the operation of the device. Therefore, if you do not understand how and what to do, it is better to leave this service altogether.

    Not surprisingly, the service menu on Samsung TVs is usually called extended, because it is used if you need to make serious changes in the operation of the TV itself. And to use it, you need to have a special remote control. Over, it is important that it be “native” for the TV, that is, it comes with it. Otherwise, even if you get into the menu, it will be difficult to be there, since the control is not reliable.

    What are the functions of the Samsung TV service menu

    As already mentioned, the average user is not recommended to experiment with the service menu on Smart TVs, including Samsung K series or any other series, even J. It’s not that this is a whim of the developers. On the contrary, users can press the wrong key on the remote control, and all settings will fail, which will lead to a complete loss of the normal performance of expensive equipment.

    But in the hands of the master who entered the service menu of TVs, it can turn a standard Smart TV into almost a home theater. Nevertheless, sometimes such settings can be opened quite by accident, by involuntarily pressing some key combination. If this happens, then you can change:

    The spectrum of the image, for example, by choosing a green palette or red, in connection with which, the picture on the screen will become a country. Few people want to watch TV in this format.

  • Screen image size options. It may turn out that the picture will not occupy the entire screen, but only half of it, moreover, from below, from above or from the side. The picture can break into pixels, and suffer other, unpleasant changes.
  • Naturally, the service menu of a Samsung TV can change the sound parameters, making it so that even at the highest volume, the device is barely audible. Or uses various sound effects, due to which an echo may appear, acoustics will increase, which also does not contribute to a comfortable viewing of content.
  • In addition, once in the service menu of a Samsung TV, you can connect and disconnect various built-in functions.
  • In general, if the user needs to change any automatic settings, then this is done right here.

    How to get into the service menu of Samsung 6 TV

    • Take the remote control and press the following sequence: info. Menu. Mute. Power;
    • Having learned how to enter the service, you need to wait a couple of seconds, since the TV after pressing the specified combination will reboot to display the necessary information;
    • After that, the incoming person must learn to move in such a way that they do not accidentally change the settings. If you need to change something, you must press “Enter” and only then enter the amendments;
    • Go to “Control”, “Cloning” and so on;

    It is important, before finishing the work in the “Hotel Option” section, to mark “OFF” in order to save some functions from failures. And also, since the user has entered the menu, and knows how to enter here at any time, you still need to understand how to exit and not damage the settings. This is done in this way:

    • You can exit by turning off the TV normally;
    • Then go back to MENU-SYSTEM, and see what has changed;
    • If all is well, we entered without any problems and I am satisfied with the settings, which means that you can continue to use the TV with an updated menu.

    On the Samsung Galaxy A5 and Galaxy S6, the main sections of the engineering menu are:

    Telephony (Telephony);

  • Wireless interfaces (Connectivity);
  • Testing Mode (Hardware Testing).

    The main features of the engineering menu on the Samsung Galaxy

    Having figured out how to enter the engineering menu on Samsung, we will consider its main features. A complete Engineering Mode for MTK chips is equipped with a large number of tools with which you can make a complete diagnosis and fine-tune Samsung in many parameters.

    However, many smartphones have a stripped-down version of the technical mode, which slightly reduces its functionality. And in mobile devices based on the Qualcomm processor, through the engineering menu, you can only view information about some modules and perform small tests of the main elements of the phone (display, modem, SIM cards and battery).

    Where to find the engineering menu on Samsung Galaxy

    The main purpose of Engineering Mode is to fully test mobile devices at the final stage of their production. This environment was originally developed for debuggers for smartphones and tablets, but today anyone can use it. The main thing is to know how to open technical mode on Galax.

    You can enter the engineering menu using a special combination (USSD code), which is registered in the dial pad. At the same time, these commands may differ in different phone models:

    • In Samsung J7 and J1, the actual combination is ## 0011 #;
    • For Samsung Galaxy A5, Galaxy S5, Galaxy S6 set ## 8255 ## or ## 197328640 ## is suitable;
    • Samsung Galaxy A3 code ## 9646633 ##
    • For Samsung Galaxy S3. ## 0 ##;
    • In Samsung Galaxy S7 Edge. ## 8255 ## or ## 4636 ##.
    • On other devices from the Galaxy line, you can use the service combinations ## 4636 ##, ## 8255 ## or ## 3646633 ##.

      If you cannot open the engineering menu using the above commands, you can resort to one of the programs developed specifically for this purpose (EngineerMode, Mobileuncle Tools, Shortcut Master, etc.). To start the technical mode, it is enough to install and run one of the utilities. After that, it will automatically enter Engineering Mode.

      All applications for opening the engineering menu work only with MTK processors (MT6573, MT6577, MT6589, etc.) and with some Exyon chips. For phones equipped with a Qualcomm CPU (e.G. Samsung Galaxy A5), this software will be useless.

      How to work with the engineering menu of Samsung Galaxy

      Many devices running Android OS are additionally equipped with a special environment. The engineering menu. With its help, the user has the opportunity to test all sensors and modules of the mobile device, as well as adjust certain parameters of the gadget for himself for more comfortable use. In Samsung phones, Engineering Mode is hidden in the system by default. And in different models, the entrance to it is performed differently. And the functionality of this area may also differ. Let’s take a look at how to enter the engineering menu on Samsung Galaxy A5, Galaxy S6, J3 and other smartphones from the Galaxy line.

      In the Telephony tab, the user can:

      • Activate / deactivate an answering machine for incoming calls;
      • Mark frequencies for GSM telephone communication;
      • Choose the communication standards on which the Galaxy A5 will work (2G, 3G, LTE or their combinations);
      • Configure access to the Internet, etc.

      The Connectivity section is intended for diagnostics and configuration of Wi-Fi, Bluetooth and FM wireless modules. It is not recommended to change anything here, as this can lead to the failure of the smartphone.

      The most popular engineering menu tab is Hardware Testing. This is where you can test the health of the processor, battery, speakers, camera, display and GPS module. This area allows you to make a complete diagnosis of Samsung at the time of purchase and identify possible product malfunctions.

      An example of using the engineering menu

      One of the most effective tools available in Engineering Mode is BandMode. Here you can turn off unused GSM frequencies, which will reduce the load on the battery and increase its autonomy. On the Galaxy S6, this is done as follows:

      Enter the engineering menu and open the Telephony section.

    • Select the BandMode tab.
    • Mobile devices supplied to the European market have two pairs of frequencies that they will scan. 900/1800 and 850/1900 MHz. However, only the first pair is used. Therefore, leave the checkboxes at 900 and 1800 MHz, and uncheck the rest of the values.
    • Confirm your changes by pressing SET.
