Secret codes for Android smartphones. Special hidden codes for Android smartphones. Android service codes in the Secret Codes application

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

You can enter the engineering menu simply by entering a special command (but we must add that this method doesn't work for everyone Android versions and not on all devices)

Command to enter the engineering menu: *#*#3646633#*#*

Also on some versions of Android the command may work *#15963#* And*#*#4636#*#*

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

If this method does not have any effect, you can use an alternative!

And it consists of 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 a combination*#*#3646633#*#*)

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

For clarity, let’s briefly look at setting the device’s volume level:

Go to the program ---> select the "Engineer Mode" section

Because We are interested in adjusting the sound level, select ---> "Audio"

And voila, the menu we are interested in opens.

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

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

Sub-items:
Sph - volume levels during telephone conversations,
Mic - microphone sensitivity levels,
Ring - ringer volume,
Media - volume when playing music, movies, and games.

Ring volume levels are set in Audio - LoudSpeaker - Ring
Max Vol = 150
Levels: 120 130 145 160 180 200 (starts to wheeze more)

Phone speaker conversation volume levels in Audio - Normal - Sph
Max Vol = 150
Levels: 100 120 130 135 140 145 150

Microphone conversation volume levels in Audio - Normal - Mic
Levels: 100 172 172 172 172 172 172

Media volume levels are set in Audio - LoudSpeaker - Media

Levels: 110 130 160 190 210 230 250

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

Speakerphone 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 wheezing starts)

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

By analogy, you can configure most sections! Experiment!

Some users, faced with difficulties in completing a particular game, use special cheat codes that greatly simplify the gameplay. However, if the introduction on a computer does not raise any questions, then how to enter cheat codes on Android if there is simply no keyboard in the game on a smartphone or tablet?

“Cheat” (from the English cheat) is translated as “cheating,” but how fraudulent can the use of cheat codes be called? In most video games or PC games, these codes are initially built in by the developer and represent a specific set of characters. This is done in order to test the software at the development stage. For example, using a cheat code, the developer will not go through all the levels of the game to test the last one, but will immediately get to the desired level.

Another possibility that the developers did not foresee is a change in running game memory contents, as well as data storing the entire amount of information regarding the player’s progress, or save files (configuration files). This scheme is much more complicated, but it makes it possible to transform a game variable or any of its parameters. The use of such cheat codes requires the use special programs, responsible for a specific memory address containing the necessary information about the character.

As a result, the player has the opportunity to use cheats on Android, for example, for weapons, “a lot of money”, “immortality” and others, giving the user the advantage of making free in-game purchases, unlocking new locations and levels, instantly leveling up the hero, etc.

How to enter a cheat code on Android

Well, if we have figured out cheat codes in general terms, then the main question of our topic remains open for now. If we use the keyboard to enter cheats, say, on a PC, then how to do it on Android devices?

Using a standard keyboard

In fact, to enter codes you can use standard keyboard, making it possible to call it directly in the game. To do this we need a document editor program Smart Office 2(you can either in Google Play), which you need to install on your device.

Now we open the game loaded into the device’s memory (in the screenshot “”, but it could be any other game), then minimize it by swiping and pressing the “ button home»:

Then we launch Smart Office 2, click " new document "and select any document format, for example, DOC. Now press the button at the bottom of the display Edit"(on tablets, for this action, press the button located at the top " Keyboard»):

After these steps, we will have a keyboard that will not retract after we close the application. All we have to do is select our game through the task manager. This can be done by long pressing the “ Home"or, as in the screenshot (smartphone Huawei Honor 5A), the rightmost button in the form of a square on the right side of the display (see above). We tap on the game and when it opens, we will see that the keyboard remains in place:

Using third-party software (GameKeyboard+)

It is possible that the method described above is not relevant for your device, in which case you can use the “GameKeyboard+” application to enter cheat codes. This is a special keyboard designed for modern Android devices for comfortable gaming control.

To use this opportunity to enter cheat codes, download and install GameKeyboard+ on your Android (the application is available for a fee). Having launched the program, we see home page and begin to act according to the presented guidelines.

The first step (click on the field step 1) select the keyboard - put a tick in the line “ Game Keyboard", a window will open in which you need to confirm the selected action (button " Yes«):

The second step ( step 2) select the input method. After we press the line with the third step ( step 3) a gamepad and other control tools will appear. Some games will require you to configure them (for example, to open the inventory in Undertale). To do this, press the button “ Usage Mode" and in the window that pops up, put a tick in the line " Edit Mode«:

To remove unnecessary buttons, click on each of them in turn, and then in the window that opens, click the “ Remove". To complete the action, tap on the line “ tap Top-Right screen corner/Vol-Up…" and in the menu that opens " Select Action"Press the button " Cancel"(in the screenshot the third fragment):

If there is a need to call only the keyboard (for example, to enter, etc.), then for some device models it is enough after the first and second steps (see screenshot 1 and 2) to press the button " Usage Mode" and check the box " Show Qwerty"(see the first fragment of the screenshot below).

After the gamepad appears, we need to press the “ Settings” (settings) and check the boxes:

• 8-way D-Pad(8-way D-Pad).
• Instead of the gamepad, show cl-tour by default.
• [Vol. Up] (to call the keyboard with the “volume” button (to increase).
• « Don't block"(for the convenience of moving the mouse pointer. If lags appear on your device, this action can be canceled).
• « Show warning", and " Use joystick."(here checkboxes can be set by default).

Once the setup is complete, exit the Game Keyboard (the " Exit") and launch the game. If necessary, call up the keyboard to enter cheats, use the “Volume +” button:

If you need to call the gamepad, click on its image in the lower left corner of the keyboard, this action will open the on-screen cross (i.e., cursor keys), as well as the left and right mouse buttons (" buttons) A" And " IN"). To return to keyboard mode, use the " X" Pressing the back button on your smartphone will completely remove the keyboard (or gamepad).

In the settings, you can check the box to make the keyboard translucent, change the configuration and size of the gamepad.

*Note: you need to enter cheat codes slowly, strictly observing the correct case of letters, spaces and symbols.

We hope that the presented hack tools helped you in solving the question of how to enter cheats on Android. We remind you that we will be grateful if someone shares with our readers their own method, different from those described. Good luck!

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

Not 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”? They are simply 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 need to enter it in the dialer. On tablets you will have to download third party application to make calls - enter in Google search Play the request “Dialer” and download the “dialer” you like.

Android service codes in the Secret Codes application

The Secret Codes application will scan the system for engineering codes and display the result in the form of a list. You just need to click on the code of interest and you will go 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 were almost all positive.

operating system Android initially focused on mobile devices. Therefore, there are special engineering or, as they are also called, service codes for Android, intended for service center engineers and advanced users.
Using service codes, you can find out system information about the device and operating system, reassign keys, reset settings and many other interesting things. But there is one But!
