What combination should I enter to... Service (secret) codes for Android smartphones
The term “secret codes for Android” refers to such combinations of characters that were originally intended for testing devices on which this operating system is installed.
With their help, developers test phones and tablets before sending them for sale. And their total number reaches several dozen.
Entering a certain sequence allows you to obtain data or perform actions that are inaccessible to ordinary users. For example, find out the IMEI identifier, reset the system to factory settings, or check the operation of individual modules.
Features of “secret” ciphers
Many users who are faced with the need to use such commands may wonder about the reason for their secrecy.
First of all, the combination of symbols and numbers got this name because most owners of gadgets running this OS do not need them. And there is no mention of these commands in the instructions.
To use any of them, you need to enter the Phone application in the dialer (green or blue handset on the main screen).
Tablets without a 3G module do not have this option by default. And in order to run the codes, the user must download a special application, finding it in PlayMarket by searching for “Dialer”.
Combinations for any gadget on Android OS
Information sequences allow you to obtain data about various characteristics of the device and its individual elements:
- *#06# – about the IMEI number;
- *#*#4636#*#* – about the battery and Wi-Fi network;
- *#*#44336#*#* – about the firmware, including the CSC number and build date;
- *#*#232338#*#* – about the wireless network address;
- *#34971539# – about the gadget’s cameras;
- *#*#1234#*#* (although *#2222# works much more often) – about the firmware.
By entering *#*#1111#*#* you can get the software version information on the screen.
Introduction *#*#2222#*#* shows information about the board of the smartphone or tablet.
Information about the sensor version will be shown by the code *#*#2663#*#*, about RAM - *#*#3264#*#*, and Bluetooth address data - *#*#232337#*#*.
Commands for verification and tests
There is a separate group for testing the device:
- checking the Google Talk service is provided by the sequence *#*#8255#*#*;
- to check the display operation – *#*#0*#*#*;
- for testing various parts (from camera to microphone) – *#0*#;
- for the audio test - two at once: *#*#0673#*#* and *#*#0289#*#*.
You can check the operation of the backlight and vibration by entering the combination *#*#0842#*#*.
The Wi-Fi wireless network is tested using the command *#*#232339#*#* and an additional *#*#526#*#*.
The GPS sensor is tested by sending the commands *#*#1472365#*#* (for a normal test) or *#*#1575#*#*.
The Bluetooth network is checked via *#*#232331#*#*.
Several more useful commands allow you to test the performance of the screen (*#*#2664#*#*), motion detectors (*#*#0588#*#*) and the GSM module (*#*#7262626#*#*). And entering *#197328640# provides a transition to the service mode.
Dangerous combinations
There are several options, by introducing which you can make serious changes to the system without the ability to return to its original state. These include, for example, *#*#7780#*#* and *2767*3855#.
The first ensures that all settings are reset and user-installed applications are removed, the second command leads to a complete reinstallation of the system.
The combination *#*#7594#*#* allows you to get rid of the shutdown menu - when you press the corresponding button, the tablet or smartphone will automatically turn off without asking the user anything.
Selecting the code *#*#8351#*#* is needed to enable voice dialing registration, and *#*#8350#*#* is needed to disable this mode. The sequence #*5376# is used to erase messages, and several combinations for Android like #*3876#, #*3851# and #*2562# reboot the gadget.
Special codes for products of individual manufacturers
There are several combinations that are suitable only for certain models or brands of gadgets. They can be summarized in a small table.
Besides these, there are other commands. The special Secret Codes application from PlayMarket will help you find them. With its help, you can even detect those that are not on the list.
You should know: Not all of the sequences, even universal ones, will work on every smartphone. The use of a secret combination may be limited by root rights or a self-reinstalled operating system taken not from the official website, but from third-party sources.
Results
Most of them should be used very carefully. Especially those that not only provide some information, but also make changes to the operating system or firmware. When used correctly, engineering combinations can be quite useful.
The versatility of the computer allows users to perform certain actions many times faster. Almost everyone knows that in the operating system there are so-called “hot keys” or simply shortcuts. They make it possible to interact with the device many times faster, while significantly saving the user’s time and effort. However, not everyone knows the reliable true number of possible keyboard shortcuts, which only very experienced users know about.
This functionality was developed and introduced by specialists to simplify life and work with a computer as much as possible. After all, by making just a few movements with your fingers, you can instantly skip the long process of searching and launching a particular program. This, in turn, increases the user's potential, allowing him to perform various tasks on the computer many times faster.
The most useful and common combinations
It is difficult to say which combinations are more popular, in demand and useful, since each of them in itself contains enormous potential. But still, from the entire list of possible combinations, we can single out that “basis” that even a novice user should be familiar with.
“Copy”, “Cut” “Paste” - basics for beginners
Copying text information, a file, or an entire folder to the clipboard with further movement are functions that are difficult to do without. Carrying out such actions using a pointing device (mouse), the user will have to spend an impressive amount of time on this. However, using hotkey combinations can save a lot of time. To learn how to use such a combination on the keyboard, you need to:
Reference! Copying or cutting any element existing on the PC leads to its placement in a special “intermediate” storage of general data - the clipboard.
Select all contents and cancel actions with a few keys
To take advantage of these features:
Reference! These hotkeys can be used in various applications such as Word, Excel and others.
Combinations for working with files that are open in applications
For those who spend a lot of time working in Word, it will be useful to learn about those combinations that will reduce the time spent using this program:
Buttons for quickly working with dialog boxes
To quickly “move” between open programs and applications, instantly close them and scroll through them in one second, you need to know special combinations.
- To “jump” between running programs, the user must simultaneously press “Alt” + “Tab”.
- To scroll backwards, press Alt+Shift+Tab.
- The “Ctrl” + “Tab” combination will allow you to instantly move from one document to another in one application. This is also useful when changing tabs in some programs.
- To quickly close a running application, use the simultaneous pressing of “Alt” + “F4”.
- “Ctrl” + “F4” pressed together will not close the entire application, but only one document or tab.
- To quickly “hide” displayed windows, you can combine “Win” + “D”.
Application in practice of so-called “modifier keys”
There are certain buttons on every PC keyboard that are called “modifiers.” They got their name from the fact that they allow you to perform a large number of actions when you click on them. You can also combine them, both with each other and between simple keyboard buttons. This makes it possible to increase the number of commands executed by just one key. The list includes:
- "Ctrl";
- "Shift";
- "Alt"
- "Win."
Keyboard combinations when surfing the Internet through Internet Explorer
Like other existing web browsers, Internet Explorer can use a variety of hotkeys that allow you to instantly save, add and copy entire sites. The main hotkeys for this application are:
- “Ctrl” + “D”, which allow you to instantly add a site to your “favorites” list.
To add a site to the list of favorites, press the keys “Ctrl” + “D”
- To ensure quick closing of one tab, press "Ctrl"+"W".
- “Ctrl” + “T” makes it possible to open another additional tab.
- Pressing "F5" will refresh the web page.
- Using “Ctrl” + “Tab” you can quickly switch between all available tabs.
- And the combined press “Ctrl” + “J” will display a list of available downloads.
Useful combinations for quickly working in Explorer
There are the following possible combinations to simplify the use of Explorer:
Table of useful key combinations.
This table contains some useful combinations that will significantly speed up the process of user interaction with the PC.
| Combination | Function |
|---|---|
| "Alt+Enter" | Displaying properties |
| "F2" | Name change |
| "Ctrl+NumpadPlus" | Automatically select the width of existing columns of a specific list |
| "Enter" | Completely replaces double-clicking with a controller (mouse) |
| "Delete" | Removal |
| "Shift+Delete" | Complete liquidation without moving to the Trash |
| "F5" | Refresh the displayed window |
| "Backspace" | Move up a level in the window |
| "F4" | Go to address bar |
Entering "special characters"
To put the so-called “hiding” or simply “special characters” into practice, you need to use the following combinations: hold down the useful “Alt” key and use any of the “Numpad” numbers.
The user can find the combinations themselves in this table in the screenshot.
How to change combinations of an existing keyboard layout
In order to do this, you will need:
Lock the entire keyboard with a key combination
Unfortunately, it is almost impossible to perform this action on a personal computer without using third-party software or lengthy settings in the operating system itself. But it’s easy to do on a laptop, just press “Win” + “L”.
But on different models, these keys may be intended for other actions, so you can use the “NumLock” + “Fn” combination.
If these combinations do not help, you can use the following:
- "Fn" + "F6".
- "Fn" + "F11".
Reference! It all depends on the manufacturer and the specific model of the device itself. The user is also recommended to inspect the keyboard for the presence of special icons that symbolize locking.

Service (aka engineering, aka 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 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 a third-party application to make calls - enter the query “Dialer” in the Google Play search and download the “dialer” you like.

- ##8626337# - VOCODER (for HTC)
- ##33284# - technical data of network status (for HTC)
- ##7738# - protocol revision (for HTC)
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 specific device, download the application. It will be discussed below.
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.
8 combinations on your phone will help you find out if you are being wiretapped. There has been so much talk lately about wiretapping carried out by secret service workers, be it an ordinary worker or a high-ranking official. But no one fully knows how deep security officials can go to eavesdrop on mobile devices.
Perhaps this is just the fruit of the sick imagination of the media and spy films, which never cease to be popular all over the world, and there are no auditions at all.
Below are 8 combinations on your phone to help you figure it out. These combinations are not known to most phone users; not even every operator knows about them.
1. *#43#
Information about call waiting on the phone is displayed.
2.*777# (code for Ukraine)
Find out your current balance and display the mobile operator menu depending on which one you are currently using.
3. *#06#
This code allows you to obtain unique IMEI data for any phone.
4. *#21#
Using this combination, you can find out whether someone else besides you is receiving your calls, SMS or other data. All this can be done by finding out whether forwarding is enabled on your smartphone.
5. *#33#
Data is displayed about which services your phone supports and which of them are currently emanating from the device. This can be calls, SMS and much more.
6. *#62#
Shows the number to which your calls and data are forwarded, if available.
7. ##002#
This code is used to disable call forwarding so that only the owner of the device, that is, you, can receive calls.
8. *#30#
Provides the necessary information to determine the number of incoming calls.
These simple combinations can protect you from simple ways to infiltrate your phone from the outside. However, against more complex methods, if they exist, they are unlikely to be reliable protection.
Secret codes for iPhone: pushing the boundaries of what's possible
Did you know that iPhones have secret codes? With their help, you can see a lot: from signal strength to call forwarding status. So, let's see what we can do here:
1. Hide your phone number
If you need to hide your phone number, just perform this simple manipulation, and you will already be calling as “Unknown”.
Sticks and dashes are today a visual representation of signal strength that lacks precision. Enable “Field Test Mode” and dial the number as above. Then, after the call starts, hold down the power button. Once the screen turns off, press the center button and wait until you return to the home screen. You will be interested in the number in the upper left corner of the iPhone, which will replace the sticks indicating signal strength.
3. Find out your unique phone code
It is in the settings, but in order not to search for a long time, just dial the following combination of numbers.
4. Determine where your messages go
Any SMS first gets to the SMS center using a special identification number. To find it out, dial *#5005*7672# and call! Voila!
5. Call barring and call waiting mode
Call barring mode allows you to block incoming and outgoing calls, and the “waiting” mode allows you to hold an ongoing or incoming call. If you have paid for both of these services, you can use the above codes. Share this useful information with your family and friends!
