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.

Introduction a certain sequence allows you to obtain data or perform actions that are not available to ordinary users.

Contents:

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, combinations of symbols and numbers received this name due to the fact that most owners 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 special application, having found it in the query “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.

When entering *#*#1111#*#* You can get information about the software version on the screen.

Introduction *#*#2222#*#* shows board information.

Information about the sensor version will be shown by the code *#*#2663#*#* , about RAM – *#*#3264#*#* , and the Bluetooth address data is *#*#232337#*#*.

Commands for verification and tests

There is a separate group for testing the device:

  • Google Talk service check ensures consistency *#*#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#*#* .

Tested using the command *#*#232339#*#* and additional *#*#526#*#* .

The check is performed by sending the commands *#*#1472365#*#* (for regular test) or *#*#1575#*#* .

The Bluetooth network is checked via *#*#232331#*#* .

Several Yet useful commands allow you to test the performance of the screen ( *#*#2664#*#* ), motion detectors ( *#*#0588#*#* ) and GSM module ( *#*#7262626#*#* ).

A input *#197328640# provides transition to 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.

Combination *#*#7594#*#* allows you to get rid of the shutdown menu - when you press the corresponding button, or will automatically turn off without asking the user anything.

Code selection *#*#8351#*#* needed to enable registration voice dialing, A *#*#8350#*#* – to turn off this mode.

Subsequence #*5376# used to erase messages, and several combinations for Android type #*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.

Table 1. codes for certain models mobile devices on Android OS.
brand, modelTeamAction
Sony**05***# unlocking PUK code
LG, G33845#*855# entering the service menu
Samsung, Galaxy S4*#0011# go to menu
HTC##3424#

##33284#

starting the diagnostic process

network status information
Motorola*#*#786#*#*

*#*#2486#*#*

reset all settings

go to built-in menu

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 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 operating system or firmware.

When used correctly they can be quite useful.

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.

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 doesn’t find everything. But on the devices I tested everything was fine, and the reviews were Google Play Almost all are positive.

Crazy 5110
Send a message from some points (...........) and the phone will go crazy if you try to scroll through the received message. I'm not sure that this will work in phones with software versions 4.59. and 4.53..

Your phone number on the screen
1.ї Enter menu 3-7 setting call costs.
2.ї Enable the cost limit 3-7-1.ї A PIN2 code will be requested.
3.ї Enter your phone number into the limit.
For example, my phone is 095 11111111
enter the limit 11111111
4.ї Go to menu 3-7-2 Show cost.ї A PIN2 code will be requested.
5.ї Select Currency.
6.ї Enter cost: 1
7.ї Enter the name of the currency as 095

Now your number 019 1111111 will be shown on the 4th line of the screen
Free call You must have Net Monitor mode on your phone.
This mode was removed in some versions, such as v4.73 and v5.04.

1 Enable NetMonitor in Nokia 51xx/61xx
2 Use test number 497
3 You now have the opportunity to chat for about 90 seconds.

There is no confirmation that this trick still works. Service Provider Lock The Service provider (SP) lock mode is used to bind the phone to a specific SiM card. Moreover, if you insert a SIM card from another operator, the phone will refuse to work, but another card from the same operator will work.
All Nokia phones (2110 and above) have four different binding modes that can be used to link cards with four different operators. But most phones only have one activated. (lock 1)
The main code used in Nokia phones:
#pw+(master code)+Y #ї
This code is used to verify, activate and unbind Sim card(SP-lock).
Use the * key to type p, + and w characters.
"Y" can be 1,2,3 or 4 - depending on what type of binding you choose.

#pw+1234567890+1 # for Provider-Lock status
#pw+1234567890+2 # for Network-Lock status
#pw+1234567890+3 # for Provider(???)-Lock status
#pw+1234567890+4 # for SimCard-Lock status
(master code) a ten-digit number based on IMEI number phone.
To unbind by type 1, enter the following code:
#pw+(master code)+1 #ї
If you just want to check your phone, use any ten-digit number instead of the master code, for example 1234567890
Note: Be careful with this code, as the code can only be entered 3 times, then something may happen to your phone

There is also another option.
If the phone is encoded with an SP (service provider) code that is unknown, then try the following:
& #61623; first, the PIN code must be enabled;
& #61623; turn on the phone;
& #61623; When asked for a PIN code, press C, then the up or down arrow;
& #61623; press C and hold until the display clears;
& #61623; now enter the command to change the PIN code, but without changing it: **04 *PIN *PIN *PIN #
This operation must be repeated every time the device is turned on.
Security code Information in IMEI (International Mobile Equipment Identity) contains:

XXXXXX XX XXXXXX X
TAC FAC SNR SP

TAC = Type Approval Code (first 2 digits = country code).
FAC = Final Assembly Code (For Nokia FAC=10).
SNR = Serial Number.
SP = Spare (always SP=0).
