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 check phones and tablets before they are sent for sale. And their total number reaches several tens.

The introduction of a certain sequence allows you to get data or perform actions that are not available ordinary users. For example, find out the IMEI ID, reset the system to factory settings, or check the operation individual modules.

Features of "secret" ciphers

Many users who are faced with the need to use such commands may wonder why they are secret.

First of all, combinations of symbols and numbers received such a name due to the fact that most owners of gadgets on 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 feature by default. And in order to run the codes, the user must download special application, finding it in PlayMarket for the query "Dialer".

Combinations for any Android gadget

Information sequences allow you to obtain data about different characteristics device and its individual elements:

• *#06# - about the IMEI number;
• *#*#4636#*#* - about the battery and the 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 information about the software version on the screen.

The introduction *#*#2222#*#* shows data about the board of a 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

To test the device, there is a group:

• verification Google services Talk provides the sequence *#*#8255#*#*;
• to check the operation of the display - *#*#0*#*#*;
• for testing different 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 additional *#*#526#*#*.

Check GPS sensor are performed by sending the commands *#*#1472365#*#* (for a normal 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 the GSM module (*#*#7262626#*#*). And entering * # 197328640 # provides a transition to the service mode.

Dangerous Combinations

There are several options, by entering which, you can make serious changes to the system without the ability to return to the initial state. These include, for example, *#*#7780#*#* and *2767*3855#.

The first one provides a reset of all settings and removal of applications installed by the user, 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#*#* to disable this mode. The sequence #*5376# is used to delete messages, and several combinations for Android like #*3876#, #*3851# and #*2562# restart the gadget.

Special codes for products of individual manufacturers

There are several combinations that are only suitable for certain models or brands of gadgets. They can be summarized in a small table.

In addition to these, there are other commands. A special Secret Codes application from PlayMarket will help you find them. With it, you can even find those that are not on the list.

many owners mobile phones heard the abbreviation IMEI, but not everyone understands what exactly it means given code and for what purposes it can be used. IMEI is the standard serial number of a mobile device, its international identifier, which is affixed by the manufacturer for each individual device. This code is unique and transmitted to the network mobile operator when connecting the device. The most common reason for checking the IMEI is the theft of the gadget. Those. if in stolen cellular telephone a new SIM card will be supplied, law enforcement will be able to trace the owner of this card and seize the gadget. About all features and applications serial number and IMEI will be described in the article.

What is the IMEI of the phone for?

The standard IMEI contains a 15-digit code. Manufacturers mobile devices never release two gadgets with the same IMEI serial numbers. This character combination was originally programmed in software mobile device, the so-called "firmware", regardless of what model and brand of phone you have (Samsung, Nokia, HTC, Acer, etc.).

This code is for unique identification cellular device in GSM networks. In other words, if the user turns on the device without a SIM card, it will appear in the operator's network. IMEI code decoding

The IMEI combination is decrypted as follows:

• the first 6 characters indicate in the international classifier Type Approval Code (TAC) - an approved type encoding that is assigned to a specific phone model. In this case, the first 2 characters are the code of the country where the gadget was released;
• the next 2 characters are the identifier of the country code that made the final assembly of the device. It is called the Final Assembly Code (FAC);
• the next 6 characters are directly the unique serial number of the phone, which is denoted by the abbreviation SNR (Serial Number);
• the final 1 digit is a reserve number called SP (Spare) and is almost always 0.

Scope of IMEI

1. Checking the IMEI code is the most efficient and easy way obtaining information about a mobile gadget before you pay for its purchase at a point of sale. Just one simple combination will allow you to instantly check the compliance of the “wired” IMEI with the number that is printed on the device case.
2. Also, checking the code allows you to protect yourself from the risk of buying a stolen phone. Each user who has become a victim of theft or loss of his gadget can leave the serial number of the lost device in the IMEI database.
3. This serial number will also allow you to find a lost or stolen phone. To do this, you need to add a combination of the missing gadget to the IMEI database in order to increase the chances of finding the lost device.
4. By blocking access to the device, which can be carried out by the operator mobile network after confirming the ownership of the phone, the user will be able to restrict intruders' access to the network in different coverage regions.
5. Finally, the presence of an IMEI code indicates the integrity of the manufacturer, the build quality and the security guarantee for each client.

How to find out your IMEI

It's not hard to check the code. The vast majority of mobile gadgets, regardless of model and type operating system, respond to a simple combination. Usually it is enough to identify the serial number, which works on both old and new gadgets.

Not so long ago, I published an article in which I said,. 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 carry out many system settings.

Popular secret codes for Android smartphones

Android service codes in the Secret Codes app

The Secret Codes app will scan the system for engineering codes and list the result. You just need to click on the code of interest and you will go to the desired option.

Unfortunately, this method has a disadvantage: 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 in Google Play almost all are positive.
