What are secret codes on Android and what are they for?
Android secret codes They are combinations of numbers and symbols that, when entered into the smartphone's keypad, allow access to hidden menus, diagnostic functions, technical information, and advanced configuration options. They are little known among most users because they are primarily intended for technicians, developers, and experienced users. Their main advantage is that they allow access to insights and settings that don't appear in the Settings app or the phone's manual.
These codes can be divided into several categories according to their function:
- Information codes: They show data about the hardware, software, battery, IMEI or other technical sections.
- Test and diagnostic codes: They allow you to test WiFi, screen, audio, sensors, camera, GPS or Bluetooth.
- Configuration codes: access internal menus for network, USB, engineer mode or advanced settings.
- Reset and backup codes: They allow you to create backup copies or restore your mobile to its original state.
- Manufacturer-specific codes: Some manufacturers such as Samsung, Motorola, HTC, Realme or OnePlus offer exclusive codes for their devices.
Types of secret codes on Android: USSD and MMI
The android secret codes They are mainly divided into two types according to their operation:
- USSD (Unstructured Supplementary Service Data) codes: They are primarily used to communicate with the operator's network (checking balance, data, network services, etc.). They work without an internet connection. They also allow access to information about the SIM and operator services.
- MMI (Man-Machine Interface) codes: These are specific to the Android operating system itself and/or the device manufacturer. They allow access to internal device functions, test menus, diagnostics, advanced statistics, configuration changes, and other technical tools.
Both types of codes usually begin and/or end with * (asterisk) and # (hash), although the structure may vary depending on the manufacturer and model. Some codes work universally on all Androids, while others are exclusive to certain brands or models.
How do you enter secret codes on Android?
Using these secret codes is very simple:
- Open the phone app on your Android device (the same one you use to call).
- Go to the dialing screen and write the secret code exactly, including all asterisks and hash marks.
- Many codes execute the action automatically when the last symbol is entered. #In others, you may need to press the call button.
Important! Some Manufacturers block certain codes on their devices For security or customization reasons, some codes may not work on your specific phone.
