Android smartphones are packed with hidden features and diagnostic tools that are not usually accessible through regular settings. These tools are often embedded in the system and can be accessed using what are known as Android secret codes. These codes, also called dialer codes or USSD codes, allow users to uncover hidden menus, test device components, retrieve hardware information, and much more.
If you want to explore deeper aspects of your phone or troubleshoot certain issues, knowing these secret codes can be a game-changer. In this article, we’ll dive into what Android secret codes are, how to use them, their features, pros and cons, alternatives, and our final verdict.
What are the Android Secret Codes?
Android secret codes are special numeric or alphanumeric codes that you can type into your phone’s dialer to access hidden system information and functions. These codes are mainly used by developers, technicians, and advanced users to test hardware, analyze software versions, reset systems, or pull detailed logs.
Examples of secret codes include:
-
*#06#— Displays the device’s IMEI number -
*#0*#— Opens the hardware test menu (on some devices) -
*#*#4636#*#*— Shows detailed phone, battery, and usage statistics
These codes vary depending on the device brand (Samsung, Xiaomi, Oppo, etc.) and Android version, and may not work on all phones due to manufacturer restrictions.
How Android Secret Codes Work
When you enter a secret code in your phone’s dialer, the system interprets it as a command to open a hidden function, menu, or service mode. These codes bypass the normal user interface and access areas of the Android operating system that are not typically visible.
Here’s how to use them:
-
Open the Phone app.
-
Enter the code exactly as shown (e.g.,
*#06#). -
The feature or menu will automatically open (no need to press the call button).
Note: Not all codes work on all phones. Some may require root access, while others may be disabled by the manufacturer for security reasons.
