Like any sophisticated system, Android includes developer-created backdoors for troubleshooting and testing. These hidden features cannot be accessed through the usual interface but are available via specialized dialer codes.

⚠ Caution Before Using Secret Codes

Some of these codes can reset your device, delete data, or modify system settings. If you encounter a setting you don’t understand, do not proceed to avoid unintended consequences.

How to Use Android Secret Codes

Android devices support USSD (Unstructured Supplementary Service Data), allowing quick access to specific functions. To use a secret code:

Open the Phone app.
Navigate to the dial pad.
Enter your chosen code from the list.
If your device supports it, the command will execute automatically without needing to press ‘Call’.
