Frequently Asked Questions
We've put together a list of the best secret codes for Android phones and tablets to help you access and unlock non-obvious features of Android. Some of them will work for all Androids, but other codes are device-specific.


How to Use Android Secret Codes
All phones that run Android have a built-in protocol called USSD (Unstructured Supplementary Service Data), which allows users to quickly access features on their phone regardless of the manufacturer.

To use Android secret codes, go to the Phone app, open the dial pad, and enter a code. You don't need to tap Call. If your phone supports the code, it should execute automatically.
