When a smartphone is made, it must go through a series of testing and analysis. However, testing each feature would take a long time. As a result, Android secret codes were introduced. These codes aren't hidden, but they aren't well-known by the general public. Unstructured Supplementary Service Data, or USSD, is a protocol that sends a query to service providers in response to our request and returns the desired information. We've prepared a comprehensive collection of USSD codes and methods for the most popular mobile phone brands, including Samsung, Xiaomi, Realme, and many others, in this page!
90+ Android Hidden Secret Codes
Aside from common secret codes, several manufacturers utilize their own codes solely on their gadgets.
- USSD codes can be used to get information about a device as well as execute specified operations. USSD codes work on all cellphone networks and don't require an Internet connection.
- MMI codes, or Man-Machine Interface, are used to provide information such as the IMEI number, hidden menu, and so on.
Note: You must be careful because some of these codes might cause data loss and/or perform a factory reset of your Android phone. In addition, some of these may or may not work anymore.
