When a smartphone is manufactured, it has to undergo several tests and analyses. But testing every feature would be time-consuming. Therefore, secret codes for Android were introduced. These codes are not hidden, but they are lesser-known to the users. Unstructured Supplementary Service Data or USSD is a protocol that generates a query upon our request to the service providers and provides us with the desired information. In this article, we have compiled a comprehensive USSD codes list & tricks for the most common mobile phone manufacturers such as Samsung, Xiaomi, Realme and many more!
90+ Hidden Android Secret Codes
Apart from common secret codes, some codes are used by specific manufacturers on their devices exclusively.
- USSD codes provide various details about the device and also perform specific tasks. USSD codes can be used in all cellular networks and do not require connecting to the Internet.
- Man-Machine Interface i.e. MMI codes are used to provide information such as IMEI number, hidden menu, and such.
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.
