The Android operating system is well known for its hidden features and easter eggs. One such area is using custom dialer codes to access various hidden apps and settings. Some of these codes are universal, which means you’ll get the desired output on any Android device, irrespective of them being a great flagship or a cheap budget phone. However, custom OEM skins (e.g. One UI by Samsung and MIUI by Xiaomi) and carrier-customized models often come with their own set of hidden codes.
Below you can find a bunch of generic as well as device-specific Android hidden codes. Give them a try and discover some of the handiest secret functionalities of your phone. If you don’t see your device listed or you want to submit a new code, send a message to Skanda Hazarika (SkandaH on the forums) with all the relevant details.

Structure of the Android hidden codes
The so-called hidden codes are basically part of the Man Machine Interface (MMI) schema. These are a bit different from the Unstructured Supplementary Service Data (USSD) codes, although both of them start with an asterisk (*) followed by digits that comprise of commands or data. Groups of digits may be separated by additional asterisks. The message is terminated with a hash symbol (#), but custom MMI codes may end with an asterisk as well.
While USSD codes are used to communicate with the mobile network operator’s servers for menu-based information services, mobile-money services, and location-based content services, the MMI Supplementary Service codes work completely offline.
Just like USSD, you have to dial the “hidden” codes on the stock dialer app to invoke the corresponding action.
