MMI codes for Android devices are special number sequences that unlock hidden features and settings on smartphones. These codes work through the phone’s dialer app and give users direct access to system information, diagnostic tools, and advanced settings that aren’t normally visible in regular menus.
Android users can access important device information like IMEI numbers, perform hardware tests, and check network settings by typing specific MMI codes into their phone’s dialer. These secret codes use asterisks (*) and hash symbols (#) in specific patterns to activate different functions. Some codes work on all Android phones, while others only work on certain brands like Samsung or OnePlus.
Most Android users don’t know these codes exist, but they can be useful for troubleshooting problems or checking device details. The codes range from simple information displays to more advanced diagnostic tools that tech-savvy users might find helpful. Understanding which codes work on your specific device can save time when you need quick access to system information.
