Motorola MMI codes (Man-Machine Interface codes) are sequences of numbers, asterisks (*), and hash signs (#) entered into your phone’s dial pad to quickly access hidden settings, technical information, or advanced hardware testing menus. These codes are invaluable for advanced users, technicians, and anyone looking to troubleshoot device performance issues without navigating through deep settings menus.
While many MMI codes work universally across most Android devices, Motorola also uses specific codes to access its unique Engineering Mode. Below is a breakdown of the most useful MMI codes for Motorola phones, categorized by function.
Disclaimer: Use the codes in the ‘Advanced/Risky’ section with extreme caution. Altering settings in diagnostic menus can affect your phone’s functionality. Always back up your data before performing any reset code.
