Also known as service codes, they are sequences of numbers and special characters that allow access to advanced features not generally available through the standard user interface.
The hidden codes in Xiaomi mobiles are sequences of numbers and special characters that allow access to advanced features and settings not typically available through the user interface nor in the system configuration.
This function varies by model, but usually some codes display detailed information about the device, such as IMEI number, firmware version, OS version, battery information, network MAC address, etc.
They are especially useful for carrying out specific actions without having to perform them manually. As a general rule, to find out information about a technical detail of the mobile we usually enter the system settings in Android and device information.
But with the hidden codes we will be able to access the same information in a much faster and easier way, since they are shortcuts that make the task easier for us. You just have to use the phone keyboard application to dial each of these codes.
