16 Best Xiaomi Secret Codes You Must Know

In this list, we gather some of the most useful Xiaomi secret codes from MIUI operating system. Test phone components, format the system or learn useful device information.

It is a fact that MIUI is one of the most complete customization layers that we can currently find in the Android landscape. Good proof of this is the number of secret codes that we can enable in the system to activate certain functions of the mobile device, functions that are often hidden from users because of their nature or because they pose a danger to the stability of the device. On this occasion, we have collected some of the most interesting Xiaomi secret codes that we have been able to find for Xiaomi devices.

The activation of certain codes depends on the version of MIUI, the type of processor (Qualcomm or Mediatek) or the base version of Android, so some functions may not be available on certain models of Xiaomi and Poco. Also, entering the codes will have to be done in the native Calls app, while we cannot resort to third-party dialers.

If the code in question does not work, we can resort to this other method to activate that menu.
