Modern TVs often have limited functionality, and it is at this point that the Xiaomi Mi Box 3 comes to the rescue. This compact console turns any screen with HDMI into a powerful multimedia center based on Android TV. The process of initial configuration of the device seems simple, but has a number of nuances, ignoring which can lead to problems with connection or stability of the system in the future.
