Screen Mirroring

We can mirroring the Xiaomi smartphone's screen to an external screen or monitor. To do this, both devices must be on the same network. This feature is similar to many third-party apps for screen casting or screen mirroring, but not all of them continue playback when the smartphone's display is off.

Note: If both devices are connected, we can transfer content by tapping the cast icon.
