Casting vs
Casting allows you to play content streaming on your phone from a compatible app directly to your Roku TV.
Casting is a convenient option for watching videos or listening to music on your TV without having to physically connect your phone.

You can start playback on your phone and then beam it to your Roku TV or streaming stick, and locking your phone won't affect the media playback.
This means you can use your phone to manage content playback, such as pausing or skipping tracks, without interrupting the media playback on your TV.
Mirroring, on the other hand, will mirror your Android phone's screen to your Roku TV, which is great for viewing photos and videos locally saved on your phone.
You can also use mirroring when an app is not available for Roku OS and lacks support for the Cast protocol.
Mirroring is not possible with the Roku app, but you can use it to mirror the files stored on your phone to your Roku TV.

Mirroring and Sharing
