how can I disable cast option?

thanks

 

You don't need to use it. Don't press the cast option or is that too simple?
What is the reason for asking?

 

Destroy all your tablets and smartphones, then cast is disabled for you only.

 

Sorry the question doesn’t make sense. Trying to understand here, maybe you meant something else?

 

Maybe you mean: 'How can I disable cast mode when I am in it?'. In that case (on my Android phone) there is a small cross in the upper right of the screen. If you press that you are asked 'are you sure you want to quit?'. Press OK and you are out off cast mode and back in the normal app. If you did not mean that, ignore this post.
