Android Smart phone casting to 50'Samsung Crystal UHD

I am not seeing the video when I pair my Phone and Tv. I have sound but nothing on the screen.

Hi LadyBird411,

Thanks for visiting the Google Nest Community. Let’s get this sorted out. What type of Chromecast device are you using? How far is your Chromecast device from the router? Were you able to cast just fine before? Are you experiencing the same behavior with all streaming apps you tried to cast, or only with a specific app? What’s the app name?

Regards,
Alex
