This is an update we are working on. 

All of our apps support full screen feature. We have ROKU, FireTV, AppleTV, IOS, and Google Play. Furthermore, streaming on our website from any major browser works. I apologize if your Samsung TV doesn't support this, as mentioned before, we don't have an app specific to Samsung. Are you now having trouble with the app? I can't speak to any other provider. I'd be glad to help you one on one. You can message us directly here https://raceon.com/contact-us/

Kandace D Kerry You are going to probably have to reach out to samsung on that issue. We haven't made any changes to our video playback system.
