A:Answer I dont know how it works with Xfinity, but once you get to know how to ask Bixby a question, it works beautifully. Be specific. Example....Say something like "Bixby, Game of Thrones on Firestick" or "Bixby, Breaking Bad on Hulu". And in a second it will cue it up on the screen. I personally like it and it gets rid of my fire stick remote.
