Cast to Flex

How can we cast from a mobile device to Flex? I even have Xfinity as a mobile provider but can’t figure out how to cast what’s on my IPhone to my Samsung TV where Flex is connected and is otherwise working fine.

Welcome to the Xfinity Forum and thank you for posting your question here. To cast select apps’ content from your mobile device to an X1 TV Box or Flex streaming device, you’ll need the following:

  • A supported Xfinity Gateway with Xfinity Internet service.
    • Supported Gateways: Arris or Technicolor XB6, Arris or Cisco XB3
  • An eligible X1 TV Box as part of your TV subscription, or a streaming device with Xfinity Flex service.
    • RNG150 and Pace XG1v1 X1 TV Boxes are not eligible for mobile casting.
  • A mobile device connected to your in-home network.
  • Supported apps include: Netflix, Spotify and YouTube.
    For information on each mobile app and how to cast, please refer to:

Turn On or Off Mobile Casting to Your X1 TV Box or Flex Streaming Device

To turn on or off mobile casting:

  1. Press the xfinity button (X1 or Flex) or home button (Flex) on your remote.
  2. Use the right or left arrow buttons to get to the gear icon, then press OK to go to Settings.
  3. Use the up or down arrow buttons to get to Privacy, then press OK.
  4. Go to Mobile Video Casting and press OK to change the setting as you’d like.

Note: Mobile casting is turned off by default on X1. On Flex, it’s defaulted to on.
