Unfortunately the employee did not indicate how to tell how much RAM memory a TV has.

Without the Mini Guide, to change the channel you have to [Return] to the first Stream screen ("Now Playing"), select "Live TV", and scroll to the channel you want to watch. "Saved", "Browse", "Search", and "Settings" are also options on that screen.

You would think that Comcast would have programed its app to respond to the Guide button on the Samsung remote, but apparently they have not.

@user_1bff6e Hello and thank you for reaching out over our Xfinity Community Forums. I am so sorry to hear about these issues you are experiencing, and I would be more than happy to help in any way I can! We do have a few troubleshooting steps that we can try. There are actually certain model Samsung TV's that the Xfinity Stream App no longer works with, so are you able to confirm the make and model of your Samsung TV? You can learn more about the specific Samsung TV's that no longer support the stream app here https://comca.st/3KLLfwF;

@XfinityChristopher : The short link you posted is broken. Were you trying for https://www.xfinity.com/support/articles/activating-xfinity-stream-smarttvs? If so, note that the page does not indicate which Samsung models support the Mini Guide, only which model years support the (formerly "Beta") Stream App for Partner Devices.

... Please try this link: ...

I already posted that link. What's the point of of posting a shortlink to something I've already posted??? And what's the point of drawing my attention to that shortlink???

Your time would have been better spent correcting the still faulty link that @XfinityChristopher posted. It was broken when posted, and it's still broken.

Xfinity is just looking for ways to make you rent multiple extra cable boxes. There’s no reason an app shouldn’t work on a smart tv that’s 4 years old. I’m switching to Verizon where this is not an issue.
