I am extremely new to really using my Roku. Even though I have owned the tv since 2016. My tv is TCL 28S3750 28-Inch 720p Roku Smart LED TV (2015 Model). I wanted to get rid of my Xfinity boxes but the remote that came with the tv is so primitive. It would take forever to get around in Xfinity.
I don't know if I can get more options with a different remote or should I start over with a new tv? Or what would happen if I put a Roku stick into the tv? Would it upgrade to the newer version?
I assume you want to use the Xfinity app on the Roku, and use the Xfinity remote within the Xfinity app? Unfortunately it doesn't work that way, as Roku apps only take remote codes from the basic navigation keys in the Roku (play, fast forward, ok, Up, Down, Left, Right, Back, Star, A, B, and Ok)..
Besides, your video will probably be degraded and delayed if you use the Xfinity app rather than the cable box. At least it is with Spectrum's app.
