A:Answer April 2018, I am using the Spectrum app on this model TV and it works great. The interface looks and operates just like the Roku app, if you've ever seen it. The only issue I had was the Samsung app store didn't offer Spectrum app while I was setting up the TV. Later I used Search to find it and then it installed smoothly. Works great, and is less cluttered than the Roku version since this Samsung one apparently only offers the highest resolution suitable for the TV and skips the low-res options, which the Roku doesn't do. The Smart Hub is brisk, and it allows you to rearrange tiles to put favorite apps first. There is also a setting in the menus that makes the tv boot up and use the last app used, instead of show ya the hub and make ya pick an app every time. Very pleased with this model's performance and features.
