Bests & Worsts Reviews from Amazon

My first 4K television and picture quality is fine. Disappointed over a few things though. First, I dislike the UI (User Interface). Have a large collection of movies stored on a NAS (Network Attached Storage) device. The TV found the DLNA server just fine, but the folder structure is not modifiable and is worse than any of my BluRay players. Takes forever to scroll though the movies. Second, even though I have a Samsung SmartThings hub, it will not connect to the TV. It's the same manufacturer. How can that be? Third, because the TV won't connect to SmartThings, I CANNOT control it via my Amazon Alexa devices. Fourth, you can't edit all of the inputs. I don't need or want my DirecTV HDRs showing up as media servers. I just want the DirecTV satellite it's connected to via HDMI, my computer connected via HDMI, and my DLNA NAS server. In short, the TV is fine, but the software running on it falls well short of what I expect.
