What's the problem with having a smart TV but simply never using the smart functions? Mine works perfectly, once in a quarter shows some pup-up that I dismiss and that's it.
BTW I needed to connect it to local network because the remote has no button for changing brightness, so I do that from my PC.
I’ve heard this but I’ve never actually heard of any popular brand of TV that integrates cellular. I keep my LG and Sony TVs off the network and I’m 99.9% sure they have no way of accessing the Internet.
