I concur. I say don't buy Samsung or LG. Both are good at ignoring you after they sell you their TVs. I have one from both. They advertise all the brightness, colour crap which no one tell a difference in and completely bypass app and os support. Trust me YouTube stops working on TVs and sure enough other apps follow. Then you have to buy an external box like fire stick/shield anyway. I think I will be buying a "good enough" cheap tv and adding a media player I mentioned earlier and avoid these pricier fancy TVs.
Amazingly none of the reviewers seem to ask the reps why consumers should buy their stuff when they ignore them anyway
