@VKS3385 That's good news if you're covered financially.
Regarding Twitter, last summer some of us here tried the social media route but got nothing but a few patronising and totally incorrect responses from Samsung.
The problem with this issue is that it's quite subtle for those that don't have the TV, and many don't understand it. I'm sure a lot of owners don't notice it either as they use external boxes and Firesticks for smart apps.
I did not read the entire thread so forgive me if I'm repeating other posts.
But I had the issue with my 4K TV and they did come out and replaced the motherboard.
Problem is the TV comes with preinstalled apps which cannot be deleted, I only had enough space to install 2 apps.
Samsung kept pushing new apps to the TV which ultimately took up all the space leaving me with zero space to install apps that I actually wanted to use. Samsung must get compensation for this from the app people (Netflix, Hulu etc.)
To me this is completely insane.
Anyway, when the space was completely gone I called them back the the tech I got did know about the USB thumb drive, so I connected a thunb drive and I could download and use apps on the thumb drive but I believe this is very poor practice by Samsung; now maybe they all do it but I only have a Samsung smart TV..
