I've had Samsung on "boycott and complain" list, anytime someone asks me for a recommendation and samsung is an option i say "avoid samsung"; I started boycotting them after they told me to pound sand when i had an issue with my $800 4k monitor a couple months after i bought it. I had also bought a new samsung refrigerator around that time as well, and among other issues, it leaked water from the ice machine starting about 1 year after i bought it. I've had to replace the mainboard in it, as well.

So no phones, appliances, laptops, TVs, memory sticks, SD cards, and whatever else they make. Even if they magically got a better reputation for customer service, the shenanigans with the smart TVs is enough to keep the boycott up.
