They’re probably talking about Samsung TVs, not their android phones/tablets. Installing jellyfin on those things can be a chore. My experience with LG was similar. The official build was out of date and riddled with issues that didn’t exist on other versions. It refused to play videos that worked well enough on other devices, transcode or no.
There’s the Elven Rope that’s light as a feather and strong as steel. No reason there could not have been the Elven Condom that’s thin and impermeable.
