Security Updates and "feature updates" need to remain separate. Samsung is basically saying: "we are not going to be releasing any security updates until our next major OS release"... Unacceptable.
"Buy a Pixel if you're that concerned about security updates" - I'm sure that's what many readers would say but when the biggest manufacturer/seller of Android devices doesn't protect their customers by releasing security patches in a timely manner, how are we confident that every single purchase, post, view isn't being compromised.
I know I'm over exaggerating a bit, but security updates are not feature updates. They are instrumental. Will I keep using my Samsung GS8+ even though it hasn't been patched in 3 months. Yes.
But I shouldn't have to. Patch your OS Samsung.
