Nope, OP is talking about basic security patches, not Android version bumps. The S7 is stuck at Android 8 Oreo, and it would be a surprise if Samsung upgraded that to 8.1 or 9 (Pie).
Samsung is one of the worst vendors when it comes to Android updates, only flagship phones will see any major updates, generally for less than 2 years.
I don't intend to dispute this claim. In fact, it's still correct. And I'm biased, I've got a Samsung phone.
Still, opinion improved a bit when my S8+ got a march 2019 update which upgraded it to Android 9.0 (phone shipped with Android 7 in May 2017) and basically the same features/skin as what's just been released on the S10 lineup. Makes me hopeful that maybe they are improving their update game going forward.
