This is the latest OS Update Schedule from Rogers. It's usually updated on Fridays, but last week it was on Saturday. Today being Canada Day, I think that it's unlikely to see an update from Rogers, or Telus.
You'd like to think that updates would come to the recent Flagship devices first, and then in descending order, but that's not how Samsung seems to work.
Was a bit better for my S20 Ultra, actually available on the 6th with the June Security Patch.
But, hey I don't have anything to do with when, or what.. Just wanted to make sure you saw it 🙂
I wouldn't say "usually". It's far more rare to receive an update that includes feature changes.
Samsung just isn't very good with releasing updates, although they are definitely better than a few years ago.
