My Huawei P10 also received security update few weeks ago. It got 2 major Android updates (7 -> 8 -> 9) and while the last update was probably the last, it got more than 3 years of SW support (released March 2017).

I really think Google could do better. Sure, you don't have to wait long for new Android version as with other manufacturers (e.g. Huawei), but 3 years is nothing to applaud Google for.

Fair enough, and props to Samsung for that.
