Re: No, no, no!
This is true for every manufacturer pushed update, who typically stop any support past not 6 months, but typically 3 in my experience. Samsung excluded
But Google started Android One, which I have on my Nokia 7.1. Bought it in march and I had a pack of updates last week since it is Google pushed and managed. I think everyone in need of a new Android phone should look at Android One if no other, for security reasons.
