Just got a new Nokia 6 smartphone, with lock screen offers from Amazon. Only $180 cheap. It runs Android 7.1.1 Nougat, stock except for the lock screen ads. Ars Technica likes it. It has been less than a full day, but I like it so far.
It looks nice: I got the copper version. And it's the biggest phone I have personally owned. It's not particularly fast, but it's a secondary phone that I use for work. The nice thing about the big screen is that Nougat enables split screen multitasking. Just touch and hold the "switch app" button (lower right, with the square shape icon). It also conveniently flags spam phone calls.
Here's the official product image from Nokia, the split screen, and the spam warning:
