I'll update with some info from some users over on android central (might be better to chime in there too).
Fingerprint sensor isn't great. Camera though, some of the photos do look really nice, I do prefer them over a S10, but the differences are subtle, and you don't get this profound difference. I would say this is basically because the cameras are getting to a point where they're good enough for most shots. The quality is decent and for the most part, if you need to zoom in to blow up pixels, and compare against other cameras, well, the quality is pretty good already isn't it.
With that said, speed improves if the raw format and depth sensing is turned off. If you want a point and shoot, well this is the way to go, as the files appear to be really large if the depth sensing is on.
It's really subjective, and I'm aware that opinions vary. Some things bother some people, other things don't. It also appears that updates are slowly addressing some of the bugs.
At this stage though, I bought a Nokia 8 and don't think I'll change really quick. The Nokia 9 may become a great phone, but I'm starting to get a feel for reading between the lines of corporate speak, so I'm quite certain another model is being planned sooner rather than later.
I hope Nokia listens to some of the criticism of the phone, and corrects a few of the issues, but when any company says that an otherwise mainstream device is 'like a limited edition' it just means that they're not planning on selling a whole lot, and they're not planning to do additional production runs. If people queued up and bought out all the stock immediately, then you'd see that it very quickly wouldn't be all that limited.
A consideration for me is also, I don't know how quick the rollout for 5G will be, but I'm disinclined to go for a premium phone if it's going to be superceded by improved technology relatively soon. I prefer to buy a phone and run it until it's dead.
