The Nokia 8 has received regular updates over the last 12 months and Juho Sarvikas has said Android 9 plus further camera developments are coming to the Nokia 8, what more do you want?
You are expecting features to be added that were never on the phone to start with, when a car maker brings out a new car do you expect its features to be implemented on the older model?
For some historical perspective, Nokia 8 did not even have the Android 8 beta at this point last year available yet (the beta was released in late October). Regarding the current situation, very few devices from any manufacturers in general have Pie available at this point; in the Android version dashboard updated 28th of September, Pie was not even listed yet, meaning that less than 0.1% of Android devices that visited Play Store during the previous week were running it. So it's not like 8 is late receiving the update, as literally less than 99.9% of Android phones have it at this point.
I'm as interested as anyone about getting the update, but considering the above, I don't feel left out at all for not having Pie yet on my Nokia 8. Now, if there's no beta in within, say, a month or so, I might be getting a little annoyed though.
Also to give this a little extra perspective, i have a Moto G5 Plus sat here, it is 18 months old and it is still running Android 7.0, it has not had a single OS update and has had only 3 security patches in its entire life.
Apart from the Moto G5 was one of the highest selling phones of last year and the Nokia 8 came absolutely nowhere near it in terms of sales then i guess you are right, it wasn't successful.
If you aren't asking for extra features what is adding "live images and much more"?
The Nokia 8 is a year old and newer handsets will always get priority over older handsets, i suspect once Android 9 is released for the Nokia 8 then that is your lot, it will fall by the wayside.
Our only hope for the Nokia 8 is that HMD can finally sort out the camera app before the phone is put out to pasture.
It is clear the Moto G5 analogy regarding updates went clean above your head.
If you love OnePlus that much then maybe you should have bought a OnePlus. Given they only release 2 phones a year maybe they have more time on their hands to pander to your specific needs and requirements.
