I think it's a bit early to put that this or that phone is the best of 2017. Nokia 9, Mate 10 and Pixel 2 are still coming.
I'm not expecting the Nokia 9 to come in 2017. It *may* be presented still this year, but I wouldn't expect it in 2017 IF it ever comes (HMD is in the process of getting a new CEO and the new one might not be so permissive with lackluster phones like the Nokias 3, 5, 6 and 8 with the Nokia brand in them. And depending on how much the Nokia 9 changed from the plans, it might or might not actually be canceled).
LCD on Nokia 8 has the highest brightness on nits ever seen on a screen. Only Note 8 has a higher better brightness. HDR and other technologies are welcome. But, when you are under sunlight and can't see the manual controls from your camera because the screen is dim... Well... I prefer a screen with higher brightness always.
This is absolutely false.
The Nokia 8 clocks at 700 nits.
The S8 alone (NOT the Note 8) clocks at over 1000 nits.
The Note 8 at 1200 nits.
So yeah, LCD is terrible for sunlight readability. And if you indeed want to see the contents of your screen under sunlight...you'll be buying an S8 or Note 8 instead. Or, you know, any OLED phone. (If you want to learn more about OLED vs LCD, DisplayMate has an array of pretty good articles on the matter).
On software side, I like android pure over heavy TouchWiz or ****ty Bixby anyday.
That is personal preference.
I prefer phones without an incomplete version of Android.
For example, when I use split screen, I prefer to have an option on the bottom part of the screen to open another app from there instead of having to leave to the home screen, then look for the app I want, then click to open it and then the screen splits in two again as it happens with stock Android.
Or be able to open a theme engine and change the horrible colours Google picks for user interfaces.
Or having a blue-light filter built into the phone system that turns on automatically at the time I set it to turn, without needing third party, battery-consuming apps.
Etc etc.
(Oh and you can disable Bixby now anyway. And with effort, remap it to turn it into a useful button).
On cell signal reception, it's just better than the others (or as good as some other few smartphones, as Motorola and Huawei - LG and Samsung are always not too good in that department). Of course you can evaluate it, if you got another phone with the same service sim card on the side. Look at the technology they applied to get a better reception. If you're always on the center of big cities, good for you (in that case). But if you travel a lot or work in big buildings with a lot of concrete walls, that make all the difference.
Your claims on this are completely unsubstantiated.
If we're going to make random claims, then I can also use science to tell you that the Nokia 8 has a higher chance of terrible reception because the entire phone is made of aluminium instead of glass or plastic or anything else. With aluminium phones, the phone's reception is limited to the antenna bands, which limits its reception power. So I'm willing to wage that reception is better on phones without aluminium unibodies.
But again, none of that will depend exclusively on the phone. It depends more on your carrier and the places you go to. If you go to massive concrete buildings, your reception will be terrible or actually non-existent unless your carrier has service built into that building. Which is what happens a lot here in Europe. Because we have a ton of castles, palaces and colossal stone buildings, when companies have their offices in them, they have to hire a carrier to support the building with cell signal otherwise physics will prevent most phones from functioning because the walls stop the signal from the satellites and the antennas outside.
Listen, mate.
You CAN like the Nokia 8. It's totally fine. I really like the S7 even though I still don't like Samsung and I hate that the bloody thing lacks a camera button or double tap to wake. And despite the quality of the fingerprint scanner glass being crap. But I accept those as faults.
You can like the Nokia 8 because it offers you stock Android and you like that barebones version of the OS. You can like it because you prefer the cold feel of a metal phone. But to try to dismiss the many many faults the Nokia 8 has (specially considering Nokia's previous flagships), and use false arguments to defend it is just silly.
I can assure you no one, absolutely NO ONE inside Android Central (or, actually, probably inside all the Mobile Nations websites) would be willing to go around singing the praises of these new Nokia phones than myself. But I will not go as low as to deny facts just to praise HMD for a poorly done job.
The build quality on the Nokia 8 (like the 6, 5 and 3) is great, yes. The LCD's are good FOR AN LCD. But that's it. That's as much as I can praise these phones. Because everything else is just "meh". And the Nokia 8 being called a "flagship" is an insult to the Nokia brand it brings in it.
