I tend to agree. There is a lot of latent potential in the Nokia 8, that just isn't being tapped into by HMD. To me, the Nokia 8 is good but not that good.
The early marketing was that the Nokia 8 would have plain Android to enablle a quicker update to Oreo. Now that the Oreo update is well under way, HMD must turn to improving the overall software feature set of the Nokia 8 otherwise there's not much to differentiate it from a cheap generic phone also running bog stock Android.
My Nokia 8 replaced a BlackBerry Priv. BlackBerry also prided itself on rapid security updates. Security is or has been BlackBerry's main selling point. An enhanced feature set over stock Android didn't stop BlackBerry releasing the monthly Android security patches in a timely manner so there is no excuse for HMD/Nokia either.
