This isn’t a full blown software update, so you will not be seeing any new features as such. As per the change-log, the update installs the December Android security patch on the device. Apart from that, there aren’t any changes.
The update weighs around 97MB in size and can take up to a few days to be available for all. This is based on Android 8.0 Oreo, as the Nokia 8 received the Oreo update late last month. Other Nokia phones such as the Nokia 5 and Nokia 6 would also be getting the Oreo update soon.
If you’ve got a Nokia 8 smartphone, we recommend that you install this new update as soon as you get it. Security updates are quite important as they patch new vulnerabilites and improve the overall security of the phone.
