At the phone launch event in Barcelona, HMD Global said all Nokias from Nokia 3 and above would be part of the Android One program, meaning they will receive security updates up to 3 years after their launch.
The Android One program is a line of smartphones with pure Android, a limited amount of pre-installed apps to allow more storage and highest grade of security. Phones under this project are the first to receive the monthly updates, and in this particular case, the Nokias will get Android P once it arrives.
The full list of Nokia Android One smartphones is: Nokia 3, Nokia 5, Nokia 6, Nokia 6 (2018), Nokia 7, Nokia 7 Plus, Nokia 8, Nokia 8 Scirocco. The names missing are Nokia 1 which is under the Android Go program for affordable devices and the Nokia 2, which is simply left behind.
Phones that did not arrive with Android 8.0 out of the box will get the new Oreo 8.1 in the following weeks. The new OS brings detailed notification settings, picture-in-picture mode, Instant Apps and plenty of new emojis.
