Answer 1

Android One is the answer you are looking for.

The Nokia 7 Plus runs on the Android One platform, which ensures that you get a stock Android experience with minimal intervention by the phone manufacturer itself. The software experience is completely handled by Google, which ensures that you get the purest experience of the latest Android version.
Another advantage of using an Android One phone is that Google handles all the OS and security updates themselves, so you can rest assured that you will receive timely security patches and upgrades to the latest versions of Android much faster than other phone manufacturers who apply their own skins on top of the Android OS.
The phone is assured to get 2 years of OS upgrades, which is a really good sign. It is also mentioned that it is optimized for the Google Assistant. All in all, Android One ensures you gets the best Android experience with no clutter and seamless compatibility and integration with Google apps.

Thus, the Nokia 7 Plus runs on Android One, which ensures it gets the latest security and OS updates.
