Nokia Mobile’s promise to deliver regular security updates is here to stay. They have just started pushing the July security patches to the Nokia 8 Sirocco and also to the Nokia 7 which is not an Android One device.
Both devices are receiving updates lesser than 100MB in size and offer only the Android security release. You should receive an update notification, however, if you don’t, you can always perform a manual check.
As with the latest Android, the updates do install without requiring the phone to be shut down. You will only need to restart it after everything is done. So, that is just about 2 minutes of downtime for the security release which might fix some severe bugs.
