Nokia 7 Plus started receiving the Google Security Patch for December. The update is 106.7MB large and brings just the security patch, nothing more. The previous update V3.39B brought some improvements to the device. If you are a proud owner of Nokia 7 Plus, check for the update availability, it should be there.
The installation went fine on mine 7 Plus, but if you notice something odd, tell us in the comment section.
