Nokia Mobile still keeps its word about making its smartphones secure and up to date. It might not release the update the same day as Google does, but the release schedule is timed well. Nokia 7 Plus started receiving the Google Security Patch for May. The update is 84.4 MB large and the installation went smoothly. The update just brought the security patch, nothing else.
Do check your beloved 7 Plus and be kind to verify if it is available for your device also.
