Google sends out this month's security update; some BlackBerry Priv users are receiving it now42
The good news is that as far as Google can tell, none of the vulnerabilities were exploited. While the security patch is already available as factory images on the Google Developer site, the new builds will be received by the AOSP some time in the next two days. At the same time, Nexus devices will receive the update OTA.
One non-Nexus device that is receiving the update today is the BlackBerry Priv. To see if the monthly update has hit your handset, go to Settings > About phone > Check for update. The new build number is AAE298. Keep in mind that this applies only to Priv models purchased directly from BlackBerry. Those who purchased their Priv from a carrier will have to wait for their wireless operator to send out the update.
