Along with Nexus devices receiving OTA updates for July’s security patches, BlackBerry Priv users will also join in on the latest Android security patches for those devices purchased unlocked from ShopBlackBerry or Amazon.

The update is around 95MB and includes the same security fixes that were patched in this month’s security update.
If you haven’t gotten the OTA yet, you should be getting it over the next few days. Alternatively, you can manually check for the update by going to the Settings app, then tap ‘About’, and check for updates.
