September Android Security Update OTAs Starting to Arrive
Just two days after their initial release, the Over-the-Air (OTA) updates for the September Android Security Update are starting to hit Nexus devices. While they are sporadic at this early point, owners of Nexus devices should start looking for the updates to hit their devices over the course of the next week. In my case, my Nexus 6 (running Marshmallow) was updated while my Nexus 9 (running Nougat) also received its update to the 09-06-2016 patch.
It should be noted that not all Nexus devices have received their Nougat update yet so it is possible that you could get a double OTA update over the course of the next week or two.
