Following its usual pattern, Google has now started rolling out September Android security update for the Essential Phone, Pixels as well as supported Nexus devices. The update is available Over the Air, however, there are factory image flashes and full OTA zip files on its developer’s forum just in case you can wait patiently to get the OTA update.
For the Pixel and Nexus devices, the September security update fixes up to 59 vulnerabilities, improves battery charge in Retail Mode for Pixel 2 and Pixel 2 XL, while also bringing improvements to SW Version reporting and audio quality over car speakers for both the first and current generation of the Pixel Phones.
For the Essential phone users, the September Android security update is about 81.4MB with the 9.0.0 – Build PPR1.180905.036. The changelog includes a variety of security patches, Bluetooth car audio fixes, and accessibility fixes.
If you’ve got any of this devices, you can head straight to your phone’s Settings > System > More > System Update to check for the update, otherwise, you may have to resort to the factory image or you wait for the over-the-air (OTA) update.
