Depending on how you feel about the Android Pie navigation movement, you will be happy or disappointed to hear that they will not be available with this update. And when a notification appears, notifying you that the update has arrived, you must be really connected to the Wi-Fi network before starting the update process. Also, make sure the battery is fully charged before downloading and installation starts; after all, this is a large-sized update to swallow.
In addition to bumps up to the latest Android versions, this update includes improvements to camera applications including 1080p super slow-motion. It also carries the October Android Security patch, evidence that the update was originally planned for last month.
