The next release of Android is officially here and comes with some superhero powers to help you get the most from your device.
Ever try checking your schedule while staying on a video call? Android Oreo makes it easy with picture-in-picture, letting you see two apps at once: it’s like having the power to be in two places at the same time! Overwhelmed by notifications, but missing the ones you care about the most? With Android Oreo, notification dots let you tap to see what’s new in your apps — like the important ones you put on your homescreen — and then take action on those notifications quickly.
OTA updates are going out but images for Pixel/Nexus can be downloaded here: https://developer.android.com/about/versions/o/download.html
