Android 8.0 is rumored to arrive as "Oreo," but we also saw it being called "Oatmeal Cookie" although Google said nothing about this so far. On the other hand, we know that Android 8.0 should launch in the third quarter of 2017 if everything goes as planned.
The Android O update for Google Pixel and Nexus devices should arrive for everyone in the first two weeks of August, claims Android Police editor David Ruddock, quoted by Android Authority. Back in early June, the third developer preview build became available, and in about two weeks, the final beta should hit the web as well.
Android 8.0 Oreo/Oatmeal Cookie/<insert other possible name here> is expected to integrate Picture-in-Picture mode, Notification Dots, improved text selection, autofill, improved notifications, app badges, and much more. We will get back to it soon since the last beta to launch before the public release should arrive this month, as mentioned earlier.
