Google officially just took the wraps off of Android Oreo, but there are still some questions left to be answered — most notably, precisely when each device will be getting the latest version of the mobile operating system. Due to Android’s openness and a variety of different factors on the manufacturing side, it’s not an easy question to answer, but we’ll break it down best we can.
First the good news: If your device was enrolled in the Android Beta Program, you’ll be getting your hands on the final version of the software “soon,” according to Google. Exactly what that means remains to be seen, but rest assured that you’ll be one of of the first people outside of Google to take advantage of picture-in-picture, notification dots and the like.
