Android Oreo is the eighth version of Google’s smartphone OS, released in August 2017. Following a quick five-minute play with the operating system on an updated handset, you could be forgiven for thinking that nothing has changed. The focus of this update is more to do with adding low-key features and tweaking functionality added in Android 7.0 Nougat, such as the notifications system.

Android 8.0 – Picture-in-picture

One of the other lead features of Android 8.0 is picture-in-picture. This lets you open up a small video screen that floats above other apps.
Samsung actually offered this feature five years ago in the Samsung Galaxy S3, before quietly retiring it in recent generations as part of its move to makes its phones classier and less complicated.
Frankly, in Android 8.0 it’s as pointless as it was in old third-party Android UIs – unless you have a specific need to take notes from a video. And then it suddenly becomes a godsend.
