Android 8 will have a lot of changes in comparison with earlier versions of the system, that's sure. However, so far we don't know too much about it. What's more, we still haven't received an official name of a new version of Android - in the opinion of many people, Google decided to give a name Oreo. But is that true? At this moment no one knows this. The name, however, is less important than the changes that await us in the new version of the system.
Sources that are close to the people working on the new version of Android report that Android 8 will bring changes to the notification, the new mode "picture-in-picture", limited activity of apps in background and much, much more. For more information we will have to wait, but certainly not for a long time - probably up to two months, Google will officially present the new version of Android.
