Multitasking in different formats has been present in Android OS since some time, but only with the release of Android Nougat version, it should have been a more rational and orderly form with three separate multi-windows: Split-screen, Freeform and Picture-in-Picture (it became available on smartphones even earlier Android Oreo).
But the split-screen mode, which appeared in Android some time ago, still has a significant limitation. Allows you to split the screen's working area into equal parts for two different applications at the same time, but you can only work with one of the applications.

That is, if you simultaneously run two different third-party applications, then after switching to one of them, the other is paused. But that will soon change. And future flexible smartphones will help to change this.

Google is already launching and running in real time for several applications at the same time on its Pikel smartphones. In addition, Samsung also offers similar functionality for its latest models using the special MultiStar module in Good Lock software. But with the release of Android 10, this feature will become standard and will be distributed to more models of smartphones. In addition, it will have more third-party applications that support this mode of work.
