Multitasking in various forms is present on the Android OS since time immemorial, but only by releasing the Android version of Nougat, it takes a more rational and organized form with three separate multi-window modes: Split, Freeform and Picture-in-Picture screens (becoming available in smartphone as early as Android Oreo).
But the Split screen mode, which appeared on Android some time ago, still has a significant limitation. This allows you to divide the screen workspace into the same section to run two different applications at the same time, but you can only work with one application.

That is, if you run two different third-party applications at the same time, then after the transition to one of them, the second is paused. But that will change soon. And future flexible smartphones will help to change this.
Developer community XDA Developers write that in the next version of OS Android Q (Android 10), the Multi-resume function will appear, which will eventually provide an opportunity to work simultaneously with two or even three applications running on multiple windows.
Google has launched and works in real time for several applications simultaneously on its Pixel smartphone. In addition, Samsung also offers similar functions for its latest models through the MultiStar module specifically in Good Lock software. But with the release of Android 10, this function will become standard and will be distributed to a large number of smart phone models. In addition, there will be more third-party applications that will support this operation mode.
