The capability to view and interact with two applications simultaneously on a single iPhone display, expected to be refined in the upcoming operating system, represents a significant advancement in mobile multitasking. This functionality allows users to, for instance, watch a video while responding to an email, or consult a document while participating in a video conference.
The introduction and subsequent improvement of this feature enhance productivity and user experience. Historical context shows a progression from single-app functionality to more complex multitasking environments. Such improvements allow users to accomplish more tasks without frequently switching between applications, streamlining workflows and maximizing device utility.
