The iteration of Google’s mobile operating system prior to Oreo offered a refined visual and interactive experience to users and developers through its user interface, often distributed as a test version. This allowed for broad testing and feedback collection before a wide-scale deployment to the Android ecosystem.
The significance of these testing phases lies in the ability to identify and address potential software defects and usability issues before the general public accesses the software. Historically, this approach has been critical in ensuring a smoother transition and user adoption when a new operating system version is released to device manufacturers and end-users.
