The latest version of the iPhone and iPad operating system is iOS 10, although there have been a few updates since its launch in September 2016. The current version is iOS 10.3.1. iOS 10 has proved popular since its release. As of 4 January 2017, just under four months after iOS 10's release, Apple reported that 76 percent of active iOS devices are running version 10, with 18 percent on iOS 9 and just six percent on iOS 8 or older versions.
Major versions of iOS are released annually. The current version, iOS 10, was released on September 13, 2016. It runs on the iPhone 5 and later, iPad (4th generation) and later, iPad Pro, iPad Mini 2 and later, and the 6th-generation iPod Touch. In iOS, there are four abstraction layers: the Core OS, Core Services, Media, and Cocoa Touch layers. iOS 10 dedicates around 1.8GB of the device's flash memory for itself.
