The upgrade is finally here, which is absolutely good news for all apple users. The iOS9 is Apple’s latest operating system operating on devices such as iPhone and iPhone. This new operating system was launched on September 16, 2015. The iOS9 is an enhanced version of the iOS8 and ios7. In comparison to the iOS8 the iOS9 boasts slightly improved content, upgraded features, better functionality, and performance enhancement. iOS9 most major focus was on “intelligence” and proactivity. This allows for the devices to act more like the user’s personal assistant, making recommendations, opening apps before the user realizing that he/she need it. Needless to say, as a result of these upgrades the operating system is expected to be more user-friendly.
