IPad 2
In late March 2011, the iPad 2 was released with iOS 4.3, which had Airplay Mirroring and Home Sharing with other features. On October 12, 2011, after the release of the iPhone 4S, the iPad can upgrade to the iOS 5.1 update which released more than 200 new features to iOS devices including Game Center, iMessage, Reminders, and a new notice system, using a new style instead of the old “alert” style. Later, iOS 5 was available for the iPad 2, which released more than 200 features on the iOS devices. On September 19, 2012, iOS 6 was released for many iOS devices, but not all features are available on the iPad 2. The upgrade was an update package and had a lot of new features, which had a map software made by Apple named Apple Maps, a "Clock" app, which has a timer, stopwatch and alarm, and Facebook with other new features. In 2013 the iPad 2 received iOS 7, but some features were not available, with AirDrop only being available to the iPad 4 and later, and no Siri. It later got iOS 8 in 2014, being the first Apple device to get five versions of iOS (4, 5, 6, 7, and 8). But most of its new features do not work on the device due to old parts used in the tablet, and its performance was poor. Users have also reported problems on the device. In 2015, the device got iOS 9, being the first device to get six iOS versions (4, 5, 6, 7, 8, and 9) but many features weren’t on the tablet either due to older parts in it.
