Just after 10 days after the public release of iOS 9.3 on 21st March, Apple has released iOS 9.3.1. iOS 9.3.1 update addresses a bug that caused a device to crash after tapping on links in Safari and other apps.
There are no new features being introduced to iOS 9.3.1. Its only aim is to fix the nasty big that casued device crash issues. iOS 9.3.1 changelog is short and simple: “Fixes an issue that caused apps to be unresponsive after tapping on links in Safari and other apps.”
