Apple today released iOS 9.3.1 to the public, marking the first update to iOS 9 since iOS 9.3 launched on March 21. iOS 9.3.1 comes just over a week after the launch of iOS 9.3 and likely brings a fix for a significant web link crashing issue that has been affecting many iOS users.
Today's iOS 9.3.1 release is available as an over-the-air update for all iOS 9 users and it can also be downloaded through iTunes. iOS 9.3.1 is the seventh update to iOS 9, following iOS 9.0.1, iOS 9.0.2, iOS 9.1, iOS 9.2, iOS 9.2.1, and iOS 9.3.
Shortly after iOS 9.3 was released, a number of iPhone and iPad users found Safari, Mail, Messages, Notes, Chrome and some other pre-installed and third-party apps would crash or freeze after tapping or long pressing on a web link. While most users affected were on iOS 9.3, some customers on earlier versions of iOS also complained of crashing problems.
The exact underlying cause of the problem has not been discovered, but there is speculation that it is related to Universal Links and the Shared Web Credentials daemon, which allows apps and websites to share login credentials. No quick fix has been available, but shortly after the bug was publicized, Apple said it was working on a fix and has made good on that promise in the iOS 9.3.1 update.
