[Update: Although details around the problem with iOS 9.3 links causing hangs and crashes remain sparse, it appears to be related to the third-party apps a user installed on the system. We have been able to take an unaffected iPhone 6 and iPad Pro, install the Booking.com app, and then observe Safari consistently hanging when long pressing a link. We do not recommend repeating this however to see the bug for yourself, as the problem appears to stay around. Our test devices continue to exhibit the crashing bug after uninstalling the app and rebooting. We are not sure what exactly causes the issue and thus do not know what class of apps cause the problem to arise. It is likely not limited to just one app, but we are yet to find others. Apple is yet to comment officially on the issue.]
Readers are reporting a strange bug with iOS 9.3 (and older versions apparently, exact characteristics of affected devices is unclear), primarily affecting the latest Apple devices, iPhone 6s and iPhone 6s Plus. The issue has also been reported on older phones and some iPad models as well. The cause is unknown, but many users are finding themselves unable to open links in Safari, Messages, Mail, Notes and other apps. Instead of visiting the target website, the app crashes, freezes or hangs. Hundreds of reports have already been posted about the iOS 9.3 problem on the Apple Support forums.
