Apple has released new iOS 9.3.1 update for iPhone, iPad and iPod touch devices. This new update to iOS 9.3 that was released last week addresses the issue in Safari, Mail, or Messages that causes the app to crash or the whole OS to hang where tapping hyperlinks.
Since the new iPhone SE and the 9.7 inch iPad Pro comes with iOS 9.3 pre-installed, the iOS 9.3.1 should be installed compulsorily for a smoother experience. Apple recently re-released new iOS 9.3 builds for older iPhones and iPads to fix activation bugs and bricking issue in iPad 2.
Still there is LTE connectivity issues for iPhone users on Sprint, following the iOS 9.3 update, so they are forced to use only 3G data. Sprint has acknowledged the issue and has confirmed that it is working on a fix. The update is expected soon, but no word on the exact time frame of the roll out.
