Apple has released iOS 9.3.1 for the iPhone, iPad and iPod touch. It’s available to download through Software Update or at iTunes.

The bug fix update to iOS 9.3 fixes a problem in which apps (and sometimes iOS itself) would crash or hang when links were tapped. iOS 9.3 also featured an Activation Lock bug that affected older devices, including the iPad Air and earlier and iPhone 5s and earlier.
