Apple just released iOS 9.2 update for iPhone, iPad and iPod Touch. It includes improvements and bug fixes for Apple Music, Safari, iBooks, and much, much more. To download the iOS 9.2, go to Settings–> General–> Software Update. The update log in all its glory is listed below for your reference. While none of these fixes were something I was definitely wanting or needing to have fixed ASAP, I can definitely relate to some of these issues happening to me periodically. iOS 9.2 has been in beta with developers since October, so it would appear as though Apple put some major time into collecting and squashing a great number of bugs iOS users have been experiencing.
One of the more notable changes that many users will find useful comes to us from the Safari view controller. Now with the support for third-party app extensions you will be able to access them in the Safari view of other apps.
