Expect Bug Fixes
You can expect the iOS 9.2 update to fix some iOS 9 problems.
Developers and testers using the iOS 9.2 beta have outlined a number of bug fixes that are expected to come with the public release. These fixes include performance enhancements focused on speed and improvements that will come in handy for Apple Watch users.
We'd expect some fixes for initial iPad Pro problems as well.
This is a milestone upgrade and milestone upgrades always come with a long list of bug fixes. Hopefully, the iOS 9.2 change log comes with a fix for those pesky iOS 9.1 Touch ID problems. Nothing is confirmed yet though.
