iOS 9 Problems
iOS 9 problems continue to be a problem for many iPhone, iPad and iPod touch users and iOS 9.1 Touch ID problems are among the loudest complaints about iOS 9. Fortunately, you don't have to wait for Apple to fix most of these issues.
These are fixes for most of these iOS 9 problems and our list of fixes is a great place to start. We recently updated our list of fixes with some remedies for Touch ID issues so make sure you take a look at those before you bring your device into an Apple Store.
Apple hasn't confirmed an iOS 9.1.1 update yet so you might be on your own until the iOS 9.2 update arrives. iOS 9.2 is slated to bring several bug fixes for iOS 9 problems though its change log will be limited to a handful of fixes.
If you haven't moved to iOS 9 yet, make sure you commit these fixes to memory so that you're prepared in case you do run into something.
