I have seen an intermittent problem, but not sure if it is a software bug, or hardware problem. iPhone 5S, iOS 7.0.4
It happens when I get a notification, such as a new iMessage. I use the fingerprint sensor to unlock the iPhone when the notification pops up. When I try to tap the Messages App (which I have located in the dock), nothing happens. I try tapping other apps in the dock, same thing. When I try and tap other apps not in the dock or swipe to the next page, everything works fine. After a few seconds, everything goes back to normal and the Messages app opens when tapped.
Also when using the fingerprint sensor after a notification, why doesn't it go the app like happens when unlocking the phone with swiping or typing in the passcode?
