It's startling how bad #Apple's usability has got since Steve Jobs passed away. My latest, and favorite yet #WTF:

The phone displays a "missed call" notification on the lock screen, but no other information, reasonably enough, because the phone is locked. I tap the mesage. It gives me an unlock keypad (I'm masked). I type my PIN to unlock it, and it immediately .... wait for it ... CALLS THE CALLER BACK. It doesn't show me the detail and offer to to do it, it just does it. (Naturally, it was a mystery-meat 866 number. I stopped the call, of course).

Imagine anyone thinking that should be the default action on tapping a missed call notice with no visible phone number.
