That's hardly an answer, though.
With the FPS on my 3XL and previous phones, *I* decide when I want the phone to unlock and, yes, it goes instantly and directly to whatever screen or app it was on when I last locked it.
What you are proposing is that I either inconvenience myself one way (phone constantly unlocks unintentionally) or the other way (phone requires me to swipe away the lock screen). Both options suck and, frankly, are a stupid design decision.
It is the answer... That's how the phone is now. So that's definitely the answer.. the only other is buy another phone.
