I use a numerical PIN to lock my Droid Incredible 2, and it works about half the time. The other half of the time, the PIN pad doesn't appear and I go straight to my home screen.
From my lock screen, when I pull down on the bar I should next see the PIN pad where I enter my PIN. However, about half the time, I pull down on the bar and go straight to my Home screen, just as if I had never set a PIN.
How to fix this - get the PIN pad to appear every time?
