Interesting Bugs?

• Clearing passcode delay bug

–Doesn’t immediately interrupt delay

–Doesn’t clear failure count

• Don’t mistype your new passcode the first time

• Otherwise count continues, you’re delayed again

Lock Out Bug

• Clear simple passcode with panel up

First, after several passcode failures, a delay gets added between

attempts. If MDM clears it, the device won't immediately open -- the

current passcode entry delay must ﬁrst timeout (which can be up to an

hour).

Worse, the failure count doesn’t appear to be cleared. So you get

unlocked, into the device, and set a new passcode. Then if you lock it,

and immediately mistype the passcode, you’re back where you started

-- if you had 7 failures before, then that’s # 8, and you now have to wait

15 minutes to try again.

Another bug: when you have a simple passcode, and it’s cleared while

the numeric keypad is up. When that happens, entering any random 4-

digit code will let you in, while hitting “cancel” kills the panel, but also

kills the “swipe to unlock”. So the device is locked, at a (mostly) blank

screen, and you can’t do anything at all other than power-cycle it.
