I used to have numeric lock screen password. The virtual keyboard was the numeric phone dialing keyboard with big keys. All was peachy, I could keep the phone to lock in 30 seconds because entering the code was so fast, and I could do it without looking even on the virtual keyboard.
Then I got pushed a new policy from Exchange, which required a more complex password to unlock the phone. At the same time, lock screen password entry started to use the full QWERTY keyboard. This was all very annoying, but I had to change the code just to be able to use the phone again. Such is the life of a corporate peon.
Luckily, the policy change was an accident, and got reverted, and I could change my password back to the old numeric code. Only one issue: the keyboard still is in QWERTY mode! This is a major PITA and forces me to have longer lock timeout than I'm comfortable with, just to keep my sanity.
How can I change the lock screen password entry back, to use the numeric phone dialing keyboard?
I hope there is some other way than resetting the whole phone! But if there isn't, I'd like confirmation that resetting the phone does indeed fix this. Does anybody know this for sure?
