Default [Q] What is the default pin for the screen lock?
I just installed nightly 105. Because I had some battery problem, I wiped dalvik cache and then I found that my password to unlock the screen does work anymore. I've installed nightly for many times and this is the first time I wiped dalvik cache. Is there a default password for the lock screen? Or is there a way to bypass the lock screen? Thanks a lot in advance.

Update: after I rebooted a couple of times, suddenly the old pin worked again. Not sure why.
