Knock Knock Code turns off after restart

[godsidekurt]

So I noticed a bug twice today that is annoying...knock code stopped working randomly for me and went back to the default swipe lockscreen. Just now I did a restart and it happened again. Anyone else seeing this bug?

Mine did that once. On the AT&T model. No idea what set it off but it asked me for my password when I tried to activate the phone and then asked me to choose a lock screen. No idea how it got to those settings on its own.

I had a problem with knock code disabling randomly, as well. When I would wake up the phone it would ask for the backup PIN. At the time I was seeing this behavior, I had the phone set to lock 10 minutes after screen timeout. I changed that setting to lock immediately upon screen timeout. Since the change, I haven't seen the behavior anymore. My hunch was that the phone was jostling against my leg, turning itself on, and then thinking I had "failed" the knock code too many times and asking for the PIN. At any rate, I haven't seen that happen since I set the lock at immediately after timeout.

As an update, I think that if you have the phone with the screen facing toward your leg in your pocket, you are probably inadvertently pressing the power button. The power button activates the screen, which as it bumps against your leg or rubs against the inside of your pocket, creates false "failed unlock" attempts. At least I think this is why I've had this problem. Given the physical design of the phone, at this point I'm not sure how to avoid this problem.
