This is not working. I type 5 incorrect pins, I get a popup saying "You have typed your pin incorrectly <n> times. Please wait 30 seconds to try again." I click OK. The popup goes away. No "forgot pin" link comes up anywhere on the screen.
Now, in fact I configured the phone for face unlock, so if I power down I get another shot at face recognition. And if it works, I'm in. No. It powered up and brought me right to the pin unlock. No face attempt.
And even if I could get in with face -- I still can't change the PIN. And I can't reconfigure for a new pin because even though I am in the phone, it requires the pin again for reconfiguring lock.
Yes, I have a 3G internet connection, and yes, the phone is linked to my google account.
Phone is a Sprint Google Nexus (Samsung SPH-L700) running stock Android 4.3 (just upgraded OTA today).
Factory reset is looming in my future, I fear. But isn't there any alternative?
