Secure screen lock methods (pattern, password, pin) cannot be used after upgrade.
Which version of the software are you running?
I upgraded from Android 7 to 9 recently, while no screen lock was configured. After the upgrade, I can type a PIN code or give a pattern, but nothing happens: no PIN code or pattern gets set.
I expect a PIN code to be set, and the screen to be locked after a few minutes,
Steps to reproduce
Upgrade from Android 7 to 9? I cannot do that again.
Is there a workaround?
