I have no idea what triggered the following, so it doesn’t make sense for me to use the bug report template.
Suddenly, my XA2 (with 4.0.1 installed at the time) stopped to show the lock screen. The setting still shows that the phone should lock immediately. I can’t lock the screen regardless whether using the hardware button or using the lock on the pulley from the main screen. If I use either, the screen goes dark as expected and I can’t interact with the screen anymore (so that’s good), but as soon as I hit the hardware button again, I’m right back where I was before – either in an app or on the main screen.
The phone is behaving as if the lock screen app has completely vanished from my system (btw: I assume it’s a dedicated app that I could just as well call from the terminal to maybe trigger some logs / error message, but I don’t know the name of the app, any hints?)
On a side note and maybe unrelated, maybe not, I lost a lot of app icons on the main screen after rebooting.
Upgrading the phone to 4.1.0 did not fix anything for me, I still can’t trigger the lock.
Does anybody have any hints what else I could look at?
