Lockscreen not moving

[acrux]

I found a solution that works for me. SFOS is missing a file in /home/defaultuser/  folder. So to fix this after the first failed boot reboot the pinephone with jumpdrive on the SD card. Then mount the data partition, go into /home/defaultuser and then run: touch jolla-startupwizard-usersession-done (you might need to be root to enter the defaultuser folder).
After this unmount the partition, poweroff the pinephone, remove the sd with jumpdrive and reboot.  Now the device unlocks

Yes, that workaround works as described some posts above.
But anyway - you can't sail very long, as as soon as the phone gets into powersave mode, it does not wake up any more.
