Thanks @vlagged for workaround document. I thought only I have this issue.
Also several times caught issue with black unlock screen after reboot. It stuck with loading indicator. The phone seems work. I can swipe left/right (swipe to event view, unlock view and swipe down top panel). When I swipe to unlock view - see black screen, but when I touch number area where numbers for enter pin code are located - the phone is vibrating on touch. One time I was able to unlock the phone. But when I locked phone again the loading indicator still there.
