I'm facing the same problem. It's not even been a month to my new phone and this has happened twice and it doesn't even reboot.
bought nokia 5.1 plus the day before yesterday, the problem started yesterday itself, everything was working except the screen went black and today it happened once again, NOKIA either you fix it up through OTA or i am returning this that to with a legal complaint filed, THANK YOU
I also faced this issue twice. This issue is occurring randomly and there are no specific steps to reproduce it. First time it happened when I was on a call and second when I woke up in the morning and tried to access my phone. The screen gets completely black and have to restart my phone by trial and error method. I am afraid of the consequences if this happens in some emergency situation.
Please release a software patch asap to fix this issue.
