Lumia 950 - black screen while trying to unlock

[Ferjim77]

I use autobrightness and have no problems any more, without the "hey cortana" option. Also have iris scan and no problems.
Hey Cortana was the problem for me.
You can try it and use autobrightness.

I've been having this issue with my 950 for over a year. In the past two weeks it's become especially bad. I'm happy to try the suggested fixes and won't particularly miss the "hey Cortana" feature because I've never been able to actually make it work on this lame, rubbish, utterly stupid, worst-phone-ever device anyway.

I got same issue, without glance screen. Restart will fix problem but it came back in a while.
If some of us have same issue I believe its software update problem, not hardware.

Same situation is here with my new Nokia Lumia 950. I think that definitely is the software issue.
