    I've been seeing this issue for a while now, at least a couple of months. I don't use a screen protector, I do use auto-brightness and glance. I don't use the iris-scan to unlock, although the red LED still comes on, especially when I'm getting this black screen. I struggle to think how taking the SD card out, booting, and then replacing the SD card would affect this at all. I think the real problem must have something to do with the IRIS scan, since that's the only physical clue I have to work with - I've got it shut off, but with the black screen, I often get the red iris-scan LED.

    This is the type of junk that should happen on fast ring, not production.

    Hi,
    If you put light on light sensor and the screen is on max brightness, light off and screnn is going back to set brightness.
    have 50%+auto - time for going back is 10 seconds or more
    Can you test it ?
    L950 is on last W10M public update.

    Not sure if this is the same issue you're facing, but sometimes when Im clicking on the unlock button it won't show me the screen, but I still can unlock it and after a few seconds it shows me the tiles but with decreased brightness, I guess it has something to do with the brightness sensor

    That does describe what is happening on my 950, but the really bad part is when I have an incoming call, the screen is black and I cannot answer it. And texts.

    If I press the key to wake the phone up, it hangs the call up. I have no screen protector, I have tried soft resets to try and sort out, but that doesn't work.

    Sorry Microsoft, I have used a windows phone since the Lumia 800 and I am about to abandon ship unless someone from Microsoft acknowledges and says a fix is coming.

    I have purchased an Android phone (DooGee) for 48 that simply works well, and I can answer calls on that. So I am not losing business now.

    One of the biggest companies in the world, and they can't make a phone I can answer calls on.

    Just a follow up, I disabled auto brightness, and the problem has indeed gone away. I've lost the auto-light sensing, which gives me a pretty bright screen if I have to turn it on in the middle of the night, but that's a small price to have the screen responsive when needed.

    Did you try using Double Tap To Wake instead of the power button to wake up the phone? Does it give same effect?
    I use DTTW instead of the button, along with auto brightness and never had any problems...

    For me turn off "hey Cortana" seen to solve the issue. It looks like 950 can't handle all these the sametime, DTTW, iris, power button, hey Cortana and glace screen.

    I followed advice given above to turn off the auto brightness. This solved the problem instantly, and it hasn't returned. Yes, you may end up with a bright screen in the middle of the night if you check your phone, but a small price to pay to have this resolved. I have to give beman39 credit, he steered me in the right direction.

    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.
