I use my X in a pitch black room on the lowest brightness setting a lot. I never notice any flickering. All I notice is a vastly better quality screen compared with every other prior iPhone device.

Take another smartphone, and point the camera at yours. Try the X on max brightness and at 10%. You should see some flicker in what the camera sees at 10% but not 100%. You may not be bothered by it, mind you. I just tend towards dry/sensitive eyes and don't want to aggravate it.

  I have very sensitive eyes with classic night blindness and an iPhone X. I don't think I've noticed any problems with headaches or eye strain. Did you notice them after usage or is it just a hypothetical outcome? Does the auto brightness control feature mitigate the problem or push it front end center? I'm curious as I also do not want to aggregate my situation.

    I didn't use an X long enough. I didn't want to chance it. So, hypothetical. However, you can use reduce white point and a higher brightness at night to avoid the flicker. Can be triggered with accessibility shortcut.

      Cool, I will check out that setting and keep this in mind for future displays!

  I also have really dry eyes pretty much year round (and I'm in Denver which unfortunately makes that worse!) and it's still no issue. I have seen the videos (especially review videos) where the flicker on the camera is present from another camera, but I haven't noticed any eye strain or any problems with this device. If anything, I'm using it more than my previous ones because reading text on it is so enjoyable with the better screen.

    Oh interesting. So, while this affects some people, it may not affect me. The main people affected are those who get headaches, would you say? Maybe I should reconsider.

  Your eyes become less sensitive to flickering in low light. That's how movie theaters could work at 24fps. That's not to say no one can be bothered by it. But it's much less likely to bother anyone. I have sensitive eyes and tend to notice flickering at anything less than ~70hz. My Xs hasn't bothered me and I tend to use very low brightness even in well lit env.

    Traditionally, movie theaters showed each analog film frame two or three times, so the flicker would be 48Hz or 72Hz, not 24Hz. 24Hz flicker is very obvious and annoying to everybody. Digital projectors might sample-and-hold like LCD displays and therefore have no flicker despite the low framerate.
