iPhone X Smudges on iPhone X display

Hey everyone - don't feel like taking a picture of my screen, but I can confirm that with this wallpaper specifically, on the lowest brightness setting, and any kind of overlay present, that the high contrast red in the top left of the wallpaper blotches out in the same spot everyone has been posting.

Someone on reddit posted a picture of their screen a few days after launch, and it uniformly fits with the exact same blotch I have, and the one OP posted here. If you compare this wallpaper in "live" mode, versus "still" where it zooms it out a bit, you can see the blotches change size in relation to where that high-contrast red is positioned.

I decided to further test this myself to confirm that I didn't have a defective screen, and rotated the wallpaper so that high-contrast red spot was on the bottom, and low and behold, when the screen is at the lowest brightness with an overlay over it, the blotch was on the bottom, and the top left was completely normal!

TLDR: It's very likely due to the high saturation of that part of the wallpaper when an overlay of any sort is over it.

Edit: It will likely happen with similarly highly saturated elements of an image when a blur is introduced over it.

TLDR: It's very literally just this wallpaper, and specifically whatever the value of the highest red blotches out when in low brightness and an overlay of any sort is over it.

So what’s your conclusion about this ? Sorry but my English isn’t good and I aint got ur point in the previous post.
Common hardware defect
Common software bug
Or rare hardware defect ?

My conclusion is that it's a mix of the way iOS's transparency overlays' render on top of extremely saturated color values in an image, resulting in the OLED not being able to effectively display the accurate luminosity when brightness is extremely low in a dark room.

I would say this is pretty much normal with the way OLED's work. Given that the "smudge" is only visible in certain lighting conditions + min. brightness and specific to the image you're looking at, I'm not qualified to say if this could be fixed through software, but it's definitely not a hardware "defect."

What about the fact that if u turn off and then on the phone this effect in the same condition as before isn’t here anymore? In my case all had been fine for 4 hours of use then they had beeen back there again.

In the case of my testing I mentioned above, restarting/resetting has no effect, nor does it make a difference.

If I turn my brightness the lowest level, stand in a dark room, and have the passcode/PIN screen overlay come up over the red/blue live wallpaper, it will ALWAYS show the blotch in the top left over the red. And apart of my testing included rotating the image (NOT holding my phone upside down, but so the top left red was then in the bottom right) and to no surprise, the bottom right then had the blotch, proving it was the image, not the screen.

However, if you're experiencing something outside of those conditions I mentioned above (that other people have also been able to verify similar results) that goes away with a restart, do take it to the Apple Store.
 
I believe this might be a software issue. I turned off true tone and this issue was gone.

They said it’s a “defect” so that’s why they sent a replacement
 
I have the same issue as the original poster. I'm glad to see I'm not alone and that it's software related.

Replace or not ?
