Hello,

ever since I got my X I noticed a weird bleeding/color blob issue in the top left corner on the red wave (SG default wallpaper) only.

It only shows up when the frosted black overlay is visible (reachability or faceID unlock) and is only really visible in the dark with brightness turned down.

The strange thing is it only shows up on the red/blue wave live wallpaper (I tried the others and can‘t see it). If it‘s an issue with the specific wallpaper then surely someone else has the issue too?

I took a picture with a friends phone, you should be able to see the distortion in the top left corner of the screen (looks like a shadow in the pic). It looks like a color bomb exploded underneath the screen (when reachability ends the texture of the distortion also shifts a bit).

Looks like OLED burnin, an unfortunately common problem with OLED. Try to get it replaced at an Apple store?

The thing is it only shows up with reachability. It does not show up in normal use cases. I‘ll contact Apple support though.

Can't seem to duplicate it on mine, what wallpaper are you using?

The red/blue wave wallpaper you can also see on the space gray box. Its only visible in the dark with brightness turned down and in reachability or when FaceID has the unlock overlay.

At the first glance appears like a screen burn. But you are saying you see it only on reachability mode. Whatever it may be, Apple should sort it out for you. No issues on mine.

Yea I see it on mine as well, but only with this one wallpaper. It almost felt like the screen brightness in that area also changes. I've tried the cloudy red/blue wallpaper and couldn't duplicate the effect.

So this could be an issue with the wallpaper itself? I hope it is, the nearest Apple store is pretty far away.

Can more people confirm? The support chat wants me to bring it in for an inspection. I‘d rather not waste my time if this is related to a live wallpaper issue.

I think it has to do with a specific color gamut, I downloaded the non-live wallpaper here and was able to duplicate the issue:

This no other shade of red is affected. Another funny thing is you can see the wallpaper change a little bit when you activate the reachability. I don't use reachability so I never noticed it before.

It’s not burn in.

Some of the stock wallpapers create blobs when there is a transparency.

Change the wallpaper and it goes away.

Can I forward your picture to the support chat? That way they see that it could very well be an issue with the wallpaper (and potentially fix it).

Sure I want this issue fixed as well, even though I never used this wallpaper or reachability.

They sent me a case link to upload images to. In addition the support rep said the more reports/images/info they get via the feedback site the better. So if you‘re feeling bored some time you might aswell upload a few snaps too.

I‘ll upload better pictures later today via my old iP7, that one has better low light images than my friends phone.

They also scheduled a phone call for some time next week to tell me about engineerings findings. I‘ll report back then. I hope they can do something about the issue, it‘s my favorite wallpaper.

Dude, just chill out. It must be something to do with the display calibration as this only appears on some devices, such as mine. If you take a screen shot and have the same brightness and display conditions, it’ll still be there. If you zoom in, it’ll enlarge. So it’s somethjng to do with the color not being able to be accurately represented on the display.

It’s not bleeding. It’s not burn-in. It’s banding. Google oled and banding. Nothing to worry about. If you don’t like it, change the wallpaper.

there is no defect, it's the wallpaper. reachability mode puts a (gaussian?) blur filter on the background and another very dark but slightly transparent layer over it. as good as the iPhone screen is, each of these operations require more gradient shades than are available and the display starts to 'flatten' the gradient where it can't display enough discrete shades.
There's really nothing to replace and the system is working as it's supposed to, you will see variations of this effect with any background with very bright colours.
