    Phone is working great so far, like it - except for one annoying thing.

    I have a black and white skyline as my wallpaper. After unlocking the phone in a brightly lit area, a few seconds later, the wallpaper picture dims.

    If I am in regularly lit area, the dimming doesn't happen. If I change the picture to one of the crazy bright colour ones under wallpaper-stills any in the third row, they don't dim. If I change the wallpaper to wallpaper-live, the third picture then it dims. If I turn off auto brightness no dimming occurs.

    I'm using the same picture on an iPad Pro no dimming issue after unlocking.

    Anyone else seeing this? Super annoying me.

    No one else? I’ve noticed that with a brighter wallpaper there is a really slight dimming if icons when unlocking in bright light, but it’s not as noticeable as when using a darker-greyis coloured photo.

    I’ve noticed it. But doesn’t bother me that much.

    Only time I see dimming is going from a very bright conditions to less bright. Mine is also set on auto.

    I've noticed the lock screen wallpaper will start off a darker shade than it usually is for a split second before transitioning to its normal contrast. If that's what you mean.

    My iPad has been doing this. I think it might be intensional as a visual effect. My wallpaper has lots of dark and bright points and the effect does look kind of cool, as only parts of the image darken while other parts stay bright.

    Thanks everyone for your replies. I stopped in an AppleStore between appointments, and side-by-side-ed mine with a demo 8 plus. There's something not acting right with mine. The store person was curious about it as well. I didn't have my box etc with me to exchange it, but I will try exchanging. It's quite a dramatic change three seconds after unlocking.

    True tone? Or night shift accidently enabled?

    My 7 does this if I have auto brightness on. So I leave it off as it was kind of annoying.

    Took it back, they had a look at it and clearly something was wrong with it. Exchanged for a new one. After spending some time with the new one: IT DOES IT TOO! So annoying and a colossal waste of time. So either I get used to it, or take it back and figure something else out. Not impressed!

    I backed up, DFU restored as new, then tested it and it's still doing it. So my guess is they all do it, or I just have the worst luck. I guess I'll see if I can live with it, or return it and get an altogether different phone.

    Not sure my situation is the same or not. I notice that when I am in bright light conditions, my phone will seemingly drop a brightness level on its own. It is random, but noticeable. It also happened on my 7 Plus and regular 7. I do not keep my phone on auto-brightness. It is almost always when my phone is on max brightness in sunlight or a well lit area and it is frustrating because those are the times I want my phone to be as bright as can be. No clue why it (they) do this.

    I came from a 7 Plus as well. I had not noticed anything similar to what I’m seeing on the 8 Plus on the 7 Plus. This issue is really noticeable. Unlock in a bright environment, and three seconds after there’s a drop in brightness / dimming that happens like clockwork. It’s not a gradual drop, more a dramatic change. Since the second 8 Plus is also displaying this, I’m hopeful it will eventually get sorted out software wise. Interestingly, I have noticed that disabling auto brightness seems to stop the problem.

    I will have to pay particular attention tomorrow to see if I can recreate the issue and under which specific parameters. I do not ever use auto-brightness so I cannot speak to that. But I would think that if auto-brightness is disabled, then fluctuation in brightness would not occur. But that is the case with mine. Very odd. I will test it out and report back.

    Thanks ARizz44. Bright sunlight really shows it, but any bright light. It’s not just the wallpaper. If you just hit the power button, and don’t unlock, then wait three seconds. Have auto brightness on.

    Yup I notice that on my 8plus. You mentioned you tried it in the store too. Were you able to replicate it there?
    It's almost like a slight drop in brightness a couple of seconds after the screen wakes up. It does not look to be the result of auto brightness fading and adjusting. I believe if I disable auto brightness in the accessibility settings, then the behavior stops.

    It will also happen in the home screen if you unlock it fast enough.

    Hi Kevin. I tried in the store, but I wasn't able to replicate it on the demo. I should have checked the settings on the demo phone: disabling auto brightness seems to stop it. Not sure if the demo phones have that off perhaps? Hopefully it's a software issue that will get sorted out.

    I have the default iPhone 8 beach shore wallpaper. When I try to reproduce the issue on full brightness, I dont see the issue. Maybe the brightness in the stores were all on full brightness.

    Why in the world would you exchange your phone? This is not a hardware issue. My phone is doing this as well, but only when I change lighting conditions. I am sure there will be a software fix for this.

    I am surprised that there are not many complaints on this issue compared to other issues. Is it because it’s not as noticeable? Any idea if this fix is included in 11.1 beta?

    I’ve noticed this as well especially in the office at work. I don’t really notice it at home.

    Yeah same for me. yesterday I went to the apple store. I noticed that the display units don't have auto brightness set. I turned on auto brightness in accessibility and was able to see the issue on their display models. Hopefully Apple can see this issue and get it resolved by software update.

    I exchanged it because it’s driving me nuts. My iPhone 7 Plus on iOS 11 wasn’t demonstrating the same issue. I also tried a demo phone in store, and it didn’t seem to “drop” dim on unlocking. Kevin, I didn’t think to check the auto brightness setting on the in store demo at the time. Had I done that, I would have saved myself the inconvenience of the return. I’m hoping this will be fixed in an upcoming iOS update.

    Also I posted this thread, and it didn’t seem anyone else was seeing the issue. Figured maybe something was wrong with the sensor.

    So, what did you do after replacement phone did the same? Did you exchange it once again or what?: )
