    I'm afraid it's hardly a software issue as my screen has the top darker than the bottom - so top - down rather than left - right. Seems more like a fault in the glass or the filter layer that has been applied to it. If it were a software issue all screens should probably misbehave in a similar fashion.

    Overall I'm not really happy with the phone. The screen darker on top, heats up while browsing the web - haven't even tried gaming on it yet - battery life is not really good and the weight combined with the excess heat makes it rather uncomfortable to hold for longer periods.

    :(

    If you rotate your phone slightly, you will notice that the whites become colder (bluish) at a pretty small angle.
    The thing you notice - I also have it but - may be a byproduct of this.

    The "black bleeding" is most probably a unrelated, software issue that will be fixed by Nokia in the future.

    I wouldn't ask for a swap, mainly because I don't know how long it would take.

    I wish it was that simple but no. The hue shift when looking at the screen from an angle is a different issue. The brightness / darkness difference between top and bottom parts of the screen visible on every solid color except black. For example, a solid gray color appears as having a slight gradient running from top down - in fact that's what I first thought it was. And it's the same no matter which angel you look at the screen from.

    It wouldn't be the first time issues like these pop up when a device is moved into global mass manufacturing - the requirements for quality control get lowered in order to keep the price down and max out the production rate. At the time the Samsung GS2 came out I went through four different units - each of them had different displays - ranging from perfect to way too dark and the ones with wave like effect in brightness or uneven colors.

    Sucks to get a 'faulty' one.

    I do hope these "faults" are a minority. Looks like I'll need to check the device out when I buy in store to make sure its good.

    The only thing I would love to know, now, is who makes our oled display.

    I'll probably keep the phone as this is the only issue in having.

    Some people are reporting very hot phones, tap/swipe problems and very poor battery.

    Thankfully I don't seem to have any of those (battery isn't great but it gets me through the day)

    So although I see my problem I think I could probably live with it as its only really noticeable on greyish colours.

    I don't want to swap it for one that is similar or worse.

    So you're happy to spend nearly 500 for a phone that not up to standards?

    Which issue did you have? Darker pinkish hue at the top when on white screens?

    I have decided to send the phone back to amazon.fr and re-ordered a new one through phones 4 u - got the phone for the similar price I paid with amazon plus I get the added bonus of a charge plate included in the box and the wireless bundle worth around 150 (made the decision a lot easier).

    I'll report back next week when I have the new phone if it has a similar screen issue (hopefully not)

    I have the EXACT same issue. The boot screens are perfectly black, but as soon as it loads the start screen, I have a washed black (almost %40-%50 gray) at the bottom, fading gradually to the top.

    So I have 2 issues right now: Purple tint AND $hitty blacks. Speaking of the first one, that color profile "fix" merely makes it tolerable, it's not a perfect solution no matter how fine you tune the settings.

    I made a video showing the issue. Compare the dead-black boot screens versus the blacks in notification center.



    Two pics as well:

    About the purple hue, I have it on the top of my display. First one is a white PNG (255,255,255) and the second is %50 gray (128,128,128). It's visible on the right side of the images:

    Ok I noticed something:

    Last night I hard resetted my phone and the black issue disappeared, blacks are perfectly black. BUT as soon as I update the diaplay app it gets screwed again. So I did another hard reset, set the updates to manual.

    However, this does NOT solve the purple tint.

    I have this gradient on gray colors ever so slightly. It's barely visible so I think I will live with it. I see it if I'm looking for it. Not sure I want to exchange my phone and risk getting a new one that is worse or the same. I have no other issues.

    I can hardly capture it on a photo so I won't bother changing it no. As I said it's only sliiiightly visible. This is unfortunately common on Nokia displays as back in the Lumia 800 days I had to change my phone three times to get one that had a uniform screen. Sorry to see their technology hasn't improved.

    Same here - I feel it is mostly visible on grey backgrounds of some sort, i.e. the keyboard area or when making a call. blacks are perfect on mine, greys uneven and ... quite crap to be honest with you.

    Yes it only shows up on grays such as on the OS screens for calls, setting alarm time etc. My whites and blacks are perfectly fine and any other color. Can see it on the keyboard too very slightly if I'm looking for it. But the fact that I almost have to look for it and it's not very visible makes me afraid to even try to exchange it because I don't want to go through the possible hassle of switching several times like with my Lumia. I'll settle with the little I have as can be seen on the photo above.

    Same here, I guess. Although I have to say I'm pretty disappointed with the quality of the panel on the 930.

    Yeah same here. It still has the exact same problems the Lumia 800 had on its Amoled screen. One would think they had improved the technology by now.

    Try to uninstall the Nokia Display App by setting the date on your phone to the year 2300 and tapping on "display" this fixed the issue for me, at least the one I see in the second picture in your post :)

    The only thing I would love to know, now, is who makes our oled display.
    I do believe it is likely one of Samsung's AMOLED displays, possibly the same model or similar to that used on the Galaxy S4, it does appear to use the same Samsung Pentile subpixel layout and have similar characteristics, i'm fairly certain that Samsung have supplied just about all of Nokia's AMOLED panels over the past 3-4 years:
    [I cannot post links but look at page 3 of the gsmarena Lumia 930 review]

    An in depth look at the characteristics of the Samsung Galaxy S4 display by Erica of angeloftech website: [I cannot post links but look at Erica's "Galaxy S4 ALL YOU NEED TO KNOW: Part 2 (Displays)" video on Youtube, searching that exact text should get you to it.]

    Erica notes that each particular Samsung AMOLED panel tends to have varying qualities as far as image quality, accuracy and display uniformity goes also noted is how bad colors on many devices get when you drop brightness below a certain level (around 50%), many people came across this throughout Samsung's Android devices with AMOLED panels, and many apparently had success just swapping them for replacements until they were happy with what they got, or simply getting a refund and going elsewhere (which tended to be nowhere if you wanted android a few years back).

    edit: seems wpcentral is using a full name instead of what I thought I set as my username... don't suppose there's a way for me to change that?

    The pentile matrix on the lumia icon look pretty much the same as the 930 in that GSMarena review, found this magnification of the icon's pixels:
    13039853035_feebb236b7_o.jpg


    And here's that of the 930:
    nokia-lumia-930.jpg


    So I don't think they used a cheaper panel for the 930 than for the icon (which was a theory I recall reading somewhere)

    I should had known myself better. In the end the uneven uniformity of the screen got the best of me. Even though it was very little, knowing it was there I noticed it all the time and I did not like that at all. So today I took a chance and went to replace my phone with a new one. And bam now I have a 930 that has a perfectly uniform screen. So now I'm a happy camper.
