iPhone 6: Apparent backlight uniformity issue

My new Verizon iPhone 6 64GB exhibits a darker region on the top 1/8th of the display. It is most evident when displaying a white background. It is difficult to tell whether it's a chromaticity issue (AMLCD issue), a luminance uniformity problem (backlight), or something else all together.


Anyone else notice this effect on their new phone?

iPhone 6, iOS 8, Verizon 64GB

Same issue 😟 I just found out my iPhone 6 128gb had slightly black shadow on top left corner. It's been one year plus since I bought the phone and it has been working perfectly fine until just now I spotted the black shadow. I did some research on the problem but couldn't found an exact answer for it. Anyone has an answer for it? I might send it to apple service center to check, I am wondering if the warranty is over, will they replace it with FOC? since I believe is their QC problem. Anyone is over warranty but get FOC replacement? and what if I choose not to make the replacement, will the black shadow spreads?


Apologise for my bad english.

I Have the same problem. It started as being brighter on yhe top part if the screen and then couple of months later, i have a white line and now bleed on top of my screen. I hope they are going to replace this free of charge because this has been a problem since then. It is a hardware defect. My phone is free of scratch and dent and no broken screen...

I got my iPhone 6S Plus 64GB space gray (running iOS 9.1) a couple of weeks ago and it has two screen issues:


the first one is non-uniform backlight, which is very well depicted on a photo that someone else took:


http://forums.macrumors.com/attachments/pasted_image_10_3_15__4_10_pm-png.589387 /


Regarding this photo, mine has the exact same problem, with addition that there are 10, not 9 such stripes - one is also at the position of battery indicator, which is also seen on this photo, but the user obviously forgot to mark it with an arrow.


The problem is very annoying on white backgrounds, but also noticable on some others too, e.g. violet. Resetting the phone, turning the white point off, increasing screen illumination or reducing transparency don't help noticeably, so it's obviously a hardware problem. I'm also quite sure that future iOS upgrades won't help.


I have also inspected the iPhone 6S space gray of a friend of mine and it has the same backlight uniformity issue along the top side of the screen, perhaps just a bit less pronounced.


Considering the length of this thread (and also other quite numerous threads that I found on the Internet regarding this issue) and based on my own experience, I can say with fair confidence that the vast majority of iPhones (6 and 6S as well, both regular and Plus sized) are affected by it. It's not random, it's systematic. I'm also quite sure that it should be quite hard to find the iPhone 6/6S with perfect display, by "perfect" meaning that there are no such glitches, very obvious and very disturbing even to my non perfect vision.


The second problem with the screen is very slight (but also quite annoying once you notice it) blue tint along the screen vertical edges.


I still have my old iPhone 4 which has a perfect display as far as I can see.



Best reagrds,


Albert

I'm on my 2nd Iphone 6s+ Gold 16gb. They both have had this issue with the black shadowing up at the top right of the screen near the battery icon. After reading through all these posts...I'm pretty much resigned to the fate that this is a screen lottery where you may get 1 perfect screen out of several replacements. Smh. I thought Apple was know for meticulous perfection, but I'd be dead wrong.

General recall of iPhones 6 and 6S would be appropriate.


I don't have the will nor time to play a replacement lottery.


It is beyond rude of Apple to expect of their customers to play that insulting game, considering a fair price was paid.


I'm very insulted by this disgraceful scandal, to put it mildly.


Next time when I'll be buying an Apple product - if I'm ever gonna buy one again at all - I'll unpack it inside the store and keep unpacking them until I find the one with a functional screen. All sorts of tints, shadows and smudges is not a functional screen by my criteria.

I ended up going back to Sprint to exchange my 2nd Gold iPhone 6s Plus that had this issue. After the employee made a call to the "higher ups"...he took out their entire stock of phones and started opening them up one by one to get one that was free of this screen issue. First phone he opened up, had the screen issue worse then the one I was returning. The second one he opened up, FINALLY, a screen that did NOT have this issue. It only took 4 phones!!! To get one without a bad screen.


So, I ended up leaving the store and was happy...until I got home and tried to press the Vol down button. It was stuck in! The Vol down button was jammed into the unit and didn't click the way it was supposed to. I really can't beleive how terrible the Quality Control is at Apple. To go through 4 phones and still not get one without defects, is unreal.


At that point, I decided I was done with Apple. I returned the phone and got the Samsung Galaxy S6 Edge+ and the first phone..FLAWLESS. Apple will never get my money again until they use OLED screens where backlight issues will never be a problem AND they revamp their Quality Control process. 4 phones all defective is something no one should ever experience. This issue should be known as a recall and be fixed immediately!

The fact that this issue is worldwide upsets me the most.

I live in The Netherlands and I'm on my third replacement and this screen is still no better.

My first screen had slight darkening around the edges but it definitely wasn't noticable but I

had to replace the screen because I had dead pixels. One of the reasons why this issue is still not resolved is

that unlike us, most of the people "don't see it". I even got sent away at the Genius Bar because 4 employees didn't notice the

backlight issues. I tried telling them that it's hard to notice it under the vibrant lights of the Apple Store. On a side note, my iPhone came with an misaligned front camera and a loose sound button. Apple needs to step their quality control game up.

Hi, I deal with exactly same problem, that dark color around the status bar. I bought my phone 3 days ago from orange Romania, before that I had a word with some friends of mine and they told my about all this problems that iphone does have, i do not belive them - but now...I can't say a thing. Paying a lot of money to this product and have this type of issues, is driving my crazy guys...
