iPhone 6: Apparent backlight uniformity issue

So I just compared my iPhone 6 to every iPhone 6 in a local Apple Store. What I found was that the screen on each and every one looked different, but all of them had a darker band at the top of the screen, under the receiver. And, although they all looked different, the screen on each had obvious hot and cool spots when showing a white image - they were just located on different parts of the screen – giving each a mottled, uneven appearance. Nearly all of the screens on the phones in the store overall trended towards a blueish hue, whereas mine overall is trending yellowish in comparison, but I remember mine looking more blue compared to others at first, so I’m not sure if the phones on display are newer and the screen becomes more yellow over time (or if there’s a setting making them look more blueish). Something I found interesting was that, when an employee came over to see what I was doing and I showed her the darker areas on the screens, even though she saw them immediately she said she had never noticed them before.

I left the store feeling both better and worse. Better in the sense that I feel less that something is wrong with my phone in particular – because there’s apparently something wrong with many (all?) of them - and feel more confident that getting a replacement will likely not net me a “perfect” screen. I feel worse in that once I’m back home without other iPhones to compare mine to, I can’t stop noticing how bad the screen looks when reading with a white background and miss the perfectly uniform and white OLED screens of my past two Nokias. But, all in all I like the iPhone better, so such is life I guess.

Guys I think I have a theory why they sent us yellowish screen in comparison to store iPhones (i checked it several times and I always got a yellow one in comparison to store sample). Maybe all phones are not uniform and have yellowish areas on random part of the screen and one on the top so they set a screen temperature toward yellow in order to mask these defects a but (but it is still visible). Just a theory.

I have the same issue on my iPhone 6 (dark patch near battery, slight dim band at top and very slight yellowing towards top of screen), mine is C39, week 45, but I have also just started to notice in the last couple of days that there is a very slight darker vertical band running down the length of the screen- it is not visible face on, but only when viewing at an angle- as per one of the previous posters, it temporarily goes away if you massage the screen in that area! It seems to me that they've packed everything in so tight in the iPhone 6 that the slightest pressure (and maybe heat?) from motherboard/ electronics etc is causing these uneven backlighting issues....

The first iPhone 6 (DNQ) got had these shadows on both the top right and bottom left corners.

The second one (also DNQ) is not as bad as the first, but still very annoying, as I see shadows from top to bottom on left and right sides:

I am really disappointed about this product. None of my Apple devices ever had such a display problem. Not even a Dell computer has annoying shadows like that.

I have just the same problem on this version. :(

My iPhone 64G Silver manufactured at Jan 2015 has this screen issue also, very disappoint about such common defect on Apple product.

Someone posted a picture of half their screen being blue, the other half yellow. Well apple finally just said score it and replaced my 128GB 6 with an iPhone 6 PLUS 64GB. First one had stuck pixels and the dreaded dark corners, plus the bottom half was a whole 50% darker. Exchanged. New one is even in backlighting, but the left side is **** yellow. I have discovered this is heat related. The processor is on the right side. The heat makes the screen blue, where as the left side has no processor to warm it. Applying slight heat to the left side evens out the color significantly but reverts back to the normal yellow after a few minutes away from heat. I'm hoping after a while of heating the left side it'll permanently remove the yellow tint, but Im not very optimistic about it. Otherwise its very distracting and is going to be exchanged first chance i get. Very very disappointed.

My iPhone 6 discoloration across the center of the screen, yes it was there when I changed my screen protector but it was not there when I got the phone? It came out of the box the screen protector went on followed by the case! My phone space gray black case my fiences phone is fine.

I can't believe this is still going on! I'm on my 4th iPhone 6. F73 unit - and still has dark patches at top and down side.

I am heartbroken by the fact that Apple doesn't seem to be doing anything about this. I don't have the energy to go for another swap, and I can't stomach paying such a high price for a device and having to settle for crap.

Its a common problem with iphone. I have had the iphone 6 128G for three months, and I'm dissatisfied to say the least.

iPhone 6 64GB Screen....

My iPhone 6 64GB had discoloration in the center of the screen so I was going to return it! But now the screen is loose in both the bottom left and right hand corner's. This iPhone was taken out of the box put into the case with the screen protector it look brand-new like the day I bought it!

SO i had the same issue dark side on the top of the screen right corner i went to aplle, they raplced the whole screen. It looked better i went home i stared at it for like a minute and i noticed that i had a dark spot on the top but this time was at the center. so i wen i the apple store and they gave me a new phone since the issie didnt get fixed with the rella ed iphone. And now i still have the same issue but its on the top right corner and its ******* annoying WILL APPLE EVER FIX THIS PROBLEM ?!.

The problem I have with mine is that the right half of my screen goes very dim and i just upgraded to 8.4 but no luck.

So I sent my iPhone 6 in to fix the FaceTime camera (again 4th time) and they sent me back a replacement. This phone has a dimmer upper right hand quadrant. And the lower left quad is a little yellow and dirty looking. This is my 6th total iPhone 6. 5/6 have had screen defects just like the ones on this forum. I thought they might have the problem sorted out by now but they don't. I checked my serial number and it's made in July 2015. Very disappointed with this generation. My last phone actually had the best screen out of the bunch but I needed to get the camera replaced because I want to be able to sell my phone next year and have 8.4.1 on it since it runs the best on the iPhone 6. This one has a new problem. The lower right part of the front panel clicks when I press on it and its loose. This just *****.

I replaced my iPhone 6 five times. Every phones had backlight issue. Yellow-grey tints. Now I have one with white stripe on bottom of display.

Dear Apple, are you joking or what???? This is premium product??
