iPhone 12 OLED Screen Issue

Hey, late to the party. Just discovered this issue with my Lock screen.

First photo is how it should look all the time, how it loked on X, and how it looks on 12 the first half-a-second upon waking.

The second photo is how it looks when the bug kicks in.

No settings, switch-offs, locks or unlocks affect this behavior.

In YouTube videos OLED works properly. But in any system app in Night Mode I can easily notice where the screen ends and the edge begins - there pixels aren't completely off.

So after ordered 5 Iphone 12 pro max , still waitinf for 3 refund, i kept one and still can return it, but IOS 14.5 dev beta soesn't fix the grey flicker i have ... btw thx to siri now i precisely say that the gray flicker on pitch black picture is happening only when brightness is below 55%... so weird.. but i think i'll keep it, cos to me it is software . otherwise when the phones were booting in a pitch black room the screen would have this flicker as soon as it boots, and it happens each boot after some time when the apple logo appears, wich means it is related to software.

The thing about perfect black during the boot is that the screen is working on max brightness level (on which issue doesn't occur). It is then, closer to the end of the boot process, being changed to a lower value set by user or a brightness sensor, followed by raised black/backlighted pixels glow, then you see a screen is uncapable of working properly.

Just updated my iPhone 12 Pro to 14.5 Public Beta 2 to see if the issue is fixed. Some bad news here - it isn't completely. Defect used to reproduce when most of the pixels needed to turn off (mostly black image). Now it reproduces in reverse - glow can be seen if most of the pixels are lit, e.g. open some photo in fullscreen and check black borders in total dark. Maybe it's only my phone, but I guess people got too excited and made premature conclusion that problem is gone.

Upd. Also, I've observed that in some "Local Dimming Test" videos on youtube app, left and right borders are blinking with grey glow once a second while the main video area is completely black.

same updated a few hours ago with dev beta, and yes boot sequence has been modify to not show the grey flicker , and viewing a black wallpaper in photos fullscreen doesnt reproduce the issue, but it's not perfect for example, go watch the video called local dimming HDR FALD on youtube , put it in landscape without zooming, and u'll see that the black borders on the side still flickers, and more important, each time u change brithgness on this video or similar one's i bet now i see the grey flicker for s split second when i exit control center, every time, before it was not happening 100% of the time..

so yeah great improvement but as apple stated in their patch notes, they tried to reduce the issue , not mitigate it, which makes me think maybe it is an hardware issue.. btw the yellow tint stay the same, still have the use the color picker in accessiblity to change the iphone hue to a more bluewish white,, which is 10 times more pleasing to the eye.

Try to play that youtube video in Safari, it’s perfectly black as it should. Overall almost all the green tint that appears when showing black content is disappearing in this 14.5 beta 2 (sometimes still noticeable a little). Hope the problem completely solved in final version.

i've tried again on TV app and it didn't reproduce but without bringing control center and turning the phone from one landscape to the other makes the screen flicker for a sec.. that's really weird ....

BUT now i know for sure it is software cos i added a movie on VLC, and in landcape moving brightness , changing landscape orientation , i wasn't able to reproduce the issue... so it's a strange bug that for sure will be fixed soon for those like me who still have it somtimes on particular occasions... the bad news is that i've ordered a 9th iphone 12 pro max this afternoon , to try to push my luch thinking maybe i'll get aunit that was produced in january or february.. and it's already on it's way.. so i'll keep you guys posted if the new one is better , 100% fixed out of the box, or worse than the one i have.

i wonder if apple will not send me an email like ' dear customer we noticed that you returned to us a ton of iphone 12 pro max , please be careful cos we will not accept future returns... like amazon does to some customers who have a retun rate to high...

i've phones apple this afternoon asking them if i was to order a new phones i had more chances that this issue would be fixed, but the person i had was so bad, i told her that apple aknownleged the issue on public beta 14.5 beta 2 notes, and she told me that they didn't know about this, that it must be me, i was so angry at one point that i hang up on her.... sometimes some employees are not fit and up to date with the info... nut usualy they are efficient i must say.

have a good week end.

i'm the crazy one who ordered each two weeks and returned 8 iphones already, i've ordered one 12 pro max 512 Blue again yesterday from apple to see if this time the production week. and serial do not start with F2, FZ or G0 ( 6 i got were F2, 1 G0 and one FZ )...

i'm gonna check if out of the box the issue has been mitigated from factory and then update it to public beta to see which one i have, cos i can still return the last one i got , but i didn't get who was made after 2021... expect the First one i preorder and got day one the 13th of november , most were week 51 or 52..

please keep giving feedback to apple that in video depending on the app using control center or not, switching from a landcape to another make the gray or green flicker still happening.

the more we give them feedback the more they'll know it's not entirely fixed. they told me that they do not monitor these forums at all... so dissapointed that Apple didnt made a statement for exigeant ppl like us who have good vision and notice this issue, i'm sorry but in France and Europe too this iphone is 1609 euros. it should'nt have any issue ( if it's hardware which i doubt a bit)

thx for your post @sagargrandhi

it's quite interesting that by restoring the Os, the problem dissapeard... cos officialy it has been fixed only on IOS public beta 145 beta 2... so that's why i was wondering, maybe i should try to order a graphite one to see.. i've placed 2 other orders... i guess that would make 11 iphone 12 pro max bought and returned... i think there is a possibilty that the Blue ones got the lesser quality displays...

does anyone else can tell us their color of iphone pro , max, mini and what problem u had like yeelow tinit, geen tint flicker or gray tint flicker? i have two iphone 12 pro max ( blue ) im' gonna try to erase all, content on one, and check if the issue is mitigated , cos it's still there on some videos.. and the issue can be reproduced but differently depending on the video app i used . but they have pretty much the same bahaviour, one who start with G0 have a lesser yellow tint.

12 pro graphite here.

I have the raised blacks / slight green tint issue.

I don’t think the chassy color has anything to do… I thing you are overthinking and also… the people that are ordering and returning phones like crazy…

I think we should wait for future iOS betas and share our progress. And that’s it.

I think that the problem is present in a high percentage of the phones but only some of us are perfectionist and see it.

So i've just got less than an hour ago My 9th and 10 th Iphone 12 pro max, bth starts with G0.. and end with D5C like all F2 and G0 Iphones 12 PM i've had since, i've entered their serial in the german website, and it's weird cos they are both coming from week 48... all the others 7 iphones from januray to today were from week 51 or 52... ( exept the first one who was preordered and i do not have data about this one ).

both have the same yellow tint and on 14.2 not even the latest version .. so i download the public beta profile and both are downloading 2 times 5 Gb of data for the update, i've noticed that one while booting both out of the box in pitch. black room have a stronger gray flicker on boot screen than the other one. so i think i already know the one i'll keep... but i'll test both of these a lot tonight and tomorow. i'll come back to see if i notice a change about the gray flicker which still appears on most video apps but each app behave differently with it... for TV app i've noticed the best way is to flip the phone in landscape on a paused black transistion watching a video.. for other apps like youtube the video is fine but not the black bars to the side who flickers a bit when changing brightness... it's a really strange bug. i'm really surprised i got older iphone 12 pro max from week 48 when all the other i got were made 2 or 3 weeks later... can they be refurbished ?? impossible to know i guess...

It's already been explained numerous times why some see green tint and why it bugs some like me. Here is link again for explanation basically poor QA quality control at factory!

"If your OCD is going to get triggered upon spotting the green tint once

in a while, while using the OnePlus Nord, this might seem like an issue

to you. For everyone else, the green tint is not visible while using the

phone regularly on a day to basis or while consuming content on the

display so this should not be a deal-breaker. If you are lucky, your

unit of the OnePlus Nord may not even have a tint if the display was

manufactured with precision.It’s not a problem per se, it’s just a bi-product of the complex manufacturing process."

Same here: s0nix are you able to read out the serial number of your display? See my reply above this one. Would be very interesting if Samsung finally managed to produce some flawless OLEDs for the 12 series.

This issue happens on all Apple devices - iPad , iPhone X, iPhone SE, iPhone 11 pro !! You can see on YouTube videos more prominently against dark videos ! You can get it replaced at the Apple Store , i am sure the new one will do thé same !!

I had the exact same issue! After taking my 12 Pro to the Apple Store three times they finally agreed to replace the display. However, even after the display replacement I still experience raised blacks at all brightness levels. Is it worth going back for a fourth time in hopes of replacing the entire device?
