iPhone 12 OLED Screen Issue

After refuse by Genuis Bar (replace a device, because they checked evertyhing is okay nothing wrong with the screen - they denided to get the phone into a dark place to test.... and repeated the same sentance ... the system show your phone screen is perfect has no defect ...)

I talked again to the Apple Support online and requested Mail-in Repair to the Apple Repair Center. So will see how it will be the result after the diagnosis... :)

They were trying their best to convince me it was software-related but I DEMANDED a replacement and asked them to test the screen in the dark. I told them they can lie as much as they want but if compared to an old iPhone OLED (11 Pro/ Xs/X) the defect was blatant and irrefutable. That’s how I “forced” them to service my phone and they actually listened and did it.

However I didn’t solve the problem at all but at least this one has a less visible flickering. 🤣

There are two possibilities. Either Software or Hardware. In Hardware, it may be a batch of OLED defective screen was installed in that Batch Production of iPhones. They can trace it by production number to isolate the case to compare with another batch that doesn't have the same symptoms.

On the software side, maybe it is a bug that the developer missed a syntax or wrong formula. This can be isolated or can be fixed by getting a sample with the same problem. Then rewrite a code that can solve that issue and it will be out as a "software update" with another build of codes.

That is very infographic thanks

but you can't compaire oled to LCD

as it will of course appear tinted specially to green as the green subpixels are already twice as much as the other two

problem is with the new iphones that they are tinted to show more which have a great hit on the color reproduction so they appear tinted

problem is that apple does not give the option to personally calibrate it (the color filter is a hue slider you can't precisely edit the display colors)

I decided to sell my 12 Pro Max as I can't refund or replace

Apple will not fix that with a software update the display is calibrated at the factory you can't recalibrate it as other good displays will be harmed

so sad that it became a lottery now when you buy a new iphone you may get a significantly worse display than others what's new with this year that the affected users are much more.

I would wait to see if apple will provide any solution until at least mid january. If not, I would definitely try harder to return it or to get it replaced again with apple.

if they don’t let you, Only then I would sell and lose $150 instead of looking at the ugly green glow.

I talked to an Apple specialist the other day and explain the problem. I even copied the link from this forum and sent it to him. He said that Apple was aware of the problem and that the issue was going to be resolved in the next software update. If not Apple was going to solve the issue another way. I think Apple is a decent company with good costumer service (at least here the USA) one example for me is that a year ago I bought some AirPods Pro for Christmas, after a while they started to make a little rattling noise. I contacted Apple and they sent me a brand new replacement for free, for me that speaks a lot about a company. That has been my personal experience with apple. Hopefully they solve the issue via software update or send us new iPhones.

I also have this problem related to this strange illumination along the volume bar but I think it is software, in fact starting the same video through safari and not through the youtube app the problem does not arise .. but I have a very yellow tint and a green tint in dark environments .. I am waiting for a replacement of the device hoping it will be resolved

G0 is from USA. Here are my thoughts on the oled lottery. There are different factories G, C, F etc are the different factories which assemble the iPhones, the number or character that follows is the factory number as they are placed in different locations. Foxconn has a factory in USA too. The first 4 numbers of the imei are the model and there are different revisions for improvements, for example 4 of the iPhone minis i got had 3530 starting of imei which were all bad, later i got another one which was 3529 which was also not good, my current one i have 3595 which is leaps better than all that i have had before. Moving on, the production week could be a deciding factor here because different factories may have got notifications at different points in time about the screens being defective based on the complaints received and therefore it is important for us to double down on this to find already with the serial number and imei which one is already revised and having flawless displays. I hope all of this makes more sense now.

Yes, you are right. The 12 Pro Max is not perfect, like it should! The green-subpixels are still on (but very very low).

On the 12 Pro this is, let's say, 4 times stronger than on the iPhone 12 Pro Max.

Hi guys, i'm just written to Apple support. I was told that Apple knows this problem and they are working on a software solution. The fact that support reply to me that Apple knows the problem is a big step

It points more and more towards a software issue linked with the display firmware.

If it was hardware, the faulty display batches would have been identified in the supply chain and the newer batches wouldn't show the issue .

little edit , did u try to be in a pitch black room with zero light sources and check a black wallpaper for example in the photos app and moving brightness to be sure your mdel is perfect ? when u boot it in a pitch black room after a little time when the apple logo appears don't u see the gray screen for a few seconds then it snaps back to pure black...

Yes, I would recommend to return it and get a new one. It will not be worse than your current situation. I got it from the Apple store in Paris. So yes, ordered from apple.fr and picked up at the store.

I realized that the green tint only happens when I’m watching a movie/series. For example, when the Netflix N appears it is all full black but the N. But when the movie has a dark scene, the charger side of the iPhone 12 has that green light.

I’ve tested with full black pictures and that green light doesn’t appear 🤔 I really think it’s a software issue...

I guess that answers the hardware vs software question. From the looks of it, this is a hardware problem that they are unable to -FIX- and can only mitigate by having the software attempt to compensate.

I still think the issue is with the display controllers, not the displays themselves.
