iPhone 12 OLED Screen Issue

I accidentally discovered something weird with the greenish backlight .... when I make a test (you can use setting > general > software updates ) and try to turn your phone into different angle, flip down and up the toward you, then you will see the flickering backlight appear every time you move your phone (only 100% will show pure black) ..... i think it have also related to the sensor movement ....

its been improved with 14.3 but still flickering , not as bad as before but the issue it’s still there. If they can’t fix it via software must be hardware related. I’m going to try to exchange mine tomorrow.

i choose the black background from iphone 12pro, then i took a screenshot, cut the middle to get a pure black image. if i open this on the iphone 12pro with a brightness under 50% it starts to glow green,

with 100% brightness its really black and you see nothing.

Lol... welcome to our issues!!! Every iPhone 12, pro, pro max has this issue. It might be hardware related, look at the iPhone 11 display recall, or it might be software. We shall see in the next few months.

I did. My first 12 PM did exactly what you are describing but my second does not. It only shows some flickering around 10% of brightness. I am returning my second one because of the yellow or warmer whites.

It does but it’s definitely less visible. The first unit would flash a lot more and it had that annoying green tint, this one doesn’t. The glow is still there in pitch black room when watching the famous “12 hours of black screen video”, but it’s more subtle.

Returning it for the third time would be a waste of time as the risk to get an even worse display is high! I really don’t know how they’ll manage to address this problem and if we ever see the light with a sw update. So disappointed in Apple this time. Sounds like they rushed the production of the entire 12 lineup due to the pandemic and made a utter disaster.

Black pixels being lit up instead staying turned off.

Also upon doing more tests with the HDR local dimming video, although there is flickering when the phone is in SDR mode (low power mode), there isn’t flickering on YouTube.com. The flickering only occurred in the app for me.

I also disagree that this is a placebo. As I mentioned earlier, when my screen of my old phone was around 50%, whenever I interacted with the screen, the screen flickered a green tint and went away when the screen becomes static again.

However, although there is still flickering in the YouTube app, the flickering shown in apps with black backgrounds on my first phone is no longer there for my new phone (at any brightness levels).

Initially when I first got the phone, I told my friend about the flickering issue and he was unable to reproduce it. I also thought he just wasn’t doing the proper tests, ends up there are just better phones and phones that suffer more from this issue.

If this helps, my second iPhone 12 Pro build week 49 has no flickering at boot at all. My first one had very visible flickering at boot up.

but when I watch a black video or a black image on my second iPhone 12 Pro I see the Green glowing

ill send it back and already ordered a new, maybe the last one.

Agreed. Just talked to Apple Support on the phone. At first she was not aware of the issue. After explaining a bit more what the problem is, she found additional info. She confirmed they are aware of the issue and are still investigating. Basically there will be a software fix or a repair program. They would not swap the device for now because it would be a waste if the problem indeed would be software. My mind is at ease. I’ll be enjoying this device and will wait for a solution.

Yes I saw that video today and zollotech mentioned that the issue with the pixels not turning black was fixed in beta 4.4, but apparently its not fixed according to others on this page.

I've never experienced the green tint or my display being too yellow and I think the issue with the pixels not turning all black is indeed an software issue.

hope it gets fixed soon..

So I have been doing some research on imei numbers and the first 4 numbers give us some info about the product, if there are different version or revisions of the iPhone, my 3 affected iPhones all started with 3530 and the 4th one I am going to get starts with 3595 which is either a revised version or a different version, I just hope it is revised to correct the screen.

Final Update,

Returned my 4th replacement. It had this blinking issue. Third one was yellow as crazy! 4th had beautiful screen - so much cooler & perfectly displaying true tone mode. But i couldn’t stand this blinking issue. I believe we all are entitled to same display quality if we have paid the same amount. Finally got my refund. Bought a Pixel4a, now waiting for iphone 13.

disappointed, had ordered mine first on 25th october, had switched from android (onePlus). I loved Apple’s UI, so would jump back later.

plus lesson learnt-

1) Never buy phone at launch, let 2-3 months pass, keep an eye on issues and then buy.

Me too G9N

The display is perfect with grey uniformity until I got below 30%

I get grey glow at startup (Last second after true tone kicks in)

I also get flicker with black background that is hardly to spot

I think it is a mix of software and hardware

It surely can be worked with software specially the grey uniformity the display should not go such low brightness

As for the glow it can display true black so the gamma values should be redone
