iPhone 12 OLED Screen Issue

The problem with Lock screen "backlighting" ONLY appears when Do Not Disturb is active and ONLY depends on it.

Once Do Nit Disturb is off, there is my pitch-black Lock screen. Other settings including TrueTone, Brightness level, Auto-Brightness, Night Shift and Dark Mode in any combinations do not affect this.

I'd say that the bug is caused by Do Not Disturb Lock Screen sticky message, although the screen-tint is present even when the message is dismissed.

I have worked out a solution for screen flickering when brightness <90% on IOS black wallpaper or any video black edge.

go to settings - accessibility - Display&Text size and turn off the auto brightness.

I feel it’s a bug from IOS but there is a possibility that light sensor is not working properly.

See the image,the difference when auto brightness on and off

There’s also one person I saw on FB having the similar issue of having a green glow on phone’s screen who had his phone serviced at an AASP. He informed us that the service engineers in that AASP acknowledged the issue as a hardware defect and the whole device is now subject for replacement.

thanks , btw guys for those havinh the issue , i phone them again and they do not have much feedback from customers or enough to make an urgent patch , u need to call them explain the issue, i run a disagnostic, i've sent her the pictures taken in the dark , and this link, and she told me that for an issue to be resolved , they have to get by phone feedback from consumer to be able to make a cade number and the more theu have the more chances apple will do something quick . so please take 1 hour to contact them .

with PrakashParis , i dunno what to do , maybe you were lucky... and the thing is still there.. or do you advise me to return mine and buy a new one again ?

when did u bought it ? it was on apple.com i guess ? ( btw are u from France like me ? )

no i'm quite positive it is software, but they could have resolved the issue on the newer units , it is not hardware otherwise the gray flicker would appear at every level of brightness.

but apple could have tweak something to the most recent units to not having this issue...

but do not stress if u cannot send back your phone, but please as i said phone to apple and take time to explain the issue with a tech support , cos the more reports they'll have , the more apple will act on it. and unfortunately they do not monitor these threads like this one at all.

Guys Lets end the conversation here, it has been confirmed as a hardware issue by Apple itself. I was in touch with a YouTuber who had the same raised black and green tint issue.In his country which is India you cannot replace the device and only get it repaired.He sent his phone to two APPLE engineering teams.They identified this issue as a hardware issue and got his screen replaced.And now his screen is absolutely perfect!

Guys I don't know if the green tint problem is related to another problem I encountered .. having applied a dark background I saw the Clock application frame not black as it should be but gray, all off after applying a completely blue background magically the frame of the Clock app, as well as the black of the voice memo app, has turned black again as it should be .. i can't explain it but it's like there is a problem with dark backgrounds and pixels going crazy and they don't understand if they must go out or not

Update from my side:

I‘ve got my 7. iPhone 12 Pro this Friday with F17... SN and production week CW02 2021.

Still raised blacks, flickering when playing back movies with black content, but no green tint. The whitepoint and grey looks better to me than on my „old“ iPhone 12 Pro.

So in my opinion the raised blacks are definetly an software issue, because I‘ve never saw an perfect iPhone 12 Pro without raised blacks.

can u try something to me , on the phone where u do not have any flicker, but not on videos, simple test , go in a pitch black room, start an TV show with the official apple TV app, when the show start press pausewhen screen is still black at 0:0 ty to change brightness once or twice , and maybe like me u won't see the flicker , cos on this app this doesn't happen each time, but weirdly enough i you flip the phone upside down while paused in landscape , i still 90% of the time have the grey flicker for a split second... so this issues seems related to the gyroscope, cos even without changing brigthness , most of time when u flip the phone like 10 times from having the notch on the right to having it on the left , the grey flicker will appear... i would be very interested if u can test this . thx a lot.

The glow on my 12 Pro has been fixed by iOS 14.5. I suspected the problem was software-related because it depended on the brightness setting and the environment. I hope it’s fixed for most 12 Pro owners.

I went to Apple and they replaced my 12 ProMax, new one is working just fine. I don’t feel like I should’ve had to do that for a $1400 device.

Zollotech Twitters the issue is fixed in 14.5 beta 2. Anyone tried it yet?

With iOS 14.5 Beta2, the problem I think it’s like 80% fixed, because there are some places where I can still find the issue, but it’s good that they have already done something to try to fix this

I have this issue too and it’s annoying.

I went to Genius Bar today and they ran diagnostics to the display. Everything came out passed. The specialist told me that if its a software issue, try to reset the phone and setup as new, do not restore from backup. Turn off true-tone. She set me up for a phone call on Thursday to check whether it solves the issue.

But actually I don’t think my backup interferes with system files or any hardware configuration. Its just a standard procedure to ask us to do when they do not have any advised solution.

It happened to me too! I thought it was some night shift / reduced white point settings, but then I figured none of them are contributing to the issue. I restarted the phone and it became back to normal. I hope it’s not a hardware thing but a software thing Apple can patch.
