iPhone 12 Pro iPhone 12 Pro “raised blacks” display

Here is what I did. It’s not scientific as I had no device to measure the exact brightness levels. Set the brightness to 70% and let’s assume this is 500 Lux. Turn on the “reduce white point(rwp) set at 100% This dims the brightness considerably say about to 100 LUX. Raised blacks visible in both cases.

switched off the RWP

Now I raise the display brightness to 100% and the brightness is at 800 lux. And then I switch on the RWP. Brightness fall to say about 200 lux. NO raised black in both cases.

so when the screen was displaying raised blacks at higher physical brightness of 500 lux at 70% brightness setting and not displaying them at 200 lux at 100% brightness setting with RWP on , this does look like something related to the brightness slider Adjustment via software than an actual hardware fault. So Apple should be able to fix it 🤞

again this is not exactly scientific. But just general observation.

Hello all!

I had an interesting experience today. I set the brightness of the display to 70% (where the raised black issue does not exist) and activated „Reduce whitepoint“ at a level of 80% to 100% in the settings. In this combination, the display is about as bright as it normally is at 10%, but the raised black issue still does not exist.

So in my opinion this could be a proof that the raised black issue is a iOS-bug or display-firmware-bug.

Maybe you could test this on your iPhone 12 Pro, too?

Thanks for pointing this out! :)

Latest Samsung Galaxy S20 series update fixes green tint bug

The display issue began plaguing some S20 units last week. Just last week we reported on a strange green tint bug found on some Samsung Galaxy S20 Ultra...

this issue looks similar to what we are experiencing and was fixed via OTA. Let’s hope Apple works something out to fix this soon.

Yes this is a known issue , I thought you were aware as I mentioned it in my earlier posts referencing Samsung panels. ? Google search oneplus 8pro and you’ll get lots of hits also.
Apparently the S20 had a software update some months after it’s initial launch date of April 2020 to remedy this, but I also had one Samsung Note 20 Ultra that possessed this issue as well. According to Samsung the issue didn’t effect my model SMH. On the other hand the oneplus 8 pro had this issue and I believe still does. I sold that 2 months ago, so not up to date with its latest news.
The common denominator is that all these devices that are affected use Samsung OLED technology. Karma will get them again soon.

Just got my new 12PM. Production week: 51. My previous one had flickering and raised blacks (slightly up by the notch), but this one doesn't. I'll take some photos when it gets even darker outside. Might keep it even though the screen has a yellow tint.

Guys have you tested the OLEDX app.

apps.apple.com

‎OLEDX

‎A simple Clock/Information Interface made to take advantage of the iPhone OLED displays. Keep track of time, add a personal note, check the weather, add icons or images to the Information Interface. The interface takes minor jumps each minute (3 pixels), this is built as a safety measure for...

There I have true blacks even with 0% brightness with my 12 Pro Max G0N week 49.

Can you test please?

UPDATE:

Ok i have raised black. But if I raise brightness to 100% and after that to 0% I have pitch black. Strange ...

If going from 100 to 0 gave you black, how did you get the raised blacks? 100 to 25, then 0?
 
Did test it again. This time I had both problems, both pulsating/flashing and constant. It was constant below 25% and pulsating below 50%. It is so vague that I wouldn't be able to see it unless it is completely dark, but it is bad enough for me. I'll call Apple tomorrow.

Must have missed that. I saw it now.

I feel that the issue is due to the algorithm apple is using to adjust the brightness with a combination of AC and DC dimming to reduce eye strain due to flicker.

Never expected such thing from samsung. Had pretty much flawless displays in my previous phones (S7edge, S8+, Note 9, Note 10+.

It doesn’t really matter at this point but another common thing is these were all higher refresh rate displays.(s20, opo 8, pixel 5). what if iPhone 12 has a higher refresh rate display and being driven at 60 hz due to driver limitations (there was leak that Apple couldn’t source drivers with good enough yield for 120 hz displays this year before launch) 🤔

I don’t know, but I can assure you that the green tint was also present with 60hz enabled on both my devices.

Exactly. Not sure about others but S20 was doing it especially when it was running at 60Hz, in some apps when the phone decides to switch to 60HZ automatically.

In the comparison units without the issue in those photos, the blacks are raised still. I don't have a green tint issue on my 12P, I just have raised blacks.
 
Commenting to say that I got my 12 Pro Max just yesterday, and the first time using it in a dark room I immediately noticed the raised blacks issue.
Hoping they can fix it soon.

I have a direct line to a supervisor from Apple Care+ and he told's me that Apple knows the issue but this issue is not a software bug, it's an hardware bug. That's why he send me one replacement after another...
I hope that a firmware update will fix it, because all displays can show real black (at my device above 65% brightness), but the questions is when? I don't want to wait until iOS 15!

Interesting.. All supervisors till now were telling it's a software issue that needs to be fixed.

I think it's the first one speaking about HW.

I believe this too. This issue here sadly won't be fixed with an update.

Nothing changing until fix production. The fact that some have it and some don’t keeps leading back to poor quality panels. Apple seems to still be okay with sending them out the door in lieu of only allowing quality or ones that meet higher standards. Because, average consumer may not notice. So may units out there they could never do a service program.
 
I think it has to be hardware too as not sure how one device can be different from another as it varies a lot
 
Haha oups, I spoke too soon.

Below around 50% brightness I see the raised blacks and occasional flashing. Bizarre!
 
My OLED TV had occasional flashing in black areas and LG fixed it eventually. Never had green though. lol.
 
Green tint is still there below about 20% for me too.

I wonder if this is done purposefully as when I compared to an 11 PM, when scrolling the 12 PM never had the ghosting or scrolling issue due to the pixels not being completely off where as the 11 PM did have that issue
