Prefix G9N: Samsung Good Grade panel (Very low chance of being a bad panel).
Prefix G9P: Samsung Poor Grade Panel (Moderate chance of being a bad panel).
Prefix GVC: LG Good Grade Panel (Moderate chance of being a bad panel).
Prefix GH: LG Poor Grade Panel (High chance of being a bad panel).

In terms of panel quality and likelihood for not have a green tint:
Samsung Good > LG Good > Samsung Bad > LG Bad.

Interesting they put LG Good before Samsung Bad serial #, odds wise.

And also interesting the 'poor' panel LG has high chance whereas Samsung 'poor' is only moderate


...if this is a reality, I have no idea. But that to me means there's more LG lemons by this logic.

Still probably lots of lemons of both types to go around, and excellent of both, and poor ones that pass flying colors like mine, and 'good grade' that fail every test, and same with LG.


it's fun to learn mine is Samsung. but if I learnt it were LG, I would still sing my praises about this particular panel. Months later, its still a beauty!

Thats all fake news created by delirious posters.
Hard to say for use but it looks it might have some relevance from what I have seen myself is that in 6.1's G9N seems rare. Originally ordered two 6.1" Pro's for me and another family member. One came with G9P and the other with G9N.
One with G9P was terrible, non uniform with dimmer bottom half and greenish compared to upper half but it had rather cool whites. Another one with G9N has perfect uniformity, absolutely perfect! It is a bit on the warm side (probably something some peoples would call yellow), but seems rather accurate D65 to me.

Then I tried replace one with G9P and all 4 I tried came always with G9P and all had more or less bad uniformity, it only changed place which part was dimmer (upper or lower) and there was always different tint between up/bottom.
Also went to check demo units in my local store and all I could find looked similar as my G9P and I then even ran checks to see what panel was in and it was G9P in all of them. So again, this is my experience with limited sample (around dozen) and only one of the screens was acceptable in my opinion (G9N).

Anyway, my point for those who want cooler display and do not care about screen brightness or tint uniformity, look for G9P. I would have preferred G9N myself but after too many attempts trying to get one failed... :(
I'd take one like the other phone we got in first order with G9N anyday.

I'm talking about Pro in 6.1" size. It might be different case with Max sized screens.

I have a G9P (iPhone 12 pro) and a G9Q iPhone 12 pro max. Both are uniform I’ve had no problems with the screen except the G9P 12 pro displays raised black and green tint. My G9Q doesn’t have the green tint nor the raised black issue, but I’ll constantly check if it would have the issue after a while.
The G9P screen seem whiter/cooler though while the G9Q is a little bit warmer but in a good way, like, it was relaxing in the eye, not too yellow and not too blue, for me, just perfect. I’ve read from a post that G9Q is quite rare too, I’m not sure if true though.

Have you actually looked for uniformity issues with different ways? I mean I know most peoples are immune to uniformity issues and they only notice and see them when I actually point them out what to look for but even then most do not think it is bothering them.

Sounds like G9Q is pretty identical to G9N and I agree even N is on the warm side and (perhaps some call it yellow) it is very pleasing to eye and easy to watch. Every G9P I have seen are pretty cool white, more or less even bluish with TT and NS off. But every P I've tried have issues with uniformity from noticeable to terrible, Very obvious to see if turning on NS and adjust temp slider to warmest possible. Some have practically red half screen or some have narrow part of the long end or then just reddish corner. And each one had either dimmer bottom or upper half, usually it seem to be bottom for some reason. Tip, turn the phone to landscape position and it is easy to see if upper/bottom is different then. N is just perfect but I just could not find one. :(

Anyway, my point is that probably N is the most accurate and uniform panel but I understand that some peoples rather have cool bluish whites, even despite of uniformity and the fact that in bluish screen uniformity issues are harder to see. That definitely explains why some peoples seem to like using color filters to make screen cooler.

My girlfriend has a 12 pro max G9N since the day of departure. I have a G9Q and my screen has aged much better, it is noticeably whiter and the texts look cleaner.

I would not know how to describe it but the G9N read the "thicker" texts and in my G9Q the texts are clearer, I would not know how to describe it but I totally stay with the G9Q panel.
 
I've honestly given up and just bought an iPhone SE 2020 (in lieu of a 12 Mini). I figured as we're now 6ish months away from the iPhone 13, I may as well just wait. Found a brand new iPhone SE for quite cheap and pulled the plug.

Good luck to the rest of you! It's been an honour serving with you all.

How did it just aged better? By itself? Do u have the same opinions about G6 models.
 
I just got iPhone 12 Pro Max day before yesterday, right away I was disturbed by the yellow tint 😫 I remember reading how superbly colour accurate iPhones are, how can anybody use one like that, it's so weird to take photos, everything tinted yellow, when I transfer the photos to my new iMac (27 2020) colour look accurate to reality, my previous over 5 years old 150$ android phone (Meizu M2 Note) display match the iMac display, what a disappointment...

Ridiculous that turning on true tone makes the display even more yellow like night shift even tho in my room I have cool daylight lightbulbs, with them on turning on true tone on iMac it does nothing (it does work appropriately if I turn the main cool bulbs off and instead have lamp with warm bulb on).
 
Conflicting reports out there, heard the pro models are Samsung panels, then next minute pro max and mini using Samsung panels. 🤔🤦‍♂️😂
I have feeling A

LOL @ your last paragraph , I think Apple got their True Tone and nightshift done wrong, look identical.
 
Did 14.4 start to mask the display serial number in device tree txt file of sysdiagnose?

was able to find it on 14.3 on my mini5 - fn1 not sure who makes this

but 13.5 on se2 yields FV1 - today I learned this one is packing a toshiba. It looks good to me

14.4 on my se1 seems to not find the serial number.
Just curious !
 
I am with my 5th Mini now, 3 returned because of display issues. Mostly yellow tint and washed out colors on the devices. Only 2 including the new one had OK to good display, both were iPhone 12 mini in white. Strange. The other two black iPhones had yellow tint and washed out colors.

All were produced in november, week 47/48. Although all were F1 or F4 serials. But it is strange that both white iPhones had better displays and both black worth display quality.

I have to wait till tomorrow when it is day again to tell for sure. But in the dark colors with TT and NS off are quite good. Of course no comparison to a LCD. But it seems quite white for an OLED. Have to wait to tomorrow. But atm I am quite happy even though this display has quite some blue color shift when tilting the device. Wasn't that extreme with the other devices. But if I had to choose between yellow washed out display or blue color shift when tilting I choose the latter.
 
I'm experiencing warmer colors/yellow tint too. I initially thought it was night shift, but nope, seems the displays just suck this year. Hopefully a software issue but I doubt it at this point. Will settle for a recall.
 
I've been faffing about with the accessibility colour settings for the past couple of hours and have come to the conclusion that the colour my phone shipped with was perfect. How do I just reset the colour profile to the 'default' setting? Thanks.

Edit: Oh, I just had to turn Colour Filters off. I'm a moron pfft.

All the settings in accessibility, display and text should be off apart from auto brightness if you use that feature.
 
Roll on 14.5

With 3 iPhone 12 devices in my family, I realised that the term Pro Display XDR automatically means horrible yellow tinted displays marketed to gullible people by slapping Pro term. Tbh, there is nothing Pro about these yellow displays and enabling True Tone makes matters even worse.

Heck my 3 yr old iPhone X has better neutral display compared to the permanent “Night Shift mode On” displays of 12 series. I cannot comment on iPhone 12 Pro models though.

The same yellowish tint is present on the new Samsung Galaxy S21 line up. This is how these OLED displays are supposed to look (for whatever reason). This is not a defect or software “issue” that’s going to be “fixed” by an update.

Either switch to an LCD iPhone or learn to live with it.

Yep, like I mentioned many posts ago. Samsung OLED panels year on year have increased blue light filter which results in layman's terms looking yellower.

Which is fine, but please explain why are some displays MUCH more yellow than others despite the same phone model? +-10% manufacturing variances is a hell of a lot when you are talking about white point.
