I must say, I had the opportunity to buy 4 iPhones, with a week apart each, in December-January, so thanks to this forum I was able to validate everything and in the end I kept the model F2L Week 52 (21.12 - 27.12). I had models G0N, G9N... BTW, is a 12PM 256GB
Got a tip for us?

I'm on my 3rd mini now. This 3rd one seems better, display seems whiter. What about uniformity though, mainly grey uniformity? At low brightness and sometimes even high brightness, grey uniformity isn't good, it's quite uneven. Noticeable in discord which uses a grey background. I've read that this is normal for OLED's though
I agree with Turkey. I bought 12 iPhones and noticed the screen was yellow
I'm on my fifth 12 Pro and all have issues with screen, mostly uniformity. All with G9P so there seems to be hard to find good one from those. We have another 12 Pro in our family with G9N screen and it is perfect... So rarity of G9N's and the fact none of the G9P's I've seen were good makes me think if it looks like a duck, swims like a duck, and quacks like a duck, then it probably is a duck... 
I'm done with this.

I was hoping you'd be persevere with this until around Sept or Oct time.I'm on my fifth 12 Pro and all have issues with screen, mostly uniformity.

Yea don't waste your time and energy looking for a unicorn. XDI'm on my fifth 12 Pro and all have issues with screen, mostly uniformity.

I dunno if genius bars are running where ever you guys are or in general but could you request a g9n and see if they will?
the serial is printed on the Genius Bar phone box
First of all, the G9N, G9P, or whatever it is, is a serial number for the screen itself and not the device. So even if you wanted to, I don't think they will know. The device serial generally would start with F17, F2, DN, G6, G0, FK.
Even if you could request those G9N, etc, it would likely have to be a screen replacement only, even then you could ask but who knows.
I'm curious to know how you find out the screen serial number if you are on a Mac? I know you can find what serial number the screen is if you are a Windoz user.
good point. My mistake
I dunno what panel mine is I refuse to run 3utools but I’m still elated with my launch unit. Thank god.
You can do it within iPhone too, if you want. No need for additional app to check.
Yellow screens have been a problem for me for years. It even happened last year with the 11 and I ended up keeping my xs max. I have purchased 4 iPhone pro max this year and they have all had yellow screens. I currently have two now one screen is G9Q and the other G9N and they are both similar with a yellow screen. Both serial number start with F2. Not sure what I am going to do but it has been driving me crazy because I want to update my phone.
You would run sysdiagnose:

Just did the sysdiagnosis. Looks like I have the G9N. Not sure if that's a good thing or a bad thing but My serial number starts with F2 Week 50 build

It doesn't make a difference, one of my G9N had very bad green tint.
Got a G9P, the one that visually looks great to my eyes. uniformity, good blacks, no green tint, no yellowing.
Seems like this is the 'Samsung generally bad' panel. But not sure how much faith I place in that, may have just won a losing numbers game
iPhone 12 lottery in general seems like a losing game

Yea I know it won't make a difference. At least mine's perfect for my needs.
Yea as long as it's good visually to your eyes should be good. Even with my G9N,Everything is good, no yellow tint, no green tint when it's dark, very good blacks and very uniform. It's just luck I guess.
So is mine, it’s acceptable. Here’s my story on how I ended up getting 4 12PM. First one , intermittent SIM card read error even with new SIM card, second one, lower frame rim edge scratched up, so much so nails would catch it. Third one green tint.
saw this post on GSM arena, might've already been mentioned not sure how true
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.
haha figured
I think its interesting whether you got LG or Samsung, but beyond that, yeah a roll of the dice
people who have a good panel that updated to 14.5 beta 2, is it still a good panel ? Color temperature unchanged, no additional issues display wise that weren't there prior?
Since this is supposed to have the 'green tint fix' for affected people. I dunno if it works for all extremities of it but what I read I think?
I also eyeballed a handful of units when I went to go pick up a band back when you could check them out, and across all models (mini, max, reg, pro) mine looked brighter + cleaner. I got a gem
