iPhone 15 Pro iPhone 15 Pro - grainy screen

[Gameboi301123]

Saw this grainy mura effect thingy on my 15p, got a screen replacement from the apple store under warranty. It hasnt fully gone, but it is wayy better now. Like its gone down by 70%.

most displays seems to be having this to some extent this year (this was tru of iphones 13 and 14 too) For the devices on display in the apple store , a couple pf those had it too. Most people don't notice it so maybe we’re all just geeks haha.

For those who may concern:
Here is what i found (i have swapped more than 5 units and observed 20+ units at Apple Store)

iPhone 15 pro series use display from Samsung and LG.
In terms of display part code:
Samsung: G9N G9P G9L G9Q
LG: GVC GH3

Usually, Samsung displays have a greener color tone and more aggressive color shif at angles, while LG displays have a reddish color tone and alot less color shifting at angles. As the pics showed below.(LG GVC on the left, Samsung G9P on the right)

Also, most of LG displays have the “grainy paper texture” issue.(I have seen multiple LG displays have this problems)

Thanks for the info, but since you find out which manufacturer the screen is, you use an app??? There is a log on the iPhone that identifies her???

did apple fix this issue with the 16s?

 

[NotApplicable]

The 2 launch day 16 Pro Max’s in my household are LG (GH3)

So much for Samsung M14 panels

But I don’t notice any graininess

My 16 Pro have intensive grain, visible from 30% brightness and up; GVC.


Also if you use Mac, display code can be checked using:

brew install libimobiledevice

idevicediagnostics ioregentry product | plutil -convert xml1 -o - - | xmllint --xpath "string(//key[.='raw-panel-serial-number']/following-sibling::data[1])" - | base64 --decode | cut -c 1-3

is there any other solution without a Mac to display the display serial number / information of the iPhone?

Try 3uTools on a PC.

Makes me giggle when some state samsung devices aren’t effected by the grainy denim material effect . Search on Reddit or google for s24 ultra and grainy panels. Go ahead. 😂

My new iPhone 16 Pro Max suffers from this issue and the display is Samsung G9N. My old iPhone 15 Pro however did not have this issue.

One thing to note is that this artifact apparently is not visible to all humans. If you are very near-sighted and are able to see things at very closes distances clearly, you are probably able to see it. Like when you are lying in bed and hold the phone close to your face. Not only it's grainy, but also it's sort of flickering resembling white noise.

I think the issue arises mostly from the green pixels. If I display a solid green image at medium-to-high brightness, it will be more visible. (I used this website to test RGB pixels: https://lcdtech.info/en/tests/dead.pixel.htm)

I did that green card test with my eyes about one inch away or so from the screen. It was an experience, I’ll leave it as that 😆
