store or phone and sent it to you? New or refurb?

Not sure what you are asking. It was a replacement, but at that time I believe it to be a new unit as re manufactured units had not come back yet. Serial was similar to new. I have Apple Care, so they mail the replacement, no need to go in to a store.
 
4S screen yellowishhhhhh

I like my old (15 month) iPhone 4 blueish screen better than my newer (2 month) iPhone 4S.
In regards to color accuracy the 4 is better than the 4S.
My humble opinion

Thank you but that is what I was asking.

I called apple today and they said they would send a replacement out but could not say if refurb or new so he told me to go back to the store (I just purchased on the 7th of this month) to swap so I did and the new one is perfect!!!!!!
Just like my old iPhone 4 finally:)
Thanks

EVERY single iPod Touch and iPhone in the Apple Store is tinted blue. EVERY single one of them. If your display is tinted yellow, it is CLEARLY faulty. I personally don't care enough to make a genius open like 40 boxes to find a perfect one, but it is annoying to have a gross yellow tint to the screen, I would know because mine is tinted slightly yellow. Also, I don't need some bullsh** excuse as to why it's that color. Glue is still drying? Give me a break. When using LED backlighting and rush manufacturing, stuff like this is going to happen.

If it bothers you so much and you take it to get it replaced only to have the genius tell you that, that's normal, just drag him over to one of the displays in the store and then ask why they're all tinted blue and you have a dirty teabag yellow. I'm sure you'll get a solid replacement.

Like I said it is very annoying to have washed out whites on your display, it isn't suppose to be like that, and I don't care if professionally calibrated monitors are that color. The iPhone isn't suppose to have that color. Just look at the ones in the store.

I measured my 4S with CalMan and a Xrite i1 Pro:

The color temp was 7980K Really Blue.
 
Am I right or wrong in assuming that if you buy a new iPhone 4S right now, you will get a blue tint screen for sure and that the yellow screen will only show up in refurbs?

I have a blue tint 4S that I bought off Craigslist in December. I am looking to buy my girlfriend a new 4S this week but I don't won't to have to deal with the yellow tint screen.
 
This isn't really a shocker for me- I'd seen this. I think the blue screens usually have the crisper colors and the yellow makes everything look washed out.

The iPod touch was always said to have the inferior display- but this is not the case. The iPod touch's colors are better.
 
Well, I'm heading to the Apple Store to buy a 32gb 4S. If the screen has a yellow tint, I'm not going to take it though. I will just wait until the next iPhone.

Result:
Wow...the yellow screen reproduced color very accurate like an IPS screen should. Blacks look black, yellows are yellows, etc..., pictures are detailed and color accurate.

Blue Tint screen is a tiny bit of a disappointment. Colors look a little washed out. Blacks appear to have tint of gray. Color reproduction was off and not as accurate as the yellow screen. Only the blank white screen appears to be more vibrant but I suspect this is due to its unnatural color reproduction of "White".

I was playing around with a friends i4 (blue tint) and compared it to mine (apparantly yellow tint, never even knew or noticed for the 20 months I owned this phone). I ended up with the exact conclusion when comparing both. Her blue tint i4 produced a very bright white but I noticed the contrast between all the other colors did seemed a bit dull and washed out. My whites compared to hers looked yellow (when comparing side to side next to her phone, looks fine when by itself) but all the other colors on my yellow tint phone looked more defined and solid. I was pissed at first when I saw the white screens but after playing around with both for a while, I concluded I liked the overall colors the yellow produced.
 
I just received a new iPhone 4S (yellow tint), and had the opportunity to test it with a colorimeter too. The findings are consistent with what already shown.

At 50% brightness:
- "blue" iPhone: 7894K
- "yellow" iPhone: 6946K

The blue is totally off, but the yellow one is incredibly closer to a correct calibrated monitor (6500K). That's something quite unusual in the mobile phone environment, that's why lots of people are complaining.

I'm really happy about my new "yellow" LCD, and really hope Apple continues to calibrate near 6500K for the next devices... after playing 2 hours with the new 4S, the old "blue" one looks totally crap!

Same here, after using a correctl calibrated display, as others would likely call "yellow", a blue tinted phone or iPad just looks like a defect. Color reproduction is cheap at best, blacks during movies are ugly as hell and it is so annoying reading text on a blue display. Especially looking at photographs, every prrson looks like a zombie and nature shots just look dull.

My old iPhone 3G was blue as an ocean, from the first moment I didn't like it but thought that's just how iPhones are supposed to look. I learned better very shortly afterwards.

Actually, someone in the iPad forums pointed to a study that showed that constant exposure to blue lights is way more stressful for the eyes than green or yellow colors. I believe it.
 
Strange thing! After 3 days I measured my iPhone 4S again, and it's actually shifting in color.

On March 28 it was 6946K and x,y was 0.303,0.341 (noticeable green push)
On April 1 it is 7121K and x,y is 0.301,0.331 (cooler temperature, and much less green push)
(the target is 6500K and 0.313,0.329)

I always believed the rumor about the glue causing the issue was ridiculous, but the display indeed becomes cooler after use.

I'll continue measuring the device with the colorimeter in the next days/weeks to see if it settles.

On Wednesday I also scheduled an appointment with a Genius in an Apple Store, I'd like to see other display iPhones (and possibly measure them with the colorimeter if the Genius agrees).

EDIT: I also measured contrast: white is 397 cd/m^2, black is 0.435; that's excellent: 913:1 contrast!! Much better than official specs (even if max brightness is less than advertised 500, but I have no problem with that).

I just tested the device after 3 hours on a white picture and max brightness.

Shifting again... now the screen is measured as 7246K temperature and (0.299,0.329) !

When I first unpacked the device Green was 11.4% brighter than Blue, now they are exactly the same. :eek:
 
There's some variance in the 4S too fwiw. I have an AT&T 4S and it has a slightly yellow screen. Not terrible by any means, but it's there. My dad's factory unlocked 4S on the other hand is almost perfect

Had the same issue with a refurbished iPhone 4 32Gb i just got today.
i didn´t need to put them side by side to notice there was something wrong with the color tones, the contrast, etc.
I personally found it very annoying, and, like many said, the impression I get is of a faulty, non Apple standards unit.
Regardless of whether you prefer colder or warmer displays for PC or Tv, I see that the retina effect weakens when you have a yellow tint. Small character letters have less practical resolution, this is due to the fact that black or dark blue become grey or light blue and the white background becomes less white (yellow!!) so instead of black over white I get grey over yellow which is perceived for me as less resolution/contrast, so more like an 3G/3GS. I had them both and the MAIN reason why I changed to iPhone 4 was for the retina display.
I found this thread (I knew thew this site though) searching on the web to see if more people had the same problem as I have, and unfortunately I see that it is the case. I´m not surprised until what point people can be annoyed by this.

Eclipsevv: Do you think that a refurbished iPhone 4 will experience the same effect you observed with the 4S?. Great work
 
FWIW here's a shot I took with my 40D with the white-point set to 6500K

Fix yellow or other color tint iPhone iPad

Jailbreak it and install springtomize. Go to animations and turn custom gamma on. Now you can ajust the RGB levels. Mine i set approx. -10% red and -5% green. Now white is white.
 
I'm using iPhone 4 blue tint my friend using iPhone 4 yellow tint. We compared our iPhones we had lot of questions
1.which one is best?
2.which one is original?
Or same?

1. Best = subjective.
2. Both are original, unless someone had their screen swapped at a thid party repair shop.

1. Blue is best and clear!
2. Blue tint

I had a yellow tint and it is if one looks very closely at it is not as clear as a blue tint one, I returned the yellow for a blue one. Yellow tint was washed out slightly also.

Best of luck.
