Do stop me if you've heard this one before... but customers are complaining that their shiny new iPhone 4Ss are suffering from a yellowish screen.
Users on the company's support forum say that colors on their new phones are feeble, and overlaid with a yellow tinge.
"My 4S screen is less contrasty, and the whites are more yellow (beyond 'warm') compared to my iPhone 4 screen," says one.
"The colors are less vibrant, and some are pretty washed out. I've also noticed that the screen is more directional than the 4 screen, and in some viewing angles it's more yellow, and in others it's more contrasty."
It's a problem that's been seen before. When the iPhone 4 launched last year, users complained of precisely the same issue, which was eventually ascribed to swift shipping - the glue used simply hadn't had time to dry and cure properly.
To judge from the comments on the Apple user forum, the problem is much more prevalent with the black models than the white. Users are particularly miffed that the exceptionally bright lighting of Apple stores makes it harder to detect, so that the issue only really shows up when they stagger out into the real world.
If the problem is indeed the glue, then it should go away of its own accord in a week or two. If not, Apple may have to deal with a lot of customers demanding replacements.
Some users are saying that the problem shows up more with the phone at certain orientations, implying that there could be some change to the polarization of the screen.
Apparently, Apple is, currently, allowing users to exchange their phones if they really insist.
