    I'm trying to determine if the yellowing on the 3GS screen is related to the defects or variations in the bonding process between the screen and screen coating? The glass screen and oliophobic coating in bonded by a material and I think the yellowing is caused either by the uneven application of the coating or bonding material.

    has anyone taken the glass off their phone and been able to see a discoloration on the screen when held up to a light source, I know it's not very scientific but because the yellowing is so evident it should be visible under normal lighting conditions.

    Can you post pics of this if you do decide to investigate further?

    The 3G had yellow screens as well, it's just amplified on the 3GS apparently.

    with all the people talking about the "yellow screen" I have not seen one and am kind of curious. Does the yellow show up on a screenshot? would be interesting to see

    The yellowing is to do with hardware, not software, so it wouldnt show up in a screenshot.

    I was comparing my 2nd gen iPod touch to my 3GS yesterday, and I much prefer the screen on the 3GS. I wouldnt call my screen "yellow", but it just looks a lot warmer and nicer. In comparison, the screen on my 2nd gen touch is definitely yellow compared to my old 1st gen touch (now my dad's)... but the 1st gen's screen looks like absolute crud compared to either of the newer devices.

    Generally from what I've both seen, heard and experienced, it'll stay as "yellow" as it is when you first buy the unit, it's not something that worsens.

    I know it's not a 3GS, but I'll try and take pics comparing my 1st and 2nd gen touch soon as an example.


    Here you go guys, from Google Image Search. The phone on the left clearly has the yellow screen.

    Quite apart from the left screen in this pic being bluer, this sort of thing is meaningless because the appearance of the screens in the photo depends heavily on how the camera has set its white balance.

    For what it is worth...

    I compared my 3G with a 3GS.

    The 3G was noticeably more yellow
    The 3GS was bluer (personally I prefer the blue)

    If the left is yellow, then the right one is shocking :eek:
