    Anyone else seeing that the bottom of their 4S screen (when held in portrait mode, home button on bottom) is noticeably brighter than the top of the screen? It is on mine. Not really a deal breaker but it's a little annoying. Didn't have that issue on my 1st gen, 3G, or 3GS. Especially noticeable in iBooks where you have a solid white screen, or on many web pages.

    Yes, I have the same issue. Really annoying. Very nice 4/5 of the screen, the top 1/5 looks dark and dirty.

    I returned my (3rd) 4S for that kind of issue. If it bugs you I'd suggest doing the same while you still can. Sadly, the screen on that one was the most neutral of the 3 I've had (first was green, second blue).

    The apple geniuses treated me like I have 5 heads. "I don't see it.". He shows it to the geniuses next to him, barely looks at it and says, "I don't see it." frustrating to say the least. He eventually offered to swap my phone as a way to get rid of me, but I declined. Almost all the display models have this issue with a rare iPhone that doesn't. I currently have a vibrant, crisp, and blue screen as a replacement for a yellow one so I didn't want to take any chances. The genius refuse to let me check out a replacement phone without completing the swap first. He says there was no going back once that is done. Interesting enough, my yellow screen is completely uniform.

    Keep in mind if you recently just got yours, sometimes it takes awhile for the glass and the digitalizer to come together. And it could be just that. Have you tried taking a screen shot and then placing it on the computer? And seeing the difference? Maybe show it to Apple? Plus they should EXCHANGE it for you not swap it. Oh and that's if you bought it at an Apple Store. If not then you have to go back to the place which you bought it from and ask for an exchange.

    The four in my household all have very even illumination and are very nice and clear.

    My screen is perfect. I was worried though because back in the summer I compared my 3GS to the iPhone 4 in the store and the iPhone 4 in the store was yellow compared to my 3GS but my 4S no problem!

    No, this issue will be permenant. My friend's iPhone 4 from last year still has the dimming at the top.

    My wife's white 4s got the dimming on top real bad but doesn't bother her at all so I'll leave it alone. But it does bug the heck out of me.

    After looking so closely at these screen, there is at least 3 different manufacturers for the panels. The white iPhone has a warm white screen. The black ones varies tremendously from overly yellow to overly blue. Some are blue and extremely washed out, like pushing gamma to the max. My advice to anybody, if you like your screen right now, don't bother exchanging as your next phone might be much worst.

    I started another threat about this problem, it seems to affect more people already. Will post the pic of my actual screen here, may be I am going crazy but I can see slighty dimmer top of the screen:

    Anyway, most probably my next replacement will have worse problems, so I am stick with this one. Feel like a dumba** when have to explain to the Genius, so better to live with it.

    Wow, you are looking at the worst possible case, dark room and bright plain screen. Yours is still darn near perfect. One of the best I've seen. All the Geniuses can't be wrong. Enjoy. :cool:

    This is how my wife's phone looks like. I have a black one, very similar.

    The top is dimmer. Reading in landscape is very annoying. The bottom of the screen is absolutely beautiful, that makes things even worst as you go up. The dimmer portion looks yellowish and dirty, almost like excess glue particles that got on the screen.

    I think I will take it back and get it another go.

    I don't see anything wrong in these 2 pictures posted above.

    Maybe we could probably see it better in real life.

    Edit-Kmarts picture looks like the left side of the screen is darker than the right. But its the whole left side of the screen from top to bottom.

    Here is a shot how mine looks at 50% brightness level with auto-brightness on.

    Do you think it is acceptable?

    At 30% brightness:

    I don't see anything wrong with your screen. You Defintely need a higher resolution camera. You probably have the same issue with my black one, darker for about 20% of the top at the earpiece. Subtle but I can see it everytime.

    It's always hard to tell even with the best photographs.

    i have the same problem. it's very noticeable when looking at emails or a white background in safari. i exchanged my launch day phone for this reason, got another one, same issue but less noticeable. new one has a speck of dust under the glass however. not been a great experience so far. i will probably try to exchange this one as well.

    Hah, EXACTLY same story as yours!!!!
    Got it on launch day, same day returned because of very dimmer top half, second one is this on the pics I gave here - a lot better, but with spec of dust under the glass....
    Still wondering if it's worth to go for exchange if the next one will have same or even worse problems...

    the screen is no more going to "heal" itself than the people here are going to get over being OCD.

    Darn, looks like I'm not alone on this. My top is dimmer than the rest of the screen. I have been debating whether to get a replacement or not...

    Today I saw the screen of friend of mine, who bought his phone a week ago. That was terrible screen experience- dimmer top and bottom of the screen and one very obvious brighter line across the middle. Also a bit yellowish..
    I think I will forget about replacement for the moment...
    It seems that there is no a perfect one..or atleast any with normal QC

    Got my 4S yesterday. Just checked out my screen with a multi-colored flashlight app and in all colors my screen looks uniformly lit. So I lucked out in this regard.
