    Have any of you noticed a checkered pattern on the screen when black is being displayed on the screen? On my iphone on the home screen, I can see a light checkered pattern on the black screen behind the icons. This is my second iPhone as the previous one had dead pixels, and my previous iPhone did not have this light checkered pattern on the screen. I have access to another iPhone as well, and it does not have the checkered pattern either.

    It is very faint, and I don't know why it bothers me, but I just want the phone to be perfect. I've heard reports that they have several different manufacturers making the screens, so maybe it is just normal on my new screen.

    Just curious if anyone else has this? I may be able to post a picture if needed. I'm not certain how well it'd come out. The really really odd part about it is that the screen looks awesome when you first turn it on and it has the black around the Apple logo. However, half-way through the boot-up process is when the checkered pattern appears. I'm not sure if this means it is a software issue, or if it is something else.

    I can't say I haven't considered returning this phone as well, but I hate to be so picky. Anyone else notice this?

    I actually just posted about this, if you could please do a complete restore on the iPhone and tell me if that helps. If it does not i suggest we both request exchanges for our iPhones.

    I restored mine last night, and it did not make any difference.

    This is really going to make me mad if I have to go exchange it. The Apple store is 1.5 hours away from me, and this would be my 4th trip. Last night I was there because my girlfriends iPhone just started crashing non-stop. I should have exchanged it then I guess.

    You think a software update could address this issue?

    Are you talking about lines that run both down and across the screen? If so, I have seen this on every iPhone I have looked at (about 7 of em). I thought it was just the grid pattern used to pick up touches on the screen. I can only see it when looking at it from weird angles or if the screen is very dark. I think it's normal, but I may be wrong.

    100% Normal

    Should be a faint grid you only see in intense sunlight and certain colors (or off). It is part of the multitouch techmoooology.

    I have better than normal vision and still see nothing. Adjusted brightness, took it outside while on and off, etc. Nothing shows up at all on mine.

    Its not something your supposed to see. This is my second iPhone and the first one had no such defect. It is a defect with the screen and i called apple about it. They are away of the problem and are going to address it with a recall ala powerbook battery. However, if you do not want to wait then you can go to the apple store and they will replace it for you on the spot.

    Daniel,

    Are you going to exchange it at the store or wait for Apple to recall it? How did you describe the issue to them when you called? I would like to call them myself so they at least have a record of the problem.

    Thanks,

    -Steve

    Im going to exchange it today and make sure that before he gives me the new one im allowed to look at the screen. I told them it was as if there was a matrix of white dots below the screen. I was told this was a defect because certain panels they had gotten from a different company where not quality checked so what your actually seeing is the multitouch matrix. This should be seen at anytime and could actually lead to harming the multitouch layer of the phone.

    Please let me know how it goes. I may just call them and see if they can send me one, and I'll send the old one back. I'm really tired of driving all the way to the Apple store well over an hour away.

    are you sure its not normal? i was looking at mine and its there... i never thought it to be something wrong with the screen.. i never got to look at other ones... an apple person told you that it is a faulty screen or you heard it on a website or something? did you get it exchanged without a problem? thanks

    it looks like this...

    http://electronics.howstuffworks.com/iphone2.htm

    ...is what we are seeing

    it would help if there were more posts by people saying whether they can see the grid or not... i can see it when i tilt the screen with overhead lighting.... when looking directly at the screen i can see a faint pattern of white dots

    i was told by an apple iPhone engineer when the lady from applecare had no idea what i was talking about. It basically has to do with a faulty LCD manufacturer that was used. Some iPhones have it, some dont.

    Same here. I have a hard time believing that this is not normal. When the screen is on, or there is no glare from overhead light I can not see any grid pattern.

    i still see the grid and white dots when the screen is on...


    i also noticed that the phone looks normal when it starts booting, but halfway thru the boot process the white dots show up.. maybe when the multitouch sensors turn on?

    i never thought it was a problem, but now im starting to think its a faulty screen

    I can assure you after having another iPhone myself and looking at others, if you are seeing the 'white dots' during boot like you describe, then it is not normal. I see the grid lines when the display is off and under direct light, but the white dots show up when it is running. This is NOT normal, I assure you.

    i've got this too... i'm not sure if it's "normal" but i can say a large percentage of them have the dots. this is my Yes seventh iPhone. well technically 4th. when i was in the apple store exchanging the for varies reasons i had to go through 3 in a row because they all had dead pixels. Of the 7 about 3 of them had the dot pattern. plus they guy i had to persuade to give me a new one because of the dead pixels had the dots on his too. I would think twice b4 exchanging. You might end up worse then you began.

    I find it annoying that they're there, but it doesn't effect anything but pure black, if you look at the right angle and look really close. After six bad ones i'll stick with this.

    it's really had to photograph. the dots are very hard too see. i'll give it a shot though.

    It would be nice. But if they are that hard to see, what's the big problem?

    Having read the posts above, my suspicion is that the pattern you're seeing is a type of moire effect due to the spacing or alignment of the touch screen grid and the display pixels. If this is the case, it could be that there's some variation from one unit to the other, depending on how the sensing grid is overlaid over the diplay. Could be that very small variations in alignment, that could be very hard for the manufacturer to control, would cause this effect.

    I generally agree, that it is a layer of the touch screen. The fact that you don't see it from all angles and that it only becomes visible halfway through the startup. I don't think it's the LCD. My guess is that the touch screen only becomes active halfway through startup and perhaps becomes less transparent. then the alignment of it with the screen will make it more or less visible. from varying angles. Mine can be seen best from a lower left angle then then fades as you get more over head. From a top, of right angle you can't see it. Here is a photo of it at the angle of greatest visibility. i shot it with a 300mm macro lens. So it's quite magnified.
