Special Request: please post your LCD Panel ID & first 5 of Serial
(Click here to view the original thread with full colors/images)

Posted by: Marc_G

Hi,

I'm trying to find out if there is a correlation between the Factory ID and the LCD Panel ID of recent iPhones.

It seems that there are currently three LCD Panel IDs:
5755136 - the original, brighter display that looks more "washed-out"
7455232 - which has the "negative-black" issue
7451392 - the new screen that has no issues and looks "gorgeous"!

As far as I can make out, the iPhone's serial number is broken down as follows:
1st two digits = Factory ID, i.e. where the iPhone was manufactured
3rd digit = year of production, i.e. 7 would be 2007
4th/5th digits = week of production, i.e. 39 would be week 39 (Sep. 24-28)

I've already gone through two iPhones, which both had serial numbers starting with 7R7, but one was week 35, and the second was week 39.
Unfortunately, both had the first 7-series screen and had the negative-black issue.

So, if you could, please post the following information about your iPhone:
Serial Number = XXXXX
LCD Panel ID = YYYYYYY

To retrieve your serial number, simply look at the back of your iPhone; or, if it's too hard to read, go to Settings -> General -> About.
To retrieve your LCD panel ID, dial *3001#12345#* and hit Call, then select Versions, and read off LCD Panel ID.

I will start with mine for purpose of example:

iPhone #1:
Serial Number = 7R735
LCD Panel ID = 7455232

iPhone #2:
Serial Number = 7R739
LCD Panel ID = 7455232

Thanks a lot!

Can you please post at least the first two digits of your serial number?
These will indicate the Factory ID which tells us where your iPhone was manufactured.

are you sure your phone doesn't start with a 7 and a letter for the serial number?

Edit: Is it different on refurbs and that's how they're identified?

Yes that's the plan.
I hope to compile all the entries and attempt to correlate the Factory ID with the LCD ID.

I'll give it a few more days to get as many responses as possible.
Thank you all for your time!

Yes, you are right: there doesn't seem to be a correlation between LCD ID and manufacturing week.
However, I'm trying to make the correlation between LCD ID and Factory ID.

Again, could you please post your first 5 serial numbers as you are one of the few who have the "good" 7=series LCD?

Thanks

It wont matter anyways. I was convinced that Week 38 was the best production week to get a good 7 series screen, i got a week 39 today and it had the same screen!

and i've read of people who have week 38 with a bad 7 series lcd. and besides that, the apple store absolutely refused to handpick the iphone for me (and look at a few serial numbers on the boxes). they said its against corporate policy, and that if there was a problem with iphones with a specific serial number, they would be notified by apple themselves.

i just got a good week 39 iphone with a good 7 series screen out of luck of the draw. go figure.

Both screens are set to auto-brightness and in a dimly lit room on a dark background. Neither have negative black issues or white dot problems. But the one on the right is brighter. You can manually crank up the brightness so the newer phone matches the brightness of the older phone.

you are mistaken. left iphone is 7459072. i can see it from the picture.

7459072 should be the higher quality lcd screen. now i am confused.

You are right the left iphone is 7459072. Not what I previously posted. I took it there were only two 7 series screens, and I just used the opposite of what the OP posted for the other. I will correct it.

But I do not think the 7459072 is "higher quality"

The 7459072 screen kind of looks yellowish to me. Compared to the other screen. The older (one on the right) iPhone is actually mine, the other a friends.

Thanks for pointing that out to me.

Posted by: Marc_G

So it appears there are actually THREE 7-series LCD IDs:

7455232 - the most common one that can have the negative screen issue
7451392 - so far only 2 reports of this one
7459072 - four reports of this one

I believe most everyone has preferred the newer two over the original 7455232, and I quote:

Characteristics: also just as bright as the two 5-series I've compared it to. Rich, brilliant, saturated color, a little more so than the 7455232 model. This LCD is warmer, noticeably warmer than the 7455232. Very nice solid rich blacks. Absolutely no dots/grid. (I looked using a jeweler's loupe)

I think your 7457092 might be defective honestly. That's the first I've heard of someone complaining about that LCD version. It does not look from the pictures alone, but then again, there is not enough detail. I hope all works out well!

Posted by: thadoggfather

For the record, I would be able to live with a negative black screen if I knew that they were all like that. But the fact that there are some, and in fact many, iPhones out there without the problem would make me look for one until I found one. Especially considering I paid $400 and the screen is the most important component of the device. To each his own though.

That's just the way my brain operates.

No one is complaining, the other phone looks just fine. At least up until the point you put the two side by side. (if that were directed at me that is)

Not sure about the whole white dot issue, but as far as I can tell, no color issue...

UPDATE: I loaded the Jay-Z album pic and could see the person when I was looking straight at it, or slightly tilted. Tilt it about 60degrees and i can only see the text... does that help?

It sounds like your coworker has a "good" 7455232 screen.
About half the users that have reported having this LCD ID do not have the negative black issue, the other half does...

Posted by: deanfx

Ok the phone on the left is the older phone. LCD Version: 7455232

On the right is the newer phone. LCD Version: 7459072

There is definitively a negative black issue with my phone. The picture above makes it look a little worse. So it is actually not as bad as that pic makes it look, but it does not look as good as the newer iPhone.

I also checked out the greyscale url and you couldn't tell any difference from that small picture.

Posted by: Marc_G

Ok, since there haven't been any new additions in a while, I thought I'd give a preliminary update on where we stand:

5755136:
Out of 5 such screens reported, 4 were from the 7R factory and one from 7S.
Four were fairly early weeks (26, 26, 27, 28) while one was fairly newer (36).
Note that none of these screens have the negative black issue.

7451392:
Only two such screens reported, and only one of which has details: factory 7V and week 29.
I have PM'ed the second user, asking for more information.
Note that these do not have the negative black issue either.

7455232:
Out of the 19 such screens reported, about half have reported the negative black issue (10 vs. 9).
Three were refurbished, so we don't have factory IDs, but most reports (9) show a factory ID of 7R, one from 7S, two from 7T, three from 7U, and one from 7V.
The week number is all over the place, from 25 to 39, and not clear indication of which have the issue and which don't.

7459072:
Out of the 5 such screen reported, two are from 7R, one from 7T, one is refurbished, and one is still unknown.
None of these screens have the negative black issue, and they are all from fairly recent weeks: 31, 34, 37, 38, and 39.

Preliminary conclusions:

There is absolutely no correlation between week number and LCD Panel ID. It seems however that in general, the 5-series are found on earlier weeks than the newest 7459072, but there's no such thing as a cut-off week on either end. This specially doesn't help us identify "good from bad" 7-series screens.

There also does not seem to be a correlation between Factory ID and LCD Panel ID. Most iPhones seem to come from 7R, and this factory also has the largest range of weeks. It does seem that most 5-series are manufactured in 7R (all but one), however there is no clear indication on which 7-series is coming from, which again doesn't help in our search for the golden 7-series.

The only thing we know for sure at this point is that only the 7455232 screens, which unfortunately seem to be the most common ones, exhibit the negative black issue. From my understanding, the 5-series screens are brighter yet more washed out, whereas the "newer" 7451392 and 7459072 screens are perfect...

That's all for now folks, stay tuned for more - assuming we get more entries that is.
Thanks to everyone who has already given out the details of their iPhone for a good cause!

Dean,

What is your brightness set to for the left-hand phone? Mine's set to about 35 - 40pct and mine is closer to the phone on the left, rather than the right.. If I crank it up to 100pct (with autobrightness on), i get closer to the picture on the right...

Does that qualify me as having a negative black image?

Weird, according the Jay-Z picture I have the negative black, but it's not as bad at the picture above, but if I look at the greyscale I'm fine.

Due to the update, you can prolly chalk me up to negative black owners, however it's so minor (I only knew cuz of the Jay-Z picture, the greyscale and other things I've looked at are fine) that I can't be bothered.

They are both set around 50%, or as close as I can tell. Both are also set to auto-brightness.

I do not know if you have a negative black issue, because I didn't know I had one, and still don't know until I put a newer screen next to it.

Given that they both have the same screen ID, I wonder if this means anything...

I had actually noticed it a couple of days ago with some pics I had taken of my dog but I thought it was just a little camera flaw. it's nothing major so I guess I'll just keep what I have now. don't wanna risk the chance of getting a phone that's worse

I'm not so sure about that.
Someone else posted their full serial number earlier and it ended with VR0.

That could be the 4Gb model though, I'll need to ask my friend for his S/N (he has the 4Gb) and find out if it correlates.

Posted by: lidomkj

SN = YM724
LCD = 7455232

I have the negative black issue, have to hold at an angle with brightness set all the way up to see clarity on dark movies or the jay z black album.

I do not have my wife's phone for the serial number, but she has the same LCD, but no issues. Her screen is very clear, brighter than mine. Mine seems to have a blueish tint when compared to hers on bright white backgrounds. Bought both on release day. I do remember when checking her's last night, her serial number had a 724 in it.

Posted by: lidomkj

lcd = 7459072
sn= 7u739

Just got back from the apple store. I had a heck of a time showing them the issue. I had to have my phone and my wife's side by side for them to see what I was referring to. Initially, the genius bar said it was in spec but received a second opinion. Once they saw the screens side by side with the same pictures, they replaced my phone with the numbers above.

Night and day difference!! I do not have the screen set to more than 50% brightness and you can see everything straight on. Perfect screen. I had trouble watching dark movies and this resolved all the problems!

I noticed issues with the negative black, but just thought it was the way the phone was until I started reading more of this issue on this forum.

Thanks to everyone for posting this information or I would not have realized how bad my screen really was.

Posted by: kthankzbye

I had both the 7 and the 5 series. I ordered 2 refurb iphones with series 7's and I noticed one of them was slighty brighter than the other. Both verison started with a 7, not sure if their LCD verison were different or not. One of them had a slight yellowish tint and one had a brigther white (100% on both, auto off). None had the neg issue at all.

My Iphone is still seal in the box.

Ok guys, I checked my friend's 4Gb serial number and it also ended in VR0.
So, it seems WH8 is the 8Gb model, and VR0 is the 4Gb model.

In other news, I got a second replacement (this is now my 3rd iPhone), and it STILL had the "bad" 7-series LCD!!!

And the guys at the Genius bar was a major PITA - I almost didn't get a replacement - and he gave me a refurb instead a of a NIB iPhone, after much arguing back and forth.
So this latest one has a serial number that starts with 5K and is a week 39 - ends in WH8, of course.

Thanks again for all the input guys, I think it's pretty much a shot in the dark at this point to get a "good" screen, from just looking at the serial number...
I'm going to try my luck one more time at another Apple store tomorrow, will keep you posted on the results.

SUCCESS!!!

Just swapped my 3rd iPhone (I guess 4th time is the charm for me) and got a brand new, in the box, beautiful 7459072 screen!
It's a week 38 but the Factory ID is 7V, which is different than my first 2 that were 7R (and both the "bad" 7-series).

So word of advice, if anyone has this negative black issue, keep persisting and get your "good" screen!

(can you tell I'm happy?

)

Thanks again for everyone who contributed to this thread

First, thanks for everyone participating in this thread. It's been REALLY helpful.

It was because of everyone's input that I was able to determine that my first iPhone had an issue with the LCD display. After preforming various tests (similar to this site http://appleservedup.com/ ) i noticed that I was a victim of the dreaded negative black LCD issue. That particular iPhone had the following info:

Serial Number = 7R737...WH8
LCD Panel ID = 7455232

I gathered up my resources, had several links emailed to myself on my Gmail account and prepared for a showdown with an Apple 'Genius.' I went during my lunch hr. to the NYC Apple Store in SoHo. Luckily I only waited 15 minutes for an appointment.

The 'Genius' that took care of my case had a very smug look and bad attitude about him...great i have to deal with a d*ckhead. He checked my iPhone for compliance (i guess checking for hacked or modded firmware) and restored/wiped my phone clean. Then he ran some tests were he determined that the iPhone i had was working correctly according to their standards. I explained that their tests do not test specifically for this issue and because i am a digital artist my eyes were sensitive to these problems.

I explained my case in detail and dropped the phrase 'negative black LCD issue.' That seemed to push a button in his system. He proceeded to tell me that the day before a guy came to him with the same issue. He also explained that he denied his request for a replacement. At this point I already prepared myself for disappointment, but I stayed calm. I knew that I could not argue or muscle with the guy. I tried to be as courteous as possible and chose my words (my ammo) carefully.

Eventually he gave in but tried to stick me a 'restocking fee.' That was total bullsh*t and I wasn't gonna pay for it. I explained that it was within the 14 day period (although it was closer to 21 days) and that it didn't seem fair to have me pay the restocking fee. He went to his supervisor and she allowed him to waive the fee. Somewhere in there I decided to ask for a week 39 production model. I know I know many of you have success with the 38's. But according to my research in various forums, it seemed that week 38 seemed just as 'reliable' as the week 39's. I figured maybe the newer ones had better luck for a good screen. So anyway eventually i got what I asked for. Damn what a HUGE hassle...but at least i got my iPhone replaced.

I went back to my office where i anxiously dialed in the magic numbers to determine my LCD model type. This is what i got:

Serial Number = 7S739...WH8
LCD Panel ID = 7455232

I panicked and thought sh*t...all that trouble and I ended up where I started. I ran the display tests and to my astonishment, no negative black issues on this screen!! I was in disbelief and spent more time looking for more iPhone screen tests on the web. Confirmed...no negative black issue here.

OK...so that was solved. But upon checking and running several more display tests (namely the dead pixel/stuck pixel test) i discovered i had a stuck pixel right smack dab in the middle of the screen. Damn i was annoyed...but this i have seen before...and have successfully fixed. I had a similar problem on my NEC Multisync 1760NX screens at home. What I did with my NEC was to lightly tap the spot with the corner of a standard white envelope. After several taps and attempts eventually i was able to get the pixel to function correctly.

I applied the same principle with my iPhone. I did more research and this stuck pixel phenomena is pretty common. Apparently it happens when the liquid crystal does not spread evenly into the screen matrix. Tapping the area helps to redistribute the liquid crystal and in many cases helps to rejuvenate the stuck pixel.

The force required to 'shock' the pixel back to life was greater than when i fixed my NEC LCDs. I started with light taps and eventually went stronger and stronger till the pixel started to shimmer and flash. Eventually it was able to turn off on a black screen. I saw the stuck pixel a couple more times the same nite I got the new replacement (fri.). i tapped it some more. So far (sat., sun., and now mon.) i have not seen the stuck pixel again.

I will continue to check for the stuck pixel daily. Hopefully like my NEC LCD display that i fixed using the same method it will stay fixed...

...knock on wood...

serial number: 7R739
LCD: 7455232

I have negative black issues

Posted by: blueness

Refurb Serial: 32734 LCD: 7455232 Issues: "negative black," "white dots," light leak at upper left corner (above display area, into black border/earpiece area).

New via Online Store: Serial: 7S738 LCD: 7455232 Issues: "negative black," light leaks in upper left and right corners (most have this but it's really beat, considering Apple, supposedly, prides itself on perfection in quality, design, elegance, etc.)

Apple store: S/N: 7U739 LCD: 7455232 Issues: light leak in upper left and right corners. Not sure on negative black. After checking the LCD number in my car, I walked back into the Apple store (1:45 from my home) and returned it. Fortunately, the woman at the Genius Bar and the manager who handled my return were cool and courteous. The cliche, flamboyant, graying, buzz-cut, Napoleon of a "genius," most into micromanaging the people waiting at the bar, was stereotypically discourteous. C'mon. You help people use Macs in a Mall. This is by no means a position entitling one to a "holier-than-thou" attitude.

Is this my cue to wait for iPhone G2 with 3G (this G stuff is getting ridiculous) or am I destined to hit that store again and hope for a "7-series" other than the lame 7455232? It'd be interesting to know who actually made this LCD. I wonder if any of the folks doing iPhone autopsy sites took note of the LCD panel ID before dismembering their iPhones.

Marc_G: Any new updates regarding the correlation between Factory ID and the LCD Panel ID?

Posted by: Marc_G

Ok guys,

I've recompiled the data with the latest info posted, see attached Excel file.
It is sorted using the following three categories, in order:

LCD Panel ID
Factory ID
Week number

Unfortunately there is no 100% correlation between LCD Panel ID and Factory ID.
The only thing I noticed is that most 7455232 screens that have the negative black issues are from 7R factories, with a couple from 7S.

However there were also two good 7-series from 7R, so there's no guarantee that you'll get a "bad" screen from 7R.
So if I were to take a stab in the dark, I would just avoid 7R and 7S and hope for the best!

-Marc

PS: I'm attaching a ZIP file with the XLS file compressed within, since the original Excel file was too large...

So is the 7459072 screen considered one of (if not the) desirable ones?

It seems to be the latest; or is there a newer one?

Yes, it seems that the 7459072 screen does NOT have the negative black issue, whereas most the 7455232 screens do.
Although more rare, the 7451392 screens do not appear to have the issue either.

As for the 5-series (which I think there's only one kind: 5755136) they don't appear to have the issue either, but are brighter and some claim more "washed out" - could be that it has negative white issue where 2-3 shades of very light gray look white.

BTW thanks for suggesting the Google docs for the Excel spreadsheet, so that other people can view & edit it themselves to add their serial and LCD numbers.
I've added the latest info from other users before this post and placed the Google doc here:

Nice work, Marc.

I agree that your best shot at avoiding negative black is to avoid an 'R' series and something after 38.

I'll try getting an exchange this weekend and post my results.

Posted by: DragonFlyGirl

So just for clarification: if buying an iPhone, ask to see the box first, and try for T, U, V, etc, and week 38+, and it should be 7459072 (or later)?

Posted by: Kadosh

Well, 'should' is such a strong word, let's go with 'could'

From the spreadsheet, seems that the 9072 screens were on week 30 onwards. Seems that 5232 screens are still being used on new iphones because they show up on week 38+ iphones, however almost all those 5232 screens are on 7R & 7S phones. There's hardly much of a correlation going here. Mine is a 7V week 38 5232 screen, and Marc's perfect replacement phone is also a 7V week 38, but has a 9072 screen.

However, DragonFlyGirl, I think watching out for T, U, or V week 38+ has the best chance of getting a non problematic screen. Good luck and let us know how it turns out.

Posted by: Kadosh

Some more meaningless stats:
Good screens before week 36 (just picked a random week) - 60.7%
Good screen on week 37 - 0%
Good screen on week 38 - 50%
Good screen on week 39 - 71.4%

Success rate based on FactoryID:
7R - 47.6%
7S - 40%
7T - 100%
7U - 83.3%
7V - 66.7%

Have a 7455232 LCD
7R732

No negative black issues.

Could someone post pictures comparing a good 7455232 screen with a 7459072?

Posted by: DragonFlyGirl

Stopped in at the AT&T store up the street from me. According to the CSR, all they have are the "old software" phones. had him grab me a box to check it out, and it was a W code, week 39 (7W739 to be specific; I looked thru here, and NO ONE is reporting a 7W.) AFAIK, that *should* have the coveted 7459072 screen, correct? Or is the W (or later) not included in that, and I should specifically look for a T/U/V?

edit: Also, curious: has ANYONE with the 7459072 screen had the neg black issue? Or the white dots problem?

Also curious about the 7459072 screen. Any "negative black?"

Of course, now that it's possible to port the iPhone apps to an iPod Touch, I'm tempted to wait until there's a 3G iPhone. Sure I'll miss the speaker, camera (sure it's 2MP but it's sooo convenient and great for contacts), volume controls and mic (for voice notation when you're not actually using the iPhone as a phone), but I'm willing to wait until Safari feels the same both on and off WiFi/AT&T's network. Otherwise (with regular EDGE), I'd prefer save $20 a month on my AT&T bill and bail on a data plan entirely (just stick to WiFi).

If only Apple would release what we all want and not what they can still sell because the interface is so logical, elegant, beautiful, etc.

PS. Thanks again for creating this thread. It's an excellent resource.

Hmmm...based on the spreadsheet, it seems an overwhelming number of 7455232 screens from the 7R739 batch DO have the neg black issue. Seems to be a crapshoot with the 7455232 screen based on factory code.

Make sure you update the spreadsheet with your info so we can compile more data.

You need to login to your Google account (if you don't have one, create one.) BUT, I think Marc_G needs to allow updating to it, since I don't think I can update it, either. Hopefully he'll see this and change it accordingly.

I'm curious to know if someone has already accessed the "contrast" settings for this phone. We have the brightness settings on the menu but no contrast settings. I believe this negative black issue is just related to the contrast. Anybody?

Ok, managed to exchange for a new iphone while politely explaining the negative black issue. Picked up a 7V week 39 with the 7459072 screen

However, it has the 1.1.1 firmware. Good timing by the hackers.

Did you have the phone longer or less than 14 days?

Posted by: Kadosh

I had the phone for about a month. I had restored it before taking it back. I really lucked out because the apple store was packed and the sales guy didn't really care much to put me in line at the genius bar or verify if the phone was unlocked. I simply showed his the shutdown screen and compared it to a shutdown screen on one of the demo phones. He saw what I meant by negative black and exchanged it for me.

There is. When you first turn it on, slide for emergency calls, type in *3001#12345#* and select call. Select Versions and you will see the firmware version and LCD Panel ID.

Nice, have a 7V wk 39 as well, but I haven't opened it yet. Hope that all from this batch have the 7459072 screens.. If I wasn't OCD I would have just held onto my "no-problem-but-not-perfect" 7R wk 32..

Edit: opened it up and now comparing. I noticed the same thing as DeanFX earlier. My 7455232 doesn't have horrible negative black, but when compared to 7459072, it actually represents colors better. The greens are deeper on the world wallpaper.

The 7459072 on the other hand doesn't exhibit any negative black at all but the colors seem a little off too me, too warm.. Anyone else notice this?

It's a bummer the screen manufacturers aren't all working from the same exacting playbook as full size display manufacturers. I wonder if the 7455232 displays are made by "Westinghouse" (crap) which is really Chi Mei Corp (http://en.wikipedia.org/wiki/Chi_Mei_Optoelectronics).

I've decided to wait on the iPhone and now have a week 39 iPod Touch still in the box/wrapper. It will be a tinker toy until Apple gets its compass fixed (stops cutting corners and insists on quality).

I'll add fieldtest.app to the Touch and see if it will trick the "iPhone without the Phone" to reveal its LCD SN. I have a suspicion that the iPod Touch was rushed to market in a manner that it's suffering just enough of an identity crisis to do just that.

He just got a defected one thats all. The results talks for itself, there was a user working hard to narrow down the panel id, week and serial number to identify which is good and which is bad. Just because that person in the link had one bad 7459072 iPhone doesnt mean its something to worry about

So whats apple doing with their screens right now? Are they still making the two versions? I really liked the 9072 screen, it had no issues whatsoever. But i just got back from the apple store with a brand new 8gb out of the box and the screen has some neg black issues. I thought they would have all been fixed by now. Should I take it back and try for another or are the 9072 impossible to come across now. Any help on this topic would be appreciated

Posted by: jlaw

Looked at all the data collected thus far and decided that the best odds for a 9072 screen were with a V-serial week 39 phone.

Went the Apple Store, talked to a manager, they found one for me... got my 9072 screen.

AWESOME! Picked up 5-series screen with a 7U739 just like someone reported earlier. Much better than the 7459072 i had for 2 days which had color issues, too warm. Look at the home screen with the world wallpaper, and check the bars showing the time. The upper half of that should look like regular gray and not bordering on gray-lavender. The color calibration on those things are way off..

I showed both screens to the Genius and while he wasn't too approving of letting me switch phones just for a screen, he did admit he could see differences. And he showed me his phone as well, which was probably a 5-series. And it was unlocked btw..

Holding onto this baby, as it also beats out my non-negative black 7455232, which beat out the 7459072 in terms of color. No white dot issue.

In short, I've seen all 3 LCD panels and the best out of the bunch is the 5-series, like thadoggfather said earlier. Watch out for color calibration issues on the 7459072! It doesn't mean right away that you got a perfect screen..

I'm on my 3rd iphone. My stuck pixels came back much to my dismay.
First iPhone had the dreaded neg. black.

Anyway, this time I went to the 5th Ave. Apple Store in NYC and had them look at it. The store is great...open 24/365...15 min. walk from my place...

Old iPhone (#2) stats:

I got it swapped for a:

New screen looks great. Nice colors. Contrast levels are fine. No negative black. No dead/stuck pixels. Screen doesn't look 'warm' as some have experienced. Audio is good. Battery life TBD. Remaining cautiously optimistic...is 3rd time a charm?

Serial # written on the outside of the box.

Instructions on the first page of this thread

Posted by: masterchen03

take a look at the serial on the box.
It should read like this: " _ _ _ ##..."
The 4th and 5th digits represent the week of production.

Example:
Serial "7R739..."
39 is the week of production.

Free phones with contract are not worth much when you sell it, phones that are $100 with contract would go for $180-$200 if you sell it

If you go through amazon you can get some good free phones, ie blackberry pearl. Check out the other thread, didn't mean to sidetrack this one.

Oh, and my screen is perfect. No flaws at all.

Posted by: trendx

So how do we know exactly if we have the negative black issue? I went to that apple website and am still a bit unclear. and my serial number starts with 3273945 .. no letters in the beginning like others have.

I am tryin to figure it out by lookin at the jay z album cover but its kinda hard, i donno if mine is a close call or what. But on my ipod album cover it looks horrible, on the website, not so bad. Also can someone tell me why my serial number starts like 3273945, unlike the others?

If you went to the link I posted then you would know what the problem is

Does it say that on the back of your phone next to Serial No.: ?

Yes return it, you have the problem LCD

If your phone doesnt look like the pic on the first post then you have the problem

If you have the problem then to kinda fix it you have to hold it at an angle and that doesnt totally fix it

Serial Number = 7R732
LCD Panel ID = 7455232

However, I don't see any abnormality (negative effect or dead pixels) on it at any angle. It's drop-dead-gorgeous!

I think if it was brand new you would know its new and it wouldnt have a name set to it already

my first post on this forum.

SN 7V738
screen 7455232
still running on 1.0.2 since im not from US.

black issue is also present for me!

but its just a matter on how you look at it (LITERALLY).

and i am convinced now this is NOT a software issue. even though it can be fixed to be less bothering by increasing the brightness a little bit.. (newer firmwares or a 3rd party patch?)

so ... the viewing angle of this screen is somehow limited !
i found this by mistake actually

tilt your 'broken' screen by 10-20 degrees as you look at it.
you will see black issue magicly dissapear

Posted by: I Mod Things

Thats why I feel kinda lucky because I did my research before buying one

It is indeed that simple, that obvious, and that ridiculous (it's the reverse of how an LCD display should behave).

This is still the same on the iPod Touch too. If the market wasn't so flooded with mediocre/defective screens, Apple might have "owned up" to this. Considering the depth of this defect, if they admit to it, they'll have something like the exploding battery issue or Xbox 360 red circle issue on their hands. While I wish Apple or Jobs was cool enough to publicly disclose this issue, bottom line and ego will never allow this to happen without considerable consumer outcry (read: boycott). With a product this irresistable to fans that's just not going to happen.

Aside from AT&T service, the recessed earphone jack, the lack of 3G, and "hit-or-miss" display, everything else about this product is such a leap forward that I might be willing to just accept it as a first gen, live beta. That, or I'll find a discount on an iPod Touch (crappy screen with 1.1.1 workaround and all)and wait for an iPhone with HSDPA?

Sigh.

Got a new phone because of the negtive black issue. Here are my new numbers:

LCD: 7455232
Serial: 7S7390S9WH8

With the new phone, I don't have the negative black issues even though it is the old LCD screen.

LOL thats the best LCD panel you can get

Posted by: Final Light

lol, that's what ive been reading...Tho, i just saw a picture on the phone where as on my old phone it was just negative black, now it you can actually see what it is with some detail. I also watched a little of Smokin' Aces, It does look much better.

I guess i just got used to having a darker[bad] screen...

Just exchanged the phone today because the rubber seal between the screen and the case was coming out. This new one has frozen on me like 10 times today. I think I'm calling in the morning. I was searching to see if this is a known issue after a friend returned hers due to the same issue when I ran across this thread no I don't know whats up yet.

Not sure of the numbers ont he last one.

Really? A very cool Apple Store employee hunted for a 7T week 38+ and came back with a 7T740. I have yet to open it. Fingers crossed that it's not 7455232.

Posted by: blueness

Hot damn! My 7T740 has a 7459072 screen!

Will test for issues once "activated."

Thank you for this post! It gave me all the info I needed to ask the Apple store employee for a specific "first five" that stood a reasonable certainty of having a good LCD. It's funny. I referred to it while at the store and noticed someone else reading it intently while I was waiting for the employee to get my iPhone from the back.
;-)

Posted by: blueness

It's confirmed.
My 7T740 with a 7459072 LCD is not defective. No negative, no dead pixels and no grid.

For the spreadsheet:
My previous iPhone 7U739 from the Apple store had a 7455232 and was returned before I could fully test it but, the initial globe screen did look "off" and appeared to have the issue. (feel free to make the "?" on the spreadsheet a "Y")

The 7U738 I received through Apple as a replacement for a really defective refurb (grid and negative black on a 7455232) also had a 7455232 display with negative black.

I'm happy now but, it took 3 iPhone swaps and an attempt with two iPod Touches (maybe save $100 until iPhone G2?) to finally come back to a 4th iPhone that worked as it should have from my initial Apple order.

I'm sure this will all iron out over time, but, right now, it's clear that Apple is buckling under its popularity and that Steve Jobs, while mellower, might be back to his old T-Rex (tyrant king) ways, behind the scenes.

My previous iPhone with a 7455232 did have the "negative black" effect but, is currently marked with a "?" in that column on the spreadsheet. As did my refurb and one from the Apple store (returned it immediately). I'll hunt down the receipt for that serial number. I believe it was also a 7U739 and it had the 7455232 display.

I havent heard of any 7459072 having the negative black problem

I hadn't either but I figured I'd reconfirm the goodness.

I had heard of a 7T740 that didn't come with the 7459072 I got, though. I almost didn't dare open this one. I'm glad I did. The iPhone is such a sweet marriage of an excellent hardware interface with a very logical software inteface.

Under my IT consultant hat (as opposed to my 3D visualization hat), I administrate a number of Treo 650s and 750s. The Palm OS and Windows Mobile OS get the job done but, not well. Then there are the displays! Even a "negative black" iPhone has a far better display than either the 650 or 750.

Posted by: not_too_shabby

So just to confirm if I get a 7T740 it's very likely I'll get a good screen?

I dont think any serial number can guarantee a 7459072 lcd panel

Posted by: xjust

there is no way to ask apple for that specific panel when ordering a phone ?

Even they dont know what phone has what panel, we have a qlue about what serial number but thats not guaranteed

Basically theres no way to tell exactly unless they start making phones that all have the same panel

every single week 40 phone i've seen has the 7459072 lcd panel.

7U738T serial

7455232 screen

confirmed negative black

Had to argue with the damn apple genius that it really was defective. He tried to tell me no it wasn't, so I asked to speak to the manager. He came back and told me they would replace it because "I felt so strongly about it" and handed me a refurb. It has the old 5 series screen and looks good, but it pisses me off that I purposely paid for a new phone and got handed a refurb when I could have bought a refurb online for less. My phone was only a day old btw. So far, my first dealings with apple are coming in sub-par.

Posted by: HelioPause

You should NEVER have let them give you a refurb. Especially if your phone is one day old. I would have pitched a fit.

Posted by: Mini Viper

Judging by the way things were going I was lucky to walk out with a replacement. You think if I go back they would give me a new one, is it worth it...damn. ****ing Apple Store in the Galleria in Houston is a mad house.

Is it worth complaining to apple about the poor treatment I received? I really feel like I got screwed today over a legitimate issue.

Posted by: Mini Viper

Went back in, talked to manager, walked out with new week 42 iphone. Apple just won some points back.

7455232 display

I just got on this site so not sure what the issue with the screen is (going to search now) but I havent had any complaints about it.

EDIT: I just looked at the Jay-Z Black Album cover as someone suggested in another thread and I could make out the face on it which seems to suggest that mine does not have the problem.

Good your lucky but check here

The first pic is not what you want yours to look like (look at your iPhone straight on top not an angle)

Serial Number = 7R735
LCD Panel ID = 7455232

Have no clue if mine has a negative black screen

Edit

When looking at an image of the Black Album on wide screen internet, it looks fine, but when looking at the image normally it looks like a hologram.

So i think i have the issues, but if mine is jail broken, should I restore it and try to warranty the phone?

So it sounds like the best action would be to avoid anything week 39 and earlier. Perhaps Apple nixed the 7455232 screen by week 40. I'm very happy with my 7T740 iPhone and am happy I was patient (3 iPhones and 3 iPod Touches patient).

Now I have to help a client with a dead pixel on a Treo 750. Sigh. Is all Chinese manufacturing crap? Then again, would "Made in USA" be much better?

Interesting.

Maybe they finally fixed the AR coating at that manufacturing facility. What were the first three digits of the serial numbers on those week 44's?
