C5, C7 ?

I've send my Galaxy Nexus to my reseller, which has send it to Samsung in order to change my screen (with a ghost image, burn in effect).

I've received my phone with a new screen :)

But how can i know if it's a C5 made in China or a C7, or another... ?

I haven't any document after the repair.

Thanks and sorry for my poor english...
[Samsung Galaxy Nexus] chrone:
Right on! Enjoy your Nexus while it's hot. :D

Feels like been a lucky draw to have near perfect display on Nexus these days. Never give up and make Samsung pays for the replacement devices or screens. Bwahahaha...

But How can i know if it's a C5 screen or not ?

EDIT : It's C2 on the battery, but what is the link between battery and screen ?
[Samsung Galaxy Nexus] chrone:
You should the fourth and fifth characters on the serial number inside the phone right where you place the battery. The battery serial number doesn't count.

My purchased gnex was C2, the 1st and 2nd replacement came with C5. I picked the 1st C5 since it has no purple tint, only slight banding and textures on white background and slight banding major textures on mid-dark gray backgrounds at low brightness, even at 100% brightness the textures on mid-dark gray are still there.

I noticed one person in this thread couple pages before has C7 batch and has no major issues. The black spots on pure black background in very dark ambient lightning are still spotted though.

So it's been like a lucky draw so far. *sigh:/

[Samsung Galaxy Nexus] vince451:
OK Thanks, but i've not any C... in the Serial Number wher i place the Battery.

the 4th and 5th are "B" and "B"...

My new screen seems good (because it's new...), and i hope he'll stay like that !
[Samsung Galaxy Nexus] chrone:
The B is for GNex made in 2011, while the C is for 2012 production. I forgot what's the fifth code for 2011 production, but the fifth code for 2012 is the number of the month. As I recall the 2011 fifth code for months began with alphabetic and not numeric.

C2 2012 Feb

C5 2012 May

C6 2012 Jun

C7 2012 Jul

hope you get the 2011 made in Korea. most GNex made in Korea are having bigger rate to get perfect screen. :)
[Samsung Galaxy Nexus] vince451:
OK, i know that my GN was made in 2011 but i don't know about the new screen...

It looks like a hexadecimal number : BB = 2011 November.

I've bought my phone in December 2011.

But I don't know how to know which screen he has now...
[Samsung Galaxy Nexus] chrisjs81:
That's very fast turnaround, I'm a bit confused. You bought the phone 3 days ago, sent it to Samsung for repair and they replaced the LCD itself, or did they just exchange the phone? Also, where did you have it repaired, Samsung in the US? Thanks
[Samsung Galaxy Nexus] chrone:
oh the lcd batch, that's a different story. LOL. still don't know how to look the lcd batch though. :P

i also wonder if any gsm hardware revision 10 is a good batch for the screen, does it hardware revision fix the screen or other area in the phone?

all three of mine were hardware revision 9, made in China.

i guess he only replace the lcd at samsung service center. i dunno whether lcd replacement in USA has better lcd batch, but in Indonesia, the lcd are all made in China and they all have still have slightly purple/blue tint, banding, textures, and black spots are still there too, but better than the first purchased one.
[Samsung Galaxy Nexus] chupzz:
They replaced the LCD. I'm in Indonesia.

In Indonesia, if you have already past one day from date of purchase, you have to go to repair centre for service. but they fix it very fast, they give 1 hour warranty for replacing all parts of your phone.
[Samsung Galaxy Nexus] sblantipodi:
Today I got a second nexus.

Two phone two completely different display.

The grey tones are completely different between the two phones.
[Samsung Galaxy Nexus] j3r3myp:
I think mine's C1. No country so made in Korea but not sure either.

What issues are reported with C1, except the black dots that I have but not really important, only two or three.

I have tweaked the screen colors with Franco Kernel app so I don't remember if it had a purple tint.

Should I ask for exchange to a C6 ?
[Samsung Galaxy Nexus] natzy85:
Hello guys,

I need your professional skills to help me in the following situation. I bought a I9250 from a guy in the summer. It was in the light of the day and I could not see that the screen had a problem. When I got home I noticed that the upper part of the screen was faded. It was not such a big thing but in the following weeks the screen went from not ok to unusable. I noticed that after charged overnight the screen got worse and now I don't have pixels only at the bottom. I have black were the pixels needed to be.The battery is not original it is a 2000 one. Could it be that the battery broke the pixels? The touchscreen is still working were I don't have pixels thought.

It is very expensive for me to buy a new screen so I found a guy that would sell his screen to me at a good price. The only downside is that the glass from his screen is broken. Mine is good. Is there someone that knows if it's a good thing to buy the screen with the broken glass and then ask a phone service to do the switch? I searched the net and starting July you can buy only the glass and replace it just like in the case of Iphone. So for the people with broken glass they don't need to change the hole screen. I am thinking also to change the battery with an original one and I hope it will not put in danger the other display. What do you guys think? Thank you for your time to read all of this :)
[Samsung Galaxy Nexus] chrone:
Don't! If it's made in Samsung then it's made in Korea. You have a very nice screen there. Almost everyone i know have black spot, so leave it alone.

Update: someone just corrected me that made in Samsung is not made in Korea.

The 2000mah is the official extended battery from samsung, so it won't damage your screen in normal use.

It seems that your screen was used heavily outside its operating limit by the previous owner, perhaps s/he turned all the brightness up to maximum all the time non-stop, or setting gamma too high from a custom kernel or rom, and such.

Am sorry for your screen, but IMHO, there's no other way than go to service center and claim it warranty if there's any. Good luck, dude!

[Samsung Galaxy Nexus] natzy85:
sorry it's 1900 mAh and 3.7 VDC. it only says replacement for i9250. Made in China.

You are saying that not the battery was the issue right? So I won't have to buy the original. No warranty it seems that I will have to pay 161 euros for a new display. Anyway, thank you very much for the info. It is very annoying that we have to pay so much for just a display. I have looked for Iphone 4 out of curiosity and an original display is just 66 euros. Also every service in the world can change the glass. It is a shame that we have to pay more just for the fact that we love Android and not IOS.
[Samsung Galaxy Nexus] kms108:
Sometime you can't blame the quality of the screen, it depends on how you use it, the life span of the screen should out last the usablilty of the phone, i've used lots of samsung phones and many of them with amoled screen, never had problems with normal use or just set to auto.

And you cannot compare the prices of spare part with a different brand phone, they are not the same. With iphone the screen, digitizer and lcd are individually sold and assembled, whiles the amoled is all 3 in one and must be replaced as one, even the service center will replace the whole part together.
[Samsung Galaxy Nexus] natzy85:
agree with you but why can we buy just the glass? look at this link:

http://www.xphoneparts.com/china-wh...ront-glass-outter-lens-replacement_p3909.html
[Samsung Galaxy Nexus] kms108:
Those aren't suppose to be available, they were mean't for manufacturing the full screen unit before sold as spare part, you can get them even from china, but you wont be able to use them.

---------- Post added at 01:31 PM ---------- Previous post was at 01:28 PM ----------

try finding someone who sells just the glass, and ask them you will pay them to fix it on the phone, i'm sure they will just reject you, they dont have the equipment to put them together.
[Samsung Galaxy Nexus] natzy85:
thank you for the quick answer. I will buy the replacement display. What about the battery? Is it ok to leave the current battery or should I also purchase the original one?
[Samsung Galaxy Nexus] kms108:
You phone is exactly cheap, so purchase original stuff to prevent any damage.
[Samsung Galaxy Nexus] darkvice01:
I got my 3rd LCD display replacement and all of them are having purple screen and retention. Manager in service center were polite to ask Samsung headquarters to ask Korea made LCD or get LCD in a different supplier..
[Samsung Galaxy Nexus] chrone:
Same here, I'm waiting for the Korean's screen they promised me after my complaints email to Samsung Korea, Hong Kong, China, USA, and Indonesia. Only Samsung USA responded me well and promised to take care these thing, afterward a call from Indonesia office made sure that they will look to import the screen replacement from Samsung Korea and let me know when the LCD arrives.

Good luck to both of us! :cowboy:
[Samsung Galaxy Nexus] mkouk:
I have sent my Galaxy Nexus for the second time now to Samsung (see Intercity Telecom, one of their UK Service Centres) and waiting to see whether they will provide a good quality screen replacement this time round. :fingers-crossed:
[Samsung Galaxy Nexus] darkvice01:
I'm so getting LG optimus g or no bezel Motorola as long its not HD super amoled or super amoled plus. Or I'll get padfone I'll just wait til January if Asus will release new padfone next year march.

the no bezel motorola looks good, hope it comes with AOSP and not bloated vendor customized OS. :D
[Samsung Galaxy Nexus] thecresta:
On my 2nd Nexus. The top half of the screen is darker with a red tint. Noticeable at any brightness level, very noticeable below 50%.

First one had a yellow tint in the top left, a blue 'bar' down the entire right hand side, and a red tint at the bottom.

Feel like this is going to be a long journey...
[Samsung Galaxy Nexus] chrone:
never give up and good luck, dude! :)
[Samsung Galaxy Nexus] thecresta:
Thanks for the support :)

I love everything about this phone - size, shape, build quality, stock OS, lack of branding, etc, but the screen is a real let down.

I'm quite finicky when it comes to screen reproduction, and going by the experiences of others the chances are I'll never be happy with it. This is made worse by the fact that I'm now going out of my way to look for problems.

Seriously considering the fate of my next replacement...
[Samsung Galaxy Nexus] chrone:
Same here, despite it lacks am/fm radio, my real complaint is with the screen quality, really not super. Hahaha :D

The screen defects really hinder this phone full potential as the nexus flagship phone.

Overall, love the buttery smooth performance. Worth the wait for the screen replacement. :D

The lovely thing on nexus line is it is the most supported device by developers, so once am bored with vannila UI, i could always flash it with tons of custom ROMs.

does anyone know how to fix the purple tint issue ? honestly i haven't buy the gnex yet & i want it, but the purple tint issue is really bothering me, i have already search it in google and xda and i haven't found it yet

shame on you, samsung

hey are you "Chrone" from an indonesian forum "Kaskus" ? member.php?u=4773

your avatar is same with your kaskus id :)
[Samsung Galaxy Nexus] kms108:
2 options

keep the screen turned off, so you will never see it.:fingers-crossed:

change the screen.:fingers-crossed:
[Samsung Galaxy Nexus] ReAlives:
LOL :laugh: great solution, you could still use it for door wedge :=D
[Samsung Galaxy Nexus] chrone:
yeah it's me :D

just claim your replacement warranty from the local store, and make sure you get the best screen the store has to offer. i believe the store only has twice replacement policy, thus if things don't fall into places, pick the best one, and go to samsung service center indonesia to claim another screen replacement, and make sure you also get the best possible screen you can get. do the screen replacement claim every now and then until you get the best possible screen you can live with.

you could always use custom kernel trinity/franco or so on to minimize the purple tint though. but as for me, i always prefer the stock pure Google experience. :)

am still waiting for my screen replacement, they promised me to replace it with the screen which is made in Korea and or keep import another one from all samsung factories until i get the best screen they have to offer. *finger crossed*
[Samsung Galaxy Nexus] sblantipodi:
gray stripes are visible on gray and on white screen also at 100% brightness.

never more a crappy phone like this.

A quick pic of my current GNex screen, taken from my trusty old SGS i9000.

The picture quality is terrible, but it highlights the problem quite well.

Dark with purple tint in the top half, gradually getting lighter towards the bottom.

Also a faint blue horizontal band near the middle of the screen, and vertical lines from top to bottom (can't make them out too well on this pic).

Here's the grey test pic I used. Seems to be just the right shade of grey to highlight all screen defects:

Using my original SGS has reminded me of how a SAMOLED should look. The image quality is superb. The same grey pic looks solid and bright by comparison.
[Samsung Galaxy Nexus] darkvice01:
Bad news came.. Samsung main in the Philippines said that its impossible to get LCD made in Korea nor LCD from different supplier they ask me to surrender the phone so that their tech in main office will check it, if its really faulty they will replace it.but one thing is for sure knowing big companies here will find away to say its normal which I expect. Let's hope that they replace it if not I'll take this to the court and spread this in media as well. Just stay tuned.
[Samsung Galaxy Nexus] alangrig:
Don't try to get screen made in Korea. Mine phone made in China and its gorgeous in all departments. Just claim new great screen. Today, finally I gonna get DSLR and take some pictures of the screen. My GN made in China, it's clearly stated under the battery Made in China by Samsung, production batch C7-July 2012.

This is the best GN i've seen from 50 observed units.
[Samsung Galaxy Nexus] chrone:
Let's hope for the best here. For USD 349-450 spent on this device, we should get a perfect display.

Yeah, it doesn't matter where the screen is made as long as it works as advertised. But only 1 perfect screen out of 50 units that is quite low for samsung's standard. It should be 1 defect screen out of 50. Hehe

Btw, the batch on battery is not the phone's batch production. Could you please take a look the batch code inside the phone where you place the battery inside? Mine was C5 though the battery was C2.

Can you take picture of your LCD we need it to compare.

Definitely I'll do this weekend. Gonna get today DSLR.

wow are you saying that you will sue samsung for making a low quality display for gnex ? okay then...all eyes on you :fingers-crossed:
[Samsung Galaxy Nexus] sblantipodi:
this image shows me all the banding issues of my nexus, what a crappy display.
[Samsung Galaxy Nexus] alangrig:
So far i was able to take some pictures just to show that gamma is adjusted properly from the factory and now purple. I gonna get proper DSLR to make proper shooting in order to show no graininess and no banding.

P. S. Attached photos are dirty one, so don't pay attention to it.

In terms of purple issue all photos were captured at 0% brightness. Black saturation Gamma at 50%.
[Samsung Galaxy Nexus] TSGM:
Can I ask you how did you get the second picture (was it a website, a program, an image?). I tried going back through the thread to see if it was mentioned, but there are about 130 pages...

Is there any way to adjust your color hues/gamma/contrast while viewing a good set of reference pictures (like the one on your right)? I'm currently using the Trinity Kernel, but it's hard to see the effects of changing different options.
[Samsung Galaxy Nexus] alangrig:
I use Display Tester apk from Google Play Store https://play.google.com/store/apps/details?id=com.gombosdev.displaytester&feature=search_result#?t=W251bGwsMSwyLDEsImNvbS5nb21ib3NkZXYuZGlzcGxheXRlc3RlciJd

There is section "Gamma" in Display Tester apk, choose black saturation test. You can adjust all hues/gamma/contrast by installing custom kernels: Trinity or Franco.

However I prefer pure stock,'cause I can't spend to much time for customization - quiet busy. So mine pictures where taken from pure Jeally Bean Stock Takju version.

In order to attempt serious color adjustment in other words to bring them to standard in accordance with benchmarks, you can use HCFR software just google for it, but make sure you need additional hardware.
[Samsung Galaxy Nexus] darkvice01:
Law in the Philippines is not so much different from US so its definitely Yes, if they will not replace my LCD w/ no issues, we all deserve to have this phone w/ no experience of inconvenience or dissatisfaction.

[Samsung Galaxy Nexus] sblantipodi:
do you mean that GNEX has two different kind of displays?
[Samsung Galaxy Nexus] chrone:
No, gnex uses only hd samoled, while other old phone of samsung galaxy series some use samoled and samoled plus. Samoled has smaller screen size than hd samoled, less ppi, better quality.

As far as i've known, only samsung galaxy note, galaxy notes 2, and samsung galaxy s3 use hd samoled but with more superior quality than the one on gnex.

Sorry for the confusion i have caused. :)

update:

Samsung Indonesia just called me this evening following up the complaint email i sent 3 weeks ago to Samsung USA, my screen replacement has arrived, but i can only go to them on saturday. they said they've tested it well, yay! :D *finger crossed*

another suprise is that running gnex this last two months, i can confirm that now my screen has officially has horizontal stripes on Red, Blue, and Gray. :( i just found it out when using adobe reader app, the red background on the adobe logo full screen mode was somehow had funny looking due to the horizontal stripes, i thought it was adobe's red theme with stripes. then i ran display tester. by setting the brightness of dead pixel test to 1% and 10% confirmed the horizontal stripes which i didn't have at all at first place.

what a poor quality display this recent batch gnex has. i used auto brightness almost all the time and i'm sure i use it 90% indoor with low room ambient lightning. hope the screen replacement won't suffer the same fate. *sigh :(
[Samsung Galaxy Nexus] PizzaAmerican23:
screw this thread.

I originally had a feeling that my screen looked off (low brightness looked pretty bad, especially when the screen was grey in the market) I also saw some blotches on my screen when its completely back and the room is dark (same way on my old phones though, so no big deal)

I originally thought it was a problem, but now after seeing this, i cant unsee it, and i know its gonna bother me now. Hopefully after a few days ill forget about it and go back to being happy with it. It really only is noticeable in some situations (low brightness and dark room) but really isnt a huge deal i guess.

My 2 most important things are: White text on black background reading - looks fine to me. And i play video games on it a ton, and those also look very good.

[Samsung Galaxy Nexus] MkVsTheWorld:
I'm also experiencing the Image Retention Issue, aka the previous screen lingering on other screens. Has anyone else continued to have the Image Retention problem after warranty replacements?

I just bought my phone from Google Play last week and I contacted their support about it and they told me that it was up to my discretion to get a replacement since I had some other problems. A factory reset and later a cache reset resolved my issues so the Image Retention is the only thing that appears to be troublesome. So, I'm on the fence about getting a replacement because some people say it's normal and some people say it's not. Google Support told me it's normal but also said because of the other problems I had, I can get a new one.
