[Samsung Galaxy Nexus] Formhault:
I wanted to flash the stock ROM to see if the screen acts the same... Pretty retarded of me, since I knew I did any settings I could and the gray still turned purple and stuff...

Anyway, flashing the stock ROM image formatted my SDcard, and now I've lost the photos I made at seaside, apps/games .apk files, my Titanium Backup (including my Opera Mini with ~100 articles saved :):):):):):) )... F*** !

Since I was at that point anyway, I flashed the stock recovery & re-locked the bootloader. Then went straight to the warranty serice and told that girl everything about the screen. She said the phone will have to go into the labs for investigation... I'm very curious to see what they'll tell me when it gets back : "no problems detected, everything's OK, service not needed". If that's going to happen, I'll set the screen to the maximum brightness and leave it on 24/7 :) . Then, when burn-ins begin to take place, I'll return.

Anyway... let's see how it goes...

The service I went with my phone to isn't Vodafone. Vodafone told me to go to CIRMA / CORDON ELECTRONICS. I hear that firm is pretty much international, so chances are you heard of it, too (they suck, fyi).

The One X has that (hardware) Wi-Fi issue... Plus, the screen is too tensed - try to squeeze it by the sides = see the plasma flow :eek:

Other than that, it's a great phone. Expensive, though...

Image Retention

Been lurking for a few weeks and finally pulled the trigger on the Galaxy Nexus last week. I've been all iPhone for the past few years and this is my first experience with Android as well as AMOLED technology.

I noticed this within the first few minutes of use...

i456.photobucket.com/albums/qq284/dupl1cate/7a6ba433.jpg

(The board wouldn't let me post an image. I'm new. :rolleyes: )

This is image retention according to the first post. Should I exchange it? How common is this? I don't want to exchange if there's a 90% chance the new one will have it. I'd rather return it if that's the case.
[Samsung Galaxy Nexus] zetsumeikuro:
Love the phone but I wish the screen was a bit better. I think I need to contact warranty to have another Nexus sent out to me. I notice it w/ a red backround or while watching netflix/any videos. Like a bunch of tiny lines running across the screen its pretty bad. It's supposed to be a smooth color but I can see a bunch of hairline thick black lines.
[Samsung Galaxy Nexus] Formhault:
OH MY GOD !

Mine didn't have it. At least not THAT ugly... and not with the icons.

Ask for a replacement.

That's called banding. Ask for a replacement or a refund if you can.
[Samsung Galaxy Nexus] zetsumeikuro:
It's worse than the regular banding. It doesn't even vanish when I set the phone up to higher brigthness.

Here it is.. Just take the glare into consideration. The curved lines aren't there and only show up in picture gg glare. The fine black lines are present though always on red backrounds, and in videos in some scenes etc.

I have this issue but only when having whats app open for about 2-3 minutes (white/green text boxes on black background) and then exiting to the homescreen (blue background). I'll see the message boxes for a few minutes. I can quicken the process of getting back to normal by opening the drawer a few times and playing with the screens brightness.

It gets stronger when whatsapp stays open for longer than 2-3 minutes.

My phone is about 3 months old, do you think that's a reason for returning it for repair?
[Samsung Galaxy Nexus] Formhault:
Warranty - take advantage of it !

---------- Post added at 09:25 PM ---------- Previous post was at 09:24 PM ----------

It is young (3 months old), so it's definetly a faulty hardware. Mine is 6 months old and the problems I was having with it are MINOR compared to those you are having.

-----

Hey, this is for both of you, zetsumeikuro and bragih. When you set the brightness to loweest, does the gray color turn purple?
[Samsung Galaxy Nexus] bragih:
No, at least not on my blue background. it's still grey or at least a darker blue than the blue sorrounding the boxes.
[Samsung Galaxy Nexus] Formhault:
The settings menu or the pop-up for the screen brightness settings are the best place to look for purple tint. When you turn down the screen brightness, see if the gray background of the pop-up goes purple... I know mine did... and I was not the only one...
[Samsung Galaxy Nexus] bragih:
They're casting shadows on the grey background.
[Samsung Galaxy Nexus] Formhault:
What?
[Samsung Galaxy Nexus] bragih:
They're there on grey background but they don't change their color. :o
[Samsung Galaxy Nexus] Formhault:
Explain...

What's casting shadows? The icons? == image retention / ghost image?
[Samsung Galaxy Nexus] zetsumeikuro:
Pretty much. Nexus #4 or 5 here I come! No my greys don't turn purple.
[Samsung Galaxy Nexus] danilow_16:
too bad:(

I was wondering to buy from amazon and ask to deliver in my girlfriend´s hotel while she´s in Orlando, but after these all issues, do you have a recomendation because in brazil the gnex is really expensive, when in amazon i found at USD 440, in brazil i found at USD 700, this problems are common ore rare, or this is resolved?

i´m planing to buy this in 13th july to be exact

I will have no warranty if i buy from US so I have to take double care

thanks

what do you think??

I´m wondering too if there is any diference between the US and Brasil too?

my girlfriend won´t be able to see if the phone is ok or not, just me when she´s back here and so...
[Samsung Galaxy Nexus] TZAR@:
I am so over Amoled screens!!

I used to be a big fan of the Amoled screens. Not so much now. When I look at the Galaxy Nexus's screen compared to my girlfriends HTC One S screen, her screen has whiter whites, it's brighter and seems to generaly be more crisp. I love the deep blacks of Amoled screens as well as the way the colors {POP} but where I draw the line is the artifacts left on the screen. I have terrible screen burn in or ghosting or whatever it's referred to as. I even noticed a small circle in the upper left quadrant of the screen that I have no Idea of how it got there. I think it's right above the CPU and was caused by heat (speculation). And the pinkish/yellowish hue is getting on my nerves. I have it set to full brightness so the banding isn't an issue but I sure hope that the next Nexus phone has an SLCD2 or better screen. Man woah! I never thought I'd say that I'd rather have a SLCD2 screen rather than an Amoled one. But the cons are beginning to outweigh the pros of what I used to like about Amoled screens. I'd take it all back SAMSUNG if you fix these issues in the next line of Amoled screens you produce. Otherwise I'll take a HTC made Nexus please ;)
[Samsung Galaxy Nexus] Formhault:
I have that circle in the upper-left, too :) . It's visible on dark grays, but you can see it if you struggle on whites, too. I just hope the screen replacement that's going to come through (HOPEFULLY)... will fix it.

The One S also has a Super AMOLED. It's PenTile, too :) . I've seen it and the phone is great overall...

I WISH I HAD A SLCD2 :) .
[Samsung Galaxy Nexus] gaara.awp:
To all those who are having purple tint issues

I had purple tint issues as well but its gone after i installed trinity kernel. the screen is amazing now. it does not solve the grainy display issue though. the default color settings "the spice melange" is really good. there's a slider to decrease (or rather bump) the contrawst to -24 which really improves the quality of screen. this option is different from omap gamma thing.

try and see if it solves the issues.
[Samsung Galaxy Nexus] Formhault:
AOKP Build 39 includes Device Settings, which has more profiles for screen color... You can set it in such way so that the grays don't become purple when set on low brightness, but if you set the brightness to the max, the grays tend to become somewhat greenish, and the overall sharpness of the colors starts to feint ;) .

There are compromises everywhere :(
[Samsung Galaxy Nexus] kms108:
I would be apprieciate it if someone can help me check somethink out.

on my gnex the very first line (left to right) whiles in vertical position or first line (top to bottom) whiles in horizontal, is the line a lighter colour.

I am on default stock rom 4.0.2 non modded.

you can see it very clear using the app below in the darkest grey setting.

[Samsung Galaxy Nexus] kms108:
It's very hard to take photo's, if you cannot see anything, it must be mine.

I'm deciding whether to trade it for a GS3, i've got a high price for it, but I like the three main buttons on the gnex, they react much faster than the GS3 main buttons.

the GS3 has a much better quality display, probably because of the problem with the gnex, so they put more effort on the GS3 and it's also the flagship of the galaxy range.
[Samsung Galaxy Nexus] jediman:
Posting mine. This normal?
[Samsung Galaxy Nexus] Matt08642:
That's a screenshot, so we can't really see if you're having hardware issues lol
[Samsung Galaxy Nexus] Formhault:
If you ask me, I'd say hardware buttons are faster than the on-screen ones of the GNex... Oh well...

The S3 did look dimmer at stores, but I think yeah, Sammy must've optimised their SAMOLED PenTile technology :) . Anyway, I'll see if in one month it becomes burned; the S3's I've seen have the Samsung demo on all the time, so... :)

---------- Post added at 08:25 AM ---------- Previous post was at 08:24 AM ----------

Looks fine to me... because it's a SCREENSHOT, like Matt said. Take a picture of the screen, with another phone / camera (not a crappy one, lol).
[Samsung Galaxy Nexus] jediman:
Yup my bad guys. That's what I get for posting late at night. Images later.
[Samsung Galaxy Nexus] Razer(x):
No workaround for the ghosting issue, am i right?
[Samsung Galaxy Nexus] Formhault:
Nope... sorry... It's just no way you can fix it through any software modifications.

I should get my screen replacement anytime soon (either tomorrow, either the day after, either in the following 10 days :) ), will keep you up to date with that... I really hope I get the replacement - otherwise I don't get why it's taking them so long. Hope the new one (if there is a new one) is 100% fine :)

On a side note... FML :)
[Samsung Galaxy Nexus] fire & ice:
I had the same issues with the screen. I refunded and bought a complete new one within the 14 days from the google play store. The new one looked 100x better.
[Samsung Galaxy Nexus] Smokeey:
I got the ghosting issue. Called Verizon who instantly offered me a replacement GN and took it, should be here tomorrow. Hopefully this new one is flawless.

[Samsung Galaxy Nexus] jmattp:
I think every Galaxy Nexus purchased within the last few months will have all of these issues. I personally have seen about 20 devices since I sold the good one I posted pictures of many pages back (still regret it... I didn't know it would be this widespread of an issue).

Two days ago I looked through five phones, today I bought one. All had purple tint. Samsung doesn't give a **** at all.
[Samsung Galaxy Nexus] Hinouchi:
How long did you leave the screen when that happen?
[Samsung Galaxy Nexus] jmattp:
Yeah... Trinity kernel fixes the color 99%. I flashed it over CM9 and was so relieved to see it look so... normal
[Samsung Galaxy Nexus] zetsumeikuro:
It can go away if it's ghosting over time. Play some videos etc, leave on a white screen w/ full brigthness. I found after I did that the keyboard ghosting vanished for me. If it's amoled fatigue/permanent image retention or as people call it "burn in" eventhough it's not really burn in. Then you need a replacement screen at this point.
[Samsung Galaxy Nexus] gaara.awp:
Yup, trinity kernel fixed all the color issues for me as well (except the grainy whites- guess thats a hardware issue and cant be corrected with kernel tweaks). trinity colours ftw !
[Samsung Galaxy Nexus] Formhault:
Displaying a full white color would reduce the maximum brightness of the screen :) . Which one would you rather have, reduced screen light intensity, or ghosting?

---------- Post added at 08:33 AM ---------- Previous post was at 08:31 AM ----------

The keyboard "ghosts" like that for me, too. But it vanishes after a couple of seconds... and it's not that visible.

---------- Post added at 08:34 AM ---------- Previous post was at 08:33 AM ----------

Lines all over the screen come not only from the keyboard, but from the pop-ups and the general menu... For example the blue line in Settings, the one that separates "Settings" text from the actual menu...

---------- Post added at 08:35 AM ---------- Previous post was at 08:34 AM ----------

Really? It makes gray look gray even when the brightness is low? How about on maximum brightness? Don't they (grays) become green`ish?
[Samsung Galaxy Nexus] ph0b0z:
I'd like to see some comparable pictures of this, at different brightness-settings and with display tester on! ;)

I kind of doubt that this can be done with one setting for all brightness-settings.

I think for the Galaxy S, Supercurio/Voodoo Mod he used a Colorimeter to calibrate the colors in and this was done for multiple brightness-settings if i remember right.

Apart from that, on my Galaxy S i liked the Cyanogenmod-Colors the most, since they looked the most natural.

Would be really interesting to hear from someone who really knows where the cause for this problem is, since my developement-skills are limited to very little java. :P

Anyways.. still waiting for the german suppliers to get new Galaxy Nexus's! Or Nexii..? :)
[Samsung Galaxy Nexus] Formhault:
Calibrating the colors on a faulty AMOLED screen would fix in some places and break in others...

Nexii?! :confused:
[Samsung Galaxy Nexus] jmattp:
I haven't noticed anything look greenish. When I made my own adjustments using the built-in CM9 color adjustments before flashing Trinity, I did notice more greens when I lowered red and/or blue.

When I started from scratch and flashed Trinity, colors looked almost perfect. At 100% low brightness, you get a little purple on the pop-up menus (like the brightness slider in Settings). But I much prefer having a little purple on that one thing during extremely low brightness settings (which I never use because the system doesn't drop that low when set to automatic brightness) than purple everywhere like it was before. The black-to-gray background image used in Settings and some other screens (background_holo_dark.png) is black and gray, no longer purple. Also, the notification tray is actually black like it should be.

I mean, that's on my phone. It might not be exactly the same on yours, but it's worth a try.
[Samsung Galaxy Nexus] gaara.awp:
This, yes.
[Samsung Galaxy Nexus] Formhault:
Hmm... guess I'll give that a try on my phone - when it comes back from service, which will happen tomorrow (that's for sure now). If the screen replacement (if any) is still purple-tinted... I'll give Trinity a shot.
[Samsung Galaxy Nexus] osm0sis:
Ugh yeah I got mine back from service. Re-sent it twice and they still refused to see the purple (which I have even at 100% brightness!) as an issue... Stupid Telus. I guess I'll give Trinity a shot first, then Franco if that doesn't work so I can tweak out the color profiles. Do Trinity/Franco kernels break anything from the stock experience? NFC for example?
[Samsung Galaxy Nexus] zaneburton:
So far, I've had four brand new in box replacements that all had the purple display issue and the image retention/ghosting problem. When I called to ask for a fifth, the customer service representative suggested that we just try to get one of the phones that I still had repaired, instead of sending another my way that just had another defect. Sounded like a good plan. I received that phone today. It still had the ghosting issue, and the lcd discoloration to purple. This is despite the fact that the tech who replaced my display had SPECIFIC INSTRUCTIONS to check for both of those issues before they sent me a replacement. Was the tech blind? Did he not read the instructions? I'm not even sure what I'm supposed to do at this point.
[Samsung Galaxy Nexus] ÜBER™:
My keyboard retention is getting worse. Not going away now and is faintly visible on gray backgrounds. Looks like I'll need a replacement soon. :(:(

Sent From My Sprint Galaxy Nexus
[Samsung Galaxy Nexus] gaara.awp:
No, they don't break anything. They work perfectly. Flash one of their stable builds (trinity) or milestones (franco) and you are good to go. Their nightly/ experimental builds are also very good as well.

I suggest Trinity. Their colours are amazing. Franco has omap gamma slider which only makes matters worse at certain (low) brightness. Apparently, changing gamma fixes the brightness at some levels but screws it at other levels. I believe, if you have their app, you can change the color settings. Use the following colors:

contrast: -24

gamma: 0 for r,g,b

multipliers

red: 135

green: 135

blue: 214.

Or if you flash the zip in recovery, these settings are set by default.

At first these settings may seem too bluish but trust me, use it for a day and you won't go back to any other color settings.
[Samsung Galaxy Nexus] zetsumeikuro:
How long have you had your Nexus for now? Have you tried playing several videos as well as the white screen video? Mine had it pretty bad too until I started watching more videos on my phone regularly. Also did the white screen for about an hour or so and now it's pretty much gone.
[Samsung Galaxy Nexus] zetsumeikuro:
^This. After awhile you won't even notice the the extra bluish tinge.
[Samsung Galaxy Nexus] Formhault:
White requires the entire sub-pixel matrix to be activated - hence, wearing the screen more than other colors (which only require part of the matrix). Get it?

Applying common sense and standard thinking here results == DON'T DISPLAY FULL WHITE COLORS !

If you display a full white color for one hour, at maximum brightness, you increase the risk of the screen to loose maximum light intensity... hence, it will be dimmer. Worst case scenario is you get a white tint on everything, like a burn-in (LMFAO).
[Samsung Galaxy Nexus] zetsumeikuro:
Yet this works for people's plasma TV's and several people's Nexus'. If it works it works, if not nothing lost. These screens suck anyways.
[Samsung Galaxy Nexus] Formhault:
I just got my phone back from the so-called "service". They changed nothing. They "upgraded" the software (was 4.0.4 stock, now it's 4.0.2). They even forgot to re-lock the bootloader (so they probably used the same Galaxy Nexus ToolKit that's up here on XDA).

They didn't replace the screen, they didn't replace the earpiece. I now have to replace the screen protector, but oh well...

-----

Will try to let full white exposure for 1 hour or so, let's see if that fixes anything. If not, I hardly give a ****, I intend to wear the screen more so burn-ins become visible so the retards at the warranty service can notice them.
[Samsung Galaxy Nexus] zaneburton:
I just got off the phone with Executive Customer Relations, Samsung's third tier of support. The woman I spoke with said that the technicians didn't consider it a defect. Despite this, all the advanced replacements that I have sent back have had their LCDs replaced, suggesting that there is, in fact, a problem with the phone. Are you guys sure that phones exist without the purple? In stating that the techs didn't think that there was a problem with the screens, she suggested that all AMOLED+ screens are like this, which is absolutely absurd.
[Samsung Galaxy Nexus] LiViD:
After swapping my Optimus LTE with the GNex, the screen did bother me a bit. Going from an IPS LED screen to a Pentile screen is very noticeable, but I did get use to it after time. So far I have had no QC issues with my screen. Maybe I am just lucky?

A neighbour of mine has the Galaxy Nexus AND the Galaxy S2. He works at Vodafone and he replaced the Nexus three times so far - this one he has right now has no purple tine or image retention whatsoever (unlike the others he had before, which had ghosting from the very first day). He is going to ask for a refund, though, and given the fact that he's an employee, of course he'll get it, and us, normal citizens, won't...

He also said that whenever a customer comes for warranty purposes, the guys responsible for reparations are TOLD to do whatever they can just to avoid replacing any parts. Marketing :) can't blame them, though... these orders come straight from the top, so you can't really go down on the CEO's door and kill him... :rolleyes:

The brand-new LCD I got still had the same issues... They actually did repair it.
[Samsung Galaxy Nexus] Formhault:
The odds of that happening are somewhat low... but if you CAN make them send you another replacement if you're not satisfied with it, sure, I'd say profit...

First of all, it's not a LCD. It's an OLED panel - a completely different thing.

Second... They didn't repair it, they just replaced it. They can't repair such a display. But you got lucky... The "engineers" / "technicians" / "experts" / "specialists" that got their hands on MY phone figured "creaky earpiece? lines on the screen, not-so-bright gray, purple gray, not-so-white white? definetly software related, but let's peel the screen protector off, see if the colors are still the same... whoops, they're the same... go with the software downgrade, anyway, parts replacement is too hard for us to do".

I'll try to get that departament's number and see how much physics those... employees did in their faculty. My guess = none.
[Samsung Galaxy Nexus] osm0sis:
Took the plunge with Trinity Alpha 95 today - did the cwm flash - and I've gotta admit, the purples are gone, except a little bit of a bluish tinge to the edge of where they used to be at lower brightnesses! I do have a couple problems with Trinity so far though: purple/blue don't seem to be my problem now, it's more that the greys come off yellow/green at most brightness settings; and everything is SO dark now. Much darker than stock when using Automatic brightness especially.

Any ideas for these issues without buying - I don't want to buy until I've settled on a kernel. Also I was curious about content adaptive brightness... It sounds like Voodoo has put dev for that app on indefinite hiatus, and the thread seemed to indicate that the settings don't carry over on a reboot? Or can I set it once using the app, uninstall and forget? Thanks.
[Samsung Galaxy Nexus] zaneburton:
I just called it that because Samsung said that they "replaced LCD". I think that I'm just going to keep asking for advanced replacements until I get one that isn't purple.
