I don't think anyone here can speak to the true nature of the purple tint, but it just seems like poor quality control or calibration on the screen itself. I can't see how it would harm the phone.

Personally I got an exchange from Samsung and it's just as bad as the first, though the first one also had a red tint to the right edge which was very noticeable on the keyboard. Been on hold with Google Play for 37 minutes as I type this waiting for someone to answer. I don't want to go through the Samsung replacement game again, I'm trying to find out if they can exchange it themselves or just take a return (without restocking fees :eek:) and I'll order another from the new batch.

Not sure what your options are if you're really in Cairo. If it doesn't bother you, just keep it.
[Samsung Galaxy Nexus] millicoelho:
FYI, Google would not do the exchange but they would take it back with out restocking fee if it is defective.However you would lose the shipping cost. Anyways let's know how it goes and also what they have to say about returning a replacement phone.
[Samsung Galaxy Nexus] chrisjs81:
They said they'll take it back and that they'll put a note in there to waive the restocking fee but they can't guarantee that. It's up to Samsung who examines the returns to waive it.

They're having me send back both phones in the same box. I guess it all goes back to Samsung in the end.

Interestingly, the guy from the Play Store told me that Samsung is "no longer" considering the purple tint to be a defect unless it's really bad. In the past they always considered them defective. I guess I could deal with it if I didn't also have image persistence problems and red tint on the right edge of the first phone.

I'm not sure what I'm going to do from here. I planned on ordering another one but I'm also worried I'll just get another bum one, plus I'm concerned with the "might waive the restocking fee" return.
[Samsung Galaxy Nexus] millicoelho:
As long as they mark it defective you should get the money back(it is not feasible to wait for samsung's confirmation to refund your money). But do you know for sure the new order would not have any defects? If you plan to buy this phone again, it is better to keep trying the exchange. At least you would not lose your shipping cost.
[Samsung Galaxy Nexus] chrisjs81:
I don't but it took Samsung a week to send me the first replacement. If I called for another one now by the time I actually received it I'd be outside the 14 day window so no more exchanges after that, only repairs.
[Samsung Galaxy Nexus] enik_fox:
Been tempted to exchange mine for the grainy screen but my cell radios are rock stable and I literally have no other issues that affect the use of the phone so I don't think that its worth the risk to exchange it. Only another 6 months till I get another upgrade anyways so I think I can live with it.

You guys can use the Trickster Mod app to tune colours for compatible kernels. The app is free in the App section.

Sent from my GNex running Jelly Bean 4.1.1
[Samsung Galaxy Nexus] cmstlist:
Ok, just flashed Trinity. Holy smokes, what a difference! Now I really see it.

At super-lowered brightness (via RootDim) the purple is still a bit visible when looking at photos. At normal-low brightness, the lowest greys on that black level web site actually look a little bit olive-green and then the next row is pretty much dead on grey.

Don't have a controller app installed yet. Any thoughts on whether a small final tweak would make my greys truly grey?
[Samsung Galaxy Nexus] defconoi:
for whatever reason trinity seems to be giving me better screen color, but im sure I could do the same with franco, anyways, my gamma settings are untouched, I found that modifying the color to these values makes the purple tint go away for me:

Red:135

Green:135

Blue:190

Trinity Contrast -15 to -25

btw, could this just be a contrast issue?
[Samsung Galaxy Nexus] Rinthe:
mine looks very black
[Samsung Galaxy Nexus] cmstlist:
Well I'm happy with the colour enhancements on Trinity but the performance is lousy. My phone has become very laggy in terms of UI response. Such as pressing back, getting no response, pressing it again and then it registers a double press with two vibrations. I expect that of my Nexus One but not a GN. I have never experienced that until after flashing Trinity.
[Samsung Galaxy Nexus] chrisjs81:
I changed my mind and ended up going through Samsung for another replacement.

This is now phone #3 and I think I'm satisfied. It still has a bit of a purple tint but it's better than the first two phones. It also completely lacks the red/green color shift affecting the first two. Phone #1 had a noticeable red gradient coming off the right edge. Phone #2 had a red circle in the upper left.

Aside from the purple still being present, if I had to pick apart this screen, I can tell that there's inconsistency in the gray brightness from the top to the bottom. The top 1/8 of the screen is a little brighter when looking at a dark gray, the bottom 1/4 starts to trail off a bit darker.

I've come to the conclusion that few to none of these screens are perfect, either other people are getting occasionally lucky OR I'm just being too damn picky. It's time I stop worrying myself about this and actually enjoy the phone.
[Samsung Galaxy Nexus] Upstreammiami:
I've trinity colors there so much better
[Samsung Galaxy Nexus] MS.:
Change CPU governor to "interactive". By default Trinity kernel is set for best battery life. When everything is properly set this kernel is amazing. Or you can flash franco.Kernel, it's very fast out of box and supports color control.
[Samsung Galaxy Nexus] LNJ:
Anyone here do an advance replacement from Samsung Canada?

I would like to do one directly with Samsung rather than Rogers.

I have 2 units and one has a brighter screen with almost no grain and no tint issues. The other is well, the total opposite.
[Samsung Galaxy Nexus] Vertig0:
How can you get a replacement from Samsung and who qualify?
[Samsung Galaxy Nexus] defconoi:
samsungs replacement process

hey guys, I think im gonna go for replacement #2, it still is purple, but much less, also there is an authorization still on my card, I ordered the phone on July 3rd and got my replacement a week ago, will I still qualify for advanced replacement? How can I get them to ship me out a new phone since its past the 14 days I originally bought it? Or is the advanced replacement warranty renewed after each replacement?

Thanks

Kyle

My problem went away with franco kernel and trinity contrast tweaks i put a s2 on side and tweaked it to same colors with non purple

[Samsung Galaxy Nexus] rllong1:
My screen is grainy when on low or auto brightness. But on 50 percent or higher. Everything looks normal. I have no banding or purple tint issues. Actually trinity kernel made the colors look off so I think my phone is fine. But is there a way to fix auto brightness?
[Samsung Galaxy Nexus] joyern:
same problem on my galay note

I have the same problem on my galaxy note and it is more than anything i have seen cruising the forums and youtube.

but it only happened after updating to ICS. On GB rom it is completly normal. i have tried many different ics releases now including the nordic offisial trough kies. same problem. so I am stuck on GB rom for now where it works perfect.

anyone has any idea?
[Samsung Galaxy Nexus] Sienna Hanon:
I'm in the same boat. Ordered on July 3 as well, want to go for replacement #2. Spent an hour on the phone today with Samsung. Went through support tier 1, tier 2 and executive tier. Tier 2 tried to pawn me on the "galaxy nexus" division (who diverted me to corporate in the first place...) Executive tier basically said "Nope - you are beyond your 14 day window, no advance replacement for you! Return the worst phone under the advanced exchange program, and send in the other phone for repair."

So, good luck. This has soured me from ever buying a Samsung phone again.
[Samsung Galaxy Nexus] millicoelho:
Got the 3rd replacement today. This is the best - no purple tinting. Grey looks really grey.

But in white(or any light color background) half the screen looks darker than the other half. Time has come to pick what I can live with as I can't get any more replacement ( nor I want to try even if they offer). I lost my hope of getting better replacement. The original seems to be better with even rendering of white/light colors.

[Samsung Galaxy Nexus] gotokyo:
Pretty bummed, I'm getting my phone replaced due to the charging issues and the replacement phone they sent me has this purple tint problem.

I ordered my phone on the 11th (preorder at the time), it shipped on the 13th, and delivered on the 16th. I'm not sure exactly when the 14 day return policy starts. Anyways I got my replacement phone yesterday (30th) so it's been exactly 14 days since I've personally had the phone.

I called customer support yesterday (30th) saying it's got the purple issue and I want a replacement. The guy told me the wait would be 45 mins or so before I can talk to the person I needed to. So instead of waiting he sets up a call back which will be sometime today (31st). That exceeds the 14 days since I've personally owned the phone. So I'm really nervous as if they will give me another replacement or not since its right on the edge of the warranty.

Since both my original phone and replacement phone shipped on a Friday, those extra weekend days really ate up a lot of warranty days, and now this call back is adding an extra day :(

So now if it doesn't get replaced I'm stuck with either a phone with a perfect screen but known to have charging issues, or a phone with a purple tint screen and unknown if it will have charging issues...

Uhh sorry it's kind of a long post it's just frustrating. If I'm spending $380 on a new phone I want it to work and not have to settle with one problem or another.

CN: replaced phone has purple tint issue, right at the edge 14 day warranty, not sure if eligible for another replacement. frustrated :mad:
[Samsung Galaxy Nexus] arzbhatia:
If they say you've crossed the limit, blast off at them and say its you who've eaten up my warranty days. I haven't used it even for a full day!!
[Samsung Galaxy Nexus] soulja786:
My phones screen also looks a little grainy on light backgrounds... is this because I've just come from using a retina screen or is it a real issue? :/
[Samsung Galaxy Nexus] millicoelho:
It is a common issues(or non-issue) with nexus to have grainy screen in the lowest brightness settings. But with auto and/or about 10-15% brightness, it should not be visible which is the setting you would be using the most.

---------- Post added at 10:47 AM ---------- Previous post was at 10:40 AM ----------

It is from the date you got the phone delivered. Since you called them yesterday which was the 14th day, you should get the replacement. But keep in mind, the replacement is not going to be perfect most of the time. I would recommend keeping all the phones till you get the replacement so that you can pick the better(what you can live with) among them. If the original looks good, you can send it for repair to fix the power issue past 14 days.
[Samsung Galaxy Nexus] theredspecial:
Grays/White is looking very grainy, along with horizontal lines on auto brightness. This is my third CLNR, the first one without cosmetic damage. I guess I'll be going for #4, but I have no idea of what should be "acceptable". Does anyone not have any graininess?
[Samsung Galaxy Nexus] veyka:
My phones screen goes purple at lowest brightness, and very very slightly at other low brightness levels, my mothers phone is very similar, my phone was brought within the past week, mothers only a few weeks before that.

I have been trying trinity and franco and other custom kernels, the screen does seem to look a bit better with slightly tweaked trinity values.

But I suppose I need to compare it side to side with another phone.

I actually find the more I read about these "issues" the more I see them :p
[Samsung Galaxy Nexus] strumcat:
I think everyone has at least a little of the graininess and visible black "blobs" at almost black settings. However, some phones don't have the purple tint or horizontal lines. I guess I was lucky, because this screen has no issues I can't live with.
[Samsung Galaxy Nexus] strumcat:
Hey, just had an idea. I've noticed that the pattern of the graininess varies with the brightness setting. You might be able to find a brightness setting where it's not noticeable.
[Samsung Galaxy Nexus] gotokyo:
Whew..

Just got off the phone with a samsung rep and their sending out another replacement. The rep told me that the 14 day warranty resets for every replacement phone.

What a relief. I was worried I was going to be stuck choosing which issue I had to settle with.
[Samsung Galaxy Nexus] millicoelho:
Good luck with your replacement. Hope you get a better one:) (probably one of the phones which I returned...just kidding!!)
[Samsung Galaxy Nexus] veyka:
So today I finally stopped sticking my head in the sand and yelling LALALA to myself and noticed that along with the purple I have some weird vertical lines (They seem to be part of the screen, not the glass or scratches) and the purple is pretty damn bad.

Good News it that as I got the phone with amazon uk they are shipping a replacement by next day, and I have 30 days from today to return the old one, and they pick it up from your door, pretty chuffed at the service, not so much with the problem :(
[Samsung Galaxy Nexus] rafa3L:
It took 3 replacements (so forth phone including the original) for me to get a purple-free Galaxy Nexus. On my 3rd I was concerned about going past the 14 day window so I actually returned the phone and re-ordered. I wasn't aware that Samsung reset the 14 day window after every replacement.
[Samsung Galaxy Nexus] matthewr87:
I can't believe GNex phones being produced now still have the problem. I ended up returning SEVEN units before finally settling on one that only had purple tint, graininess and banding at very low brightness. I just couldn't handle any more returns and so I cut my losses.
[Samsung Galaxy Nexus] AmericanCon:
Have you ever thought that maybe that's just how the screen is? People take advantage of warranties as evidence of this thread. I have a hard time believing that seven devices had a "defect" where it was more likely too much expectations or pickyness from the user.

It can't be luck that I have not seen these issues but on very low brightness and this is my first and only gnex. Not to mention I bought it used.

And from what I understand, it's because the pixels need full brightness to be 100% white. It's just the nature of the beast.
[Samsung Galaxy Nexus] :
on low brightness mode oled's suffer from color wandering and flicker. This is a known problem of the design of the oled itself. They also don't last long, this is why you dont see oled tvs yet.
[Samsung Galaxy Nexus] matthewr87:
I know it sounds crazy, but I actually wasn't picky at ALL. If I wanted to be picky I would not have kept my current phone either.

Nexus #1: Horrible GREEN tint to screen at all brightness levels. Clearly defective

Nexus #2: Purple tint and graininess on brightness settings at and below 50%. My brightness is usually 50% and below so this was unacceptable

Nexus #3: Purple tint at brightness at and below 50% and would get REALLY hot whilst talking on the phone. So much so that it made my hand and ear/face uncomfortable

Nexus #4: Probably the nicest screen I've seen on a GNex, but it came with a giant 2 inch scratch down the middle right out of the box

Nexus #5: Extreme case of vertical banding at all brightness levels and a line of dead pixels

Nexus #6: Speaker blew out within a few minutes of use.

Nexus #7: Screen was horriblly washed out and grainy at all brightness levels.

I would have quit after the second phone but I used up my upgrade and had to sign a new contract so I was stuck.
[Samsung Galaxy Nexus] AmericanCon:
Damn... Im sorry for that lol.
[Samsung Galaxy Nexus] millicoelho:
Wondering if anyone got a phone with no tinting/grainy/banding/lines when the brightness is at the lowest settings. That would clear up the air who is trying to find a perfect phone.
[Samsung Galaxy Nexus] AmericanCon:
This is what I was getting at. I'm pretty sure everyone has these issues on low ler settings.
[Samsung Galaxy Nexus] millicoelho:
I have seen postings that claim 'cause of oled/pentile technology, it is known to have these issues at low brightness. So trying to see if there is a practical proof to it. But probably we would never know since people got the perfect one(if there is such thing?), would not be watching this thread:)
[Samsung Galaxy Nexus] gpzbc:
I'm sure there is not a perfect screen that does not have this issue, but I can tell you after exchanging my GNex 7 times, there are some that are better than others. I had a few that actually had lines that resembled a plaid pattern. My current GNex has a pretty good screen, although still purple tint at lowest brightness settings. The Display Tester app in the Play Store was quite helpful in determining how good the colors are.
[Samsung Galaxy Nexus] :
It really isnt about a certain amount of color change or amount of wandering. Basically put, at low forward bias voltage levels the led isn't as stable, so that is why some flicker some change color some do both. The easy solution is to not allow the user to push the brightness down below that threshold but then you would have a greater amount of users upset that their screen wont get dark enough. So in the end the manufacturer has to choose the lesser of two evils. So that is why at the end of the day YMMV when using it in low brightness mode.

hate to use wiki but is actually quite accurate in this case

http://en.wikipedia.org/wiki/OLED#Disadvantages
[Samsung Galaxy Nexus] veyka:
Thanks for the hint on that app.

The main reason I am swapping mine is the weird marks on one side of my screen (Will try to get a pic sometime).
[Samsung Galaxy Nexus] strumcat:
The big problem with these phones is that the gamma is set so low by default. This makes the middle brightness levels too dark, accentuating the purple tint problem. If you increase brightness to bring the middles up to normal, the whites are too bright. The fix I'm using is to install Trinity kernel, then use Trinity Kernel Toolkit to bring gamma up to a normal level. You have to put all three gamma sliders on maximum (20) to get a normal gamma on a reference chart. Then set contrast to about -10 and all three color sliders at about 150. Each phone has a different tint, so adjust each color slider about 150 +/- 10 to get rid of any tint. At that point you can set brightness to auto and it's bright enough for normal use.
[Samsung Galaxy Nexus] strumcat:
+1

Yeh, the Display Tester app is pretty good, the best I've seen on the play store.
[Samsung Galaxy Nexus] gotokyo:
Not true.

My original phone had a perfect screen, no purple tint or graininess what so ever. (original had to be replaced due to charging issues)

I was able to compare the original and the replacement side-by-side and even at the lowest brightness setting there was no purple tint to the original while as the replacement phone had graininess at very low brightness and a purple tint throughout all the brightness levels. (darkest being the most visibly noticable)

So to say that that's just how the phone is and how its supposed to look is simply not true.
[Samsung Galaxy Nexus] rafa3L:
The three phones that I returned were not only purple at their lowest setting but also purple with auto brightness. They were all different levels of purple. The grays on the settings screen, notification pane, and other apps with gray such as news and weather and calc and more all had noticeable purple. The 4th GNex I have now and also my wife's GNex does not have these noticeable purples with auto brightness. Sure if I put it on the lowest brightness and decide to be picky then I think I could say I see some level of purple, but that's not the reason I used the 14 day advanced RMA period to return 3 phones. The purple I was seeing was unacceptable.

[Samsung Galaxy Nexus] imported0:
I just bought this phone and of course I also have this problem.. But my brother on the other hand has the same phone, but there is a big difference, my gray on lower brightness is as purple as it gets,notification center is purple,keyboard is purple, everything that has gray in it is purple.. On his phone, on lowest brightness,you can barely see the purple,it is there, but not as much as on my phone.

So my question is, how much purple is "normal" and when is it too much?

Also, I have warranty, but i rooted and installed the 4.1.1 ota custom rom (update wasn't available for me) should I and can I still go to get it fixed or replaced,and will warranty cover it?

Thank you everyone, btw. Im just back on XDA after being on iPhone for 8. months.. Glad to be back.

Hope I get a response soon. Cheers

EDIT: I'm getting the purple also on auto-brightness,is that normal?

I just need someone to tell me that my phone is normal xD
[Samsung Galaxy Nexus] scoobdude:
So my wife has the perfect screen while mine was quite purple. Running cm10 I was actually able to get mine better looking than hers as per her and i (opinion). But 97% of purple is gone and with no black crush.

Here are my settings on stock cm10 with stock kernal, hope they help.
[Samsung Galaxy Nexus] gpzbc:
Thanks for the screenshots of your CM10 settings. I haven't played with those, but I may since my latest replacement phone still has slight purple.
[Samsung Galaxy Nexus] scoobdude:
Not a problem. Mine was I would say about 80% extreme purple from pics I have seen. And while I am much happier with those settings they are a tad green which the gamma setting does not work on. But its so much nicer. Will see if I can get some before and aft pics with my wife's phone in their as well for comparison. Give me a fee days for that though.
[Samsung Galaxy Nexus] fayosi:
The screen is soo weird but the blacks in pictures are amazing
[Samsung Galaxy Nexus] scoobdude:
Fayosi which ever settings you are trying remember every screen is different. So additional tweaks will need to be made. And in addition to that give your self some time to test drive it. Apply same rules as when adjusting TV basically. And also try different brightness levels. Pick and choose your compromises.
[Samsung Galaxy Nexus] millicoelho:
With one of my replacements(out of three) I had a perfect grey but with another issue(white with tint). So I know there are phones with no purple tint at all but it may have other issues like grainy screen, tint on white screen etc. You can try warranty repair. If you get purple with auto brightness I would think it is bad. Is it very obvious or do you notice it when you do side-by-side with the other phone?
[Samsung Galaxy Nexus] imported0:
When I use it at night,its like Im using some purple theme for cyanogen,everything is purple,including keyboard and that notification thingy. On auto brightness its quite noticable,not as purple as on lowest brightness,but its still there,I can see it without comparison with my brothers phone..

Also,I dont know should i replace it,it might just get worse...
[Samsung Galaxy Nexus] imported0:
Wow,nice, does that actually work? Is that the CM10 Nightly?
[Samsung Galaxy Nexus] scoobdude:
Screenshot was from the unofficial one. Am now on latest with same results.

You are now using official one or?
[Samsung Galaxy Nexus] scoobdude:
yes. on the 8/21 official build now.
[Samsung Galaxy Nexus] Shadowfox993:
The liquid rom for maguro made the screen color perfect, the blacks were pure black, and the colors looked normal. Now I'm running aokp jellybean build one and now the bs color is back. Tell me why? How do I fix this
[Samsung Galaxy Nexus] thegtfusion:
Try to flash the trinity kernel. The colors are amazing with it.
