[Nokia Lumia 900] Phandemic:
I agree with koopiskeva. I just got the Cyan one while my sister and mom got the black one. Both of their screens were perfectly fine but mine had the distinct tint to it. While extremely subtle and hard to see at first the moment it goes from medium to high it is a jarring change. At first I wasn't too bothered by it, but upon further comparisons with my sister's phone the tint makes the screen significantly dimmer.

I went back and tried exchanging it. My first try the guy went through the phone hard resetting it and everything and he admitted he noticed that the keyboard was a different shade, but was unable to exchange it since I didn't have the box. Fair enough I came back later to a different store and funny enough this time I got the manager of the store. Predictably he gave me some grief over the phone and kept comparing the phone in the high brightness only, even though I had repeatedly said the problem isn't apparent except on the low/medium setting.

My advice is that you can get this exchanged and the best way to do it is to set the theme to the light theme so that you can really see the tint on the screen easier. Also don't take no for an answer! My experience has been that being nice doesn't help anyone. Even nice employees, who will roll over to jerk costumers who insult them, will more likely say no to nice people since it is much easier to say no to them. You don't have to be a jerk, just stand your ground.

Oh and fyi even some of the demonstration models they had had the issue letting them say that it might just be a standard thing with the phone and use that as an excuse to not replace your phone. I lucked out that one of their display models didn't(black one) and also that the manager's phone didn't either so I just told him hey just give me your phone and you take mine, since this screen doesn't bother you. Haha :D

I exchanged mine as well, it was driving crazy me changing colors on me as ambient lighting changed.

I put the phone on low setting and showed her the purple, she got a new one out, had me check everything and made the change.

i was very happy with how accommodating they were, I didn't have the box or even the charger with me but she just switched out the phone itself.

The new one is perfect!
[Nokia Lumia 900] idelgado782:
I got the black one and don't have any issues with the screen. Thank god. Purchased mines via best buy.

Sent from my Lumia 900 using Board Express
[Nokia Lumia 900] JMackey:
Rogers has a 15 day exchange policy so I'm one day over...

Anyone know where the Nokia repair centers are? I'd have to send mine there now...
[Nokia Lumia 900] gahbmwm5:
I just wanted to get this correct..so when I get contacted by the AT&T Corp store to exchange my present defective White Lumia, I will not run into any issues...lol...as I went into the 'brightness' settings and turned off 'Auto Adjust'...With High, and Medium settings going back to Messaging app...keyboard was bright and black...

So when setting 'brightness' to Low (of course Auto Adjust) was still turned off..going back into Messaging app--->keyboard was then purpleish..

Now....out-of-couriousity...I performed a hard reset on the device, and when going through the setup parameters....all keyboard functions were this purpleish color...

I would think that when setting the 'brightness' setting to low...with Auto Adjust turned off, that when going to the Messaging app, the keyboard would properly display this black/white lettering...just at a little lower contrast...but not the purpleish??

P.S. I put this also on another thread, prior to reviewing this one...thought it was relevent...apologies for the duplication...:o
[Nokia Lumia 900] kwill:
So long as brightness is at low level, you get the purplish tint. Auto adjust or not:)
[Nokia Lumia 900] gahbmwm5:
So this purplish tint at the low brightness setting (whether it is on auto adjust or not) is definitely a bug...

Those that are fortunate enough to have a device that does not show this purplish tint at all....@the low bright settings...with either auto adjust on or off?
[Nokia Lumia 900] godfa7h3r:
Asked Nokia Care about the issue via Twitter and they recommended a hardware swap. Seems like we are getting mixed results with this though. Some people are getting good units, others are still getting purple.

@godfa7h3r

@NokiaCareUS I also have purple hue on my white Lumia 900 when backlight is on low

Nokia Care US‏@NokiaCareUS

@godfa7h3r are looking into issue. Likely hardware related and suggest swap of device w/ retailer from where it was purchased.

White Lumia 900 Experiencing Screen Problems on Low Brightness?

http://winsource.com/2012/04/26/white-lumia-900-experiencing-screen-problems-on-low-brightness/
[Nokia Lumia 900] uiskibum:
My cyan lumia (does color really matter for hardware issues?) has the purple issue. I went to my AT&T store yesterday and checked out the three display units, and set them all to low and pulled up the dialer; the cyan and black units drew the gray fine while the white unit did not. I figured this would be an easy thing to explain to the sales person, boy was I wrong.

After showing them my phone compared to the display units the gal who was helping me didn't see what the problem was. And said that the white lumia was new so maybe that was how the new ones worked. sigh... finally i put it next to the cyan one since she couldn't get past the case color not being important. And told me I could exchange it for a restock fee. I calmly explained that this is not normal operation and that there is a hardware issue, and to an unofficial extent Nokia has acknowledge it on some support channels.

She asked me if "it affected pictures" I said, "well yes, the phone isn't drawing a shade(s) of gray properly so it will affect images". I finally had to pull up one of the supplied sample images and compare it to the display phone, and she finally realized that something was wrong. We did the whole show my manager song and dance. And they agreed to replace it without cost.

The kick was the comment "my manager is colorblind and he could see a difference right away."

Sigh...never going to deal with that sales lady again.
[Nokia Lumia 900] Zhariak:
I just picked up a Lumia 900 from Best Buy in Canada (for Rogers)...

I was rather surprised they had them in stock considering most companies aren't stocking any Windows Phone 7's.

I kept noticing immediately that my colors were off, kind of like being stuck in 256-bit before installing video card drivers on an older computer, hahaha... But it was intermittent...

Finally after googling "grey purple lumia 900" I came across a bunch of stuff... Did the back light intensity setting check, and it turns out I'm suffering from a purplish screen...

Seems like a lot of people are reporting this, yet none in Canada are reporting that it's NOT happening for them...

I've only got 14 days to return this sucker, has anyone confirmed yet if this is software or hardware related? If it's hardware, I want to get this sucker exchanged!
[Nokia Lumia 900] godfa7h3r:
Update:

Just got back from the ATT store. Did an exchange on my white Lumia 900 that had the purple screen issue.

Luckily, I have a friend who works at ATT who was accomodating. He took out two brand new white Lumia 900s so we could test them before doing an exchange. One had the purple screen, one did not. I swapped out and now things are great.

The short of it.. I don't think you'll see this issue fixed via firmware. Requires hardware swap.
[Nokia Lumia 900] gahbmwm5:
Yes indeed as my first Lumia 900-White purchased at a AT&T Corp store here in US...displayed this along with another issues..

http://winsource.com/2012/04/26/white-lumia-900-experiencing-screen-problems-on-low-brightness/

I exchanged today following tests at another AT&T Corp store....and after applying the latest firmware update...this purplish hue issue is gone..

However, other issues still remain, which have been acknowledged by Nokia and this is a good source of info..

Hate to be the bearer of bad news

Hate to be the one to tell you guys this, but I'm a long time Nokia N8 owner, this is a very very common problem with the AMOLED screens Nokia's been using from Samsung. Most common with the N8 and the E7 models.

This is not a software issue, the calibration of the screens are off. I've read numerous stories online with people making multiple exhanges with Nokia and they still get purple tinted screens, some have sent it into service centers to get the screens replaced and they still have the tint. This is all due to the bad batches of screens, and unfortunately there are a lot of them out there, but there are varying degrees of tint, some have a reddish/brownish tint and some have a very bright purple.

You will notice the blotches of purple when you watch movies, especially dark ones, the black background will start to pixelate when it's suppose to be dark or greyish.

The one I got exchanged the first time, still had a little purple in it but decided to keep it, so I didn't want to keep sending it back to get it "fixed" due to hearing all the horror stories of screen swaps.

The first thing I did when I got my lumia 800 was test for this issue, thank goodness my ebay unit did not have this screen problem.

do a google search "nokia n8 purple image test"

you'll find forums where it's discuess in detail, I would recommend you all download the two test images to see if you have an affected unit. The one with the white to black and the one with all the dark blocks to white.

Good luck to you all.
[Nokia Lumia 900] Zhariak:
I have the purple issue on my Black 900, however I just tested it with this image and it's not purple??? This is with the backlight set to medium.... I'm still not convinced...
[Nokia Lumia 900] kwill:
Apparently you haven't been reading the thread close enough:-) It's only with te backlight set to "low".
[Nokia Lumia 900] Zhariak:
Here's an update... I tweeted NokiaHelps (Nokia Care), and they told me to take it back to my retailer...

I took it back, they exchanged the phone for a new one. I just got home, plugged it in, and BAM there was the purple screen again... WTF!!!!

Am I just supposed to repeatedly return these over and over again until my 15 day return period is done?

Sounds like everyone that purchased these in Canada has this issue, I'd like to hear someone who didn't (I think the Canadian batch is different from the original AT&T batch).

I don't know if this makes a different, but on both boxes, it had "13 / 2012" on the box. I'm not sure if this is "Batch 13 of 2012 production year" or what, but I'm wondering if I should try returning again for one that is from a different production batch? Unfortunately noone is buying these here (they told me i was the first one since it's been released) at the store I went too. The store only had 2 to start with, I took the first, returned it, and now just got the second...

Ugh, frusterating...

EDIT: One more thing I noticed on my new unit. 1) The reds are more vibrant, more vibrant they should be. In a pic on the comp, someone looks like they are blushing which they are, on the phone their hole face looks red or sunburned. 2) The new phone is slightly scratched on the plastic where the glass meets the plastic on the bottom left corner. Looks like someone may have jabbed a seperator between the glass and plastic and damaged the plastic, might also be glue?!?!?
[Nokia Lumia 900] trueblog:
If every single phone has it then it must be a huge fail for Nokia or i am thinking this is software issue .. i just turned off auto and set to medium and moved on ... i still want Nokia to ack this a software issue and provide a fix soon ..
[Nokia Lumia 900] 22-40:
Week 13, most likely.
[Nokia Lumia 900] kwill:
Took mine back today. Two stores later and three different phones, we finally found one without the issue. Each rep could clearly see the difference when compared side by side. Not sure if that indicates hardware problem or not, but one things for sure have it, some don't.
[Nokia Lumia 900] Zhariak:
On the bottom sticker of the box with the barcodes, coudl you post (what I think is) the manufactoring date?

Example on mine is: "13 / 2012"
[Nokia Lumia 900] hhubble:
This is not a software issue

Sorry to hear about the issues, but this is definately not a software issue. This is why some have it and some don't.

In fact this is a very common issue even with Samsung AMOLED phones. I know of people that complain about a blue tint and a green tint, it just so happens for nokia phones they are usually a reddish or purple tint. Maybe the clearblack technology makes the miscalculated screens turn this color for Nokia.

I know they tried to hide the purple tint in the N8's with the Anna software update, by simply removing the color grey or dark from the start up and clock screen, but if you do the test or watch a movie, it's still there. In fact I know they have probably been trying to fix this for a while, since you only get it when the setting is low, with the N8's you could tell they're there no matter what brightness setting they were at.

If you can't get a phone without the purple tint within the 15 day return periord, you will have a 1 year warranty to get the screen replaced, I believe Nokia is aware of this issue and they will replace the screen for you, but the only problem is there are usually many patches with this issue, hence why you keep getting ones with the purple screen.

It's really weird too, I know they said the first or early batches of Nokia phones didn't have it (with the N8s) only the new ones seem to have it.

My lumia 800 is an early unlocked European model and it doesn't have this, but now with all these new batches of 800/900s coming out, there seem to be more reports of this.

I know it's frustrating, especially since a cell phone is such an important device for most of us, hope you all are able to get one with the right calibrated screens.
[Nokia Lumia 900] Zhariak:
So if this is a "known" issue, isn't it illegal to keep selling them? And as a consumer, are we supposed to just return these devices over and over and over until we get a new unit? I've read that some people have exchanged their devices over 5 times before giving up? I've already done it twice...
[Nokia Lumia 900] trueblog:
After hearing about some other users, i installed kindle app and gradually reduced the brightness in that app .. purple never came on that app . means its a software issue ..
[Nokia Lumia 900] kwill:
It doesn't have anything on it that looks like it would be a date range.
[Nokia Lumia 900] Zhariak:
What is the kindle app? And does it actually change the brightness of the backlight on the device itself?
[Nokia Lumia 900] trueblog:
http://www.youtube.com/watch?v=Ul_HxWbPG7k
[Nokia Lumia 900] prbassplayer:
Not illegal. Samsung kept selling Galaxy S with the sleep death issue. Most devices (I assume Nokia is no different) have 1 year manufacture warranty. You keep taking it to where you sold it and keep switching it. Worst case you need send it to Nokia for the "repair" or exchange. Not ideal but you should have a working device.
[Nokia Lumia 900] shoey5:
Doing some web searching, the purple tint seems to be a problem that plagues Nokia amoled screens. Finding other (non Lumia) devices complaining about purple tints on low brightness.

http://discussions.europe.nokia.com/t5/Eseries-and-Communicators/E7-LED-purple-tint/td-p/1369837

http://www.n8fanclub.com/2011/06/how-to-fix-purple-tint-issue-on-nokia.html

Depending on how wide-spread the issue is, I'm guessing Nokia is going to release a patch to fix (work-around) the issue by upping the value on low brightness intensity. Of course then people without the issue are going to be complaining that low brightness is too bright :)

This is just my own speculation as Nokia is yet to make an official statement on the issue.
[Nokia Lumia 900] Zhariak:
This is where I'm stuck... The volume of sales here in Canada are soo low that they barely keep any stocked at the stores (back when the Samsung Focus was released you couldn't even buy it in stores, you had to order it and get it shipped from the cell provider)... So for me to get a unit from a different batch is REALLY difficult since no matter where I go they all came from the same batch, exchanging would yield a new unit from the same batch... On top of that too, it sounds like they might not even refill inventory when it's depleted...

Again, I could be totally wrong about this... This is just what it sounds like is happening.

Technically I could order a unit from my cell provider directly, but this scares me considering I have NO idea what their return policy is, and I might get stuck having to send it in to get "repaired".
[Nokia Lumia 900] prbassplayer:
Remember that the warranty is with your provider its with Nokia. But since you bought it with your provider they need to "keep" said warranty, assuming they have the phone. If they don't then you need to contact Nokia. As to batch, that there I don't know.
[Nokia Lumia 900] Zhariak:
So here's a little update for you Canadians, eh?!?

I've been to most Best Buy's and Future Shops in Calgary... Apperently every store got 2 on launch. Most Best Buys haven't sold any, and all the ones I've come across are "13 / 2012" so I'm assuming part of the batch that I got 2 of that had the purple tint. I'm not sure if "13 / 2012" is a marker of the batch manufactored, I'm just assuming for now, if someone could confirm this that would be great.

All the Futureshops in Calgary also received 2 each, all the ones I've seen are "13 / 2012" however they are refusing to sell the phone's outright, saying you have to sign up on a 3 year contract to get the phone. They can't sell them outright (which is extremely odd, I've been told this at 3 Futureshops, they said the same applies to Best Buy, and pretty much infered I was lying when I told them Best Buy sold me the phone outright, the one I returned for a refund)...

I've got one more Best Buy to check out, even if it says "13 / 2012" I might just pick it up to see if it's affected by the issue.
[Nokia Lumia 900] shoey5:
Kind of hard to sell them when they don't even put a demo on display or offer it as a solution. Microsoft needs to go after them....maybe reminding them that if they weren't carrying xboxes that there are a lot of stores where people can buy Xbox units/games would be a start..... :)

In regards to them not selling it unless you get a contract, I've been told that too. They are trying to get contracts because that's where they make their money. Friend of mine asked the manager for his name so he knew who to direct the CRTC complaint too (against Rogers/manager of Futureshop)....he got one :) Not that Futureshop cares about CRTC but Rogers does in a big way!
[Nokia Lumia 900] sitizenx:
There are going to be a BOATLOAD of Lumia 900 refurbs on the market in a few months. This will be a free phone once again.

I ordered a black Lumia 900 direct from at&t and received it about 10 days ago. It has the purple issue. I'm going to exchange it. This sucks. I love the phone.

When you exchange the phone do they wipe it or do you have to do that at home first?
[Nokia Lumia 900] prbassplayer:
The old one gets sent to Nokia. They eventually wipe it BUT if you have any important info on your phone I would wipe it before hand just in case.
[Nokia Lumia 900] Zhariak:
I was absolutely shocked they refused to sell the device. Is Microsoft aware of what's happening in Canada? Are they aware that the reason why they aren't achieving a decent market share is because of the various parties that are involved in manufacturing/selling process? And at the same time, what would complaining to the CRTC do?

I've been a die-hard Windows Mobile guy, and a die hard WP7 guy all my life, but all my devices have had defects (Samsung Focus, and Nokia Lumia) and as far as the Focus goes, if I wanted to get it fixed, I'd get a POS refurb, and as far as the Nokia goes, I have 14 days to exchange or refund, or I'm stuck with it.

I love the OS, but it's just soooo damn hard to get a decent device (especially since there's only a few available with my provider which is the main one in Canada), and latest example, refusal to even sell the device...

Microsoft is trying so hard to sell these, but when a customer goes to buy one, he's refused, epic fail. Is Microsoft even aware of this???

Such a beautiful OS, but the whole situation is soo soo sad.

Here an update I just threw up on my blog (don't worry I'm not advertising the URL). Found this interesting:

"Also, here’s something interesting… Turn your phone off, or put it to sleep: Go somewhere close to a light, and use your phone’s screen to reflect the light (as if you were looking through a mirror at a light. Notice how there is a purple haze around the light in the reflection on the phone. I’m almost positive this is hardware and it has something to do with a internal coating in the screen."

It almost looks like theres a internal film, or something is mis-colored. When I reflect I white light using my phone's screen (when the phone is completely off), I notice purple haze, hue, or you could even call it a halo around the light. Fact is, it's purple, and the phones off.
[Nokia Lumia 900] jbird951:
I just got back from the AT&T store up the street, the female who helped me acknowledged the purple thing and said, and this is pretty much a quote

"this isn't a problem, we have internal emails from AT&T about this. It's a "feature" that only the white phone has."

I didn't know how to respond lol. Before I went on a trying to explain WTF sense does that make I'd like to know how exactly does this effect my screen? Her + her manager, and if they're not lying apparently the big wigs at AT&T are viewing this as a complete non issue.
[Nokia Lumia 900] Zhariak:
It's just like how my neighbors car engine squeals and hurts your ears when they turn it on. It's a feature right? *facepalm*

You should tell them the Black 900's in Canada also have this "feature".
[Nokia Lumia 900] jbird951:
Well, in her defense *I suppose* she doesn't think the grays are purple, she thinks the white model's suppose to have a purple'ish keyboard to further distinguish it from the black and cyan models. I just hope either AT&T or Nokia step up and do something about this. I'm guessing this problem would make anything gray look purple/bad? Honestly before this thread I was blissfully ignorant. But now my brain is forcing me to see the flaw here lol.
