No problem - glad you found it helpful! I'm going to try the same test myself, once I get home, against my calibrated PC monitor.
[Nexus One General] Paul22000:
As I said, BGR is nothing but a bunch of Apple fanboy garbage spewing out unsubstantiated Android hate for no reason.
[Nexus One General] akgrown:
Well, there's still the possibility that some units have a skewed color temp/saturation. I'm hoping my results will align with strongergodzilla's, tho.

Also, the tint is definitely most noticeable at the lowest brightness setting, so it might take a little tweaking of monitor brightness to compare apples to apples. However, if the colors match up at "normal" brightness levels, that's good enough for me.
[Nexus One General] liorra3:
here you go (from some angles), on the bottom is the atnt:
[Nexus One General] elite_is3:
Actually in the past with the numerous iphones i had, there were many times when SERIAL numbers were passed around about which iphone series had a better screen and so on. Which turned out to be fairly true, it was merely a hardware change or different screen manufacturer source who knows. But i for some reason DOUBT its a quality control problem that me though
[Nexus One General] melterx12:
I definitly see more vivid and deeper colors on the top nexus one than the bottom, also I compared the pictures with the kodak test on my monitor and while neither phones make the colors look exaclty as they are on my monitor, the top one def comes closer, especially in the greens.

well the tmobile nexus ones are confirmed to use a SAMSUNG AMOLED display, and samsung makes very high quality displays. I wonder if a different manufacturer makes displays for the AT&T Nexus One, or maybe they just changed the color settings on the display, or maybe its jsut a different revision of the same display?
[Nexus One General] esincho:
U are soo right. Engadget 2!!
[Nexus One General] NexusDro:
Someone needs to open up their AT&T Nexus and see if it uses the same samsung display.
[Nexus One General] rotohammer:
You first :)
[Nexus One General] h2opoloplyr_11:
Thats weird i did read about this report after i had ordered my att version. Luckily i still have the tmo version for comparisson.

This is weird, because from the looks of my n1's the tmo version is the one with the purple-ish hue to it.... i tried to get the two phones brightness level the same. and this is the result.

Att (left) tmo (right)
[Nexus One General] bradsh1:
One on the bottom is clearly superior. I don't get what people are complaining about. If anything the colors on the T-mo N1 have ALWAYS been jacked, from day one people have complained.
[Nexus One General] faraz1992:
Most of the sites.... they can do anything when it comes to posting crap....
[Nexus One General] melterx12:
are you blind? The colors on the top are clearly more vivid, deeper, and closer to the intended image.
[Nexus One General] bradsh1:
On the contrary, the colors on top are inappropriately reddish. Take for example the gray frames in the image which are gray on the bottom and often pink on top.

Either way, it's probably a matter of taste. I would similarly ALWAYS take an anti-glare LCD screen on a laptop over the glossy garbage found in nearly all of them now, even though glossy "pops" and is "more vivid".

I would rather have correct colors than blown out over contrasted garbage. Faces always look ridiculously red in the pictures I take on my Nexus One (T-mo) and then if I move them to my PC they look fine. So for me at least, the Tmo N1 definitely has some reddish tint.
[Nexus One General] distortedloop:
I always thought the Nexus One (TMo version) pushes red too much. It used to annoy me on some video podcasts with the flesh-tones of the talking heads. I guess I got used to it; I hadn't thought about it until reading this thread.

As someone else mentioned, iPhones made a lot of noise a few years ago when the 3G hit the market and people noticed it was much "cooler" and bluer than the original model. It was very noticeable to me when my original phone was side-by-side with the new 3G.

Apple changed the screens; it's reasonable to expect that HTC is doing so, too, since over-saturated reds are a common complaint I've read of the N1.

I'm more interested in if the AT&T phones have that multi-touch crossover issue like the TMo ones.
[Nexus One General] thevoiceless:
That's exactly what I was about to ask; This was the first thing I thought of when I started reading about the differences in the screens.
[Nexus One General] coolbho3000:
It still has the "issue."

It's still the same Samsung panel. There are probably variations between batches of the panel. There's considerably less of the "red shift" on low brightness on my AT&T N1, about the same on higher brightnesses.
[Nexus One General] distortedloop:
Well, we could only hope. The N1 is fantastic, but it's definitely got some issues with the display, in many different ways.

The lack of red shift may be just the proverbial straw I need to push me to get the AT&T version of the phone and just move my iPhone SIM to it. Then I'll sell this T-Mobile one and get the heck off that crappy service. EDGE only in my house, no service in most of my neighborhood, 20-60% failure rate on sending MMS messages. I like the customer service, and the rates on T-Mobile, but they're just not a high quality/reliable carrier here in my part of Los Angeles.

Maybe I should just wait for Verizon phone to come out and check the rate plans vs AT&T.
[Nexus One General] Ok_Kaleidoscope5109:
N1 definitely feels like purplish/reddish compared to my Milestone. Pics coming soon. I'm at work. People might look at me funny as I have my dSLR at work, and I gotta hook it up to my laptop? LOL
[Nexus One General] pongalong:
I had an opportunity to look at several at&t N1's. Pulled out my own t-mobile one and didn't notice any difference really. As someone mentioned there may have been a slight hue change at lower brightness levels. If there were any differences in the ones I looked at it was so minor that I just wrote it off.
[Nexus One General] j.bruha:
I have two T-Mobile N1's in the house and an AT&T N1 right now. I see the difference. They both look great. Move along.
[Nexus One General] jollins:
Agreed. I've had both.

Yes the screens look different, but the tweaked color reproduction doesn't neccesarily mean its better it worse. I'm neutral when it comes to which I prefer.
[Nexus One General] fescen9:
I just got my AT&T version today (after just getting rid of my T-Mobile version) and it's has a definite bluish hue and a noticeable blue "cloud" at the bottom. I've read of others having this problem as well. The attached pic is slightly more pronounced but this is very close to what it looks like in person. I contacted HTC today and they said there's a known issue that they're looking into and had no further advice than that.
[Nexus One General] clownfart:
Got my ATT N1 yesterday and one of the first things I noticed was the purple/red hue. I never had a Tmobile version to compare it too. It seems as though it appears as the brightness level goes down. At the brightest level whites are white and not purple/red as they are at medium brightness.

Is this a cause for a return?
[Nexus One General] Schwacker:
I've been thinking about buying a n1 this week but man, I'm not going to drop $500 on a phone that has this problem.
[Nexus One General] NexusDro:
My ATT N1 also looks bluish in low brightness compared to my old one. But I can't say it looks worse than my tmobile version.
[Nexus One General] Ok_Kaleidoscope5109:
I have to say this is true. I set my Milestone and N1 side by side on Auto. Somehow the Milestone boosts brightness from the default. Looks quite good actually. The N1 drops brightness from my default which is like 15-20% from bottom, and drop is dimmer and I see the purplish tint. It seems like a red shift in the screen. However, I don't like running at that, so I usually keep it on manual between 15-20% where it blows out the Droid at similar brightness.

I like the saturatedness of the N1. Maybe it's not so bad when you boost the brightness, but I have yet to go to Lagom's LCD test images to verify. Seems like a red shift to me in the color calibration.

To those saying this is a killer, this isn't. This is small. Your bigger problems are the low earpiece volume if you're anywhere other than a silent room... and the terrible RF.

This. Precisely why my Macbook Pro is a Matte display and not that glossy crap. I laugh at those who want glossy. You get deeper RGBs but that's far from accurate. For those of us that calibrate monitors, you wouldn't want glossy anyway. Have fun looking at a mirror. At least that's what it seems when I walk into an Apple store. Mirror-like glossy :D Why would I want to see myself in my own laptop?
[Nexus One General] NexusDro:
I found the earpiece volume acceptable if you position the earpiece properly next to your ear. I found that you have to lower the phone a bit next to your ear to get the perfect volume.
[Nexus One General] SiNJiN76:
Next to my wife's phone (has excellent whites) mine is not as bright and has a bluish tint (never noticed 'til I compared to wife's)....That's why I don't use mine next to hers.

It happened to my wife's BB...it was on the RED side while mine was perfect.
[Nexus One General] clownfart:
Any way to increase earpiece volume? Do the modded ROMS do it?
[Nexus One General] NexusDro:
At max brightness, the ATT version is not as bright as the Tmobile one...
[Nexus One General] parvo99:
red hue

here's a pic I took showing a youtube clip on my laptop screen, iphone (left), and nexus one (right). Definitely a strong reddish hue.

[Nexus One General] GldRush98:
I was going to chalk this up to people being nutso... but...

Damn, there is a substantial difference there. I can't say I can see any color tinting on mine... but I don't have a different aged Nexus One to compare to.
[Nexus One General] dr1337:
Yes, I actually have 2 T-Mobile Nexus One and one actually has the described pink/red shift calibration error.

I wonder if this can be remedied by a firmware fix?
[Nexus One General] Eclair~:
When I first got my N1 (it being T-Mobile doesn't matter, I believe its the time of which the device was created, there all being manufactured by HTC) it also had the Orange tint. Over time, it started to to way - whites once became whites again. Everything soon became perfect. Don't know if this contributes to the discussion, but im starting to believe it is only temporary.
[Nexus One General] x986123:
My brand new AT&T 3G just came in the mail, and I can say that the screen is better quality then the T-mo version. No more pink/purple tint, looks a little more blueish, but VERY unnoticeable.
[Nexus One General] dr1337:
So I did a replacement swap for my faulty Nexus One and the replacement unit that was sent had the low brightness pink screen issue too.

I spoke to the Google Rep and she said that this is a known issue and that they can't seem to find a pattern in its occurrence. They think it might be random batches that have faulty screens.
[Nexus One General] Ok_Kaleidoscope5109:
PURPLE!!!!
[Nexus One General] drdingo21:
Just got my new ATT version and there is a definte blue tint to the phone. However slight it is, its there.

Its annoying because I came from an iPhone 3gs and I can plainly see it on low brighness.

I'm debating about requesting another one...
[Nexus One General] NexusDro:
The blue tint gives the screen a cooler colour temperature. Is it necessarily a bad thing or just a personal preference? I'm actually neutral between the warm and cool colour temperatures.
[Nexus One General] Eclair~:
Honestly I believe its people being overly picky, and I'm quite surprised HTC is replacing their phones over something that eventually goes away (at least, for me). The problem is something that people can easily get over, but it seems that because it is not apparent on all devices - people find the need to get their phones replaced.

I had the same orange tint on my brand new phone also, but instead if insisting on getting it replaced, I waited. Luckily for me, it went away. I guess for those whose it doesn't go away, I guess it would be something irritating enough to have looked at.
[Nexus One General] fescen9:
Replaced My Phone - Much Better!

All,

I posted a screenshot of my "blue cloud" problem in this thread a couple pages back. I replaced my phone and let me tell you, the difference is very noticeable. Since I had the T-Mobile version prior to my AT&T version I know that the screen looked great but when I got my first AT&T version I knew something was off. A noticeable blue cloud toward the bottom, off looking color, etc... The replacement that just arrived is more crisp, brighter, no blue cloud; It's beautiful like it should be. Now comparing the T-Mobile to the AT&T version (when the screen is working properly) then yes, the color temperature is a little more on the cool/blue side but the problem I had was something different. If yours looks like my screenshot then replace it, you're missing out.
[Nexus One General] drdingo21:
I called google support about this issue. They just asked if I had tried to hard reset the phone and then sent me over to HTC.

The guy at HTC said it was a known issues with ATT phones and the issue has been corrected. He said he could only send me a refurbished phone....

That sounds odd to me as I just received my phone on Tuesday (4/5).

It really pissess me off that I just paid the $530 for the phone that is defective and I need to send it back just to get a used refurbished one.
[Nexus One General] fescen9:
Either talk to a supervisor or buy a new one and return the old one since it's new. If you have to pay the $45, call them again and talk to a supervisor to get it reversed...
[Nexus One General] drdingo21:
I just ordered a new phone. I will test it when I get it (anyone know if they will deliver on Staurday?). If that one is better I will return my old one. If its just as bad.... I'm not sure what I'm going to do....

If I jack the brighness all the way up its way less noticble (as everyone already knows) but the sensor still doesn't work correctly...
[Nexus One General] pokey9000:
Just got my second replacement AT&T banded phone (1st had dust, 2nd bad pixel). Out of the 3 that have passed through my hands, none have had any tint.
[Nexus One General] drdingo21:
Good. Maybe my new one will be great. My current one has a really bad tint.

I just got an e-mail saying the phone shipped and has a scheduled delivery date of the 12th. Hopefully I will be able to pick it up at fedex tomorrow.
[Nexus One General] NexusDro:
How does one tell if the blue tint on the screen is bad or not? :confused:
[Nexus One General] pokey9000:
I'd imagine a slight blue tint is a good thing. Blue is the shortest lived color in OLED technology, so it makes sense to skew the color balance towards it in a new display. Whites on all the N1s I've had have been a cool white, no more blue than my LCD when I use the "cool" color preset.
[Nexus One General] jasrups:
Just got an AT&T/Rogers N1 today and I haven't noticed a purple tint at all. The screen looks beautiful
[Nexus One General] Bryce2010:
yes this is a problem.

I have a purplish tint. It's especially obvious if the brightness is at low or I'm in a dark/dim room. At first I thought the screen was supposed to look like that but after seeing N1 videos on YouTube other phones definetly have a darker crisper blackness to the UI.

Not all images are effected though - I mean the status bar, stock widgets look off, some apps look off. If you go into the stock news application the background is purpley and there are even faint purple lines at the headings where it says "top stories, weather," etc. The phone app UI looks purpley...

But then other blacks look fine for example in photos or some wallpapers.

So I think it's a settings/software tweak that is needed.

HTC said this was a noted issue of AT&T phones, and to expect a software update soon. The guy at google said he had never heard of the issue.

So this plus the malfunctioning automatic brightness issue sucks. I'm passed the 2 weeks return period and I've unlocked it. Dont want to go through shipping it back anyway... I'm just hoping for an update from HTC...:confused:

other then that, I like the phone a lot

p.s. i took screen shots I was going to post to show here - but when downloaded from my phone and viewed on my computer they look fine not purpley at all... so again I think it's a simple tweak I don't understand why HTC is taking so long to release an OTA fix...
[Nexus One General] NexusDro:
you have the link to the youtube video?
[Nexus One General] Bryce2010:
for example this one the power and news widgets are really black and deep mine is washed out, greyish, purple tint if low brightness

http://www.youtube.com/watch?v=gNOo13Zx42w&feature=youtube_gdata
[Nexus One General] jasrups:
You know what, I may have been too quick to disregard the tint issue and assume everything was fine. After a few days of use I've noticed that my phone's screen has the exact same problems yours does.

That said, I probably wouldn't have noticed if I didn't read this thread but I would still prefer that the screen be optimal on a device that I just payed $600 for.

You said HTC is going to push out a software update to fix the issue? I'm wondering if I should just ask for a replacement device in the mean time. Also, what is the auto-brightness malfunctioning issue you were speaking of?

I want to make sure I try to confirm my device is 100% defect free before I decide to unlock the bootloader.
[Nexus One General] Bryce2010:
@jasrups

turn on your auto brightness. its easier to see if you are in a dimly lit room. see if your brightness level cycles up and down repeatedly.

i think i will replace mine. what if the update never comes? $600+ is too much to settle for that + the off purple color
[Nexus One General] drdingo21:
The purple tint is portrayed pretty well on the above screen shots. But for some reason people still seem to think the ones complaining of the tint are just over reacting.

As I mentioned earlier, I went ahead and ordered another AT&T nexus one - which arrived today. Thankfully, this one doesn't have the blue/purple tint. The pictures actually make the purple tint a little less noticeable, meaning its worse when you actually look at the phone.

Here are the pics. Both phones are on the lowest brightness setting. My old nexus one is on the right.

Here it isn't TOO noticeable. Look at the task bar. It should be white.

Another

Now the following pictures really show how about the tint is. Both phones have the exact same settings (screen wise):

People complaining about this aren't "whiny" or "too picky". Its an issue Google/HTC need address. Among others.

I paid $540 for this phone. I received a defective one, I shouldn't have been offered a refurbished one in its place. I also shouldn't have to buy a new one in hopes of getting a working device.

It more than pisses me off.
[Nexus One General] Zynon:
I guess I'm lucky. My whites look white and I have no dust under the screen. There is definitely a purple tint in the pictures up there.

[Nexus One General] jasrups:
Thanks for the pictures! Definitely eased my mind, I thought I had the tint issue but I guess my mind was playing tricks on me lol. The only issue I have is that at the lowest brightness, there is a purple tint on dark objects like the Power Control Widget and the News and Weather Widget.. I'm not sure if that's normal or not..

My whites seem normal though which is a relief.
[Nexus One General] krabman:
Good pics to illustrate the difference. I will be referencing them tomorrow when mine arrives.
[Nexus One General] Bryce2010:
If at the lowest brightness you see purple on your widgets (like me) then your phone is probably like the purpley tinted phones in the pics! check again turn your phone to lowest brightness, go in a dim/dark room, open white app like notepad or something,mine has a purple tint! I bet with a properly set phone side by side it would look like the pictures...

Does your auto brightness work?

I'm not in the US so can't do a swap... so hoping for a software update... if not will have to do repair :-(
[Nexus One General] drdingo21:
I'm betting its not a software issue...
[Nexus One General] Bryce2010:
I know but the reps at HTC said it definitely was software related only...
[Nexus One General] jasrups:
I can definitely confirm that my phone does not have an issue with the white colors having a purple tint. I just tried multiple apps with a white background (like flash light, gtalk, pulled down the notification bar etc) in a dark room and there was no purple tint! I'm going to further test my auto brightness to see if it works properly.

It seems like its only certain blacks that are experiencing this issue which is weird..

[Nexus One General] jasrups:
Also, you mentioned that since you did not live I the US you were not eligible for a swap.. I live in Canada, does the same apply?

Sent from my Nexus One using the XDA mobile application powered by Tapatalk
[Nexus One General] Bryce2010:
ok well that's good, maybe you're lucky and have a phone that has not as bad purple tint...
[Nexus One General] Bryce2010:
I think so, only US customers can do a swap that's what the HTC rep told me:o
[Nexus One General] drdingo21:
You have to remeber they are saying what ever they can to calm you down and get you too keep the phone. Or maybe that's what they are being told...

I'll tell you this, if it was software -then why isn't it affecting every ATT phone? They all have the same OS and kernel when they ship. Why is the tint still they when I flash another ROM to my broken phone?

It's a hardware problem.
[Nexus One General] jasrups:
Ok so I just called HTC, like you said you can't do a swap unless you live in the US. So the only option for us is a repair, which usually takes around 14 days in total from when you ship your phone to when you receive it back (the repair process takes 14 days).. The girl I spoke with also said this was a hardware issue, not a software problem.. I wonder if they actually know whats going on with this problem, it seems like the reps are telling different people different things..

Honestly the tint is not that bad (for my phone anyways, just the dark widgets) but that said, I want my $600 phone to be fully functional.. Just annoyed that I may have to be without it for 2 weeks..
[Nexus One General] drdingo21:
I dunno. I didn't do a swap. I just bought another phone...

You may want to call.

I'm gonna call tomorrow and return my broken one. We'll see how that goes considering its rooted.
[Nexus One General] jasrups:
The rep told me I could buy a new one and return the old one.. but theres a $45 restocking fee
[Nexus One General] drdingo21:
Yea I would *****.

There is no way I will be paying a restocking fee. I mentioned to my rep that I rooted my phone and he said it wouldn't be a problem.

As far as I'm concerned, I've gone above and beyond what I needed to in order to get a working $600 phone. If they give me too much trouble, I will send them both back and contact my credit card company and start a charge back process.

I won't even get started about how my dock doesn't work. Every time I put the phone on the dock, I have to hold my breath and pray to 7 different gods in order to get the phone to charge.

The weird thing, my old broken phone charged almost every time I put it on the dock. This new one, I have to get on there just right. Its beyond annoying.
[Nexus One General] krabman:
Got my AT&T version yesterday. No tint whatsoever at any brightness. I do have the screen calibration issue though where it misreads presses and you have to turn the screen off and back on.
[Nexus One General] Jonndz:
krabman,

How often do you have to turn the screen off and on ? Is the screen calibration issue persistent ? Does anyone have a Nexus One with no screen issues ?

Thanks
