2 Nexus Ones Side by Side: Significant Difference in Screens!

I found a dead pixel in my first nexus one so I decided to swap it. The new one arrived today and I played with them side by side. The screens are very clearly different between the two. With everything set up identical and the same brightness setting, the one with the dead pixel is very clearly washed out looking with a greenish bluish tint to it. I actually noticed this somewhat before receiving the swap but thought it might be my imagination (the screen didn't seem as clear as my previous t-mobile version.) However, with them next to each other the difference was night and day.
I tried to get a good pic of it, but my photography skills are lacking and this is the best I could get. In person the one on the left (new one) is way better looking. The one on the right (sending back for dead pixel) has nowhere near the contrast and feels washed out, greenish, and unsharp.
So to conclude, if you think your screen might not be as as good as it should be, you may be right. I can't help but wonder if the dead pixel was just a symptom of a larger problem with the screen; perhaps the significantly reduced battery life I experience (compared to the t-mobile version I originally had) is also related to a screen issue. Time will tell...

Update: Here's a better pic. Especially note the green tint and washed out look at the top right where the time is displayed. Look back and forth between them. I edited the color slightly so that what you see more closely resembles what I see. In person the brightness appears the same for both even though the right one looks brighter in the pic.

I agree that the dead pixel could of been part of a bigger problem, but the way the picture came out it appears as if the one on the right is alot sharper.
You should try turning the brightness down on the phones before taking the picture. Also did you lose a flash, or is this effect just from it being at 100%brightness?

I know it looks that way, but it's just a crappy pic. I'll try again later today before I send the phone back. I didn't use flash, and screen brightness had no effect on the difference between the phones.

I actually prefer the the one on the right. The one on the left looks way too reddish/pink. Have you done a side-by-side comparison on the lowest brightness setting and going to a white screen page like Google?

the one on the right kind of looks like the color on a droid screen

The one on the right is far more color accurate. The one on the left looks like my T-mo launch N1, which has blown out reds and makes everyone's faces red in pictures that I take until I move them to a PC with a proper screen.
Color accuracy should be preferred over "pop" and "vibrance", IMO

Agreed, I wonder if HTC received a delivery of defective AMOLEDs from Samsung and just decided to use them rather than return them...

I had a similar issue. My old Tmobile N1 had a the blueish tint (like the picture on the right) but I had a dead pixel.
My new Tmobile N1 has the purple tint (like pic on left) and has no dead pixels yet. I've had them equal amount of time now.
I wonder if perhaps the old screens were having dead pixel issues and HTC decided to go with some different screens?

It could also just be the backlighting. The LED that's being used probably just emits at a higher temperature, eg more bluish-white.

With AMOLED there is no backlighting. Each pixel is its own LED, red green and blue ones, emitting its own light.

I've taken more pics at different light levels. Here's one with the brightness set all the way down. I edited the colors slightly so that what you see more closely resembles what I see in person. The left one does not have a purple or red tint; its colors are correct. The right one definitely has a green tint and is washed out looking. Also, in person the brightness of the two appears the same even though my camera picked up the green tint of the right one making it appear brighter in the photo.
Look at the top right where the clock is displayed to really notice the green tint and washed out look. Look back and forth quickly at the time...

My phone had the same effect of the left one, that is when I first got it. Over time, it starter to slowly lose that red/purple like tint, and the colors became more sharp and correct.

i think amoled screens are somewhat of an organism

I just got my replacement phone from HTC due to dust under the screen on my original N1 (purchased second day of release).
I noticed that the newer phone had quite a few differences, including the quality of the screen. See my post about my observations here: http://forum.xda-developers.com/showthread.php?t=655966

INTERESTINg..How much more battery life did you get with the new one?

Does the screen have a bluish tint in the whites similar to galaxy s3?

have they improved it? I can't find any close picture comparisons.. Thanks.

Looks better, but still there. I guess they're doing it to increase screen life or something, but absolutely hate that.
Once I installed Perseus on my Note II, I could hardly believe I'm looking at the same screen. Looks even better than iPhone 5 after calibration

yeah, but note 2 doesn't have pentile, doesn't it have a superior screen?

It does, yeah. But you can still see the bluish tint there. SIII/IV it's more greenish isn't it?
I have no idea why Samsung doesn't use RGB instead, is it because it isn't yet available for high PPI full HD screens?

I believe posters on here claimed cost reasons. too bad.. I prefer the overall design and build, screensize to handset ratio of the s4, but like the htc one screen..

That might not be apparent in normal vision though. S3 has noticeable graininess, but the pixel density on S4 should pretty much settle that IMO.
And I don't know if they took the screenshot with adobe RGB mode or saturated standard mode.
I love SAMOLED, but just wish if they could switch entirely to RGB. Wouldn't mind paying a few extra bucks either tbh if they implemented that on Note 3.

I don't think they can manufacture FHD 1080p yet. At least not in the amounts that the GS4 would demand at a reasonable price.

Yup, two issues: sharpness and color. It looks like the higher resolution overcame the less sharp drawback of pentile, but color tint looks is still there. need to verify what color mode the phone was in though.

welll, just got back from store. htc one's have multiple dipslay with different WB. but the s4 definitely had better WB in my eyes.

Why is this thread even open ? Amoleds will always have a bluish tint. LCDs always have better whites but suffer on black levels.

if you read my response, you'll see that the One has a more bluish tint than the S4.

[Q] Black level

Searched google and couldn't find user input on the black level. According to that early test by a Chinese site they found black level to be extremely good. Here's the image

Now as the phones reaching users can anyone confirm in pitch black the amoled output? To me that's the most impressive improvement dating back to when amoled first went HD on the galaxy nexus and lost that level of output.

Yes, it is totally black. Way better than S3 and Note 2.

The blacks are the best I've ever seen.
The pixels are completely off, as opposed to previous amoled screens where there was still a light glow.

Wanted to give this Q too I had previously SGS2 and SGS3 is it even better than SGS2 display in the case of black displaying? I was very satisfied with SGS2 blacks... THX

It's much better., Infact it''s impossible to get better blacks as the pixels are completely off.
I was always disappointed with previous phones as in a dark room once your eyes focused the blacks would look light grey and you could see blotches and streaks.
On the s4 you see nothing at all.
If you switch your phone on in the dark all you see is the samsung logo on the screen, nothing else.

perfect THX for response I hope that will have zero stuck/dead pixels

That's amazing. It's pretty poor form that all reviews as far as I'm aware have stated the previous amoleds with that slight glow as infinite black.
Anyway the S4 finally has something I'm really jealous of now. Another question similarly relating, does the brightness go lower than the S3?
?????? Galaxy S3 ??????

I think something is wrong with mine. I have the Galaxy S3 and I would say it's a really dark gray, not quite black. But on the S4, I'd say it has a reddish tint to it when I have it all black in a dark room. I may try and take a picture of it tonight.

I think its every device or atleast very common, but most people havent notice it (atleast not yet) . Ive come to realize its software related so im not freaking out yet. Just posted this in the ATT forums: http://forum.xda-developers.com/showpost.php?p=40841213&postcount=104

It is honestly that black that when I was waiting on a video to buffer in my pitch black room that it looked like the blue circle was floating!! literaly no light on screen apart from the blue circle. It actually looks really cool lol

It is brighter than S3. :good:

It is perfectly black unless you suffer from the bug I posted about here: http://forum.xda-developers.com/showthread.php?t=2256651 .

its pitch black, i tried finding some ink spots/ blotches and black level last night but failed miserably

There is a comparison between S3 and S4 black/grey scale in this video, FFW to 17:10 (or watch the whole unboxing and comparison to HTC One video if you want).
You may have seen this by now, but if not it might answer some of your questions.

Screen lacks color accuracy

Just bought a LG G Pad 8.3 a few days ago after reading the many positive reviews online.
Was especially looking forward to the supposedly high quality screen with excellent color accuracy, as it is also marketed by LG.
So it is with disappointment to discover that my unit does not exhibit these qualities.
The screen on mine has a low color accuracy, especially with reds.
Red colors deviate quite a lot and look almost orange. This results in a poor viewing experience and was not what i expected. Most review videos and photos i have watched does not show this color imprecision.
I suppose i am not the only one with a screen looking like this.
It seems like the screen has not been calibrated properly from the factory.
I feel that i have gotten an inferior product and questions if this is general quality problem with the tablet?

A lot of us have a yellowish screen (including me), I personally fixed it using Screen Adjuster, then the CM 11 built in color adjuster. You can try the color correcting methods I mentioned or use your warranty for a replacement.

I don't really consider my screen as being "yellowish". The whites displayed are pretty neutral i think.
I already tried Screen Adjuster as you suggested, but i have not been able to get any improvement with it. Rooting is not something i want to do for now.
I suspect that LG is sourcing different LCD panels for this device, and that they are not all of equal quality or calibrated to the same standard.
The early production units, among those sent to reviewers, seems to have screens of higher quality with more accurate colours.
Mine is a 402 production.

With the replaced display I also noticed orange-ish red. The white is white, black is black, no lightbleed or yellow-ish screen. I compared some pics on a professional Dell U2412M IPS monitor and the red was really horrible orange-ish on G Pad.

Thank you for sharing your experiences. Please cast a vote in the poll.
Could you perhaps show a photo of your screen?
I think that LG at some point changed the IPS panel used in G Pad 8.3 for a different one. After all of the problems reported with the early productions this would seem appropriate.
It seems, though, that the color calibration of the panels have gone wrong in the process.
It's regrettable, as i otherwise like the aspects of the tablet. I guess i will just have to live with it or buy something else.

I think that the major problem is the gamma curve setting. If you can and know how to, try the kernel posted in the Android development section, which has improved (normal) gamma, although it has possibly some other minor issues unrelated to the display, but nothing unrecoverable - you can flash back to stock kernel easily.
I am currently running with it so you can rest assured that the tablet is not going to die, or something
P.S. Maybe I spoke too soon - had to revert back to the stock kernel because I got apps crashing and also some spontaneous system reboots with the suggested kernel, probably due to the additional tweaks in it, apart from the gamma tweak.

Although I do not have any orange issues, it is true the colors are not perfect, but nor are they bad, at least on mine. My monitors are all color-calibrated and I too have made comparisons. You can use Trickster Mod to adjust the colors, but the gamma really requires the kernel of the ROM in my sig. Bear in mind that though Dell produces a nice monitor, if it is not specifically color-calibrated, then it too is not a reliable source.

Z3 camera worse than Moto G 2014?

Today I tested canera performance on my Z3 and my brother's Moto G (2014). The result scared me a little. I hope it's just me who thought the moto G ones were more vivid... what do u guys think?

Z3 captures the colors as they are in real life. Some would say that's good, but I'd rather get more vivid images instead ?

That's why you edit pictures afterwise.

It looked more like the z3's pics. The Moto saturation is a little high.

Yes, sadly.

Try the Camera FV-5 apk. Not that any particular app makes the pictures look better but it gives you a DSLR complete control feel to it. Also the Aviary apk (free) has some nice simple touch ups for pictures.

Whats wrong with the pics?
The Moto pictures look as said saturated blurred and low in quality.
The camera of the Z3 is the best one I ever had. Even in low light enviroment it makes awesome pics.
Compare some pics in the evening when u are watching tv with lights out and be happy to have a phone with such an awesome cam.
The Cam and the Display are the 2 things that keeps me away from installing CM.
If u want more colors play a bit around with the special effects f.e. hdr.

So, I wasn't there but this is what I interpret the pictures as.
The Moto G pics aren't really over-saturated, they just lack dynamic range (difference between dark vs light areas). They essentially tuned the sensor so that if this sort of thing happens, it chooses the brighter side of the scene. The leaves and darker areas can't be recorded as dark as they actually were, so it chooses to make the overall picture just brighter. Sony does a much better job of capturing the light areas such as the concrete and also the darker shades and leaves. The other difference is white balance, the Sony chose something a little cooler, and the Moto warmer. Without being there, tough to say which is more accurate but from the pics I'd say the Sony got it right.
Easy fix, force the Sony to overexpose or use something like pixlr to boost exposure.
Second picture is much of the same, the thing that jumps out is the red colors. In the moto it looks orange, in the Z it looks much more red. Again, if I had to guess the Z got it right.
Now, this is all great with plants, rocks, and garden hoses, but what happens when you take a picture of people? Those Moto pics are going to look off, like people's faces look like cake and lack the proper color it needs.

Thats kind of the while point of "point and shoot". I should be fiddling with settings when im trying to capture that moment. Superior auto setting is an absolute garbage

Xposed module changes superior auto to 20.7 mp makes a big difference

Seriously what is wrong with you guys.
Have you ever used an high quality cam?
In every shop there are phones where you can test them.
There are more tests in the net as you could ever read in your lifetime.
So if you don't like it don't buy it.
Should sound familiar as an iPhone user xD
Have just done a few shots but I'm sure you can save your favorite settings.
If this is too mich work to do I would suggest to sell your Z3 and buy an Moto or similar and stop annoying us.

I personally think the z3 camera is one of the best out there not hard to use manual mode

Sorry. I should've quoted the person who said that that he prefeerd the more vibrant colors over the more accurate. I meant that if you want it more vibrant you should edit it so and let the original photo be correct.

I use 8MP on manual it does well, it's just "Superior Auto" that sucks.
