[Q] Does this look washed out? Is it a faulty screen?

Take a look at this screenshot of my phone. Does it look washed out to you? I think it's horribly washed out. I had a serious hardware issue with my phone (the microphone failed completely - I even reverted to 100% stock and the issue persisted).

So I had a warranty replacement and this new phone's screen seems horribly washed out. I took a screenshot which I've posted here, but I'm not sure if it does justice to how bad the screen seems to my eyes.
The background looks gray but is supposed to be much more black looking (Tapatalk dark view).
Should I request a replacement due to screen issues?

You do realize that the screenshot will absolutely show nothing that the physical screen is showing you? It's effectively showing a "video out" of the screen. Its showing what the phone hardware is sending to the screen.
You have to take a picture of the screen with another camera...

Looks fine on my iPad 2.

Looks perfectly fine on my notebook too. LOL.
Ya do what the 2nd guy said.

Sometimes my Tapatalk looks like this and other times the app is actually black. Are you saying my screen goes from washed out to not washed out?

I think what he is seeing is the HW acceleration gradient present in ICS.
To the OP, if you go to your settings, do you see the same gradient running from the bottom of the screen and getting progressively darker near the top?

I would recommend using Franco's kernel until voodoo comes out. To me the "hue" is slightly yellowish on stock. Using Franco's kernel it's much nicer.

It isn't washed out. That gradient you see means hardware acceleration is currently enabled.

What are your color control settings

Can you please share your settings

Every screen is different.
Mine might look like crap to you...yours might look like crap to me.
But -10 1 10 for me.

- Google

can anybody confirm whether color control settings resolve the following issues:
- black clipping (blacks in videos showing pixels and artifacts).
- tint on half of the screen.
- color banding.
- grainny screen.

No they don't, at least in my experience. I have the same screen issues as you do and have tried millions of kernels and color control combinations imaginable. I have had 2 replacements thinking it's a hardware malfunction but still the same screen issue. I believe it's because of the Pentile display. Definitely looking forward to upgrade in October.

thanks for the confirmation.
i'm on my 3rd GNex. it has no "yellowish tint on half of the screen" but black clipping. the 1st GNex had no black clipping, but a severe yellowish tint on half of the screen. this is obnoxious.
i can't even watch youtube on my $450 phone.
it shouldn't be a pentile issue. the galaxy S had a pentile display, right? the upcoming galaxy SIII uses pentile too. also, what can justify the perfect screens in some GNex? it is poor quality control, nothing else.
i'll go for 4th replacement. after which, i'd be done with this nexus curse.

[Q] Color Control for Note 2?

Hi,
I would like to know if it will be possible to implement Color Control (as used in many Galaxy Nexus custom kernels) in custom kernel for Galaxy Note 2?
Here's a link (it worked wonders on my old Galaxy Nexus!):
http://forum.xda-developers.com/showthread.php?t=1521195
My Note 2 has a heavy green/yellowish tinted screen. The problem is much more pronounced than on my old Galaxy S3, which actually was quite bad, too...
Otherwise I have to return my Galaxy Note 2

This is a comparison between my calibrated LCD and my Note 2:

I would LOVE to see something like this ported to the GN2!

I got my replacement today. Still the same problem (at leaster better build quality). I've compared mine to other Galaxy Note 2, every single device I have seen had the same issue. So I guess there are many GN2 with that issue out there.

This is a screen shot from my note 2. Is there something I'm not seeing? What's the problem?

Mine doesn't actually appear to have any tint to it, but one of my hobbies if photography so I'm picky about colours

Do you have power saving mode on? There is a screen setting in the power save menu that tints the browser. Also try to use the "dynamic" screen setting instead of natural or the others. That fixed my tint.

One thing you are not seeing is that a screenshot can never represent a displays color reproduction. As you are eliminating the actual display and only looking at the image as it was rendered in the software. All screenshots from all devices will appear the same, however photos of the actual rendered image on screen will show variations. Using a calibrated display as a reference is the only way to have a solid comparison, just like the OP did. If you want to contribute, do the same.

[Q] Yellowish tint near bottom of the screen

I just picked up a 2013 Nexus 7 this weekend as an upgrade for my 2012 model. Seems like a solid upgrade so far but I'm bothered by one item and it's the yellowish gradient toward the bottom one or two inches of the screen. I need to tilt the device maybe 15 degrees away from me to get a more consistent color. If I rotate the device 90 degrees counter-clockwise (camera now on the left), I can still see the yellowish darkening on light screens on the right. My 2012 model has consistent color throughout. I found a number of posts regarding people complaining of about a warmer color to the 2013 screen but haven't seen anything describing the gradient I see. It's rather annoying when reading webpages or ebooks with a light background.
Anyone else see this on their Nexus? Did it improve with time?
I tried to take a couple of photos but my camera doesn't seem to be doing a good job of picking up the colors.

Common issue
I returned mine (because of it) and got a new one which had exactly the same thing.
I also checked out a friend's N7 and had the same thing.
So I guess it is a normal thing. It is hardly noticeable and only on white background.
(Most panels have some kind of uniformity issues. I checked an iPad 3 and had some other issues...)

Thanks for the feedback. This is actually driving me nuts and I'm going to take it back to see if I can get one with at least less of the effect. Mine seems to be worse than the display model in the store I saw today. If they can't give me something that's equivalent in color consistency to my 2012 Nexus 7 then I'll return it and just stick with that.

If I were you I wouldn't bother.
In the store there are other ambient factors that may trick you in believing the store's sample is batter. But it will not.
3 samples I checked are exactly the same...

My device have yellow tint to. How to fix? "Screen adjuster" and other not helped for me.

I don't believe that this is correctable with software. I ended up getting a different tablet altogether and even this 10" one has the same issue. Guessing these panels are all coming from the same manufacturer....

[Q] About those viewing angles...

Hi to all
I'm pretty new to the tablet market and I just bought the note 10.1 2014. I'm in my first 14 days where I can exchange/return my tablet and I want to make sure everything is ok with my stuff.
I've read countless online reviews before making my choice and, as you all know, one of the strongest aspect of the note 10.1 2014 is the display. Most if not everybody is praising the resolution, the colors, minimal color shifting, brightness and the viewing angles. Now, I want to make sure my understanding of lcd displays/viewing angles is good.
My tablet's display is gorgeous... when I look at it straight at it. I have the minimal light bleed on the edge which only shows on black and has 0 impact on colors which I'm ok with (all demos in stores are the same so...) As soon as I tilt the tablet though (vertically or horizontally), colors become very dull. Actually, colors do not shift but everything becomes dimmer/duller. Now, I suspect this is normal behavior from a backlit LCD but still, I keep reading reviews stating the display is gorgeous and bright even from an angle which is not 100% right for mine. I've tried to look at videos/pictures online but most people doing reviews actually setup a camera right in front of the tablet and barely move it once it's turned on so it's not helping me. So when you guys are saying the tablet's display stays vivid and colorful from every angle, are you getting the same kind of behavior my tablet has and are not talking about this because this is normal behavior for an LCD display or is my tablet's display defective?
Thank you very much in advance for your cooperation. If needed, I could take pictures.

As is typical of the Samsung displays, the viewing angle stability is great. The colors remain stable regardless of the viewing angle and we did not note any great loss in brightness.

Thank you very much for your reply. Well, I guess my tablet's screen is pretty similar to the test unit provided in the review. My definition of stable brightness and colors is pretty different from the behavior of that display But to know my screen behaves normally compared to other tablets is good to know.

Just enjoy this tablet..Don't spend hours looking for problems that arent there. This tablet is wonderful , I have had mine since December with no issues at all. I'm rooted with tons of stuff on mine. Most of the problems I have been reading about are people with way too much time on their hands. Have a beer , and love your tablet!!

Don't get me wrong here, maybe I did put too much emphasis on the display and I'm sorry about this. I love my tablet too. I'm just discovering the power of the tablet and the S-Pen, the integration is pretty amazing.
Cheers
