Galaxy Nexus grainy and vertical banding screen!

how many have devices like this? It doesnt seem to disappear on mine until about half brightness up.. and even there i can slightly tell. is this a problem on most phones or only some? Also with light usage i'm losing over 10% per hour, doesnt seem right at all

All AMOLED screens have that issue at low brightness, it just varies from phone to phone. Give it a few charge cycles before you start looking at the battery. The battery on my Nexus drained extremely quickly when I first got it but it's been lasting longer and longer with each passing day (3 so far)

My screen is the same, you need to be at half brightness to get a decent image. Auto brightness in full darkness makes you think that the screen is totally broken.

yours has like bands of a different shade too? mine has one thick one on the right of the screen and it's pretty annoying.. about to go into the city tomorrow to exchange it but if there all like that then i dont know

I went in to the store, and they said that they wouldn't switch it out.

Mine looks fine at lowest brightness. I use mine mostly at.about 10% brightness and look great.

Yes ! I thought that mine was also broken. It is good to know i am not alone .

can we get a screenshot?

Would it even show in a screenshot? Yes, it's AMOLED... that's the way it is. More than worth it.

It wouldn't show in a screenshot since this is a hardware related issue. And I don't think it's normal if it has brighter spots like explained. Mine isn't as smooth as you would expect either at lower brightness levels but it is not like explained by the OP.

All SAMOLEDs sacrifice clarity and color representation for slightly better black levels. Just the nature of the screen technology. All 4 Samsung models (and all 7 phones) I've come across have it.

in denial???

I've never seen the banding effect before, and this is coming from someone in a household with two out-of-commission Galaxy S', two GSIIs, a Focus, and my Nexus. The PenTile screen door effect can get to me if I'm looking for it, but that's the only SAMOLED issue I'm familiar with.

I actually like the slightly grainy look mine has at lower brightness levels

Would Voodoo Control be compatible with this? It was an awesome feature that my Nexus S had!
Sent from my Galaxy Nexus using xda premium

Not only is mine grainy at low brightness, it also has a pink and green tinge (in opposite sides of the screen)
It doesn't seem to happen on the 1st gen AMOLED (Nexus one, not grainy at low light) or S-AMOLED (Galaxy S, it did have an overall blue tint, but it was on the WHOLE screen)
Not completely noticeable, but would have expected better. At 40% or higher, its barely noticeable.

Got the same problem 40-50% and its barely noticable, any lower and i can see much distortion.
I know its a hardware thing but is this something that might be fixed with a future update or are we stuck with this?

The screen will look grainy on white/grey backgrounds at lower brightness settings, but there should not be any vertical/horizontal banding on the screen.
My first phone had a vertical bar of banding going down the entire screen, and bothered the crap out of me. Went in this morning and had it swapped with a Nexus that has no issues. For the price that we're paying for this phone (especially those with International unlocked imports) it better be perfect.

yup, i only ever see it in one place (the grain), and thats on the store before anything loads (an all gray background). Don't see it on white or anything else... that i know is pentile.

Galaxy Note is similar at lower brightness levels, must be AMOLED.
iPhone 4S is best if reading at lowest brightness levels is very important,
but in brighter light the Nexus and Note look amazing.

Question about screens brightness

I recently got an evo lte for my son basically to use as a small tablet. I cant help notice that the screen is way brighter. Now ive always seen the evo people use this as a defense when someone says an s3 is better then the evo but i just always brushed it off. Its not just mine either my gf is the same way. The brightness on both phones is turned all the way up. Ill post sy side pics shortly
Sent from my SPH-L710 using xda app-developers app

Its well known. Different screen technology. I have both phones and was one of the folks that prefer the EVO screen, at first. Now I prefer the deep blacks of the SG3.

Trade-offs.
Personally, I don't use my phone outdoors much in the direct sunlight, so this definitely isn't a requirement for me.
Bear in mind the SGS3 uses actually a technically superior technology to LCD... an LCD has a backlight, with pixels that are flipped on and off and the backlight shines through them. So black couldn't be farther from black - it's grey at best, as you could use an LCD screen to light your way down a darkened hallway even with a fully "black" screen. This also makes contrast ratio pretty bad.
The AMOLED (key letters in there being OLED) display by contrast has pixels that light - little LED's. There's no backlight, so black is black - like phone off black. It's a much, much better picture.
I have my brightness set to "auto", so I haven't noticed it being any dimmer than my older HTC phones, but I definitely appreciate the picture and contrast.

I guess i just love my s3 so much i thought it was invincible lol

LG I want my yellow back

So, I love everything about this G Pro except one thing it was bought for. The display of it is a disaster. I mean it's the worst LG smartphones' display in some years. I prefer to use indoors @ 60% brightness with autobrightness on and in this setting everything looks so dim, grey and almost unseen-able. Especially yellows, I mean there's almost no yellow colors @ all even at 100% brightness, but at 60% it's even worse. And to not be a windbag I've snapped some comparison photos of G Pro next to another LG smartphone, which has, IMO, the best screen ever. When you hold them both in hands its no question which one you'll keep to yourself being forced to choose
So if LG will continue to mistakenly set their display's color temperature to 10000K, I confess my next phone would be HTC or even Motorola. I don't want to see ppl faces of corpse skin colors, and green everywhere where yellow supposed to be

Your comparison phone is over-saturated and blown out. I am looking at the images on an very expensive and calibrated IPS at work. Neither phone has it right, but the G Pro is closer in comparison. The G Pro certainly is cooler in color causing the yellow to become green-ish. But comparing an almost green image looking for yellow is silly. It won't make people look like corpses... you can test that too, with pictures of people... odd you didn't include that in your image set.
Edit:
Wait, hold the phone, there is one person in your test, and they don't like like a corpse... imagine that.
Edit 2:
Wow, if you really can't see that the G Pro looks better, you need to have your eyes checked.
Can you really not see how **** the other devices screen looks?
What ever you used to take the pictures is very grainy too... just fyi.

You don't see my point or don't want to. Look on your expensive IPS at this image http://www.google.com/search?site=imghp&tbm=isch&q=5403393757_b5b17ea28d_o.jpg You see? There's tons of colors in it. Then transfer it to your G Pro and open, it made all color turned into shades of blue. It's intolerable. Well, Nitro also make this image bluish, sort of, but in way no as blue as G Pro
Nitro has its fallacies, of course, it can't show every possible color in the Universe, as I remember it covers 87% or 97% of sRGB when G Pro covers 99% sRGB. But Nitro has col.temp set around 6800K and all images looks true to life. I haven's seen one person who was dissatisfied with that screen, even photographers. And G Pro has around 9000K, it's way too much, the white percepted as grey, yellow almost gone and turned green, oranges turn into cherries and etc

No, even there it has slight green tint, and white below is blueish, you must have good IPS monitor or mobile display at hand to compare. When you compare the difference is stunning and eye-popping.
Also, in original post the second picture is https://play.google.com/store/apps/details?id=com.gombosdev.displaytester showing yellow on both devices and in archive all other main colors like white, red, blue. My concern is yellow and white because the white is what you looking at most of the time

No, I don't think so. Every other youtube review unit had the same cucumber-blueish tint on white background, EVERY. So it's LGs settings that are faulty.
Do you have any spare phone at hand? Like HTC One? It almost perfectly calibrated. Go to some place, put the same white or yellow wallpapers on both devices and compare which unit will be more eyepleasing and easier to look at. I'm sure the other phone than G Pro will be
We're waiting for anandtech review, pity that he doesn't even look at G Pro, it even prefer noname Oppo Find5, it means bad for LG, it's bad marketing that even anandtech doesn't review their phones

I have yet to find a single review that had anything negative to say about the display on the Pro. The worst comment is that it's almost as good as S4/One. I even saw the color accuracy praised in a review. I don't doubt there are likely exceptions, but not in the ~10 reviews I browsed through.
My co-worker has an HTC One and while due to size his screen looks crisper, the Pro looks damn good otherwise.

Checked out that link, everything looked perfectly like they saidit was supposed to even at lower brightnesses...maybe u just have a bad screen, i watcj lots of vids and pix on mine and they all look fine

"The screen is very nice." First sentence in what you quoted. Not a single one of the reviews mentioned an issue with the color balance. I personally do not see an issue with the color balance. A number of other people in this thread don't see an issue with the color balance. I definitely saw an issue between the two in the picture, but my phone doesn't look like that and from the sounds of it.. neither do most of the other people's. So, if everyone else is telling you it's your phone...

Why are you so effing worked up over this? It's not nearly how you describe. Almost everything you have pointed out is either slanted/strategically chosen quotes from actually solid reviews or pure hyperbole.
Just sell the flippin thing and move on, your exaggerated criticisms are going to scare off developers that we desperately need.

Nexus 5x display yellow?

Hello there, could you notice the display of 5x is yellow? From the unboxing and review videos, i can see all of them seems quite yellow when compared to other phones.
Could you give your comments on this? If there are photos provided would be appreciated.

That's just an illusion caused by the camera as mentioned in the Pocket Now review, my display looks fine.
Sent from my Nexus 5X using Tapatalk

I have two 5Xs one in quartz and one on carbon. My quartz has a much cooler screen than the carbon. My carbon's whites looks more of an off white and overall the screen appears more dull and not as bright as the quartz. Colors are not as saturated in my carbon as on my quartz one. My quartz one was made in Oct 2015 and my carbon in September

my first instinct upon powering up my phone and looking at the screen was "damn, this looks really yellow". at this point, I think it's combination of two things: the first being the different in color temperature between this screen and my HTC M8, and the second being tha tthe screen is just flat out a bit warm. After a couple days of use (i got my 5x on friday night), it doesnt feel nearly as yellow as at first, and i really being it's just a matter of what your eyes are used to, but it certianly does have a warmth to it that i was not expecting. there's also been a bit of chatter on teh tint to the screen, so it seems this just varies slightly from phone to phone. I'll say this, I certainly didnt buy this phone because of my faith in LG's build quality or QC. That (and, sadly, Sense) will be the two things I struggle most to move on from when leaving my M8 behind.

If you've ever had an lcd screen calibrated for color accuracy, you'd see that warmer colors are actually more "natural" and realistic than the cool/blue tones you're accustomed to seeing on most lcd's

Yeah you're right. I've had LCDs calibrated (TV, monitors, etc), but never a phone. Know of any good ways to do that? I know of apps that let you tweak the color temps and such, but never to truly calibrate it.
And I just realized I forgot to mention that now when I look back at my M8's screen, it looks quite blueish and sterile. I have no qualms with the 5X screen as I see it now.

It looks much better for the quartz one. It provides a little evident that the latter one produced in Oct is better. The unboxing videos are the first batch devices. Keep an eye on this to see if they really improved for the latest produced devices. Thanks for the sharing!

I just compared my N5X with an iPhone 6. The iPhone screen looked so bright and white/blue(cool). It hurts my eyes. But N5X is very warm. White and balance setting in cameras probably, making it a lot worse. It's much calmer to my eyes.

I have read that a higher kelvin white will keep you up at night, some are saying these new LED bulbs with the whiter whites are not good for the brain/sleeping. I noticed the whites are not as blue as another device, but compared to my Moto X it is not as yellow as the Moto X. When using the 5X and not looking at another device the whites seem very white to me.

I'm returning mine for a replacement or refund not liking the yellow hint to the display I have read Google have replaced handsets if purchased from the store due to yellow screen as I got mine from cpw im within my 14 day return as only got Sunday so shouldn't have any issue I came from a Galaxy A3 and screen was much better

Yes it is a tad warm when compared to my relatively high end Dell monitors that reviewers claim is about 6300k.

I'm no expert and I don't own a 5X but did any of you guys try turning off the adaptive brightness and seeing whether the screen went back to normal or not? Just a thought.

Yeah, sounded like there was a legit problem I just didn't see it mentioned so I thought I'd ask cause I was thinking of getting a 5X myself. Thx.

It's a good phone don't get me wrong but could of been better I think for price of the 32GB you can have a Moto X pure both are not perfect but X pure bit more bang for buck although I miss the lightness and fingerprint scanner of the 5x I do how ever love having a more premium device with decent screen and camera and turbo charging is awesome feature for me if the 5x had a better screen and extra GB of ram it would be a keeper I think

Ok here are some comparison pictures.. My original Quartz 5x, then the yellow tinted carbon 5x, with my replacement carbon 5x and a few shots comparing both the yellow tinted carbon and the replacement carbon with the 6P. Now seeing all 3 5x's side by side my quartz seems to have a redish tint compared.. odd.. I'm happy with the screen on my replacement carbon
http://imgur.com/a/1mHv4

Mine looks just fine. It may have a slightly warmer temp than my S6 edge screen, but that one almost looks too blue. The colors on my 5X look more natural. Maybe I have a good one?

Wait for custom kernels with color adjustments options. It's simpler...

LG G7 Screen Grainy effect???

Am i the only who has noticed like this grainy effect on the display if you really focus on it. Its more noticeable on white backgrounds

? You're not alone, my screen is the same- full of very faint horizontal banding. I thought at first it was due to the cheap plastic screen protector I had on it. While I need to look closely to see it, it is quite annoying. In the BBC news app the red section at the top of the screen is where I first noticed it. I love the phone but for all the shouting LG has made about the screen, this is not acceptable. Personally I'm not sure it's a fault, rather LG's inability to produce a half decent phone screen- look at the issues people had with the v30/Pixel 2XL's screens and my G4 was a hot mess of image retention after 6 months. ?

Can you try to check it with a different wallpaper to see if it is due to the app or background

My screen is perfectly fine and crisp.
