Amoled screen question...

Hey, I saw an app around that uses a pixel or whatever on the screen ad an led notification. Apparently it was stated that no energy is consumed when the pixels are black but upon viewing a pitch black image on my Vibrant in total darkness , I can clearly see some sort of ambient back lighting that makes the screen visible. Maybe I'm just picky but.... What gives?
Also, the faint screen appears to have inconsistent areas where one spot would be brighter than others.

could that "backlight" be coming from the capacitive buttons?

Dude, maybe its all the drugs you did in the 60's. I am looking hard at the screen of mine and the black is black best looking screen i have seen

The room has to be pitch black in order for you to see what I'm talking about. The capacitive buttons are not on so I dont think its that leaking onto the display. The display is very good, no doubt, but I was just questioning whether it really uses no energy for displaying black on the screen.

Hmmm!!?? purple-ish screen tint on lowest brightness on my new NS

Well I used to cause a big fit about the N1's HTC would warranty swap me because of this issue. The first N1 I purchased didnt have this problem. I just bought the NS today and right away I noticed the same exact issue. Is it safe to say that maybe this should be considered a normality rather than a defect?

Its actually the Amoled tech itself...It cant reproduce whites perfectly so they come out cool....thats why its off a bit but in return you get exact blacks
Lcd's are opposite...you get real whites but no real blacks.

It shows up in certain shades of grey, like in contacts and in clock dimmed while set on lowest brightness setting. The whites and other colors display fine.

Yeah i saw that too but thats the OS thats doing that so you should be cool

Is it either on the bottom or top? I have watched a YouTube unboxing video clip says that when you browse with your nexus s to the top of the page, or the the lowest of the page, it will actually dimmed darker. This is to let you know you have reached the lowest or highest of the page. You couldn't scroll anymore .

No, it has nothing to do with scrolling. It's exactly what I've said. Also I'm pretty positive its not a software issue. It's definitely the display. It must be either new materials Samsung is using for there displays or a calibration issue!

I also noticed this today, the purplish tint while on lowest screen brightness in a very dark room. If you bump up the brightness slightly, it goes away.

Nothin for me. No tint.

For me when I have the screen off I notice there is a purple tint to it compared to say a vibrant maybe that is the cause of you're problem

what i'm speaking of shows only while the screen is on.

This is right on the money. Same exact issue with my N1 and now i see it with the NS. I notice this on the N1's because my very 1st purchased unit displayed perfectly without any kind of discoloration after dimming the brighness below 50%. Soon after I warranty exchanged that unit for another, I recieved one with the tint issue. After I exchanged a couple more times, I recieved another without the tint issue but the touchscreen problem was much worse than the others i've had so i sent that one in. After that, i havent received one without the tint problem yet. I bought the NS expecting not to see this problem again and lo and behold, it surfaced as soon as i dimmed below 50%.

I checked out the demo phones, and every one had it on the lowest brightness setting. I think it has something to do with the new colors in the OS. If everything was black, it would be harder to see, so they use a little purple to differentiate when on a low brightness setting. You dont have to turn the brightness up much to make it go away

The issue I'm speaking about, it doesn't literally "go away" in the manner you might be thinking. Its just that certain shades of greys are affected by it. Here's how to test for it, goto a dimmly lighted area and set the brightness thru the power widget to highest. Next, goto the dialpad on your NS, and notice the bar topright below the menu tabs, it should be grey. Now go back to your power widget and switch brightness to lowest setting. Go back to the dialpad and look at that bar again. It still should remain grey no matter how I adjust the brightness levels, but instead it'll shift to a light purplish hue.

It's because of the amoled screen uses the pentile sub pixel layout. I thought this was well known. All Samsung amoled screens do this as the all use pentile sub pixel layout, which many people hate as the feel its not as good as the true 3 sub pixel layout screens. And It's true it is not as good, but I still prefer it over non amoled screens, crap pentile and all.

Yes I know about the subixel stuff with the amoled displays, but I have to disagree with you as far as all of them display this way. As I've mentioned before, I've had 2 N1's without this issue. I'm gonna go back to BB to see if they can open a couple so that I can do some comparisons.

As I said, mine is this way too, but went to 2 BB's tonight and checked out the demo models at each store. They both had the weird purple tint as well, on those few shades of gray, like you pointed out. I also watched the Engadget video review and could see the purples on their phone too. I think all the NS's are like this, just the way the screen is. Perhaps in a software update, they could tweak the colors a bit and fix it.

actually
this is not true. i had to go around 4 Galaxy S screens and finally i was able to find one without pinkish color in it in low brightness.
if you want to tell if you have pinkish hue. download a solid dark gray wallpaper. turn the brightness to low. if you see it pink. then you have defective screen. i repeat. its a defective screen. dont justify your self with it.
i went through 4 galaxy S and i was able to find one where white is actually white and closer the the cool blue. not a friggin pink
and its not amoled screen either. the iphone 4 is same issue. go to macrumors forum and check for your self.
i went through like 6 iphones to get one with cool blue and no yellow tint in it.
the difference is light and day now when i compare my iphone 4 to my other friends.
if you have an OCD with this " because i do. i have OCD for light leakage, same black level the whole screen, yellow/pink tint on the screen in low settings "
the whole phone to me is nothing but a big screen. if they f*** that up. then its useless

its not a software problem.
its hardware issue. when my phone with pinkish tint along with my brother one didnt have one, i thought it could be a software issue, and we even both implimented the voodoo fix : galaxy S : and still looked different.
its a hardware issue. and i really think you need to change your phone. because if you are like me, who cares alot about his phone, then once you see someone with a nexus S and you compare the whites and the gray colors on both phones. you will be one sad panda.
hell put the brightness up to the max even. you will still see the difference in white level between a pinkish/yellow tint screen and cool blue one. its not even funny :/

Yes I'm definitely OCD'd on this issue lol. I'm still not total convinced that this a defect yet. Ill be going to a few BB's today to do some comparisons. If I do find one without the tint, then cot dammit, shame on Samsung for allowing this to slip thru on these screens again! Ill report my findings later.

My NS suffers from this horribly on top of the bad touchscreen issues it also has. Def. a defective unit

The overall Nexus experience

A few of my main issues with this phone are as follows:
-green tint on screen
-somewhat insensitive touch sceen (Evo screen is a lot more responsive and less prone to miss touches)
-very short battery life 5-6 hours of my typical use) My Evo battery lasts twice as long.
-radio issues
-cheap, slippery plastic (prone to scratch and fly out of your hand)
-speaker can in-call volume not very loud. (though it does sound good, imo)
Overall the Nexus does not have that premium feel that a "Google Experience" flagship phone should have IMO. The LG Optimus (free on contract) feels better, and has rubberized case. If LG can do that on a cheap entry level Android phone, why can't (money bags) Google?
Obviously these are just my opinions, but it seems like Google will lose out on sales when their *Flagship* phone feels cheap, but costs $550 off contract! Expecially when it it sitting next to phones which feel a lot more sturdy, do not have green/yellow tinted screens, etc.
I never liked the Epic because it feels cheap and hollow. The Nexus does not feel hollow, but is does feel just as cheap. Hopefully for the next Google phone they will get a better hardware partner!

The biggest thorn in my Nexus S experience still remains the typing, and more specifically the double-letter glitch with the first letter of words. It's ridiculous. I'll get sentences like this, "Hey Bob, hhow is it going ttoday?" Frequently. Then sometimes it'll even repeat the first two letters of a word, for example, like "ththis." This becomes especially obnoxious with two letter words, like "I'm walking toto the park."
It is a known issue, but Google has yet to address this: http://code.google.com/p/android/issues/detail?id=14755

I'm pretty blown away by your post.
I've never owned a phone that feels as nice and classy as my Nexus S. It makes my old Evo feel like a side-show freak compared to my Supermodel Nexus.
My screen looks absolutely spectacular.
My battery life ABSOLUTELY BLOWS AWAY my Evo battery life. I go all day (and sometimes into the next day) on one charge STOCK, whereas I had to undervolt and mod the **** out of my Evo to get maybe 10 hours.
I did find typing easier on my Evo, but I've always attributed it to the larger screen.

I agree with all the points here. I've only had my Nexus 2 days but it's far superior to the Evo. It's faster, smoother, slicker, and has noticeably longer battery life. My only complaints are the lack of a notification light (which, honestly, I've not missed at all) and low external speaker volume.

I noticed the strange green or yellowish tint to the screen as well. I noticed if you turn the brightness all the way up it helps. Or if you're on CM, use a theme that display battery and signal in a color other than green in the status bar.
My one biggest complaint is really how noticeable pixels are on letters and some images. I was looking at some other phones and I found the screens to look a little more crisp. (Is this attributed to a higher resolution or PPI?)
The next point that bugs me is the body. Yes, it's gorgeous, yes it's light and easy to handle... but it -does- scratch and ding easily.

In terms of differences in screen colors (tints - some are green, some beige, etc), battery life, etc., these things go to show the inconsistencies in this cheap Samsung hardware.
I know it is easy to pick up a new phone and feel like wow, this thing is awesome. But once I saw all the issues with this Nexus, and went back to the Evo...while heavier, the Evo feels much better, and is a much better experience overall. From typing, to sound quality to screen sensitivity, scratch resistance, LEDs, larger screen, etc. The only thing I really like more on the Nexus is the camera - while lower resolution is has less noise, and the edges of the lens are sharper than the Evo's.
While I do not care about 3D images, I am now looking forward to the Evo 3D, which is thankfully narrower than the Evo 4g.
Anyway, to each his own. I am not trying to convince anyone to agree with me. Just stating where I stand.

It's because of the pixel matrix. AMOLED is a fundamentally different technology than LCD - LCD panels push a white backlight through a grid of color-changing pixels whereas AMOLED basically consists of a grid of LEDs that emit their own light. It's a very new technology and obviously it has a bit of room to mature.

I agree that the pixels are visible for some reason on the Nexus. It is not a deal breaker, but it is surprising when you read so many people saying how awesome the screen is. (to answer your question, higher resolution would mean LESS visible pixels.)
And while turning up brightness does help with the tint, my battery reading states that at times the screen is consuming more than 80% of the battery! ouch. Right now it says Display=66%)
And many reviews refer to the tinted LCD - it drives me mad. I am a photographer, and so maybe I am more sensitive to it than some.
I think the body of this thing would be helped hugely if if was the same shape, weight and size, but made of better materials! And the slippery plastic makes it NEED a case according to me, and with a silicon case it is LARGER than an Evo. (same width, but taller... Better build materials would solve the need for the case)

It only bothers me when the screen is on its highest brightness setting and when I'm reading white text on black. Otherwise, I think it displays things pretty nicely. I only notice some pixels around a few images. I bought this on May 14th, 14 days short to exchange it out for an Evo3D. I'm kind of on the fence about it though... On one hand, I think it's a really nice phone (but maybe it's not for me?) On the other, I can't picture myself really needing an Evo3D, but if the display and signal are better... who knows?
(Off topic: If I return or exchange this nexus do I have 30 days with the new phone? I may get a temporary if I decide to do that)

Gmap, yes your 30 days starts over, but they may charge you $35 for "restocking." Though there will probably not be a fee if you exchange it for the same phone.

Thanks dude! I'll have to look around at other phones and compare the screens. Does the 3D screen on the EVO3D compromise the quality at all?

The 3d screen will be more contrasty and higher resolution than the current Evo...and the new phone's shape is more narrow as well.

It's really starting to grow on me. Don't get me wrong, anyone, I think the Nexus is a great phone but maybe not for me.

you can see pixels because the nexus's amoled screen actually has lower resolution compared to the LCD version, AMOLED has a pentile pixel layout, which means it has half the red and blue pixels compared to the lcd one.

You are correct that the difference is due to AMOLED vs LCD, but the resolution is the same on each, 800x480.

Each "pixel" on the Nexus S screen has 2 subpixels: one green and one red or blue. The pattern goes Green Blue Green Red Green Blue Green Red etc
Each "pixel" on an LCD screen has 3 subpixels: one green, one red, one blue. The pattern goes Green Blue Red Green Blue Red etc.

Got it. But, the resolution is still 800x480 on each device. Each device displays 384,000 pixels at a time regardless of "sub-pixel" structure, right?

In addition,
The human eye is most sensitive to green, especially for high resolution luminance information. Thus the RG-BG scheme [AMOLED] creates a color display with one third fewer subpixels than a traditional RGB-RGB scheme [LCD] but with the same perceived display resolution.

Each pixel on an LCD can display any color.
Each pixel on an AMOLED screen can display either any combination of green\red OR any combination of green\blue.
It's a subtle difference, but it is a difference and it's why the Nexus S screen can look a little weird when you look closely, particularly at complex color patterns, especially when talking grays. On an AMOLED screen, an individual pixel can't be gray.

I definitely notice. My opinion is the vivid colors and amazing contrast make the trade off totally worth it and I prefer the AMOLED.
I was only being "nit-picky" because you used the term resolution. Regardless I learned something here today, so thanks!

Fix uneven/yellow screen with intentional burn-in

So I was on my 2nd Nexus 6P and like the first it had an uneven screen. Normal/slightly pink at the top and at the bottom it's more yellow. Instead of returning it I've decided to try and fix the yellow tint by intentionally causing a burn-in on the over-enthusiastic green pixels in the bottom half of my screen.
To do this I flashed a kernel which unlocks the high-brightness mode of the display, the awesome EX kernel, set my screen timeout to 15 minutes and left the display turned on for 3x15 minutes in high brightness mode with a black-to-green gradient open full screen in the Photos app (absolutely nothing else on screen). After each of the 15 minutes I checked the progress, after the 3rd time I considered it done. I'm happy to report that this has nearly eliminated my uneven screen problem.
So far I've seen no ill effects, just a nice even screen.
I used this black-to-green gradient that was a close match to where my screen was yellow. My first 6P had a different pattern of yellowness, so that would have required a different gradient, more like black-green-black.

Interesting, the normal slightly pink at the top transitioning to yellow at the bottom describes the screen on my original nexus 6P and it's replacement.
I'll look into giving this a try as well.

I´m not sure if something like this could be considered as a defect. If you look at a very high angle, you might see some sort of "rainbow effect" on the screen. You should be careful about "burning in" Pixels in a Amoled screen. High brightness will wear out the LEDs faster than you think. At least this is how I remember my old Samsung Galaxy S3 but maybe Amoled technology has improved a lot.

I can't really comment on if the OP's method is safe or not, but it is worth noting that the gradient/tint change is noticeable even when viewed straight on under normal use, such as browsing etc.
It could sort of be likened to the old TN based flat screens from a number of years ago where the top and bottom looked slightly different colours, however a lot of this was down to narrow viewing angles. I'm wondering if the same applies to the specific AMOLED display used by the 6P as well.
The AMOLED screens on my Moto X 2nd Gen and Moto X Force don't have the same problem.

I have a slight purple tint too on the screen but it is only visible on a white background. It does not bother me, if you set a higher brightness it is barely visible. Maybe all Nexus 6P have this sort of display and you simply have to live with it.

Would you happen to have a before image for your screen? I would like to try this on my phone but can't say for sure what exact color the uneven section is. Most of the screen seems to have a pink tint that fades into a green/yellow tint in the bottom left corner. I don't want to stress the wrong color accidentally.

Can you post before and after pics of your screen please?

Its a well known characteristic of samsung AMOLED screens. Samsung users have been complaining about this for some time. Its actually worse on the sgs6. But more brightness will make it less noticeable. Honestly, if you forget about it and stop focusing on it, you will stop noticing it.

Yeah I understand some are really bad you should send it back.but if its slight. There's no.point obsessing about it. It takes the joy away from using the phone

It's impossible not obsessing about it since the display is very thing you look at when using a phone, people wouldnt tolerate if it was an LCD, dead pixels or any other defect at the advertised price, but since it's amoled we should be expected that these errors occur.
The issue on slight displays is that the screen is uneven on white, so its impossible to ignore on web browsing and how dark ui and gapps is not provided by Google, I would prefer it to be slightly pink/blue all over not half so you won't notice it.
Not meaning to rant and whine but consumers shouldn't have to accept this or fix the issue themselves, when I show the phone of friends, they notice the inconsistent white background and are shocked when I say its something you have to live with, the features are not going to outweigh the display issue
The joy of the phone is still there, just wish they implement quality control.

I complained about this on my Nexus 6. Ended up buying and returning a total of about 8 phones from various stores until i found the "perfect" one. Its incredibly irritating when you can notice it and its the first thing you see when the pixels light up. Some people may care more than others but im not willing to compromise anymore. AMOLED displays look great, but LCDs seem to have a better yield or QA. I was of course down voted and flamed about this. Good to see people starting to take action against garbage quality AMOLEDs.

This post is old but I wanted to try this nonetheless. You can't just burn in or wear out the pixels in such sort of time no matter what. 45 mis is not enough to cause such an effect. I tried it as I have a screen with the same exactly issue but there is no change. And I did it for far more than you. I let it all the night long for 3 days. There was no change. I don't think you can fix this issue this way (or any other way)

You guys keep saying "AMOLED issue". I bought 6p after having OnePlus X - it has AMOLED without any issue, it was perfect screen! Nexus 6p is great phone, but screen really bothers me... I hate, but I need to replace the phone. And I am not sure whether I will get a good phone or not. Support told me that if I would ask for replacement - they could send me a refurbished phone. Only buying new will give a new phone. I can still return it as I have it for few days...

Hey,
Seriously, a refurbished device just after a few days? Like you had it for 10 months, lol? Is it Huawei?
Escalate the case to a supervisor and don't give up until you get a "proper" new phone!
Good luck...

Screen burn already?

Last night I noticed that my soft keys and notification bar have already started to burn into my phone. I was planning on keeping this phone for years. Is this happening to anyone else? Should I try to get a replacement? It is still a pretty brand new phone.

This is pretty normal, actually. The biggest disadvantage with AMOLED-screen phones is that the screens degenerate before you get rid of the phone. My Turbo 2 started getting screen burn-in about 5 months after I purchased it, but I exchanged that one for a new one. The On-screen buttons on an AMOLED display only makes the problem worse; AMOLED-screen phones with capacitive keys will only get burn in at the status bar, in typical conditions. Another thing: since the AMOLED screen is primarily made of a multitude of LEDs, these LEDs are driven very hard when white is displayed on the screen, and the LEDs turn themselves off when black is displayed on the screen, so that contrast between the black bar and the white buttons causes the bar to "reverse burn", where the bar will show colors the way the entire screen did when the phone was new, the other parts of the screen will be darker and dingier than the bar (and the status bar), and the on-screen buttons will be the dingiest part of the screen. Also, by "dingy", I mean the AMOLED, over time, will take a noticeable shift to yellow, where every color will have a yellowish cast, due to the Organic Decomposition of AMOLED screens (they are made of organic material) as well as the fact that the blue subpixels are the first to decompose, because they shine the brightest. The yellow shift over time cannot be changed or reversed. The on-screen keys and bar burn in can be slowed/ counteracted by downloading an app called GMD Immersive, which allows you to put your phone in Fullscreen mode in most situations you are using it. You do have to bring up the on-screen keys when you are using the keyboard, but in most other cases when the screen will be on for extended periods of time, the on-screen keys and black bar will not burn in as quicky and this app is a good thing to use to counteract this. However, the GMD Immersive app also allows you to take the status bar out of view, as well. This is a very good app for any AMOLED-screen phone to counteract the eventual burn-in that you will receive. *Side note* I know this is unrelated to what I just said, but the belief that AMOLED screens are more efficient than LCDs is not always true. It largely depends on the content you put on the screen. An AMOLED screen will be more efficient than the LCD when colors displayed on the screen are darker/closer to black, where the AMOLED's LEDs are not driven as hard or are not turned on at all, whereas the LCD's backlight is still active when displaying dark colors/blacks (It is a good idea to surf the web in invert cors on an AMOLED-screen phone if you want to save a lot of power). An LCD display is more efficient displaying lighter colors/whites, because the AMOLED's LEDs are driven very hard when displaying whites/lighter colors, and are shining brighter and using more power to do so, whereas the LCD's backlight is working no harder to display whites than it is to display darker colors. For my usage, LCDs would be more efficient than AMOLEDs due to the fact that most content I display on-screen is usually white or a lighter color.

Last night I noticed that my soft keys and notification bar have already started to burn into my phone. I was planning on keeping this phone for years. Is this happening to anyone else? Should I try to get a replacement? It is still a pretty brand new phone.

It's usually not permanent, it's more image retention than burn-in. If you're worried about it, just run this program, or one like it regularly-

CRT's and Plasma screens, however, are very prone to burn-in, especially Plasma. Screen Savers help on CRT's, and most newer Plasma displays have tools built-in to help keep the screen free of that. LCD and OLED screens are much less prone to burn-in, it can happen, it's just pretty rare.

It is permanent, and running that app for hours and a bit each day didn't fix it. After using another phone for a few minutes, I noticed just how yellow the screen on my Z Force had become in just a month. I'm so sad. I really wanted to love this phone but now I just see yellow sadness.

I haven't had any screen burn since my Galaxy S4. And i just checked my Z and nothing. I have about 5 hours of OST a day and have been using this since launch.

I sure hope not. Still trying that app. Verizon offered to replace it, but I don't know if it'll just keep happening.

What I would do is simply get a replacement Z force, and when u do get your replacement, I would use an app called GMD Immersive (look it up on the play store), which will allow you to slide your on-screen keys in and out of view, and/or your status bar as well. My turbo 2 got burn in after 3 months of using it, but ever since I started using GMD Immersive on my replacement Turbo 2 (the other had battery issues) I have little to no burn in even after 2 1/2 months of use.

I know this sounds silly but are you sure you don't have some shift enabled that makes the color temp plummet in the evening?
Since Apple came out with night shift there are people taking their phones in because they are yellow at night! LOL

Really hope mine dosnt get screen burn. Im using the gmd app as suggested but I find the keyboard gets buggy. My Moto XF also got burns after few months. Really hope this isn't the case for this beauty of a phone.

Waiting on a warranty replacement from Moto. Had to take pictures showing the burned in images and email them. Going to try the app from day one and hope for the best.

Yup just noticed mine has a highly visible burn. That's just crazy. My 3 year old nexus 6 has no burn at all. I would request a warranty but I do not want a refurbished phone.

Could the yellow be from the plastic upper screen protector?

This is pretty normal, actually. The biggest disadvantage with AMOLED-screen phones is that the screens degenerate before you get rid of the phone. My Turbo 2 started getting screen burn-in about 5 months after I purchased it, but I exchanged that one for a new one.

I have/had burn issues with my Moto G4 (IPS LCD Display). The problem is in the pure whites on screen, those are the objects which burn in. Since pure Android Marshmallow or Nougat don't provide a different colour tone setting, I worked around it by downloading a Bluelight Filter app (I recommend Hardy-Infinity's filter). I select the neutral black filter and put the intensity to 11%. that resolves all the burn ins, while used.
It's quite an annoying problem, and the only reason why I refrain from buying anymore pure Android phones, until the OS comes with an integrated screen tone setting.

This "issue" is totally normal with an OLED display, and there's really nothing that can be done to stop it, or "correct" it, other than not use the display!
The menu bar will be the most noticeable artifact in the early going, but with years of use you'll see the entire screen, with the exception of the typically-black menu-bar area(!), will no longer be as bright. The whites will be more grayish and the colours will be more muted.
All-in-all, you'll probably never really notice or care about it, but that said, no magical app is going to restore what is a natural, unavoidable, process for these screens.

Well, a relative of mine got the Z Force for Christmas last year, and the screen had severe burn in and the shattershield was fuzzy from discoloration and hairline scratches. The burn in was so severe that the navigation bar, the notification bar and home screen icons were all visible on solid backgrounds. Fortunately, Verizon replaced it under warranty. I've loved Motorola since the StarTac days and have recommended them to everyone, but seeing the burn in issues on the Z and the lack of innovation in the Z2 Force, I can't recommend them anymore.

That late reply you weren't expecting..

Yes, the screen burn issue is real, very real. Among other user + upside down port-a-potty issues constantly popping up.
I had experimental high contrast text on for minimal time but think it likely had more to do with me leaving vibrant colors mode set on for a couple months before I noticed the burn-in of Google emblem and notification bar.. yep, the same notification bar that always is wasting scarce screen space instead of scrolling up and away like on every decent phone on the market.
I enjoyed my Droid X as a more user friendly and functional device than the MOTO Z, which has been an ongoing hate-hate dysfunctional relationship.
