oled screen issue?

can you guys try this out and tell me if you see this on your screens. first turn down the brightness and go to a web page with lots off black text. on my screen everything black leaves a faint line across the screen wherever there is a black pixel from right to left. do you guys see this? out is much less noticeable when the brightness is turned up.

I've seen a tiny hint of this in my screen, but it hasn't bothered me. If it's severe in your phone, you may want to contact HTC.

yes I notice this as well but I have to say that is only noticeable with backlight set to minimum, and i think it's a normal behaviour of an amoled screen. Now I have one question about the screen too:
When I'm watching pics or movies the screen has a very good resolution. For all the rest the screen seems a bit dotted and grainy, especially with text. For example in the app launcher where the app's names are written in white and the background is black the text is not extremely clear and if I take a closer look theres seems to be pink pixelss on the letter's edges. I can notice this thing almost evrywhere but I think it's a lot more clear to see with text and the backlight set to max. do you manage to see this too or do you think that's because i have a defective phone?

the grainyness on thin objects like text is 100% normal, its just how these OLED displays work.

This guy did some awesome research into the graininess issue using a macro lens on his camera. Really interesting stuff...

Eheh it's me that started that thread and i think that guy really did a great job trying to explain what's the problem... now i'm curious to know how many people notices this because till now it seemed that only me and that guy could see this "issue" so sometimes i'm still worried i have a faulty phone...it won't be a good thing since I'm from italy and getting a replacement phone wouldn't be very easy

My screen also appears reddish when i turn off the blacklighting in the clock app :\ maybe its defective?

No, mine experiences the same thing. Seems like reds are more biased when less power is given to the LEDs (not exactly a "backlight"). This is slightly noticeable on the lowest brightness setting too.
And mine experiences the "black line" issue too. I guess it's just how OLED screens work.

ok thanks, it's just reassuring to know that its not only my n1 experiencing this

Seen it slightly a few times. But never bothered me since I'm never in very low brightness that much.

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 .
Sent from my Nexus One using XDA App

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

Weird screen issue, confirmed on two so far.

I don't know if these if happening on all our s2's.
basically, I noticed brightness goes down when displaying a lot of whites. e.g. google vs the whites in a page with more darker areas. (i don't think it's my eyes.)
I've never noticed this on my hd2, or any other phones.
when displaying google's in the browser, the white is not impressive at all.
another test i did was with an image I created (attached), half black half white. open in gallery and slide it so more black shows, or more white shows. The whole screen changes brightness!
My friend's S2 does the same.
can anyone confirm?

That's actually a power-saving feature you can turn off.
Go into Settings -> Display -> Scroll down and untick 'Auto adjust screen power'.

Its not.
Its definitely there irrespective of display settings.
Basically even when you are not moving picture, have a look near the border.
There is definite grey banding near the border. It kinda looks like white is bleeding into the black.
And its there on every SGS2, every single one. It can be hardware or software issue.
@OP. you are definitely not alone. I was actually having talk with my friends in UK. 6 of us now have SGS2. 2 are from O2, 3 from P4U and 1 from Handtec and mine is from Clove.
All are experiencing same thing. Its definitely not your eyes.
@others. Its not a glaring issue. You wont notice i t unless there is extreme contrast images on screen like this one. My dad still couldnt notice it when I was showing it to him. But its still there. Will upload video, but its hard to pick on video as well.

It's an option in the Display settings - auto adjust screen brightness after analysing image or something similar.
Samsung thing, I think, since my Omnia 7 with Windows Phone did exactly the same thing. It's trying to save you power and completely normal.

Thanks very much guys, I think I can accept it if it's all built like that. With that option off it really helped! (I feel a lil retarded now). But for some reason that test image I made still has that dimming effect (double tap it in the gallery, this instant change makes it obvious), but maybe that's normal, not fussed. (normal web browsing is perfect)
And no I didn't exchange any phones. Mine does have a dead pixel tho. Can anyone check their screens for dead pixels for me? I know someone had blue lines and stuff on their units, that's a bit drastic. I'm just wondering how many actually have say 1 dead pixel, so I have a better picture before I actually exchange mine or something.

asefsef said:
Yea, I've already got that turned off including power saving mode (mentioned in first post).

Nah, no dead pixels or other screen issues here. If you have dead pixel, i would return it.
Here is the video, its not clear as camera limitations dont really show it properly, but at 720P you can see it for fraction of second, that is not the lens glare but screen turning grey right above the white border.
http://www.youtube.com/watch?v=zGr7xJ1JIjU
around 0:15-0-18 in that video.

As mentioned, its a power saving feature as AMOLED screens don't like whites as they drain power, they prefer blacks. So reducing the brightness helps to save battery.

I can see it grey in the video, almost like that gingerbread scroll limit effect. very hard to see in the video though, would have just said it was the camera.
Yea I'm considering returning. In my other post, I mentioned how Handtec got back to me. In short, not fault since only 1 pixel, but told me I can exchange/return within 7 days. But, they said since it's not a fault, I'll have to pay shipping both ways. (£28 per way, ouch)
Does that sound right??

Just a thought, could not the grey area when moving a black/white border area simply be the screen pixels taking a few milliseconds to go from completely dim, to grey, then to completely white, ie just a response time, albeit a bit slower than what I would have guessed?
On my SGS, going into a completely black app drawer with bright icons and moving around, it also has a very slight dragging effect on some white/black constrasting areas?

Display problem/yellowish left side

Just got my new SGS2 3 days ago, really liking it but stumbled into a screen problem and would like to know if it's just me/it's normal/I need to change a setting to fix the problem.
Just like the title says, the left side (about 1/3) of my screen changes the colour of the image to a more yellowish tint. This seems to happen just when the brightness is quite low, and tends to disappear when close to 100%.
It is rather subtle, but can be seen where there's white text on a darker background (white characters become darker the closer they are to the left border), or when looking at an uniform colour.
I created this test page to make the problem more apparent: http://fiddle.jshell.net/qFxsC/1/show/
When visiting it on the S2 browser and setting browser brightness to around 20%, it becomes quite visible.
Anybody else with the same problem?
EDIT:
We still DO NOT have pictures of a phone WITHOUT the problem described above!
If you believe your SGS2 has a perfect screen, please post pics of the notification area taken in the dark at both 0-20% brightness and 100% brightness!
UPDATE
Various websites have started to talk about this problem, linking to this thread:

I have just sent an email to GSMarena asking if they could check the unit they reviewed to see if it has the same problem. Of all the phone reviews I have seen, theirs seems to be the most focused on image quality, I'm sure that if their unit doesn't have this problem, they would be able to take clear shots of a flawless screen.
EDIT:
GSMarena took screens of their unit using the above test link, and while so far I believe theirs is the best looking display that we have seen so far, it *STILL* has the problem.
I am going to link this thread to samsung UK next, in the hopes they will give an official answer acknowledging the problem.
EDIT:
latest firmwares seem to fix this problem or at least make it much less noticeable.

Take it straight back and swap it. Seems to be a growing amount of people on here, including myself, with various dodgy screen issues.

The screen doesn't look perfect if you look at a uniform color on the whole screen + low brightness, but... well I don't tend to use it much for that. Could be a limitation in OLED production-technology getting all the pixels to have exactly the same brightness/color etc.
edit:
To answer directly to the question here, no I don't have a yellowish left side. It's just not completely uniform across the whole screen.

I've got this same thing. I first noticed it when using Estrongs file explorer. I always have my screen turned down to 0% to save battery, but didn't notice this anywhere else yet (at least I didn't think about it).
Your posted image does show it clear.
What to do? Could you others comment whether you've seen this? Go to the OP's posted link and set your brightness down to 0%.

I tried to mess around with settings such as auto adjust screen power etc, but the only thing that seems to fix it is crank up the brightness.
We obviously can't keep it anywhere close to 100% tho, this phone sucks battery down quickly already at 0%!
Another thing you can do to check if you have this screen problem is call *#*#0*#*#*
This will make the phone go in the diagnostic program, and if you try the white diagnostic, you can somewhat see the problem, although not quite as clearly as in the test web page I posted above.
I'm considering to return the phone, as it doesn't seem to be getting better, despite having read that some screen problems might go away after a few days.

Mine is exactly the same. It's noticeable at the lowest brightness setting, however if I increase the brightness even slightly it pretty much disappears for general use. It's still there but not really enough to bother me.
On the OP's link I changed the brightness through several settings and at certain brightness levels the whole screen gets a yellow tint. Not necessarily related to the left side of the screen having a yellow tint, apart from I guess a lack of brightness of the blue subpixels relative to the red and green.
I'm not sure if I'm imagining it but I think it has improved slightly on mine over the past week. However if it gets any worse I think a warranty claim will be in order.

Hhrrmm, I'm in a catch-22 here. There's generally a grace period for any manufacturing errors like this where you can quickly get a replacement just by returning it to the vendor. Problem is, my vendor won't be getting any new units in for another two weeks.

I don't see it clearly on the link he posted.
But i do see it in the notification screen. The grey area is slightly darker/yellow tint on the left site. Even when i put it on maximum brightness you could see it. Especially when you first concentrate your eyes on the right side for 5 seconds and than on the left side.
I do seem to notice it on the notification grey slider where your finger is on when you pull it down, on the left side the grey is a little bit "darker" than on the right side of mt finger.
I tend to think I can also see it on the keyboard, whereas the Q has different grey than P on the opposite of the screen...
Anybody could check this out on their phone??
Thanks in advance!

As time goes by, it feels like my problem is getting worse, although it may only be due to me being aware of it.
Also began noticing it in the pull-down message field. Now I see it against white backgrounds as well, almost like a faint green-grey shadow.
I've contacted my vendor and requested an RMA and replacement. They're sending me a shipping slip to send it to them "for control" then they'll contact me on my options from there. Can only hope they see it as clearly as I do and that they send me a new phone as a replacement rather than repair/refurb crap.
Think this is the last time I buy electronics online. I saved 20% off retail on this one, but having the option to do a walk-in replacement at a brick-n-mortar store would have been worth the higher price. <sigh>

I've got the same thing aswell, a slightly yellow/brown-tinted shade towards the left side of the display. Also visible for example in the market menues, the white areas seem to be very slightly darker towards the left side.
Not sure I am bothered about it enough to return it, doesn't bother me unless I specifically look for it. Also it really is very slight.

If everybody has it, no problem for me.
But if the majority does not have it, I would like to have one without it. Do you think Samsung knows abouth it?
When you have a full grey pictuere or just the notification screen and you go into a perfect dark room. Can you also see, some white vertical en horizontal lines? Looks like hardware where the screen is build on?

Here is a photo I took of my screen with a grey background (see below - click on it to enlarge).
For me, its visibility seems to vary depending on the ambient light, but I'm definitely seeing more effects of it now.
Really hope I'm able to get a good replacement. Am reading quite a bit about this, banding, lines and dead/lit pixels.

so do you think it's a hardware issue, or maybe it will be gone??

The lines you mention are present both on my SGS and my SGS2. It seems to be patterns in the actual OLED pixels, and the patterns and lines are static even when you move pictures. Mostly visible on lower display brightness settings. I've gotten used to them and they don't bother me, and since I have the same thing on two SAMOLED-phones I'd chalk that one up to "just the way it is" aswell. Using anything over 50% brightness has them mostly fade into the display light so only really visible on the lowest brightness settings.

My Samsung focus and Cowon s9 (which I don't even think has a samsung oled screen) have that as well on the lowest brightness, I think its inherent to the tech.

The lines you mention are present both on my SGS and my SGS2. It seems to be patterns in the actual OLED pixels, and the patterns and lines are static even when you move pictures. Mostly visible on lower display brightness settings. I've gotten used to them and they don't bother me, and since I have the same thing on two SAMOLED-phones I'd chalk that one up to "just the way it is" aswell. Using anything over 50% brightness has them mostly fade into the display light so only really visible on the lowest brightness settings.

Ah ok thank you!
On a grey pick with full birghtness I can see them too.
On the post 2 post above yours(quist his post) you can see the lines, but now they are not white, but darker, can you confirm you see them and this is what you mean?
Do you also have the yellowish tint on the left side?

For both the SGS and SGS2, the dark lines are there for my devices aswell. They can seem a bit "grainy", and don't seem like perfectly defined lines, though they generally are always straight horizontal or vertical lines. I also have the Xperia Arc at hand, and if you look at a grey-ish image on either the SGS/SGS2, or the Xperia Arc (LCD), the Arc generally has a very smooth grey image, while the SGS/SGS2 has almost like a fine overlay of subtle lines or grids, generally darker in color than the image displayed, though not clearly defined and not completely symmetrical across the display.
Doesn't seem symmetrical enough to be a grid fo the digitizer layer or smtn like that, but definitely a pattern in the display itself. I still pick an AMOLED screen anytime of the day, the Arc display, while more uniform and "blemish"-free in this regard, still has that LCD backlight bleed-through which for me makes the display alot more tiring for the eyes.
Also my SGS2 has a very subtle tint towards yellow when viewing some of the grey test-images some people have posted. Never noticed it on my SGS1, so either I didn't look well enough, or it might be either hardware-related (something causing the pixels on the left side to perhaps not get the same amount of control voltage/whatever for the pixels, thus causing less blue/more yellowish color), or software. Either way, it is way too subtle for me to care at all, maybe this is even according to spec for the SAMOLED+ and some use will even the pixels out, not sure if anyone has some inside knowledge about the SAMOLED screens.

I am definitely seeing this problem getting worse, now it is getting rather obvious as long as phone is lit by artificial light or in the dark, while sunlight seems to make it really hard to spot, even if not direct.
I've been given advice from samsung call center to bring to phone to the closest assistance point, which I'm going to do tomorrow - hope to be able to report back that it is a known problem and they will change my unit.

I hate to make an iPhone reference here, since I'm *not* a fanboy, but Engadget reported when the IP4 was released that yellow spots and banding were due to glues that had not completely dissolved/disappeared and were part of the bonding process of the screen:
http://www.engadget.com/2010/06/24/iphone-4s-yellow-spot-issue-goes-away-with-a-bit-of-time/
Now - the picture above showing a completely yellow left-side display - that looks 100% abnormal and I'd RUN back to the store to swap it out. I don't think that's glue related.
Download an app from the Market called "Dead Pixel Test" and run it with the white setting to see what it looks like. Is it still yellow?

Have this same issue. Noticed it right away unfortunately. It will always bother me if I deal with it.

yellow screen?

Is this normal or do I have a faulty unit?
Screen looks very yellow compared to my other phones.

What is the other phone? Go to settings -> display -> color mode and set color to normal, that will normalize it a little. It's set on vibrant by default. Regardless of that setting though, the screen on this phone is a "warm" one compared to others. The phone on the left is "cold" and bluish in comparison. Warm screens are a little more yellow/red, cold are blue. If the other phone is AMOLED there's your reason, but even if it's LCD, it's just tuned a bit differently. You should know that the phone on the left isn't producing a perfect white either, just a kind of white you're used to. Personally I prefer a warm screen, I find colder screens harder on my eyes.
TLDR- it's working as intended.

Unless you screwed with some settings no that isn't normal. If my whites were that yellow I'd return it. While an LCD might never be as white or black as an amoled it shouldn't look like 20 year old yellow paper either. WIth LCDs if you lower the brightness the screen will become more colored but nothing like that. You can also go compare it to some phones at the store that have LCD's and get an idea if its out of whack.

I spoke to two different support people at motorola ...one said it was normal for this phone as the screen was optimized for gaming?? .....the other said it was not normal and I should return it.
I tried using the app 'screen adjuster' to boost the blue light and it did indeed make it look white rather than yellow so it seems to be a color temperature setting so I'm still not sure wether changing the phone would make any difference and I can't compare in stores because they don't have them yet.
p.s. the other phone is an LG G2 which is LCD

Mine seems to have a little yellow at low screen brightness but it doesn't seem as bad as in your photo. I probably would not have noticed if not for this thread. Is your screen brightness low? Mine gets more white as the brightness goes up.

If it bothers you you can go through the return process and see if another one is different. My phone looks pretty much the same next to my Galaxy Note n-7000. That's AMOLED, but AMOLED or not, screens can be bluish. For perspective, here's what white looks like for reference. Neither of the phones are producing white. One is bluish, one is yellowish. Do you notice it when you're not comparing phone screens? After a few minutes of looking at the screen, going from app to app or looking at pictures, do white things register as white?

I noticed it had a very warm color temp immediately I turned it on, and then got my other phones to compare ....it does bother me yes ...it's like having a TV with a yellowish screen ....I'm pretty sure it can be fixed with a software update and is not a hardware problem which is why I'm not sure if returning the phone would accomplish anything unless I see some other pures to compare
I just found this thread on another forum:
http://forums.androidcentral.com/mo...to-x-pure-edition-screen-has-yellow-tint.html
and this:
I also noticed that the Moto X screen runs a little warm with regard to color temperature. When browsing the web via Chrome, there’s a noticeable yellow tinge, especially when compared with the iPhone 6 Plus’ screen.

This is mine. I think ambient light may affect it. It looked more yellow when I was in a dark room. This is in a well lit area.

Mine is warmer color from 50% to 0%, Higher values and its very white. Didn't even notice it till I saw this post and well, it can't be unseen lol. I keep my display around 10-20% usually on the low side however at night in bed it doesn't look warm at all.

When you take screenshot of course it comes white lol wth
@op: is normal, that's what you get for paying this little. Low quality screens. Check androidauthority latest review of the phone, his screen is exactly like yours.

yeah, ok so it seems it is quite normal for this phone then, although from the androidcentral forum thread I posted above some screens are more yellow than others and some are actually very white, seems to depend on the batch .....i guess I'll just learn to love it :laugh:
