Does anyone experience a "white shadow" problem on n1's screen?
when i read a document, i notice the margin area is not purely white, but there's "shadow" of text on the right
is this a amoled limitation of is it just me?
I will try to take photo if the explanation is not clear enough
another issue is that i've always found the n1's screen color to have a red hue
same for this, is it just me or do you have similar experiences?
Hey, no red hue but i do sometimes have a 'white shadow effect' which i notice looking at text, such as reading an email [not 100% sure if this is same problem as yours tho].
i was worried that this might be a problem with the screen but its just a fingerprint issue - all you need to do is wipe the screen!!
the finger prints left on the screen were what caused my white shadow, wipe the screen clean and all the text is evenly black.

I have also seen this phenomenon, specifically in the web browser when there is a white background with back text. It doesn't happen all the time, but its fairly visable when it does. Perhaps this is a defective amoled screen issue? Or maybe just amoled screen artifacts.... not sure. Anyone else seen this?
Also this isn't a fingerprint issue, happens on perfectly clean screen.
I have the odd ghost shadows when reading black text on a white background too.

I see this too. I just chalked it up to a byproduct of AMOLED screens or something. Doesn't really bother me and I don't really notice it that much either.

hmm that's strange because i do sometimes have exactly the same problem and can see the problem disappear as i wipe the screen. From my limited knowledge about amoled screens it seems unlikely that the pixels could be experiencing some sort of 'come and go' problem such as this. If someone could put up a picture...
Well for the record this is a very minor issue, I like my N1 a lot, its hardly noticeable. However I am interested in investigating it, and attempting to take pictures of the effect was well, less then fruitful.
It turns out my digital camera doesn't take pictures up close that well, its actually pretty terrible. I was trying to get a screen shot app to try to capture it but the ones on the market are only for root users, and I haven't made the plunge into root, yet.

I have this problem and it's very off-putting.
Does anyone know if it's theoretically possible to calibrate the screen à la a computer monitor to reduce this reddish casting? In greyscale photos all shades have a very noticeable pink tone (not photos taken by the phone's camera).
I'm giving this thread a kick, because I also experience this 'problem' of having (faint but clearly visible) ghost lines or 'white shadow' when viewing small text/objects (Nexus One), especially noticeable in the browser. The weird thing is, it completely disappears when switching to landscape mode. Turning the brightness down worsens the phenomenon.
It is also reported at Google's Android support, sadly I can't report the link because of my newbie restrictions I also found one report of the Desire having this problem.
I would ask felow Nexus owners if they want to turn down their brightness and report if they also see this ghosting in portrait view (i.e. when viewing an article on nytimes.com fully zoomed out), so we can conclude if this is an insoluble AMOLED related issue or an actual screen defect of your phone (RMA/waranty-issue).
I have the text ghost image on white background. I thought it was software issue, but since it disappears in landscape view that might mean its a limitation of the pentile sub pixel layout.
I think this should explain it. It's not really the AMOLED, but how the "pixels" are actually laid out.
arstechnica.com/gadgets/news/2010/03/secrets-of-the-nexus-ones-screen-science-color-and-hacks.ars
I read that this issue doesn't occur in the old Dolphin browser. I don't have my phone with me right now. Can someone try it? I doubt it has anything to do with the pentile subpixel arrangement. I mean if the part of the screen is supposed to be white, the pixel should display white, not grey. Probably a software issue, IMO.
I just checked, shadows on both. It's a screen thing.
My bad. You weren't using the Dolphin HD browser, were you?
Thank for your replies I don't think it is the browser though, the same problem persists in Gmail, Adobe PDF Reader and Documents togo, I suggest you use one of these applications to look at small text on low brightness. It might be a little more noticeable in de browser, but looks like it isn't a pure software issue. Can you confirm this finding?
@voiceunebunu: yes, I've read that, but that article concentrates on text fuzziness etc. because of the PenTile arrangement, but does not mention this 'ghosting-like' effect.
Of course this isn't such a 'big deal': I would rather have my screen calibrated so it doesn't show up al reddish and get a better screen view in daylight, but hey, I knew about those problems before I bought the Nexus, but this one seams to be very sparsely documented on the internet.
This effect reminds me of the first, monochrome LCD-displays, which also had this problem (only 100x times worse), especially if they grew older.
Possible work around?
Hi everyone,
I've found a work around for this!
Cyanogen 6 has a feature called "Render effect" and basically, there are options to change what and how colours are displayed.
The last three "calibrated" seem to be for the Nexus specifically. I've used all three and the "calibrated" and "calibrated (cool)" are my favourite. Both slightly change the colour output.
There is a slight yellow tint over whites. For my screen the ghost lines are greatly reduced (it used to be visible with normal size text and exceptionally bad when zoomed out). Now its only slightly visible when zoomed out!
Hope that helps!
Hi all,
Got the Galaxy S for a month, pretty happy with it. Yesterday, the brightness suddenly gone up. The worst part is the display lost the gradient scaling and it is replaced by colour bands!
Apps like the stock video player for example. Before the video is played, you can see the grey control bar at the bottom covers by a lot of colour bands. The colour of the movie is all washed out as if you were playing it in 8 bit colour mode. Where the same avi played okay before, crystal clear and colour was rich.
Same thing with the charging screen while the phone is off. You can see the colour bands on the grey area of the shadow of the green battery. Just wondering if anyone has the same problem?
Cheers!
Factory reset :d
Tried all that full factory wipe, data reset, flash to different rom. Nothing works
Then your device's probably faulty. replace it.
Pretty certain it is. I took a screenshot of the video player and it looks fine but on the screen, you can still see those colour bands meters away.
I guess this indicates the LCD is faulty.

The galaxy s has no LCD its LED
Ive noticed when you slide down that tray from the top, when closing it mine has MANY TIMES switched to full brightness. But simply tapping the brightness button on the multi widget thingy makes it go back to how I want.

Thats because you can adjust the brightness by sliding your finger accross the notification bar.... doesnt work if you have auto brightness ticked...

Hi I have the exact same problem! But I didn't notice it before now wen I saw this thread. But all the colours are just fine when I play a vid, it's just the grey controlbar that is by many stripes of different colours, looks like 8bit colour. But when the vid starts playing its just fine, because it gets transparent. Should I get this phone changed, have just had it a couple of weeks.

Hi Radat,
I posted more info in the other forum including some screenshots. http://forums.whirlpool.net.au/forum-replies.cfm?t=1520586
Hope yours okay. I am going to call Samsung tomorrow.
romhunter,
yup, saw the screenshots, looks like quantization problem i.e. that colours are using fewer bits than normal. For example, RGB screen might use 24 bits per pixel, 8 bits per r/g/b colour, the screenshots seem to suggest only 5 or 6 bits per colour.
Hopefully this is just a software glitch, though you said you already tried factory reset / wipe, could it be a loose cable wire somewhere or maybe a problem with the screen to mainboard connector?

On my sgs, there is a green colour attached to to the grey colours, I can see it really good when using Screen test app on the gray scale screen, all grey is sort of green!

Just got a brand new device. Used it for about an hour, then the exact same thing happened - out of the blue.
Any possible home-front solutions? Having to take it to be serviced is a PITA for me ATM.
Mine definitely seems to have banding in the video player control pane before the video playback starts. Can someone please post a screenshot of how it should be? I haven't seen the banding issue anywhere else except the battery charging indicator when charging the phone when it's turned off. And as far as I remember they were always like that.
So can someone please post a screenshot of how it should be for me to compare.
I have the same problem appeared after upgrading to Froyo. Brightness increased (even it is high in the lowest setting) and color saturation also increased. As a result, i see bandings or lines where a color gradient exist. I added an example photo from "Samsung Apps" page. You can easily see bandings on the bottom. I see such things in a PC screen if color adjustment is not optimum. So there must be a way to adjust screen saturation and brightness by a software through registry i think. It seems like a software problem. I think it is a very rare problem, i found few people on the web complaining about it. Mostly HTC Desire, which use also Samsung Amoled screen, users complaining about it.
I did everything said on forums to solve it but no way. I flashed many different roms both eclair and froyo, use a software given in HTC forums to change RGB color, changed color settings through video player etc. Nothing worked. Please help

I looked at ur pic. I honestly dont see any problem with it. What is this banding ur talking about?
Sent from my GT-I9000 using XDA App
Bottom of the screen, around "2010 Samsungs Electronics". This part should be a smooth color transition from blue to transparent but there are circular lines between colors. Is your screen the same.
Another example. The one on the phone looks white on the upper part where a color transition from dark to light black exist and there are visible lines. But normally it was looking like the other picture (taken from notebook screen) before this problem
ah on that screen i already see 8 shades of blue, most be around 4k colors .. bummer though, it's normally a software problem, doubt that a conector has come loose. (but possible if it's a pimped up composite plug with Y/Pr/Pb, .. eh still impossible cos it's getting decoded before that)
Hi, I love my Xperia T but there is one thing that bothers me. I noticed that every xperia T has that automatic screen dimming when viewing darker media on your screen. For example, when i turn on facebook app, before the actual app opens there is dark grey screen. During that sequence screen gets darker, and when white facebook page pops up you can actually see screen adjusting its brightness to higher "normal" level. That really bothers me especially when gaming. On dark sequences screen gets really dark, and than it takes second or two to adjust normal brightness when brighter sequences appear. You can actually see brightness going down when darker images are displayed, and then back up again when brighter images appear.
So I'm not talking about dimming when overheating or flickering (that second is fixed by jellybean update as I noticed), or etc. And before you ask me I if turned on autobrightness in display settings, it has nothing to do with that.
My question is, is there a way to turn this off because it is really annoying?

All i thought it differs to auto brightness thats why i ask it sir. Sorry for the question then
You dont have to apologise. So, the problem is that when you watch darker images, or videos, or just any darker screen on your display, contrast and brightness goes down. And when you switch to brighter screen you can actually see, with your naked eye, brightnes going up. I see that Sony intentionally put that feature, but it is very, very stupid one. There is no point in making dark images even darker with even less contrast. I assume they wanted to achieve better black levels that way, or I don't know, but it is very stupid way of doing black levels more black. And, of course, there is no setting in settings menu tu turn this nonsense off, nice one Sony!

This similar annoying ass feature is there in my Spectre laptop. This was supposed to be a battery saving feature and I haven't yet found a way to turn it off. Maybe it's also a way to get higher black levels.
This is the Bravia Engine. Just unselect Settings -> Display -> Mobile Bravia Engine

Dude, this is definitely not a battery saving mode. There is no need for batery saving mode when displaying dark screen, and the problem occurs when displaying dark images or any other dark media, app or non-app. every single time.

OMG... Mobile bravia engine has apsolutely nothing to do with with that, because bravia engine works only in phones stock apps for viewing videos and pictures, and the effect is not even similiar to screen dimming. It brings more saturated colors and that is all.
Same problem is posted here: http://communities.sonyericsson.com/thread/61560?start=0&tstart=0 and Sony replied "I'm sorry that it has taken so long but I have done some testing now using a later software and I'm not able to replicate the issue that you guys report so I assume it's fixed." It is more than obvious that they like to close their eyes on every single problem that occurs. Thank you Sony for your gorgeous support to your beloved customers. I cant be more sarcastic, of course.

It's not my way, it's the way it is. If one understands what mobile bravia engine is, one could never offered it as a solution to a problem that has nothing to do with it. I'm terribly sorry if I ofended you, and I apologize for my attitude. I'm not mad at you, or anybody else here, I just don't see why would one write something just to be written. I know my T-Rex wery well, and I know there is no "normal" way to turn this dimming crap off, so I posted my question here, and expected that someone of the experts would offer some kind of solution to that. And I got things like "turn automatic brightness off", or "turn mobile bravia engine off" even though I previously mentioned that i tried all that stuff. People are "trying" to "help" me here, and they didn't even read what I've written. I'm really not one of guys that would post a question here just to be posted, I searched the crap out of the internet, and I found apsolutely nothing helpfull. That's why I decided to open this thread, to hear what experts have to say.

Thank you guys very much! Changed values, and rebooting my phone...everything is fine now, no more stupid dimming. However...I noticed that color adjusment is still visible when changing from dark screen to colorfull bright one. So the dimming is now definitely gone, but that color adjusment is still visible, like it changes contrast a bit, from worse to better, it is clearly visible. Any ideas about that?
I'm uploading a video I recorded with my webcam to get you a closer look. I'll post a link once it's uploaded.
Video will be live here in a couple of minutes: http://youtu.be/fHozO8zGZ1Y
After I managed to turn off DLS, that auto-contrast thing still remains. If you look closely, you'll se that the blue facebook stripe (and everything else) slightly changes its color/contrast when returning from the gray screen. But DLS was much bigger pain in the ass and I'm very pleased with the result od turning it off.

I think we have the same issue. Check my thread here. I saw a video in youtube that's exactly what my phone is doing, if you have the same issue then I wouldn't exchange it, that's what I did.
I stated to notice lines going down my screen when closing some pages and apps.
I loaded some blue sky and grey images to check for sure if I had the same problem your describing
and it looks like I do
I have about 10 vertical lines that's very faint and a bigger line right down the center of my screen
the link above looks like a different screen problem than mine
Not sure what to do as 99% of the time you can't see the lines but now I know about them im thinking what if they get worse over time
It's very hard to take a picture of them also
Love this phone. But damn screen is already burned-in. Can see ghosting of the nav bar and clock. I'm sure a lot of us do.
Has anyone been able to fix it? I tried all those apps. Blinking colors, all whip_te, inverted. Nothing works for me.
Is there really a fix for ghosting on the amoled screen?
