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.

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?

awesome. theres so many little shortcuts like this ive yet to learn. thanks
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?

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)
Hey,
I'm rocking a tmobile 128gb blue note 9 and it takes takes some nice photos but I as I was playing around in my house after sunset(night) I took a photo of my couch. I have my ceiling light on, and low and behold there was a HUGE yellow tint to the photos. Not like a filter but more like the default white balance and tone were completely off. Used my moms iphone 7, and the photo was more natural in color from the same angle and lighting. Also swapped cameras and tried my note's front camera and the lighting was also normal. When I use the camera in natural light, the colors are fine and pictures beautiful.
https://forums.androidcentral.com/samsung-galaxy-note-4/457879-photos-yellow-help.html
Googled it and found similar issues, tho thats a note 4.... Any ideas how I could fix this? The photo still has a ton of detail..it just seems again the default white balance and tone is way way off resulting in an inaccurate color scheme. I can post photos tonight when the sun goes down if it helps clarify
Thanks for reading guys !
EDIT: uploaded the reference images from a later post to the main post. 1st image is the yellow hue one from the back, the front camera is the second image and you can see the image is..normal.
I'd be interested to see an example, are you sure the White balance isn't just incorrect?

Here are two photos using an apple as reference...notice the one w/ the back camera is much more yellow in hue than the front camera. I wish the back camera was similar in color to the front colors.
Found this article:
https://www.androidauthority.com/samsung-galaxy-note-9-camera-review-900461/
It seems the note 9 actually may be crappy at determing the right white balance/temp with poor light which leads me to think, if this is the case then why does the back struggle while the front is able to do it properly?

I agree, lower lightphotos get pretty yellowish. Seems easily fixable with a patch. I hope it is.

Thank you for the reply.
I googled a review and it seems to be the case with low light, easily fixable with any photo editing software. You want 2500k for indoor photos, which is what I adjusted the white balance to and then wham, perfect.
The front camera doesnt have this issue, but the back does? What gives? It's obviously a software issue...
I was worried I had a defective unit, but it's safe to say it may just be samsung's software?
Yeah after reading your comment, I used Snapseed and TOOLS - White Balance - AW (auto) on my 3 previously posted photos. Before/after comparison:
EDIT: sorry Ⅰ messed up, some of them came as thumbnails and the newer ones as full size images. To compare it is better if you click-open them all on different tabs and switch between the tabs.

Can only see the before photos, maybe use imgur instead or upload to the forum instead?
Yeah well, if my unit isnt defective and this is widespread perhaps maybe we can get a few more people to test it and submit it to samsung?
Maybe nothing happens but hey worth a shot....it really does seem like an easy fix(hopefully)

Fixed. Now that I fixed it btw, I guess Using Snapseed Auto White did not really give the best results. Only improved the lighting a little. I should try the 2500K thing properly..
BTW what app do you use? All apps I tried until now do not let me specify 2500K, but instead, have a + / - % adjustment slider.
Low light performance is bad beside my old p20 pro

Low light performance is actually pretty impressive.
Here's DXO's Note 9 Low light test vs P20 Pro Low light test.
Note 9 takes the win imo.

I took my photo originally in pro mode, with 'save jpeg and raw photos' enabled. I used all auto in pro anyways, so it's the same as auto just also saves in raw...
I then edited my photo in snapseed, which then prompts snapseed to open its raw editor. You aren't given as much to work with as with a jpeg.. but you can adjust the basic settings such as temp, wb, etc.
Anyways, when you're in 'raw mode' in snapseed, it shows you the default temperature(i guess JPEG doesnt save that info?) and you can slide it down to whatever temperature and eyeball it to see what looks good. Every one of my photos taken indoors with a yellowlish light, if i simply edit it...it becomes normal.
Here's a chart actually for WB: https://www.shopmoment.com/momentist/how-to-shoot-manual-white-balance
Now the question is, why is it that indoors my front camera produces auto photos with perfect white balance but when I use my rear camera, it has a messed up white balance when taken in a room with yellowish lights? You obviously have the same issue, so I think we can rule out defects. I noticed the yellowlish tint/white balance being off in some example low light photos at night actually where theres yellow light present in some reviews of the camera on various websites. This seems like a system wide thing, and would be great if maybe some others could test it out so we could make some noise?
Nope ....

Nope what? If you're referring to off wb, it only appears to happen when the main light is yellow. Otherwise, the camera works fine. Went outside last night and took a photo, it's very good in low light. Inside with the lights on(mine are yellowish in hue)? Photos come out wrong.
In your case...seems to be no major yellow light source.
My photo, willhemmens photo with the skulls and the photo here( https://forums.androidcentral.com/s...21378-yellow-hue-photos-help.html#post6389992 ) with the yellow hue. For some reasons, photos under yellow light are producing off balance hues. Any other light? works perfectly....
Least my case, but maybe I have a defect? It's what im trying to figure out, but it seems like others are experiencing the same. Don't wanna go in for a warranty claim if I don't have too.

Hi, I wanted to ask if you guys, have the same effect on your screen. It happens to me only when I'm in low light situations, and it's like, the dark colors, like, mix together with the color that was before in the place that is now the dark color. Only happens when I move any dark/black content on my phone, fast, or not to very fast, but no slow. The best way to see this effect is on dark mode, and on the status bar. Take a reference the white part of your brightness slider. Then, you moove up and down your statusbar, and if you can see it, you'll see like, the dark part of the brightnes slider, shrinks when it's moving (taking as a mark the thickness of the white part of the brightness slider). At first, I thought that this was like a system effect (animation), but then, I saw it on a photo, the same effect, so I think that my screen is defective. I upload a video in slow motion for a better look, and to understand me. Also, I forget to say, but in the video you won't notice it, but, the part that shrinks on the brightness slider, it color, slightly changes to a blueish color.

haven't watched the video, but i think what you're describing is black smearing, it's an amoled thing becuase when black is onscreen pixels turn off

I don't quite understand what do you mean. But for my mi 9 lite, when the screen is all black and only has a few places of lighted up areas, those pixels seems to last a bit longer after it had brightened up.
Idk if that's just what AMOLED does.
This is normal for OLED screens, i have seen same effect on Samsung Galaxy S3 - S9, Nexus and OnePlus phones. Black = off pixels. When they turn from black to something else, they need to turn on. This causes a delay, which leads to the blurry purple affect. It can be slightly annoying but the colors, saturation and contrast outweight the con's IMO, i dont see myself coming back to IPS.
It also happens to me in the Mi 9 Lite. It seems to be some technology used on the screen.
Hi
can you help.
Since upgrading the depth in colour on the camera is very poor.
I sell vacuum cleaners mainly online and used to love how the pictures came out. Now they look very weak in colour with no depth.
I won't lie. When i first got the camera I can't remember if i made any settings changes but I have been playing around with it and can't seem to re-create it.
One thing I used to touch the screen to focus on a point and the picture used to darken slightly which looked good. Also it was a circle. Now it's a square and the picture goes lighter which I hate.
Can you guys help..?
I did try to roll back to EMU 9 through hi suite but it won't give me the option. I did enable HDB etc but it still does not give me the option. If you guys can't help with the camera settings, is there any other way to rollback..? I don't care about security etc and new features, the main use was for the pictures.
Hi,
I was wondering if you saw the option to revert to factory settings in camera when you open settings? Try doing that?
As for darkening the photo, when you touch the place you want to focus, the little sun appears on the side of the square. Try swiping up or down to lighten or darken the photo.
