i9000 screen problem

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?
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)

[Q] Faulty screen?

I have a question about the screen on the SGS, i just got one and when i look closely on the screen I see small dots. Kind of like a chessboard feeling, I noted it first when I looked closely at the "Application" ikon in the bottom right corner. The four white fields look almost like small chessboards except that the "black" squares are more grayish and not black as in a real chessboard .
I'm wondering if my screen is somehow faulty or if it is supposed to look like that?

Try to do a screen test. Type in the phone (*#0*#)

okey, what am I looking for in the screentest, I have done that before, as I recall there are just at series of color test, the pattern im speaking of is on the whole screen, almost as if it was low resolution or something, I saw some information on a thread about this, but I cant find it anymore.

Bring it to a service center/phone shop, compare it to whatever display models they have? If you see a difference, you can turn it in on the spot

That's called the pentile effect. Just google pentile. Its how it is there is nothing you can be about it, although from a normal distace you can't see it. Its most visible on gray i think.

Listen to this guy.
Samsung used a pentile matrix (one pixel now consists of 5 sub pixels - 2 small red, 2 small green and 1 large blue) for some strange reason. I'm only taking a guess here but I figure it has something to do with the way OLED screens degrade. Blue degrades the fastest so I guess it makes sense to have it the largest as it will then have more "say" in the colors that are made. This is the same reason people complain that their screen is blue when it's supposed to be white. It is this same layout that makes the grid pattern and text harder to read than retina displays.

Thank you for the information, I was worried that i had some "resolution" issue. And true enough at normal distance it's no issue. I only noticed it while comparing some stuff to a friends iPhone4.
I have a buddy with a SGS, gonna compare to his "just in case".
I've heard people talk about dithering so I thought I might as well ask, for example while starting the samsung app the blueish background image is indeed dithered on my device, is that normal? Also when playing a video (stock player) the menu where you can scroll consist of lines of gray instead of being smoothly gradient.

i have this gradient issue either. there are steps in color gradient, is this normal??
for example when u look at the grey parts of the battery when ure charging the phone while it's off. or the samsung apps loading screen. and many more...

[Q] Note 3 Screen Banding/Vertical Lines

Anyone else notice/have issues with their Note 3 screen banding vertical lines? is it normal or should I exchange it for a new one?
They are mostly visible with grey tones in background.
Thanks in advance.

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

Light Bleed ?

From what has been doing the rounds, it seems as if the issue is real, but so far nobody has proved that it exists, with side by side comparisons showing different wallpapers or by playing videos.
Passing up on this phone would be quite unfortunate as there really is no true alternative to the Nokia 6.1 Plus, with bootloader unlocked, of course.
It'd be great if anyone could show how exactly the bottom area looks, on loading up different kinds of contents :fingers-crossed:

There is not light bleed. The light bleed that seems like is the navbar gradient on android oreo. I am a moto one power user and I assure you. There is no light bleed even at max brightness!

Some youtubers
Some youtubers done lcd test and we can see screen bleeding issue. On a plain black or grey background screen bleeding issue can be seen.

please, Prove it.

I tried, and i am confused

I got my phone 2 days back and the first thing i noticed was brightness on the bottom part of the phone (bottom part of navbar) was more than rest of the area.
I tried with 3 apps "Quora" "Whatsapp" and "Curiosity".
When i launched Quora, Navbar gradient was observed and it looks like backlight bleeding.
But when i launch Whatsapp or Curiosity, the navbar gradient disappears even at max brightness.
So i think this is not backlight bleeding, but i can't verify this with other apps, or even while watching videos on full screen.
this is definitely confusing. we need more data.

Bleeding
Backlight bleeding only visible on some background Colors. Is there anyone on Xda that can prove it that it is or it is not bleeding

What is there to "prove" ?
Take it from users who use the device daily. And coming to the YouTube reviews, aren't the review devices pre production? How good is the hardware there? The navbar gradient is implemented in a weird way by motorola which makes it feel like the light bleed in most of the apps. But I can assure you that its not there. I have tested extensively and you need to physically see it to understand the difference. You cannot visualise it over photos on the internet.

I mean if you people can remove that gradient and show us

No, what i meant was..... Moto does not give any UI option to user to disable Navbar gradient.
It's either system controlled or app controlled, i am not sure.
And like i said earlier, its not visible in all apps. so does not look like backlight bleeding.

Screen Bleeding Issue Solved.
For those who are wondering about the Screen Bleeding issue with the #MotorolaOnePower Let me clear out this for you, Yes, screen bleeding issue is present and it is ARTIFICIAL. (I don't know why but it is) And can easily be fixed via software updates.
How to disable it?
Install "Navbar Apps" from play store and make the navigation bar colour to solid white/black to overcome those ARTIFICIAL SCREEN BLEEDING issue or wait for the #Android9Pie Which probably will fix this issue.
Hope it helps.

What I think to test it. If this is software based gradient or artificial then screenshot can capture it. If screenshot can't capture that gradient it means it is screen bleeding. Can anyone test it and upload screenshotss?

The gradient is an overlay applied on the screen. It is similiar to the Night Light feature, when you capture screenshots with Night Light on, you don't see it in the screenshot.
Hope that helped clear confusions!

Note 9 yellow photos in low light.

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.

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

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.
