Gradient Banding on my G2 - need help!

A while back I opened my phone to fix a few other things which was actually successful (power button, touch digitizer, in ear speaker volume).
But when I reassembled my phone, I powered it on and I noticed that the colors were dull on my lcd, with noticable banding in gradients that were black grey white. This occurs in everything that appears on my screen including videos; even pictures that I take on the phones camera after they are tranferred onto my mac - still have banding!
So I thought that it must be something to do with the phones lcd screen? And its not able to transition from gradient to gradient in objects, which is causing the banding.
Anyone ever heard of this being a problem? Any solutions? Even ideas that can help me figure out how this whole thing works.
Appreciate it.
The first two pics, you can see how they have a blue tone to them, and that's the same thing I see on my homescreen/videos.
The second pic is a normal gradient. If this were to be viewed on my phone, in the white/lighter areas of the gradient there would be pink/blue banding. Only the black to white gradient shows the banding, but other colors are still quite vivid such as reds, oranges, yellows, even green. But I do know that it has something to do with light and shading with respect to lcd coloring.
By the way, screenshots of my home screen or any other screen using ShootMe are normal without banding.

I get banding in wallpapers with gradients on my G2, regardless of color. Although it's much easier to see on black/white/gray type gradients. I figure it's just a limitation of the LCD to accurately reproduce said gradients because if I view the same images on my PC monitor the banding isn't present.

Hmm yeah, I get it in everything. Themes, videos, pictures, etc. It seems like there is a color limitation, its annoying.

Did a bunch of Googling, came up with this:
http://www.reddit.com/r/Android/com...rs/?utm_source=twitterfeed&utm_medium=twitter
Long story short, use the Wallpaper Set and Save app from the Market to apply your wallpapers. For some reason it fixes the banding. Tried it myself, it works. Doesn't solve the problems with your video, etc. though.
So obviously the LCD is perfectly capable of displaying images without the gradient banding. My guess is when the gallery is used to set wallpapers the images go through some sort of compression process.
EDIT: Looks like the gallery (Gallery 3D in my case) is the cause of the problem. I tried QuickPic too but it displays banding as well.
EDIT 2: Actually I was mistaken. QuickPic doesn't display banding.
What seems to happen is that when you select an image to set as a wallpaper with Gallery 3D, it saves a copy of it and sets that copy as the actual wallpaper. The copy is compressed, which is what causes the banding. Both QuickPic and Wallpaper Set and Save do not create a copy of the wallpaper, hence why there's no banding. Looks like it's bye bye Gallery 3D.
Thanks for bringing this up, something that's bothered me for a while but never bothered to deal with it.

Yeah im going to continue to try and figure this out. If the Wallpaper Set and Save app can fix the wallpapers that means there must be some sort of calibration that can be done to draw out normal colors from your lcd.
The thing is...the black and white gradients that are affected are part of most images especially videos since gradients are transitioning all the time as the image moves.
There has to be sometihng that can fix this gradient transitioning problem for the black and white shades.
Thats where im at. :S.

Update:
I applied the above black to white gradient pic as my background using Wallpaper Set and Save to use as a test to whether it would get rid of the banding and...
IT DID NOT WORK.
My LCD still displays pink/blue banding along the transition from black to white. It must be some sort of damage that my phone sustained possibly though the 1. LCD screen connections to PCB, 2. The PCB circuits (under the shields), 3. Or the Flex Cable.
****, I need some ideas on how I can fix this...

Indeed, you might have some damage.
I downloaded your black to white gradient image and set it as my wallpaper with both Wallpaper Set and Save and QuickPic. Both times no gradients or color banding was present.

Screen Brightness Dynamically changes...

Hey everyone,
I've been playing around with my new phone for a few hours now.
So far, I love it!
However, I have noticed a strange bug. The browser seems to be dimming webpages.
To see what I'm talking about:
1) Open google.com
2) open the tab viewer
3) click on the google tab - it expands to fill the screen
4) as soon as it fills the screen, the page immediately 'dims'
As it is filling the screen, the background appears nice and white. However, once it completely fills the screen, the background immediately dims to a darker white...
VIDEO
Google Bug Report
https://code.google.com/p/android/issues/detail?id=23765#c0

OK, this isn't just limited to the browser. It happens on pretty much every app with a white splash screen. I.e. opening Facebook. The splash screen is nice and white, but when the content loads, the white background becomes dimmer and more gray...
Does anyone else know what I am talking about? I'm on 4.0.1 if that matters.

The phone dims purposely. I. Don't know if there is a setting to stop it though. I believe it is powersaving feature. Touching your screen resets the time for dimming and screen off though.

I'm not talking about the 'about to go to sleep' dim. This is a very slight, almost unnoticeable, dim when the white animation completes. For example, say I open an app that has a white splash screen and a white background. The app opens with the very white splash scree, then as soon as the content loads, the very white background 'changes' to a more 'off-white' or 'gray' color...
Can others please chime in? I really want to look into this bug, but I need to know if it is limited to me.

This is crazy now. Open google.com on the browser. Then tap the search bar (on the webpage) to bring up the keyboard. The white background of google.com becomes whiter when the keyboard opens. Close the keyboard with the back button, and the background becomes dimmer again.
Even the status bar partakes in this "dimming" action, so it is not limited to the web page.
WTF?

I see this too, it looks like it is caused by dynamic contrast adjusting the contrast based on the picture.

Anyway to keep the contrast the way it is when the keyboard is open? The whites look so much better that way...

I noticed this on my old Droid Charge as well. Maybe it's a Super AMOLED thing?

I'm not sure... Contrast is pretty bad when the screen is predominantly white. However, as soon as some darker colors are introduced (menu/keyboard), the whites brighten up and contrast improves.
Could this be because the all white screen draws more power than a screen that is only partially white?
Go to a mostly white screen (i.e. Google.com) and slowly pull down the notification bar. You will see that the white of the webpages gradually becomes brighter... This is really bizarre...

Good way to test is type in about:blank into the browsers address bar for a full white page.
My gnex does it as well I've never noticed it before but now I can see it its going to annoy me

It originally annoyed me. However, I probably will get used to it in a couple of days.
I was originally worried that it was just my phone doing this (due to the lack of replies on this thread). However, now that is seems like this occurs on all GNs, I'm pretty relieved
Whatever, this screen is gorgeous when displaying colors. Black-on-white contrast could be better (i.e. black text on an all-white webpage), but it is good enough...
I'm still wondering if it is hardware or software that is causing this. If it was software, I would definitely like the higher contrast white all the time...

Mine also does this D:

I think the galaxy s2 and other Samsungs like the note do this, but it is by design from the setting which can be turned off. It supposedly is for power saving of bright colors.
My question is any GSM nexus user seeing this? Cause I attempted the steps in this thread in a dark room and dinr notice any issue whatsoever. Is this a Verizon version issue where maybe all lte versions have this enabled to conserve power?

So then we should be given control over that. The stock GSII had lots of control over the screen color, and power saving features.

Pink stripe down middle of screen

On my E4GT, when I turn the display brightness really low with my ScreenDim app, and then look at something (e.g., a PDF file) which fills the screen with a white background (and black text), while being in a dark room, I can see that the middle third of the screen is slightly pinkish, forming a pinkish vertical stripe, instead of white.
Does anyone else have the issue? If you want to try to see if yours has the issue, you can use ScreenFilter and turn the brightness really low, or you can use the free ScreenDim Trial and set to 25% or a bit lower (in Easy Mode). I'm wondering if I should return the phone to the store, or if they're all like this.

LOL, good for you for being persistent AR.
I tested this for you on mine and I'd say mine is a little over half on the left side as what you described.
Edit: Title is a little misleading but your initial comment about the whole left side of the screen seems to be correct.

Sounds like a symptom of the application. I have not seen a single et4g with a pink line/screen come through my service and repair centers.

This is something you wouldn't normally see in a stock scenario. The lighting app allows for drawing the screen down below 25% and the discoloration is very faint. I wouldn't probably have even noticed it unless I was asked specifically to look for it.
I don't think AR was pointing it out as a problem. He was probably just curious if anyone else could duplicate it using the same setup (well, and to make sure he wasn't really having an issue too I suppose ).

No, I don't think it's a software problem. The app lowers screen brightness to the lowest level allowed by the OS and then draws a light gray overlay over the screen. The device isn't rooted and the app uses standard documented apis. None of this should produce a nonuniform effect like this stripe. In theory, the same issue should come up if one turns the brightness to a minimum with the OS settings and them loads a light gray image. I'll see if I can produce it.
Also, you only see the effect well if you are in a quite dark room. But since I like to read in the dark, this matters to me. If all units have this, I'll live with it. But if it's only mine, I want it to be fixed.
This issue is one of the reasons I haven't rooted: I may need to return the unit.

You are right. I would want to know if it is my phone or not before I make a decision to have it replaced. What if the replacement phone not only has the same issue, but a couple of new ones as well?

Here's a test that doesn't require any special app.
Turn off automatic brightness and set brightness to minimum.
Then view this test image with the browser
http://pruss.mobi/test/A0.jpg
Zoom until it fills the screen. Go into a dark closet or other windowless room without lights. View the screen from different angles. To me, the discoloration is most visible if I view it in portrait mode, straight on. It disappears if I tilt the screen side-to-side a bit. Here is an attached copy:

Hi AR. I tried it out again but I still do not have a line down the screen. I tried several screen brightness levels all the way to 0% where I could barely see the grey and still no line for me. Hope this helps and hopefully someone else will try it for you too.

The other issue my screen has is that if I view a 100% black image, and go into a very dark area (when I tested this most thoroughly, I was in a closed, windowless garage at night), and let my eyes get adjusted to the dark, eventually (after a bit of dark adaptation) I see an gray glow from the screen, with many irregular small patches that are completely black peeking out of the grayness. This is a very small aberration, but it is noticeable when outside at night running an astronomy app.

Interestingly, after a couple of months the problem seems to have decreased. Or my brain is screening it out.

Screen and black levels WAY too black?

Compared to my N4, the screen has deeper blacks, but in a very bad way. You lose so much detail on some pictures, even at full brightness. Like with a picture of black fur my N4 will show all the nuances and shadows caused by the fur, but the Sony will just be pitch black. The amount of detail is pretty significant. Overall, the tone of the screen is just darker, and it kind of makes you sad using it.

I have the same opinion, this is the most annoying thing on this phone. I had very strong feeling to return it back to the shop.
Any solution for this? I can increase screen backlight, but it is not ideal solution and it does not solve the problem.

Upload the picture please.

Yes, blacks are heavily crushed on this device. Here's an earlier discussion of it with links to calibration testers:
http://forum.xda-developers.com/showthread.php?t=2646749
See Erica Griffin's mini review where she discusses the calibration problems and charts the wonky gamma levels here:
http://www.youtube.com/watch?v=a7tQ5n32no8#t=564
If you don't want to install the Display Tester app, here's a link to a black level test image for viewing in your phone browser:
http://www.lagom.nl/lcd-test/black.php
Ideally all of the black squares should be distinguishable to ensure proper reproduction of detail in shadowed areas of an image or video. With Nexus 5, for instance, squares are distingushable from square 2/3 upward.
For Sony Z1 Compact with JDI panel, squares are distinguishable only from square 7 upward. Result: all black levels below 7 look the same on the Z1C, meaning no detail can be distinguished at these levels. One consequence is that low light photos look very inaccurate compared to how they'll look on other displays - if you share or edit them, for example.

I have exactly the same feeling, im from a nexus 4 too and i try to watch some movies on my Z1C and the contraste is juste horrible.
Any ideas on how to fix this?

This has nothing at all to do with the brightness of the black levels. This is about how many black levels can actually be seen with this screen. And yes, this is a legitimate complaint.

This exactly. And thank you for your previous post, it was extremely informative. I was really hoping I just had a faulty screen because I love the phone otherwise. I really love sony's products but the screens on the Z1, Z1s, and Z1c have all been problematic, particularly in dealing with blacks and whites. I really hope these problems are addressed in the Z2 because I really need a replacement for this N4.
Edit: So this affects JDI panels too? From what I read, the JDI panel is much better than the AUO panels.

This is mine, JDI panel...

Heh, remember that there's little point taking a screenshot for comparison unless 1) you shoot it with a camera that has accurate black levels 2) you view it on a screen that has accurate black levels. Otherwise we're all just looking at different things.
Useful info to share in this thread would be how many black levels from that test page you can actually see on your screen (i.e. the number of the last square you can distinguish from another).

Edit: Argh, sorry, my mistake, it should have been 7 instead of 13, as stated in the original thread - corrected now. You can only really see those levels at full brightness in a dark room, though. More detail is lost at normal brightness levels where you aren't being blinded by the whites.

Have to agree, black levels are way too dark. You lose loads of detail in any dark scene, video and photos. Also gamma levels are far too low, at about 1.6 across the board. They should be around 2.2. I'm coming from a galaxy s2 which now seems to have more accurate colour reproduction. Which is disappointing considering it's a super amoled screen vs an ips panel.

Excellent. I can now see it from box 1. Not sure about battery draining though. So disabling the app for now and waiting for an actual fix in the next release. For some reason, I am very happy that it's a bug in the configuration settings and not an actual hardware issue. Sony has again succeeded in screwing their awesome specs with a ****ty software.

It's not a bad thing, I can assure you most Note 10/10+ have different screen calibration.
I have 3 S10 5G and the white looks different on all of them, lol. As a matter of fact even the native ONE UI dark mode looks different on all 3 units as well

This is clearly not a calibration issue. As I said this happens only in the evening time as if blue filter kicks in eventhough the filter is off. During day time the screen is white as usual.

Settings» Display»screen mode» vivd» move slider a little bit to the cooler side. Then go to advanced settings: turn down red, set green to about half and leave blue at full. Or adjust to your liking.
I've been making these adjustments since the note 8 but the note 10 seems more on the red side than normal.

Yes, thank you, that's what I did but I'm still looking for an app that allows more fine tuning

This is clearly not a calibration issue. As I said this happens only in the evening time as if blue filter kicks in eventhough the filter is off. During day time the screen is white as usual.

Just did a factory reset, and this issue is gone. Probably something wierd happened while restoring from Note 9 backup.

I had this issue too, at 8:30pm, and it affected Google Photos and Samsung Gallery.
I had a OnePlus3 and had the bluelight filter set to 8:30pm.
My fix was to go into Google Books, open a book, click on Aa and turn off the filter. I never use Play Books, so it was very perplexing.
Therefore, I'm convinced this is a hidden Android system setting that is no longer accessible and carried over from the Android restore process. I'm happy to be rid of the problem though.

You were right. I just downloaded the Play books and found out that night mode was set to "automatically".

It is a well known fact that restoring from an older or former device often results in certain conflicts, as the settings and other componets are different between devices, this I've heard since my note 3 days
