[Q] Gradient banding problem, help? - Samsung Galaxy Nexus

I'm not sure if this is the right forum but I am almost sure it is...
Anyway... I notice that certain gradients on my galaxy nexus have really visible bands in them like they are 16 bit color (these gradients being the backgrounds in settings, music, phone, people). I can see them on my galaxy tab (10.1, running cm9 kang) but that doesn't bother me because the display isn't as bright so I have to look really closely and its not really as much of a problem as it is on my galaxy nexus. I originally thought my gnex's display was defective but now I realize it is just the ics ui in general as it can display gradients in the browser and gallery fine. I have cm9 on my gnex as well, and it has a dithering option but this doesn't seem to affect the gradients in question.
I also notice small 1 pixel bands running across the display (most visible when on a black background like the app drawer) when the task switcher is open.
I put screenshots on my flikr (and increased the brightness of them as its hard to see on a lcd display) here: w w w . flickr . c o m /photos/[email protected]/ (if anybody can suggest a better place than flikr feel free to tell me, and sorry for violating the no links for noobs rule, you will have to take out some of the spaces in that url ).
Any ideas on how to fix this? I can't find anything about it anywhere?

I have checked that thread before posting this and my device doesn't look anything like those in the pictures that are 'not okay'. I was originally certain I would have to return the device until I noticed the banding in screen shots when looking through them on my computer... You may be right though, so I'll compare with some other gnex's next time I have time to go to an o2 store, but I strugle to see how something visible in screen shots can be a issue with the display...

Dirty screen effect

Hi guys,
i did a search but have found nothing regarding this kind of problem.
My display shows some kind of pattern on plain colors.
http://dl.dropbox.com/u/16054199/screen.jpg
Its worst on grey and white, (certainly) not seen on a black screen, and its almost not visible on the highest screen brightness. But, its very distracting on everything below and also visible in pictures etc. if looked closely.
I come from a S2 which had not this effect. Is it a faulty screen or a normal effect of the pen tile matrix?
I see the same thing when my screen dims down before it goes to sleep.

Just before it goes into sleep mode? (which afaik is even darker than the darkest setting while it`s awake).
I clearly see it under medium backlight setting, the grey elements of the market are a place where i always see it.
hate to break it to you, but that's just how the screen is(especially when the brightness is turned down & on plain colors). i've had 2 Nexus' and both did the same, even the ones on display in my local verizon store are the same way.
Turn the brightness up and it will go away. It's a quirk of the screen technology.
Allright, so i have to live with that... Thanks for your answers!
Is it possible to edit the levels of the automatic screen brightness?

If you're rooted and have Clockworkmod you can use this:

Just make sure you meet the requirements and follow the directions in the thread. I have used this on a Verizon LTE Galaxy Nexus and didn't have any issues, even though it is in the CDMA form.
I am not the dev of this mod, just passing along the info.
awesome, thanks a lot!
I wonder if there's some kind of deeper hidden meaning to the pattern, some kind of subliminal message jk

[Q] Is there anyway to adjust the brightness on the browser & other applications?

I came from the Galaxy Note to the GNex, and on the Note you had the option to turn off the feature where if there's a lot of white on a page, the LCD will automatically dim to conserve battery life (at least I think this is why it does this). Also, you had the ability to control the brightness of the browser. On the GNex, I don't see any of these options to control the brightness of the phone, resulting with the browser looking a lot dimmer than the rest of my phone (especially when I load up sites that contain a lot of white area like Google or Facebook). The issue isn't isolated to the browser only, but even in the Facebook application (aside from the Facebook website), since there's a lot of white area, it looks dim and kind of washed out.
Is there a fix or work around to this? When I put the Nexus beside my brothers iPhone and do a browser brightness comparison, the Nexus looks so dark and blah...
Thanks!
There's no way to turn it off on the nexus. But I swear I can't see this dimming like other people can. Is it only on the Verizon one maybe?

[Q] Note 2 screen problem?

I bought my phone from an online store in Romania on February 22.I have warranty and other things, it was brand new. I kept the screen on full brightness, and Dynamic color mode. That's how I like it. I was aware of burn in so I switched colors with a display tester every 3 days or so. Yesterday I noticed that the spot where status bar is used to be in portrait mode is brighter than the rest of the screen when displaying blue, white and grey colors. Brighter not Darker. I searched on Google images and that doesn't look like burn in. It wasn't here until yesterday when I spotted it. It's barely visible with display tester but in Games videos photos and multi colored things it can't be finded, You need to look with max attention. I used Nova launcher to hide the status bar. I also heard that there are 2 different things, image retention which is fixable and permanent burn in. I searched for something like this but I don't seemed to find something good. I don't know what it is,I never browsed the Web without changing the pixels where the status bar is for more than 20 minutes. I heard burn in occurs in extreme cases. I don't know how this happened so that's why I'm asking you guys. I don't know even what to do it bothers me only in display tester, but otherwise the screen is perfect. Please give me an advice because I don't want to have a faulty screen.. Can it even be repaired under warranty for that?
No one knows what's the problem?
Maybe you could post a photo ?
Look at the top of the screen...That's actually what I'm seeing when looking on a blue test background.This kind of discoloration/brightness where the notification bar usually is when in portrait mode.This is not a screenshot or photo ,it's just a blue image that i modified to show about i'm talking about.It also happens on grey and white and cyan .I couldn't take a photo because i have a crap 7 MP shooter ,and one crapper 2 MP shooter on my old Galaxy Y.I tried them both but noone of them can catch thatstrange discoloration/burn-in/brightness
Xda don't let me to post links..That's the link without the X'es so delete X from this link to go to the image hXttp://i4XX4.tinypic.coXXm/2w4g39j.jpgX
I really don't know what this can be.
I have the same problem! I noticed it a few weeks ago. The bar on top, when in full screen mode, is slightly brighter/lighter compared to the rest of the screen. I can see it the most when using the browser. The screen looks slightly more yellow compared to the grayer (or something like that) bar. Remember the bar is not actually there, just the discoloration in its place. I have no idea what is causing this and I'm hoping it's not hardware related.
It ain't hardware if it shows up in a screenshot. Looks like the exact dimensions of the status bar, almost as if it's compositing it or it's shadow placeholder where it expects it to be. Try a different ROM, or install the Simplistic Framework and try changing the status bar's colour and transparency setting, see if it makes any difference.

I wrote that.It doesn't show up in screenshots.I edited a blue picture to look exactly like my phone screen.The problem I think it's the screen itself.And the reason for why I edited a picture is that as I said my shooters can't spot it.Any ideas?Also I use the stock ROM ,un-rooted..Everything stock ,including the notification bar.I just have a custom launcher wallpaper and widgets...
It shows up when you turn the phone in landscape mode as well. It remains on the side as a vertical discoloration where the notification bar resides when in portrait mode. I'm not pleased to say the least.

Exactly what's happening to me.
Made in china phones r crap..made in korea by samsung is gud quality
If you have the warranty the warranty, why not use it? Since the problem is from the phone itself.

My phone was on Dynamic and Full Brightness all the time.I love oversaturated and bright screens.LOVE AMOLED <3
Well I found a solution to the problem. It takes time to pull off and is still a work in progress for me but it's working.
I created an image that matched the resolution of the phone screen. I then made a rectangle at the top of this image that presents the exact size of the status bar and colored it white. The rest of the image was colored black.
I installed an app that keeps the screen on without dimming when plugged into the charger. Overnight I display the image I created with the screen set to stay awake and don't dim at full brightness. So what you see is a black screen with a full brightness white strip where the status bar is supposed to be.
This process quickly "ages" the status bar area and it slowly starts to match the rest of the screen. I've been doing it for almost a week and the difference between the two sections of the screen is starting to diminish. I bet a couple more weeks of this and the difference between the two sections will be gone.
I got the problem as well. And I'm telling as many people as I can because I'm annoying like that. Seriously, I hate the fact that I spent such money on faulty phone...Samsung galaxy note 2. <blech>

Samsung Galaxy Nexus - Blue Line on Screen Edges Issue

Greetings,
I just purchased my Samsung Galaxy Nexus but I noticed after some months of use, some strange blue lines that appears only on blue, grey or specially light colors as white backgrounds. I am very upset since I bought this good cellphone but noticed the screen issue. People told me that those blue lines where just a software problem but the thing is that I recently upgraded from 4.2 JellyBean to 4.4 KitKat and those annoying lines still appear on specific backgrounds. I forgot to mention that those blue lines appear in full-screen mode where the notification and the digital buttons bar are when they hide while in that mode, for example: when playing games, visualizing text or images, watching videos on Youtube (all of it in full-screen mode). You got the idea, right? Its like when the full-screen mode is on and the functional bars of the Nexus fade, it is supposed to be the same color as the whole background, but not; it appears like a tone of blue instead. This has nothing to do with the camera by the way.
I now think that the issue is related to some problem with the screen and hardware. I don't really want to replace the whole screen with a new one since Nexus screens are very expensive. I can't claim a warranty as well.
So, the questions are:
¿Does anybody have or have had the exact or similar issue as me?
¿Can someone please explain me what's going on and give me a solution?
I will leave few images bellow where the blue line is more visible:
1st Picture: When Youtube is loading the video, the notification and digital-button bar are gonna fade to play the video in full-screen mode.
2nd Picture: While the video is playing in full-screen mode, on the edge of the screen where previously was the notification bar, the blue line appeared, you can see it easily.
3rd picture: While reading any type of text or viewing a picture in full-screen mode where the notification and digital-buttons bar fade, the blue line appears again and its very easy to see it.
4th Image: This case is different, on a background with dark blue and black colors, there is some blue tint effect that is slightly notorious, the picture taken from the camera doesn't show it very well.

Yeah dude, it really sucks and its kinda annoying when watching videos or reading something. Google should make something about it on future cellphones!
If you fix it or at least reduce the blue shadow a little please notice me, I am very upset about it. :crying:
My „blue lines” appeared after I dropped the phone
Seems like standard Galaxy Nexus AMOLED burn-in. Try something like this but dont expect too much.
Screen burn in. I have it too. There's no fixing it on an AMOLED display without replacing the screen. This is my first and last device I will buy with AMOLED.

Blue tint on my Galaxy m51 while using dark mode.

I've enabled dark mode on my phone. And while scrolling through Instagram or any other app I can see that when the black region in the photo moves it leaves behind a blue/navy tint. The same is true when swiping the photos in gallery and other places as well. The issue doesn't occur when using the normal light mode. Are you guys also facing this issue?*
You won't get to see it directly. But then if you notice carefully you'll observe this. It occurs mainly when there's a change in colours while using dark mode. Like when there are images, checking for wallpapers on 3rd party apps, social media, etc. Do let me know about it.*
This is really bad news. I avoided the Galaxy A71 for this reason and with your comment I'm now seeing signs that that the Galaxy M51 has those same issues.
If anything I have to avoid grey import websites now because I want to be able to refund the phone if I encounter the same problem.

Update.
I went to the Samsung service center in Bangalore. They checked it out too and were like it's the first time someone reported this. And they couldn't do much about it. Also they showed me a few s9's and some other samsung devices with sAmoled displays and the same blue tint issue was there but a little less. So there's nothing to worry about. But I still kinda feel bad about it. Having to look at it all the time xD

There is, the fact that this issue appears on other phones doesn't make it any better for people who end up with a inferior looking display.
Especially considering that this is the most visible when using dark theme and displaying black in general and 100% black is why a lot of people go for OLED displays.
This actually makes me think I'd be better off with an LCD if AMOLED screens have issues with burn-in, color tint and smearing.
My m51 (brazilian one) have this blue tint thing, and also the screen didn't got calibrated very well, so the white seems to be a little green. So I calibrated it
