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.

[Q] Super AMOLED - Black = off or still on?

I'm looking into purchasing the Galaxy Tab S 8.4, but one of my big uses is for reading on the Kindle app. Currently, on my LCD device I read with a black background and white text to reduce the light emitted as I do a lot of reading before bed, but it still is a lot of light which can keep my wife awake. Does the Galaxy Tab S actually turn off the pixels producing black, or is just very, very dark? I know AMOLED is supposed to turn them off, but I've heard conflicting reports that some devices do and some don't. Would someone be able to load up the Kindle app and set it to black with white text and let me know if it actually shuts off the pixels so it wouldn't be as bright in a dark room?
Thanks!

The Kindle app set to black background truly gives a black background, if set to use system brightness you can also get a very dim white for the text. If looking at something like the dark theme in Tapatalk you don't get black, the background is a dark grey. A bonus of running the kindle app like this is that battery life should be extended, compared to using a white background.

I could say that this is true black. Comoared to my old 7.7 which gives a slight glow when displaying pure black. This one seems like the screen is off

Odd stuck white pixel?

Hey XDA, wanted to get thoughts or suggestions on this.
I noticed what appears to be a stuck pixel on my m8 today, but it doesn't seem to make a lot of sense to me.
Pixel appears to be stuck on (all white), but is only visible on lighter images such as white backgrounds and other lighter colors. Not visible on gray or black images, which seems counter intuitive.
I've restarted several times, run a pixel fix app for about twenty minutes, and verified it's also visible in TWRP recovery, so definitely appears to be hardware.
Any thoughts on a fix, or why it's only visible on lighter backgrounds although is "stuck on" and all white itself? I'd figure it would be more readily visible on dark scenes, but nope!
Thanks in advance for any input.

Im not quite sure how the display works, but maybe the darker images dont activate or light up that actual pixel? Anyways, why dont you bring it to your dealer?

Night mode isn't as dark

Lying in bed last night I turned on Night Mode. I noticed when I pulled down the notification shade, the top portion was still dimly back lit, so I could see the camera cutout and the edges of the screen, no matter how much I dim the backlight.
Well tonight I fired up my Note 9, put it on Night Mode and pulled down the notification shade, and no matter how bright or dim I have the screen, the top part is BLACK. no light. You can't see where the screen ends and the frame begins.
This isn't a huge deal except for battery savings. When an AMOLED screen is true black, those prices shut off. But since the night mode on the N10+ isn't true black those pixels are still lit up and using power.
When viewing video in Netflix or YouTube the black bars are truly black, so I know the screen is capable showing true blacks, I'm just not sure why Sammy changed Night mode so it's no longer truly black.

I have just experienced the same thing. I have a note 9 as well to compare. I'm actually deeply disappointed. I also noticed screen mode only has 2 options... vivid and natural. Where as note 9 has 4 screen modes. I'm trying to figure things out to see if I can get it to be true black.

It's probably normal since it's a night mode and not a black mode ; in which you wouldn't it to make your screen showing heavy contrasted differences that actually made more eye fatigue than the light one.
Maybe I'll finally like this mode on this new phone.

No I understand it's a "Night mode" but I'm comparing it to the Note 9 and Note 8 Night mode where it became a true black. And I ran it in Night mode almost 24/7 for some battery savings as well. Well that doesn't work if Night Mode is just a dark grey rather than a true black.
And I'm not sure how true black and contrast made for more eye fatigue? Have you never watched a 4K movie? The whole point of high def is high contrast with true deep blacks, bright whites, and bright colors.
I also noticed on the quick access home screen in Samsung Browser on dark mode, it's not longer a true black. Now if you turn on High Contrast mode in the browser settings, then the background is a true black, so that panel is capable of turning off the pixels and going true black. This means it was an obvious design choice.

Dark VS black doesn't make much difference battery wise on OLED screens (let me just find the test back and I'll update my post)
Because the notification panel and anywhere else that it matters contains mostly texts and it produce visual retina persistence (not sure if I translated well), plus it's more annoying to read and and eyes accommodate less than in light mode where everything is light too.
There's nothing to do with movies since it's dynamic and constantly changing from a lot of different colours while texts are more static (but going from dark to light scene still hurts)
I agree that it's absolutely a design choice, but in my opinion for the better.

I gotcha. Makes sense. I'd like to see some tests on black vs dark. I had always heard and though the battery savings was due to the pixels shutting off. It's why the AOD is black and not just dark.
Buts also weird. I'm replying to this direct from the Gmail notification of your reply. So it opened up the webpage in the webview. Well the top bar above the page that says reply to topic and has had the Gmail overflow button is true black. But the status bar right above it is dark grey.
I guess what bugs me most is it makes the camera cutout stick out, even in the dark. Because I look up an I see a true black for on a dark charcoal background. And I can see the screen edges. I preferred on the Note 9 where it all just blended away with the true black.
But yet, when I watch a movie, the status bar DOES turn off completely and you can't see the camera cutout. Just can't figure out the inconsistency.

It may be because apps got their own night mode colour settings embedded, while all One UI apps got theirs which are different.
Like, if for Google night mode is all black, their apps will just check about system UI night mode trigger and of its on, apply their own settings.
I can only find that reason for it to be such inconsistent.

That's a good point/thought. I hadn't thought of that. Damn...I just like consistency, LOL.

I totally understand and agree ! Especially when you like what Samsung did with their UI
In an other hand, there's some third party theme that may be of use to have a black theme : https://forum.xda-developers.com/s10-plus/themes/theme-anxious-t3921645
I don't know if it's working for the Note 10 yet but I think it's just a matter of time before it do

I'm using #hex_ and it works very well on Note10+.

I just use a theme that's mostly black everywhere. No need for night mode..

One UI notification shade isn't actually black for any of the devices on the One UI. I had an S8+ before this and it looked black but if you take a screenshot and measure the color value, you'll see that it's not black. You can do the same thing on your Note 9. Take a screenshot and extract the color value. Or take a screenshot and then transfer that screenshot to the Note 10 and view it on the Note 10. I guarantee that the Note 9 screenshot of the notification shade will look like the Note 10 notification shade. Black will cause AMOLED smearing which isn't good look.

So I tried this. Set my Note 9 to Night Mode and took a screen shot. Sent it to my N10+. Guess what? The notification shade in my Note 9 screen shot is pure black when viewed on my N10+ screen.
So I did the opposite. Took a screen shot of N10+ notification shade and sent it to my Note 9, and it appears dark grey.
So I'm not saying you're WRONG, but this is proof that the notification shade on Night Mode on the Note 9 (and the Note 8) was SIGNIFICANTLY darker than the N10+. If they aren't true black, then they are so close at to be indistinguishable from it, whereas the N10+ is definitely lighter than black.
I also just used an app to do a color value sample on my screenshots. Note 9 notification shade is #00000. I believe that is true black?
See my attached screenshots. War Machine is Note 9 (The one with the true black notification shade) and the Darth Vader is the Note 10+ (the one with the dark grey notification shade)
To see what I'm talking about, you may need to turn brightness up on your phone or go in a dark room.

Screenshots of color picker showing Note 9 notification shade is #00000 (true black) and Note 10+ is #080808 (not true black).

I tried this. The notification shade was still dark grey, not black.

Samsung doesn't use black on the N10, it's that simple. They use a form of grey that's fairly close to pure black, however. The avg person probably uses white themes, so I doubt many will take notice.

Look for a different theme. There are black ones. I'd post mine but I can't seem to post screenshots here.

It's all good. I fixed it with GoodLock. I have my stock theme and a true black notification shade again.
Thanks!!

Write back when you find a solution to make samsung browser black.cheers.

As Nastrahl pointed out it the pixels don't need to be completely off to save a lot of power. I was going for total black but since I adjust brightness manually a little bit of tint to the black looks nicer and makes it easier to gauge the brightness.
You can use the Good lock app Quickstar to make the pull down notification panel any color or darkness level you want. Mine is almost black with a hint of forest green.
My wallpaper is even darker with the same green tint.
When the brightness is too high the wallpaper's green tint is noticeable otherwise it looks black.

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.

Don't have this problem on my m31s while using dark mode may because m51 uses csot amoled display?

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
