[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.

This is same like what happen to OG note..i thought sammy already solve the problem when they using RGB instead of pentile on our note 2.. this is not good...
I check mine, so far nothing yet. But i afraid now!!

I also thinked that it won't happen on Note 2 too ,but here it is.I'll go further and I'll send it in the service ,after my holiday ends.This thread is good to maintain active because it may help people that also came along this problem

I always set brignest to auto and screen movie mode. So maybe it did save mine from that problem

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>
Unfortunately, Camera has stopped.

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] Background color for Google Play Books with T700

I use my Android tablets for reading, using Google Play Books. I prefer a bright white background. With my Nexus 7 (2013) it's a pure white background, just the way I like it. With the Tab S 8.4 I can't seem to achieve bright white. It's more like a light sepia. I know sepia is a choice but that's a very dark (to my eyes) background. I've also played around with the Screen Mode but none of the choices seem to change the GPB background at all. I've turned Reading Mode on and off but I don't see any difference.
I know there are other reading apps but I like having a large library stored in the Google cloud and the ability to switch devices and have the bookmark change with it.
Any suggestions on how to change the background color for just Google Play Books?

I'm having the same problem with my Galaxy Tab 4 7.0". I've tried everything you have and it also doesn't work. I've also noticed that when I click the home button on my device it turns bright white just before closing so I know that the app and device are capable of displaying the correct color.
I know this isn't an answer to your question, just letting you know that you're not the only one. In fact your post is the first I've seen about this issue and I've been Google searching different variations of the question.

Those are my settings, and whites are white as should be.

I seem to get better whites with Basic rather than Cinema. When I use Cinema white has a strong blueish tint, especially on video. Whites on Basic are fine while watching movies, YouTube, etc. Google Play Books is now better with Basic and Reading Mode off but it's still not as bright a white as I would like.
For example, I was watching Ex Machina. An early scene has a helicopter flying over a glacier. With Cinema it looked like a sea of blue. I changed to Basic and the snow and ice turned white. You lose the oversaturated colors with Basic but the blueish whites really bother me on the other settings.

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.

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 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.

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.

color change from lock screen to unlocked phone

Hello, I'm facing a sort of problem. When I look at the locked screen it has a calibration, but when I drop down the quick toggle or I unlock the screen it turns a little bit more yellowish. I don't think it's hardware related but could someone give me an explanation?

I think it's because of the FP sensor. To improve the recognition maybe.

Or it is a bug like the dark theme not being dark in some apps, Chrome, YouTube, Shelf. Top of the screen is less dark, like a little bit green. Not a hardware issue though, settings and built in apps ark dark (Dialler, Messages). I think it is something with the theme settings.

It's all normal. The lockscreen has this colder/blueish tone, like a filter, which goes away after unlocking. Nothing to worry about, not a bug or a defect. Just the way it's designed to work.

I don't think so.
With every app that request fingerprint authentication the color of the screen changes.
It must be something related to improve fingerprint accuracy

I am not talking about the screen with FP scanner active. Just check the dark themed Chrome, Shelf, YT. Especially on the dimmed screen. Upper part is a little greenish. Cannot make a screenshot as it looks ok on it. It has to be sth with theme, as on some apps (dialler, messages, settings) the whole screen is dark (black).

Thats because green tint is only visible on certain brightness levels at grey background. No problem on black background

The issue related to the lock screen is present any time the through screen fingerprint camera activates. You will also notice it if you have face unlock active in low light and the screen lights up to assist the front camera in recognizing you. Color spectrum is super important to cameras when they are recognizing things on our skin.

That apps are not black, are grey. "Dark mode" does not mean "black".
In other way, all amoled panels have (or can have) this kind of behaviours at very low bright level and certain colours (especially grey).
Particularly, I do not see that effect in mine or I just cannot see it.
If you think that is a defect or problem, why not open a repair request to OnePlus?
