Bright lines on Deep Grey background - Screen Issue - Lenovo P2 Questions & Answers

Hi there, I have bright lines on middle. And I see clearly on deep grey background (like Mobile Yandex Browser tab session). Anyone has experienced this issue?

Another form of banding. Can you replicate?

Set wallpaper to black or go to a pure black screen with no icons on it. Bring up the "recent apps" and clear it out so that the overlay is blank. I notice heavy banding when the app is brought up over a pure black screen. Anyone else notice this?
it's hard to notice in a lighted room. go into a very dark room and you should see what I am talking about.
I've noticed this on transparencies. Could be a low quality image they used. Google has been known to limit the colors available to specific apps. Gallery and the Browser usually display crappy gradients. Perhaps this is another form of lowering the image quality so it loads faster.
As far as what your talking about, yes I can replicate it. Horizontal "sections" about equal distance apart. Hardly noticeable. I have to turn the lights off to really see it.
As long as the screen looks amazing when I'm using it and not in a dark room at weird brightnesses, I'm happy. This screen is super vibrant and bright. Who cares about a little banding on an almost black transparency that is requires a pitch black room to see.

Is my screen bad?

When I put an all-black image on the screen (e.g., using LCD Test), while I am in a dark room, I see a faint gray glow from most of the screen, but there are also irregularly shaped areas of the screen that are blacker and don't glow as much. This is annoying when using the device at low screen intensity in the dark (with my ScreenDim app, for instance), or when using an astronomy app as I was tonight.
Do other people see the same irregularity?
I prefer the darker areas. There shouldn't be any gray glow where there are no bright pixels.
Another thing I noticed is that if I turn the intensity way down (with ScreenDim's contrast setting--Screen Filter should work the same way), and I mentally divide the portrait screen into thirds with vertical lines, then the middle third is a bit pinkish. Is that normal?

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.

Mine goes really green (greys) at low brightness.
@mattabyte can you please check this too? Check it in a very dark room/night at low brightness (not the lowest). And please report here.

one plus providing fix for this on next ota plus ram fix tooo so wait
Yes, I get this. I also get purple trails.
This can't be fixed, I don't think, unless they raise the lowest brightness. From my searching it looks like an issue with quite a few older AMOLED phones.
Well, greys would become pink on my Nexus 6P as well. But for it it turned green which looked really weird. I sent in for a replacement.
I have a slight purple tint to some grays on low brightness, yes.
I also have blue/purple trails when dragging black items over a dark background on the screen, visible on all brightnesses but much more so on low.
Yellowish screen
I also have a little issue with my screen. My screen gets yellowish on the left when the background is grey, this don't happens when another color is shown...
Is this a software issue and can it be fixed or do I need to return the phone?

I made a video showing this issue.... That clearly appears on grey backgrounds.
Do you guys think that the upcoming update could also fix this issue ?
I also have yellowish tint on the right side of my screen

Yes, display uniformity problems are unfortunately very common on the OP3, as also a thread in Oneplus' own forum shows (with a poll). You have to return the device for a replacement as often as you need to finally have a device with even screen.

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).

On picture we could clearly see green tint defect
Yep, and it looks like software issue to me.
Screen pics
As you can see, app is a little green, but quick settings are black when dragged down. Screen is fine, I believe.

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?
