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:
http://forum.xda-developers.com/showthread.php?t=1377410
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

[REQ] N9 lockscreen mod

Hey guys!
I recently sent my Nexus in for repairs, and borrowed a Nokia N9 from a friend to use meanwhile. Now I've got my Nexus back, and there's one thing in particular that I miss about the N9 - the clock and notifications on the locked screen.
If you haven't used or seen an N9 in action, this feature is really, really useful - and something I think could be ported to (at least) the GNex.. See attached images
When the user locks the screen, usually on other phones it just goes plain black. On the N9 however (because of the AMOLED screen) the screen is mainly black but with the clock still visible! It also shows small icons to alert the user of new messages and such. To avoid burn ins, the N9 changes the position of the clock and notification icons randomly. It also uses the proximity sensor to "know" when it's in a pocket, and then turns of the screen completely.
So devs, can this be done?

wouldn't this create burn in on the screen? Are you serious that the n9 screen never turns off fully?

Well, to be honest it probably would create burn ins if the screen were on 24/7.. But Nokia has (seemingly) thought about this! (And I have failed to mention it in the 1st post )
The N9 changes the position of the clock and notification icons randomly. It also uses the proximity sensor to "know" when it's in a pocket, and then turns of the screen completely. This way it avoids burn in

Not exactly the same but give it a go

Don't know if it will work with ICS and the Galaxy Nexus btw...

This is what I'm looking for! It works pretty good, although it cannot turn of the software buttons in ICS.. But an update to the app could fix that
Danke viel mal!

You're welcome

Crazy! Im interested now

Well, using the stock clock on ICS, you can set the phone into a very dim low power mode (as you mentioned). I am pretty sure the clock periodically moves around the screen to avoid burning too. It also hides the softkeys. You just need to tap the screen when it's displaying the clock overlay and it'll dim down.
I doubt it'd be viable for carrying around in your pocket due to the fact that your phone is obviously not locked in this state and it hides the notification bar so you don't have any visual feedback for notifications (besides LED flashing?). :/

Yes, the ICS standard alarm clock offers similar functionality.
As I wrote a few posts up, the N9 always displays the clock and notifications when not in a pocket (or when the proximity sensor is not blocked). But, if you take the phone and put it in your pocket it will completely turn off the screen - it would be a waste of battery to do otherwise.
Regarding the notification bar, the N9 also has icons on the lockscreen as any Android has in the notification bar - it's only showing a small SMS bubble under the clock if you have a unread text etc. etc. You wouldn't loose any functionality with a mod like this, only gain moar

Yeah I get you, I'd also like this mod, I am quite often finding myself turning the phone on to get the time/see notifications so something like this would be schweet.

Would be an awesome mod. Gonna follow this thread n see where it goes

Thinking this needs to be seen again I'd love this so much, and I'll help out if I can.

NoLED is a nice software. It must be updated to hide the soft buttons as I can see now
My only concern is the battery consumption because the Android OS is not going to deep sleep mode if the screen is on which means the phone is always awake
Any ideas

This mod would be sweet. I had an old Nokia n95 and like that the clock was always displayed with the screen off.

Any ideas on how to accomplish it? Being able to double tap the screen to unlock is really a luxury I would miss

that's a feature of noled and the most efficient way to unlock the phone. especially if you have noled show a clock at all times as well as with notifications. did cut my battery life by about 15-20% but with some tweaking of settings i got it down to only 7-10% which was acceptable for the added ease of use.

[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!!

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.

Weird "light bleed" effect on home screen only...

I know this isn't really light bleed, given its an AMOLED screen... But when on the home screen with a black image, there is what looks like light bleed across the top of the screen. This only happens on the home screen. Any ideas?

I have the same effect up top... It's like the notification area is glowing a bit so you know it's there.

If you took a screenshot of your phone's screen and the effect is there, it means it's not your hardware. Screenshots don't actually capture what you see through the panel. Just like you can't see burn in with a screenshot you can't see light bleed or any kind of panel deformation as well.

Yes, I understand it's not hardware... But it's an issue none the less...
You can see it in the top of the image I attached in my original post. It is only persent on the home screen, and it's really annoying. It's extremely obvious with a black wallpaper.

Yeah it's that particular wallpaper of Pluto or Earth. I get the same thing. In fact, try sliding over to the left where Google news feed is and put it in between screens. You can see it sliding to the top. It's even more pronounced when you switch the display theme to daylight instead of automatic.
In other words, Google has to fix their wallpapers. Nothing to see here. It's not light bleed and I would change the title of this thread to make it less confusing.

It is not just the Google wallpapers... It is literally any wallpaper that's dark enough.

Then it's the Google launcher. The point is there is nothing wrong with the display.

I'm well aware is not my hardware. Read my original post, I clearly said I know it's not the display. Light bleed is not possible on an AMOLED screen... And also not selective to the home screen only.
Just because it's software doesn't mean it's not an issue..

It's not a bug, it's here to prevent Burn-in. It's also visible on the bottom. I saw it with a grey wallpaper, I didn't see the line of the nav bar but on the home screen I did. Like I said, it's here to prevent Burn-in.
