I have a nook color, I was wondering if anyone notices a very slight screen flicker like a low refresh rate? Most people would not notice. It doesn't bother me much but I wanted to see if its normal. I notice it most on a dark grey background at 50 percent or lower brightness.

Yes! finally someone that notices it! I have been posting this on other forums. I notice it too on dark backgrounds with about 20-40% brightness, Not sure if it can ever be fixed with an update, but it is sometimes annoying, although not highly noticeable.
I have worked with computer enough that I can tell the refresh rate of a crt just by looking at it. If its normal I am not to worried I justed wanted to know if it was defective because ill switch it out before I root it.

I get the same thing, very noticeable when you are changing the brightness setting. I use the lowest brightness to read an eBook, and I can really notice the flicker when I lower the brightness, but I can notice it when I get back to the reading screen.
I see it on darker images...its so subtle I ignore it.

I still have mine stock... but I see it as well.
Anyone that has loaded any other apps notice it in those apps? i.e. does it flicker noticably in Angry Birds? or other apps?
thanks.

I wonder if it being an IPS screen has anything to do with it. It doesnt bother me to much but causes more eye strain than reading from my htc g2. You would think they would make sure an ebook reader doesnt flicker. oh well i can deal with it.

It's not the screen, per se, but the LED's that are lighting it up. From what I've read, LED's can't vary output with respect to voltage (they're not dimmable), so you have to pulse them very fast to change the output. I assume that the lower the "level" the more the LED is off vs. on, hence the flicker.
Dang I can't post links yet...
Go to Wikipedia, and look for :
/wiki/Backlight#Flicker_due_to_backlight_dimming
I'm pretty sensitive to this, but haven't noticed it on my iPad, but apparently it does it as well. I was wondering why the stock lowest brightness levels were so friggin' bright - probably at the threshold of flicker. You can dim more in a browser or ebook app, which is where I see reports of flicker.

While you can dim an LED by limiting the current (either via inline resistors or with constant current drivers), you can only do so to a degree. Below a certain current, they will simply not light even though the current goes through the LED. On high performance LED's this is still at a pretty bright level. So instead you use PWM (Pulse Width Modulation) and vary the duty cycle to brighten and dim the LED. As the PWM is at a fixed frequency, with more or less of the cycle being lit or unlit, once the unlit portion becomes substantially longer than the Lit part, you can detect the "Flicker" if you are sensitive to it. This is usually particularly noticeable in the "corner of the eye" if you pan you vision across the area and the device gets paned across you field of vision.
This is done on all the new LED tail lights on cars as well and I hate seeing them at night, when they are almost making me nauseous from the flicker.
Good info thanks. Makes sense but wonder why I don't notice on my led backlit netbook. Guess every screen is different.
yea I really wish there was an update to fix this, but i guess it's just the screen, funny how I have never noticed this on any LCD screen I have ever had from computer to TV
three nook colors - my experience with flicker
My first nookColor had screen flicker, also a mind of its own with phantom taps. Nook #2. Did not have noticeable screen flicker but did have a handful of stuck pixels. Took it back and picked up #3. No stuck pixels, but I've got screen flicker on dark colors. Find it strange that nook #2 didn't have te problem with the flicker. I don't like the flicker at all but think it may be timento live with it.

Has any one returned a flikering nook color and gotten a better one in return?
Hello, I am having a similar problem with angry birds. My screen sometimes will flash different colors and today the screen stayed completely red for 2 or 3 seconds while playing the game. But other than that I love the rooted nook color. Maybe the graphics chip is not powerful enough for this game.
Firmware update
What you described with angry birds is not the problem I am having. Mine is screen flicker. My eye can basically detect the refresh rate with low brightness or in darker colors.
Tried to change it out. Would say that Best Buy is much easier to exchange things at than Barnes & Noble. Eventually they switched mine out and the new one had a dead pixel. They then let me open two more in store in the store all had dead pixels, so did their display model. All presented in the lower right hand corner of the screen. Would be covered up by the black menu bar normally, but visible when the black menu bar goes away.
Anyway I kept my flickering nook, and talked to someone at Barnes and Noble tech support on the phone. He told me the dead pixels were new to him, but they knew about screen flicker issues. He said they would be releasing a firmware update to address this and other problems very soon.
Just wanted to note that none of these nook colors were rooted.
Yes, same here, I have that on my Witstech A81 (resistive screen) too, more noticeable when the battery level drops. Never noticed this problem on my iPhones or iPad though...can't be Android related can it?

Thanks. I can see the flicker too on gray screens. I have no other issues though (minus a tiny, tiny bit of give on the bottom bezel). I'll wait and hope it gets fixed in an update. I don't have a lot of time to keep exchanging a good unit.
If it is a known issue and a firmware fix is planed, then I am content with my rooted nook. Thanks for this thread.
I took mine back to B&N today to see if replacing it would fix it. Both store displays didn't have any flicker.
They opened two different nooks and they did the same flickering thing.
So I called Nook technical support. He put me on hold for about 5 minutes. He said he checked about 5 nooks and they all flickered. But he hadn't noticed it before.
So, he will put a ticket into the development team to have it looked at.
So, another confirmation that Nook tech support is aware and looking into it.
My first Nook did not display this behavior. I returned it due to creaking issues, and the replacement did display screen flicker.
I'm hoping it's a firmware issue and not a hardware one!
Currently not a big deal though...
Hello XDA users !!!
Just noticed a thin long black line (vaguely seen) running from top to bottom of my screen on total black background i.e Grey (as it turns off all pixels and making the image more brighter on a black background but it's grey & can be noticed on a terminal with green on black option) and similar spots on my SAMOLED screen but there's no problem with the pixels all of em are 100% healthy.The images are clear,vibrant & bright but still this flaw/disadvantage is bugging me..!
And we all know that SAMOLED and SAMOLED Plus displays from samsung are extraordinary & superior over the AMOLED's, LCD's , HTC's RGB 720P AMOLED(Rezound as explained in Engadget's review) as Super AMOLED advantages are brighter screens, less sunlight reflection and reduced power consumption (Source: http://en.wikipedia.org/wiki/Super_AMOLED) but after this experience and some googling i had just discovered that sooner or later maybe all the SAMOLED or any type of AMOLED display users are goin to face this issue/burn-in and even the display will change like this .
but that's an intermediate stage of burn in .
Hope this info was helpful and there is no fix for this unless you get your screen replaced when this chaos x( happens to your phone...
Please report if any one's noticed the same.
Correct me if i was wrong ...!
C'mon no response ..?
I got notification bar burn after the first couple months but to my relief it hasn't got any worse in 18 months... Yay!
**Simply Honey 5.1 JVR rom & Talon kernel @ 1.3ghz**
Hi, I havent noticed any burn-in´s, but I´ve noticed those lines coming from top to bottom. For me it is the most noticeable on white background. I thought that the framerate is lowering down. Also it can be caused by CM7, will try in couple days to reflash back to SammyRom to see if it happens too.

I doubt that's a burn in unless if you have a background with a line running from top to bottom. Burn in looks like artifacts that appears often on your screen, such as the digits for the clock on the status bar.
i run a BLACK theme, and even so i still got the status bar and its icon burned in on my Nexus S
good thing is, it's not noticeable unless you put a full white or full grey background on the screen
it's very easy to check with screen test

Yep, you are correct. Indeed i did mention that all pixels of my display are working properly & that weird problem made me to analyze, post a thread in here that could help many SAMOLED users to seek out any issues before hand with their precious devices

First of all, AllGamer (Moderator ) thank you for your response .
So, all these point out that our SAMOLED's are at a very high risk and even though you had a black theme your Nexus S but still it getting burn in.....
that's very sad .
by the way that app can't be tested on ICS .
I just noted (pardon the pun) that there are lines vertical ans horizontal lines when displaying white. This is my second phone. I went back to cpw and changed this one has similar horizontal lines. Its very very very faint, but I can see it. Im not sure why, it is because of the AMOLED screen, how it works?
Very annoyed. what can i do? every phone CPW has cant be faulty?

I've only had mine a day but cant see any lines like you've mentioned... maybe a bad batch they got in? Maybe something to do with the S-pen's digitizer screen, i assume that will have some form of grid to it
AMOLED seems to have weaknesses at low brightness levels.
Some have seen very faint lines .
Also on minimum brightness some reported a faint changing of the hue of the display.
The screen is also very bright (whites) on min brightness.
If you display a greyscale step pattern black is absolute black but
others that should be near black are too bright.
http://www.execulink.com/~impact/docs/utils/StepGray16G.jpg
I think its just the AMOLED tech but check the display thread too.
In normal use the screen is amazing,
all technologies seem to have good and weak points if you look for them.
You are not the only one with this problem. I'm on my third galaxy note now... The first one had dead pixels and the right side was darker than the left side. The second one had much more dark horizontal and vertical lines and smudges. The third one at first had very faint lines and smudges, but it is becoming more visible now. There are several threads about this issue on this forum.. My guess is that these problems are pretty widespread (more or less visible on some gnotes) and that there were some bad batches or that the Amoled technology is the problem. Would love to hear the reason to these issues from Samsung.
No lines on mine. White is white and everything shows up excellent.

If you disable the automatic light control and just snap the backlight up from 0% to anything above, you will not see any grayish things in video on the Note. I don't have this problem, but I've heard that some people have had to do this to solve this issue.
I don't have any bandings or strange lines anywhere on the screen. It looks as good as my Galaxy S II and Galaxy Tab. I haven't seen anything out of the ordinary (considering the limitations of the AMOLED screen).
There have been concerns about the lines on the white though. I don't have any of those on mine, but it seems some screens show up this fault. I don't know how to solve this issue and would recommend returning it as soon as possible.
Using the recommended gray test on the Note didn't show up anything but a solid grey screen on mine, although I've heard much people have dark spots all over. It might be something about where the phone was manufactured, or when.
My Note have never had anything wrong with the screen or anything else. The only problem I've ever had is applications that use 16 bit color instead of the Notes 32 bit. This will make color look strange at times, but it's totally normal.
Note that this isn't something wrong with the hardware, it's merely a software problem that will be solved as soon as ICS is released.

I have yet to see ANYTHING with more then 65k colors, even in the browser.
All i see is some VERY clever dithering very hard to see due to the high resolution.
Coming from the HD2, I'm really disappointed, nothing gained in 3 years (well, more pixels, so harder to see the flaws).
I took 3 picture with a green gradient:
1) 1280width, so basicly 1280 levels of green, but 24bit only shows 255.
2) 255width, so basicly 255 levels of green, 24bit.
3) 64 width, so basicly 64 levels of green, 16bit.
They all look the same to me, in browser and in gallery. I see dither in each of them. This tell me the whole screen is 16/18 bit only.
Maybe the PenTile is playing tricks with me...
Or the grainy screen lets me think its dithered...
i am facing a similar problem..whenever i apply some photo having a lot of black in it as my lock screen image..there seems to be some horizontal gray lines in it..but when i look in the gallery the black is pure black (no horizontal gray lines at all)...is there any problem in the software only ? or is it something regarding the screen?
All my screen burn in complains started with LPY ICS. Suddenly I noticed bluish color in place of status bar(top of screen) while reading web on landscape.
Later, it change to situation like on screen test status bar location seems to giving best color. Rest of the screen has yellowish tint now.
So my screen is acting weird or getting broken. Anyone else has this issue?
I want to go back to GB, but I am afraid to brick. If go back to GB, should I choose non wipe GB for mobile odin?
I have CF-Root LPY kernel.

Screen Burning?? This is kind of hard to believe, at least that ICS is causing the problem when there is a lot of people on ICS now with no problems like that. Just a defected phone probably and you should try to return it to Samsung if you have a warranty.
But, I would recommend using PC Odin to go back to GB.

It's not a defect, it's just an unfortunate side effect of AMOLED screens.
This is discussed extensively on XDA, particularly in the I9100 forum.
Your best solutions are preventative ones, use a launcher to hide the status bar, leave screen on minimum brightness, avoid leaving the screen on for excessive periods with still images and try not to leave it in direct sunlight (on or off) because this damages them too.
To be more correct, this is actually not burn in, it's the organic LEDs wearing out, the longer they are lit for the more they wear out over time and the less bright they become. Because status bar is black, they get used least and so end up brighter or tinted, and pixels used most (clock area or lock screen circles) get dimmer.

I was on fully stock LPY and I noticed almost the same thing. What appeared to be dead pixels in the shape of one blue dot and one red dot formed on my screen. Though only visible when the screen was OFF for some reason. Anyhow. I flashed back to LC1 stock odexed rom via pc odin and my screen was back to perfection. Well, if you disregard the black clipping issue

Yes, I think it is as you said. Screen colors dimmed. But, I bought this 6 months ago. It should be a defect. Your suggestions should be valid to use the phone for years without problem.

Not exactly, I remember a member of the SGS2 forum uploading photos of he's screen after using something called coyote, some sord of car navigation, after regular daily use for a couple weeks it had caused noticeable wear in his screen.
Static images are bad for these screens if you have a lot of screen on time, the most affected will be your statuary because it's almost always off (black) so it'll be brighter than the rest.

Everyday 1-2 hours I am on Google Reader and Browser with white background. But, I still think that screen should be defective to wear off in 6 months.
Currently, I use black background
I think it should be under warranty. When I am not lazy or screen gets worse, I will format my phone to original ROM. Then, go to samsung.
I got the same burn in on my Nexus. Just returned it for repair. Reading about all these problems with super amoled screens makes me wanna change for a other phone since it seems to be a common problem.
If a screen replacement doesn't fix it permanently, i hope I can get an other brand without amoled. Just not okay to have these kind of defects.
Hey guys,
This thread is not about the camera taking photos with banding lines, instead about the actual display.
Does anyone have vertical banding lines most notorious when displaying a full grey screen in low brightness.
I've read the verge review and seems to have some banding as well, anyone as well? Thinking about replacing it for a third time.

You can't take a screenshot to see the problem. Its a hardware issue therefore you can only use an externeal photo of the screen. Check on grey full color screen. I think I will not replace it, I may risk on another issue..

Yeah, I had not planned on replacing mine either. I so infrequently see it, and even when I do, it really does not impact anything. I was not aware it was a hardware issue, seems there could be a bug fix for problem then.

Its funny cause the band shows up in the screen shot on my phone, but probably because the conditions are right, not cause its actually in the pic.
Vertical lines are something you should replace your phone for. Horizontal lines like in the screenshot is just the banding of the colors and happens on every single stock android phone because it's apart of the software

Could u check through a full grey background whether ur greyd are fully consistente? I mean there no faint lines whatsoever. Perhaps ur phone is the same as mine and u have not realized it given that it seems to be fairly normal with amoled displays
I was just about to post about this very issue. I created a quick image to show everyone what the issue is. The lines are not as drastic as I made them look, but it should give you the idea of what it looks like on the screen.

No. That is not the issue we are speaking about. The issue we are referring to is VERTICAL and only appears on greyish/black screens, like the settings screen. The horizontal lines are normal for this phone.

Precisely. You can't really use self screenshots to see this problem I'm talking about. Its about the amoled itself having these vertical banding lines(canvas-like strokes). Open Facebook and tap the search button and tap on the search bar without actually writing any name. Tap down the keyboard. For me the deep blue background has the most prominent banding lines for me. I have one week to think whether I should replace it. If everybody actually have these lines and NOT a solid color on full greys or deep blue I won't replace it.
PS. TheVerge moto x review says that it also have some banding lines on grays. I'd be great if you guys could check ur screens like I just explained. Hope I explain it well
Damn amoled!
Someone with the problem should post a sample pic/screen shot so others can download it and attempt to see the problem.
Just download a color test app that makes ur whole screen of a determined color. Put it on grey and check whether ur whole Grey screen doesn't have any vertical line banding. In case it doesn't have any of these lines, please let me know.
If it does have banding, take a screenshot and see it on ur computer monitor and see how the Grey should be displayed(full solid grey without lines)
I don't care enough to install an app, checking out a screen shot is quick and easy.
Took a photo with my tablet. These are the lines im talking about.
Also use the screenshot so u can check whether u have the same problem.
With the screen shot downloaded and displayed on my Moto X I can detect no banding of any kind. I tried it in dim and bright light. Screen brightness is set to auto so it did adjust with ambient light. Maybe I would see it if I manually cranked brightness to max.

Thank you, so my case is a defect, a third replacement will happen I guess. Great phone nevertheless.
It is possible it is something that was fixed going from 4.2.2 to 4.4.x, seems unlikely though. I notice you are on 4.2.2. I am on 4.4.2.
Impossible, my issue is definetively not software related but hardware related. When I see this screen shot on an LCD based device like my PC monitor, no banding is present. After all the pointless investigation this issue is sometimes present on amoled devices like the galaxy nexus.
