well looks like this did not fix my screen flicker and seems to be more of a hardware issue.
I'd return it. I haven't had any flickering whatsoever

Yea I would return it especially since they have stock now. Only problem I see is my auto brightness and brightness slider not working. I hope this is a software issue I think it is cause its effecting n7 and n10 after the 4.2 update. The 4.2.1 didn't fix this for me.

I had screen flicker, then I turned off the automatic screen brightness and set it manually and it doesn't flicker anymore. Maybe the same issue?
Any video showing what a screen flicker is?
[ISSUES] Nexus 4 screen flicker
Not exactly sure why you thought you needed to create an entirely new thread to update us on this issue.

I played with my NC nearly one week and I like it. But I want to know dose anyone notice the screen of NC is flickering. If you couldn't understand what I mean, please refer to below video,
http://www.youtube.com/watch?v=iDnBSWF44rM
it is not so obvious in real world as in video, but it is noticeable and uncomfortable. I have ipad with IPS LCD but never find this kind of issue. It like some kind of low fresh rate issue in early PC screen, so I want to know whether it is possible to fix it via adjust screen refresh rate in OS level.
Your comments are welcome!
Mine does that but only on the gray background, otherwise I don't see any flickering.
I exchanged my first NC because of this issue. The salespeople thought I was nuts until I demonstrated it for them. My new one still does it but MUCH more faintly and not all the time. I do believe that Barnes & Noble is aware of it (or at least that's something I read in another thread here somewhere..).
It seems to only happen at middling levels of brightness. My first NC exhibited the issue under very specific settings and times, the brightness had to be set between 20%-40% and I had to be displaying a solid area of mid-range colors. I saw it all the time when the screen would dim to display a menu.
From personal experience, you MIGHT be able to get a unit that's better if you exchange. It does seem to be a very common issue, though. Rumor has it that it might be fixable through a firmware update.. we shall see.
I had a pocket pc with this problem many moons ago...The fix was to adjust a trim pot on the display...
No idea if anything like that would apply here, but just wanted to mention it.
I do have similar problem, could any people advise on how to check the refresh rate and increase it?
Many thanks.
Are you planning on rooting or installing another ROM on your Nook? The overclock kernels fix this issue.
from what I see there in the video, if that is what you are seeing...not refresh rate. Rather it looks like a cycling in the backligt control. Almost looks like the PWM duty cycle is out of wack...would explain why it happens at mid range of the brightness.
My first nook color had this problem, I solved it by leaving the brightness up all the time which seemed to prevent it. I got it replaced for other display issues, and my new one doesn't flicker at any brightness, so yeah it sounds like a defect.
Not a defect. It's a problem with stupid coding in the backlight driver.
They set the PWM (pulse width modulation) rate too low, at 40Hz if I remember right. It's easy to fix by setting it up to 60Hz in the driver, which I did in my old Quickie kernel. Totally gets rid of the flicker, and I've seen no side-effects, nor have any been reported to me.
I don't have the time to keep up with the kernel anymore, and for some reason no other kernel dev has pulled my driver fix into theirs. You might talk to Dalingrin or one of the other devs if you really want it, and put them in contact with me at [email protected] and I can help them get it integrated into their kernel.
Can you link to the github commit?

Hmmmm.... my Nook definitely had the flicker issue on most gray colors, especially at dimmer brightness settings. I'm not using your kernel, but I am using Dalingrin's. I haven't seen flicker in months. Could this issue be limited to the stock ROM only?

It appears that way from my experience. I was running the dual boot package with stock and CM7 nightly.
The stock rom flickered very noticeably on greyish type backgrounds. Using CM7 and now Phiremod, the flickering has totally gone away.
Actually the fix is already in init.encore.rc:
Code:
write /sys/devices/omapdss/display0/timings 68000,1024/70/200/40,600/10/11/10
That said, it's going into the driver too.
I think I might have a software fix for the Nexus 7 screen flicker.
Screen flickers in low brightness and when using WiFi.
To solve this I am using an app called Screen Filter.
https://play.google.com/store/apps/details?id=com.haxor[/url]
When I want to dim the screen I first turn the brightness UP and then use screen filter to lower it back to the level I actually want to use. This gives me a dim screen, and I have not notices any flickering when hitting WiFi. Does this work for anyone else?
This does only mask the problem for those that has it. It does not actually solve the problem. It has been covered multiple times in other threads.

I had what I would consider serious flicker and using Lux immediately and completely eliminated the problem.
My nexus 7 has an issue where the screen randomly seems really washed out with a super high white balance. Then it will return to normal for no apparent reason at all during use. I'm on stock 4.2 nonrooted for the moment. I'm thinking its software related but don't want to root rom this thing if it needs to be exchanged. Turning off auto brightness hasn't helped. Maybe all the nexus 7 have bad color reproduction?

NVidia Prism Technology. Google it.
I love the phone but I've noticed that while navigating the phone the brightness flickers or pulsates somewhat. It's also noticeable when watching video. Also I've noticed when I swipe from blinkfeed to my main home screen I can tell the screen gets slightly dimmer.
It doesn't seem as pronounced when I disable auto-brightness but it still seems to happen.
Just wondering if anyone else has noticed this.
I also have but I can't consistently recreate the issue so I havent tried to get a replacement yet
Sent from my HTCONE using xda app-developers app
After messing around with the phone more it seems to me like the brightness adjusts depending on what is on the screen, like if I launch an app the brightness might change but once it does it seems consistent until I do something else. I don't know if it's trying to adjust dynamically based on what's being displayed or what.
Not really sure if it bothers me enough to do anything about it.
I had like a wave go through my screen while using the cam odd anyone notice the lines in the screen when its off ?

I haven't noticed that.
I actually went to Best Buy over the weekend and exchanged my phone to see if a different one would be better about the brightness adjusting constantly. My new phone seems about the same but I think I'm kind of getting used to it, also I just don't feel bad knowing that it seems to be widespread.
My phone keeps turning brightness way down by itself with this message. All temperature readings are fine. Any ideas?
-- Note III, TapaTalk II, AT&T is Horrible--

I too am having the same issue, however i believe that my issues is slightly different from yours. I noticed maybe about 2 days after i purchased the phone that mostly anytime I am using the browser, whether it be Chrome or the stock browser my screen automatically adjusts itself. I went into settings and made sure that the brightness was not set at "Auto" and turned all the way up. I also made sure that reading mode, auto adjust screen tone, and color adjustment were all turned off. I also changed the screen mode to dynamic and I seem to still have this same issue. I read on another forum for T-Mobile users that there are a lot of consumers experiencing this same issue, not sure if carriers are doing swap outs for the phones as this may not be related to a HW issue but rather a SW issue.
That sounds exactly like what I'm experiencing. Except I work outside, so when it does this it's impossible to see my phone. If you get a chance the next time this happens can you go into settings and open the brightness slider to see if you also can get this error message to appear? That seems to be the only place I find the message, it doesn't just pop up or anything. I too have checked like 10 times to make sure all the other display settings are correct, like automatically adjust tone and such. It sucks that auto brightness cannot be fine tune with the slider like it could on the note 2. I'm finding it very strange that instead of adding to features of the Note 2 to make this phone better in every area they chose to remove some great features leaving me wishing I did not upgrade.

It sounds like thermal throttling. LG phones have this, in particular the Optimus G and G Pro. I haven't had the problem on my G2 yet. It's designed to lower the brightness and lower the cpu speed in order to keep the phone from overheating.

True my LG Optimus G pro does this but there is a way to turn it off in the system menu accessible from the dialer. I have turned mine off and the phone no longer does this and has not gotten hot or anything. Wish there was a way to do this on the samsung as my S4 exhibits this same behavior.
I'm thinking about getting a Note 3 today so I'm hoping can be shut off too. I shut it off on my G Pro and the G2 doesn't do it, which I'm very thankful for since I work outside as well.

Since we're on this subject, how often does it happen on the Samsungs? I would figure less often due to amoled not being as bright as LCD.

You may be better served to leave the auto brightness checked when your working outside. When on auto, it gets much brighter when needed than with the brightness slider cranked all the way up.

Note 3 automatic brightness settings problems
I have a Samsung Note 3 phone bought in Germany. I have the some strange problems with brightness settings too. Typically from time to time the phone screen just get too dark. Particular in economic mode the phone can get from time to time very dark and even setting auto brightness to +5 does not help.
I was using before both Iphone 5 and the first Samsung Note and some other phones and automatic brightness control was always working fine. In my new Note 3 the brightness is jumping sometimes suddenly.
JVogle: You can adjust the automatic brightness by pulling slider up or down. It can by set from -5 to +5. But in my case this thing do not help so much. Particularly this is a bigger problem again in economic mode.
This is rather a software issue, because when I switch to manual brightness it stays constant all the time.
Anybody knows how to cure it?
This is so annoying. Gotta wonder if it's a bug in one of Samsungs ****ty features causing it to happen so much. Even without brightness all the way up it happens

You have a different phone than me apparently. Also a different issue, as I'm referring ONLY to manual screen brightness setting. I would expect fluctuations with auto brightness. I've never had a device fluctuate when manually set to a desired % though. I also can't believe they removed the ability to adjust slider with auto brightness. Sadly the only thing better about this phone than my Note2 is the specs. The software and user experience has been sub Note2 for me in every aspect. I will most likely be switching back to the Note2.

brightness issue
I have tmobile and I've had my phone for about a month and now I notice when it's in standby and I hit the power button to wake the phone the screen is really dim for about 10 seconds or so and then it brightens up. My brightness is on max and the auto brightness is disab
