I have installed Paranoid Android on my Note and noticed that there is severe clipping in the CM9 UI elements. Even the default ICS wallpaper , the one with the"rainbow" coloing stripes show severe clipping on the lockscreen. It looks just plain ugly. And since most of the CM9 UI backgrounds are a shade of grey, there is severe clipping of these grey elements to a purplish pixellation and to black. You can notice this if you take the settings page in Paranoid android or any other CM9 based ROM (assuming most CM9 based ROMS have the same default theme) Look under the status bar where the grey background fades to black and you may notice severe pixellation like issues at that area. Now, go to advanced, screen settings and MDNIE mode, you will notice that the clipping keeps changing when changing modes but its still there in every screen mode.
How many of you are experiencing this? Assuming a majority of the people who run Custom ROMS run a CM9 based ROM, why isnt this issue reported anywhere? I'm asking because, the issue is plainly visible in these grey areas and UI elements making the visual experience really bad. And why is Gamma Control disabled in these CM9 kernels? I believe lowering the gamma would solve the problem.
I've noticed that CM9 kernels have the worst clipping whereas in other stock based kernels, the clipping is comparitively lower, closer to the stock kernels.
So once again users of CM9, please do report if you face this issue.
CM9 users please report back because I havent seen anybody talking about this issue in any of the CM9 related ROMS thread. People seem to ignore an issue which stares back right at the face even in ambient lighting. Why havent this been reported?
I dont have much idea about who develops CM9 kernels for the note. How can we contact the CM9 developers and let them know of this issue and request to enable Gamma Control within the kernel?
Somebody please help me out here. Because its been a month after I bought my note and I've been struggling and doing my best to find a solution to this horrible clipping. I had got in touch with GSMArena and got this issue published, yet Samsung never responded, I tried kernel after kernel and realised that the intensity of the issue varies from kernel to kernel. I've seen that whomever I ask about the clipping in this forum says they have it but then everyone seems to be happy running different ROMS and in these CM9 based ROMs which look as close to stock Google ICS UI have severe clipping all over the UI and yet people dont seem to bother.
So what can I conclude from this? Is this an isolated issue or are all of you Note users who have this issue just keeping silent and living with it?
I do not mean to spoil anybody's peace or anything. I clearly dont know how to get in touch with the CM9 devs for the Note, somebody help me if possible. And if you feel that this is an isolated issue, do let me know otherwise. Because, when the basic UI shows severe clipping, the whole user experience is spoiled and nobody wants to live in fear with bright UI elements and bright wallpapers dreading the clipping if anything at all has to be dark. We paid a premium for this device and even Samsung seems to ignore. I have the SGS3 and there is no clipping on it but just that everything seems darker on the GS3 when compared to the Note. This alone shows that Gamma is a culprit here and I could just sell away my Note and just live with the GS3. But that doesn't help anybody who is facing this issue and wants to see a solution. Even I personally like the note more than the GS3 and I want to keep it but for this issue. Not everybody has the money to jump to the next flagship every now and then and for the people who spent their money on the Note doesn't have to "live with it" just because they decided to buy it without knowing such an issue existed. Not every store lets you try and trial their devices before buying them.
Samsung has even seemed to ignore the EMMC issue even after claiming they are "working on it" I dont see anything productive from Samsung's side as even a device which was previously unaffected had the affected kernels pushed to it via an update. So basically if it was not for people like Entropy who works day and night for that issue, Samsung could keep replacing motherboards for every random wipe a user does. They basically want to sell the note until the Note 2 and then this wouldn't be their problem anymore. Problems like the emmc bug is a MISTAKE from Samsung's part and they should be ready to repair devices even beyond warranty as the user may have only done the most harmless thing, i.e to reset the device to factory settings.
So, coming back to topic, how do we get in touch with the CM9 devs and enable gamma control on these ROMs? Most ROMS have gamma control under MDNIE settings which is greyed out, most probably because the kernel doesnt support it. This is the best I can do for the people who are affected by the clipping issue as I'm not a developer. This issue isnt an isolated case in my opinion and affects every Note I've got a chance to see.
It might help if you actually posted requests in the cm9 discussion thread? #commonsense
Seriously after reading TS long posts still*cannot figure out his problem
please post shots to show your issues
I have been using CM9 roms since build 2 and do not seem to notice such issues or maybe i am blind ?

Yeah. OP is TL;DR complaining about some "severe" issue I've never seen and no one else has.
As to gamma control being disabled - I should remove that from the settings app, as that's something supported by the I9100/I777 display driver but not ours.

Oops..I'm sorry for the long post. Its basically about the severe "black clipping" which has been affecting the Note since release. This issue is best seen when displaying dark shadows in images and videos. There were many threads discussing this issue. And GSMArena had published this issue in their news after I mailed them about the same.
What I wanted to tell was, I feel this is caused by the Note's screen having the gamma cranked up quite high and I believe lowering the gamma would resolve this issue.
The default CM9 theme shows severe clipping in backgrounds and UI elements. All the grey backgrounds, (the default theme) clip to black just below the status bar.
Even all the videos which have dark shadows are totally blocky due to this and the clipping makes them literally unwatchable.
I had reported this issue to GSMArena
http://www.gsmarena.com/samsung_galaxy_note_plagued_by_display_issues-news-4513.php
I wanted the Gamma Control feature which is presently disabled to be enabled in the CM9 kernels so that we can tune down the Gamma to eliminate this clipping
The same issues existed on the GNexus and was fixed with the Lean Kernel which had Gamma Tuning.
So once again, in short, I'm talking about the "Black clipping\crush" on the Note when displaying darker shades of colours.
All the notes have this problem, and we need to access to gamma control but as supercurio said it won't solve all the problems of the black clipping and banding issues

Satishp, i know what are you talking about. Just take a picture of your note and post it here. Of course, you won't use a screenshot feature but a camera.
I sold my note bc of the black clipping issue, but now I cannot buy an s3 or HoX cause their screens are just to small, that is, narrow. Gonna buy Note again and hope some solution will come out. It is too bad to buy a phone for its screen and get a crappy quality. Issue on s3 is solved with lowered gamma. Comparing with the Note, s3 has much darker screen. Sometimes too much.

Everytime I turn my screen on I smile at how awesome it is..Hell it seems even better now that I have been using cm10 but i think thats just because its brightness seems to be overall set higher.

All of the speculation and misinformation of this issue is really starting to get frustrating. First, the issue IS with the hardware. It may be possible to reduce it's impact using software but the fact remains this is a hardware issue. How do I know? I have replaced my Note's screen and the newer screen I have isn't as good as the old one.
The new one isn't awful, it simply isn't as good as the other.
2nd point - everyone will have this issue. It is simply an inherent problem with the screen hardware and it is completely implausible that there are 1 or 2 'perfect' screens out there. There will simply be variations. Some people WILL have better screens than others. For some people the issue may be completely unnoticeable and for others it will be glaringly obvious. Don't judge or hate on people because their screen is worse than yours and vice versa.
3rd the issue is MORE noticeable at lower brightness values than high brightness values. If you have your note on higher brightness values then you're unlikely to notice it. In my case, I can not see any clipping if I am in a lit room. The only time I can see it is when I'm sat in the dark with very low brightness. As I said above this will vary from person to person.
I have attached 2 photos below. One is a normal exposure where you can see the clipping is hard to see. Another is a long exposure which amplifies the issue more and makes it more noticeable (I used a longer exposure on my camera to show this). Fortunately it isn't so bad for me, but for some people my long exposure image is the reality unfortunately.
Standard: http://i48.tinypic.com/4uxnia.jpg
Long Exposure: http://i48.tinypic.com/5akew3.jpg
Why have we got a clipping problem and can software solve it? I believe it is highly unlikely that this issue can be solvable. I also think the issue stems from one simple shortcoming to the screen; the minimum brightness achievable per pixel. The problem is the jump from this minimum brightness to the 'off' (perfectly black) pixel is too great. There is no transition. Can gamma control solve this? I'm not convinced. I think the issue is more to do with what the lowest pixel brightness the screen is capable of. For the poorer people this minimum brightness will be quite bright. For others the minimum brightness will be lower.
If any devs know of a way of controlling pixel brightness on a level where it can be noticeably changed and if it is possible to reduce this minimum brightness then sure, it would certainly be a possibility. But I don't think this is possible.
Part of this might be a limitation of the HD Pentile AMOLED technology. But if you notice, both the Galaxy Nexus and the Galaxy S3 share the same technology. For people who argue that the S3 uses a different manufacturing procedure, Samsung has no where mentioned this and its just an assumption.
The GNexus had the same issue but was solved with the LEAN kernel which implemented a gamma control within the kernel. If you've seen the S3's screen ( I own an S3 too, So I've spent a good time comparing), you will notice that the S3's screen is visibly darker than the Note's screen. Images tend to look darker and this shows that the S3's screen has its gamma set to a lower value which eliminates the clipping.
More proof for you, lets take the gammatest image and view it on our PC. Most PCs use an LCD display and still you can see the greys gradually fading to black.
Now increase the gamma of your display from your display adapter's color settings and view the same image again. You will see that you can see all the way upto 1 and then black just like how the image is displayed by the note.
http://forum.xda-developers.com/showthread.php?t=1800117
Now view a 720p or 1080p clip on your PC with the gamma values still high, you will see the clipping in every dark scene. Try it yourself.
This shows that gamma calibration can correct the issue to atleast some extent.
Hmm. There appears to be truth in what you say. Unfortunately the Note is lacking somewhat in the developer department. And the few devs there are have other pressing issues to deal with so the question becomes who can implement gamma control on the Note?

Yup. Despite being pentile, compared to my I9100/I777 the screen is even more gorgeous.
I'm on minimum brightness nearly all the time. No clipping issues whatsoever.

I have the clipping regardless of which mode I put it in, apart from the clipping the screen is mint, which makes me even more pissed off when I watch a movie and a dark scene comes on, then the shade between black and grey turns into a lego block mess. I really cant beleive so many people are happy with it, half of u guys must be blind, I exchanged my Note twice, tested my cousins and my bosses Notes, all have the exact same problem. I even bluetoothed the gamma test image to a few in carphone warehouse , same with them, even the samsung rep I spoke to over the phone said the one they have in the office also has the issue. Total crap imo, Samsung total FAIL.

Please take a picture if your note displaying the gamma test image (blocks numbered 1 to 20) with stock gallery app in a dark room, screen mode dynamic, max brightnes with auto adjust switched off, I bet number 4 is light grey, then number 3 is black, if so your device has black clipping. There should be no abrupt drop from grey to black, it should be a gentle fade.
Thanks.
I got my Galaxy S4 yesterday and noticed even after i turned auto brightness off, Set my screen to dynamic, the screen still changes brightness levels when entering the Chrome web browser (gets dimmer), playing some video games (screen get brighter) and other various tasks.
I am not a noob, I've gone through the phones settings for each app and cannot find a fix, do you guys notice your phones doing the same thing?? I might be a slight change in brightness level but non the less i like my screen extremely bright this is just my preference.
Any thoughts, ideas, tweaks or feedback on how to resolve this issue??

The only time I've seen this happen since I've gotten the device is when the battery dropped below 5%, and it automatically adjusted the brightness to seemingly the lowest it could go, and stuck until I charged it to full again.
I blame it on Samsung's stockware.
maybe this is why i couldnt get the phone to look as bright as my note 2. i was using the browser and cnn.com to compare.. my note 2 screen was brighter with both phones brightness on max.

Just throwing this out there...the screen does dim about 10 seconds before the screen times out and turns off...even if you have automatic brightness disabled.
Let's say you have a 1 minute timeout:
Screen on
50 seconds later screen dims
10 seconds later screen turns off
Just putting that out there in case - it is confusing to some.
Dude I'm having the same problem, yeah it's a small dim but it's freaking annoying cuz I have mine at full brightness all the time. I have the tmobile galaxy s4. I tried changing the screen mode and it still happens

I've noticed it too. Just seems like typical dynamic contrast behavior. Though I don't understand why on earth you'd need it on a screen with perfect blacks.

I'm sure it has to do with preventing burn in. You probably already know this, but in the right conditions, the Auto brightness setting can get over 30% brighter than manually maxing the slider. Hopefully, it's something that can be unlocked at some point.

Its the power saving option. Its the same in s3. Go to powrr saving settjngs and uncheck the auto dim or auto brightness or something like that. It happens when power saving is on. I cant remember the exact optin coz im using custom rom on my s3.

This happened in the S4s I used in the store as well. Manual brightness, and auto screen adjust disabled, power save off. Opening certain apps like chrome and the stock browser causes the screen to dim a bit. Nothing I found prevented this behavior. It's annoying since I already find the screen to be a bit dim.

Notice this as well, super annoying. I've disabled power saving, auto screen adjust, etc. and even non-dynamic modes do it.
Hopefully this gets fixed by kernel mods in the future
Same problem, even with brightness max with auto off, decent charge, and off power saver. Very annoying

Its built into the Snapdragon, its called BRITE and seems works independantly of the auto screen tuning that the S4 has. The HTC One has it and its much more intrusive. I wrote a long winded post about it in the HTC One forums. You have to wait for devs to come out with kernels to disable it, much like they did for the Tegra 3
The HTC screen is bright enough that it doesn't matter. Samsung phones need to be at max brightness to be any good.

Just an FYI, if you put the screen on auto brightness, it reaches a higher maximum brightness outdoors as apposed to the slider. Samsung did this to keep the screen from overheating when set to max all the time.
I want full brightness indoors too.

I see. If you have the slider on max all the time, i think the screen will just dim eventually because of heat. Might want to stay away from the S4 then cus you might have screen problems down the line :/
If you havent go to settings display screen mode and use something other than adapt display. No more adjusting.

I got my GPE yesterday and while setting it up, I noticed that the brightness would change on its own intermittently from the same bright white that I have on the LGE I picked up last weekend to something like what folks are describing as the more yellow-tinted display on other threads. Note that I do *not* have auto-brightness enabled! This is happening when I have the brightness cranked all the way up to 100% without auto-brightness.
If the screen were yellow-tinted all the time, I'd think it's the same issue others are reporting, but since it does vary between the two randomly, I'm thinking/hoping that it's software and not a hardware issue. Does this sound familiar to anyone else? If so, does anyone know of a way to lock it in on the brighter/whiter setting?
My GPE is doing the same. Brightness will either dim or brighten on its own. It's a very subtle change, but definitely noticeable. Also its very intermittent and I've only noticed it in chrome, Google now. I also have auto brightness disabled and brightness at or near 100%.

Exact same experience here. My Galaxy S4 does something similar. I found one thread the other day saying that Android lowers the brightness automatically when the device temperature hits a certain level (95F, maybe?). I've never seen this on my other Android devices, but I'm kind of resigned to this being the case. It's really my only nit with an otherwise outstanding device, so I guess I'll live with it.
Some of you may have noticed it's difficult to watch dark scenes in movies on the gpad. I think the problem is the gamma calibration, you can see it clearly on the pictures I took.

On the top you can see my nexus 7 2013, you can differentiate all the shades of grey from 1% white to 100%.
On the gpad, everything is solid black from 1% to 12% of white.

How low can you go, on your gpad, before the grey melts with the black ?
Do you know an app to apply gamma correction ?

I see the difference, and I knew it was there already also.. I'm sorry, but apparently gamma is not something that is doable. - I was looking to link you the app from market called "Screen Adjuster", however you want to look at this description, especially the last sentence. ;/
- dimming the screen 15-100% (below minimum system brightness)
- screen color and a contrast adjustment
- system brightness 0-100% adjustment
- functional widget (on/off, system brightness, settings)
- autorun option
Some phones have a color tint screen. This app have a possibility to try to improve colors on this kind of the screen by setting an additional factor RGB.*
The range of the dimmer is from 15% to 100% (it allows to dim the screen below a min system brightness value). Make a relief for your eyes during a nightly reading.
Furthermore, you can change fast the system brightness too.
The additional contrast factor can try to make the reading or a picture viewing more comfortable on some screens.*
The widget provides fast on/off service with a shortcuts to the Adjuster settings and the system brightness settings.
The application has the autorun option which works with the dimmer set above 22% (for the safety).
Note
A gamma adjustment is not possible to do.
You can of course try and download the app anyways and see if contrast or brightness will do anything for ya.
- In case you do download the app, remember that setting contrast low will result in problems with installing apps, as in you cannot hit Install, only cancel. To avoid this, open up Screen Adjuster and turn it off, install the app and turn it back on afterwards. It's something about lowering the settings to lower than what is "intended", I don't quite understand it and I find it rather odd. But it let's you install apps.. So I guess hooray.
That's all I got.

Thank you for your response, but I'm already using screen adjuster. I set the contrast at -25 and it helps a lot to see dark details.
Unfortunately, it has two side effects :
- it brightens the dark shades of grey, but also the black levels.
- I noticed that the contrast setting also affects the white making it look like light grey.
So the contrast setting in screen adjuster doesn't affects only the dark tones like it would on a monitor or a tv, it affects the contrast ratio.
I've found apps to make gamma adustment but it only works on some devices with custom kernel.

Yea, I was about to say that gamma can be done but only on custom kernels. Lot of Nexus 5 stuff on the market. Apparently it's Google who locked the gamma settings completely down but only in 4.4.2. I guess it may work on stock LG Kernel since it's only 4.2.2? I'm afraid we'll have to wait for some kernel support for other roms. That would be awesome. I really hope for some Franco-kernel-glory on this device.
That's what I thought, we need to wait for custom kernels...I hope it will come soon, because it's so frustrating to have such a good screen with bad calibration !
People tends to complain too much about the warm white balance but the gamma calibration is far more concerning.

Hi there Young Bobbie, I am new to posting on XDA so I couldn't post this in your kernel developer page. This is my first post on any forum page ever. First off, thank you very much for your hard work to make this kernel happen to correct gamma on the v500. I have been sitting on the fence whether to get the gpad, and if i would get the v500 or the v510. Was leaning toward the v510 because of Sleekmason's wonderful kernel work, but it's exciting that we have now have the same options available for the v500. I noticed this was working fully with the Malladus ROM. My question to you was whether or not this worked with stock LG ROM as well? Thank you again YoungBobbie and Sleekmason for your time and creations.
Sorry, just answered my own question. Guess it helps to read the very first line of the page (making fun of myself now ;-P) Thank you again YoungBobbie and sleekmason!!!

Be happy to. Have to acquire the device first, which will be in a matter of a week or 2
Im using a att s6 edge+. seems with auto brightness off the phone still changes brightness in a dark room. im coming from a note 4 and this never happened. i did read alot of issues like this on the smaller s6 edge. some people said to download lux or other brightness control apps but none of these have helped. I have also changed to each different display option to no avail. i tried with my flashlight while in a room and the phone did change brightness. also to note.... even the light coming off my tv was enough to change the intensity of the phones brightness. did i get a defective phone. there hasn't been a fix and searching online for this new phone has been pretty difficult. any advice would be great. my personal preference has always been to have the screen on max brightness but that's a personal choice.

Would also love a way to fix this, it's incredibly annoying, i cant stand it... I've also tried several "fixes" none have helped.
sucks because the only time i ever get full brightness is when im in a room with ALOT of light. only then will the screen go to full brightness.
Same Issue
Has there ever been any type of resolution to this? My phone does this as well. Don't want to return it for a refurbished Verizon phone that has a high change of also having the same problem. Don't want to root and lose Samsung capabilities and void the warranty. Just had a software update TODAY, this very morning and it didn't fix it. Call Samsung and they play stupid and act like they've never heard of it. This isn't a big deal in the grand scheme of things but at the end of the day when I'm trying to read at night or just browse the web and I have my bedroom lights off, I want my screen to be vivid and bright, but I get dull and dim.

What discourages me the most is that I just got this phone about 2 weeks ago and noticed this within the first few days. I google this problem and I see threads being posted about this mostly starting in April of 2015. We're now in late October and this is still going on, which leads me to believe Samsung is just not acknowledging the issue at all. I'm tempted to root just to fix this, but don't want to void the warranty and lose Samsung features like the edge notifications and clock.

Have you tried going into settings > Display > Screen Mode and switching off/changing from Adaptive display? Adaptive display is the default setting and this also messes with your brightness and colors dependent on your ambient lighting.
This is a well known bug on most S6's - Looks like a Firmware update should fix this issue.
Turn auto brightness off and set to max brightness ,then hold the phone to a bright light you will see the brightness dim after a few seconds, +BUG+

It's a feature, not a bug. I doubt they'll fix it.

Ok so I went to the link you guys posted about the fix for this on the S6 edge. 1st off I get that it's for the edge not the edge + but could someone explain that fix in English? I didn't understand a dam word of it. Do you have to be rooted to do that? I'm hoping they fix it for the edge + soon, very annoying bug....
