[Q] My Super amoled is not that super anymore?

When i bought my galaxy i was very impressed from its colorfull screen and especially it's black color.
Now after 1.5 years i think that my screen isn't that cool.As for the black colors when i see an image with different shades there are some strange colors like grey or "pixeled" colors.I don't know if you understand what is my problem but i want to fix it somehow.I tried voodoo color but the same thing happenes.Only if i reduse the
colors from voodoo control the screen gets better but then i have no brightness...Any help or settings about this?I have used many roms including gb(cm7) and ics(simply ,icssgs,and aokp) and many kernels and i have always the same problem.

Screen burn-in . Happens if your brightness is too high, or a pixel shows the same color for a longer time. Normal after 1.5 years.

Not sure, my screen had a problem displaying greys until I started using voodoo color and set it up correctly.
Try these voodoo color settings, it's bright even on low brightness settings.

If it still has the same problem you might have to take your phone to Samsung for repairs. Does it still have warranty?

My waranty is over.As for the burn in thing i ve tried the phone test with the code *#*#0*#*#* and nothing happens..dunno why maybe this code doesn't run on ics can someone tell me if it works at his phone?

I don't think you have burn in from what you said in the op. Install a dead pixel test app from the play store if you want to look for burn in anyway.

CM9 devs and users attention please! Severe clipping in CM9 based ROMS

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.

Galaxy s4 screen throttling

Anyone notice throttling on the screen in terms of contrast tone and brightness. You cannot turn it off no matter what settings you choose. One good example is when you pull up the keyboard and the brightness is fairly low, there's a huge color shift that pops up till the keyboard tray is gone again. Could a kernel fix this?

i am trying to get some help from international model guys on this; mine DOES NOT change contrast and brightness if i disable every auto feature AND ALL POWER SAVING features. I have seen this on another GS4 and not on my own or my GF's with everything disabled. I wonder if there is a difference in screens or part batches and sensitivity or a different controller chip; another thing im looking into.
also the ambient light sensor; try covering it completely. i think that and the 'auto detect/modify screen contrast/colors' is running no matter what on certain GS4's.

i have calibrated many monitors before; maybe when the bootloader is unlocked and there is a full ROM dump someone could assist me to find the screen calibration adjustments so i can create a professional AdobeRGB and sRGB profile for the screen as well as rec 709 full and 16-235 video modes etc. I am not the only one interested in this; the Galaxy S III, Note II, and Google Nexus 7 are all excellent candidates for field monitors with excellent gamut. I just want mine to display colors as accurately as is possible for the moment; i keep all my demo reel footage and music videos i shot on it; a proper 'flat' image is important before editing, and my company we shoot raw, yet even a simple 8 bit example of before/after editing in raw environment would help our clients.
This is the first mobile full HD screen capable of such broadcast range of gamut; would be incredible to use as proper field monitor with correct calibrations.

Gpad screen gamma is too low

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.
https://imageshack.com/i/nf96iaj
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.
You can find the original image here : http://imageshack.us/f/594/6291.png/
How low can you go, on your gpad, before the grey melts with the black ?
Do you know an app to apply gamma correction ?
Here you can see the same picture on the N7 and the gpad. You can't even distinguish the guy's ear on the g pad.

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

Notification LED RGB (proper) Calibration Reference

Hello everybody.
I have noticed that S7's notification led(s) have an inaccurate RGB colorspace calibration.
Some of the leds are stronger than the other (or their voltage is incorrect) resulting in weird/unexpected color combinations.
For example FFFFFF which should be white is instead a light Violet.
I'm leaving some properly calibrated values for anybody that might want to make a kernel with corrected notification RGB or atleast for the sake of having a reference.
White - 55FF44
Yellow - 66FF00
Orange - FFFF00 (in proper RGB this code represents Yellow!)
Cyan - 00FF55
Purple - 8800FF
Magenta - FF00AA
By the above combiantions you should be able to judge pure R, G, B values.
If someone wants to test the above colors grab a LED notifiction app tester and try the stock color code options which should represent proper RGB calibration and compare them to the ones I posted.
One of those apps is https://play.google.com/store/apps/details?id=com.coolbeans.ledtester
PS: That post might fit more to the development side of the subforum but I was reluctant to post it there.
If any of the mods feel that it fits better there feel free to move it.
PS2: The above values are by no means calibrated with a scientific method. There is a room of like +-08 for each R,G, and B value for proper tuning, which I guess is more than fair.

Same dude. And app does not work.
