[Q] Galaxy s4 screen fade - Galaxy S 4 Q&A, Help & Troubleshooting

Dear Sir or Madam!
I have Samsung galaxy S4 with Cyanogenmod 12 Nightly on. And a week ago after an update my screen faded. It hasn't been showing the typical vibrant amoled colours since. They are washed out and have a green tint which becomes much more noticeable when the screen gets dimmer. However on maximum brightness the colours suddenly shift back to normal vibrant and the difference is very obvious. I knew what I was putting myself into when I installed Nightlies, but I waited a week and none of the updates fixed the problem.
I really look forward to anyone helping me with this issue!
Your's sincerely,
ribicjaka

This isn't a proper fix ..get a app from play store like screen filter a bunch of them are available at play store ..so u can adjust RGB to ur desire...but as I mention its not a fix ...
sent from my GT I9505 5.0.1

thanks but it was fixed with an update

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.

Huh?
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.

Same. I don't often stare at my phone from a distance of 3cm to see any imperfections.

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.

[Q] 4.3: Did the update improve your phone's colour configuration?

The other day I was watching someone's YouTube video where they showed off the changes in Android 4.3 on their Nexus 4. I bought my Nexus 4 yesterday (running 4.2.2), but the colour configuration is terrible. Blacks look grey/olive green, and everything looks washed out. In the video, the guy said Google updated the colour settings for 4.3, and everything looks more vibrant and less washed out. For those with the 4.3 update, can you please confirm this?
Thanks.
I think I read that the values regarding colour are the same as in 4.2.2, so no change. Don't take my word for it though, maybe someone else can confirm?
Personally I didn't notice a difference between 4.2.2 and 4.3 stock colour either.

Auto brightness is off but screen still changes brightness

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.
---------- Post added at 12:52 PM ---------- Previous post was at 12:29 PM ----------
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+

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....

J7 Pro AOD problem

Hi everybody. Recently I bought a J7 pro for several reasons, one of which was Always on Display, a.k.a AOD. However from the first night I used it as a night clock I could apparently see that the background of the clock and notifications is not black and has a faint light. The funny part is that the preview of AOD is fine with all the black pixels off, but when you actually use it, all the pixels are on. I asked several J730F owners and they had the same problem, however my device is J730G. Please test and report. Just remember the environment must be completely dark.

Hey
I have the same problem
I have a j730f/D's
It's really frustrating and I guess it drains the battery a lot
I also noticed the that the preview of the aod is perfect on all brightness levels
Maybe thats because the display panel uses different settings when real aod is on ( like udervoltage and lower refresh rate things like this but I am not an expert )
Also visible on 3rd party apps from the PlayStore
I guess Samsung is using some hardware tweaks there to optimise battery life
What I also noticed is when the real aod is set to full brightness because of the sunlight the screen really gets black ( you can try this with a flashlight or so )
But on the lowest brightness the screen gets grey .
Would love to know if this is just software related or hardware
Because if it is hardware I give it a try and send it back

That's exactly my situation as well. On low brightness the screen is unbearably gray, otherwise it seems to be completely black. I guess you can try sending it back, unfortunately I don't have that option.
3rd party apps sucks because they can't use this special display mode Samsung uses
Maybe I will send it back
But I am not sure about that I wanted to wait until an update is coming, maybe it's software related so they can fix it .
I also send an email to Samsung but I saw your post on the Samsung forum so I don't expect too much
With how many ppl did you talk about that problem that have the j730f ? I mean it doesn't make sense to send it back and get a new one if it is a problem for every device
I got the same issue on my J730G/DS. When on low brightness aod, i can notice the whole screen lighting up a little bit. But on high brightness it is completely black. I think all j7 pro have this issue. At least we could try to send it back to samsung and see if they will fix or even do something about this issue.

Unfortunately we don't have a robust Samsung representative here and I believe we cannot convince them about this issue. I believe you guys should go for the guarantee. This way at least you raise the issue to their awareness in practice.
I have the same issue too.
I've chatted with samsung and ask them to try this but they keep saying "All of our units are fine".

I found several threads out there talking about this problem. Generally the problem was with S7 and other Samsung flagship devices. In all the circumstances there, the problem only was fixed by changing the AMOLED panel. However here in J7 pro it seems that when the screen is well lit, the black is truly black and when the ambient sensor reduces the light the problem shows its ugly face. This problem was not mentioned anywhere in those threads I mentioned.

I don't wanna waste any more money on my phone. So yeah let see what will Samsung do. It's impossible that this is the AMOLED panel fault. Looks like the version of our AOD is a bit old. Try compare it with the A 2017 Nougat AOD.

i tried atleast 3 different third party aod apps and all worked fine but only fault was battery consumption. so maybe it is not hardware problem. its just software related. we can only hope that samsung fixes it soon by update

Although I hope so and believe that j7 problem is different from previous problems seen on other faulty aods, but the way aod works is different from the way other aod apps work.
Hey guys
I've borrowed my friend's J7 Pro to see if she had this AOD problem. After I bring it to a very dark place, the AOD works like it should (No grayish AOD background). Guess it's a hardware problem. I will try to send it back to Samsung if I have time.

Have u tried it when the screen light adjusts to the dark environment? If so please do send it back to make sure what the source of the problem is.

The AOD uses the ambient light sensor to decide what brightness should be used ( I think AOD only recognize Dark and Bright situation, just like most of the proximity sensors )
So because it's dark, the screen also adjust itself to dark situation. No grayish background is seen. I compare mine with her side by side and I can see the difference.
Another thing to proof that this is a hardware problem is that when you put your finger on the fingerprint sensor and it unlocks, between the unlocking process, you can see the screen flicker before it unlocks the phone. Same as when you boot up the phone. Right after when you press the power button and it vibrate, you can see a flicker before "Samsung Galaxy J7 Pro" is shown.

Please do us all a huge favor and take some time and send the device to Samsung (I would if my phone was under warranty) so we can make sure what the root of the problem is and don't raise our hopes. :good:

I will find some time to send it back to Samsung. The distance from My home to the nearest Samsung Service Center is very far, took me about half an hour with usual traffic. But they are usually traffic jammed, so I predict an hour trip to the SSC. Not an easy job though I'm very busy all day.

Hey folks.
This Community works largely with US based devices so it's hard for us to speak on what may or may not have been in that update to cause this. You are welcome to see if the Community can assist, but as many may not have the same device as you it might also be worth reaching out to your region specifically for more in depth assistance!

I have this issue ever since I bough the phone in early August. Not 1 but 2 unit, model SM-J730G/DS. Both show the same symptom. Do Samsung selling phone with defect amoled panel or poor software implementation? What the hell!
If you all notice, the official samsung's AOD app for our J7 pro is not available anymore in Play Store. Why they remove support for our device? Why? From the feedback there, a lot of j7 pro owner report about this aod problem...

Jelly effect while scrolling

N986u1 unlocked version bought directly from samsung and I'm having a jelly like effect on black and darker colors while scrolling. However if I increase the brightness it goes away. Is anyone else noticing this?
in all apps or just some?
Wasn't that one of the display issues reported on Snapdragon variants on dark colors while at low brightness? Search for the "green tint display bug" and see if it's similar...
Sent from nowhere over the air...
I searched for the issue. There's no jelly effect mentioned and I'm not having the green tint effect at all. Just jelly at low brightness
I am having that issue too, but only when dark mode is one. So I just turned off dark mode for now. Seems to fix it, although there still is some effect when scrolling, its not as bad with the dark mode turned on.
Try disabling animations completely in Developer Options?
That's one of the first things I do anyway.

Did you restore a backup from another phone to your Note Ultra? If so a FDR should fix the issue. A lot of issues are being reported as bugs and they simply restored data from an old phone to the Note 20, not a good practice at all. Your new Note 20 should be set up from scratch.
Are you sure it's not oled black smearing? Can you record the issue you are having?
I get it on my Google feed quite often
