[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
I'm sure you can tell I'm not technical when it comes to these types of things :) I agree it does have a greyish overcast to the video but its definitely watch-able. I guess it's like a lcd screen with hat mode (Isn't that similar to the supercurio fix?). When you get used to deep blacks on an samoled screen I guess it's not the same. But it's much better than before. Samsung need to fix the issue though.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Yeah this is very similar to what supercurio has released so far but w/o the added dulling of colors that are not affected by the issue. But yeah it makes movies like underworld and other films with tons of dark scenes watchable.

The blacks on the SAMOLED does spoil the end user once they get accustomed to it, hence why blotches on blacks are even a problem these days!

EDIT:

Sorry if my post was offending you, I always try to explain what I know/understand on the issue so someone with better knowledge can correct me or for those who dont know yet may learn more.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
No offence taken.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] martcerv:
I see why your so upset about your screen that looks terrible, Im downloading that clip and will see how it looks on my gnote. Ive sold my gs2 now so cant compare but ive never seen anything look that bad on my screen.

I watched that video on my note and the banding is pretty bad so its a good video to highlight this software issue, using supercurio's app though pretty much eliminates the banding but makes the blacks more like backlit LCD greyish blacks. This shows its just a software issue though and if SC can manage to reuce banding whilst getting blacks to display like OLED blacks should then I will be very happy.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I like users like you the ones that actually try to test things out instead of mislead other people with their 'perfect' results.

If they can fully fix the issue then I can accept the horrible viewing angles on my note :D

Right now Im processing for a refund and I hope its gonna be approved, I'll keep my eye on this thread and just repurchase when they've manage to fix this issue.

No need to re-purchase- wait for Galaxy S3 this late spring or wait for Galaxy Note 2 in Late summer. still having problems with my display as well, samsung will probably leave me no choice but for refund as well, will be updated soon
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Unless the Galaxy S3 comes with like a 5.0" screen then I dont think it will be an option for me unless 99.99% of the screens are flawless then I would grab that instead of repurchasing a Galaxy Note.

hey guys plz let me know how to get the refund?? i already have replaced two notes and send the 3rd one for replacement but i'm quiet sure it'll have the same problem so i want a refund this time.Guys plz tell about the procedure to get the refund.:mad:
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] SAlmighty:
EarlZ, I don't think these screens are going to be perfect anytime soon. The SAMOLED technology seems like a work-in-progress. I'd give it another year then buy a mobile with this technology. OLED televisions are already being manufactured by Samsung. Hopefully the company can invest time in making quality mobile displays equivalent to that of a TV.

I can bet you, the S3 will be plagued with issues too, just like the S2. I would not get any hopes high for that.

Sure, be positive, but sometimes reality needs to tick in. Lol

---------- Post added at 03:59 AM ---------- Previous post was at 03:58 AM ----------

don't get your hopes high thinking that samsung will address these problems in subsequent models. we need to get their attention and make it clear that problems exist. samsung doesn't know what we know, if they do know, but not telling us, then that is just against the law, and they need to execute a global recall. perhaps there should a universal law like Magnuson–Moss Warranty Act, and if not applicable, have the world go against the samsung.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I dont put the entire blame on samsung about this but on the consumers that accept these issues as 'normal' but then again not everyone how gets the galaxy note uses it to watch videos nor does everyone have the same expectation.

It would be cool if companies start to use the Six Sigma

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
I agree Samsung need to be made aware of the issue. I am always writing on their Facebook wall to highlight the issue to others users but it seems no one else is. It's fine the issues are highlighted on these forums but that's as far as it goes. I think we should all post about the issue to all Samsung sites as well as email samsung.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] SAlmighty:
I think the blame is on both. Samsung is suppose have an obligation to provide support needed to satisfy their customers. Hardly they acknowledge the issues we post online.

I'm surprised to read about Motorola's promise. :eek:

BTW--I strongly doubt the S3 will have that big of a screen. I think it will be less than 5 inches, most likely between 4.65 and 5 inches, but not 5 inches to be exact :p

I have requested a feature on this on a well know gsm site. I have emailed them. Hopefully they will respond.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I hope that GSM site is not being provided by Samsung with review units, otherwise it wont get published due to the fear of getting black listed.

A picture posted in another forum where I shared about this issue.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
I posted a while ago that using movie mode improves the clipping enormously and now it is confirmed by indie.I don't know why this doesn't work with Earl's phone.

I believe the movie mode has the gamma curve set more correctly for darker videos but it can still be improved upon as there is still some clipping.

Using the app screen adjuster set at about 38 completely removes the clipping but blacks become greyer but I can accept that until Samsung fixes it.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Switching to movie mode some what improves the images and removes that awful violet banding but it does turn blacks into greys, on other handsets in standard mode they get a lot better result its like in movie mode but w/o the added glow on the blacks.

The image i posted above is with standard mode, doesnt look as awful as mine both in picture and in person.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
Ok, I have just done a comparison on my G Note. On the left is standard mode and on the right is movie mode. All done on 100% brightness and 100% brightness in the video app settings. The bottom one is also on Movie mode just to show that the problem does not go away.

I have looked at my friends note with the same file and his is only marginally better than mine but still is bad.

It actually looks slightly more worse in person than the pictures show
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I dont understand why it looks so awful on this new screen.. vs all that ive compared with.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] SAlmighty:
I wish I can take pictures of my screen, but I don't have a proper Camera. I find the replacement to be better in respect to the black clipping in normal viewing. However, holding the home button and bringing up the task manager makes the screen while a dark screen in a video is playing in the background, appear disastrous! :confused: :mad:
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Now that youve mentioned that can you open the gammatest imge in the gallery and bring up your ask switcher and see if the clipping goes all the way down to 8
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] SAlmighty:
Results

EarlZ, here are my results

Dynamic and Standard Modes: Numbers 1-3 are not visible on the left-side of the screen. Those numbers are more or less close to black. I can't see nor distinguish them in normal lighting conditions. I haven't tested this in a dark setting.

In Movie Mode: Numbers 1 & 2 are black, not visible, however, number's 3 and so on are visible.

Correct me if I'm wrong, the clipping (you're referring to black, right?) only goes up to '3' in Dynamic / Standard Mode and the clipping only goes up to '2' in Movie Mode

So what can we conclude from this display? :confused:

Is there an issue of black clipping in my display?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
I've seen 5 notes. All numbers can be seen until 3. When movie is selected 3 can be seen but not 2 onwards. I dont think its hardware but i know screens have a big part to play. Why is my friends black clipping slightly better than mine but still exists?

If you cannot see up to 3 on the gamma test than you have a faulty screen i guess.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] martcerv:
I know there seems to be a lot of screens that really shouldn't have passed QC and as earl says by people accepting hardware faults it just means samsung will set themselves lower standards of QC. If they get 20% of the substandard screens back it still means they managed to offload 80% that would have been all lost otherwise.

The yields must be very bad still if there is so many screens with varying issues.

Im lucky with mine as it has no real hardware issues, this makes it even more frustrating to me though when it looks like the software is holding it back from its true potential.

My gs2 was a much later model and that had a great screen too and the girl that bought it was very happy as some of her friends screens were far worse in comparison.

My gs1 was ok but developed issues with colours in sections of the screen and when i upgraded to the gs2 the screen was so great in comparison I thought Samsung must have sorted it. That's why i went and got the note going for something close to the gs2 with the added size and res. Being so close to a great screen limited by software in my case does drive me nuts but i could not go back to a mini phone again lol.

It will be interesting to see how the 7.7 tabs with hd samoled+ screens go as far as screen consistency goes.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] sibere:
If you can t see below 4 or 3, simply use the supercurio app and screen adujster. now I see down to 1 ( even if it's too bright due to a bad gamma curve) and I have less banding and black clipping.

now about im2 video, my screen is closer to the right hand side one than the other. I think that even though my screen is not perfect, it 's not as bad as what I see here. I must be kind of lucky.

I have a DBT note from Amazon.de.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] BerreZ:
Conclusions ?

At this point I was able to seriously test 12 Notes at home and basicaly test 4 of them in different shops.

All of them , so 100%, are faulty.16 is not enough to take very scientific conclusions and it is even possible that region of origin has also to be taken in account but I'm pretty sure that all the Notes present the same problems.No one is perfect and the peolple thinkng this do not notice the problems.

I aslo tested the same files in the same conditions on a Galaxy SII , an Asus Transformer , a HTC HD2 running on Android a HTC Sensation and even the pictures on an Iphone 4. I could not notice any flaws on these devices

I'm convinced also that all the problems banding , clipping , grey halo , pixelation and so on do have the same origin.

I'm afraid that the problem is partially hardware ( pentile technology ) and partialy software most of the application are not designed to run on a amoled screen with this kind of resolution.

So for the moment I will not continue my quest for a perfect Note , he do not exist , and will wait until Samsung aknowledge the problem and will try to fix it.

I also proposing to let Sammy know for instance at this adres : http://www.samsung.com/uk/support
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] BerreZ:
Correct

But obviously I was wrong the first time so that's why I invited them back today at my house to do more testing , and voila after a second and more complete look we all agreed that they were faulty too.So untill now I have to disapoint you all .I have not seen a perfect Gnote till now. But I don't care that you believe me or not because on monday I'm gonna ask for a refund and say byebye to Samsung and ther ****y products.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] Braxos:
Bye bye farewell

Just write as when you find a perfect device
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Yes there is, everyone has this clipping but they greatly vary in extent.

The one I asked you to do is when you display the gammatest image try to bring up the task switcher and see if the clipping goes all the way down to once the back ground has dimmed.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] SAlmighty:
Eww

By bringing the task switcher I only see number's 9 and onwards (9, 10, 11, 12, and so on...) in Dynamic / Standard Mode. (therefore, clipping goes down up to the number '8')

Movie Mode--only number's 7 and onwards ('till 21) are visible (therefore, clipping goes down up to number '6')

This was at maximum brightness in all three modes

Since you bought task manager up, I was watching a dark scene clip from "The Smurfs" and I pulled up the task switcher and bang, black pixelation everywhere. It literally looked like I was using a prototype device--I like to simply coin this as a piece of crap. I don't know if a replacement will rectify these issues, I'm pretty darn sure I should seek alternative options. :confused:
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Same thing on my end, on the store demo unit i tried it goes down upto 9 but it does not give a pixelation hell in movies. I dont understand why.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
Looking at the gammatest on mine then opening task switcher it drops from 2 being visible to 4 being visible on standard mode.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
This is w/o supercurio's fix or you have his fix but just disabled?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
I have his fix uninstalled.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
Ok this may sound weird but my clipping is improved. I cant see the clipping on iron mans face now like my pics. I see it when the guy at the end stands up.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I have noticed that at times the fix even sticks after the reboot or power off, there was a time that I had to flash another kernel just to remove the settings which was odd.

Check in a dark room.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] BerreZ:
Is it possible that we are looking at the problem the wrong way ?

I tried thesamsunggalaxynotegamma picture on a Galaxy S2 and was only able to see up to 12.But on this phone the moderate rusty nails video played perfectly also when banding is visible like the splash screen of the XDA application it is lot less noticable than on a note.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] indie:
I checked in a dark room! It is still so obvious at the end but not so bad at start and middle.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] MartijnMM:
The first row should be almost invisible, problem with the note is that all dark's are too light, so the cutoff from the darkest grey and pixel-off is too big.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] BerreZ:
Yes the left row is completely invisible.So a fix should not try to make the black less black and more greyish like with the app screen adjuster but on the contrary more black , if this is anyway possible .
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] MartijnMM:
Idd, but while Supercurio's fix isn't ready, i prefer to loose the ultra blacks

in favor of less pixelated movies.

I have yet to see an any app/fix that makes it possible to display dark blacks

in there true form (almost invisible dark black)...so I really wonder if Supercurio can do it.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I havent seen much of an update on his twitter page, so either he is busy with other projects or its proving difficult/impossible and I dont mean any disrespect at all.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] BerreZ:
Today I tried another approach , probably this has already been done.

I took some videos and photos with the Note in dark conditions of dark objects.

Taking theme my screen was already pixelated , looking at them afterwards they had the same greysh pixelation. I transfered those files to my computer , to my Galaxy SII and to my Asus Transformer EEEpad. On all those devices the blacks look OK.So it's not an software encoding problem.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
I also had pictures taken with the camera before that didnt show any black clipping or grey banding with my first screen and now they just look horrible with this new screen, looks fine on my friend's screen and on 2 store demo units ive tried. The service center placed another screen repalcement for me and should arrive by fri or sat, as I showed them the issue with the clipping on my screen and none on my friend ( on pictures )

Workarounds that also work for the Nexus?

I'm a galaxy nexus owner, and have similar problems to the Note. I see the gamma curve problem (in many cases it looks like a black-darkgray-purplegray kind of rainbow/gradient effect. It looks similar (but nowhere near as bad) as the pics here:

http://attachments.xda-developers.com/attachment.php?attachmentid=862447&d=1326930532

Mostly I see it in the black areas of videos where there are parts that aren't completely black. I will try to post a pic later tonight.

But I'm wondering if there are any workarounds for the Nexus? I can try screen adjuster, but it sounds like that only works with SW decoding of the videos? I'm using MX video player if it matters.

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
After playing around with the gamma curve settings on my notebook,I am pretty sure this is the problem.I deliberately set a very high gamma number and I get same artifact effects on the display of my notebook during dark scenes.Once I turn down the number,it is back to normal.

The problem with the GNote is that there is no way to calibrate the gamma setting.Samsung will need update the gamma setting or an app will need to be developed.

Perhaps this is why some phones are not as bad and others are very severe.For whatever reason,the gamma setting is all over the place for different phones.

I also noticed more banding on my notebook when the gamma setting is very high.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Its already been conformed for a long time that it is a gamma issue and yes I also get similar results my PC (using an nvidia card) If I set the gamma to +3.0 it almost replicates how awful it is on the Galaxy Note.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
Yes it was the most likely culprit but playing around with my notebook confirms it for me.All the evidence points to it.

There are people who says that some phones have more luminance than others and this indicates a high gamma setting.The ones with less luminance may not have this artifact issue.

Also it appears that a high gamma setting will increase banding as well.

---------- Post added at 02:23 AM ---------- Previous post was at 02:10 AM ----------

The bad news is that it may not be a big enough issue for Samsung to do anything about it.

Perhaps only 20 out of 100 people will notice the problem and out of that 20,maybe 1 or 2 will complain.The rest will still be satisfied as the screen is fantastic 99% of the time.

A gamma calibration app needs to be developed.There is one for Windows called Quickgamma but there is no Android version.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] EarlZ:
Just guessing but I think the gamma profile is stored on some chip with the screen since my video playback was severely ruined after I had my screen replaced, Im not sure if anyone reported getting a better result after it was changed. I dont know how Samsung intends to fix this issue since the gamma curve seems to vary per screen/phone. Im actually surprised that there is virtually zero activity about this issue on the Galaxy Nexus subforum, I've seen my friend's Nexus and it also suffers the same issue but not as horrible as mine, he only uses his phone for call/text/web though so it wont bother him as much.

Our only hope then is supercurio's fix whenever it comes out all though Im still processing the refund, I havent been informed if its approved or not. While waiting I also have another screen replacement this weekend.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] jkc120:
Is it even possible to develop a gamma calibration app? Is that level of control available as an app running as root? I'm just wondering how likely such an app will every get developed for the Note/Nexus.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] noteworthy:
I'm not a software engineer so I can't answer that but I don't see why not.

There is no app like this for Android and you would think it is more useful for phones as Windows PC's don't need such an application as you can calibrate the display through the video card driver.

But is there a market for such an app?It doesn't seem like many phones would need it other than the GNote and the Nexus.
