[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] SamSpader:
Bought my Note back in Nov 2011, on the first day it officially launched in my country. Never had any banding or tint issues, or at least none that I could notice.

Last week the screen suddenly went dark. The display was still readable as long as there were only a few pixels on (like in Settings), but went totally dark when the screen needed to display a full page (like the browser). It seemed like the screen power dropped when it needed to light up more than a quarter of the pixels. After a few hours vertical white lines started appearing on the right side of the screen, similar to the lines when regular LCDs become defective.

Brought it to the local Samsung service center. They said they'll repair it in 3-5 days. I was skeptical since I knew that they either had to replace the whole screen, or the whole unit. Got a call after 4 days and it's now as good as new. The whole screen module was replaced, which I think weighed more than half of the whole unit.

Never thought that Samsung service would be as good, or even better/faster, than Apple. Of course, I was probably just lucky that the authorized service center in my area had decent service, and that Samsung stocked Galaxy Note replacement screens locally.

It's not for everyone, but it's still the best phone I've ever had. I was surprised I didn't even get upset when it started conking out, which I used to do on my previous phones. I guess being really satisfied with the phone for 5 months lessens the distress you experience when it first lets you down.

Thats the biggest advantage samsung has in the Philippines, local service centers and you dont need to leave your phone with them while they order the replacement parts. They dont stock the parts locally though, replacement only takes 1-2hrs on the screen.

Just to report some observations, when I tried flashing imilka's CyanogenMod 9 v02, the clipping in the gammatest.png seemed to be improved. But gamma was still brighter than it should be, and clipping/crushing was still prevalent in other pictures and videos:(

I've been going back and forth with Samsung for the past month or so, and they still haven't acknowledge the problem. One technician told me he would get back to me in two weeks, but when I called at the end of 2 weeks, they told me he had resigned! :mad: They did eventually offer me a refund, but I'll only be able to go to the service center at the end of the month due to exams. I hope they don't suddenly retract their offer or deny that they had offer a refund:(

ok guys ... my friend got a south korean LTE model E-160L ... it has no Blocky blacks issue as the video playback has a grey overlay effect on whole screen so the blacks arent pure black in the video ... result .. no blocky blacks but other colors look pale and dull ... so to me blocky blacks isnt a issue anymore ....
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] z00h:
I'm on a second Note now, first one had all possible screen issues, ie the tint fluctuations, poor gamma and a stuck/dead pixel which appeared after a week of use.

The current one is flawless, the screen is perfect there's no fluctuations, gamma is fine. It really is a joy to use (finally!)

One thing I've noticed is that the screen brightness feels lower (at the same setting level), ie the gammatest.png is darker all the way through to 1 but I can see every number unlike on the old one which clipped at 3. Any comments on that?

Where are the couple good ones seen lately comming from?

Dear z00h;

Could you please tell us where you bought your first and second Notes, as well as the ROM version and place of manufacture of the latest one?

Thanks
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] z00h:
They are both the same, manufactured by Samsung, battery made in Vietnam 02/2012, same rom. Both bought from amazon uk. It's basically the same batch.

It just shows how poor Samsung's QC is.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] A_Saknussemm:
WoW! you are right, this IS scary.

I was hoping the production line management would get more consistent results as they produce more devices. That as Sprint got their devices ordered, the QC would indeed improve. Maybe the couple good/passable ones talked about here lately are just random accidents.

I've only seen a half dozen in Spain and they seem to be good ones, or at least their faults are not as obvious as the dead pixels or color temperature instability (only seen 2 outside of a store with subdued lighting). So far getting a good screen feels like a lottery, or at least contacting users critical enough to see the faults.

Wonder if any senior member has any idea of the percentage of XDA members make up in the overall Android device pool. I suppose the number is extremely small counting all devices, but maybe high end device owners frequent the forum in greater numbers, or at least are more critical of screen quality.

Really bad in Samsung not admitting the faults, for the is a HUGE potential for the Note in the Art/Design community. There are already a growing number of Deviant art members using the Note with amazing results, but the moment one gets a bad screen if Samsung's attitude does not change the whole community may dismiss the device.

HTC had a chance but blew it with a poor digitizer; Samsung has really started something special here with the Wacom stylus and the happy middle size(for me anyways). I myself missed having one since my WM20003 (Palm too!) not just for drawing, but graffiti text input...

Thanks, A.S.

I read the first few pages but couldn't proceed with the other 100 plus. Just curious, did anyone reach out to Samsung concerning this? I would think with enough complaints something would happen (recall, better devices being swapped ect).
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] fluoxethine:
IMO the technology behind this new HD Super AMOLED is in its infancy an the quality will vary. Samsung won't do a massive exchange of devices. I think that the easiest way will be to complain to your carrier or distributor.

Samsung will never agree that their screens are poor.

Also look here at specs:

http://www.samsung.com/global/microsite/galaxynote/note/spec.html?type=find

http://www.samsung.com/au/smartphone/technology/super-amoled.html

lack of any statements that it is a full 24 bit display ; )

@$%^@$%^ Samsung! However I'm glad that I won't find Amoled in Galaxy Note Tab.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] SpyderTracks:
If I understand correctly it's not an issue with hardware but rather with software. Release by release of firmware has improved the issue, and since ics uses full hardware support which GB never did, the issue is almost resolved but certainly improved beyond recognition.

IMO the note was always intended for ics but they released it early, so the true note experience will be limited under gb.

Thanks for coming back to the thread with "The rest of the story", an amazing story indeed!

And now that ICS has been finally released for the international Note (http://xdaforums.com/showthread.php?t=1646023), has anyone with screen problems seen any improvement with the new official ROM?

Unable to do the testing since I have swap to the new unit after I notice the screen issue. I do a lot of research and seems like it is not the software but more to hardware issue. I may be wrong.

Don't sell. demand for a replacement. By selling it off, you will pass down the issue to the new user.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] hp79:
This has to be a hardware issue. In my experience from last 2 months of constant return and reordering, there were ones that have this tint changing problem, and ones that doesn't have this problem. All of the ones I tried had the exact same firmware, UBKK2. I tried rooting them, installing different firmwares, but nothing helped. All of the black ones had the screen tint changing problem, but only some of the white ones showed the problem. The last two white ones I had didn't have this problem. That's when I stopped sending these back. Actually, I would have stopped on the one before the last one since that also had a good screen, but I had to return it because the screen scratched so easily with a felt tip wacom pen. After that, I put a screen protector as soon as I got my last one.

I also had a Samsung series 7 Slate PC. That also had a display hardware problem but that was a PLA display. I replaced it twice, then finally got a refund directly from Samsung after 5 months of sending my Slate back and fourth. After all this, I'm kind of hesitant on Samsung's low level of quality control.

Thanx to all and one more thing....

Dear friends

Im posting once again to say thanx to all for their support and contribution to a problem that eventually appeared to concern many!

I dont know what mobile I would have ended up with if I hadn't read everyones opinion and experience.

I do have one more question though and would be oblidged if anyone can share their knowledge since I have no other threads in here and therefore little experience with the way XDA blog works.

Beleive it or not, only just yesterday I noticed this: (posted an attachment pic also)

On the left and almost bottom of each page of this thread, there is a TAGS section and I noticed 2 titltes there... One says "pedobear was here" and the other says: "lame thread is lame".

My questions concern this...

A)Are these tags created by normal readers or some sort of administrators?

B)Ok, pedobear was here and I have no objection with that. I hope the guy is doing well! But...

Why is this thread lame and under what criteria is a thread characterized as lame?

Was I supposed to call dancing girls and order beer when I first started it??? MAybe a band too???

If so, I trully opologize to all those who went throught the trouble of posting here because...

When I first posted here,I thought that through this thread I could receive some help with my problem and maybe even others could read about it and also be helped if concerned. I thought it was about sharing opinions on a problem.

I didnt know that I had to set up a party so someone wouldn't call us lame and nothing could be done about it!!!

Anyone who knows how this works, or even has an opinion please share cause I could be wrong but that little thing I saw ruined a great feeling I had from all the guys who freely offered their help in here.

Thanks again

stay true
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] A_Saknussemm:
A couple things...

Like Gus, I'm kind of new to posting on forums, and although I've read very good advices from XDA, just after his last post have I noticed the tags. So pardon the newbie question I too share with Gus.

The other thing is more of a concept for a workaround (kludge maybe?) to the color temperature changes on light background; not even tested but maybe worth a try:

I've read Mozilla is launching a browser for Android with the choice of displaying light colored text on a black background. This will save battery power on AMOLED screens but might also help ameliorate the light background color changes.

Using the "inverted text" setting, the actual text color might be changing as well but if the chosen text color is a bit saturated (ie. more reddish than pink) the defect might be less noticeable.

I do a lot of reading at night and find lighter text on a dark background more comfortable; well either that or I've read too many novels on AllReader!

Thanks for sharing all the precious info.

Sorry if this has been addressed before in the thread, but the search function isn't finding anything on the matter.

My Note is suffering from the clipping issue pretty strongly, except for when it's in Dolphin. I've yet to see clipping of Any sort in Dolphin HD Browser.

Is this the case for everyone? And if so, any idea why this is?

I've heard the idea that Dolphin doesn't start blacks from 0, but they look like very deep blacks to me.

[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] fluoxethine:
So here is a html file generated in OpenOffice with four columns representing greys, red, green and blue color. To test your display open it in various browsers and check where all columns start. It is easier to distinguish barely seen cells by zooming in and checking if there is a contrast between black number and background.

For example in Opera my display starts with visible cells at: 4, 3, 2, 4 respectively.

Banding can be seen for example in green where cells have same color. On my display it is:

2 = 3

4 = 5 = 6.

Firefox is 16 bit, so there are blocks of cells - cells from 0-3, 4-7, 8-11 and so on have the same color. Also there is green tint in the first column in cells 44-47 and 52-55 for example. Dolphin HD behaves same as Opera.
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] swavab:
Sorry to ask guys..can any one differentiate these words..banding,clipping,black crush..these are same or seperate..? I think me got black crush where contrast black areas are pixelated in gallery and videos..? Is it same with those..
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] fluoxethine:
For me it's all the same. We talk about 'black crush' when we consider lowest values of the RGB and 'color banding ' is for all the rest.

On test chart in the previous post viewed on my Note 'black crush' is rectangles numbered:

0-3 for white

0-2 for Red

0-1 for Green

0-3 for Blue

They are just pure black.

For color banding I can find similar sets of a few rectangles which have the same color, but with higher RGB values.

Some people say that black crush was corrected with ICS but not the color banding. You can easily get rid of black crush by rescaling color space and starting from RGB(5,5,5) as black RGB(0,0,0). However IMO it could be better if there was dithering used like in gifs. Unfortunately each display differs in amount of that color banding effect so corrections should be made individually for each display. Probably the user should correct manually the whole color chart presented in my previous post.

Note Pre-purchase

Hey Guys, getting ready to purchase a Note and would like to know if there is quick and easy method to check the screen while I'm in the store. This way I can make sure the screen is good. I already have a SGS2 that has a blueish tint when viewed at an angle and would hate to find out my new note has similar issues with the screen.

I browsed thru a few posts but did not find anything about checking inside the store before purchase..or maybe I missed it.

edit: will this work to check the screen? Turn brightness all the way down, open S Memo app with white background and look for changes in colors when viewed at angles? Or is there another way?
[Galaxy Note GT-N7000 Q&A, Help & Troubleshooting] shchiam1978:

Guys as you all now i was quite active on the thread a while back. I believed there were no good screens out there as i saw 6 different notes bought from various places and countries. They all suffered from the black crush / gamma issue. My wife just got her upgrade from t mobile uk and is a galaxy note and guess what, no issues. This is the first note i have seen. The gamma png test is almost dark all across the left and not just cutt off at 4 during normal light. In pure darkness it is still cut at 4 but again i must stress that during normal use it gradually goes to black on the left but the films are much much better. The iron man sample is also very very good. I firmly believe now this is a hardware issue as this is fine. My note had the screen replaced and still has the issue. My wifes note is perfect.
