SAMOLED+ Pixel Response Time and Touch Screen Discussion & My Review of These Parts.
Hey all, I wanted to start a thread to have a discussion about these two things that are my only disappointments in this phone.
Let me start by saying I think this phone is awesome, and yes I feel there are a few other faults on the phone (lockscreen delay when running off the battery due to the CPU taking a second to kick in, weak GPS/wifi signal sometimes, heavy banding on gradients etc) But those are software issues and I know in the near future Samsung/Devs will sort this out.
But I had some big complaints that aren't (still I hope not) software issues. Firstly;
- Response Time.
By this I mean when you buy a new monitor and the response time is listed as 4ms or whatever. This is the time the pixel takes to make a full change. A slow response time will cause ghosting. And that's exactly a issue that the Samsung Galaxy SII faces. Ghosting.
I've gone through 4 replacement SII's for various reasons, and on all of them they ghosted. So it's not just my phone. Samsung bizarrely states the response time is 0.001ms which would be there would be no ghosting at all. However there is, quite a bit actually, by my testing the screen is actually around 6-8ms.
I want to see if anyone else notices it. I know there's been a couple of threads on this but I want to see if the majority of people notice this. Here's how to test, go onto white page with black text on, and then scroll down the page at a moderate pace, not to fast not too slow, try it at different speeds as well just in case you don't get it right.
The easiest way I find to do this is use the inbuilt stock news app, load up any story and it'll give you a long white page with black text you can scroll through. As you may notice if you got a decent set of eyes on you, the text will leave a trail. Also known as ghosting. To me, I find this absolutely unacceptable on such high end device.
- Colour
Also, as it's been widely reported and has been noticeable on all my GSII's, the colour temperature is very 'cool', nowhere near the perfect 6500k. As a result, white's look very blue. This is fine and you hardly notice it on it's own, however when I'm using the device at my PC, which I use on a 32" IPS panel TV I professionally calibrated, the whites on the GSII look more blue than the ocean! Technically this is a software problem and can easily be sorted when custom roms come along but jeez, this is some bad stock colour calibration.
Also when you tilt the display, the viewing angles are generally very good, however tilting the display by pretty much any angle adds an extra blue tint to the screen on an already blueish screen.
I'm an absolutely screen quality perfectionist so these points really get to me. Especially considering this is such a high end device.
Overall I'd give the display a 6.5/10.
After the colour temperature has been sorted, I'll give it a 7.5/10.
If the ghosting can get minimized somehow even slightly through software on top of that, I'd give it an 8.5/10.
Secondly;
- Touch Screen
Now we all know about the movement deadzone/threshold on the touch screen which is massively annoying, but hopefully that'll get fixed in the near future. But What I'm going to complain about is the low sensitivity of the touch screen is the best way I can describe it.
On my HTC Desire, I can tap the screen ridiculously lightly and quick, and the device will register the input, absolutely no questions asked. Absolutely brilliant.
However on the GSII the sensitivity seems to be a lot lower, I can tap the screen lightly and quickly and the screen won't register the touch at all. This is pretty damn annoying as sometimes I just tap the screen lightly normally and I have to retap things. Not very often but still. I wish the device was as sensitive as the HTC Desire.
In it's current state I'd give the touch screen an 8/10.
If the movement deadzone and sensitivity got fixed, it'd be a 10/10.
Now I'm sure I had more to write about but I've forgotten now. I'll edit it into the post if I can think of the other things.
Now as I said, I think the GSII is a smashing phone, sure there are a lot of niggles at the minute, but I know they'll get sorted soon. Just the points I've outlined in this thread are things I'm scared won't get sorted. But you never know, I'm really hoping they can get sorted/do get sorted.
As I said I've had 4 Galaxy S2's all had the above issues, and I've used 2 other S2's from friends who also have these issues, so it's widespread, I'm just curious if people actually notice it.
I've added a poll to the thread regarding these issues. Please don't lie to yourself about this stuff, if you notice it, please answer honestly
I honestly hadnt noticed any of this stuff, i even watched a video of the deadzone and couldnt replicate it myself. I also think the touch response is fine you must have a very light finger/thumb!
The ghosting i hadnt noticed probly because i dont read text as im scrolling i tend to go a page at a time and the fact that im too taken back with the smoothness that pages do scroll.
The blue tint you guessed it i hadnt noticed but then again its not often i hold my phone up to specially tuned monitors.. Then again maybe theres a reason for it maybe it helps reduce glare in sunlight, then again maybe im talking aload of ****e!
no offence but you sound like you could moan for england! chill out and focus on the things it does do well and you may notice the negatives less
Personally....I think your nuts. This is the best screen ever on a phone. I have none of those issues, the touch screen perfectly responsive, my whites are white as white can be. You keep getting your phone from the same supplier and that leads me to be what the problem is. mine is perfect in every way. lucky me I guess

Haha I could moan for england ;P
Nah it's just I'm very picky when it comes to screens. And I definitely expect the best on such a high end device, unfortunately the SGSII falls abit short on this.
It's still a great device. Really wish I didn't notice this sort of stuff haha.

Best screen on a phone possibly. It's not the best screen ever though, it's good don't get me wrong, but not the best.
And I assure you, your device has everything that I outlined in my original post, it's just down to the user if they notice it or not. When I used my friends Galaxy SII's (who both got it from different places to me and each other) I asked them about this stuff and they had no idea what I was on about, so I thought my phone was faulty and I had a look at their GSII's and theirs have the same problems aswell, they just don't notice them. (They did after I pointed it out though muwhahah)
I must not have a sgs2. Maybe its because mine is from first batch but I have none of your listed issues. After 4 devices, it cant be samsungs fault.
Heh, guys every SGSII have these issues, I'm not arguing that, was merely checking to see how many people notice these issues (not many in the grand scheme of things apparently) there's quite a lot of reports of these problems so it's just down to the user

I guess I have horrible standards. No shadowning on my phone.
The ghosting and blue-ish colortemperature I noticed right from the start. But to be honest: I really dont care. At least the ghosting is nothing which stands out of the crowd... all of them have it ... HTC, LG, Apple. The only reason you don't notice it as much, is the lower contrast on the other displays.
As for the sensitivity: It's a little lower than with my htc hd2, BUT I'm actually glad it is. The sensitivity on the HTC phones is ridiculously high. You don't even have to touch the screen and you end up clicking something, which can be quite annoying sometimes. On the SGS2 I never had any missclicks, nor did I have any non-responsivenesses. Perfect setup for my taste.
I think all of the average joe out there probably doesn't care about all this minor issues. You must have the intention to find the fault of the phone in order to get what you want to find but do you think most of us would be doing this? Haha.. Tbh I don't really care as long as the phone does what I want without falling apart. lol..
Yeah I was a bit surprised by the ghosting, having seen the response time claims, but neither that nor the colour temp (on 'movie') have really bothered me so far.
What has irked me a bit is the image sharpness. On a site like m.engadget.com the coloured text on white background has a dark outline all around it, which to me looks horrible. Anyone else noticed that?
I think the ghosting issue is due to the low fresh rate of the touch screen.It's lower than 60HZ.
When you scroll the screen,the animation is not smooth enough,so you see the ghosting.
It's more of a visual persistence issue.
I remember when some choppy animation showed in CRT,I can see ghosting.
Never the less,when your finger leave the touch screen,let it scrolling itself,you can see the "ghosting" would be less noticible.
But you can still see it,that's because of 60HZ refresh rate of the Display.
I just wondering if there is any way to change the fresh rate of the touch screen.
What are you doing that's causing ghosting issues? There is a definite color temp issue but that's how every amoled screen has been so far. I would take a little bit of blue tint over the black color performance
The thing that causes the ghosting, as I said in my original post, it fast movement. The screens pixels can't change fast enough so things leave a trail.
As I said the best way so see this is to loadup a long page with a white background and black text and then scroll down at a moderate pace, fast but not so fast you eyes your eyes canty follow the line of text. If toy do it right and you've got a decent set of eyes you'll see that the text leaves a trail.

hi,
You are not the only *nut* i noticed that on my device the grey sux big time,... specially on rgb 100 100 100 have a look here: http://forum.xda-developers.com/showthread.php?t=1084543
My white is ok, but the grey goes magenta,
PLUS
if u go to 160 dpa u will see the effect better on greys and gradients which involves grays!

Yep, there's a lot disappointments with the screen on this phone. However as the poll is so far proving, majority of people don't care for quality as much as us. Only a few others care/notice about the things we're complaining about.

Thanks .. Thats the funniest **** i have read all day...
Theres nothing wrong with my sgs2 and ive owned Hero's Desire's Nexus One's and even an LG2X.. This phone is superb.. This dude does sound a bit anal..
Hey. I can definately notice ghosting on this screen if i purposely try to but as others have said, it doesn't bother me in the slightest. When watching films or playing games it's non-existant.
As for the whites, you yourself stated you can't really notice until you hold the device against your professionally calibrated screen. How are the blacks in comparison? Out of interest, how much was that screen/calibration.
I think the main problem with alot of peoples gripes is focusing on only the weaker aspects of the phone rather than the device as a whole. People want perfection which unfortunately doesn't exist in the world of electrical consumer tech.
now i see this horrible grey everywhere i cannot even look at my phone any more!
I hope that this issue would be enough to change my device!
Hey drm111, as you know I have those problems too.
Did you have them on all your 4phones?
1) As you know I have this topic in wich one screen had this blue ish coat on the screen, noticable from the angles you talk abouth. But the other one does not have it.
So maybe not everyone has that blue coating? Did you investigated that further?
2) As you also know there is this yellowish/darker 1/3 of the left screen, probably some don't notice it. You have to be in a dark room or in a light one really looking for it. You read abouth this huh?
But I you didn't post it here. Aren't you having this problem? And did you have it on al of your 4 phones?
3) Ghosting, yes i notice it to. No sharp text when scrolling,is that the ghosting too?
I have this first generation ipod touch, text stays sharp when scrolling. Should be the case here too.
4) Than you have the grey tints, wich turn pink. You can see it in the topic of nongrata23. But some phone don't have it it seems. Software or hardware?
We need to figure out what is 'normal' and what isn't. As I don't want to send my phone back if it is normal at this point for all the gs2 that are on the market.
Let me start by saying i used to work for a PC magazine and was among those who blew the whistle on the nVidia texture replacement fiasco surrounding the Geforce 5800. I can see a single texture out of place in a high FPS game, so my eye is VERY keen.
The colour of the SGS2 is slightly blue yes, but mine is no worse than the average LCD, including the Retina display.
Response time is seemingly slower than the previous AMOLED screens ive seen, but again is more than a match for the LCDs out there.
I would say samsung have made a trade off between the sub pixel density and other factors. It works for me just fine.
The 16bit thing is interesting. It looks to me like the screen isnt 16bit, but it is using 16bit at times. Thats a driver issue.
Has anyone noticed that the warm colors are only available when looking at the display head on?
Tilting just a few degrees does keep the image sharp, but the colors are much colder...
What im asking is - is this normal, or should i get another?
Well - i just spoke to supercurio, he says its to do with crappy glass treatment, not the panel itself.
Will go and see what else they have at the store tomorrow...
Only a slight change in color for me. Nothing that I would say is an "issue". But, of course, it depends on your personal perception...
What more annoys me is the banding (gradient) and the oversaturated, unnatural colors that I experienced with all AMOLED displays until now. I prefer LC displays...

Seems to be common in Samsung devices but not all exhibit such a bad viewing angle, my Galaxy S and S8500 didnt have any color temperature changes when tilted even at extreme angles while my Galaxy S2 had a slight shift to green, while my note's first screen didnt have any hint of temperature change but after the screen replacement I had a blue tint with really bad viewing angles.
I havent seen how bad it is on the Tab7.7 but im guessing its gonna be similar.
EDIT:
Found this show case video on the Galaxy Note about the viewing angles, their unit doesnt seem to exhibit any color changes.

Don't let me stop you, just letting you know that its common among samsung devices but not all of them exhibit the same issue, a friend dropped by after getting his tab 7.7 about 2hrs ago and there is no color change at an angle, so yours might be faulty.

Man I don't post too often but you've gotta relax a little bit, take a chill pill.
The other guy does have a point in saying that its common to all Samsung devices especially the Galaxy S line of devices. I've had a Galaxy S2 that had color temperature change when viewed from an angle and even my current nexus does it.
I got my galaxy tab 7.7 2 weeks ago and I'm very happy to say that it does not have any temperature color change even viewed at an extreme angle.
And this guy did an unboxing and also mentioned that he has no color changes when viewed from an angle as well

I hope you find my "opinion" relevant but whatever, relax and chill out.
Also he did add to his post that he saw a friend Tab 7.7 and it didn't have the color change that you mentioned.

You might also like to read the op, look at my profile page and signature and make some deductions regarding the entire reasoning process as well.

That you notice.
This would be the first OLED or any screen (LCD obviously is bad for this) that doesn't change a bit when viewed off axis then. I have seen the Note, the Infuse, and even Zune HD screens and they all shift a bit when viewed at an angle. I would be very suprised if this did't shift at all but I suppose it may be possible.

Look at the video posted above on the note, it does not have any color temperature change as far as I can tell. Before I had my screen replacement it was similar to that.
Just bought three more for the office, all with perfect screens. The first was a dud, store took it back after some cajoling.
Thanks for the help.
No colour change with mine. Best screen I've have ever looked at.

I also took mine back because it turned blue when i looked at it at a small angle. New one is not perfect either, still distorting way more than screen on my lcd 8.9 though.
I wonder how many people just dont realise that small color distorion is normal and never complain and how many actually haver crappy screens (since i assume they are pretty much the same manufacture date)?

I also wonder what you're doing with your tablets... When I'm using mine I'm holding in front of me, I don't tilt it at 78.5 degrees only to see that physics does its job with the glass filtering/separating colours at certain angles through reflections between the two glass surfaces.
You can't just have everything: a super-tough screen glass, brilliant colours, high resolution, crisp sharpness, 180 degrees viewing angles in every direction.... Be happy with the best screen in a tablet so far!

Actually you can. My very first 7500 was PERFECT. As was an excellent Incredible S i owned.
Ive now seen 4 of these and none had what i would call a good screen compared to the LCD in my first 7500. Changing up to 170 degrees on it only affects the brightness not the pixels visible color temperatures.
Please prove me wrong!
Anyone have any links to videos showing a Note rendering dark grays correctly?
watch the demovideo on your note.
The dozens of reviews which acknowledge how good the screen is proves you wrong.
Pfffff. Tests with Samsung handselected devices. Or do you think that Samsung will send defectiv devices to the testers?
The note I got from bell has no screen issues at all.

Mine is fine with some tweaks. Primarily -40% contrast. I can see down to '2' on that test image. I also notice little or no blotchiness in dark videos any more, although I did before adjustment.
It's a software issue IMO.

I share the same sentiment as no one with a 'perfect screen' has shared it. The best I've seen is one w/o any black clipping what so ever since his gamma test result is similar to a Galaxy S2 but I do see a few visible horizontal lines on a grey screen. Its not perfect but its with in specifications aside from the lines.

To the unwise it may seem incorrect since they are only looking at the smaller picture and dont really have a clue on what this 'objective' test is for, let me give a real life example:
Using the Kindle application for reading ebooks gives you the option to use a black background now some screens have very visible blotches even if there is a text on the screen and they are become unoticeable when there is a text above them, this of course matters to someone who reads ebooks in their bedrooms w/o any external light source or to someone who watches movies like me. You see if we ask someone to open kindle and load up something and do this and do that, it makes the 'testing' more subjective rather than just test it in a pitch black room with a black image displayed.
These tests may sound silly to others but its the best way to get an objective result, remember people theres a difference between 'its not there' and 'i dont notice it with normal usage'.
here is an example that hopefully may enlighten you people with self proclaimed perfect screens so you may understand why its so difficult for others to accept such screen exists because with several replacements they havent seen one yet and people always claim that defects are the extreme minority, if its true then no one should need more than 2 replacements to get these perfect screens, correct?
It is also common for others to be dismissive of any screen related issues, you can be dismissive all you want provided you show an objective result. till then your screen is just as flawed as everyone else.

Are those dark rings one of the issues that everyone is complaining about? If so, I'll have to look at my unit, but I suppose I've just been extremely lucky. I have yet to notice any issues. That's not to say there aren't any issues with my device (possibly), if I look really hard, in very specific conditions
I do not have any black blotches or whatever.
One of the issue I have is the gray screen. It has somesort of texture on it but it's tolerable since it looks like a texturized wallpaper. No problems with playing videos at all, everything looks crisp and clear. So far I am enjoying it.
Also, another issue is the camera. When I am around those long florescent lights, there seems to be some wavy things on my screen. Even on video. I guess I got to avoid those lights in taking pictures. Haha.

That Image i used came from the Tab7.7 forums which shows the issue and practical scenario at the same time. Its an example of the darker blotches in blacks, not really the main issue on the Galaxy Note but one of the many possible yet rare issue.
On my end, my first screen had some blotches but they were not visible when I watch a movie or read an ebook from the kindle app, the 2nd screen I had did have a home button sized like blotch at the bottom which was visible when reading ebooks unless a text is close to it, in movies/shows it is only visible when the entire screen goes black.

Once again, I guess I have been extremely lucky with both my Note and my 7.7, because I have yet to notice any of these issues with either
Black clipping and banding = software. Therefore, irrelevant from a hardware perspective.
The splotches that you see in the most dark of conditions are the artifacts of the manufacturing process. Under normal 0% brightness (without using additional apps like screen adjuster) you will not be able to see these things assuming you've got a good screen.
The only things you need to look out for is color unevenness and brightness unevenness and in some cases, the manufacturing process is so prominent that it seeps into the normal brightness (0% and up range) and it is visible.
The fastest way to tell if there is something wrong is to turn off all auto-lcd power management, set the brightness to 0%, and to simply pull down the notification menu and view it in a dark place. That'll reveal most of the problems that you might find in a day to day situation. If you see nothing there and the screen looks crisp, don't bother looking for more. They will not appear in normal real-world situations.
No blotches on mine. Very happy with the quality. The color profile seems nicer than on my i9100. The only screen I had with noticeable blotches (only seen at full darkness) was on my T989.
So ya, very happy with my Note's screen. White International N7000
The witch hunt started with the original sgs and continues with the note.
Im on my second note plus a screen replacement and screens are flawless. Yes there is somme banding on all of amoled screens. Its partially software because running ics alpha build, most of the banding is gone.

Hi everyone. After GS1, GS2 I've bought GS3.
Really disappointed for the viewing angles (on whites/grays), the worst I've aver found in amoled/ips lcd recently.
As I tilt the screen 15-20 degrees (normal use movement exspecially when you write/use it with one hand) during mail, web, whatsapp all the whites begin to show a sort of polarized/light blue reflection that seems to be caused by Gorilla Glass/amoled interaction. Very very annoying and tiring for my eyes, and of course not beautiful to see on a 600€ 4,8" display.
On Italian forums I have to say 90% of users experienced this, but maybe in my GS3 this effect is more prominent, difficult to say, I cannot compare by now.
I'd like to have feedbacks from you, don't know if return it and buy a new one.
Cheers.
Im swapping mine in store for the same reason.

Hi.
Is the new one replaced better?
I never understood why viewing angles were a problem. You're using your phone wrong if you need to view it at a 20 degree plus angle.

Never had viewing angle issues with past phones. Never.
With this GS3 simply cannot move it, or I have a blu reflection.
Just want to know if it's just mine.
It's the same with all amoleds ...but I don't think it affects the usage that much and it's only noticeable on plain white backgrounds ...
Haven't been to swap it yet. Im going tomorrow i'll let you know. Been having call issues were it sounds like I've gone under water about 1 min into some calls.
My mate works in a phone shop and said he swapped 3 sgs 3 for call issues today alone

Thank you nik
I have exactly the same thing on the lower part of the screen. The grey's temperature is "colder" than the rest of the screen. If you test the screen with "*#0*#" with the three diff colours is fine, the "issue" is only with white and grey background.

I see but the thing is i had sgs1, two sgs 2 ( white and black), two galaxy nexus (white and black), all of them had a blue tint when viewed at an angle .... Though I also know many have said that they don't have tint but I never got any galaxy without tint just my luck I suppose... Htc one x slcd2 doesnt have that issue but battery life is too poor on it that's why got sgs3...sgs3 is superb in every way..

This sound quality issue sounds very much like a problem described in other threads.
Perhaps you have already seen this, but if not, be aware that the problem has been solved by the majority of people simply by switching OFF the "noise reduction" feature under "Call Settings" (it's set ON be default)
Thanks for the reply but I had seen the other threads and switched off noise cancellation but still suffered from the "underwater" problem
Thanks

Sorry for the delay
Sorry for the delay in replying to this thread. I have just got back from the Carphone Warehouse where I checked four different Pebble Blue S3's...guess what.....They all had a Purple tint to them.
When They where first booted up they looked "OK" but when I turned the brightness all the way up and open a white webpage like google you could see a purple hue/tint to the screen but it looked fine when you look at it straight on,
I only have another 4 day before I can exchange mine for a new phone, seriously considering getting a HOX instead at this point. Or failing that sitting in a Samsung Service centre until I find one that doesn't have this awful tint.
I'll keep posting on this thread if I manage to find ones without the tint but I've got a feeling that the CPW UK has got a bad batch in at the moment.
My screen seems okay in regards to tint overall but the top 20% of the screen or so is bluer othan the rest and it gets gradually worse as you get to the top edge. At first it didn't bother me so much but now it's starting to get annoying =(
Hey guys,
I've had my nexus 4 for a week now and I am super pleased by it. The phone runs like a dream.
The only issue I seem to be having is that I can see the IPS sensors even with the screen on!.
I'm talking about the little transparent-gray squares all over it, not about the super awesome dots that you can see with direct sunlight.
This is flipping me out!
Is anybody else having this problem with it?
I can't appreciate the beautiful screen because of this.
Also, when displaying single color frames specially dark ones, like on the clock app , the colors are not really solid.
I get this vertical stripes that are approximate to the color but not quite it.
Im posting a screenshot but I don't think that youll be able to notice it since it may be a hardware problem.

That's a hardware thing, not visible in screenshots. You'd need to take an actual picture.
Are you referring to the dot grid that is visible in direct sunlight? Everyone has is. It's because of the fact that the screen is integrated into the glass.
I think it looks kind of cool but that might just be me.
Edit: Gotta read the whole thread first I guess you're not talking about the dots. I have no idea what you're talking about then.

Question to the OP. Do YOU see anything wrong with those images, or is it a hardware problem? I can't see any difference between your screen shots and my phone.
Damn it man, now i see them too -.-
I went to the clock app, and i can see some stripes on the left but mine are vertical.

is there any thing to worry..

Haha Dude that's the digitizer. Don't worry. It's all cool.
Chill out people.. Its just the digitizer that you can see, so close to the screen for better touchscreen responsiveness. The most likely reason you can still see it with your device screen on is that you have your brightness too low.. Put it up
even amoled screen are also the same

When I first got my Nexus4 the weird screen was the first thing that popped out at me. Between the visible digitizer matrix that glints when it catches the sun wrong, to the odd rectangles that can be seen behind the screen I was initially bummed and thought about returning the phone. It doesn't even bother me anymore
This is my 8th android device and the first one that has a funky screen like this, but it really isnt a big deal. Under 95 percent of conditions it looks really nice
I have been able to see the digitizer on every single capacitive screen i have ever owned.
@David_Azar I have to agree.. initially I was disgusted by how prominent the digitzer pattern was, I've never had ANY screen show it as much as the Nexus 4 does.
However, the vertical stripes you're referencing is commonly referred to as "banding". I have this on my Nexus 4 as well, most visible on grays (especially darker grays).
I have been doing some research and I believe the banding issue will reduce over time. If you check your screen when displaying a white background at max brightness, such as gmail or chrome browser, you should see a slight yellowing of the whites. It appears this can be due to the adhesive they used to glue the digitizer to the screen not curing completely. After several weeks of use, the heat from the processor will help cure the adhesive causing the yellow to disappear after a while.
I cannot say for certain that it will completely resolve the banding issue, but I have noticed that the worst banding is in the areas where the yellow tint is most prominent. I have also been testing my display every day to monitor any changes, and I am happy to report I do see a minor reduction in both the yellowing and banding (I've only had my Nexus 4 for five days so far).
Give it a couple of weeks, run some intensive games to get the processor to heat up every day. Keep brightness at max for the next few weeks and let us know if you see any improvements.
As for the pattern of the digitizer in the glass.. it's not going anywhere so get used to it. I don't like it much either but it seems to be less prominent once you start becoming used to it.
Good luck, let us know how it goes
Hey man,
Curiously enough I've never had the yellow tints everybody's complaining about. I'm used to The digitizer matrix ( rectangles) buy at first it was really weird. I was coming from a non HD display ( a RAZR Maxx) so naturally, I expected that my N4 would have a perfect screen.
I've had my N4 for almost two months now and the banding has not reduced. I made some research over the last month and I found that with some kernel settings for saturation the banding is reduced. I'm not sure if it is really reduced or the clear gray tones that have the banding just don't appear anymore because of the saturation.
The Trinity kernel reduces this a bit but like I said, your screen will look life a f*** ing AMOLED.
Right now I'm using the kernel provided by the 123 FAUX CLOCK project. I'm using the LG factory presets and for the most part I'm really happy with the screen. If you or anybody else comes up with a different solution, let others know on this thread.
Peace brothers.

Just for kicks, if you stop by a T-mobile location compare your screen with the display model and see if you can spot the yellow tint on either screen (on a white background)
I will update this thread with my phone's progress (or lack thereof if it stops improving).
I get banding issues also, more noticeable in grey backgrounds; but I can I see them in other colors if I look hard enough
I use a dark black theme to avoid looking at those bands
I can say this. I've had a ton of devices..latest was s3 and I'll just say I'm stoked to have IPS over pen tile. Just knowing HD was plagued by this alone was enough for me to ditch Sammy all together especially after seeing rgb on note 2 was no better. This is my opinion of Samsung's design ...I know why they chose it but I can't and won't buy another amoled until they get another tech in order. So now I say kudos on IPS but I'm surely a screen purest and I found these hardware screen/digitizer artifacts you speak of and to me its so much less noticeable. Your not alone. You just like good clean HD like me. Lol HTC one should be a nice one to check out...

That would be a little like kicking myself in the nuts. Nothing good can come out of that.
If I spot the yellow tints once, then I will always look for it. I hate doing that with the banding but it's an automatic thing.
I dunno why but it really bums me out whenever I have a problem with my phone.
Let's keep posting of someone finds a solution or something .

I've got the quite visible digitizer rectangles too. In anything less than a dark room if the phone is not on a perfect angle they are visible.
I can't really tell if "everyone's" is like that, or just some are "worse" than others.

Here's an image with them visible with the screen on (and at an angle) - difficult to take a photo of - but much easier to see with the naked eye.

Few more with the screen off.

Went and checked out an Optimus G today (Nexus 4 isn't actually released in Japan). Given that a Nexus 4 is just a remodeled Optimus G I thought it'd be worth comparing screens. The digitizer matrix is barely visible on the G I was looking at with the screen OFF. With it on you could almost see it at some angles. It is much more visible on my Nexus 4 which you can almost always see with the screen off and at an angle and often with the screen on.
I'm leaning towards my phone being "less than a perfect example of a Nexus 4" and not the "norm" at the moment.
they are much more noticeable in Rev 11 devices and they where barely visible in Rev 10, i am sure that there is a technical reason behind it

See that explains it a little more. Not sure I see the logic in putting a screen with pretty decent viewing angles on a device and then sticking a really visible digitizer on it though.
I've contacted the seller and I guess I'll wait and see what they say in regard to it.
