Does anyone else's screen have very low gamma? Using Display Tester app I get a value of 1.4. A standard lcd screen should have a value of 2.2. I also notice this when viewing video in that darks parts of the image have low contrast. Changing the display mode or brightness does not seem to make a difference to the gamma. I think I will take the unit to a Samsung center and ask about it.
I have a black P605 16Gb.
Anandtech did some pretty exhaustive testing of the N10.1-14's display. I think they would have caught what you've described.

This is exactly what i was posting about , the gamma is broken on note 2014. Sure the colors look great but hallf the time you cant see many things in games which shud be clearly visible i dont get how more ppl havent noticed this. Only workaround is to set the brightness way up n use movie mode
There is something wrong with the back lightning. If viewed from an angle, especially diagonally, the screen gets washed out. This is more appearant when in a dark room viewing a dark image. Having my iPad 3 next to it and it does not have the same problem. I guess it's the same problem that some nexus 5 users have. Going post a comparison image later if I get around to it.

yes its the case with all note 2014's i think because the ones at my local samsung store on display were the same way, however i think this has to do with it being LCD technology (also as the review above states they are using some sort of non traditional white on this display) not super lcd. On the plus side you may however notice the wash out is only most apparent on black or darker areas.
Im not sure why the calibrated the gamma this way though.
I just received a new T-Mobile Galaxy Note 3 and I'm wondering if there's a problem with the screen. As you can see in the attached photos, when the brightness is high (about 50% or higher) and the background is white (or other light color), there is significant and noticeable discoloration in all 4 corners of the screen. The second photo also shows that there is an area that is slightly darker (grey color) that persists constantly.
I've read through the forums and don't see any specific mention of this issue with the Note 3, so I'm wondering if anyone has any idea if it's a bad screen, or do all Note 3's display this behavior with high brightness and light backgrounds? If anyone has any thoughts, please let me know. Thanks!

Do you also notice the discoloration when using it with Chrome or the Internet browser? If so, replace it.
is this a NEW one or a refurbished replacement/exchange? seems like the screen is bad. mine doesnt look like that at all. if its a replacement have them send you another one. could be previous water damage
do you have a screen protector on it? maybe its polarized film and causing that effect?
Yes, the discoloration is present in all apps. The seller told me the phone was brand new (not refurbished) and there is no screen protector. Thankfully, he has offered to take it back and give me a refund. Thanks @Limeybastard and @rlee008 for the help!
Iam confused on which tab to get ,since both are priced similar in the U.K , also this will be my first tablet . few questions i have is
1. Is the AMOLED display of tab s significantly better than that of Note 10.1.( iam impressed by the display of note 10.1 but hadnt used tab s)
2.does the extra 0.4 inch of tab s make any difference?
3.is S-pen really useful productivity tool.
4.Which one is overall a better tablet(VFM).

I had a note 10.1 2014 till it fell and the screen broke. I replaced it with the 10.5 tab s.
1. Yes, the amoled display is significantly better and nothing compares to it. Watching movies on the note annoyed me because if you weren't at the PERFECT angle, then parts of the image looked slightly washed out compared to the rest of the screen, if not viewing dead on you have the same annoying issue which is compounded by the back light being on on lcd's so the blacks are dark grey and they exhibit the same washed out look if not viewing the screen dead on. Amoled screens don't have either of those issues, even in extreme viewing angles the image on screen is the same as viewing dead on, and the deep blacks are awesome as the pixels are not lit and this alone would have made me upgrade even if my note wasn't destroyed.
2. The screen size difference is negligible and I don't notice a difference really.
3. The S Pen is a very good tool for those who use it. I have a note 3 and don't the s pen with it, but on the tablet I used to use it a lot for school. Note taking on the tablet with an app named Papyrus was very convenient and that is the only thing that I will miss dearly from the note tablet (I'll be so pissed if they announce a Note S before the end of the year)
4. Overall, for the price, I'd have to give it to the Tab s. It's slightly bigger, way better screen, thinner, lighter and has much better battery life. I'll check out getting a stylus later on when school resumes but for now, the Tab s wins.

The reasons why I purchased a Tab S 8.4 were its awesome screen quality and high grade processor. For the later, the poor touchwiz optimization and the average gpu led to disappointing results. But well, the screen IS awesome !
Or is it ?
At first, I was truly impressed. But after some web browsing and reading e-books, something felt wrong with the colors homogeneity. On white backgrounds, the right part of the screen in portrait mode would tend towards a yellowish tone, while the left part would tend toward purple tones. Nothing obvious, but quite annoying when noticed.
After trying around with different backgrounds, it become more obvious with certain colors. The one used in settings background for example: The left side of the screen is deep blue, the right part is much lighter.. and greener.
Further investigating the issue, I figured it is most obvious when watched in the darkness and using dark colors: RBG such as R:0, G:10 , B: 20 or even R:20, G:10, B:0
Did anyone else notice similar issues ? Would you guys mind trying to create a R:0, G:10, B:20 (#000A14) background and check the result on your tab S in a low light environment ? On mine, it results in an obvious gradation from dark blue to green.
Attaching some pictures. The rendering is not the best especially in the darkness, but the issue remains clearly visible.
There is something very wrong with your screen. Return it.

I second that, that is not normal
I concur with the others, get it replaced.
AMOLED screens can fail for any number of reasons (pixel death is the main one) , if yours is showing problems get it replaced now rather than live with it and have a more serious problem later.
We've seen this yellow color issue reported by a few others. Looks like Samsung let a few diseased horses out of the barn. I concur with the others. Return it.
Thanks for your feedback, guys.
I'd like to highlight the fact this issue goes completely unnoticed in most scenarios. A friend I showed it on white background didn't notice it at all, in movies/games/pictures I don't see it at all. I only felt it while reading, and even then it was not obvious, just a persistant feeling that led me to further testing.
Only the extremely dark colors seem to be affected, and even then it's only noticeable in the darkness. I will go back to the store tomorow and exchange it for a new one, but I'm wondering if the issue isn't widespread and simply went under the radar as its effect is hardly noticeable in 99.9% of the situations.
Did anyone else check at an homogenous R:0, G:10, B:20 image in the darkness with their tab ?
I personnally used Moon+ Reader's background color settings for testing purpose, pretty easy to set up.
New Tab S, same issue
I changed my Tab S 8.4 today for a brand new one. Same test, same issue: the background is still not homogeneous. The issue is visible in the darkness on dark colors such as the one used for the settings menu, which seems naturally gradated from deep to lighter blue on my screen.
Could someone else test and reproduce the issue on their tab ?
I have tried to reproduce what you're seeing on my 10.5 and honestly I can't. I'm not going to say the white is always 100% pure white but it's close enough. At the same time I'm trying to avoid looking for something that's not there for my Tab.

Maybe you can go into Settings / Accessibility / Vision / Color Adjustments and see if your calibration is off. There is a test there where you arrange tiles by color gradation and it adjusts your screen. I am having none of the issues you mentioned, but my 10.5 Tab also passed that test with no color adjustments required. Give it a try.

Test completed successfully. The calibration is fine, and the issue is not noticeable during the test. The issue is actually not noticeable in most usages, I only see it on homogenous very dark color backgrounds (the 10% darkest colors), and while in a dark environment myself. In most common usages, the screen looks fantastic and flawless.
Unfortunately, I often use my toys in my bed in the darkness. AND I am concerned about a possible defect that would get worse over time.
That said, tests on similar colored backgrounds on other AMOLED screens (PS Vita, Galaxy SII) lead me to think this could be a global issue with AMOLED.

Lol, to those of us with a perverse sense of humor we would refer to that as a hanging curveball.
Whatever issues you are experiencing I would take that over LCD light bleed any day.

Dear Friend. Like you I am very sensible in that point. I have a lot behind me and I can tell you, that homogeneity is something we can not expect from all types of modern displays, except the pro ones with a special function that takes care about this issue. Any screen has such issues, the question is just what type of and the intensity differs. The lower the light in our environment the more sensible our eyes get. The longer we stare into the screen the better we see all color details. Worst case scenario is a totally darkened room. Your eyes won´t get more sensible than in such a situation. Especially AMOLED displays will show the strangest kind of irregularities you would never see normally. I remember the Tab 7.7 -- in a dark room the screen was over and over covered with black circles. Wow ! The Vita shows strange textures instead. It is horrible.
My advice to you would be to start trying to avoid using your tablet or any display in a dark room. Turn a light on, it will be nice for your brain and eyes and you will not see the described things. It´s just a matter of habit, nothing else. You will get used to it and probably feel very well with it. Anyway there will still be the green haze.... Not to talk about the yellowish etc. stuff.
I returned the Tab S for a MiPad and it´s much better, really nice homogeneity (compared to other actual devices).
I had 4-5 iPad Mini Retina and all of them have horrible yellowish/blueish tint.
I had 4 iPad Airs, 3 were horrible in a similar way, now the 4th one is okay, I finally had luck.
I had 2 Galaxy 12.2 - the first one yellowish in a quarter, the second has just a slight, short yellow stripe on the bottom border.
I had a Kindle Fire HD + HDX - both with bad, ugly green spots at borders and corners. Also partially yellowish.
Once I held a Galaxy Tab 3 in my hands that was actually flawless. I was shocked. It never happened again. Was from a classmate.
Today I guess it was a mistake since I could not test in in a home-at-night-environment.
I checked dozens of Tablets in big stores here - guess what I found ???
Look at the iMacs .... Horrible yellowish tint. Horrible. It´s a shame.
I use my Tab S 10.5 in a dark room with some regularity. I've never experienced any of these odd artifacts you guys are discussing. My black screen is just black. Colors look right. White is white. I think its a fallacy to claim that all amoled screens face these issues. The amoled screen on the Tab S is the best most advanced amoled screen ever created. Problems from older devices shouldn't apply here.
Please remember based upon other user input, Samsung did seem to have a run of defective screens on these tabs they put out.
Here's a quick video test taken in a pretty dark room (it's daytime here). As you can see the screen is just black. There is absolutely no reason to avoid viewing your Tab S in a dark room. If you are not seeing the solid black I have demonstrated in this video I suggest exchanging your possibly defective unit.

In my experience 100% of AMOLED displays exhibit this behaviour, i.e. both Tab S 8.4 I've had! The first one (exchanged because of unhappy whites) had it so obviously that it looked like a diagonal gradient fade to one corner. The second tablet shows it as a slightly patchy screen, see attached photo which looks worse than the reality.
This is only visible in a completely dark room with the display set to its darkest (or close to), displaying a very dark image (my photo is of the spec. you mentioned - hence blue/green colour). To show this I needed to use an exposure of about 1 second, if you use less the image will appear black, likewise (probably) if you try to capture it as a video using normal ISO values in camera, the camera won't pick up the background.

All I can say is that is seriously messed up. My screen looks nothing like that and just as pitch black as in my video. Considering black pixels in amoled screens are basically turned off, they should be utterly and completely black and devoid of light. Am I misunderstanding and your picture is of a blue background?
All other dark colors should be solid without strange light effects as well.

It's daytime for me at the moment but yes from memory, if you display an actual black image then it will appear as black, you see this effect when trying to display an image that is almost black, at very low levels of light output the (my!) panel isn't even.
The attached image is R0 G10 B20 and on my PC looks black - it isn't I just used "ColorPic" to check the screen colour and it shows those values.
It's not a big issue but does appear when using in fully dark room with brightness turned down, I notice it in some apps that have very dark background colours (which you'd assume were black and see as such in daylight, but aren't).
Obviously under these circumstances an LCD would appear as a (relatively) bright grey !

Same on my tab in daylight, it only appears patchy when in a very dark room with brightness turned right down. Maybe amongst the variations some will be perfect?

I currently have a tablet z and I am wondering how does this compares to Tab S 8.4.
I am thinking about buying this one on account of the superb screen but seems that there are a great deal of lag happening, is it so?

This is by no means the fastest tablet out there. Though I love the screen and my aosp ROM is working better everyday and has eliminated any lag issues I had.

I can't compare with the tablet Z, but I own a Tab S 8.4, a Nexus 7 2013 and a Note 8.0. I will try to answer your questions based on my experience:
The tab S 8.4's screen is a huge disappointment to me. It looks awesome in bright environments, the high pitch and vivid colors are pleasant to my eyes. However, for someone with high expectations as I did, it suffers from several issues that used affect previous AMOLED generations and totally ruin my experience:
- Smearing on black backgrounds. An issue that was already reported on Galaxy S4, and that seem to affect Tab S 8.4 as well: A dark red smear is visible when watching movies on black backgrounds. It looks like black pixels are slower at displaying a color than already lit pixels. The result is not obvious on first watch, but once noticed becomes a nightmare in dark movies.
Here is a fix for this issue: http://forum.xda-developers.com/showthread.php?t=2259775
While this seem to be pretty efficient fixing the smearing issue, the result is not perfect, it is rather annoying to use AND we lose the benefits of perfect blacks in the darkness. And it impacts battrery life, as a dark grey pixel is powered, while a black one is not.
- Mura effect. Basically, dark (but not black) colors are not homogenous on the screen. It is only really noticeable in the darkness, wich is my main usage for the tablet. Rather annoying, especially since the fix for the smearing issues induces replacing all "black" by "extremely dark grey", which reveal this issue.
More information on mura effect: http://forum.xda-developers.com/showthread.php?t=2108073
- Yellow/greyish tint. This one is'nt the worst, but can be felt on white backgrounds. This one becomes obvious when compared directly to a more natural white screen: the middle of the screen seems more yellowish and darker than the borders. It seems like the glass could be dirty, or tinted by years of heavy usage, which it is not.
None of these issues are obvious to someone who doesn't set his standards very high. They are for me though, and will probably be noticed by people willing to use the tablet in the darkness.
As a bottomline, I actually prefer the display offered by my Nexus 7 or iPad mini retina rather than the Tab S 8.4's. They lack the "wow" effect of vivid colors and the perfect blacks, but provide a more homogenous experience, especially in the darkness.
Now for the performances, I don't know what's wrong with this tab. I was thinking about putting the blame on TouchWiz, but alternative launchers don't help. Rooting and turning off as many services as possible didn't either. Here is what I noticed:
- System zoom effects are subjects to stuttering (opening new app/window, for example). None of my other android device suffers from similar issues, and zooming in other apps such as web browser works flawlessly. The issue is not reliable, and seems to reduce when the same window is opened and closed several times in a row. Memory access issue causing stuttering ?
- Overall system doesn't feel as smooth as it should. Even my elder Note 8.0 feels butter smooth compared to the Tab S 8.4, which I can hardly explain. It is fast enough, but the FPS seems to be lower.
- Two of my favourite apps suffer from low FPS when scrolling: Perfect Viewer and Moon+ Reader. The poor performances make the experience with these apps less enjoyable than on N7 or Note 8, which his hard to explain considering how much more powerful the Tab S 8.4 should be.
- 3D gaming is not at its best either. Performances are clearly below N7, and maybe even lower than on Note 8. There, I guess this is the cost for the extreme pixel density of the display panel.
If you are satisfied with the services offered by your Sony tablet, I'd suggest to stick with it. The Tab S 8.4 is a very decent tablet but not perfect, and its major strenghts are also its main weaknesses.
My 10.5 tablet doubtlessly has the best screen I've ever seen on any device. Sure, a k1 is faster CPU and GPU wise, but for my mainly media consumption and Web browsing it's amazing. Haven't experienced any of the issues mentioned above so I guess pentile does detract a bit.

Your answer was perfect for my needs as my main utility for Tab S would be perfect viewer and moon reader as well.
Reading all sorts of experiences I'm beginning to wonder if I should buy a new tablet or not and it seems that I will rain check this purchase for now...

since in some country you can like send it back if you not satisfy kind of sale.. and if it apply to you why dont you test it. i dont have any problem like being mentioned above. and in this short period... i think the QC of the device are kind of loopy... some got great functionality without any problem and sadly some does.

Regarding the screen, I couldn't find reports about the issues I mentioned above for the Tab S 10.5. It looks like the screen on the 10.5 is using a newer technology that would fixe these issues. I so wish it would be the same for 8.4 !
Not everybody is noticing these issues on 8.4, but then I believe it to be related to lower sensitivity to the issues. They are not obvious at all, and basically impossible to notice in lightened environments and/or watching colored images.

As a newb at flashing roms, I didn't go further than rooting at the moment.
Regarding the screen, while I am surprised that people report not noticing the issues at all, I am convinced many just don't notice them.
The smearing is actually more felt, guessed than seen. But once noticed, it becomes an annoyance.
The green/yellow tint is only visible on white backgrounds and when comparing to other screens or looking at it for a duration (reading e-books or internet webpages). It's far from being obvious on first sight.
The Mura effect however should become obvious to anyone looking for it. You can try with the follwing steps:
- Download and install screen adjuster.
- Get in the complete darkness
- Launch Screen adjuster, and set Red, Green and Blue to +5. Make sure it's switched on
- Look at a completely black background
=> The black background won't be black anymore but very dark grey. This is what Screen adjuster did by adding +5 in each color. If the screen is affected by mura effect, some areas will be lighter grey and others darker.
This is an issue that affects the 3 tab S 8.4 I tried (I exchanged it twice), as well as my Galaxy SII and my PS Vita. I just wish it wouldn't be the case, but I have yet to see an amoled display that isn't affected, and can hardly beleive I would be cursed badly enough to always get faulty units.
No issues on mine. The screen is superlative!

I've already tested mine T800 for mura with many shades of grey and no issues found.

Yes, from my readings here and there, T800 screens whouldn't suffer from the same issues. They use a different technology though, I wish T700 would be using the same.
yes. me too.
"ukael" is right.
I had this problem on my both two Samsung Tab S 8.4 LTE T705.
on first I thought it is related to that one, but after purchased 2nd Tab S 8.4 T705, I noticed screen going yellowish.
specially in middle screen while in horizontal rotate specially reading something that has white background.
