Screen and Backlight quality?

Hello,
The display has a great resolution and has a wonderful size, but what can we expect from the screen brightness and contrast?
There is a review where the HD is compared to the Iphone 3G and the contrast and brightness of the iphone is even better (colors are stronger). Will the sold blackstone offer a better quality display contrast / brightness?
thx for any reply.

It's not the screen itself in which the IPhone is superior. Both screens (in darker situations) have quite similar brightness/contrast/color strength (looking at the Diamond and an IPhone 3G right now), and the Diamond is a hell of a lot sharper with 3 times the PPI.
But outside, on pictures and in well lit videos, the screen of the Diamond, Pro and HD all become a bit glared because they do not reflect all of the light, like the IPhone's glass screen, or the Blackberry Bold. They pick up some of the light which makes it harder to view the screen which is behind the top plastic layer, hence it looks as if their contrast is worse than that of the IPhone, which is not always the case.

In terms of DPI/PPI the HD will be lower than the Pro/Diamond I'm assuming since the horizontal resolution is the same even though the screen is wider and the vertical resolution is 'only' 160 pixels more in a screen that is a good bit longer than the Pro/Diamond.
Is this 'loss' of DPI/PPI in any way noticeable?

It is noticable, as soon as you stick your face into the screen and have good eyes The PPI is lower yes, but still much higher than say the IPhone (about 2.5 times higher). Since even on the IPhone you hardly notice pixels, the HD screen will still be tight as a drum, print quality for sure. The difference between the HD and the Diamond really is minimal.
Also, the huge screen means you will not be staring at your phone from up close since you have so much more real estate, you can hold it further away. Also I like the fact that the PPI have decreased in the width, because that makes all WinMo user interface bigger which is a plus imo, I really like the Diamond but their statement that you will only need one finger to control everything is BS.

[Q] Dell AMOLED vs HTC HD7 LCD?

Everyone has been raving on the DVP's screen, but having had the HD7 while waiting for my DVP to arrive, I've gotta say - I have mixed emotions!
While the colors are substantially better side by side...anyone notice how pixelated the DVP's screen is on text and such? The battery indicator is a good example of what I'm talking about...
I think I might actually prefer the LCD of the HD7 better, despite the lesser black level and color saturation.
Anyone else have any thoughts?

I see what you are talking about... I didn't realize this before you mentioned.
AMOLED in VP is a little bit too much saturated and the HD7 is a wee bit too washed up
A middle ground would have been awesome.
Maybe SLCD or SAMOELD hits that middle ground. My friend is getting the Captivate, will compare this side by side and let you know.

I have a slight blue tint on my whites at certain angles. I dont see a big difference in the two screens, but i expected more from the AMOLED.

I think that was my big let-down. I had (probably overinflated) high expectations of the AMOLED. I didn't see much on the net talking about it, and in fact, most reviews talk about the sharpness of the display, so I was confused if it was just my unit?
I *WAS* able to find a couple of sites that talk about AMOLED having sub-pixels vs a standard LCD/SLCD, and therefore it's not as good for small text or sharpness...
I must say, though, I love the keyboard, and I'm still going to keep the DVP over the HD7 - just a little surprised at the lack of impact from the screen, considering what they've done to build this device (gorilla glass, etc).

I agree with you on the fact that the AMOLED on the dvp has noticeable pixels more than the HD2 that I have. What’s even more sad is that they have the same resolution yet HD2 has a larger screen – Thus I should see more pixels from the HD2, however, this is the opposite.
Why does the DVP have noticeable pixels? Can anyone compare this with the Nexus One and see if they are the same?

Pen-tile matrix effect, probably what you are seeing here. However I cant see what scenario would occur to make me prefer the washed out screen of the HD7, just too darn low quality for me.

Its the nature of the AMOLED screens, my Focus had the same thing. However, overall, I find the screen on the DVP far, far superior to the HD7.

it was my understanding this is more a fault with windows phone 7 as it does not use 16m colours like the display can do.

Personally owning both.. the DVP has a MUCH better screen. Especailly if you change brightness to high.

ive never see an amoled screen before, but coming from the HD2, i was very disappointed.
i guess the hype of amoled screens made me have high expectations which were too high by the time i saw a real amoled screen.

Now that I have a DVP in hand all I can say is the difference is clear, the Dell's AMOLED screen is superior. Maybe some are being swayed by the size but for someone who has had an HD2 for almost 9 months the size is not really a factor and the lack of colour, dim lifeless screen is just no competition for the AMOLED on the Dell.

HD7 Advantages
+Noticeable advantage in color accuracy
+Larger screen offers better spacing on keyboard (portrait)
+Good black levels while inside optimum viewing angles
+/-Brightness is more than adequate (auto brightness is a little conservative though)
+/-Decent viewing angles (No issues during regular use)
HD7 disadvantages
-/+Decent viewing angles (Poor viewing angles make kickstand less useful)
-Slightly less responsive (my opinion)
-Lacks sharpness while viewing pictures (not sure why but they aren't as sharp as the rest of the time with the HD7)
-Color saturation could be better
Venue Pro Advantages
+Excellent contrast with fantastic black levels
+Slightly more responsive touchscreen (my opinion)
+Good brightness
+Excellent color saturation (somewhat oversaturated though)
+Perfect size (my opinion)
+/-Sharpness (pixels aren't noticeable during normal use)
Venue Pro Disadvantages
-/+Sharpness (some users may notice more pixelation)
-Very high color temperature (extremely unusual coming from a calibrated display)
-Can't use the brightness to your advantage without battery drain
-Keyboard felt a little cramped coming from the HD7
I miss the color accuracy of the HD7 but love the size and responsiveness of the Venue Pro. The HD7 gets a bad reputation because of viewing angles but during normal use this is a non-issue and possible advantage with curious onlookers (there will be plenty). It offers better black levels and shadow detail than the iphone 4 but gets hammered for viewing angles. The Venue Pro offers fantastic build quality, an almost perfect size (my opinion) and a more responsive touchscreen (my opinion). It has a very high color temperature but offers superb black levels and color saturation. It is also sleeker than I had anticipated from all the comments saying that it is a beast.

Sorry for the double post

Samsung has bastardized AMOLED with pentile imo. It prolongs display life but the tradeoff in picture quality is too great. There are AMOLED's with normal subpixels, and they look fantastic (Cowon S9, Zune HD, etc).

That's a great point - the ZuneHD I have looks amazing! Still loving my phone, though...

Zoom Sharpness?
I purchased the DVP to have something that will show my pictures a little more accurately than the LCD I have on my HD2 (the slightly extra saturation is better than the washed out look on the HD2) but I now find that there is no sharpness to the images when zooming in.
I have a photo of the lights of Chicago at night and when at the full screen zoom level, it looks ok but zoom in and it is a blurry mess. My HD2 is very sharp when zoomed.
In the Zune software I have tried full size pictures compressed by Zune, pre-compressed images with Zune left on "Original" with no compression and nothing seems to make the images better when zoomed.
Anyone else seeing this problem? This could be a deal breaker for me as far as AMOLED screens go unless it is a WP7 problem. I would love to see how my images look on a Droid device with AMOLED.

I agree with you. Images seem way too pixilated. I mean, I can actually see them which is so sad when I compare it to the HD2. When I am going to do is wait for WP7 to be release on the HD2 by Cotulla and then compare if it the OS or specifically the DVP.
Has anyone seen another amoled screen before in real life? This is my first time I’ve seen an amoled screen. I am not impressed…. At all. Lol but the colors are lovely. Image quality drops, while color saturation grains points

If you read the Cnet phone screen shootout you will see that the HD7 has some pixelation on images of text when zoomed. I have also seen some softness and pixelation on my wifes HD7 when zoomed in. This only really seems to be when viewing images so I would guess it is OS related and not specific to the Venue Pro.

I own a Nexus S and DVP and the dell is getting returned today. Main reason is android is a better fit for me but close second is NS screen is head and shoulders better. No pixelation like I had on dvp.
I think I had a lemon too my dvp was freezing quite a bit.

I find this odd. I had a Focus and an Epic 4G - both have the same screen as the Nexus S - and they had the same pixelation issue as the DVP. It has to do with the AMOLED screen.

HTC One Display Colorimeter test

I know a lot of you are looking for some display calibration test of the HTC One.
I have found a good review but it is in Dutch, although well translated by google.
http://translate.google.nl/translat...et-kleine-imperfecties-het-scherm-getest.html
in short: It is a great display, best 1080p phone display. The colors on the One X are better though.

Something must have gone wrong in the Color Temperature test. They indicate that the display would have an even bluer tint than the Galaxy S3. I find that hard to believe after all the accolades this screen has been getting and just by how blue the whites are on the Galaxy S3.

This test is a joke, one x is much brightrr than the one lol, one have 370 nits from engadget and 6 other sites but here it has 480?
Close this thread mods

The One is a lot more brighter than the One X+

The HTC One X had screen of 3 different manufacturers and all 3 had different brightnesses and color values.
Same thing going on here.

I'm judging only by eye, but I'd say the level of blue-push on my One is pretty much in line with what they found in that dutch review. You notice it a lot in videos - skin-tones aren't quite right, and everything feels slightly too cold and grey. It's possible that I and the dutch reviewers both have faulty handsets, I suppose.
It's also possible that most people don't know blue-push when they see it! Most televisions are calibrated with white points way into the blue if you use out-of-the-box settings, and relatively few people even bother to change the colour balance to "warm 2" rather than "normal", so significant blue-push is what a lot of people are used to and have come to expect. And the TV manufacturers use those out-of-the-box settings because they are designed to appeal to people at a quick glance on the showroom floor - blueish whites, over-saturated colours and exaggerated contrast and sharpness. People clearly like those things: look how many reviewers think the Xperia Z looks better with Bravia switched on. (Personally I find Bravia colours so unrealistic I feel like my eyes are going to start bleeding).

With the One X there were 2 versions for the European market. A Sharp screen and an Acer one. The Sharp one was much brighter than the Acer which might give rise to the confusion as to which phones are brighter. The Acer had better colour accuracy although HTC did improve further the accuracy for BOTH screen types in a firmware update. The One X+ I believe has the same Acer screen as the One X. There was some rumour that it was different but I had a One X (Acer) and One X+ side by side and they were clearly the same screen type.
So the good news is that HTC can improve it if they are all out by the same amount. If they vary wildly betwen units even with the same screen type then we are screwed.
I can see my One is a bit on the blue side but it is MUCH better than my S3. It is only a bit into blue, not wildly on the One. Also the screen is SO uniform! Maybe I just got lucky with that. How are others finding uniformity across the screen? NO backlight bleed at all, zero.

Variations in screen origin might perhaps account for the wildly differing numbers in the Dutch review (tweakers.net) and an earlier Russian preview (which you can find here).
It's also possible that all the positive reviews of the screen are based on the same pre-production version that the Russian reviewers saw, and that the version on the retail model is less accurate than the one on the review models, and has performance in line with the Dutch numbers.
It's a bloody minefield, this, isn't it?
What we really need is some more people doing colorimeter analyses. Sadly, I haven't owned a working colorimeter for a while now. If someone would like to buy me one, I'll take it for a spin.

keep in mind HTC have history of re-calibrating their displays with OTAs, it takes a few of the early OTAs before settling
although i keep wishing they should also offer color profiles like Samsung
knowing HTC the answer would be "the average smartphone user will not bother to change it"

Sony Xperia Z5 vs Samsung Note 4

Hey guys,
I am thinking of buying one of this mobiles. They both seems very good, got 3GB of RAM, big display (i want some bigger phone), but.... I am wondering which one have better display and which one got better battery. This is probably the most important for me.
If someone have more experience and use some of this i would appreciate your thinking.
Thanks in advance.

Note 4
Luckily for you, I've owned both phones since the month each got released.
Note 4:
Pros- bigger battery ( I've noticed slightly longer battery life)
- outstanding screen
- Pen
- Removable battery
- dont need to turn off phone to remove micro sd
- Ir blaster
- plethora of cases/accessories
Cons:
- Phone sometimes feels cumbersome to use
- Touchwiz sucks
Xperia z5
Pros:
- Sexy as hell
- Waterproof
- Normal screen size
- Camera button
Cons:
- Back gets warm pretty quick
- Doesn't have any of the pros listed for note 4
------------------------------------
Get the note. Every time I use my note 4 for something I notice how much crisper the screen is, and I hate not having that on the Xperia. Samsung did a really good job packing a ton of features in the note 4 and the screen will keep it future-proof longer than the Xperia. I actually prefer the note 4 to note 5. ( buy the unlocked version and install note 5 rom on it, you'll get the note 4's removable back + new software)

I also owned both and I should say Z5 screen is way superior to note 4.at least mine.I still have note 4 and can answer questions if you have any.
PS:note is easier to root and flash CM if you care.I had to return my Z5 because of lack of root for locked BL.I'm back to my Z2 and N4 is collecting dust.lol.

RE
Man,
Thanks a lot for this brief.
I always think that Sony have better display, probably because I am a big fan of Sony. But now when I see that Note wins bots display and battery I will for sure go for Note 4.
Just one more thing, because i am not that kind good with android and software. When you installed new custom rom to Note 4 you had no bugs or something like that? I found on forums that it can be very bad doing this so i need your opinion?
Thanks in advance!

Lol, comparing an OLED display vs any LCD display and pretending that LCDS can be on par or better than OLED displays is so dillusional its actually funny!
I would still choose Z5 but for different reasons: 1 performance, note 4 has a weaker cpu and gpu, z5 camera is more sophisticated than note 4 camera except z5 camera has no OIS and lacks several manual functions, but me and many others can live with that, Z5 has real radio, Z5 has water proof support and z5 has dedicated camera button.

Re
So many different opinions.
@ TheWarKeeper
Can you please tell me your experience with battery. I need it for my job and i am using a lot of calls, email-s, social networks.... Can it last at least one day.

It's not black and white. LCDs can and tend to be able to display proper white (sometimes you need to tweak it via white balance settings but YOU can have it unlike OLEDs) while OLEDs tend to have difficulty with it and never truly achieves proper whites and you have to calibrate with time due to OLEDs organic nature. But in contrary OLEDs displays deep blacks due to switching of the organic pixel (LCDs cant switch of becouse the R G B channels are just filters on top of the backlight). White is more important though as that is what is used most in apps, themes and so on. And due to the OLED being organic the blue, red and green pixel component each have a life length and blue has less than the other 2 which means having bright/white things displayed on your OLED would shorten the blue components life length faster resulting in uneven colors on the screen, "burn-ins" and it just gets worse with time.
LCDs dont have this problem becouse the only thing you lose with time is the brightness due to the backlight getting worn and so you can compensate by increasing brightness intensity. And Sony TFT and IPS LCD for their Z1+ lineup comes with Triluminos which adds an extra component to help the pixels and extends the color range to 85% of Adobe RGB 1998 ICC color profile which is far more than a regular LCD can do giving rich and accurate colors that without problems rivals OLEDs while still being proper and true to life without typical OLED oversaturation. Triluminos also helps with the black but cant rival OLEDs 'pixel switching off' blacks.
Now latest OLEDs from Samsung does better than older but they still tend to oversaturate since they also can display beyond standard sRGB color scheme that is the standard but cant really accomodate to it like an LCD with Triluminos can due to its organic nature and how it works.
You want precision that holds for years and proper white you go with Z5 but if you want deep blacks, "popping" colors and less precision you go with OLED. OLEDs also have better response time but that would mostly only be of importance if you play games at fast framerates.

In my opinion, you should also consider the UI of Samsung and Sony because TouchWiz (Samsung UI) is notorious for lagging as months passed by and when multitasking, while Sony UI is always smooth and rarely lags. :good:

I had a Note 4 before getting a Z5P. Stock Samsung is garbage. You have to look into AOSP/CM for the Note 4 and it may not be 100% stable. The Note 4's camera is definitely though. Z5 camera is only good on paper but in real world situation Note 4 wins easily. Z5 has way too many pixels can't produce a good image unless the source is extremely well lit.

The problems with white balance for oled displays are long gone, those issues were only present in the first few oled screens ever produced because back then the organic material for red and green were degrading at a different level than the blue.
My Galaxy S6 has the purest white any LCD dreams of and also a much bigger color gamut, also it has a fraction of the pixel response time of any gaming tft lcd out there producing less ghosting and blurring when in motion, on top of the pure blacks as you acknowledged also.
As for the over saturation, the oversaturation comes by default to boast the contrast capabilities of the oled screens, normally found in test units, my galaxy s6 for example came out of the box with such a toned down saturation that nobody would even dare to call it an OLED, but anytime i want to enable eye popping colours i just change the color scheme from the display settings itself.
Theres no reason to vote for a LCD anymore, except if you are concered about buying a monitor/tv thats always ON and not bothered with image quality, then LCD is best as it doesnt suffer from burn in issues, or color degradation, but frankly thats just about it.
EDIT: i also forgot to mention that the best LCD screen ive ever come across in any phone was the Xperia Z1 Compact screen, perfect color reproduction at everything, which put Xperia Z2, Xperia Z3 (both normal and compact) and Xperia Z5(Again, both normal and compact) screens to shame.
So for me the Xperia Z5 screens are dissapointing and white balance by default is over the top, too much RED, to calibrate it properly youll loose other screen abilities.

The phone should last a day as long as you dont push it and dont enable brightness to maximum all the time.
If it doesnt well, you can always get a pocket charger as the competition of z5 will last only a slightly more time which is negligible.
I would choose the Xperia Z5 over the note 4 anyday though, its a great phone and it wont dissapoint any average user.
Xperia Z5 only dissapoints enthusiasts like myself but not because of its quality, quality is great, but because of DRM and locked features which makes no sense beying locked.

What are you guys talking about? Note 4 has one of the best screens on the market. Near perfect white balance (6562K) and 99% Adobe RGB. Just use Photo Mode. Adaptive Display mode is over saturated but optional.
http://www.displaymate.com/Galaxy_Note4_ShootOut_1.htm
Also color burn is an old issue from Galaxy Nexus devices and earlier. Samsung displays have burn-in protection.
Moving from Note 4 to Z5P was definitely a downgrade in color accuracy and white balance, but upgrade in pixels. I honestly thought I would care more, but I actually don't. I rather have no screen door effect in VR and higher resolution. Now if Samsung released a 4K AMOLED screen...

Interesting. So kind of cheating for tests/demoing regarding readability as you cant have both maximum readability and accurate colors.

The highlighted part goes against your first comment. All 3 color channels degrade independantly of each other based on what is displayed and how colors are used. Blue is still used the most.

I have not tunned the Z5c LCD but it does actually for my unit use to much blue. Though my Z1 has near perfect white balance with minimal tweaks aswell as boosting impressive contrast, top notch color reproduction and good viewing angles. For being a TFT LCD with Triluminos it is quite close to IPS LCD regarding viewing angles except when brightness on displayed material goes above a certain threshold but immensly better than a regular TFT LCD. I have a JDI panel btw.
So for me the Xperia Z5 screens are dissapointing and white balance by default is over the top, too much RED, to calibrate it properly youll loose other screen abilities.

Strangely enough it either goes for to much red or blue. Maybe panels come with different "qualities" and/or different assembly fabrics and quality. As long as you dont have to 'mute' a color channel to much to get good whites it should be OK else you lose brightness and contrast.

The camera is really bad in real world situations. Despite what you read in reviews that only test extremely bright or extremely dark environments, taking photos at home or indoors is pointless. People's faces will look like they were smeared with peanut butter. http://imgur.com/0OhbSaq
It performs worse http://imgur.com/Pfd76nR than my Note 4 http://i.imgur.com/wOvr0kl.png in indoor lighting, which means the camera was a straight-up downgrade for me. I don't bother trying to take pictures unless they're daylight or I can use flash which, to make matters worse, is still extremely weak. This all seems like extremely crappy postprocessing smudging pixels together and there's no way to turn it off since there's no RAW support.

It performs worse http://imgur.com/Pfd76nR than my Note 4 http://i.imgur.com/wOvr0kl.png in indoor lighting, which means the camera was a straight-up downgrade for me. I don't bother trying to take pictures unless they're daylight or I can use flash which, to make matters worse, is still extremely weak. This all seems like extremely crappy postprocessing smudging pixels together and there's no way to turn it off since there's no RAW support.

I own the Z5c and cant relate to what you are sayinh although it sure needs some white balance and algorithm tweaking. In your photo comparision it looks like the Z5 photo was taken with zoom and possibly older firmware vs just a crop from the Note 4. Without ISO and shutter speed info it's also quite pointless "comparision". Exif would show it zoom was used and much more. I can say though that not even with ISO 6400 in low light does my Z5c produce such bad image quality. Only with zoom.
And the test I linked to is properly done with information and different scenes with different lighting conditions unlinke the "tests" by random people on the interwebs posting photos without exif data nor information and croppings where you have no orignal fullsize photo as reference either. Who has more credibility, that test or your "test"? Anyway it's pretty much settled in stone that the Z5 is better.

And you missed the point...
The point is, these are real world samples. The first shot was me at a wedding. Yeah, it's zoomed, but not the point. The point is the heavy smearing of pixels the post processor does, ruining the quality, just because to Sony all noise is bad.
The second was my Note 4 and Z5P both taking a picture at the exact same distance of something I have at home in dim lighting. The Z5 is straight up worst and if you can't see that, that's some serious " fanboyism" there. And yeah, my Z5P running 6.200, so no, it's not an "older firmware." You don't need EXIF data to see the point I'm making. In dim lighting, the Z5 severely underperforms. But you rather believe my sharing of these photos is part of some conspiracy to maliciously fake a comparison so the Note 4 is better go right ahead.

They still suffer from uneven colors and shades over the display.
The whites are though life dependant and Triluminos widens the color gamut to 85% of Adobe RGB 1998 ICC profile.
Interesting. So kind of cheating for tests/demoing regarding readability as you cant have both maximum readability and accurate colors.
The highlighted part goes against your first comment. All 3 color channels degrade independantly of each other based on what is displayed and how colors are used. Blue is still used the most.
I have not tunned the Z5c LCD but it does actually for my unit use to much blue. Though my Z1 has near perfect white balance with minimal tweaks aswell as boosting impressive contrast, top notch color reproduction and good viewing angles. For being a TFT LCD with Triluminos it is quite close to IPS LCD regarding viewing angles except when brightness on displayed material goes above a certain threshold but immensly better than a regular TFT LCD. I have a JDI panel btw.
Strangely enough it either goes for to much red or blue. Maybe panels come with different "qualities" and/or different assembly fabrics and quality. As long as you dont have to 'mute' a color channel to much to get good whites it should be OK else you lose brightness and contrast.

Ok well it makes me think that you didnt own a proper OLED phone, maybe you did own a bad one in the past and the screen was crap (defective).
First of all, OLED screens do not result in color saturation shift when degrading because the software inside their panel drivers automatically correct the color shifting, (my galaxy s2 still has top notch colors).
As for the cheating, i have no idea what you mean by that, you can saturate the colors or desaturate them at your will, i dont know what cheating is involved because there isnt any cheating at all xD
I have tuned my Xperia Z5 screen and i had to keep red to minimum and blue and green almost to max to get a proper white balance, doing so, resulted in severly desaturated colors and bad luminosity (as the panel software disallows maximum brightness values when colors are calibrated).
I never liked the Xperia Z1 screen, a small tilt resulted in horrid washed out colors, Xperia Z1 Compact is a completely different beast with the best IPS panel ive ever seen in any phone 1800:1 contrast ratio (native)!
As for that complaint in the note 4 forums, its obvious that the user of that phone suffers from the typical defective screens that samsung fails to stop at production, uneven color or tints of any kind on the screen is not a characteristic of an oled screen, its a characteristic of a defective unit, i have to change 2 galaxy s6 untill i got 1 with perfect colours, i had to change 1 galaxy s2 to get the good screen and the galaxy s4 i got it with perfect color reproduction from start.
Finally, LCD screens were always the worst type of screens in term of image quality and color fidelity, even at professional image editing level which means wasting thousands of dollars on a proper IPS LCD screen, professionals were never really satisfied with its color reproduction and instead choose to use old school CRT monitors (myself included).
The only reasons why LCDs are successfull is because of good marketing, they suck at color accuracy, they suck at pixel response time and they suck at image definition. (My OLD Sony CRT ran 75hertz at 2048x1536)
It was a joy to use in any type of situation, movies, playing games and image editing software.

You still lose luminosty and or/color representation quality when correcting the other channels to lowest common denominator uniformly. S2, S3 and played with S4 and S5. The former ones wher just horrible. You could almost spot the pentile matrix design and colors overly saturated. "Eye bleeders"! :laugh:

You mean you had to set green and blue close to 255? That sounds like your screen is way off. I might look into mine later and see how much it needs to be tweaked via the white balance setting.

Well then that was the AUO panel. They made an ugly one by having different panels. I got the good one, JDI and I can tilt it and have very close results to that of an IPS LCD as long as the displayed graphics aint overly bright (lots of white) where it then performs worse but then I am talking about extreme viewing angles. Btw OLED also looses quality when tilting at sides and has 'color switching' and black suffers (if pixels aint switched off).

Still better than having uneven colors and blotches. Nothing worse than having a display that looks like a CRT that has been abused with a magnet (not as bad though but still!).

Right.. 3 on a row, 5 on a row, most/all retail store display units.. Then going by what you say Samsung has horrible QA for their OLED displays and you are in for a ride in the lottery. Tons of people in the 95 page thread going through multiple units all with the pink/green blotches with varying severity. Pretty few getting a rplacement display that has none. All showing some color hues and some reporting it going worse by time. You even got a video showing differences in white point color to at same display color settings!
I even checked at local mobile phone store and S6, Note 5 units had color blotches on a white background. Some better some worse but still there.
Just Google it.

Great Phone, same old AMOLED problems.

I'm about done with AMOLED panels and I'm about done with the S7 because of it. Ever since phones went quad HD (Turbo, S6, Nexus 6, Turbo 2, Note 5, 6P, S7, etc), this has been a problem, and unfortunately it still seems to exist on the S7. This is my second one - the first one had it in a different area on the screen and it was even worse. It's the pink fade on light or white backgrounds. Once you see it you can't unsee it. I'm sure some will come in here and say they can't see it. I noticed it looks all white at the right angle so if you're not seeing it, you might move your screen a bit. Also, the first image (the horizontal one) shows it the most b/c it has the subtle camera lines which make the fade even more obvious. Not sure if there's a point to this except to vent a bit and, I guess, see if anybody else has had this issue on theirs. Given that the screen is supposed to be one of the main selling points of this device, it's hard to keep it when I see the fade every time a lighter background comes up...
Honestly, I don't really see one benefit to having an AMOLED panel any more - even the highest quality ones eventually deal with burn-in, the battery life is not any better, and they have inconsistencies which are apparently just par for the course. #frustrated

Hmm my S7 doesn't have this effect at all angles and I don't think this is something with AMOLED displays. I think it's the new gorilla glass and the refractive properties of it. At some angles it looks blue and others pink but looking straight at the phone I don't see any weird hue just perfect white. The colours on the S7 display are the best for an AMOLED screen so far and I can say that since I work in a paint store and colour matching is my life.

I know what you're referring to with the refractive properties on Gorilla Glass 4 and this definitely isn't that. I'm even able to see the inconsistencies on darker backgrounds as well. I've uploaded two more photos, attached to this post. That's a solid dark grayish/blue background.

Pick your poison. With AMOLED you're going to get higher brightness, contrast and color saturation, but it will shift colors on whites with various viewing angles. With LCD you'll get colors that are less saturated but more stable and no true blacks (thus worse contrast), and it's brightness, contrast and saturation will all degrade at higher viewing angles.

AMOLED screens are also thinner and consume less energy.

I know, and I guess I shouldn't be surprised. Though I don't think we're talking about just color shifting at various viewing angles. This fade (and prior fades) appears to be "burned" in to the screen itself, and while differing angles help a bit, it doesn't change the problem.

I don't know - obviously that's subjective, but even my iPhone 5S is still just as readable in sunlight, and having inconsistencies in the screen appearance on a $700 device, to me anyway, is hard to justify for the sake of pure blacks.

Many will disagree, but this is why I still think the iPhone 6 Plus has the best display. I own an S7 Edge and while my screen colors are even with no pink tint, the entire display does have a bit of a green tint to the whites and I can occasionally make out horizontal lines where the brightness isn't perfectly even on grays and whites, especially noticeable when scrolling. My S7 Edge is about as good as I've seen any QHD AMOLED display, certainly much better than any of the S6s I owned, but it's still not perfect, and I would still prefer the display from the iPhone 6 Plus. To me, good, even, uniform whites are more important than perfect blacks because most of the things I do on my phone involve white backgrounds (web pages especially).

One thing I would like to point out that you are completely missing is the contrast, not only black-white but the colour contrast! This is another area where S7 screen is clearly superior than 6s plus or any other mobile lcd. You can verify that by viewing a colorful wallpaper side by side on both the screens. Another thing is colour accuracy and colour gamut in which S7 screen again comes on top.
Both types of screens obviously have their pros and cons but SAMOLED screens arguably do have more pros over lcds than cons imho!

Agree 100%. And at least the blacks on LCD's are consistent. They might not be "pure", but they are consistent unlike the whites in AMOLED.

You call it superior, I call it over-saturated (), even still on the latest and greatest. Don't get me wrong, they look nice and my eyes get used to it after awhile, but no matter what I do the S7's screen (and S6's, and Turbo's, etc.) feels "cartoonish" to me when navigating through the UI. Every time I go back to LCD from AMOLED my eyes feel a small sense of relief - almost like the contrast was too much. I know that's not the norm, so fortunately we have choices. But I love everything about the S7 except, ironically, its screen because of these inconsistencies. I simply shouldn't be seeing a fade from white to pinkish grey on an all-white background on a 2016 flagship.

Lol.. it would be a shame then if apple goes with amoled displays in future ?! Anyway you seem very clear about your preference of the display type so I'm not going to contest that, but I would say that lcd displays are not free from fault like amoleds and they do have issues like backlight bleeding, abnormal tints, non-uniformity issues, dead / stuck pixels etc.
BTW, I'm not here to preach about amoled or lcds, it's only my own experience with both the display types in the past. My experiences might vary from yours but I've always had them better with samoled screens than lcds.

I just bought a s7 flat 2 weeks ago and its my first AMOLED phone., i dont have any kind of color uniformity but i can see the strong blue tint in white when i look at the screen from an angle, and its really distracting me too much. I dont know if i go to warranty and they can fix it.

No, as that is the nature of the technology. When viewed at an angle, LCDs maintain color uniformity but lose saturation, brightness and contrast. AMOLEDs shift to blue green but maintain saturation, brightness and contrast. Refer to my post above (#4) and check out the picture.

I see it, and i aggree with you but, color shift is more disturbing then losing brightness. Its not affecting when using phone most times but whenever i use my phone with one hand and try to open notifications, blue tint is appearing and i really hate it. Actually iam in love with blacks of amoled screen, but this thing is driving me crazy. Maybe i am just too sensitive this color changes.
And btw, my father have a Galaxy A3, and it has exactly same blue tint on his phone too. I Think samsung should something to fix it for next Galaxy S. Its really annoying.

It has to do with the varying luminescence and longevity of the various colored pixels. AMOLEDs have been like that since the beginning and it won't be fixed by the next generation of devices. Once you get in the habit of keeping the phone perpendicular to your eyes, it's not so bothersome. Then you go back to an LCD and see that it looks so flat and dim and decide it's totally worth it.

Sorry, didn't mean to sound so dogmatic. I really don't dislike AMOLEDs, the imperfections just frustrate me on such a high end device. You're exactly right that LCD's can also have flaws, but I see them much less than I see them in AMOLED panels - which is just inherent to the two different types of technology and how well the OEMs implement them. I was able to exchange the one in the photos of this thread for a new one (two guys at the store agreed it was an issue) and while the new one isn't perfect, it's MUCH better to where it's not all I see now.

There is truth in this statement. Despite my overall preference for LCD, when I use AMOLED for a period of time and go back, it's a two-fold reaction... one reaction is slight relief on my eyes, but the other reaction is getting used to the "dullness" - though I find I get used to that much faster than I get used to the high contrast when going from LCD to AMOLED. I would imagine if I stuck to a phone for more than a few months and that phone was AMOLED, the change back to LCD would be even more difficult.

Disappointed this is still an issue with AMOLED screens, this frustrated me to no end on my Galaxy S2 where the screen would shift yellow from one end to the other. Glad you posted this thread as it's not a widely addressed issue, guess I'm going with HTC 10.

I've never noticed this on any of my AMOLED displays. Nor have I noticed any burn in, and I'm not sure what you mean by "other inconsistencies," but if you mean sample to sample variation that affects LCD panels, too. And if you don't like the high contrast, that's adjustable in Display settings.
What I have noticed is vibrant color and ease of using in daylight that no LCD panel can match. Or even come close to. I guess I'm done with LCDs.
