To PenTile or not to Pentile? That's the resolution - General Topics

I am sick of reading biased news and comments about the Pentile screens,
some say "don't care" and some say "it's crap", with or without evidence.
This "oppinions" war has become more evident after the internets learned about the Nexus's "sinful" PenTile screen
I just found this very interesting and objective article and wanted to share it with all of you:

Exactly. It's pretty much placebo. The only difference I've seen over time is in lighting. Used to be you only saw a perfect pic when looking at the screen from exactly one point, any tiny deviation would be hugely noticeable. Now that that's gone, it's all the same. Unless the resolution is really low, like 480x320, then you notice the grid. Beyond that, like I said, it's all the same.

Definitely not placebo. I had issues before knowing exactly what was different with the screen. I tried but could not get over the sense that the screen was crawling even with no interaction. Very disconcerting and after a few minutes use, definite eye fatigue. I could not do my usual news/blog reading on the train every day.
I know folks that have no issues with pentile so it's definitely not a universally bad thing. But it's a troubling trend to me because it significantly limits my options.

i've had a Samsung S8500 with Super Amoled PenTile screen (800x480), 3.3" then i bought my Desire S with the same nominal resolution on a 3.7" screen non-PenTile...the difference is clear even if the dpi is lower on Desire S, nothing shattering but without PenTile images are sharper

Some people see it and some don't. I noticed the "screen door" effect immediately on the Photon. I've heard that if you turn down the brightness it will lessen the effect but makes it harder to see the screen in sunlight. Most just keep auto brightness on and deal with it.

It's fine, and now with 300+ DPI phones, you cant even tell it's using PenTile

That's because it's a macro shot of a screen made up of 50% green sub-pixels. It will look white to the naked eye.

Motorola uses RGBW PenTile instead of the AMOLED's RGBG. It's really not the PenTile matrix at fault there - it's their use of it in a way too-large screen, combined with aggressive power-saving that causes off-colors and pattern visibility.
It's actually a bit different to the issues some have with RGBG. RGBG is actually pretty close to RGB stripe, but it relies on the make-up of the human eye. A relatively small number of people have a certain mutation that means their eyes don't exactly work the correct way for RGBG PenTile to be effective.
At the Galaxy Note and Galaxy Nexus' far higher pixel densities, the RGBG PenTile effect shouldn't even be visible to the naked eye any more. How it will affect those people who actually have a legitimate problem viewing it, we won't know until these screens actually reach the end-users.

To be honest I can't tell the difference with screens between my sgs 2 and captivate. Maybe my eyes aren't as good anymore because I regularly do art...

There is no noticeable difference between the two technologies that will be noticeable to the naked eye in normal circumstances. Period.

it really boils down to the user's perception of clarity of the screen.
but as long as it responds quickly that would be enough

You might as well want to elaborate to back yourself.
It’s actually next to impossible to see the dotiness or graininess of the on-screen image, on PenTile smartphones.

This is why i am excited to see LG's true HD 720p AH-IPS display found on the optimus LTE(s. Korea only). Reports and reviews are coming in that it is the best display on all mobile phone screen technology. Uses less power than super amoled and has crisper and sharper colors than the retina.

I haven't seen any review about that phone. However, I hope that these words don't come from LG Marketing team, which wrote in their product package manual that less gamut on Nova screen (67%) is better than SuperAMOLED's 107%.

No its not. If your eyesight is still in good condition you can notice the wierd effects like checkerboard, blue/red dots in fonts and jaggy edges. This is coming from using Galaxy S, but with Galaxy Note and Nexus Primes higher pixel densities I doubt theres going to be a big issue.

That depends an awful lot on exactly what you're looking at. With text, I have yet to try a pentile where the drawbacks weren't painfully obvious - and for me it does turn into pain in the form of eye strain and a headache if I keep at it.
With pictures it is sometimes obvious depending on subject. Moving pictures I rarely notice it but still develop eye strain after a while.
If you can't see it, you can't. Perhaps akin to color blindness. But to flat out claim it's next to impossible to see when it's actually impossible not to see for some is disingenuous. I'm not sure what kind of elaboration you want to convince you we're not just making stuff up as I can't easily show you what I see.
99% of my phone use is text. No games,rarely movies or pictures. Pentile displays I've tried all fail to be invisible for me so for now, they remove a lot of devices from consideration. I still try them just in case.

Does the og EVO have pentile idle if it does if it does and the EVO 3d doesn't I want to compare to see otherwise I would Like to look at a lcd non pentile vs a pentile not a lcd vs a amoled. I think that's a unfair judgement or if someone can tell me a phone that has a pentile amoled screen that's new I know the sgsii isn't I'm just curious to compare. This is like can one see the diff between 720p or 1080p. Some people say they look the same and iv had some say they don't see the hype in bluray which I find crazy. So before I throw my thoughts in is like to compare.

Samsung was so kind and sent me an Infuse 4G to help me developing for it. Thanks Samsung Mobile Korea
Infuse use a beautiful huge 4.5" Super AMOLED Plus screen.. But its driven with Galaxy S screen settings
DROID Charge is very similar to the Infuse 4G, except the display is a tad smaller. Super AMOLED Plus screen is also optimized for non "Plus" aka Pentile matrix.
That's why by default everything is over-sharpened and colors over-saturated.
I added preliminary support today for much more faithful screen settings in my one of my in-dev apps "Voodoo Screen Tuning", available for free on Android Market.
This app is very much experimental and not a final product. See it as an internal leak from a R&D lab. But as Linus tells: publish often, publish early
Please take a look at the app description, and have fun testing this app!
I need your feedback, so.. see you soon.
Installed, I see there are two options, native and samsung. I assume native is to return to stock and samsung are to switch to the optimized settings? I got superuser request and approved after hitting the samsung button. Didn't notice anything immediately so I rebooted to see if that would make a difference.
Don't know or can't tell if there is a difference.
Any way to tell? Good news is it didn't crash on the charge.
Native is screen without sharpening or color boosting.
Samsung is.. Samsung default.
I don't own a Charge for tests so.. only you can tell me
I installed and swapped between the two. I couldn't tell any difference.
I am on a voodoo kernel so I wonder if that makes a difference...

The Native setting is *much* sharper than the Samsung setting.
Very nice.
I don't see any immediate changes in the look of the screen, nothing changes (or it's so slight as to be unnoticable, and I do have pretty good vision) when looking at a high res picture with the overlay on and cycling back and forth.
But it is doing something, the button backlighting turns off and turns back on, but only when pressing the native button. Or maybe I'm seeing things from staring at my phone for the last 10 minutes like a jeweler setting a diamond or something.
Edit: It is sharper on native, very small text is more defined. Cool.

Same here. Not really sure which I prefer, native looks a lot sharper but samsung looks a lot smoother due to the blurring effect.
Sent from my SCH-I510 using Tapatalk
Samsung setting is over-sharpened, which means it should "look" sharper, but all it does for real is exhibiting a ton of artifacts.
I guess it's why you find "native" sharper, because it just display accurately pixels as they're supposed to be
− apply sharpening general UI elements and text really makes no sense to me, so it's not the case anymore.
Also: note that if your eyes are accustomed to an artificially sharpened image, the normal one looks blurry for a few seconds in comparison.
But that's just an optical illusion.
Does the setting stick across reboots, or does it have to be reset every time?
Prior to tweaking the settings, I changed my wallpaper to one I had on my Droid X, but was forced to change from because of how bad the colors looked on the Charge. It's took a few swaps back and forth, but I was quickly able to see the difference.
If anything, native appears oversharpened. I can even see a bit of a grid on my solid green background. Text under native, to me, is reminiscent of my old fascinate which obviously had a pentile matrix but that might just be the roboto font I'm using.
Edit: okay I take back that bit about it looking oversharpened. Just took a little getting used to when looking at text but DAMN there is quite a noticeable improvement in picture clarity. Thanks a lot.
Sent from my SCH-I510 using Tapatalk
Just put the screen in overlay and swapped between the options. The OP is correct, the difference hurts your eyes for just a few seconds, but once you go to "Native" you will never go back to "Samsung." The change is VERY noticeable on your home screen app icons.
Native:
Edges are sharper and lines are cleaner. Text appears slightly crisper and loses the perimeter fuzz that I thought was light bleeding before.
Samsung:
The text is a little "better on the eyes" but at the same time it isn't as clear as in the other mode. Lines and text have a very very slight bleed to them.
As a side note, No color changes are experienced. This goes along with the OP's previous comment. The change is simply making the pixels on the screen display more accurately not making the colors display differently.
That's my review. I also noticed that I wanted to keep my phone at a a higher brightness to really enjoy the screen experience.

Correct. I did not mean to indicate that the color gamut was changed, but my old wallpaper definitely looks better.

Native “looks" better on high Res photos.
Samsung makes text almost looked bold.
Proof: try the overlay option and open xda on your phone/Google and find a high Res picture, then just switch back and forth. You'll be able to tell the difference easily.

[Q] Super LCD 2 vs Super Amoled HD

I recently picked up a Galaxy Note for at&t and love the 5.3" Super amoled HD display. I've never been a big fan of Samsung phones and there cheap build quality but the Note's screen had me sold. On the other hand, I've always been a huge fan of HTC products and their premium build quality. I also prefer sense over touch wiz but that really doesn't matter seeing that I usually flash stock roms onto my devices. It really boils down to the display for me. So if anyone has seen the HTC One X in person or knows if the technology in the LCD 2 display is comparable or better than the Super Amoled HD display on the galaxy note, please let me know. I couldn't stand looking back at the grayish blacks on my old sensation compared to my galaxy note. I've read that the one x has great viewing angles but i haven't heard anyone compare it to amoled and i can't really judge from photos and videos as most displays look better in person. So... What do you guys think about the displays? Is it worth exchanging the note for a HTC One XL preorder? All help is appreciated and i will give thanks to those that are helpful.
Did you try hitting someone up on Twitter who is a tech blogger that made their way to Mobile World Congress?
Maybe someone will take the time to give you their feelings on the SLCD2 screen on the One X.
there are a couple people in the One X forums who are currently testing the phone. Since it is the exact same device sans chip and storage, I would venture there because there is a lot more activity. On a side note, I hear the super LCD 2 is a FANTASTIC screen...
Thanks. I'll try to do some more searching. I thanked you both. Also, I did find a beta tester but he has yet to mention anything about the screen. I'll shoot him a message.
Well I try the SuperLCD 2 in MWC and I was really excited because it's screen are very brilliant and colorfull. The black is strong black, not exactly how shows SuperAmoled but pretty well. I have a Sensation and has BIG difference betwen it.
And one more thing (not just an Apple ) the One X screen (same on One XL) is Super IPS screen.
I think that contrast is 1:10000 when in sensation was 1:7000.
Hope I help you! Sorry for my english xD

The amoled screen will probably have a better contrast and black-shades, if you use a black wallpaper Super AMOLED is probably also more battery friendly.
But I must say the screen of the One X impressed me in every video I saw, ofcourse that doesn't mean that much but it certainly means something.
The verge said the One X is the best display they've seen on a mobile device period. They said it will be the standard for all other displays to be held against now.
I wonder about any review that just says "it's the best display ever" without mentioning the specific categories it's the "best" in. Color accuracy? Brightness? Black levels? Off-axis viewing? Power consumption? Weight/thickness. Etc etc.
Most cell phone reviewers are guilty of this. TV reviewers are more thorough in this regard. If LCD 2 has black levels and power consumption similar to OLED I'll be impressed. I'm doubtful though. Black levels are huge for me. After owning the galaxy s2 and the galaxy 7.7 I'll never be able to go back to an inferior display.
SLCD 2 has better viewing angles, color accuracy, and white levels than amoled.
Amoled has better black levels.
Also this is full RGB stripe. NOT pentile. Making this the best phone display on the market currently.
yeah and what you seen on the screen seems to be over the glass.. the same effect nokia used with the lumia 800! (i've never seen a 900 so i don't know about that)..
That's just amazing.. I wish they used a smaller screen in order to have a better pixel density, but i guess that's enough
Android central posted a comparison of galaxy nexus and the one x. One x K.O the Pentile display of the nexus.
"The One X's display makes the Galaxy Nexus look like an old yellowed newspaper."
I cannot wait to compare it to the pentile samoled of the galaxy note and rgb samoled plus of the 7.7 for myself.

They mention all of that. Read the review. Colors are accurate, the panel is laminated. Viewing angles are impeccable. The resolution is incredible. You can see it outside in daylight. What do you want?
Anandtech will do actual measurements at some point, most people aren't interested in those.
That's the image comparison from Engadget(hope ok to post that)

After viewing the gorgeous non-PenTile 720p HD display on the One X for a few days, we realized just how difficult it was to revert to the S's qHD Super AMOLED panel. Let's put it this way: it's nearly the same screen as on the Droid RAZR, which comes as a tremendous disappointment to us. While we admit that the colors on the AMOLED display are a bit more saturated, that's all it has going for it. The pixelation is still easily noticeable -- in fact, it was the very first thing that stood out when we turned the S on for the first time. In contrast, the X's S-LCD 2 is definitely one of the nicest screens you can get right now, and there's no doubt it trumps the One S.
hi guys
Check out my youtube channel /staceyraver ....i did a video comparing the screens on the one x and galaxy nexus. There's also a couple of scratch test videos in there if you're interested.
alternatively all the posts are on my blog (with added photographs) at
www.techstace.blogspot.com
Super LCD 2 is apparently better!
When comparing both the screens with an image taken by a DSLR one X display seems to be more crisper and close to the original over more saturated amoled SIII screen, though the camera quality is said to be better in S3
Shreyas.
I have both the Nexus and the One X and the only advantage of the Nexus is the black levels. Imo super LCD has caught up in contrast levels and surpassed SA in viewing angles. The brightness output of SLCD2 kills the Amoled on the Nexus.
Sent from my HTC One X using Tapatalk 2
still amoled wins
I compared my One X screen to the galaxy S3 screen. Even though the colors of the HOX are more accurate and the screen is more bright doesn't change the fact that black just isn't black...
Also the S3 screen uses way less power and thus doesn't heat up the phone as bad.
For me the S3 is the winner, can't wait to switch from my HOX to S3 for this reason...

Only the iPhone has Retina Display
The Retina display on iPhone ushered in the era of super-high-resolution displays. Its pixel density is so high, your eye can’t distinguish individual pixels. The images and words are amazingly vivid and crisp. Everything just looks so real. In fact, once you see a Retina display, you’re never satisfied with anything less. Yet it remains a feature found only on iPhone and other Apple products.

Whats the definition of retina display?
300+ dpi & ips display??
There's no such "thing" as a retina display. It's a calculation based on what the human eye can process. This is from another thread but explains it.
On a small format device 1080P is a gimmick. Someone said they could tell the difference between HTC's 1080P displays and previous 720P displays. They couldn't; not unless they held the device closer than 10" or have better than 20/20 vision. And it has nothing to do with the display and everything to do with what the human eye is capable of processing. Does anyone know why Apple coined the term "Retina" display? It isn't about a specific PPI, it's about providing the maximum number of pixels the human eye's capable of resolving at 10-12" away which is the typical distance people view their phones from. For the iPhone 5 that's 326 PPI (it varies based on display size).*
Here's a little physiology lesson. The 20/20 human eye has a maximum visual acuity of 1 arcminute. That is, two points must subtend an angle greater than 1 arcminute in order for a 20/20 eye to resolve the two points. What this means for displays is that pixels must have an angular subtense of 1 arcminute in order for your eye to resolve the detail in the content. Above that, your eye could discern things like jaggies on text and the edges of icons. Detail below 1 arcminute isn't perceived by the human eye any differently whether a display has 267 PPI or 468 PPI. The Note II’s 5.5” display at 267 PPI has an arcminute subtense of 1.073 which, based on the size of its display, is near perfect. The One’s 4.7” display has an acrminute subtense of 0.64 and anything below "1" is wasted.
And with the new fixation on resolution things like brightness, contrast, and color accuracy get swept under the rug because all people are focusing on is a PPI count rather than the actual quality of the display. To get to 1080P every display released so far has suffered in quality in some way. The DNA's display was less bright with less contrast than the One X's and the One's has less color accuracy with poor color temperature.
So, with the human eye being the lowest common denominator the selection of PPI is being done ass backwards. Deciding on the optimum PPI for any given device should be an arithmetic equation; not manufacturers arbitrarily pulling numbers our of their butts to out-feature each other. The above talking about what the human eye can process is irrefutable fact (ask your ophthalmologist). With an arcminute subtense of "1" ideal for the human eye to process detail, the manufacturers should pick the*lowest*PPI that achieves "1" arcminute at 10-12" away. Why the lowest? Because the higher the PPI the bigger the drain on the battery, GPU, and CPU. And why reduce the performance of a device when the end result is the human eye can't process the additional detail being provided anyway?
It's all kind of moot anyway because as OP pointed out, it's a "gimmick" to sell more phones. So we're all going to end up with 1080P displays one way or the other because that's where manufacturer's marketing is taking us.
Also, the additional detail higher PPI displays are capable of only apply to CGI like the UI, buttons, and text. Pictures and video are spread out over more than one pixel and are never aligned with the pixel structure of the display so their inherently fuzzy. Videos are even worse because their also moving.
This article explains further on how PPI impacts content on a small format device.

I view my Note 2 only 6 inches away from my face. I can't even imagine viewing that TINY iPhone 10-12 inches away from your face.
Ya, the thing is that nobody else calls it a "Retina display"...even though about 10+ phones have a high PPI than the iPhone 5. It's just the name. Hopefully with the next model they can make a phone that actually stands up to modern phones spec wise.... (yeah right.)
I've been an Android user for a few years but work recently provided me with an iPhone, I have to say the new Android phones coming out has me tempted to purchase my own phone and walk around with two phones.

Yeow! I love this!
Oh look, another typical android circlejerking thread that has absolutely nothing to do with the phone of the section.
Apple invented the Retina name right after they invented the rectangle with round corners.
The retina screen is made by Samsung (if I'm not mistaken) apple didn't create anything, a bunch of pencil pushers behind a desk designed it overnight....

Washed out viewing angle

Can all of you people with "perfect" displays and viewing angles post picture of your device at an angle if you were look at it from a table and other angles.
I DON'T CARE IF YOU LOOK AT IT FROM THE FRONT and say "oh well I look it from the front all the time." I view my device on the table 1/4 time. So this is an issue. Don't get me wrong I love this device.
MINE IS BAD. I know there are threads similar like this but you people NEVER back up your claim of it being perfect and saying "I don't have that issue."

WELL PLEASE POST PICTURES OF A LOT OF ANGLES! PLEASE AS PROOF!
I'm trying to investigate this issue because I'm reading the display on this device is the BEST DISPLAY EVER. I don't believe this is true at all. MKBHD has this issue too. I add this device for a week and I know I have only 15 days before it's too late to get a new one and not a "refurbished" one.

If you perceive it as an issue you might want to go with the next badass $350 off contract device available... This is something that is mentioned in almost EVERY review video I've seen, but I don't read my screen from an angle and don't see it as an "issue".
good day.

I've only seen two videos point this out and I hoped it would be a defect. All the others out said this display is "perfect" and so on etc.
I want to see the pictures from the people who claim the "perfect" display and says "I dont have that when I look at mine from an angle."
Cuz I've seen plenty who claims that in just one thread involving this issue. Yeah it's a low priced device, but we all know Google doesn't really make money off this device at all, it's the services your using and the ads you see when your using it that pays them back.
I just want to see the pictures of those who claims their device is perfect.
Sent from my Nexus 5 using Tapatalk
Reviewers may test extreme viewing angles for comparison but generally evaluate the quality when viewing the display head-on in the manner most people view the device while it's held in normal use. Mind's perfect, but I could not very well use it if held at a 90° angle.
My viewing angles are nothing like that. I have no trouble seeing my screen from those angles.I know you are looking for pictures but unfortunately m n5 is my only camera right now. If i can get some pics I'll post them.
Mine ain't perfect but they seem much better than yours. At least with my eyes, maybe your camera make the things worst ?
I don't have any camera either, but seriously I can see the tiles much better than you, even with extreme angles.

Galaxy Nexus. Yah i know blah blah blah blah saturated. I deal with a HTC ONE too. I actually ENJOY the display on the ONE more then my Galaxy Nexus. THAT display is GORGEOUS! I wish I could just tear it off and use the ONE's display instead lol. Or at least get the viewing angle it gets.

Heh, I wanna say galaxy nexus. Which I also came from as well. Galaxy nexus amoled panel blows chunks next to the n5.
On topic: Since you forced me to sorta care, I got to lookin at the angles. When I got directly up/down/left/right it performs as well as an ips display should with solid color at extreme angles. But on the diagonals of the extremes i.e. (Right/down) I noticed that's when the back light washout would be visible. I suspect it has something to do with any type of polarization that has been applied to the glass.
good day.

agreed.
Have you ever noticed how every review tests viewing angles from a straight angle? That's the standard and probably for good reason.
Sent from my Nexus 5 using Tapatalk
Mine wishes out when I look at it diagonally and off-axis. There's only minimal washing out from the top, bottom, and sides, unlike what you're seeing. I'll try to track down a another camera and take a couple photos to show you.
EDIT: Here you go. As you can see, there's some washing out at extreme angles (mostly from the diagonal), but it's nowhere near as bad as you're experiencing.

Which is why it's bad for viewing on tables like I said. Because your viewing it from diagonal perspective a bit. Left and right and up and down are Barrable. It's not TOOO bad. Of the diagonals were the same I'd be OK with this.
I wanna know if this is a Screen lottery (every device has this but some worst then others), which is why I requested pictures from the "perfect" people. If I see that they are having even a significantly better display compared to mine(I know IPS displays get washed out at angles but mine is HORRIBLE), then I wanna call Google and get a new one and compare those too.
I've yet to be able to compare my Nexus 5 to another. Probably tomorrow I'll go into a T-Mobile or Sprint retailer and compare (hopefully it isn't bright in the room because it's harder to tell the difference).

Maxpower7 thanks! I appreciate those pictures. Is that maxed out brightness on a stock kernel with stock colors? That's what I'm using ATM(For personal reasons hopefully I can announce it when it's done.)

Stock kernel, no color adjustments. I've never used max brightness on any device. I'm at roughly 1/3 brightness and it's still plenty bright for me. I can try another one at max brightness if you want, but I don't keep it that high personally because it's too bright for my eyes and it also kills the battery.
EDIT: here's max brightness.
No Maxy it's fine thanks. I just wanted to know for sure.

Yeah they're bad. So was the nexus 4 and g2. It's the type of polarizer that LG uses.

Someone at LG needs to be FIRRRRRRRRRRRRRRRREEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEDA.
Can this "issue" be fixed? Can the angles be improved? I remember reading the Nexus⁴ got some AOSPA Love and it got "fixed" not sure if it was color wise or angle wise or both since I don't own one.
Sent from my Nexus 5 using Tapatalk
Mine gets quite washed out an angle, but I can still read everything on the screen just fine so it really doesn't bother me. It's a little annoying and unfortunate just to know it's like this (especially since my N7 2013's IPS screen is absolutely perfect even at the most extreme angles), but it really has no effect on my usage of the device.
Seems extreme to wish for someone to lose their job over this. If this is affecting you enough to feel that strongly about it, perhaps a different device would serve you better.

My point in posting those photos was to show that it's really not that bad at all, and it actually looks worse in the photos that it does in person. To suggest that someone should lose their livelihood over this non-issue is utterly ridiculous because this screen on this phone is pretty awesome. And I'm picky about displays.

Disadvantages of Galaxy S5 and request for future phones

Samsung please make in the future smartphones:
OIS
Remove modulation at medium and low brightness, as it did in the Fly IQ444 Diamond 2 Quattro, Motorola Razr HD (XT925) and LG G Flex

Remove Dynamic and Standard modes. These modes are as bone that samsung threw for some reviewers and haters. Benefit from them is no, only cons. Because at testers gray is blue, red is orange, they specially put this modes, they have very cold tone (6500-6700K - Cinema and pro photo mode, 7500-8000K - Dynamic and Standard). Anyway all image are designed for SRGB standard, and enhanced range is color distortion, red hues (at normal color temperature) and oversaturation.
Сomplete yet color gamut to 100% SRGB, the unnecessary 6-7% still sometimes make themselves known. (but 106% instead of 122% in S4 is a good job).
http://www.youtube.com/watch?feature=player_detailpage&v=7PP8mgv0eCY#t=798 (This is Cinema Mode)
Metal Body (antennas should be behind the plastic, glass or other material, but not metal, so did HTC, Apple and Sony, otherwise the connection will be very bad).
Thanks
It would be ideal. Isocell, improved super amoled (brightness, viewing angles, color reproduction in cinema and pro photo mode, anti-glare), waterproof, interface speed and battery life is awesome.
Who are close to the developers of samsung, please show them this post
I'd think there are many more important issues with phones nowadays than screen calibration. If you want to edit photos, get a good monitor and calibrate it. If you want to watch movies, get a 65" plasma or OLED and stop complaining about stuff that has little relevance in smartphones.

It is much more important than unnecessary megapixels, megahertz, cores and ppi's.
It's about quality of display, which can be much better,
about the impact on eyes and eye fatigue,
about shooting in low light,
about solid and feeling that you hold the thing for ages
about "vulnerabilities", which can fault reviewers and haters

I prefer a fast phone with a perfect screen, than a slow phone with a good screen.
We already have good screens and if Samsung devotes loads of hours to making the screen much better, they will either need to make the phone super expensive to pay for those extra hours or they will have to cut corners in other areas to save money.
The law of diminishing returns - you spend 10% of time to achieve 90% of what you want and 90% for the rest 10%.
Less screen modes? More accurate? It will be a cold day in hell when Samsung stops emphasizing the saturated colors that only come from AMOLED. There's a reason why they use it on all flagships.
Lots of people prefer that saturated profile.
I would be always against taking choice away from customer.
Cinema is quite good Btw. Not perfect but it's close to accurate.
First thing I did when I bought this phone was changing the screen mode. That's Android strength: let me choose.
OIS: yes please.
Metal body: only if it's not form over function.

The main advantages of amoled is not oversaturation and distortion. The main advantages is ideal black color, ideal contrast, ideal viewing angle, ideal response speed, all much better than lcd
That's true, S5 doesn't look like a 2014 flagship.
