Display
As the smartphone market continues to mature, the distinguishing between smartphones becomes harder and harder as OEMs continue to converge in platform and in most other aspects. This is most evident when looking at the progression from the Galaxy S2 generation to today. Back then, the Galaxy S2 was notable because of its Exynos 4210 SoC, which was far ahead of Qualcomm’s dual core Scorpion solutions at the time, which meant non-Samsung OEMs had notably worse CPU and GPU performance. The same was also true for the original Galaxy S with its Hummingbird SoC. Today, just about every OEM ships the same SoC. The difference between 8974AB and 8974AC is effectively only an eight percent CPU bump for the AC variant.
One of the key differentiators now in the market is display. The Galaxy S 5 features a 5.1-inch 1080p Full HD Super AMOLED display, equipped with the usual set of software defined color profiles. The GS5 gets a new adaptive profile that automatically adjusts the tint of the display according to the color of the ambient light. It's a neat effect, however Samsung's Cinema mode still ends up being the most accurate.
As always, we measure color accuracy using Spectracal’s CalMAN 5 software and a custom workflow for smartphones and tablets.
The results show that the Galaxy S5 has a display that is dramatically improved from the Galaxy S4. However, the Galaxy S line doesn’t exist in a vacuum, so it’s important to also look at how it compares against the best LCDs in other phones. In this department, things aren’t quite as perfect. To start, the color gamut control is still rather poor even on Cinema mode, as effectively all of the secondary colors miss the sRGB targets for saturation sweep. Yellow, cyan secondaries and green primaries are also notably out of the sRGB gamut triangle. While recent headlines have raved about the Galaxy S5’s record-setting color accuracy, I don’t see this at all in the results. Still, against the competition in the Android space, Samsung has improved a tremendous amount while other OEMs seem to be stagnating or even regressing in color accuracy. The only Android OEM that actually beats Samsung in the color accuracy department is now Google, which is strange because they contract out their hardware to other Android OEMs.
Looking at the saturation sweep, it’s evident that Samsung is now about equivalent to LG in color accuracy for their displays. HTC is barely ahead, with such a small difference that it’s not worth counting. Only Google and Apple have a noticeable lead in this department, a huge improvement from 2013 when Samsung trailed far behind most other competitors in this test.
In the Gretag Macbeth Colorchecker, Samsung continues to hold its position, beating all but Google and Apple. HTC is noticeably behind in this department compared to Samsung, as the One (M8) is horrific in this department compared to even the original HTC One.
In the contrast department, Samsung continues to dominate, with effectively infinite contrast. Based upon some quick viewing of the display in the darkest room I have in the house, I don’t see any obvious DC bias issues. Unfortunately, I still see some ghosting on the display at low brightness which manifests as a purple trail when scrolling. This seems to be unchanged from the Galaxy S4. The minimum white brightness is around 1.8 nits, which is great for reading at night, as many LCD-screened phones such as the LG G Pro 2 have a minimum white brightness of around 7-12 nits.
Samsung has also made great gains in the maximum brightness department, which is especially pleasing because for the longest time, AMOLED was noticeably less bright which made it incredibly difficult to read webpages and similar content outdoors. I’m happy to say that this is no longer the case, as the Galaxy S5 now has a display that realistically reaches around 440 nits outdoors with a pure white image, although this requires auto-brightness to be on and will vary with the screen mode. The maximum that is accessible without this daytime boost mode is somewhere around 350 nits.
The problem is the way Samsung has achieved this, something that is shown in the grayscale tests. While Samsung has done a great job in clamping down the white point to around 6504k, grayscale is so noticeably green that not only does CalMAN show this in the measurements, but also casual observation. I can literally see that the grayscale image is not gray, but an off-green. I’m not quite sure how this happened, but I suspect that this was done in an effort to increase peak brightness as even in the bluest display mode, green is still closely tracking with blue.
Overall, I’m quite pleased with the display. The AMOLED display in the Galaxy S5 is finally equivalent to LCD displays in color accuracy and peak luminance, areas that LCD used to be the best in. Throw in the incredible contrast that AMOLED has always had and the ability to toggle between wide color gamut and accurate color, and I would say that AMOLED is finally equal, if not slightly better than LCD. With a few more iterations, I wouldn’t be surprised if I were to write that AMOLED is clearly superior to LCD. Of course, there are some issues such as a noticeable green tint to the display in grayscale and Samsung still needs to improve their clamping of gamut to sRGB for Cinema/Movie mode, but none of these issues seriously detract from the viewing experience.

* 30 grams less than the M8. Substantially shorter too.az06093 - Wednesday, April 9, 2014 - link
Where's the video analysis?xmen77 - Wednesday, April 9, 2014 - link
S5 bestDisplay
S5 improved super amoled
z2 ips on the color RGB lighting with the addition of red and green phosphorus in diodes
All new one ips on the white backlight
M8 have the same quality as in the display М7
Cool backlight Z2, expanding the color gamut and "improves the shades",
actually distorts the color because all the images are designed for
standard sRGB and an extension will only be in the negative. Although
the display is still better than the HTC M8.
Amoled gradually improved and now he has lost almost all the shortcomings, there was only slight, noticeable only during the rapid motion of the screen (in front of screen) "modulation" at low brightness at maximum (it is comfortable in all conditions) this "modulation" No, I do not know why samsung does so in LG G Flex is no such (there is also amoled)
In OLED (Amoled) white whiter IPS, faster response in comparison to LCD
(hundreds of times better than LCD), contrast and black level is perfect
(hundreds of times better than LCD), colors
do not mix with each other,, ideal viewing angles.
Oversaturated color removed using a cinema mode

S5 1/2.6 isocell phase autofocus 6 lenses
z2 1/2.3 bsi 5 lenses
one 1/3 bsi 4 lenses
At S5 even crude firmware (new sensor) better color, detail and less noise
The rest of at the final firmware is very bad, especially in HTC

Metal is bad for the connection know about it all in the industry, aluminum is not a premium material, it is used for beer cans. At s5 soft touch texture like nexus7 instead of glossy plastic s4

Troll post. You say plastic is used for beer cans - plastic is used for trash bags.Aluminium is preferred.
TheSailorMan - Sunday, April 13, 2014 - link
"Preferred" for what? For helmets?? For car bumpers??? .......Aluminum is is the WORST material for smartphones. In many ways.
And YES , same drink in plastic bottle cost more than , if it is in cans. Check it out.
Plastic is MORE expensive than ALUMINUM. Check out this , too

Samsung Fanboy alert. Metal is far superior to plastic for heat dissipation alone. Not to mention it's more durable. And on what world is plastic more expensive than Aluminum?doobydoo - Friday, April 11, 2014 - link
And the metal phones have no problem with connections, either.ESC2000 - Sunday, April 13, 2014 - link
You just keep telling yourself that. The iPhone has documented connectivity problems. See eghttp://m.digitaltrends.com/mobile/iphone-5-problem... That list further notes that the aluminum chassis is prone to scratches (an apple VP says it's normal and to be expected... Not on my $800 device... Figure out how to prevent it). That list also notes the extreme battery drain problem I experienced on my iPhone 5, which died overnight the first night I owned it (failing to wake me up in the process). Owning an iPhone was a very underwhelming experience for me. After six months I dumped it for a note 2 and then a nexus 5 and have been much more satisfied. And my phone doesn't look like it's been to war like, for example, my stepfather's which has many dents and scratches.

It seems silly to me that you don't have a Lumia 1020 and a DSLR in your photo bench marking.crbandiera - Wednesday, April 9, 2014 - link
Very solid r review. Thanks for the useful balanced review. The information and your style as writer is refreshing as I am often times caught forced to ignore reviews due there extreme bias. I feel better equipped to make a purchase and that my expectations of what ever device I choose will be more realistic. Thank you for doing your job well.
