New device to be unveiled in New York City

If you're a fan of Samsung's Galaxy smartphones, you will be glad to hear the latest rumor making the rounds. Sources are indicating that Samsung is set to announce its next high-end smartphone called the Galaxy S IV on March 14. The mid-March introduction date was unveiled started with a tweet from Eldar Murtazin.

Murtazin wrote, "Save the date for a big announcement - March 14 :) And keep silence ;) HTC will miss HTC One sales again :( Like it was in 2012."

The Verge backs up that tweet, stating that March 14 is "definitely" the day that Samsung will be unveiling its latest generation flagship smartphone.

Another interesting tidbit that comes from the sources claiming to be familiar with Samsung's plans is that the manufacturer will focus on features rather than raw specifications.

The sources said, "The leap in cool new features from [Galaxy S III] to the next flagship will be bigger." That would seemingly mean that the leap and features would be bigger between the S III and S IV that it was between the S II and the S III.

Color and text rendering are awful. Better calibration could help a great deal but it still wouldn't help much with the pentile pattern and rendering of fine text. It is a terrible screen for such an expensive phone. Apple and HTC have much much better displays.

And the Droid DNA, drool

I totally get why Google switched from Samsung to LG for the Nexus, they got a massive upgrade in display quality by doing so. Crossing fingers that Samsung ups their own display quality with the GS4.

That's an awful comparison, because the pictures are zoomed precisely to the point where the S3's subpixels show up as colored elements in the jpg but the other phones' subpixels get blurred together.

Anyway, this thread is about the S4. In all likelihood, it will use the Note II pixel pattern, not Pentile.

The international S3 and all Note IIs have the option of more accurate colors. CNET did a test with the latter, and the iPhone's only tangible advantage is brightness, which is useful in the sun. Meanwhile, AMOLED gets 20x the contrast.

Actually that's not accurate. I own both devices and the iPhone 5's screen is the most colour accurate on the market to the point where if you put the same picture on it next to the G3 the superiority of the Apple device is obvious, even in 'Natural' mode on the G3. Amoled displaying Blue and Green naturally just has a very weird tint to it, though this is worse at any angle to the screen. I also found the pixel structure on the S3 awful, and wonder why more people don't notice especially on such a big screen.

The number of reviews that don't mention either the colour tint, the visible sub-pixel structure from a standard operating distance, lack of brightness in manual or auto mode (especially in sunlight, where it is intolerable) or the lousy trailing (time to to go from white to black per pixel) on the G3 is crazy. If you look at the Note 2 the display is night and day better, although I still tip my hat to the IP5 for more accurate colour and a decent 'retina' quality screen.

If Samsung can improve the screen for the S4 and put something a bit more revolutionary into it, it will be interesting to see what happens to Samsung's sales. They make the screens themselves, so there is really no excuse! The S3 in my mind stagnated a bit in technical terms from the success of the S2, all the more in the US market which received a neutered version anyway...100% agree that the Nexus 4 is a much nicer device overall, and much more how you imagine Google would like to present Android to the world.

I said "CNET tested the latter", i.e. the Note 2, in natural/movie mode, not the S3. It's more indicative of the S4 display, not the S3, so throw out 90% of what you wrote because it's irrelevant for this topic.

All LCDs, including the iPhone5, have bluish tints on blacks, and their many-times-too-bright output for blacks (which gets worse off angle or after pressing the screen) is percentage-wise far more inaccurate than imperceptibly inaccurate colors. You don't see that in deltaE results because they measure absolute error, not relative, and almost always measure primaries alone.

I don't know what trailing you're talking about, as even google can't find anything. LCD has far worse response time.

Tipping your hat to the IP5 for ppi (I assume that's what you're refering to by 'retina') is nonsense when the resolution is lower. Put the Note 2's screen further away from your face so that its image is closer in size to the iPhone and you get more angular resolution, not less.

I suspect Apple does some color calibration based on samples of the screen hardware they use in their phones, but it's not per device. This is a redux of the Mac vs PC in the 1990s. Apple made an attempt to color calibrate their computers and displays. PC makers did not. That's why Macs captured such a large share of the professional graphics and artists community.

In the 2000s, color profiling and color calibration started to become affordable making this a moot issue. Colorimeters are now in the $100-$200 range. Even if your equipment comes pre-profiled, there's often significant improvement from doing your own custom color profile. So even Mac owners doing professional graphics work own a colorimeter.

Which brings us to phones. Color accuracy should not be an issue on phones. It's a problem which was solved over a decade ago on PCs. Android and iOS simply need to add support for color profiles, and the phone stores need to have a $150 colorimeter. If you're unhappy with the color accuracy of your phone, the store could then generate a new profile, load it, and your phone's colors are now accurate. If the color of the screen shifts with age (as I suspect AMOLED does), then you just take it back to the store for a new profile every 6-12 months.

The only reason it's not being done is that the vast majority of phone buyers simply don't care. The only people who care are a handful of graphics professionals, and legions of fanboys looking for anything to argue about.

The thing is that they are pretty consistent between devices without user calibration, close enough at least. I've seen several myself and Anandtech's analysis corroborates it.

SRGB gamut and gamma charts are below: http://www.anandtech.com/show/6330/the-iphone-5-re...

The iPad 3/4 in particular is nearly reference quality out of the factory, something that is remarkable for a $500 consumer product. We've started using them at work for quick color passes on images when we're in the field. Very convenient and completely unexpected.

Getting this level of color calibration from other manufacturers would be great but HTC seems to be the only other company interested in making their screens look good.

Takin using some bs argument against an Android product? Noooooo

The pentile array is such that there are fewer subpixels per pixel, resulting in poor rendering of fine details and text. Color gamut and gamma are among the worst in its class. All of this is clear from normal viewing distance, magnification shows why.

Sharing subpixels rather than having three dedicated subpixels per pixel is not a good solution.

And even then their color accuracy isn't anywhere close to Apple's or HTC's. I'll take Anandtech's detailed color and gamma analysis over CNET's any day.

Incorrect, they're all at similar magnification levels. Note how close the size of the subpixels are to devices with similar PPI like the Nexus 4 and HTC One X.

The reason you notice the pixel array with the GS3 is the same reason text and fine detail looks bad on a pentile screen: pixels share subpixels with each other. The "higher resolution" GS3 has fewer subpixels than the iPhone 4S or other devices like the HTC One X with similar PPI.

The GS3's inferior rendering of fine details and awful color profiles are clear as a bell to the eye. You don't need a macro lens to make the point but it certainly makes it obvious.

Here's another one with the GN2: http://img.gawkerassets.com/img/185bfx75mrx0cjpg/x...

Also not very good. Why isn't HTC more popular among Android users? They clearly use better displays than Samsung, some of the best out there.

And to be clear, good: http://images.anandtech.com/reviews/gadgets/apple/...

Also good: http://images.anandtech.com/reviews/gadgets/apple/...

Not so good: http://images.anandtech.com/reviews/gadgets/apple/...

Like I said before, it wouldn't surprise me if display was one of the reasons why Google dropped Samsung for LG when it was time to make the Nexus 4.
