Samsung Unveils the Galaxy S4

adeelarshad82 writes "It's been leaked, teased, accused of being a copy of its predecessor, and celebrated as the likely champion of the mobile ecosystem for 2013. Samsung has finally unveiled the next in their line of globally available smartphones, the Galaxy S4. The phone carries a 5-inch Super AMOLED display with 1080p resolution at 441ppi, weighs only 130 grams and is no more than 7.9mm thick. On the inside, the Exynos based Octo-Core processor clocked at 1.6 GHz and the Snapdragon based Quad-Core 1.9GHz processor power this machine. Galaxy S4 is also packing 2GB of RAM and a 2600mAh battery, and its microSD slot is accessible though the removable rear panel. The S4 will include several new features, such as Air Gesture, Smart Pause, and Smart Scroll. Samsung's vice president of portfolio planning said many of the software improvements in the Samsung Galaxy S4 could make their way into existing Samsung Galaxy S3 phones."

    Jelly Bean was released in November, making it 4 months old, 5 months by the time the SIV is generally available. Jelly Bean will be obsoleted by Key Lime Pie at Google's I/O developer conference in May so you get a whole month to enjoy being on the current version of Android, that might be some kind of record. After which you get to wait another 4-5 months for Samsung to get the OS up and approved by US carriers.

    "It" doesn't scale to 8 cores. It's a 4 core processor where each "core" has both a low power and high performance core that it selects between. Only 4 cores are operational at any given time.

    Of course, that doesn't matter to the tech-savvy membership of /. 8 is greater than 4, that's what counts.

    If you compare subpixel density, the SGS4 is 882 subpixels per inch, my lumia 920 is 1280x768 with a pixel density of 332, comprising three sub pixels and 4.5 inches, therefore the subpixel density is 996 per inch, therefore if it was pentile it would be 498 ppi.

    No, because your eyes suck at seeing blue. Your eyes have very poor resolution in blue, moderately better resolution in red, and sharpest resolution in green. The whole point of a pentile display is not to waste subpixels on blue and red that your eyes can't even see. So you put in more green subpixels than red or green.

    Put another way, even though the Lumina has 996 subpixels per inch, 67% of them are much higher resolution than your eyes can resolve, while 33% (green) are lower resolution than your eyes can resolve. So you're actually wasting a lot of subpixels. With a pentile RGBG display, the ratio of subpixels better matches your eye's resolving ability. 50% of the pixels are devoted to green, 25% for red, 25% for blue. So pentile can produce a sharper looking picture than RGB while using fewer subpixels. Pentile only looks bad if you unrealistically put your eye right up to the screen or take a magnified photo.

    And before anyone starts rebutting that they can see the difference, no you can't. This trick is not new nor did it start with Android pentile displays. It's been used in NTSC TV broadcasts, color film formulation, and JPEG and MPEG compression. All of those store and display red and blue at a lower resolution than green. That you never noticed this before is proof that it works. It's just new to computer displays because until recently we didn't have spare computing power to waste on converting RGB data for a single pixel into a RGBG subpixel array millions of times in real time.

    Not on Android. There was no way to turn on WiFi with a single click until Android 4.2.2, and even in Android 4.2.2 is it a press and hold, not a tap.

    With a five inch screen it's a small tablet! I wouldn't mind having one, but I'd still need a phone, my pocket isn't that big.

    In terms of size - the S4 is actually smaller and lighter than the S3 - even though the S3 only has a 4.8" screen.

    S3: 136.6 x 70.6 x 8.6 mm, 133 g
    S4: 136.6 x 69.8 x 7.9 mm, 130 g

    The screen runs closer to the edges, and the buttons at the bottom are slimmer. All in all, some pretty neat engineering.

    It's a 441ppi _PENTILE_ display.

    A proper display LCD has 3 subpixels per pixel, which means a 326ppi display actually has 978 dots per inch.

    A 441ppi pentile display has 2 subpixels per pixel, which is 882 dots per inch.

    So strictly speaking, the Galaxy S IV still has less pixels per inch than the last 3 revisions of the iPhone. In fact, I think even the Galaxy S II might have had a better display than this new one.

    This is ridiculous. How is the smartphone who most people (at least in US) own is a fashion accessory?

    1. A smartphone is a "which" or a "that", but not a "who". (At least you didn't use "whom" as a nominative, thank random factors for small favours.)

    2. Most people in the US wear shoes, which are highly functional and indeed in many circumstances necessary items, yet they too are often regarded as fashion accessories. Life is fraught with such mysteries!

    That's... not how it works. The "penta" part refers to a prototype arrangement that isn't actually in use in any phones (see here: http://en.wikipedia.org/wiki/PenTile).

    These phones are using the RGBG pattern, which has the greens 1-to-1 with the pixel map, which means each pixel is either a green-with-red or a green-with-blue. So the parent here did do the math correctly.

    Well, the last two quarters they were outselling all other smartphones on every U.S. carrier that carried them.

    Even if this were true, what an incredibly misleading statement. Android has 75% of the smartphone market outright, and rising FAST. I have no idea if Apple somehow outsells every other *individual* model of cellphone (or however else your statement might be twisted to be "true"), but the raw numbers most definitely support the rhetorical asking/observation "where's Apple in all this".

    And all those cores are of little use without software to use them. iOS still has a huge quality and power lead in apps.

    I'd ask for substantiation, but this quote is too subjective to warrant it.

    While Samsung doesn't lock down the bootloader they do a few underhanded things to ensure warranty claims can identify phones which have had their firmwares played with. Flashing custom firmware on a Samsung Galaxy phone causes a yellow triangle to appear during boot. This is a feature in the bootloader firmware. Fortunately the XDA guys have figured out ways around it, but the phone is definitely not open in the same way a Nexus is open.
