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."
incremental improvements and an overall nice phone, sure, but the ad I saw said it was gonna be the biggest revolution since the color TV.
What I don't understand is the IR port.
Don't like what's on TV in the bar? Change it!
You're making an assumption which may not be valid. First of all, the primary driver of screen battery life is brightness, not resolution. Second, if you're not doing something graphics intensive on your phone, the battery will get you through the day anyway. So your concern is mostly applicable when doing things like playing games and watching movies. Now, if you're watching a 1080p movie on a smaller resolution screen, the phone's graphics processor has to downconvert the image. So the question becomes, which is more of a drain on battery life - downconverting a 1080p movie to a 960px screen, or playing a 1080p movie on a full HD screen? This I don't know the answer to, but I suspect that it's a close call.

You're going to love that you can pop in a brand-new battery. The more the phone does, the more it will use up the power, the more recharge cycles, and the faster your battery wears out (note that battery running times become unacceptable long before the battery is actually gone).
Are you serious? A chief of marketing named Schiller?
People used to ask why desktops would need multiple processors. Most software now takes advantage of multithreading capability, and trying to use a single core process is downright painful.
It may not need to multitask many phone calls at once, but it most certainly may need to multitask a whole bunch of apps at once, especially on a phone that can do things like instantly translate written or spoken text, record and composite two video sources at once and audio in real time, receive notifications such as texts, keep track of calendars, locations, temperatures (?), heart rates (!), etc. while you go about whatever it is you're doing, running a pretty sophisticated operating system with a pretty sophisticated user interface, and oh yeah, take and process telephone calls. And don't forget that it might have to do some of these tasks twice, given that the phone can be configured to be running an entirely separate virtual OS for your work stuff.
Never ask why any electronics device would need more resources, whether it's CPU cores, memory, storage capacity, network bandwidth, or anything else. It's a sure recipe for looking back in five years and say, "Wow, I sure was dumb back then. I never dreamed that devices today would be able to [insert amazing capability due directly to advancement in hardware specifications]!"
The S IV's screen isn't LCD, it is AMOLED.
"We mustn't be caught by surprise by our own advancing technology" -- Aldous Huxley
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.
The problem with the S3 Mini is that it had almost nothing to do with the S3. It was a redressed version of one of Samsung's midrange smartphones. Even the Galaxy S2 was more powerful/capable in most situations, never mind the S3.
If that is your problem at least with Samsung you have the mini models.
The problem is that the mini models aren't just smaller screens, they're lower-spec generally. I suspect that most people that don't like the current bloat-o-phone/phablet trend actually want a nice fast processor, high-resolution display, lots of memory, a good camera, etc, they just don't want the ridiculously oversized phones. I know I certainly don't.
It isn't just Samsung, this sort of simple-minded "bigger = better, smaller = old phone for kids" mindset seems very common amongst all the smartphone manufacturers. [Samsung perhaps deserves a bit more of the blame, though, as they're an industry leader, so other makers probably tend to follow what they're doing to some extent.]
We live, as we dream -- alone....
Actually I find 5 inches to be about perfect. It'll fit my pocket okay and I can actually hold it.
That's what she said.
"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.
I've an S3 too, and we can't even accuse Samsung of wanting you to upgrade on every launch; you just buy whatever is fresh at the time you need it, so it'll last you as long as possible. I expect the S6 to be out by the time our S3's are severely obsolete.

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.
I'm running 2.3.7 and I just hit the WiFi button on one of the widgets.
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.
You can never know everything, and part of what you do know will always be wrong. Perhaps even the most important part.
Seen the profits Apple is making from phones? Apple won the game a long time ago.
You do realize that you're boasting about how hard Apple fleeced you, don't you?
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".
I'd ask for substantiation, but this quote is too subjective to warrant it.
- First they ignore you, then they laugh at you, then ???, then profit.
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.
I love my galaxy note. See I have a giant head so when I'm talking on the phone with my note it really helps make my head look smaller.
Paying taxes to buy civilization is like paying a hooker to buy love.
Funny, the reason I gave up on iOS was the limited app selection: no keyboards, no launchers, restricted VPN, no widgets, no third party tethering, no file system apps, limited ssh and web servers, limited third party music and video stores, etc.
The sales will depend more on marketing as usual, but..
1) That display is awesome, AMOLEDs are getting better and we're finally beyond retina density for AMOLED displays (the S3 had a pentile display which lowers the effective dpi a bit)
2) The 5" screen is not what decides the dimensions. This is actually narrower than the S3. It's a milimeter wider than my Nexus 4, which I could live with. When I bought the Nexus 4 I was wary of a 4.7" screen but it's surprisingly usable and I don't have large hands. I wouldn't want to go back to a smaller display for anything. Narrower bezels are a long needed advance, and Apple hasn't caught up yet - the Motorola Razr M for example squeezes a 4.3" screen in an iPhone 5 sized device.
3) It is slimmer and fits a far higher capacity battery than the S3. The effect on power consumption from the screen and new processor/GPU isn't known yet, but I bet this will do better than the HTC One.
4) Forget the lame launch, there are some genuinely cool features in there.
5) Not launching a 4.3 inch S4 Mini with top of the line specs is a huge and stupid omission from Samsung.
