Samsung Galaxy S4: What to expect from the most anticipated smartphone of 2013

 

In an attempt to steal the thunder from Nokia, Asus, Sony, and a slew of other mobile device makers at Mobile World Congress 2013 in Barcelona, Samsung has announced that the Galaxy S4 will be unveiled at its own exclusive event in New York on March 14, with public availability to follow soon after.
With the slow but inexorable waning of the iPhone, both in terms of mind and market share, the Galaxy S4 is probably the most anticipated phone of 2013. The question on everyone’s lips, though, is whether Samsung can push the smartphone (and Android) envelope forward, despite lackluster innovation from Apple — and in the face of strong offerings from HTC. Let’s run through the expected hardware and software specs of the Samsung Galaxy S4, and then analyze the current state of play in the mobile space.

Hardware

The Samsung Galaxy S4 is expected to have a full-HD 1920×1080 display (up from 1280×720 on the S3) — and the display might even make the jump from 4.8 inches to an edge-to-edge 5 inches. There were some early rumors of a flexible display, but they can be discounted — the tech just isn’t there yet. It remains to be seen whether the underlying tech will be AMOLED or LCD, though reports suggest that Samsung’s AMOLED production line isn’t ready to produce 1920×1080 5-inch displays, while the LCD production line is raring to go. Maybe this will mean that the Galaxy S4 can finally compete with the iPhone in terms of image quality and accuracy.
Under the hood, the Galaxy S4 is expected to use Qualcomm’s quad-core Snapdragon 600 or 800 SoC. The Snapdragon 800 is particularly exciting because it’s the first chip to be built on TSMC’s new 28nm HPM (high performance mobile) process — though, at 2.3GHz, it might be more of a tablet part. There is also the possibility that we’ll see two Galaxy S4 SKUs — a Snapdragon model with integrated LTE for the US market, and an Exynos-powered model for the rest of the world. If the S4 does use Exynos, the most likely option is an eight-core Exynos 5 Octa — four Cortex-A15 and four Cortex-A7 in a big.LITTLE configuration. There are still big questions about whether the power-hungry Cortex-A15 is suitable for smartphone use, so it will be interesting to see how the Galaxy S4 pans out.
Rounding out the hardware, the Galaxy S4 is expected to have a high-res camera (13MP, according to some rumors), up to 64GB of flash storage, and 2GB of LPDDR3 RAM. Following the weak, uncertain, and confusing introduction of wireless charging in the Galaxy S3, we expect the S4 to rectify the situation and provide wireless charging by default. You can also expect all of the usual kitchen sink: WiFi (which should step up to MIMO), Bluetooth, GPS, NFC, and so on.

Software

There are unlikely to be any surprises in the software department: The Galaxy S4 will almost certainly run a TouchWizzified version of Android 4.2 Jelly Bean (sorry, Tizen fans — keep on dreaming). There is also a rumor that the Galaxy S4 will launch with a pad accessory, which, when bonded with S Health, will give your phone the ability to measure your pulse and blood sugar, among other things.

Evolution, not revolution

In short, all indicators point to the Galaxy S4 being a fairly gentle evolution of the Galaxy S3 — a lot like the iPhone 4 and 5. A 5-inch screen would be exciting, but it really isn’t that different from 4.8 inches. An octa-core Exynos would certainly offer a unique selling point — but when you remember that four of those cores are wimpy, and that the Cortex-A15 cores are the reason your smartphone only lasts for six hours, your excitement will be quickly tempered. A laser keyboard, like the one shown in the (fan-made) video below is unlikely.
