Every generation of the Galaxy S series brings a fresh vocabulary with it. On one hand, that’s manufacturers differentiating themselves; on the other, it signals genuine innovation cycle over cycle. So let’s walk through the key new terms and unpack what makes the S8 special.

1. Infinity Display: Stretched Vision

“Infinity Display” captures the essence of a curved bezel-less design about as perfectly as words can.

A high screen-to-body ratio (i.e., glass dominating the front face) means more sophisticated engineering, and the visual payoff is top-tier: the field of view opens up, and the viewing experience is elevated to a new level. Last year’s Xiaomi Mi MIX — clearly a forward-looking experiment — was bound to set the design trend for 2017. ID (Industry Design) has always been the guarantor of a phone’s aesthetic appeal, but this kind of bold, avant-garde thinking comes with a weakness: holding what’s essentially a slab of glass means you’re constantly terrified of dropping it.

The Galaxy S8 uses Corning Gorilla Glass 5 on both the front and back, framed by polished aluminum alloy. The result is a body that feels like a single, seamless piece of glass. With an 84% screen-to-body ratio, your first impression upon picking it up is probably: the body isn’t even that big (the S8 is 5.8 inches), yet the screen looks absolutely stunning.

So what does the future of phone design look like? Near term, it’ll likely evolve into a smart, waterproof slab of glass (or some other material), and later into foldable or rollable flexible displays (Samsung, LG, OPPO, and Meizu all have patents on file). Eventually, the “phone” form factor may vanish altogether, replaced by wearables — or even implantable devices.

2. Bixby (Beta): A Smarter Phone Experience

Smart assistants on phones are nothing new. iPhone has Siri, Nokia had Cortana, Google has Google Now… You’ll notice that artificial intelligence has become the shiny object every tech giant is chasing. That makes total sense, and it’s easy to understand. Plenty of diehard Nokia fans once held up a Lumia next to an iPhone and declared Cortana smarter than Siri. But when you’re on a noisy street or in a quiet conference room, voice assistants fall flat — and traditional card-based reminders and habit-aware life alerts still have a real place.

Bixby is the S8’s smart assistant, blending a card-based interface with voice services. In fact, iOS 10 — released back in September 2016 — already supported Widgets, which are essentially card-based. You swipe left to bring them up. Samsung went further and gave Bixby a dedicated hardware button on the left side of the device.

You can think of this button like the ubiquitous Fn custom key on cameras.

Bixby lets you control a surprisingly granular range of functions — even snapping a photo of something you like and instantly searching for it online (a feature previously used on the Samsung Galaxy C9 Pro). More routine things like setting alarms, sending emails, or conversational interaction are naturally smooth too.

When you’re deep inside an app or several menus down, the physical shortcut really shines. On iPhone, Widgets require going back to the home screen and swiping left; Siri needs a long-press of the Home button to invoke.

Smart assistants are an inevitable stage in the humanization of phones, and they depend entirely on advances in cloud computing and artificial intelligence. Today, every major player has its own: Apple’s Siri, Microsoft’s Cortana, Amazon’s Alexa, Google’s Google Now, and now Samsung’s Bixby. Top-tier software can’t exist without hardware support — all the cloud computing and AI in the world is meaningless if the hardware can’t collaborate to weave it into our daily habits. This battlefield is still in beta. Let’s see how it plays out.

3. Iris Recognition and Facial Recognition: Security Goes Vertical

The fingerprint sensor sits on the back, symmetrically aligned with the flash. Until someone cracks “fingerprint recognition through a flat sheet of display glass,” this is clearly a technical compromise. At first glance, many will worry about accidentally smudging the camera lens — but Samsung cleverly ringed the sensor with a strip of metal, and your finger will build tactile muscle memory after just a few uses.

If fingerprint unlocking isn’t flashy enough for you, there’s iris recognition and facial recognition. Every person’s iris is unique; every face has distinct contours. The real pain points for this kind of intelligent biometrics are response speed and security — whether for unlocking your phone or, eventually, for online payments. Once the Galaxy S8 lands in China, you can bet that domestic internet service providers will scramble to build real-world use cases around these features.

Both iris scanning and face unlock are built on algorithms: iris image quality assessment, iris region localization, preprocessing, feature extraction, template generation, and matching. The upshot is: as long as the algorithms are solid, every manufacturer can do it. It’s just a matter of time.

4. The Photography Experience: A Beefed-Up Front Camera

Everything I’ve written so far has been about craftsmanship, experience, and interaction. We haven’t even touched on photography yet. The Galaxy S8 upgrades the front camera from the S7/S7 Edge’s 5MP to 8MP, and adds autofocus. This, of course, is also the foundation for iris and facial recognition.

While the S8 still packs a 12MP rear camera, Samsung claims it offers faster image signal processing (ISP) and better low-light performance.

Broadly speaking, S8 photos tend to be vivid, bright, and punchy, with excellent shadow detail; the iPhone 7’s output, by contrast, more faithfully reflects the actual tones of the subject.

Smartphone photography has always been a matter of taste. Some people love straight-out-of-camera results — in which case the Huawei P10 is the obvious pick: no editing needed, just shoot and share. Some prefer faithful documentation, and they’d lean toward the Google Pixel or the iPhone 7 Plus. And some people just dig the Samsung-style shooting experience — in which case, go try one and decide for yourself.

5. One Last — Slightly Out-There — Thought: How Do You Turn a Phone Into a Computer?

Yes, this is clickbait territory, but it’s also the most imagination-stoking question. When a phone’s RAM and processing power are plentiful enough, the device might be able to stretch from office productivity all the way to gaming.

This time, Samsung’s external accessory is a bowl-shaped dock — resembling a wireless charger — equipped with HDMI, USB, and Ethernet ports. Translation: grab a monitor and you can use the S8 as a workstation. The operating system isn’t Android; it’s Remix OS — which looks a lot like Windows.

Apple, just days ago, had a patent surface showing an iPhone slotting into a MacBook chassis. That kind of terminal interaction feels very direct, and could signal a new direction for Apple’s cross-device connectivity — shared files, shared operating systems, seamless app handoff between devices. But the precise implementation remains unclear.

I’m sure plenty of manufacturers dream of merging the computer and the phone — or at least making them a lot more intimate. Right now, Apple connects everything through iCloud, but hardware-level integration is definitely part of the roadmap.

I’ve rambled on quite a bit. What part caught your attention?

In any case — whether you like Samsung or not, whether you’re still holding the Note 7 battery fiasco against them — there’s no question that the Galaxy S8’s innovations are multifaceted, and the Galaxy line has been consistently pushing smartphone hardware forward, especially when it comes to the broader trend of industrial design aesthetics. Beyond that, Samsung has a complete supply chain that no other manufacturer (except Sony) can match. That built-in advantage alone will keep Samsung competitively relevant for a long time to come.
