Samsung Bets Big on Slim With Galaxy S25 Edge, Its Thinnest Smartphone Yet

A new design era unfolds with the Galaxy S25 Edge, blending sleek minimalism, premium titanium, and user-first innovation

It’s not just a thinner phone. It’s a design declaration.

Samsung has officially lifted the curtain on the Galaxy S25 Edge, calling it the slimmest smartphone in the Galaxy S series to date. But the sleekness? That’s only part of the story. This device, sharp in silhouette and subtle in design, marks a notable shift in how Samsung thinks about form, material, and the feel of its flagships. And no, it’s not trying to be flashy — it’s trying to be essential.

The company brought out two of its key design leads — Jiyoung Lee and Hyoungshin Park — to walk through how the S25 Edge came to be. The short answer? Balance. The long one? Keep reading.

Subtracting Everything That Didn’t Need to Be There

Lee, Vice President of Product Design at Samsung’s Mobile eXperience (MX) Business, puts it plainly: the S25 Edge is about “removing all unnecessary elements.”

That sounds simple, almost too simple. But it’s far from easy.

You’d think thinner phones would come at the cost of comfort or durability. But the S25 Edge holds firm, thanks to a smart mix of premium titanium, a one-mass design, and tighter bezels. Basically, this phone’s body is doing more with less — and doing it elegantly.

One line from Lee stuck: “We weren’t just trying to make it thinner. We asked, why thinner?” That’s not design fluff. That’s restraint — a word that rarely finds its way into smartphone launches anymore.

Built Like a Feather, Feels Like Steel

Now let’s talk about what it feels like in the hand. Because in the age of massive camera bumps and brick-sized flagships, feel matters again.

The S25 Edge weighs in less than expected. A lot less. The titanium side frame, lifted from the Galaxy S25 Ultra’s design DNA, gives the phone a polished edge without adding weight. Yet somehow, it feels solid — like it won’t snap if you sneeze near it.

Park, who oversaw the CMF (Color, Material, Finish) design, emphasized the interplay between subtle colorwork and that razor-slim form.

Three shades are up for grabs:

• Titanium Silver

• Titanium Icyblue

• Titanium Jetblack

They aren’t loud. They shimmer just enough. Think quiet confidence rather than in-your-face flash.

The Thinnest in Series History, But Not at the Cost of Character

Here’s something you might not expect: the S25 Edge doesn’t lose its “Galaxy” identity just because it’s thinner. If anything, it doubles down on it.

The one-mass design (fancy speak for integrating the frame and back seamlessly) gives it a fluid, cohesive look. And with bezels almost disappearing into the background, all that’s left is a smooth piece of tech that feels more sculpture than smartphone.

In fact, here’s how it stacks up against its siblings:

The S25 Edge is more than 1.4 mm thinner than last year’s already slim S24+ — a big jump when you’re dealing with millimeters.

Not Just Thin — Intentional

“Thin” is not the story here. Or at least, it’s not the whole story.

Lee said something that cuts through all the marketing gloss: “We weren’t designing to impress at first glance. We were designing for how it feels after 30 days.” That’s rare honesty in an industry addicted to wow-factor launches.

The design team didn’t just make the device thin for headlines. They made it thin because — when done right — it makes phones easier to grip, easier to pocket, and honestly, less annoying to use every day.

There’s intention here. A kind of quiet focus. Less spectacle, more satisfaction.

User Feedback, CMF Experiments, and a Lot of Patience

The design team didn’t work in isolation. Park says they looped in user feedback early, especially when it came to how the material felt, how light bounced off it, and what colors made the phone feel “premium” without being cold.

Here’s what shaped their choices:

• Users preferred deep but soft shades over flashy neons.

• Material tests favored titanium over aluminum for durability without weight.

• Manufacturing processes were optimized to create seamless joins between frame and glass without noticeable ridges.

The result is a phone that feels like it was made from a single piece of metal. No creaks. No weak spots. Just smoothness, front to back.

A Design That Leads, But Doesn’t Yell

Samsung didn’t shout about this launch. That’s telling. There was no Vegas stage, no glitzy livestream. Just a newsroom drop and a conversation with two people who clearly obsessed over every millimeter.

It speaks volumes about where the brand sees itself. Less flash, more focus.

The S25 Edge isn’t trying to out-shock its rivals. It’s trying to outlast them — in your palm, in your pocket, and maybe even in your memory.
