When Samsung dropped the Galaxy Z TriFold, one guy didn't wait for a launch in his home country. Yasuhiro Yamane, a Hong Kong-based IT journalist who's spent two decades reviewing smartphones and somehow amassed 1,800 of them, got on a plane to Korea the moment the device hit shelves. His reason? He was convinced this tri-folding form factor represented something genuinely different in mobile computing.
When you've owned 1,800 mobile phones over two decades, you develop an eye for what actually matters. Yasuhiro Yamane, a Hong Kong-based IT journalist who's covered smartphones since 2003, doesn't do hype. So when he heard Samsung was releasing the Galaxy Z TriFold - a genuinely novel multi-folding form factor - he didn't wait for reviews or retail availability. He booked a flight to Korea.
It's a telling signal about how Samsung has positioned foldables. Yamane tells Samsung Newsroom that he believes their foldable lineup stands out not just for the display technology, but for something more fundamental: "a foldable-optimized user interface" with genuinely useful split-screen functionality and multitasking. Most hardware makers bolt software onto form factors. Samsung built the software around the fold.
What struck Yamane most upon unboxing? The immediate sense that this wasn't just an incremental hardware refresh. "From the moment I first held Galaxy Z TriFold, I was struck by the sense that it was an entirely new kind of device - one that breaks the boundary between a smartphone and a tablet," he explained. The 10-inch unfolded display is genuinely expansive - roughly equivalent to three phones stacked together - yet the device somehow managed to feel "solid yet slim, lightweight and comfortable to hold" when unfolded. That's no accident. The engineering here bridges form factors in a way that hasn't existed before.
But specs on paper don't tell the full story. What matters is what you actually do with 253 millimeters of unfolded screen real estate. Yamane's been living with it since purchase, and the productivity gains are real. He's running three apps simultaneously - email in one window, navigation in another, PDFs in a third - and the display still feels "spacious and comfortable." That's the aha moment. A 10-inch tablet-mode screen doesn't just let you do more; it lets you do it all at once without feeling like you're working in a phone-sized viewport.
The UI design matters here too. Unlike devices that bolt tablet mode onto a phone interface, the Galaxy Z TriFold's dual-fold structure seems almost purpose-built for its form factor. Yamane describes the experience as "natural and intuitive," which isn't corporate fluff - it's the difference between a device that feels like someone thought it through versus one that feels compromised.
Practically, he's discovered the device reshapes work habits. Paired with a Bluetooth keyboard, he's writing articles while researching simultaneously. Split the screen vertically - video on top, social feeds or messaging on the bottom - and even in cramped subway cars, you're not overwhelming nearby passengers while getting more functionality than a traditional phone. Samsung DeX integration extends that productivity even further for actual desk work.
What's striking is Yamane's perspective through the lens of mobile history. This is someone whose first Samsung purchase was the SGH-E400 flip phone back in 2003. His favorite device remains the Serenata, the Bang & Olufsen co-designed music phone from 2007 - a device so refined "even the alarm sounded pleasant." That's not nostalgia talking. That's someone who understands craftsmanship. And he's saying the Galaxy Z TriFold hits differently.
The real market signal? Yamane returned to Japan and showed the device to about 100 people. Almost universally, they called it "a completely new form factor" and expressed genuine anticipation for the Japanese launch. That's not because Samsung ran a flashy marketing campaign in Japan. That's because a veteran technology journalist gave them a device that actually delivered on what multi-folding phones have promised.
For creators and business professionals who juggle tablets and laptops, Yamane doesn't mince words: "Galaxy Z TriFold can handle most tasks on its own." But he also gets that this isn't just for productivity warriors. The appeal extends to anyone who wants an immersive 10-inch viewing experience without carrying a tablet. That's the real market opening Samsung is targeting.
Where does this take mobile innovation next? Yamane sees the Galaxy Z TriFold as proof that Samsung has "comprehensive technological capabilities across both hardware and software" - and that this device "points to what's next in mobile innovation." For a guy who's reviewed thousands of phones, that's not casual praise. It's recognition that multi-folding isn't a gimmick; it's where the category is headed.
Yamane's pilgrimage to Korea for the Galaxy Z TriFold isn't about fandom. It's a vote of confidence from someone who's seen every form factor mobile has thrown at the market since the early 2000s. When a 20-year veteran with 1,800 phones in his collection calls something "entirely new," and then shows it to 100 people who universally recognize it as category-shifting, you're looking at genuine innovation. Samsung isn't just iterating on foldables anymore; they're redefining what a pocket-sized computing device can be. The real question isn't whether this device is compelling - Yamane's willingness to fly to Korea answers that. The question is whether the market is ready for what comes next.
