Editors' Note: CNET's editors were able to purchase the Galaxy Z TriFold, and are posting an ongoing review with early thoughts, videos and image comparisons. You can check that out here.

Although the Samsung Galaxy Z TriFold looks like a smash hit already in South Korea and quickly sold out after going on sale in the US for $2,900, I've been skeptical of the foldable phone's design. But those thoughts changed considerably after I actually got my hands on it.

On paper, it looked like the Korean company was trading functionality for durability, resulting in another two-in-one foldable device rather than a true all-in-one trifold phone like the Huawei Mate XT. However, I spent 20 minutes using and folding the Z TriFold at a Samsung store in Dubai, and even that brief interaction was enough to put my skepticism to rest.

The Samsung Galaxy Z TriFold is essentially a wide-screen tablet that folds into a phone to fit inside your pocket. It might seem like a simple concept, but Samsung made several smart design decisions here that make the Z TriFold better than the rivals.

Samsung designed the foldable with two separate hinges of different sizes in order for its 10-inch screen to fold twice. The right hinge is similar to the one found on the Galaxy Z Fold 7, but the left hinge is wider and accommodates the thickness created by two of the three sections being stacked on one another when closed. The wider right hinge felt like a spring and popped open as soon as I started to unfold it. This responsiveness gives the Z TriFold a distinct ergonomic advantage when unfolding the device.

The Samsung Galaxy Z TriFold is divided into three panels (hence the name). The right-most panel is actually slightly wider than the rest, creating an edge that protrudes slightly when folded. That edge makes unfolding the phone significantly more intuitive as it's easy for my finger to find and push open. I struggled to unfold the Huawei Mate XT, the flat-sided Galaxy Z Fold 7, as well as the Honor Magic V5 with its curved sides. In contrast, the TriFold's protruding edge gives me a solid lip that makes it breeze to open.

Initially, I didn't take Samsung's announcement blog post seriously when I read that the "folding mechanism has been precisely engineered for easy opening and closing, with an auto-alarm alerting the user of incorrect folding." But in practice, the auto-alarm is shrewdly implemented and essential to this design. It makes the TriFold difficult for a person to fold incorrectly.

Three panels and two hinges mean the existence of not one, but two screen creases. Some people just can't get past having a crease on their phone's display, especially since it can become more conspicuous the more you fold it. I couldn't feel either crease when running my finger across the Z TriFold's screen. Comparatively, I can distinctly feel both creases on my Huawei trifold's display. Samsung surprised me earlier this year with its overhaul of the Galaxy Z Fold 7's hinge design, which, by consequence, minimized the depth of the crease on its folding screen. It seems that Samsung took those learnings and applied them to the Galaxy Z TriFold.

Like the Fold 7, the crease appears virtually non-existent on the Galaxy Z TriFold unless you're looking at it from an extreme angle. It likely won't bother most people, even when using the phone unfolded in wide-screen tablet mode. Overhead room lighting might reflect on the Z TriFold's screen and creases in a way that might bother some people.

Samsung vs. Huawei: Two distinct trifold designs

Samsung and Huawei have taken two different approaches to their TriFold phones. I find Huawei's Z-shaped design to be more flexible than its Samsung U-shaped counterpart in terms of pure functionality. Huawei opted for a single screen that converts into three distinct form factors: a smartphone, a mini-tablet (one side unfolded), and a wide-screen tablet (both sides unfolded).

In comparison, Samsung skips the mini-tablet design entirely. The Galaxy Z TriFold can be either fully folded or fully unfolded. If you unfold the Galaxy TriFold just once, it won't allow you to use it for anything. And that limits its usefulness.

After using the Huawei Mate XT full-time, I hoped that Samsung's Z TriFold phone would be a similar all-in-one device. I love using the Huawei trifold as a book-style mini tablet (with just one side open) for reading and browsing on commutes. But I won't be able to do that with the Z Trifold. Samsung's choice limits versatility, but it could be a massive win for durability. 

Huawei's soft folding display is exposed at all times, whereas Samsung's design protects the inner screen when it is folded shut. It's a calculated trade-off: durability in the long-term at the expense of not having a mini-tablet mode (one side opened). I am not in favor of it. However, I want any device that I'm paying $3,000 for to last as long as possible, so I welcome the durability.

Then there are the software differences between the two trifold phones. The Mate XT's operating system runs smoothly enough, but its UI looks dated. I have to jump through hoops to install the Google Play Store on the Huawei trifold. So it was refreshing to use the new Samsung TriFold by comparison, which runs Android 16-based One UI 8. The software is clearly optimized for the Z TriFold's massive canvas. It lets you run three windows side by side and add multiple pop-up windows for the ultimate form of multitasking. It also allows you to create separate workspaces (similar to Desktops on MacOS and Windows) with just two taps.

Magnets could've been useful

The Galaxy Z TriFold doesn't have a built-in kickstand (think Nintendo Switch) or support for Qi2.2 magnetic accessories (like Apple's MagSafe). And not having either makes it a challenge to work on it as a wide-screen tablet. Samsung should've included MagSafe-like magnetic accessory support so I could add a magnetic stand (think PixelSnap Ring) and easily prop it up. Then I could pair the Z TriFold with a mouse and keyboard to use like a two-in-one laptop.

If you want to use the Z TriFold's 10-inch screen as a tablet and be productive, you need a kickstand. Without built-in magnets, you're forced to find a case with a kickstand, which will inevitably make an already thick phone unwieldy. A snap-and-go magnetic stand would have been the perfect solution.

After my brief time with Samsung's newest foldable, I have to say that the Galaxy Z TriFold is a promising device -- one that might surprise a lot of people. I wish it were thinner when folded closed, but Samsung's smart design choices have me excited for the future of folding phones.
