Samsung Galaxy Z TriFold Hands-On: This May Be the Phone-Tablet Hybrid We’ve Been Waiting For

I checked out the new foldable at CES, and it feels like a wildly practical two-in-one device, thanks to its massive display and overall sleek build.

I’ve tested my fair share of thin and foldable phones over the years, but something about Samsung’s Galaxy Z TriFold struck me as particularly notable when I held it for the first time at CES 2026 in Las Vegas on Sunday.

At last, it seems foldables are approaching their long-desired goal: a two-in-one device that fits neatly in your pocket.

The trifold — which technically folds twice but has three panels — feels like a true phone-tablet hybrid that stands well apart from its bar-style counterparts. Its value appears to lie less in flashy specs about its thinness and more in its utility and practicality.

Yes, the Galaxy Z TriFold feels impressively sleek when open: It’s just 3.9mm at its thinnest point and 4.2mm at its thickest, not accounting for the camera bump. It feels wonderfully normal in my hands, to the degree that I didn’t really think about its weight of 309 grams as I used it. But the trifold doesn’t inspire the same awe as Samsung’s book-style Galaxy Z Fold 7 or the bar-style Galaxy S25 Edge, which primarily lean on showcasing an ultra-thin, lightweight design.

Instead, the Galaxy Z TriFold is all about getting things done on a portable scale. Need to shoot off a quick text or check an email? The 6.5-inch cover display feels remarkably close to using a non-folding phone — minus the slightly chunky 12.9mm thickness when the trifold is closed. And when it’s time to watch a movie, multitask or type up a paper, the expansive 10-inch internal display offers plenty of real estate.

That duality makes the Galaxy Z TriFold feel like a true hybrid device that can fill a niche that book-style foldables have yet to satisfy, despite their many efforts.

Comparing the Z TriFold and the Z Fold 7 at a glance

Placing Samsung’s Z TriFold and its two-panel Galaxy Z Fold 7 side by side underscored just how different each phone is.

Yes, you can watch videos at a larger scale on the Z Fold 7’s inside display, but that experience pales in comparison to the true tablet-like feel of the unfurled Z TriFold. You can open up to three apps simultaneously on both phones, but doing so on the trifold feels like less of a compromise thanks to its bigger screen. And with Samsung DeX, turning your phone into a mini computer of sorts has never felt more practical, since there’s more room to work with.

One of the biggest indicators of how far foldables have come is the fact that both the Z TriFold and the Z Fold 7 pack pretty impressive cameras: a 200-megapixel wide, 12-megapixel ultrawide and 10-megapixel telephoto camera on the back, along with two 10-megapixel selfie cameras. So if you’re choosing between the larger and smaller Samsung foldables, that’s one key factor they have in common.

Two hinges on the trifold means double the screen creases, but they’re thankfully less visible than the Z Fold 7’s, which is already pretty subdued. Learning how to close the trifold correctly can be a bit of a learning curve, especially if you’re right-handed like me; you’ll need to close the left panel first. But each time you (I) mess up, the phone gives haptic feedback and an alert that you (we) are doing it wrong, which is helpful.

What’s perhaps most assuring is the trifold’s 5,600-mAh battery, which can hopefully allow the phone to power through a full day’s use, and then some. The Z Fold 7 has a 4,400-mAh battery, which lasted all day in my initial testing, but without much juice to spare. Hopefully, the Z TriFold remedies that. The trifold’s 45-watt super-fast charging is a nice perk, too.

Speaking of charging: Samsung told me the Z TriFold will come with not just a charging cable in the box, but also a charging brick. Nature is healing.

US release and price

The Z TriFold is already available in Korea, China, Taiwan, Singapore and the United Arab Emirates. In fact, my colleague Prakhar Khanna beat me to the punch and got his hands on the phone in Dubai last month.

Samsung has said the Z TriFold will launch in the US in the first quarter of this year. It’ll be interesting to see if people in the US respond similarly to those in other countries like Korea, where the phone reportedly sold out in minutes.

Another looming question remains: the price. Samsung didn’t share the US price at CES, but we’ll likely learn more as we approach the (also unknown) release date. Given the Z Fold 7’s $2,000 price tag, though, you might want to start saving up now.

Yes, This Swimming RoboTurtle Is Adorable. It Also Has an Important Environmental Mission

Beatbot is best known for making pool-cleaning robots, but it was its swimming robot turtle that won our hearts at CES 2026.

Few things in life have made me feel more privileged and awestruck than the opportunity to swim with sea turtles in their natural environment. The way in which these gentle creatures navigate through their underwater world with their deliberate and careful fin strokes is utterly mesmerizing to watch.

It’s a distinctive style of movement — so much so that when I saw Beatbot’s RoboTurtle swim across a water tank on the show floor at CES 2026, I knew that this wasn’t simply just a pool cleaner robot with turtle features tacked on. This was a studied example of biomimicry in action.

The reason for this is that the company’s engineers went on a two-month expedition to study sea turtles in their natural environment, Beatbot’s Eduardo Campo told me as we watched Turtini (the team’s affectionate nickname for RoboTurtle) splash around in its pool. «We did a lot of motion capture, like the things they use in movies, because we need to develop those joints that it has,» he said.

This isn’t RoboTurtle’s first time at CES — it also appeared in 2025 as a static concept. This is the year, however, it’s found its fins, so to speak. Not only can it swim, but it can also respond to hand gestures: I throw it an OK gesture, and it dances in response. But as cute and limber as it is, RoboTurtle is a robot with an important mission.

RoboTurtle is an environmental research tool, built with input from researchers and NGOs, which can go where humans or other machines cannot for fear of disturbing complex and delicate underwater ecosystems, particularly coral reefs. It can move silently and naturally in a way that won’t scare wildlife, monitoring water quality and fish numbers with its built-in camera.

«One of the groups that we’re working with, they want to study the coral reefs in near Indonesia,» said Campo. «There was a very big incident over there with a boat that came up onto a coral reef and it disrupted the environment, [so] they want the least intrusive robot possible.»

The group wants to deploy RoboTurtle for certain periods every year to monitor the recovery of the coral and monitor the fish population, he added. Beatbot is currently training the built-in AI to give RoboTurtle monitoring and recognition skills.

At CES, I watched RoboTurtle paddle about only on the surface of the pool, but it can also dive down up to five meters. However, it needs to resurface to send data and its GPS signal back to base, much like a real turtle that needs to come to the surface to breathe. This also gives it a chance to recharge via the solar panel on its back.

Even though I was impressed with RoboTurtle’s swimming ability, Campo estimates that the Beatbot team is still a year and a half away from perfecting its technique, with the robot ready for full deployment in between three to five years.

CES 2026 is a show where tech with a real purpose feels scarce, so it sure is refreshing to see a company use its expertise to build something designed with a sustainable future in mind. It might be a while until we see RoboTurtle take to the seas, but I’m glad that I got to witness it at this stage of its journey.

These Tiny Robots Are Smaller Than Grains of Salt and Can Think, Move and Swim

Despite their size, the robots can navigate liquids, respond to their environment and operate without external control.

Robots smaller than a grain of salt? It sounds like science fiction, but researchers have developed autonomous microrobots that can move through liquids, sense their environment and operate independently using only light as a power source.

The microrobots, developed by researchers at the University of Pennsylvania and the University of Michigan, measure roughly 200 by 300 by 50 micrometers. Yet they can detect temperature changes, follow programmed paths and function independently for months at a time.

Their work was reported this week in two scientific journals, Science Robotics and Proceedings of the National Academy of Sciences.

«We’ve made autonomous robots 10,000 times smaller,» senior author Marc Miskin, assistant professor in electrical and systems engineering at Penn Engineering, said in a statement. «That opens up an entirely new scale for programmable robots.»

Powered entirely by light, the robots don’t move using mechanical limbs. Instead, they generate tiny electrical fields that push ions (electrically charged particles) in fluid to create motion, an approach better suited to the unique physics of the microscopic world, where traditional motors don’t work.

Unlike earlier microrobots, these devices combine sensing, computing, decision-making and movement in a single, self-contained system at an extremely small scale.

Previous efforts in microrobotics have often relied on external controls, such as magnetic fields or physical tethers, to guide movement. These new microrobots, however, incorporate their own miniature solar cell-powered processors, allowing them to respond to their environment, communicate through patterned movements visible under a microscope and carry out tasks without outside direction.

Potential applications include monitoring biological processes at the cellular level, supporting medical diagnostics or helping assemble tiny devices. Because each robot can be mass-produced at very low cost, the technology opens new avenues for research and engineering at scales that were previously unreachable.
