These MWC Phones and Gadgets Wowed Me, but Where Are They Now?

From AI hardware to wearable phones, these products promised a lot. So what happened to them?

Mobile World Congress sees the biggest and best tech companies, the world over, gather in Barcelona to show off their latest, greatest products. MWC 2026 runs March 2 to 5 and we expect to see several major phone launches, some wild concepts and a lot of tapas. But what about products we saw in prior years?

From Samsung’s flagship Galaxy S phones to incredible hardware from Xiaomi, we’ve seen some amazing devices in the years CNET has been attending the show. But we’ve also seen a lot of unusual products that have promised more than they’ve delivered.

From concept devices that are quickly forgotten to new gadgets that boast revolutionary functions, these are the MWC tech launches that arrived with a fanfare… but aren’t necessarily where you’d expect them to be today.

Humane AI pin

AI might still be the biggest buzzword in tech, thanks to every phone company cramming their devices with all kinds of bizarre AI functions. But at MWC 2024, one company wanted to take that further. The Humane AI pin was a wearable badge that you could talk to and ask questions about your schedule, the weather or things like sports results. It could read answers out and even project them onto your hand with a laser. Because everyone loves lasers.

Sounds fun, right? And the company’s rhetoric around how AI-based devices like this will replace phones sounded compelling. However, the product, well, sucked (just ask CNET’s Scott Stein, who spent extended time with it) and the company was eventually swallowed by HP, with the Pin itself ceasing to function in February last year. If you were one of the early adopters, do let us know what you’ve done with that $699(!) paperweight now.

Motorola Rizr

MWC is a great place to show off concepts that will excite technology nerds like us. Motorola has a good history of this at the show and the Rizr is one of my favorites. This phone didn’t just have a flexible display like we’ve seen on many of today’s foldable phones, its display could actually mechanically unroll at the push of a button, extending the top of the screen to give a more immersive display for watching videos or playing games.

It was amazing to see in person and it was certainly a different idea on how to use flexible displays. But that’s all it was; an idea. Motorola hasn’t deployed the Rizr’s mechanical unfurling into any of its products, with its upcoming Razr Fold launch being just a standard book-style foldable. The reason is obvious: The technology is likely expensive and probably fragile too. Three years on and Motorola hasn’t said a thing about this cool concept, but I’ll still keep my fingers crossed for this year.

Xiaomi SU7 EV

Xiaomi might be better known for its superb camera phones, but the Chinese firm has fingers in many pies, including scooters, vacuums, air fryers and, er, water pistols. It was no surprise then that during MWC 2024, the company showed off its first EV, the Xiaomi SU7. With sleek, sporty looks and a promised range of over 470 miles, I was excited.

I was excited again when the company showed off an even more performance-focused model at last year’s show, which had already delivered some blistering track times on the infamous Nürburgring. But I’ve yet to get behind the wheel. While Xiaomi is already producing and selling cars in its native China, the company has no plans to launch in the UK or wider Europe until at least 2027 and they almost certainly won’t sell in the US at all.

As a result, I feel like I’ve been teased somewhat with the promise of this slick, powerful EV that would have sat perfectly on my driveway. In reality, I still have a big wait ahead of me, if the SU7 European launch happens at all. Sales of the SU7 in China have surpassed those of the Tesla Model 3, according to a report by Car News China. Meanwhile, the same story shows that the SU7 Ultra’s sales have declined dramatically due to a number of controversies and lawsuits around the car and Xiaomi’s rollout.

Samsung Galaxy Ring

Samsung’s Galaxy Ring made for an interesting MWC in 2024. Here was a new type of wearable that promised advanced health and fitness tracking, while blending into your daily life by sitting unobtrusively on your finger. And that’s what it does, with CNET giving it a healthy 8.5 out of 10 in our full review.

But that was in 2024, and a full two years later, I’m left wondering what’s happening with the wonderful world of smart jewelry. Samsung has made no official comment around a follow-up, through rumors suggest we may see one in late 2026 or 2027. Smart ring manufacturer Oura, meanwhile, has filed a public lawsuit against Samsung and other smart ring companies claiming patent infringement. This is likely one of the reasons we’ll have to wait for a Galaxy Ring 2. While other smart rings do exist — like the Oura Ring 4 — it’s not a category that flourished after Samsung launched its ring.

There’s no Google Pixel Ring, no Apple iRing and not even an LED-infused Nothing Ring (1). Most other smart rings are made by smaller companies, such as Pebble’s recently announced $75 recyclable ring. Smart rings may have a place on our hands for a while yet, but Samsung’s lengthy delay in launching a follow-up might suggest that it’s not exactly a priority product.

Motorola wrist phone

I said that the aforementioned Moto Rizr was «one of» my favorite MWC concepts.That’s because the company’s flexible wrist phone from 2024 absolutely takes my top spot. This candybar-style Android phone had a fully flexible body that let you to wrap the whole thing around your wrist and wear it like something resembling Leela from Futurama’s wrist-mounted doodad.

I found it extremely intriguing. Here was a phone that doesn’t bulge out your skinny jeans when it’s in your pocket, but that’s also just a glance away like a smartwatch. And compared to the precision engineering required for the Rizr, the wrist phone’s technology seemed relatively achievable. After all, we already have flexible displays and this didn’t even require any specialized tiny motors — you just whack it onto your wrist like a ’90s slap bracelet.

But, like the Rizr, the wrist-mounted phone remained just a flight of fancy I experienced oh so briefly for a few days in Spain. And like any holiday romance, perhaps it’s best for me to simply remember it for what it was and not spend my days pining for what could have been.

With MWC 2026 just a few days away I’m excited to see new and wild products show their face, and I’m curious to see which of them will have staying power.

Amazon Speeds Up Delivery Even More With 1- and 3-Hour Options

The retailer says the one-hour option is available in hundreds of cities, with discounted shipping for Prime members.

Same-day delivery apparently isn’t fast enough for some Amazon shoppers. The retail giant said on Tuesday it’s adding new shipping options that will get products to front doors within a one- or three-hour window.

The company said in its announcement that the one-hour option is available in hundreds of cities across the US, while the three-hour option is now live in more than 2,000 areas. Amazon’s web page at amazon.com/getitfast shows whether those options are available to shoppers for their location. More than 90,000 products will be available for those shipping windows, the company said.

For those who can’t get those services (including the author of this post, who lives between Austin and San Antonio in Texas), a message will display: «3-hour delivery is currently unavailable. Check back at a later time or shop products with Same-Day delivery below.»

Pricing for the faster delivery options is not cheap: It’ll cost you $20 for one-hour delivery and $15 for three-hour delivery for those without an Amazon Prime account, or $10 and $5 for customers who subscribe to Prime.

Last year, the company rolled out faster Amazon delivery options to 4,000 additional areas.

In a video of the podcast Learn and Be Curious with Doug Herrington, hosted by Amazon’s CEO of worldwide stores, Kandace Kapps, the director of the company’s same-day strategy team, spoke in more detail about the challenges of fast shipping. Kapps discussed shifts in customer buying habits over the last few years, such as more people buying household essentials like toilet paper on Amazon.

She said that Amazon can deliver so quickly by placing same-day delivery hubs close to customers in metro areas and by getting products ready to ship within 15 minutes, aided by warehouse robots.

«I think customers are going to continue to get magically surprised by how fast we can deliver to their doorstop,» Kapps said.

Herrington said fast shipping increases sales: «When we speed up the service, the probability that somebody buys a product from us goes up.»

Other retailers, including Walmart, have been adding same-day delivery options or exploring other ways to speed up shipping times to compete with Amazon.

Removing buyers’ moments of hesitation

Part of Amazon’s strategy, which has involved a massive buildout of locations, deployment of thousands of trucks, deals with other delivery services and investment in logistics software, is actually pretty simple: being there when people need last-minute items or make impulse buys.

«It’s about removing the last moment where you would’ve reconsidered the purchase,» said Stephanie Carls, retail insights expert at coupon and promotional-code website RetailMeNot, a sibling site of CNET. «It changes how you shop, not just how fast you get things.»

Carls said that Amazon’s super-fast delivery is removing the timeframe when people might change their minds about a purchase.

«There used to be a gap between deciding to buy something and actually having it. That’s when you’d price check, rethink it, or decide you didn’t need it after all,» she said. «This closes that gap.»

The retail expert said that competitors, including Walmart and Target, have been speeding up delivery times in some markets. Still, they’re not matching Amazon’s scale or product range at those speeds or levels of consistency.

«And that’s what starts to make everyone else feel slow,» Carls said. «Amazon’s advantage is how tightly connected its technology, inventory and delivery networks are, which makes this level of speed more repeatable.»

Dog Health Goes Digital With New AI Chatbot

Fi Intelligence allows you to ask questions of a specially tailored pet health chatbot, but it’s not meant to replace vet visits.

It might be time to rethink what it means to be sick as a dog. On Tuesday, Fi, a smart pet technology company, announced a new AI-powered chatbot to help owners stay on top of their dog’s health using a blend of personal information and generalized dog breed data.

The AI agent, which the company is calling Fi Intelligence, is integrated directly into the Fi app. It has access to all the information gathered about your dog across the entire suite of Fi products, including the Fi Series 3 Plus and Fi Mini dog collars, as well as information and documents uploaded by the pet owner. The service is for dogs only (not cats, rabbits or other pets).

If you already own a Fi smart collar, existing data will be incorporated into the AI agent’s dataset to help it answer your questions.

When creating Fi Intelligence, the company identified a multitude of common questions that dog owners have, including whether their animal friend is walking or sleeping enough, or scratching more than usual. The chatbot was created to help owners find answers to these questions quickly and easily, according to Fi.

Fi designed its agent to answer these questions using a mix of general information about a dog’s breed, personal information and biometric data gathered by Fi smart pet collars.

Pet owners can ask the chatbot questions in plain English and get back detailed responses. Fi Intelligence is equipped to answer general questions, contrast your dog’s current data to previous time periods and compare your dog’s data to other dogs of the same breed.

Fi says its chatbot is different from general-purpose AI agents because it has been trained on a proprietary dataset containing «the largest repository of real-world canine activity, sleep and behavior data in the world.»

Fi Intelligence doesn’t replace a trip to the vet — and the company stresses it’s not supposed to. Rather, the agent is supposed to grant owners «informed confidence» about their dog’s health and can help them «show up [to the vet] with specific, documented observations drawn from weeks of continuous data.»

«The strongest signal from our beta was that owners aren’t using this to replace their vet,» said Fi’s Vice President of Product Darrell Stone. «They’re using it to show up better prepared.»

According to Fi, the Fi Intelligence integration will provide the most complete dog health profile available in the app so far. Fi Intelligence is available to all Fi members immediately.

Nvidia Teases DLSS 5 and Gamers Aren’t Impressed

The new AI technology is making some big changes to video game graphics that hardly anyone seems to like.

Nvidia opened its GTC conference with a keynote by CEO Jensen Huang, revealing the company’s latest tech. Among the raft of the company’s AI developments, gamers were treated to the imminent version of its AI-powered upscaling and optimization technology, DLSS (Deep Learning Super Sampling), touted as the «biggest breakthrough in computer graphics».

Nvidia published a video illustrating how DLSS 5 can enhance graphics in Resident Evil Requiem, Starfield and other games, showing before-and-after takes. But gamers weren’t thrilled. In fact, the response to DLSS 5 resembles more of a collective backlash, replete with memes, ridicule and outrage.

Gamers were quick to point out that DLSS 5 transformed the original graphics into something vastly different. Some called the visuals «AI slop» because they look like «yassified» AI-generated filters.

Many worry that DLSS 5 could deviate from a creator’s specific artistic vision. Critics also fear that if this technology becomes the industry standard, video game graphics might start to look the same, losing their unique visual identity.

«Everything about this is a betrayal of these game’s artistry,» said YouTuber The Sphere Hunter in a post on X Monday. «Painting over handcrafted, intentional 3D art with shiny, wrinkly, sunken-in, porous, puckered, fraudulent, filtered nonsense is deeply disrespectful. If you want this, just watch gen-AI videos all day.»

Countless memes mocking the tech’s exaggerated features flooded the internet. Others on social media parodied the effects DLSS 5 could produce in other games.

Ok, you convinced us, NVIDIA DLSS 5 is coming to «Copycat» too 😅 pic.twitter.com/WT2qRRz9EC

In a Q&A on Tuesday, Huang addressed the backlash from gamers, calling them «completely wrong.» Huang underlined that DLSS 5 «enhances and adds generative capability, but it doesn’t change the artistic control» and that «it’s in the direct control of the game developer.»

The team at Digital Foundry, which specializes in game technology and hardware reviews, called it «disruptive and transformative» but was generally positive about it, though they saw some hiccups.

«[The images] looked a little bit uncanny, I would say, but definitely the overall portrayal of those characters is much more sophisticated,» said Oliver Mackenzie, video producer and writer for Digital Foundry.

Bethesda’s official X account replied to comments from members of Digital Foundry about Starfield and The Elder Scrolls IV: Oblivion Remastered, both published by Bethesda.

«This is a very early look, and our art teams will be further adjusting the lighting and final effect to look the way we think works best for each game. This will all be under our artists’ control, and totally optional for players,» the publisher said.

DLSS 5 is set to be released sometime in the fall.

What is DLSS?

Nvidia first released its DLSS tech back in 2018 with its RTX 2080 card: The RTX architecture introduced the Tensor cores, which are essential for accelerating the calculations used by the DLSS AI. The deep learning technology was designed to upscale images and video from low resolution in real time to achieve higher frame rates.

Gamers weren’t impressed at first, but later versions of the technology did perform better in games that supported it. DLSS 4, released last year and tweaked to 4.5 as of January, made significant improvements to detail rendering, reducing motion artifacts, boosting frame rates, and generating more realistic lighting via path tracing (which incorporates interactions with ray-traced lighting).

What does DLSS 5 do?

DLSS 5 works a bit differently than previous versions of the technology. According to Nvidia, DLSS 5 shifts from processing simple pixels to understanding 3D elements. By deconstructing characters into specific components — such as skin, hair and clothing — the AI can render them more consistently. This results in faster performance and much more realistic details, especially for textures and lighting.

Game developers control how DLSS 5 enhances images and to what degree, ensuring it matches the game’s aesthetic. The demo video showcased some positive enhancements, but others looked like sweeping changes to the characters and the environment.

Which games will support DLSS 5 at launch?

On Monday, Nvidia released a list of games slated to support DLSS 5:

AION 2
Assassin’s Creed Shadows
Black State
Cinder City
Delta Force
Hogwarts Legacy
Justice
Naraka: Bladepoint
NTE: Neverness to Everness
Phantom Blade Zero
Resident Evil Requiem
Sea of Remnants
Starfield
The Elder Scrolls IV: Oblivion Remastered
Where Winds Meet

What cards will support DLSS 5?

Nvidia has yet to provide a list of GPUs that will support the new technology. In an FAQ, the company says it will release a list of supported cards closer to its release.
