If nothing else, the AI Pin sets the stage for this conversation, and whether it succeeds or fails, its bold approach may serve as a template for successors in wearable AI tech. Could this be the beginning of a new category of devices? Only time, and sales figures, will tell. For now, it’s certain that the AI Pin marks a fascinating turn in tech innovation.

redemption arc: the OnePlus watch 2

The OnePlus Watch 2 represents a compelling example of what happens when a tech company actually listens to consumer feedback and takes innovation seriously. After the lukewarm reception and criticism of the original OnePlus Watch, the company embarked on a path of redemption—one that culminates in this year’s smartwatch offering. With a mix of premium hardware, improved software, and a focus on efficiency, the OnePlus Watch 2 is poised to compete with the best in the wearables market.

One of the first things you notice about the OnePlus Watch 2 is its build quality. The watch case is constructed from stainless steel topped with sapphire crystal, materials that ooze durability and elegance. This premium feel is complemented by its eye-catching 1.4-inch AMOLED display, which offers vibrant colors and crisp resolution. Two side pushers add to its visual appeal, not just as buttons but as design accents, lending the watch a splash of asymmetry that feels intentional rather than chaotic. It’s an attention-grabbing accessory, whether you’re at the gym or out for a formal dinner.

But the real news is in the software upgrade. The first OnePlus Watch ran on a custom RTOS (Real-Time Operating System), which was often criticized for limited app support and lackluster performance. This time, OnePlus has turned to Wear OS 4, Google’s latest smartwatch operating system. This shift alone corrects one of the most glaring issues of its predecessor, offering a richer app ecosystem and tighter integration with Android devices.

Under the hood, the OnePlus Watch 2 packs significant technological improvements. The device runs on the Snapdragon W5 platform, Qualcomm’s dedicated chip for wearables, which delivers greater efficiency than its predecessors. Alongside this is an ultra-low-power co-processor that handles simpler tasks like tracking steps or calculating calorie burn. This dynamic division of labor allows the primary processor to stay dormant during non-demanding activities, effectively extending battery life.

And the results speak for themselves: this smartwatch boasts a solid three-day battery life with heavy usage. That means constant activity tracking, notifications, and even extended usage of its GPS functionality don’t have you reaching for the charger every night—a notable achievement in the usually power-hungry Wear OS category. For lighter users, OnePlus claims you could push it to nearly a week on a single charge.

Key features of the OnePlus Watch 2 include:

• Advanced Health Monitoring: Includes SpO2 (blood oxygen) monitoring, a heart rate tracker, and stress management tools.
• Comprehensive Fitness Modes: Tracks a wide range of workouts, from yoga to swimming, with automatic activity recognition for select sports.
• Fast Charging: Warp Charge support allows you to get a full day’s power in just 10 minutes of charging.
• Customizable Watch Faces: Choose from a variety of customizable faces, ensuring the device matches your personal style.
• Water and Dust Resistance: IP68 certification means it can survive submersion and daily wear-and-tear with ease.

These features paint a picture of a smartwatch designed for both casual users and fitness enthusiasts, with attention to details that address common consumer pain points. However, the Watch 2 isn’t without quirks. For instance, despite having a rotating crown, it remains functionally limited—spinning it has no effect on navigation or UI interaction, which feels like an oversight. Wear OS’s UI is full of swipe and touch gestures, but neglecting the crown’s potential seems like a missed opportunity to elevate usability.

Priced at 9, the OnePlus Watch 2 occupies the middle ground, making it accessible to a broad range of users while maintaining premium appeal. While it may not directly compete against luxury offerings like the Apple Watch Series 9 or Samsung’s Galaxy Watch 6 in terms of raw ecosystem dominance, it certainly carves out a strong niche for itself in terms of value for money. By combining good hardware, reliable software, and long battery life, this smartwatch has the potential to attract users who may have been disillusioned by the brand’s first attempt.

One particularly exciting aspect is Google’s recently introduced architecture for Wear OS, which forms the backbone of the OnePlus Watch 2 experience. This updated architecture emphasizes efficiency and smart use of co-processors to lighten the load on the main chip—ensuring longevity without sacrificing performance. It’s a promising development that could bode well not only for OnePlus but for the entire lineup of Wear OS devices moving forward.

However, how the OnePlus Watch 2 holds up in real-world scenarios remains to be seen. Wearables often live or die by details like how accurate their health tracking is, how easily they pair with various smartphones, and whether their software is free of bugs. While the smartwatch shows promise, these aspects will ultimately determine its success—or whether it serves as a mere stepping stone for future iterations.

The OnePlus Watch 2 is set to officially launch on March 4th, and for those in the market for a versatile and efficient smartwatch that doesn’t break the bank, it’s definitely worth keeping on your radar. Its blend of performance and lifestyle features marks a significant evolution for OnePlus’s smartwatch ambitions, solidifying the Watch 2 as not just a redemption story—but a genuine competitor in 2024’s wearables race.

affordable folding phones: the rise of mid-range flip devices

The rise of affordable foldable phones at MWC 2024 has sparked what could be seen as a pivotal moment in the evolution of consumer technology. Folding phones, once an extravagance reserved for early adopters willing to shell out ,500 to ,000, are finally dipping into a price range that feels attainable for the average buyer. What makes this particularly exciting is not just the accessibility but the diversity of brands stepping into the foldable market, bringing bold designs, creative features, and competitive specs to the table. This year’s MWC was buzzing with clamshell flip phones priced under 0—an incredible shift for a sector that has long been out of reach for everyday consumers.

First among the contenders is the Doogee Flip X, a product from a brand better known for rugged smartphones than cutting-edge form factors. The Flip X demonstrates how even niche players are getting in on the folding action. Its glossy exterior is undeniably flashy, but early impressions suggested refinement still eluded Doogee. The cover screen on the demo unit, for instance, wasn’t functional, which was disappointing to attendees hoping to glimpse its potential utility. Worse still, reports emerged mid-show that some demo units were removed entirely after exhibiting durability issues—a worrying sign for any handset slated for an April release. Still, Doogee’s efforts signify that companies typically associated with durability rather than innovation are keen to test the foldable waters.

On the other hand, Blackview made a more stylish play with its Hero 10. Incorporating a vegan leather back and a circular cover display, it stood out as an affordable clamshell offering some premium aesthetics. While its Helio G99 chipset anchors it firmly in the 4G realm—a limitation that carves it out of the U.S. market—it brings charm and flair to regions where 5G adoption is less pronounced. The Hero 10 doesn’t scream high-end, but much like its competitors in this price bracket, it opens the door to a demographic that previously admired folding phones only from a distance.

Then there’s the Ultimate U 660S, a flip phone from Avenir—a company better known for its licensing of the Energizer brand. While Energizer’s brand typically evokes thoughts of ruggedness and marathon battery life, this device strangely carried a lower-capacity battery than competitors like the Galaxy Z Flip5 or Motorola Razr. Beyond its confusing battery choices, the U 660S sported peculiar design quirks, including an oddly rounded bezel and a scratched fiberglass finish. Comparing it to mainstream clamshell options leaves one wondering whether Avenir is relying more on its brand recognition than the hardware itself.

Finally, for those looking to step into the foldable future at the sweeter end of the mid-range market, ZTE Nubia Flip 5G became a standout option. Thanks to its Snapdragon 7 Gen 1 chipset, it’s the only flip phone in the sub-0 category boasting 5G functionality. With its satin-finish edges, textured rear glass, and a well-sized circular cover screen, it’s a design-forward device that doesn’t compromise entirely on modern specs. Not only does it bring 5G connectivity, but ZTE also seems to have invested in its aesthetics, striking a balance between practicality and allure—qualities necessary for an everyday folding device.

Table: Comparison of Affordable Clamshell Foldables

While most of the sub-0 clamshells are confined to 4G connectivity and rely on mid-range specs, they unintentionally define an emerging market. Unlike flagship foldable options from Samsung and Motorola, which deliver a luxury experience, these newcomers appeal to practical buyers who crave the novelty of foldables without the substantial financial commitment.

Adding to the intrigue is their collective target market: much of the affordable flip-phone design wave is focused on developing regions and niche audiences in Southeast Asia, the Middle East, and parts of Europe, bypassing the competitive U.S. markets that are tightly held by Samsung and Motorola. The latter brands dominate North America’s mid-range through aggressive discounts on their flagship flips, which, in the eyes of many, renders low-budget clamshells relatively less appealing stateside.

• The Gap in U.S. Availability: Sub-0 foldables are unlikely to see massive releases in the U.S.; instead, manufacturers are targeting regions with less competition or where buyers are no longer enslaved to carrier deals.
• Improved Chipsets: Upgrades like the Snapdragon 7 Gen 1 on the Nubia Flip bring foldable phones one step closer to premium mid-range status without crossing the 0 ceiling.
• Diverse Designs: From leather-backed finishes to circular displays, brands are experimenting visually in ways that may ignite demand in untapped markets.

The arrival of affordable folding phones also raises an important question: Can mid-range foldables meaningfully compete against their flagship rivals in quality and innovation, or are they destined to be relegated to regional novelties? For now, the answer lies in execution. While new players are flooding the market with dazzling designs and daringly low prices, durability, software optimization, and meaningful utility still matter. Early hiccups like faulty demo units or uninspiring internals could quickly scare off potential adopters.

Still, the sub-0 foldable market feels like the first step in democratising advanced form factors. As flagship models continue to dominate the conversation, these clamshell contenders quietly carve out their own space, paving the way for what could genuinely be considered the golden era of everyday foldables.

modular innovation: hmd fusion’s open-access approach

Imagine a future where a farmer can snap on a soil monitoring module for his fields, or a student can attach a module with a pocket projector for in-class presentations. These aren’t just aspirational concepts—they’re entirely practical within the modular framework HMD is encouraging. Additionally, partnerships with brands like Mattel, which teased a Barbie-themed flip phone collaboration, suggest the potential for creative and playful integrations.

Moreover, the modular accessories could eventually integrate with Android’s ecosystem, allowing developers to create apps that seamlessly interact with the modules. For example, attaching a heart rate or blood pressure module could pair with Google Fit, automatically syncing health metrics and creating a personalized fitness dashboard. It’s a subtle way to enhance Android’s utility while giving users more control over their digital toolkit.

Challenges in Modular Adoption

As exciting as the concept of HMD Fusion is, it’s not without hurdles. Firstly, standardization will be key to its success. For modularity to truly thrive, HMD will need to ensure third-party accessories maintain a consistent level of quality and compatibility, which may require meticulous certification workflows. Additionally, while the six-pin connector offers simplicity, it likely comes with limitations in certain high-speed data transfer applications. Competing innovations, such as phones with entirely new foldable or rollable categories, could also siphon attention away from modular devices.

Cost could be another potential stumbling block. While the promise of affordability is central to HMD’s marketing, the upfront expense of modular “outfits” will need to stay in a range that feels more economical than simply upgrading to a new device. For enthusiasts, the customizability will definitely offer appeal, but casual users may still need convincing to embrace the ecosystem.

What’s Next for Modular Phones?

HMD Global plans to launch the first phone in the Fusion series in the summer of 2024, and the stakes couldn’t be higher. The initial reception will shape whether modular phones finally go mainstream or remain a niche experiment. One factor working in HMD’s favor is the increasing consumer focus on environmental responsibility—customizable, long-lasting hardware fits neatly into this narrative. Combine that with the accessibility of 3D printing and the rising familiarity of open-source ecosystems, and HMD Global might just be on the verge of tapping an unmet market need.

To ensure its success, HMD is also planning a community-wide campaign to surface the most innovative modular ideas, including contests to incentivize developers and makers. And with the Fusion devices promoting fun collaborations—like the previously mentioned Barbie-inspired flip phone—it’s clear the brand is aiming to position modularity as both practical and aspirational.

HMD Fusion’s vision represents more than just a gadget—it’s a statement against the throwaway culture enabled by modern technology. With the promise of an open-access approach that embraces consumer creativity and ecological sustainability, Fusion could finally be the modular breakthrough the tech industry has been waiting for. Whether this idea evolves into a thriving ecosystem or joins the ranks of ambitious experiments past, its goal to empower users deserves applause. It’s exactly the kind of forward-thinking innovation that exemplifies why Mobile World Congress remains a hotbed for the tech industry’s boldest ideas.

concept tech: the future of transparent and adaptive displays

There’s something undeniably mesmerizing about gazing into a transparent display, a kind of sci-fi spectacle where the boundaries between reality and technology intertwine.

Known for pushing the envelope in laptop innovation, Lenovo showcased a magical marriage of sleek hardware and futuristic display technology, offering a glimpse into what could soon redefine how we interact with visual interfaces in our daily lives.

The prototype, a hybrid laptop, incorporates a micro-LED transparent display sandwiched between two layers of glass. The transparency is awe-inspiring, revealing either a complete see-through view of what’s behind the laptop or a subtle layering of content that seems to float in mid-air. Currently capped at a resolution of 720p, Lenovo describes the display as a work in progress. The company hopes to improve both the image quality and integrate features that allow users to adjust the opacity to conceal the screen when privacy is needed—a variation illuminating key business and personal applications.

Why Transparent Displays?

At first glance, some might ask the inevitable question: why does this matter? Transparent displays are not just about aesthetics. They symbolize the next step in decluttering our visual environment, creating layers of interactions that go beyond staring at opaque screens. For instance:

• Contextual Information Overlay: Imagine working in front of your window overlooking the city skyline, while your productivity dashboard seamlessly blends into the landscape. Transparent displays offer a more natural user experience that doesn’t cut off the external world.
• Retail and Marketing Applications: Conceptual uses for glass storefronts and interactive kiosks could fundamentally reshape customer interactions, displaying advertisements or inventory data while maintaining visibility of the physical space behind them.

Challenges and Potential Solutions

While the allure of a transparent display is undeniable, the technology is not without its hurdles. For one, ambient light interference becomes a significant challenge. Traditional displays are optimized for controlled environments, but transparency introduces exposure to surrounding lighting conditions, which could compromise readability. Lenovo’s engineers hinted at leveraging high dynamic contrast ratios and adaptive brightness settings to mitigate these issues, ensuring the screen remains visible without sacrificing clarity.

Another pressing concern lies in hardware durability. Transparent displays require ultra-precise engineering to minimize distortions across the glass’ surface and maintain thinness without compromising robustness. Lenovo’s demonstrator employs reinforced glass and protective polymer finishes, ensuring the device survives standard consumer mishaps. Overcoming these engineering hurdles will be key to bringing such technology to market on a mass scale.

Finally, there’s the question of cost. Cutting-edge innovations like this rarely start at consumer-friendly prices, prompting speculation about whether transparent displays will cater initially to luxury or niche markets. However, with growing competition in micro-LED production, economies of scale could rapidly accelerate pricing parity with standard screen technology. This mirrors the trajectory we saw with OLED and AMOLED displays, which are now mainstream across numerous product categories.

Future-Forward Scenarios

The most exciting aspect of Lenovo’s transparent laptop display is not just the technology itself, but the door it opens to a plethora of new use cases. Couple this with other innovations unveiled at MWC—adaptive, rollable, and even holographic displays—and you begin to imagine just how versatile future devices might become. Here are just a few ideas:

• Dual-Pane Workspaces: Professionals using transparent screens could overlap two display zones—one showcasing a live team collaboration session and the other an unobstructed view of physical documents or reference material behind the screen.
• Wearable Integration: Transparent display tech could eventually work alongside wearable AR/VR glasses, allowing seamless transitions between the virtual and physical worlds.
• Enhanced Automotive Experiences: This concept aligns well with automotive heads-up displays (HUDs), potentially allowing clear navigation data overlaid directly on the windshield without obstructing the driver’s field of view.

The Motorola Connection: Adaptive Displays with a Twist

Interestingly, Lenovo wasn’t the only player dancing with display innovation at MWC 2024. Motorola, now a Lenovo subsidiary, unveiled another spectacular concept: an adaptive display that bends “the wrong way.” Unlike its foldable Razr phones, this device dynamically shapes itself as needed. Whether it’s curved into a cuff to be worn as a bracelet or bent back into a minimalistic scrolling mode, Motorola’s adaptive display blurs the lines between wearables and traditional handheld devices. The bendable form factor even allows users to prop it into a tent mode for collaborative board gaming or interactive whiteboarding sessions.

This might evoke skepticism—after all, flexible screens have been finicky and fragile in their early stages of development. Still, 312 Labs, Motorola’s experimental division, had one compelling response: magnets. Embedded within the flexible display are modular magnetic connectors that allow the device to attach to various surfaces or accessories securely. A quick magnetized bracelet turned the device into a personal fitness tracker, while another automotive dock transformed it into a hands-free navigation assistant.

Limitations to Overcome

The wild concept devices presented by Lenovo and Motorola will likely face a hard road to mainstream adoption. For transparent displays, the integration of opacity control and enhancements in resolution remains critical. Content creators and business users, for instance, want devices that adapt effortlessly to diverse scenarios—from showing a client presentation to watching streamed content privately during downtime.

Similarly, durability concerns loom large over adaptive and bendable displays. Whether it’s through clever engineering, material upgrades like Gorilla Glass Victus or similar resilient polymers, these must handle bending and tapping without succumbing to wear.

Setting the Stage for Tomorrow

Lenovo and Motorola’s experiments might only be scratching the surface of what flexible and transparent displays can offer. As technology like touchless sensors, OLED optimization, and edge-to-edge wireless charging becomes intertwined with these concepts, they could radically redefine the traditional laptop or smartphone experience.

This boils down to one idea: we’re heading toward a tech future where hardware becomes an almost invisible companion to our lives—working with, rather than distracting us from, our environments. Transparent and adaptive displays reflect this philosophy in more ways than one. While practical implementation lags behind theoretical capability, these devices hint at what could be a more organic, unobtrusive relationship with our machines. At MWC 2024, the revolution wasn’t televised—it was see-through.
