Samsung is working on a pair of new foldable smartphones to follow its Galaxy Fold, a smartphone with dual screens that fold in half like a notebook, and another that works just like any other. Bloomberg reports: The South Korean manufacturer is said to be developing a clamshell-like device, and another that folds away from the user similar to Huawei's Mate X, people familiar with the matter said, asking not to be identified discussing internal plans. The $1,980 Galaxy Fold that Samsung plans to release in April folds inward like a notebook. While it's still too early to gauge how much demand there will be for smartphones with flexible screens, Samsung and other rivals are eager to gain an edge over Apple Inc. in the $495 billion industry, especially amid cooling sales.

Samsung plans to unveil the vertically folding phone late this year or early next year, and is using mock-ups to fine-tune the design, the people said. The gadget is designed with an extra screen on the outside, but the manufacturer may remove it depending on how customers respond to a similar display on the Galaxy Fold, they said. The outfolding device, which already exists as a prototype after being considered as Samsung's first foldable gadget, will roll out afterward, the people said. It will be thinner because it has no extra screen, they said. Samsung may also incorporate an in-display fingerprint sensor for its foldable lineup, as it did for the Galaxy S10 model announced last month, they said. The report also touched on the Galaxy Fold's screen imperfection. Apparently, a crease "appears on the panel after it's been folded about 10,000 times, and Samsung is considering offering free screen replacements after releasing the product."

"The Galaxy Fold's screen imperfection develops on a protective film covering the touch sensor bonded with the display underneath," the report adds. "That's one reason why Samsung kept the phone inside a glass case at MWC in Barcelona last month."

Microsoft is officially killing off its Microsoft Band and Microsoft Health Dashboard apps and services on May 31st. "The software giant already discontinued its wrist-worn Band fitness tracker more than two years ago, but the company has kept the Band apps running to support existing users," reports The Verge. "That will now change on May 31st, with the backend services ending and the apps being removed from the Microsoft Store, Google Play, and Apple's App Store." From the report: Existing Band users will be able to export their data before the end of May, and services powered by the cloud will cease to function in June. Band users should still be able to record daily steps, heart rate, and workouts, alongside activity data, sleep tracking, and alarm functionality. If a Band user resets a device then it will be "impossible to set up the device again" according to Microsoft.

Some Microsoft Band users will be eligible for a refund from the software giant, though. Microsoft is letting active users who have synced data from a Band to the Health Dashboard between December 1st 2018 and March 1st 2019 apply for a refund on their hardware. Surprisingly, Microsoft is offering $79.99 for Band 1 owners, and $175 for Band 2 devices. If your Microsoft Band is also covered under warranty, the same refund values will be available.

Microsoft CEO Satya Nadella is defending the company's $479 million contract with the Pentagon to supply augmented reality headsets to the U.S. military. "We made a principled decision that we're not going to withhold technology from institutions that we have elected in democracies to protect the freedoms we enjoy," he told CNN Business at Mobile World Congress. "We were very transparent about that decision and we'll continue to have that dialogue [with employees]," he added during the exclusive interview. From the report: Microsoft was awarded the contract to supply "Integrated Visual Augmentation System" prototypes to the U.S. military in November. The company could eventually deliver over 100,000 headsets under the contract. Microsoft's HoloLens augmented reality technology allows users to see the world around them, but with virtual graphics overlaid. The Israeli military, which has taken delivery of some HoloLens headsets, says the technology can be used to help commanders visualize the battlefield and field medics to consult doctors. According to procurement documents, the U.S. military is seeking a single platform that provides its forces with "increased lethality, mobility and situational awareness" in combat. Microsoft employees have recently circulated a letter addressed to Nadella and Brad Smith, the company's president and chief legal officer, arguing that the company should not supply its HoloLens technology to the U.S. military. "It's not about taking arbitrary action by a single company, it's not about 50 people or 100 people or even 100,000 people in a company," he said. "It's really about being a responsible corporate citizen in a democracy."

LG's flagship G8 smartphone has been officially launched today, bringing many expected features that were teased over the past few months and several not-so-expected features. One such unusual feature in the G8 is its palm vein recognition, dubbed Hand ID, which LG claims is the first to offer this capability. TechCrunch reports: From the company's press materials, "LG's Hand ID identifies owners by recognizing the shape, thickness and other individual characteristics of the veins in the palms of their hands." It turns out, like faces and fingerprints, everyone's got a unique set of hand veins, so once registered, you can just however your hot blue blood tubes over the handset to quickly unlock in a few seconds. The Z camera also does depth-sensing face unlock that's a lot harder to spoof than the kind found on other Android handsets. LG's also put the tech to use for a set of Air Motion gestures, which allow for hands-free interaction with various apps like the camera (selfies) and music (volume control). Other features of the G8 include a 6.1-inch QHD+ "Crystal Sound OLED" display that uses the screen as an audio amplifier. There's a Snapdragon 855 processor with 6GB of RAM and 128GB internal storage, three cameras on the rear including a 16-megapixel Super Wide (F1.9), 12-megapixel Standard (F1.5), and 12-megapixel Telephoto (F2.4), a 3,500mAh battery that charges via USB-C, a headphone jack, and 32-bit Hi-Fi Quad DAC.

Artem S. Tashkinov writes: Hailed as a third wave of computing, Microsoft has made the HoloLens 2 mixed-reality headset available for preorder for a staggering $3,500 and it's expected to be shipped later this year. It will be sold only to enterprise customers. Compared to the first generation HoloLens, the second version is better in almost every important way: it's more comfortable to wear, it offers a much wider field of view, it contains powerful recognition software that can detect real world physical objects and allow you to seamlessly interact with them using hand and finger gestures. It features new components like the Azure Kinect sensor, SnapDragon 850 SoC, eye-tracking sensors, an entirely different display system with 2K resolution for each eye, a couple of speakers, and an 8-megapixel front-facing camera for video conferencing. It's also capable of full 6 degrees of tracking, and it also uses USB-C to charge.

An anonymous reader quotes a report from TechCrunch: The world's fastest growing mobile company has long had a chip on its shoulder when it comes to Apple and Samsung. For too long, the company has had to go out of its way to remind the world that it's capable of being every bit as innovative as those better established brands, a concept very much at the heart of the Mate X. The device lives right at the cross section of the year's biggest forward looking trends -- foldables and 5G, and unlike some of the concepts we've seen to date, the product does so with panache.

The device is thin, as far as tablets go, at 5.4 mm, unfolded. Closed, it's nearly double that, at 11 mm. Not thin, exactly, but still a heck of a lot easier to slip into your pants pockets than the 17mm Galaxy Fold. More impressive is what the company's been able to do with its displays. The screen is very much the thing on these products, and yet the Fold's outside screen only measures 4.6 inches. The Mate X, meanwhile, sports a pair of outward-facing displays, the larger of which measures 6.6 inches at 2480 x 1148 pixels, with a 19:5 aspect ration. The flip side is 6.38 inches, allowing for space for the camera bar -- a chin that folds over to meet the display. The system features a Leica lens and the design is such that photo subjects can see themselves on the outward-facing display as a shot is taken. On the device's side is a combo fingerprint reader/power button. The phone uses a proprietary "Falcon Wing" hinge to unfold and turn into a full 8-inch tablet. The report does note that there is "a visible crease in the middle of the phone." Inside are a pair of batteries that add up to 4,500mAh of power, as well as a Kirin 980 processor.

In a separate article, TechCrunch says the Mate X is expected to retail for about $2,600, proving that there is certainly a pricing premium with foldables and 5G phones.

Verizon is asking the FCC to let it keep new smartphones locked to its network for 60 days, as part of an initiative to prevent identify theft and fraud. "After the 60-day period, the phones would unlock automatically, the telecom says in a note published to its website and authored by Ronan Dunne, Verizon's executive vice president," reports The Verge. "Verizon says it should have the authority to do this under the so-called 'C-block rules' put in place following the FCC's 2008 wireless spectrum auction." From the report: "We believe this temporary lock on new phones will protect our customers by limiting the incentive for identity theft. At the same time, a temporary lock will have virtually no impact on our legitimate customers' ability to use their devices," Dunne writes. "Almost none of our customers switch to another carrier within the first 60 days. Even with this limited fraud safety check, Verizon will still have the most consumer-friendly unlocking policy in the industry. All of our main competitors lock their customers' new devices for a period of time and require that they are fully paid off before unlocking."

Verizon is just putting itself in line with the rest of the industry here. AT&T already requires your phone be activated for 60 days for you to unlock it, and the company even requires you to wait two weeks to unlock your old phone if you're upgrading to a new one. T-Mobile requires you wait 40 days, and also limits users to two unlocks per year per line. Sprint has a 50-day limit, and only unlocks devices from the onset if the phones are prepaid.

An anonymous reader quotes a report from BuzzFeed News: A viral photo showing a camera in a Singapore Airlines in-flight TV display recently caused an uproar online. The image was retweeted hundreds of times, with many people expressing concern about the privacy implications. As it turns out, some seat-back screens in American Airlines' premium economy class have them, too. Sri Ray was aboard an American Airlines Boeing 777-200 flight to Tokyo in September 2018 when he noticed something strange: a camera embedded in the seat back of his entertainment system. The cameras are also visible in this June 2017 review of the airline's premium economy offering by the Points Guy, as well as this YouTube video by Business Traveller magazine.

American Airlines spokesperson Ross Feinstein confirmed to BuzzFeed News that cameras are present on some of the airlines' in-flight entertainment systems, but said "they have never been activated, and American is not considering using them." Feinstein added, "Cameras are a standard feature on many in-flight entertainment systems used by multiple airlines. Manufacturers of those systems have included cameras for possible future uses, such as hand gestures to control in-flight entertainment." After Twitter user Vitaly Kamluk saw a similar lens on Singapore Airlines and tweeted photos of the system last week, the airline responded from its official Twitter account, saying the cameras were "disabled." Still, the airlines could quell passengers' concerns by covering the lenses with a plastic cover, if indeed there is no use for the camera.

Next-generation 5G networks are very much in their infancy right now, but that's not stopping smartphone manufacturers from teasing new 5G phones. At Samsung's Galaxy S10 launch event today, Samsung teased the Galaxy S10 5G, a top-tier model of the Galaxy S10 that offers 5G mobile data connectivity. "The device, which has a larger screen and battery than the S10 Plus, will temporarily be a Verizon Wireless exclusive before expanding to other carriers in the weeks after launch," reports The Verge. "It will go on sale sometime 'in the first half of 2019."

Late last year, LG confirmed that its first U.S. 5G phone would debut on Sprint "in the first half of 2019," just as Sprint launches its 5G network. At around the same time, Lenovo unveiled the Moto Z3, a phone that only connects to 5G with a MotoMod modular accessory. It too is expected to arrive early this year -- but there's no mention of how much it'll cost. OnePlus, Nokia, and Huawei are also working on 5G phones expected to arrive sometime this year. The question is: are we ready for 5G phones? Three of the four largest carriers in the U.S. have only just started offering 5G service in select cities. Sprint, the fourth largest U.S. telecommunications company, hasn't even reached this step. Just like the first 4G phones to hit the market, these first-of-their-kind 5G devices look to merely symbolize what the next decade of mobile computing has in store.

Qualcomm has unveiled its latest 5G modem, the Qualcomm Snapdragon X55. The chip is the company's second-generation 5G modem and successor to the Snapdragon X50 that was announced back in 2017. "Headline features of this new chip include multi-mode 4G and 5G in a single chip, blazing fast 7Gbps speeds, and futureproof support for the 5G Standalone specification," reports Android Authority. From the report: Starting with 5G, the chip supports both mmWave and sub-6GHz spectrum, just like its predecessor. Theoretical peak speeds are boosted from 5Gbps to 7Gbps download and up to 3Gbps upload. However, you'll need a perfect alignment of network conditions and capabilities to reach such lofty speeds. More important is the introduction of 5G FDD support. This will be crucial in Europe and other places looking to free up low-frequency spectrum (600 to 900MHz) for 5G. The Snapdragon X55 also introduces 4G/5G spectrum sharing, 100MHz envelope tracking for better power management, and antenna tuning in the sub-6GHz region. All very handy improvements over its first generation 5G modem.

Perhaps the biggest point of all is that the X55 also supports the 5G Standalone (SA) specification. First-generation 5G networks and devices are all based on the earlier Non-Standalone (NSA) specification. Eventually, these will transition over to the SA standard. SA ditches the use of LTE networks for backend communication, transitioning over entirely to 5G. This opens up greater networking flexibility with Network Slicing and offers even lower latency for IoT and device-to-device communication. On the 4G side, the Snapdragon X55 supports the Category 22 LTE standard. This allows for peak throughput of 2.5Gbps, making it Qualcomm's most powerful 4G solution to date. The Snapdragon X55 also introduces Full Dimensional MIMO (FD-MIMO) for LTE. This includes 3D beamforming, allowing for improved elevation support to improve spectrum efficiency. Importantly, the Snapdragon X55 is built on a 7nm process rather than 10nm with the X50. The new modem isn't expected to appear in devices until late 2019 at the earliest. Android Authority suggests that the X55 will be featured inside 2019's next-gen Snapdragon 8XX processor, which should be officially announced at the end of the year, close to when Qualcomm expects the first X55 products.

"In addition to the new modem, Qualcomm also announced its second-generation mmWave antenna and will be demoing its 5G technologies at MWC," reports Android Authority. "Dubbed the QTM525, the latest antenna module is slightly slimmer than the previous design and can be built into phones thinner than 8mm thick. It now covers 26, 28, and 39GHz mmWave spectrum and Qualcomm continues to suggest that three or four of these will be needed per 5G phone."

Samsung has unveiled the Galaxy Tab S5e, its lightest and thinnest tablet ever made. "At $399, it's not only far more affordable than the flagship $649 Samsung Galaxy Tab S4, it's arguably surpassed it in some ways," reports The Verge. From the report: For starters, the Tab S5e has the thinnest and lightest metal unibody of any Galaxy Tab, measuring 5.5mm thin and weighing just 400 grams -- even compared to the 11-inch iPad Pro at 5.9mm thick and 468 grams, the Tab S5e is both lighter and thinner. The company also claims they've maximized space with the Tab S5e's massive 81.8 percent screen-to-body ratio, which on paper, is an improvement over the Tab S4's lower 79 percent ratio. It's also right on the heels of the 11-inch iPad Pro's ~82.9 percent screen-to-body ratio.

And unlike Samsung's previous attempt to make its 10.5-inch tablet more affordable, this slate doesn't skimp on the screen and not nearly as much on the processor. Samsung's Tab S5e is a 10.5-inch Super AMOLED device with a 16:10 aspect ratio and 2560 x 1600 resolution, while its octa-core Snapdragon 670 processor should provide solid mid-range performance. Samsung's also promising up to 14.5 hours of battery life. The Tab S5e is also the first tablet from the Korean tech giant to ship with Pie, the latest version of Android, along with the new Bixby 2.0 virtual assistant and information tool. Samsung is also carrying features like Dex, a desktop-style Android environment, over from other Galaxy devices, like the Note 9 and Tab S4. It allows users to interact with their device using the screen, a mouse, keyboard, or all three. Other features include AKG-tuned, quad surround sound speakers, 64GB of internal storage (microSD expandable to 512GB), with 4GB RAM (upgradable to 6GB RAM/128GB storage), and 13-megapixel back and 8-megapixel front-facing cameras. Cellular models will follow the Wi-Fi versions later this year.

According to a report from Forbes, Samsung may be exiting the 4K Blu-ray player market. "After launching its first 4K players in 2017, the company didn't add any new players to its lineup in 2018," reports CNET. "A high-end player for 2019 along the lines of its UBD-M9500 was in the works, the report says, but has now been scrapped." From the report: One of the reasons for pulling out could be that the existing players' format support has lagged behind the rest of the industry. For example, instead of supporting Dolby Vision, Samsung created its own version of HDR10, HDR10+, which was designed for use in streaming and physical media. Competitor Oppo was the first company to support both HDR10 and Dolby Vision but announced it was ending production of its 4K Blu-ray players in April 2018. Meanwhile Sony announced the M2 player at CES 2019 with support for Dolby Vision and Panasonic recently released the high-end DP-UB9000 player in Europe and Australia.

New research from The NPD Group reveals that the smartwatch market overall is growing at an impressive rate and that the Apple Watch remains the best-selling wearable on the market. "Specifically, year-over-year smartwatch unit sales in the U.S. jumped by 61% while revenue jumped by 51%," reports BGR. "As for specific revenue figures, the report relays that smartwatch revenue from November of 2017 through November of 2018 checked in at $5 billion. One particularly interesting data point is that 88% of all smartwatch sales can be attributed to Apple, Samsung, and Fitbit." From the report: "Over the last 18 months smartwatch sales gained strong momentum, proving the naysayers, who didn't think the category could achieve mainstream acceptance, had potentially judged too soon," NPD analyst Weston Henderek said in a press release. "The ability to be truly connected via built-in LTE without the need to have a smartphone nearby proved to be a tipping point for consumers, as they now recognize the value in being able to complete a wide range of tasks on the device including receiving notifications, messaging, accessing smart home controls, and more."

Indeed, Apple executives have pointed to the inclusion of LTE connectivity on the Apple Watch Series 3 as a huge selling point. Notably, Apple Watch sales during the 2017 holiday quarter were record-breaking. More recently, Tim Cook said that revenue from Apple wearables line jumped by 50% "thanks to strong sales of both Apple Watch and AirPods."

An anonymous reader quotes a report from Motherboard: Allstate, one of the largest insurance companies in the United States, just made a curious purchase. Through its subsidiary SquareTrade, the insurance giant bought iCracked, one of the largest independent smartphone repair companies in the country. The acquisition means that Allstate has become one of the most powerful proponents of right to repair legislation in the United States. According to Gay Gordon-Byrne, executive director of Repair.org, which is pushing for the legislation, the company has already loaned a lobbyist to the effort in New Hampshire.

This is potentially big news for the right to repair movement, which is trying to get laws passed in 15 states this year that would make it easier for independent repair professionals to get repair tools and parts for consumer electronics. Thus far, it's been largely a grassroots effort from organizations like Repair.org and iFixit. Companies such as Apple, John Deere, Facebook, Microsoft, and trade organizations that represent huge tech companies have used their considerable political power to lobby against these bills. But Allstate's purchase of iCracked is a potential gamechanger. iCracked is a giant chain that does a lot of third party repairs. A change in the laws would benefit it, and now Allstate, as much as the average consumer. "iCracked has been a major supporter of right to repair, and we really appreciate their valuable contribution to the fight for freedom," Kyle Wiens, CEO of iFixit, told Motherboard in an email. "I'm optimistic that this partnership will elevate the visibility of the work that we're doing together."

"SquareTrade continues to work with manufacturers as well as the independent repair community," Jason Siciliano, VP and Global Creative Director of SquareTrade told me in an email. "As this issue evolves, we will maintain good relationships and continue to listen to the key players on all sides of the debate and will work towards sensible solutions whether they are led by the industry or regulators."

LG's next upcoming flagship smartphone is the LG G8, which is expected to debut at Mobile World Congress at the end of the month. While much of the phone is similar to last year's model, LG yesterday announced some news on the phone's audio capabilities. "The phone uses the same 'Crystal Sound OLED' branding that LG has used on some of its TVs before; this means that the entire display will vibrate to work as a speaker, which was previously rumored," reports The Verge. "The news also confirms that the G8 will be the first flagship G-series phone not to use an LCD." From the report: The G8 still has a bottom-facing speaker for louder use cases like speakerphone calls, and LG says this can be paired with the top part of the screen for 2-channel stereo sound. Elsewhere, the signature quad DAC from LG's recent flagship phones returns -- which means there'll be a headphone jack -- as does the "Boombox Speaker" functionality that produces surprisingly bassy sound when the phone is placed on a table. LG has already confirmed that the G8 will have a front-facing 3D camera with a time-of-flight sensor, while rumors suggest there could be an optional second screen accessory.

Zorro shares a report from The Register: Older satnavs and such devices won't be able to use America's Global Positioning System properly after April 6 unless they've been suitably updated or designed to handle a looming epoch rollover. GPS signals from satellites include a timestamp, needed in part to calculate one's location, that stores the week number using ten binary bits. That means the week number can have 210 or 1,024 integer values, counting from zero to 1,023 in this case. Every 1,024 weeks, or roughly every 20 years, the counter rolls over from 1,023 to zero. The first Saturday in April will mark the end of the 1,024th week, after which the counter will spill over from 1,023 to zero. The last time the week number overflowed like this was in 1999, nearly two decades on from the first epoch in January 1980. You can see where this is going. If devices in use today are not designed or patched to handle this latest rollover, they will revert to an earlier year after that 1,024th week in April, causing attempts to calculate position to potentially fail. System and navigation data could even be corrupted, we're warned. U.S. Homeland Security explained the issue in a write-up this week. GPS.gov also notes that the new CNAV and MNAV message formats will use a 13-bit week number, so this issue shouldn't happen again anytime soon. The site recommend users consult the manufacturer of their equipment to make sure they have the proper updates in place.

For those hoping the next iPhone would ditch the Lightning port in favor of the more versatile USB-C port, you'll surely be disappointed by the latest rumor. "Japanese site Macotakara says that not only will the 2019 iPhone use Lightning, Apple will also continue to bundle the same 5W charger and USB-A to Lightning cable in the box," reports 9to5Mac. "This is seen as a cost saving measure. It seems that customers wanting faster iPhone charge times will still have to buy accessories, like the 12W iPad charger." From the report: The site explains that Lightning port is not going anywhere and Apple is resistant to changing the included accessories to maintain production costs. Apple can benefit from huge economies of scale by selling the same accessories for many generation. As such, Apple apparently will keep bundling Lightning EarPods, Lightning to USB-A cable, and the 5W USB power adaptor, with the 2019 iPhone lineup. This is disappointing as Apple began shipping an 18W USB-C charger with its iPad Pro line last fall, and many expected that accessory to become an iPhone standard too. Even if the iPhone keeps the Lightning port, Lightning can support fast-charging over the USB Type-C protocol. It's not clear if the cost savings of this decision would be passed on to consumers with lower cost 2019 iPhone pricing.

"Microsoft is expected to announce the next generation HoloLens headset at an already announced event on February 24, and the company's doing a bit more to stoke the flames," reports TechCrunch. One of the key people behind the original HoloLens, Alex Kipman, tweeted a video showing "vague forms of chips and cables [that] take shape out of melted ice, rocks and air," reports TechCrunch. From the report: The original headset was ahead of the mixed reality wave, but now that AR is starting to catch on all over the industry, the timing could be right for a big second-generation launch. Reports have suggested a Qualcomm 850 chip and new Project Kinect Sensors. The headset is also said to be cheaper and smaller than its developer-focused predecessor, which could put Microsoft in prime position to push augmented reality forward.

Motherboard's Joseph Cox and Jason Koebler report of the underground industry where thieves, coders, and hackers work to remove a user's iCloud account from a phone so that they can then be resold. They reportedly are able to do this by phishing the phone's original owners, or scam employees at Apple Stores, which have the ability to override iCloud locks. The other method (that is very labor intensive and rare) involves removing the iPhone's CPU from the Logic Board and reprogramming it to create what is essentially a "new" device. It is generally done in Chinese refurbishing labs and involves stealing a "clean" phone identification number called an IMEI. Here's an excerpt from their report: Making matters more complicated is the fact that not all iCloud-locked phones are stolen devices -- some of them are phones that are returned to telecom companies as part of phone upgrade and insurance programs. The large number of legitimately obtained, iCloud-locked iPhones helps supply the independent phone repair industry with replacement parts that cannot be obtained directly from Apple. But naturally, repair companies know that a phone is worth more unlocked than it is locked, and so some of them have waded into the hacking underground to become customers of illegal iCloud unlocking companies.

In practice, "iCloud unlock" as it's often called, is a scheme that involves a complex supply chain of different scams and cybercriminals. These include using fake receipts and invoices to trick Apple into believing they're the legitimate owner of the phone, using databases that look up information on iPhones, and social engineering at Apple Stores. There are even custom phishing kits for sale online designed to steal iCloud passwords from a phone's original owner. [...] There are many listings on eBay, Craigslist, and wholesale sites for phones billed as "iCloud-locked," or "for parts" or something similar. While some of these phones are almost certainly stolen, many of them are not. According to three professionals in the independent repair and iPhone refurbishing businesses, used iPhones -- including some iCloud-locked devices -- are sold in bulk at private "carrier auctions" where companies like T-Mobile, Verizon, Sprint, AT&T, and cell phone insurance providers sell their excess inventory (often through third-party processing companies.)

David Aguila, a 19-year-old bioengineering student at the Universitat Internacional de Catulunya in Spain, has built himself a robotic prosthetic arm using Lego pieces. David was born with Poland syndrome that affects his right peck and right arm. From a report: Once his favorite toys, the plastic bricks became the building material for Mr Aguilar's first, still very rudimentary, artificial arm at the age of nine, and each new version had more movement than the one before. He uses the artificial arm only occasionally and is self-sufficient without it, with all the versions on display in his room in the university residence on the outskirts of Barcelona. In November 2017 Mr Aguilar, who uses Lego pieces provided by a friend, proudly displayed a fully functional red and yellow robotic arm, built when he was 18, bending it in the elbow joint and flexing the grabber.

The latest models are marked MK followed by the number -- a tribute to comic book superhero Iron Man and his MK armor suits. The MK II was a predominantly blue model built from a Lego plane set, including a motor, while MK III was created from a set for a piece of mining equipment. After graduating from university, he wants to create affordable prosthetic solutions for people who need them.
