SPC was the mobile brand for seniors. Now it has a system that learns when your grandfather stops behaving as usual

by

SPC has been digesting for a year the change that Teresa Acha-Orbea, its general director, described us at MWC 2025: going from a telephone manufacturer for seniors to a comprehensive technological services company. Again in Barcelona and again at the MWC, the company from Alava has presented the first product that materializes this transformation. It’s called Zeus Halo, and it’s a predictive telecare platform built around a hub domestic 5G with a 12-inch screen, four microphones and IoT connectivity to integrate sensors, activity bracelets and other home devices. It appears on the right in the image that heads these lines. The proposal is based on a demographic premise that defines our country today: Spain ages. According to INE projections, In 2030 almost a third of the population will be over 60 years oldand a growing portion of that group lives alone. Current telecare systems work reactively, waiting for something to happen before acting. Zeus Halo points in the opposite direction: the system learns the user’s behavior patterns. What time do you get up, how many times do you go to the bathroom, when do you leave the house… When these habits change abruptly, the device generates a preventive alert that reaches the smartphone of family members or caregivers, or directly to third-party telecare platforms. “If this person usually goes to the bathroom several times a day and suddenly they are only in the living room, something is happening,” explains Acha-Orbea in the stand of SPC in the Spanish Pavilion. It can also detect falls through the activity bracelet, monitor heart rate or temperature, and send alerts if the person leaves and does not return. The hardware does not require a router, or even that there is a WiFi network in the house, because the hub It carries a 5G SIM and covers all the sensors in the home, which eliminates a common installation barrier for this user profile. Compatible sensors include presence, door opening and smoke detectors, in addition to wearables. Cameras are technically possible, but SPC has decided not to incorporate them by default: “We all want to maintain our privacy, at least visually,” says Acha-Orbea. The second leg of Zeus Halo is the conversational agent. The platform includes a voice assistant that learns the user’s tastes and interests and maintains conversations adapted to them, with reminders for medication, medical appointments or birthdays that are delivered as voice calls instead of text messages, because “SMS are not usually read”, something that was already explained to us a year ago. The system can also organize secure video calls with family members through its own application, suggest activities inside and outside the home or connect Zeus Halo users with common interests. The unwanted loneliness of older people has been on the public agenda for years, The product will be launched before the end of the year in two modalities: ORa version for retail intended for families who want to install it in their parents’ or grandparents’ home And another institutional version for councils, municipal social services, residences, telecare and insurance companies that need to monitor their users proactively. SPC has clients such as CaixaBank or the Generalitat of Asturias in its portfolio, which gives it direct access to the type of organization it targets with the B2B version. The launch of Zeus Halo is accompanied by a brand repositioning. SPC launches logo, website (now in onspc.com) and a new definition of itself: “technology consultancy” that combines manufacturing, systems integration and consulting under the umbrella ‘human by design. The company, founded at the end of the eighties taking advantage of the liberalization of telecommunications, which for decades lived by selling landlines and mobile phones adapted for the elderly, today has 78 employees and headquarters in Vitoria, Lisbon and Shenzhen. It sells about 400,000 units per year of basic phones for seniors and about 30,000 adapted smartphones. It is, according to its own figures, the first Spanish brand in that niche with 50% of the national market. The transition that Zeus Halo embodies has not come for free. SPC has had to recruit software engineers and is setting up its own engineering in China to work directly with software manufacturers. chipsets. He 2G blackoutwhich forced the company to redesign its catalog a few years ago, turned out to be the lever that turned “dumb” devices into platforms capable of exchanging data. Zeus Halo is the next step in that same logic: a little hardware gadget that becomes the connected brain of the home.

Why it is not advisable to connect the charger to the mobile phone before connecting it to the power

by

Putting your phone on charge is a gesture that we do practically every day and it is something that is apparently very simple. Well, it turns out that we are doing it wrong. There is a key detail that many of us overlook and that can have negative consequences for both the cable and the mobile port. There are many recommendations for take care of battery healthsuch as avoiding downloading it to the maximum or charging it to 100%, but there is another factor that is not usually taken into account and that is the order in which we connect the cable. The order of the factors does alter the product And if not Tell my partner Álex Alcoleathe owner of the Lightning cable in the photo below these lines. The fact that the pins have turned black is not a dirt problem, but rather an order problem. Álex used to connect the cable to the cell phone and then to the power, which generates a brief voltage spike that goes directly to the connector. For once nothing happens, but if we do it continuously the result is a fried cable. This is how our colleague Alejandro Alcolea’s Lightning cable looked after several months It is a common phenomenon in any type of plug: you plug it in and a surge occurs. If the cable is already connected to the phone when this happens, a small electrical arc may be created where the pins make contact. This little sparkcan cause the cable pins to become damaged and, over time, the charge begins to fail or we have to move the cable to make contact. If you are wondering if there is a possibility of frying your cell phone with this habit, don’t panic. Smartphones have internal protections to prevent them from being damaged if there is a voltage spike and we are also talking about a very brief spike. The recommended order to charge your mobile Preventing that small spark from damaging the connectors is as simple as reversing the order, that is, connecting the charger to the socket and then connecting it to our mobile phone. In this way, the voltage peak remains contained in the charger and it does not occur when we connect the mobile. Manufacturers like Huawei and Samsung They recommend following this order to avoid possible damage: Plug the charger into the power outlet. Connect the cable to the charger (if separate). Finally, connect the cable to the mobile. What to do if your cell phone doesn’t charge If your cable or the charging port on your phone is starting to fail, the charging order could be a possible reason. To find out, check if the cable pins are blackened like those in the photo at the beginning, although if it is a USB-C it is more difficult to see since they are inside. The most common thing is that dirt has accumulated in the charging port and this does not let the cable connect well. If this is the case, you can clean it using a wooden toothpick, always being very careful not to damage the charging port. It may also be that your mobile does not charge because moisture has entered the port. In this case, try to remove the liquid by tapping it against your hand and leave the phone in a place where there is air flow, never insert anything to remove the liquid as you can make it enter even more. If the problem is not with the cable or the port, it is possible that it is with the battery, so you will have to go through technical service.

a photographic show that aspires to become the best mobile phone of 2026

by

Xiaomi has a new workhorse for the highest range. It is the Xiaomi 17 Ultra, one of the most ambitious phones on the market and a clear candidate for best mobile of 2026. On paper, it has everything to compete head-to-head with anyone that comes before it: a camera system that, at least in hardware, sets new benchmarks in the sector, a generous battery and Qualcomm’s most powerful processor. We review the characteristics of the Xiaomi 17 Ultra. Xiaomi 17 Ultra technical sheet xiaomi 17 ultra dimensions and weight 162.9mm x 77.6mm x 8.29mm 218g screen 6.9 inches Xiaomi HyperRGB Resolution 2608 x 1200 LTPO adaptive refresh 1-120 Hz 3,500 nits peak brightness HDR10+, Dolby Vision processor Qualcomm Snapdragon 8 Elite Gen 5 Storage 12 + 256GB 12 + 512 GB 16GB + 1TB rear cameras 50 MP, f/1.67 OIS, 23mm equivalent 200 MP, variable aperture f/2.39-f2.96, OIS, 75-100mm equivalent 50 MP, f/2.2 ultra wide angle front camera 50MP, f/2.2 battery 6,000mAh 90W fast charging 50W fast wireless charging operating system Android 16 based on One UI 8.5 connectivity 5G Wi-Fi 7Bluetooth 6GPSNFCUWBUSB type C price From 1,449 euros The lightest Ultra Regarding the design, the Xiaomi 17 Ultra It is the lightest and thinnest Ultra to date. Xiaomi has left the curvature behind (thanks, Xiaomi) to create a flatter and straighter device, weighing below 220 grams. Not bad considering that we are looking at a phone with a good-sized battery and that measures more than 16 centimeters high. Xiaomi has abandoned the curves and its new Ultra looks better than ever. It’s thinner, lighter, and even more refined It is manufactured in aluminum alloy for its sides, and fiberglass in its rear part. In the Stellar Green finish, the phone is made with mineral particles, giving a very attractive shine effect. The device’s screen is 6.9 inches, flat, with OLED technology and a peak brightness of 3,500 nits. The company has worked especially to make it a panel that is not harmful to the eyes, and has TÜV certifications for blue light emission and flickering. Chicha, lots of chicha About the hardware it is exactly what you expect: Qualcomm Snapdragon 8 Elite Gen 5configurations of up to 16 GB of RAM + 1 TB, LPDDR5X and UFS 4.1 memories, and a 6,000mAh battery with 90W fast charging and 50W wireless fast charging. Perhaps a little more fast charging could be expected given the size of the battery and knowing that some cheaper Xiaomi phones have been using 120W systems for years, but they are not figures to complain about. If you are wondering about the composition of the battery, we are talking about a silicon content of 16%, so we are looking at the technology expected in a phone of this height. The software stars Xiaomi HyperOS 3 and is based on Android 16with an additional layer of artificial intelligence powered by both Gemini and Xiaomi under the name of Xiaomi Hyper AI. The camera, tell me about the camera The reason for this phone is the camera. Because it’s not just any camera. The main sensor repeats the size that every flagship should aspire to: one inch. The lens is signed by Leicaand the resolution is again 50 megapixels. But the magic of this phone, like any high-end phone, is in the zoom. The telephoto lens is one of the most ambitious at the moment: variable aperture, focal range from 75 to 100mm and resolution of 200 megapixels. The zoom is mechanical, allowing you to shoot at 75 and 100mm without loss of quality between focal lengths. It has a Samsung HPE sensor, one of the most current and capable at the moment. To top it off, it has a 50-megapixel ultra-wide angle, and a selfie camera with the same resolution. As usual in the Xiaomi Ultra, this year we can also bet on the photography kit. This not only allows for a better grip and adds a physical button panel to be able to photograph with a more analog experience, it also adds 2,000mAh capacity to the phone so that it can last the day even better. Versions and price of the Xiaomi 17 Ultra The Xiaomi 17 Ultra will arrive in Spain in four color options: Black, White, Starlit Green. We can buy it in two variants: Xiaomi 17 Ultra 16GB+512GB: €1,499.99 Xiaomi 17 Ultra 16GB+1TB: €1,699.99 The Photography Kit It will be available in three color options: Silver, White, Purple for a price of €99.99 in my.com and official distributors. The Photography Kit Pro will arrive in black and will be available for €199.99 on mi.com.

It turns out that to innovate in mobile phones, only one thing was needed: (very) useful little things.

by

Neither the latest Qualcomm processor, nor “agent” AI, nor a camera with 200 megapixels. What surprised us most this week with the launch of the Galaxy S26 Ultra It was his anti-gossip screen. A friendly reminder that, perhaps, innovation in technology does not involve the most technical characteristic, but rather the most useful one. A touch of attention. We have been criticizing for years (and rightly so) that mobile phones do not innovate. For some time now, attending the presentation of a new model is usually summarized in: Same mobile Best camera (sometimes not even that) More power AI functions that, with a high probability, we will never use The umpteenth improvement in hardware that has been nearing its peak for years This is why, as soon as we see one of those novelties of the “oh, I want that in my daily life“, we return to that smile from when mobile phones were devices designed to make our lives easier, and not so much to sell hardware deployments at the highest possible price. The anti-peeping screen. Yes, we already know that there are €1 screen protectors that perform a similar function, but the point is that this screen includes it from the factory, and with brutal technology. It is capable of regulating the emission of the pixels so that we are only able to see the panel from the front. This opens the door to having a native security layer on our screen and, by the way, being able to put a quality screen protector on it (protection ones are usually not). The matte screen. A couple of years ago, Samsung surprised the world with the matte screen of the Samsung Galaxy S24an anti-reflective layer that represented a before and after when viewing content. Apple tried something similar in its last generation, but couldn’t come close. Once again, a silent innovation that did not impress on the technical sheet, but in terms of utility it was outstanding. Apple’s square sensor. People take selfies, lots of selfies. And turning the phone to do them is not a drama, but if you can save it, all the better. It is just what Apple invented with its iPhone 17 and the square sensor: one that allows the mobile to record and take photos both vertically and horizontally in the same position. NXTpaper screens. Although the superiority of the physical book over the electronic reader is a debate that I do not want to open (and that I do not intend to lose), TCL has been doing something for some time that its competition does not dare to imitate: dual panelswhich can be used as an electronic reader and as a traditional panel. How does it work? These phones and tablets are modified LCD panels with a different matrix than the rest. The backlighting system, the anti-reflective layer and the microtexture of the surface itself are adjusted to emulate an electronic ink panel, and thus be much less aggressive to the eye when we are reading. 10,000mAh batteries. Quietly, smartphone batteries are undergoing their biggest revolution. The main change: betting on silicon to give us much more generous capacities. Because yes, innovating is making the phone last three days, and not one as we have been accustomed to for years.

It is Samsung’s plan to conquer AI in mobile phones

by

Samsung has just unveiled its new high-end: the new Galaxy S26 family is here and arrives with a conservative proposal but at two speeds where the Ultra model is the one that comes out the best. And it also brings more artificial intelligence than ever. Leaving aside the long list of functions that were already in Galaxy AIthose that have improved and new features such as ‘Now Nudge’ or Agentic AI, the big surprise It’s a confirmation: Perplexity lands as a full-fledged assistant alongside what already existed, Bixby from home and Gemini of Android. Full integration. Perplexity comes to compete head-to-head with the home assistant and Google assistant as long as it is integrated at the operating system level. What does this mean? That you can invoke it to use it in system apps such as Notes or Reminder, but also with some third-party applications. It is not a downloaded app: it operates on the device’s framework layer. And as such, you can invoke it via ‘Hey, Plex’ (without Aitana’s boyfriend appearing) or from the side button. This point is more than a simple detail: it is using the hardware as a distribution lever: whoever controls the hardware controls how the user accesses it. A reminder: Google paid a million to Apple to be the search engine on iOS. Context: Samsung’s pending issue. Few mobile manufacturers bet as much and as well on AI as the Korean firm. Samsung It is the brand that sells the most mobile phones within the Android ecosystem, but the assistant battle has been lost with Bixby. On the other hand, he has to integrate Gemini by contract. In short, Samsung cannot control its entire artificial intelligence layer sovereignly and that is a dangerous strategic dependency if you want to be the best. Samsung’s trump card: being a Swiss army knife. According to an internal Samsung investigationabout 80% of users already use two types of AI agents in their daily lives, so they have turned flexibility into a plus. Since Samsung knows that it cannot go to war with the best language model alone and win, it has opted to become a neutral hub, which allows it to attract advanced users who want to use the best of each house without friction. As declared Won-Joon Choi, President, COO and Head of R&D Office of Mobile eXperience Business at Samsung Electronics: “We are committed to building an integrated, open and inclusive AI ecosystem that offers users more choice, flexibility and control to perform complex tasks quickly and easily. Galaxy AI acts as an orchestrator, integrating different forms of AI into a single, natural and cohesive experience.” Why is it important. Because with this movement Samsung has changed the rules: it declares itself platformnot an assistant. It is a layer that coordinates several agents, leaving behind the “one assistant to rule them all” thing. The Korean firm thus differentiates itself from Apple’s vertical control and closed integration or Google’s tactic of prioritizing Gemini above all and even putting it in the soup. The movement is most intelligent: it thus neutralizes his weakness (Bixby) to transform it into a virtue. They deliberately decide to open up and let the user choose with whom and for what. Why Perplexity and not another. Here is an elephant in the room that should be remembered first of all: because the most mainstream AI, ChatGPT, She is already married to Apple. From here, it must be clear that Samsung has chosen the best possible strategic partner for its corporate interests at this time. And there are a few reasons: Because it offers a differentiated and complementary value proposition: it is a quality conversational chatbot that cites sources, without advertising and verifiable answers. Its presence is not a redundancy of Gemini, which can be used for productivity and the Google or Bixby ecosystem, for the device. A starting point in the most favorable negotiation: Perplexity is a startup that needs alliances for massive distribution against the power of Google and OpenAI, whose valuation exceeds half a billion dollars. This puts Samsung in a position to get better conditions. He already had a relationship with the startup, whose AI It is already present on the Korean brand’s TVswhich implies that they are not starting from scratch: their teams already know the respective APIs. Its anti-ad positioning. Samsung, which is betting heavily on privacy, has a strong argument here to offer a differential experience compared to Google. Reduce the Googledependency. With Perplexity, Samsung diversifies its partners without fanfare with Google in a move of corporate geopolitics. The Korean firm has a multi-million dollar deal of distribution with Google and with this twist, their position is more advantageous when negotiating or putting pressure on the Mountain View company: they have Perplexity in the bedroom as a third agent.

Mobile software has become so complex that Samsung has had to add an AI to explain it to you

by

There’s a feature in One UI 8.5 that says more than it seems. It’s called, in Samsung’s internal nomenclature, ‘voice settings assistant’: you ask the phone why the screen doesn’t turn off, and it explains which setting is causing it. You ask it why the volume goes down on its own, and it tells you where the setting is that controls it. In it briefing of the Galaxy S26 They mentioned it almost in passing, as a nice detail among bigger and more important news such as the 3 AIs in 1, or the spectacular screen and its privacy mode. But this also deserves some attention. For years, learning to use a cell phone was part of the deal. You scanned the menus, memorized where things were, got used to their quirks, and cursed when you changed brands and couldn’t find anything. The instruction manual disappeared many years ago because it was assumed that phones were already intuitive enough not to need it. And for a while, they have been. The problem is that phones have not stopped growing. Every generation, and I’m looking at both iOS and Android, adds settings, modes, features, and layers of customization. One UI 8.5 brings, in the AI ​​section alone, more than a dozen new functions. The Christmas tree effect: We accumulate things without getting rid of the previous ones and we end up with an unruly mammoth. The operating system of a modern mobile phone has thousands of options spread out in menus that are sometimes where you would expect and sometimes not. And when something behaves unexpectedly, finding the reason can take several minutes of searching or a simple query to Google. Or ChatGPT. Samsung has decided that the solution to this complexity is not to simplify, but add a layer to help you navigate it. The mobile phone no longer expects you to understand it: it explains how it works if you ask it. It is a pragmatic move. Manufacturers have been in a race for years to add functions that justify the annual update, and retracing that path would mean cutting features that some users do use. So the solution is not to remove, but to translate. An AI that acts as a guide within the device itself. Google already has similar functions in pure Android and the Siri that the prophets promised maybe one day it will come. What Samsung does with One UI 8.5 is go a step further: it not only takes you to the setting, but explains why that setting is affecting the behavior that misses you. It’s the difference between giving you directions and explaining the map to you. The question that remains is how far this goes. If the phone needs an AI to explain itself, The next logical step is for that AI to start making decisions for you.: not only explain why the screen does not turn off, but also turn it off when it detects that you are not using it. Some of the agentic upgrades that Samsung has presented in the S26 are already going in that direction. The cell phone that asks you what you want to do and the cell phone that deduces what you want to do are closer than they seem.

A few years ago, manufacturers fought for the most powerful mobile phone. Now they fight so they don’t go out burning

by

Not too long ago, Samsung and Apple were trying to convince us of something: the titanium It was the best material for a high-end mobile phone. As a user of both the latest Galaxy and the previous iPhone, I have to say that I agreed: we were never looking at mobile phones more resistant to shockschips and all kinds of everyday accidents. With the iPhone 17 ProApple backtracked to return to aluminum. With the Samsung Galaxy S26 Ultrathe Korean company follows the same path. What is happening? Aluminum is back, and everything indicates that it is here to stay. One of the main advantages that titanium promised over aluminum was to promise greater resistance, something that is being demonstrated the drama of the new iPhone 17 Pro and its premature wear compared to previous models. Despite this, companies are returning to aluminum. There is something that both the new Galaxy S26 Ultra and the iPhone 17 Pro Max share: they both have the largest dissipation systems ever built in their families. A titanic effort (to the point of completely redesigning the chassis in the case of the iPhone) to prevent mobile phones from burning in the hand. And there is a key point in this party: we want more and more powerful phones, but someone has to cool them down. Producing mobile phones in titanium is also more expensive, and given the current component crisiswith the RAM shot and internal memories the same wayone of the few cuts that can be made without affecting the overall phone experience is changing the material used. The question about whether we need more power or not, a few years ago, was answered with a resounding “yes.” But for some time now we are not so clear. With configurations of 12 and 16 GB of RAM, and processors that are more powerful than some desktop chips, our smartphones have been increasing power for years without determining too much. Why do we need these new limits?. AI requires RAM and not so much raw power (at least, in the use given to a phone), mobile games are already bordering on the quality of triple AAA console games, and improvements in camera come more through the redesign of algorithms and not so much through increasingly powerful IPS (image chips).

We have been blaming mobile phones for myopia for years. Now we have a much more subtle suspect: lack of light

by

It is quite a grandmother’s and mother’s phrase to hear that spending a long time in front of a screen or being very close to a book can cause us to develop a disease in the eyes like the myopia. However, science has long suspected that “close work” alone does not explain why myopia has become a global pandemic. The new. Now a revealing study has proposed a physiological mechanism that fits all the pieces of the puzzle together, placing the blame not only on what we look at, but on the amount of light that reaches the back of our eye while we do so. And the investigation is quite justified, since the data is scary. In Spain, 19% of children between 5 and 7 years old are already myopicand projections estimate that by 2050 half of the world’s population will need glasses. To stop this, we need to understand exactly the mechanism that produces myopia, and a team from New York has found the key. The famine of light. The work, recently published in the prestigious magazine Cell Reports by researchers, points to a fascinating concept in this case: the light deprivation hypothesis. Until now we knew that focusing on nearby objects is closely linked to the development of myopia. But what this study has measured with empirical precision is how the myopic eye reacts to the healthy eye during this process. What they have seen. The main finding is that myopes suffer from excessive accommodative pupillary constrictionthat is, when you look closely, the pupil becomes much smaller than normal. If we add to this that close-up work is usually done indoors where lighting rarely exceeds 500 lux, compared to 10,000 lux outdoors, the result is a lethal cocktail for the eye: the combination of dim light and a maximally contracted pupil causes the retina to “starve” due to lack of light. The short circuit. Here the question that logically must be asked is: Why does this lack of light cause the eye to grow abnormally, causing myopia? This is where the purest neuroscience comes in, since our retina processes the image through two main channels: the ON path that is activated with increases in light, and the OFF path, which reacts to shadows. In previous work from 2024, this same team had already shown that in myopic patients the ON pathways have serious deficits, since they are less sensitive and slower. Now the new hypothesis postulates a vicious circle in which, when reading or looking at a cell phone indoors, the pupil closes too much. And this is a problem, since chronic lack of light further weakens the retinal ON pathway, and this imbalance sends erroneous signals that ultimately promote elongation of the eyeball. The treatments. This proposal not only stands out for explaining the biological mechanism of myopia, but also unifies at once why the treatments that ophthalmologists They have been applying it empirically for years. One of the examples is spending time outdoors, but not because it cures, but because the sunlight is so intense that it more than compensates for having a small pupil, keeping the ON pathway stimulated and slowing the progression of myopia. Another example is the use of atropine drops in children to stop myopia thanks to the dilation of the pupil so that more light enters the retina. The same goes for multifocal lenses that are used to reduce accommodation effort, since the pupil does not need to constrict as excessively. It is not definitive. As is almost always the case in science, this work does not demonstrate a direct coincidence yet, but rather offers us an incredibly solid and plausible physiological mechanism supported by very robust data on the behavior of our pupil and neural pathways. But there is still a way to go with new long-term studies to confirm the hypothesis 100%. While we wait for those results, the practical conclusion seems clearer than ever: the problem is not just the tablet or the book. The problem is doing it in the dark, so if you are going to strain your eyes up close, make sure you turn on a good lamp and, above all, don’t forget to go out into the sun.
