Antitrust officials at the U.S. Justice Department said they have "grave concerns" about plans by T-Mobile US to shut down the wireless network used by millions of Boost Mobile customers. From a report: The department's worries were disclosed Monday in a regulatory filing by Dish Network, which bought Boost as part of an antitrust settlement approved by the Justice Department that cleared the way for T-Mobile's takeover of Sprint last year. T-Mobile operates the 3G network known as CDMA that's used by Boost.

"The Division is left with grave concerns about the potential for a nationwide CDMA shutdown to leave a substantial proportion of Boost's customers without service," the acting head of the department's antitrust division, Richard Powers, wrote to Dish and T-Mobile in a July 9 letter. The dispute over the network, which T-Mobile plans to decommission on Jan. 1, is threatening the elaborate antitrust deal brokered by the Trump administration's Justice Department, which allowed T-Mobile to buy Sprint even though the deal consolidated the mobile phone market to three national players. The Justice Department had long said four players were needed to ensure the market is competitive.

"The moment you network IoT and hand over control to third parties, you may also give individuals the keys to a digital kingdom — and the ability to cause mischief, or worse," writes ZDNet.

For example, at a hotel where guests control the devices in their room with an iPod Touch... Speaking at Black Hat USA, Las Vegas, security consultant Kya Supa from LEXFO explained how a chain of security weaknesses were combined and exploited to gain control of rooms at a capsule hotel, a budget-friendly type of hotel offering extremely small — and, therefore, cozy — spaces to guests, who are stacked side-by-side... A neighbor, "Bob," kept waking Supa up by making loud phone calls in the early hours of the morning. While Bob had agreed to keep it down, he did not keep his promise — and the researcher set to work since he needed his sleep, especially during his vacation. The first thing Supa did was to explore his room, finding an emergency light installed for safety reasons; a Nasnos automaton center for use in controlling products in case the iPod Touch was lost; an electric motor used to manage the incline of the capsule's bed; and a Nasnos router, hidden in the wall.

If you connected to the router via a smartphone, it was then possible to control other devices on the network, and this was the setup the hotel chose to use... Supa found that two networks were connected — the hotel Wi-Fi and the router. To retrieve the router key, Supa targeted WEP, a protocol that has been known to be weak for years. Access points, each being one of the bedrooms, were found. Supa inspected the traffic and found weak credentials in place — "123" — and you can guess the rest...

By using an Android smartphone, the iPod Touch, and a laptop, the researcher created a Man-in-The-Middle (MiTM) architecture and inspected the network traffic. No encryption was found and he created a simple program to tamper with these connections, allowing the researcher to seize control of his bedroom through his laptop... Now that he could "control every bedroom," and Bob was still there, Supa then tampered with the lights of different bedrooms until he found the right one. He created a script that, every two hours, would change the bed into a sofa and turn the lights on and off. The script was launched at midnight. We can probably assume Bob did not enjoy his stay.

"I hope he will be more respectful in the future," Supa commented.

The Federal Communications Commission released a new set of maps Friday showing mobile service coverage and availability as reported by the major wireless providers. From a report: Billions of dollars are about to be spent on boosting broadband access for underserved Americans. The better the data that directs that spending is, the more effective the dollars will be.

The FCC says these new maps represent a step towards complying with a 2020 law that mandated better public reporting of broadband and wireless service information. The maps use a new data specification that will "improve the uniformity and consistency of broadband availability data," according to an FCC release.

Verizon Communications is enlisting artificial intelligence models to help place thousands of 5G wireless transmitters for optimal performance. From a report: Later this year, the company will begin a multibillion-dollar rollout of midband spectrum, which expands coverage of its existing ultra wideband 5G wireless service. Maximizing coverage with the least number of transmitters is a priority, said Shankar Arumugavelu, senior vice president and global chief information officer of Verizon. "When we build out these networks, these are very capital-intensive," he said. "We have to make sure that we are being very judicious in terms of how we are investing our capital."

The models, designed by in-house data scientists and other employees, factor in a number of variables that can alter the strength of 5G signals, like buildings, bridges, terrain, the position of the transmitter, as well as other transmitters nearby. Verizon, along with rivals AT&T and T-Mobile, is racing to build out nationwide 5G service, a yearslong effort slowed by the lack of available airwaves for fast transmission and long signal ranges, and by the deployment of new network equipment, analysts have said.

An anonymous reader quotes The Record: A Chinese cyber-espionage group known as APT31 (or Zirconium) has been seen hijacking home routers to form a proxy mesh around its server infrastructure in order to relay and disguise the origins of their attacks.

In a security alert, the French National Cybersecurity Agency, also known as ANSSI (Agence Nationale de la Sécurité des Systèmes d'Information), published a list of 161 IP addresses that have been hijacked by APT31 in recent attacks against French organizations. French officials said that APT31's proxy botnet was used to perform both reconnaissance operations against their targets, but also to carry out the attacks themselves. The attacks started at the beginning of 2021 and are still ongoing...

The Record understands that APT31 used proxy meshes made of home routers as a way to scan the internet and then launch and disguise its attacks against Exchange email servers earlier this year; however, the technique was also used for other operations as well.

Amazon's Kindle e-readers with built-in 3G will begin to lose the ability to connect to the internet on their own in the US in December, according to an email sent to customers on Wednesday. The Verge reports: The change is due to mobile carriers transitioning from older 2G and 3G networking technology to newer 4G and 5G networks. For older Kindles without Wi-Fi, this change could mean not connecting to the internet at all. As Good e-Reader first noted in June, newer Kindle devices with 4G support should be fine, but for older devices that shipped with support for 3G and Wi-Fi like the Kindle Keyboard (3rd generation), Kindle Touch (4th generation), Kindle Paperwhite (4th, 5th, 6th, and 7th generation), Kindle Voyage (7th generation), and Kindle Oasis (8th generation), users will be stuck with Wi-Fi only. In its email announcement, Amazon stresses that you can still enjoy the content you already own and have downloaded on these devices, you just won't be able to download new books from the Kindle Store unless you're doing it over Wi-Fi.

Things get more complicated for Amazon's older Kindles, like the Kindle (1st and 2nd generation), and the Kindle DX (2nd generation). Since those devices relied solely on 2G or 3G internet connectivity, once the networks are shut down, the only way to get new content onto your device will be through an old-fashioned micro-USB cable. For customers affected by the shutdown, Amazon is offering a modest promotional credit (NEWKINDLE50) through August 15th for $50 towards a new Kindle Paperwhite or Kindle Oasis, along with $15 in-store credit for ebooks. While arguably the company could do more to help affected customers (perhaps by replacing older devices entirely) this issue is largely out of Amazon's hands.

First Major League Baseball experimented with automated umpiring of balls and strikes in the minor leagues.

Now the Verge reports they're trying a time-saving tactic that might also make it harder to cheat: Baseball has a sign stealing problem — or at least, a technological one, seeing how reading another team's pitches is technically legal, but using Apple Watches or telephoto cameras and then suspiciously banging on trash cans is very much not. But soon the MLB may try fighting fire with fire: on August 3rd, it plans to begin testing an encrypted wireless communication device that replaces the traditional flash of fingers with button taps, according to ESPN.

The device, from a startup called PitchCom, will be tested in the Low-A West minor league first. As you'd expect from something that's relaying extremely basic signals, it's not a particularly complicated piece of kit: one wristband transmitter for the catcher with nine buttons to signal "desired pitch and location," which sends an encrypted audio signal to receivers that can squeeze into a pitcher's cap and a catcher's helmet.

The receivers use bone-conduction technology, so they don't necessarily need to be up against an ear, and might theoretically be harder to eavesdrop on. (Bone conduction stimulates bones in your head instead of emitting audible sound.)
"MLB hopes the devices will cut down on time spent by pitchers stepping off the rubber and changing signals," reports the Associated Press, noting another interesting new rule. "A team may continue to use the system if the opposing club's device malfunctions."

But don't worry about that, reports ESPN: Hacking the system, the company says, is virtually impossible. PitchCom uses an industrial grade encryption algorithm and transmits minimal data digitally, making it mathematically impossible for someone to decrypt intercepted transmissions, according to the company.

An anonymous reader quotes a report from Ars Technica: Dish Network has agreed to pay AT&T at least $5 billion over 10 years for network access amid a feud between Dish and T-Mobile. Dish is in the early stages of building a 5G network and in the meantime is serving customers as a reseller using network capacity that it purchases from T-Mobile. But Dish and T-Mobile are fighting over T-Mobile's plan to shut down its 3G CDMA network earlier than it originally intended, with Dish accusing T-Mobile of anticompetitive behavior. Against that backdrop, Dish today announced "the signing of a transformative, long-term strategic Network Services Agreement with AT&T, making AT&T the primary network services partner for Dish MVNO [mobile virtual network operator] customers."

The AT&T network capacity will serve customers on Dish's "retail wireless brands, including Boost Mobile, Ting Mobile, and Republic Wireless," Dish said. Dish also said the agreement will accelerate its "expansion of retail wireless distribution to rural markets where Dish provides satellite TV services" and that AT&T will provide transport and roaming services to support Dish's future 5G network. Dish revealed the $5 billion price in a Securities and Exchange Commission filing that also notes that the roaming and transport services from AT&T will not be limited to areas where Dish doesn't build 5G infrastructure. The deal "provides Dish's retail wireless customers with voice and data roaming services throughout the US on the AT&T network and access to AT&T's network, even within the markets where Dish is deploying its own 5G network," Dish told the SEC. Today's deal between AT&T and Dish is nonexclusive, so Dish can use both T-Mobile and AT&T capacity to serve customers. But Dish's statement that AT&T will become the "primary" network provider for Dish MVNO customers shows that Dish is trying to minimize the use of T-Mobile's network. Dish's MVNO deal with T-Mobile lasts until 2027. As part of the T-Mobile/Sprint merger-and-divestment proceedings, Dish committed to the government that it would build a 5G network serving 70 percent of Americans by June 2023.

The New York Times reports on "an intense policy struggle" in America's national and state governments:

-On one side, large electric utilities and President Biden want to build thousands of miles of power lines to move electricity created by distant wind turbines and solar farms to cities and suburbs.

- On the other, some environmental organizations and community groups are pushing for greater investment in rooftop solar panels, batteries and local wind turbines.

And the result "could lock in an energy system that lasts for decades." At issue is how quickly the country can move to cleaner energy and how much electricity rates will increase... The option supported by Mr. Biden and some large energy companies would replace coal and natural gas power plants with large wind and solar farms hundreds of miles from cities, requiring lots of new power lines. Such integration would strengthen the control that the utility industry and Wall Street have over the grid. "You've got to have a big national plan to make sure the power gets from where it is generated to where the need is," Energy Secretary Jennifer Granholm said in an interview.

But many of Mr. Biden's liberal allies argue that solar panels, batteries and other local energy sources should be emphasized because they would be more resilient and could be built more quickly... In all probability, there will be a mix of solutions that include more transmission lines and rooftop solar panels. What combination emerges will depend on deals made in Congress but also skirmishes playing out across the country...

As millions of California homes went dark during a heat wave last summer, help came from an unusual source: batteries installed at homes, businesses and municipal buildings. Those batteries kicked in up to 6 percent of the state grid's power supply during the crisis, helping to make up for idled natural gas and nuclear power plants. Rooftop solar panels generated an additional 4 percent of the state's electricity... California showed that homes and businesses don't have to be passive consumers. They can become mini power plants, potentially earning as much from supplying energy as they pay for electricity they draw from the grid. Home and business batteries, which can be as small as a large television and as big as a computer server room, are charged from the grid or rooftop solar panels...

Regulators generally allow utilities to charge customers the cost of investments plus a profit margin, typically about 10.5 percent, giving companies an incentive to build power plants and lines... A 2019 report by the National Renewable Energy Laboratory, a research arm of the Energy Department, found that greater use of rooftop solar can reduce the need for new transmission lines, displace expensive power plants and save the energy that is lost when electricity is moved long distances. The study also found that rooftop systems can put pressure on utilities to improve or expand neighborhood wires and equipment.
The director of a Chicago-based environmental nonprofit tells the Times that "Solar energy plus storage is as transformative to the electric sector as wireless services were to the telecommunications sector."

In a weird twist, fossil fuel companies are now joining forces with local groups (including environmental groups) to fight the construction of new power lines.

An anonymous reader shares the findings of a new study from the University of Chicago. From a report: If service becomes slow when you're trying to send a quick email on your smartphone, you might scroll through your network options and discover how many Wi-Fi networks there are. In fact, this plethora of options is itself the problem. These networks are in competition with one another, limiting the speed at which each can operate. University of Chicago researchers have demonstrated how this increased network competition could negatively impact internet service for everyday users.

When a cellular provider, such as T-Mobile or AT&T, licenses a spectrum band from the FCC, they reserve its exclusive use. As a result, networks operating on licensed bands experience little interference. This allows providers to establish fast and reliable service, but it comes at a cost. To improve bandwidth [to accommodate] more users] without breaking the bank, these providers have begun to also use the unlicensed spectrum via cellular networks using a mode called licensed assisted access (LAA), which operates on the same bands used for Wi-Fi. [The researchers] set out to examine how this shared use of the unlicensed spectrum, called coexistence, impacted both Wi-Fi and cellular users.

"We actually found an LAA station located on the UChicago campus, on a pole in front of the bookstore, and in this outside space campus Wi-Fi is also in use," [Monisha Ghosh, associate member in the Department of Computer Science at the University of Chicago and research professor in the Pritzker School of Molecular Engineering] said. "That provided an experimental platform in our backyard, so we started taking measurements." [...] By accessing multiple networks simultaneously, the group found that competition decreased performance -- reducing the amount of data transmitted, the speed of transmission, and the signal quality. This competition was particularly detrimental to Wi-Fi. When LAA was also in active use, data transmitted by Wi-Fi users decreased up to 97%. Conversely, LAA data only exhibited a 35% decrease when Wi-FI was also in use. Ghosh explained that the incompatibility between Wi-Fi and LAA owes in part to the different protocols each employs to deal with heavy internet traffic. The researchers presented their findings in a paper via arXiv.

A wireless pacemaker that can dissolve in the body has been created for patients who need only temporary help to regulate their heartbeat. The Guardian reports: While pacemakers can already be used for temporary periods, experts say there are problems, including that leads placed through the skin can pose an infection risk. The external power supply and control system can become accidentally dislodged, and heart tissue can be damaged when the device is removed. Now researchers say they have developed a battery-free pacemaker that can be implanted directly on to the surface of the heart and absorbed by the body when no longer needed. The device -- which Rogers said would cost about $100 -- is free of leads and can be controlled and programmed from outside the body.

Writing in the journal Nature Biotechnology, Rogers and colleagues report how they made the device -- which is thin, flexible and weighs less than half a gram -- from materials including magnesium, tungsten, silicon and a polymer known as PLGA, all of which are compatible with the body but which undergo chemical reactions that allow them to dissolve and be absorbed over time. The device, which resembles a tiny tennis racket in shape, is powered by wireless technology in which radio frequency power from an external device is sent to a receiver within the pacemaker where it is converted into an electrical current that is used to regulate the heart. Rogers said similar technology was used in applications such as wireless charging of smartphones and electric toothbrushes.

An anonymous reader quotes a report from 9to5Google: SMS is widely regarded as an insecure form of two-factor authentication, and another example of this has just emerged. A carrier looks to be injecting ads into the Google verification code used to sign in to services like Gmail. Action Launcher developer Chris Lacy today tweeted how his Google verification code -- which starts with "G-" -- featured an "SMS AD." The advertisement -- for a VPN -- includes a quick message and short URL. For those that immediately suspect this is just a phishing attempt, the verification code is legitimate and was requested by Lacy to successfully verify a login attempt. Google Messages even flagged the link/message as spam. As such, Googlers responding to the thread suspect this is an occurrence of a carrier appending an ad -- note the extra spaces -- into a real text message. It's very unlikely that Google's security teams would allow advertising into a very crucial part of the login process where end user trust is paramount.

Google issued the following statement to us today: "These are not our ads and we are currently working with the wireless carrier to understand why this happened." Google confirms that the "SMS AD" did not originate from its own advertising network. Meanwhile, it's working with the wireless carrier in question to find out what occurred. Lacy has decided "not to state the carrier for privacy reasons," and Google did not share that information either.

An anonymous reader quotes a report from The Verge: United Airlines is adding a long-awaited feature to the in-flight entertainment seatback screens of its new Boeing 737 Max 8 jets -- support for Bluetooth headphones. The company is making the upgrade as part of "United Next," a new plan to expand and modernize its fleet with what it says are larger, fuel-efficient jets and a more comfortable in-flight experience. Adding seatback screens made a huge difference in how tolerable flying is, but it's been held up by lagging audio support that The Verge has even written a guide to getting around. And this isn't a problem unique to United. Other airlines like Delta or JetBlue have been offering seatback screens for years, but have also saddled flyers with analog audio. United just might be one of the first airlines to start the next wave of inflight entertainment improvements (hopefully).

However, there's room for things to go a bit sideways. As part of its upgrades, United's new 737 Max 8 jets offer 10 or 13-inch inflight entertainment screens on the backs of all seats, which might mean a lot of people trying to connect to Bluetooth at once. That could cause interference, and might also make the process of connecting your headphones more of a chore if you're having to hunt through multiple devices trying to pair in the same menu. United currently only offers Bluetooth on its Max 8 jets which it says should start flying this summer. The company didn't share how it plans to address issues with Bluetooth, but said it's still "studying the technology."

London Underground passengers will be able to get mobile coverage across the rail network by the end of 2024, it has been announced. MacRumors reports: In a press release, Transport for London (TfL) said the capital's Oxford Circus, Tottenham Court Road and Bank stations would be among the first fully connected stations by the end of the year, followed by Tottenham Court Road, Euston, and Camden Town by the end of 2022. Mobile reception was introduced on the eastern half of the Jubilee line in March last year. TfL says the additional infrastructure will support 5G as well as 4G, but that it will be the responsibility of mobile operators to offer support for the fastest network speeds.

TfL is partnering with BAI Communications (BAI), a global provider of 4G and 5G connected infrastructure, to plug so-called coverage "not-spots" in the underground network. The over 1,242 miles of fibre cabling installed in London Underground tunnels will also benefit above-ground coverage for buildings and other infrastructure by allowing more mobile transmitters to be installed.

The BBC reports: China's Zhurong rover has sent back a batch of new images from Mars — including a "selfie". The robot, which landed in May, positioned a wireless camera on the ground and then rolled back a short distance to take the snap. To Zhurong's right is the rocket-powered platform that brought the six-wheeled vehicle to a soft touchdown. Both display prominent Chinese flags...

It weighs some 240kg. A tall mast carries cameras to take pictures and aid navigation; five additional instruments will investigate the mineralogy of local rocks and the general nature of the environment, including the weather. Like the current American rovers (Curiosity and Perseverance), Zhurong has a laser tool to zap rocks to assess their chemistry. It also has a radar to look for sub-surface water-ice - a capability it shares with Perseverance.
Slashdot reader InfiniteZero writes that the mission's "full resolution images including a 360 panoramic view of the landing site, can be found at the official CNSA website."

The three major carriers in the U.S. have now agreed to start providing vertical location data for 911 calls, which will help first responders quickly locate 911 callers in multi-story buildings. XDA Developers reports: The FCC wrote in its announcement, "FCC Acting Chairwoman Jessica Rosenworcel today announced breakthrough agreements with America's three largest mobile phone providers to start delivering vertical location information in connection with 911 calls nationwide in the coming days. This information will help first responders quickly locate 911 callers in multi-story buildings, which will reduce response times and ultimately save lives."

The FCC first announced in 2015 that carriers would be required to start sharing vertical location data. The original deadline was June 2nd, 2021, but AT&T, T-Mobile, and Verizon wanted an 18-month extension (allegedly due to issues testing the functionality during the COVID-19 pandemic). With the deadline rapidly approaching, the FCC began an investigation in April to find out what was taking carriers so long. All three major carriers have now agreed to start providing vertical location data to 911 call centers within the next seven days, and each company will pay a $100,000 settlement. The agreement also increases the scope of the vertical location data; instead of the data only being provided in select areas, vertical location information will be provided by carriers across the entire United States. However, it will likely take longer than a week for the vertical data to be used in most 9-1-1 call centers, as the change will require updated software and (possibly) additional training for emergency dispatchers.

An anonymous reader quotes a report from Bloomberg: Apple is working on a new iPad Pro with wireless charging and the first iPad mini redesign in six years, seeking to continue momentum for a category that saw rejuvenated sales during the pandemic. The Cupertino, California-based company is planning to release the new iPad Pro in 2022 and the iPad mini later this year [...]. The main design change in testing for the iPad Pro is a switch to a glass back from the current aluminum enclosure. The updated iPad mini is planned to have narrower screen borders while the removal of its home button has also been tested.

For the new Pro model, the switch to a glass back is being tested, in part, to enable wireless charging for the first time. Making the change in material would bring iPads closer to iPhones, which Apple has transitioned from aluminum to glass backs in recent years. Apple's development work on the new iPad Pro is still early, and the company's plans could change or be canceled before next year's launch [...]. Wireless charging replaces the usual power cable with an inductive mat, which makes it easier for users to top up their device's battery. It has grown into a common feature in smartphones but is a rarity among tablets. Apple added wireless charging to iPhones in 2017 and last year updated it with a magnet-based MagSafe system that ensured more consistent charging speeds.

The company is testing a similar MagSafe system for the iPad Pro. Wireless charging will likely be slower than directly plugging in a charger to the iPad's Thunderbolt port, which will remain as part of the next models. As part of its development of the next iPad Pro, Apple is also trying out technology called reverse wireless charging. That would allow users to charge their iPhone or other gadgets by laying them on the back of the tablet. Apple had previously been working on making this possible for the iPhone to charge AirPods and Apple Watches. In addition to the next-generation iPad Pro and iPad mini, Apple is also working on a thinner version of its entry-level iPad geared toward students. That product is planned to be released as early as the end of this year, about the same time as the new iPad mini. Apple is still reportedly working on a technology similar to its failed AirPower, a charging mat designed to simultaneously charge an iPhone, Apple Watch and AirPods. People familiar with the matter said it's also internally investigating alternative wireless charging methods that can work over greater distances than an inductive connection.

After being announced in 2017, the Atari VCS game console finally has a launch date: June 15th. HotHardware reports: However, pricing for the Atari VCS might leave many scratching their heads, especially considering that it is retro-centric and uses seriously underpowered hardware compared to modern gaming consoles from Sony and Microsoft. The base Onyx system is priced at $299, while an Onyx or Black Walnut All-in Bundle includes a wireless Classic Joystick and a wireless Modern Controller. Unfortunately, that bundle will set you back an eye-popping $399.

The Atari VCS [...] uses a rather pokey AMD Ryzen R1606G embedded APU. [...] However, Atari says that the VCS can also function as a full-fledged PC. You can even install Windows 10 or Linux on it, turning it into a versatile multimedia computer. The hardware is reportedly capable of running 4K videos and includes a built-in "Vault" containing 100 retro Atari 2600 and arcade games. That's all well and good for those with a penchant for retro gaming, but remember that we're talking about games that debuted roughly 40 years ago. That nostalgia could run a bit thin when you're talking about a device that costs $299 and up. Atari says over 11,000 of its original Indiegogo campaign backers have already received their consoles. Everyone else will have to purchase directly from Atari or a third party.

Samsung is killing the first-generation SmartThings Hub at the end of the month, kicking off phase two of its plan to shut down the SmartThings ecosystem and force users over to in-house Samsung infrastructure. "Phase one was in October, when Samsung killed the Classic SmartThings app and replaced it with a byzantine disaster of an app that it developed in house," writes Ars Technica's Ron Amadeo. "Phase three will see the shutdown of the SmartThings Groovy IDE, an excellent feature that lets members of the community develop SmartThings device handlers and complicated automation apps." From the report: The SmartThings Hub is basically a Wi-Fi access point -- but for your smart home stuff instead of your phones and laptops. Instead of Wi-Fi, SmartThings is the access point for a Zigbee and Z-Wave network, two ultra low-power mesh networks used by smart home devices. [...] The Hub connects your smart home network to the Internet, giving you access to a control app and connecting to other services like your favorite voice assistant. You might think that killing the old Hub could be a ploy to sell more hardware, but Samsung -- a hardware company -- is actually no longer interested in making SmartThings hardware. The company passed manufacturing for the latest "SmartThings Hub (v3)" to German Internet-of-things company Aeotec. The new Hub is normally $125, but Samsung is offering existing users a dirt-cheat $35 upgrade price.

For users who have to buy a new hub, migrating between hubs in the SmartThings ecosystem is a nightmare. Samsung doesn't provide any kind of migration program, so you have to unpair every single individual smart device from your old hub to pair it to the new one. This means you'll need to perform some kind of task on every light switch, bulb, outlet, and sensor, and you'll have to do the same for any other smart thing you've bought over the years. Doing this on each device is a hassle that usually involves finding the manual to look up the secret "exclusion" input, which is often some arcane Konami code. Picture holding the top button on a paddle light for seven seconds until a status light starts blinking and then opening up the SmartThings app to unpair it. Samsung is also killing the "SmartThings Link for Nvidia Shield" dongle, which let users turn Android TV devices into SmartThings Hubs.

Xiaomi's at it again: The company's new fast charging technology can get a smartphone from 0 to 100 percent battery in less than 8 minutes. From a report: The 200W wired charging tech, used on a modified Xiaomi MI 11 Pro with a 4,000mAh battery, gets the phone from 0-10% in just 44 seconds. The phone gets to 50% in 3 minutes, and it's fully charged in 7:57 minutes. In a YouTube video, Xiaomi also showcased its 120W wireless charging tech, which gets a smartphone with a 4,000mAh battery from 0 to 100 percent battery in 15 minutes.
