The smartwatch market doesn't appear to be cooling down any time soon — if anything, it's heating up. Strategy Analytics estimates smartwatch shipments grew by a whopping 47 percent year-over-year in the second quarter of 2021, with 18.1 million of the wearables shipping this spring. Demand (at least from retailers) has returned to "pre-pandemic levels," according to the analyst firm's Steven Waltzer — it hasn't been this hot since 2018.

Strategy Analytics attributed the spike to continued demand for personal health devices. It's not clear how much the pandemic recovery fuelled demand, although it wouldn't be surprising if the renewed interest in going outside prompted extra sales.

It wasn't just the usual companies that benefited from the surge, either. Apple held on to a comfortable lead with 52 percent of the market and the most popular individual smartwatch (the Apple Watch Series 6), and Samsung saw its shipments jump 54 percent. Garmin's fitness-focused watches still jumped 25 percent, though, and "others" (including Fossil and other Wear OS backers) saw their shipments climb 55 percent. This was a strong overall market, even for smaller brands.

There are signs this spike will continue. Apple Watch Series 7 could be weeks away as we write this, and Samsung's Wear OS-packing Galaxy Watch 4 might revitalize Android smartwatch sales. Low-cost LTE smartwatches from Chinese brands like Oppo and Xiaomi might also help, according to the analysts. This momentum will eventually die down, but it's unlikely to fade in the near future.

How will GoPro improve on its Hero 9 Black action camera? By focusing on the fundamentals, apparently. WinFuture claims to have leaked GoPro Hero 10 Black images suggesting the upcoming cam will improve image quality. Most notably, it would have a GP2 processor allowing 5.3K video at up to 60 frames per second — you wouldn't have to choose between 5K and glass-smooth frame rates like you do with the Hero 9, which only manages 5K at 30FPS.

GoPro will reportedly jump to a 23-megapixel sensor (versus 20MP in the Hero 9) that allows higher-resolution photos. You might also see improved video stabilization through HyperSmooth 4.0, although it's not clear how the company will improve its "gimbal-like" anti-shake technology.

There's no mention of when GoPro might introduce the Hero 10 Black, although it launched the Hero 9 in September last year. We wouldn't be surprised if the follow-up was weeks away. It might be a well-timed release, too. Now that society is (slowly) reopening, there are more opportunities to embark on outdoor adventures — more people may be looking for action cams to document their expeditions.

Don't despair if you're having problems making calls on your iPhone 12 — there might be a free fix for it. 9to5Macreports Apple has introduced a repair program for a "very small" number of iPhone 12 and 12 Pro units with faulty earpieces that don't emit sound during calls. If your phone has this problem and was made between October 2020 and April 2021, Apple and authorized repair shops will fix the issue at no cost for up to two years after the "first retail sale."

Apple blamed the issue on a failure-prone component in the receiver. This program doesn't cover the iPhone 12 mini or 12 Pro Max, suggesting they use different receiver hardware.

This is the first repair program for the iPhone 12. We wouldn't expect more given Apple's generally solid track record with recent iPhones (a minority of iPhone 11 units had unresponsive screens). If nothing else, though, this serves as a reminder to check for programs like this before you assume a repair will prove costly.

The T-Mobile customer data breach might not have been a sophisticated data breach — in fact, it might have been relatively trivial. The hacker claiming to be responsible for the attack, John Binns, told the The Wall Street Journal in a discussion that T-Mobile's security was "awful." Binns reportedly broke through by using a readily available tool to find an exposed router, and took a week to delve through customer data stored in a data center near East Wenatchee, Washington.

Binns, who provided apparent evidence to back up his claims of involvement, said he breached T-Mobile and stole the data to create "noise" that drew attention to him. He came forward to highlight his claims he had been kidnapped in Germany and placed into a fake mental hospital. There wasn't any evidence to support that allegation.

T-Mobile declined to comment on Binns' claims in response to the Journal. It previously stated that it was "confident" it had closed the security holes used in the breach, which compromised sensitive info for more than 54 million active and former customers.

The incident is the third breach in two years, and suggests that T-Mobile is still struggling to offer security that matches its rapidly growing customer base. It only hired a new security leader earlier in 2021, for instance. If Binns' claims are accurate, though, the ease of the attack is also frightening — it only took a casual hack to put tens of millions of people at risk of fraud and other data crimes. The company may need to scramble if it's going to reassure customers that breaches will be rare going forward.

The sexual harassment lawsuit against Activision Blizzard will have more repercussions for game content. Blizzard is changingOverwatch character Jesse McCree's name now that his real-life namesake has left the company. The developer wants a name that "better represents" Overwatch ideals, according to a statement.

The company had planned a story arc for September that would have featured McCree, but is delaying that narrative until later in 2021 to reflect the name change. Players will instead get a new free-for-all map that month. Blizzard also promised that it would no longer name characters after employees, and said it would be more "thoughtful and discerning" about referencing the real world in Overwatch.

The real Jesse McCree left Blizzard earlier in August, just weeks after his name surfaced in a California lawsuit over sexual discrimination and harassment at the gaming giant. McCree was reportedly spotted in photos of BlizzCon's notorious "Cosby Suite" hotel room where Blizzard workers allegedly harassed women.

This isn't the first time Blizzard has altered content following the lawsuit. It pulled World of Warcraft's references to Alex Afrasiabi, directly accused of harassment, soon after the suit emerged. However, this might be more noticeable. McCree is one of the best-known characters in Overwatch — the name change could easily draw attention to the lawsuit and the "frat boy" culture that reportedly persisted for years.

YouTube is making good on its promise to bring picture-in-picture viewing to iOS users. TechCrunchreports that YouTube is promising PiP viewing to all iPhone and iPad users in the US, starting with volunteers using Premium. You'll have to opt into the test through the experiments website on your computer, but you're all set after that — you can watch clips in a floating window while you check your social networks or otherwise get things done.

Premium testing ends on October 31st. You might have to reinstall the YouTube app if the feature isn't available right away.

The company hasn't said when it plans to enable PiP for non-Premium subscribers. This is still a step forward, mind you. YouTube's web-only support was limited at best — this should expand the audience and put YouTube's app more on par with competing video services.

Apple thinks it might have a simple way to attract wary publishers to Apple News — give them a larger slice of app sales. TechCrunchreports that Apple has launched a News Partner Program that lowers the tech firm's cut of App Store subscriptions from 30 percent to 15 percent "from day one" if qualified publishers provide their content in the Apple News Format. Outlets previously had to wait until an app's second year on the App Store before Apple's share dropped to 15 percent.

The apps themselves have to deliver "original, professionally authored" news and, unsurprisingly, allow auto-renewing subscriptions through the App Store. If a publisher isn't located in one of Apple News' existing markets (currently the US, UK, Australia and Canada), it can still qualify for the program by providing an RSS news feed.

The move could satisfy publishers that avoided Apple's in-app subscription system, if not the App Store entirely, due to the 30 percent initial cut. You might see more publications on Apple News (if not necessarily News+) as a result. However, it's not clear if antitrust regulators will be thrilled. The program does show that Apple can be more flexible with App Store fees, but it's also an incentive for publishers to dive deeper into Apple's ecosystem.

NBA 2K21's WNBA mode was barebones, to put it charitably, but 2K and Visual Concepts intend to flesh things out for the follow-up. The developers have detailed improvements to "The W" in NBA 2K22 that address some of the core complaints. Most notably, there's a new badge-based player progression system that lets you upgrade your MyPlayer creations to match your specialties. It still doesn't appear to be as sophisticated as the MyCareer mode from 2K21, but it should be more involving.

Off-the-court advancement has received improvements, too. Instead of picking options on a card, there are three playable experiences (scrimmage games, team practices and category-specific contact workouts) to improve your badges. The contact drills will also help you form bonds with WNBA stars, according to 2K.

You'll also find upgrades to the next-gen-only online mode. You can now hook up with friends before you start matchmaking, and you'll earn season experience points whenever you play against other people.

As Polygonnoted, there are still areas where the WNBA component will be underdeveloped compared to the men's league. There aren't mentions of improved team management or options to spend your virtual currency. Like with other sports titles, it could take a while before the modes are on par. The creators are clearly aware they need to catch up, though, and 2K22 appears to be an important first step.

One of the most influential game console designers is bowing out. According to Kotaku, NES and SNES designer Lance Barr has retired from Nintendo after 38 years and eight months at the company. Although relatively few know his name, he may have played a key role in obtaining mainstream acceptance for Nintendo and reinvigorating the video game industry in the US.

Barr joined Nintendo in a part-time role in December 1982, but he made his biggest mark when he was asked to design the outside of the NES to make the Famicom more palatable for American audiences. As requested, he made it look like it belonged next to a stereo system (complete with a VHS-style cartridge loader) compared to the "soft" Japanese model. The console's final look was rushed, though — while the prototype NES at CES was a sleek wireless machine, Barr and his team spent an hour reworking the device based on both a poor CES reaction and cost-cutting engineering demands. One of the most recognizable pieces of electronics in the past four decades was the product of a quick rework, in other words.

Barr was influential well beyond those two early consoles. He designed key NES accessories, including the Zapper light gun and NES Max. And while Nintendo headquarters took the design reins in the mid-1990s, Barr left his stamp on the 2000s as well — he was involved in the design of the Wii and its legendary Nunchuk add-on controller.

In that light, Barr helped shape Nintendo's overall hardware design language: simple, sturdy and instantly recognizable. Nintendo appears to be in good hands without Barr, but his departure still marks the end of a long and important era.

Autonomous cargo hauling won't be limited to a handful of trucks and aircraft. As CNNreports, Yara International now expects to sail the first autonomous, fully electric cargo ship in Norway by the end of 2021. The Yara Birkeland will travel from Herøya to Brevik with only three remote control centers keeping watch over the journey.

Yara first developed the concept in 2017 and had planned to set sail in 2020, but the COVID-19 pandemic delayed the trip. It's not the first crewless ship of any kind to venture forth (a Finnish ferry launched in 2018), but it is the first all-electric model.

It's a slow vessel with a 13-knot top speed from its two 900kW propulsion systems (container ships typically travel at 16 to 25 knots), and it's safe to say the giant 7MWh battery will take a while to charge. However, Yara believes it will be worthwhile for the environmental gains. The firm estimated the Yara Birkeland would replace about 40,000 truck trips per year, dramatically reducing CO2 and nitrous oxide emissions in a country that already relies heavily on hydroelectric power. The ship could also alleviate traffic congestion on land, not to mention keep humans out of danger (albeit at the possible expense of jobs).

It may still be a long while before you see autonomous cargo haulers making trips elsewhere. Even if range isn't an issue, docks are — it would be harder for a self-sailing ship to navigate a busy port like Durban or Shanghai. There are also legal issues. Different countries have their own rules for the sea. As with self-driving cars, there's also the matter of liability. Who's to blame if an autonomous ship runs aground? While it's easy to see a day when autonomous electric ships are commonplace, that day likely isn't close at hand.
