Samsung has launched a walkie talkie app for its smartwatches similar to Apple's, giving you a way to chat with friends without having to make a call. By "smartwatches," though, we really just mean the Galaxy Watch 4 and Watch 4 Classic — the app, first spotted by XDA-Developers, only works with the tech giant's latest wearables and isn't compatible with any of their predecessors. 

That would limit the number of friends you can chat with, since they also need to own the latest Galaxy Watch. That said, the app's Google Play description says "two or more users" can have instant conversations, so you may be able to use the app outside of secret one-on-one chats in the middle of the night. Provided you know other people who have a Watch 4, of course, unless Samsung decides to roll the app out for its previous wearable.

To be able to use the feature, you need to log into your Samsung account on a phone connected to your watch. Samsung also recommends using and running the app for the first time while that watch is connected to a smartphone. After that, you'll be able to create channels for your conversation, connect to a nearby friend's watch and talk by pressing a big mic button at the center of the screen. You'll also be able to toggle the feature off any time you're feeling anti-social. 

The rumored satellite features for future iPhones are reserved for emergency uses only, according to Bloomberg's Mark Gurman. A few days ago, a report by well-known analyst Ming-Chi Kuo said the next iPhones will come with support for Low Earth Orbit satellite calls and messages. Gurman's sources said, however, that Apple isn't turning its devices into actual satellite phones, at least for now. Instead, the tech giant is reportedly developing at least two emergency-related features relying on satellite networks. 

The first feature is called Emergency Message via Satellite and will be added as a third protocol, alongside iMessage and SMS, to the Messages app. It's apparently codenamed Stewie inside the company and will allow users to text emergency services even when there's no signal, which sounds especially useful during emergencies in remote locations, such as mountains and forests.

The tool will also give users a way to text their emergency contacts simply by typing Emergency SOS in the recipient line. Messages will be restricted to a shorter length, but the senders' contacts will get a notification for them even if their phone is set to Do Not Disturb. Satellite messages will appear as gray bubbles instead of blue or green so they can be easily identified. Eventually, the feature could handle phone calls, as well.

Apple is also reportedly working on a second satellite feature that will allow users to report crisis situations like plane crashes and fires. This system will give users a way to report the incident at length and will ask them specifics, such as if anybody needs search-and-rescue services or if anybody in the vicinity is armed. It can also automatically send authorities the reporter's location and their details from the Health app, such as their medical history, age, medications and information like height and weight. The feature can also a notify the reporter's emergency contacts for them.

While both features sound useful, their availability is restricted by satellite location and reach. They might not work for some regions, and in some cases, users may have to walk outdoors in a certain direction where their iPhone can connect to a satellite. Also, Gurman's sources said it's unlikely that the features will be ready before the year ends, which means the next iPhones expected be announced sometime in September won't be able to send messages via satellite yet. 

Spectrum TV has made major streaming service additions to its digital cable service and live TV app with HBO Max and YouTube, parent Charter has announced. You'll be able to access both apps on channels 2004 for HBO Max and 2003 for YouTube, or on the platform's guide via the search or apps menu. You'll need, of course, a subscription to access HBO Max at $10 per month with ads or $15 ad-free. 

Along with Netflix, HBO Max and YouTube are the first streaming channels available directly through the Spectrum Guide. "As the video landscape continues to change, we are evolving our products and making it easier for our customers to watch what they want by providing access to streaming apps from convenient launch points within the Spectrum TV experience," said Spectrum VP Elena Ritchie.

As Spectrum notes, Warner's HBO Max offers 13,000 hours of premium content from brands HBO, DC, Cartoon Network, Adult Swim and Studio Ghibli. It also includes all 2021 Warner Bros. films (Dune, Godzilla vs. Kong and more) available the same day the films debut in theaters. That's a boon to movie fans not ready to go to theaters with the pandemic still raging, but a consternation to some of the filmmakers involved.

A group of current and former Apple workers recently banded together and called for colleagues to share stories of discrimination, harassment and retaliation they'd experienced within the company. As of August 27th, the group called #AppleToo said it has collected 500 such stories — now, it has started publishing them on its official Medium page. Cher Scarlett, an Apple security engineer and the face of the movement, wrote on Medium that she will share five stories at a time "as the emotional toll in reading these is heavy."

Two of the first five are about sexual harassment, one of which involved a male boss using his position of power over a female employee. Later, that employee was kicked out of an interview after the hiring team realized who she was. Another story was from a Black retail worker in the UK who tried to get their bosses to do something about racism and micro aggressions in the workplace to no avail. A female employee talked about how she was targeted by a person in her team and how management didn't do anything about it. And the last one is about an employee who was assaulted in her store by a customer and didn't get support from management. 

If Scarlett publishes all the submissions she got, these are just five of the many we'll get to read. The #AppleToo movement said on Twitter, however, that 75 percent share a common theme: They involve some form of discrimination. Nearly half of them involve sexism, retaliation and HR reports that were ultimately dismissed. A fourth of them involved racism and ableism, and most of the harassment and assault stories were sexual in nature. 

In an interview with Protocol, Scarlett said she feels "like the company needs to be held accountable because they're not holding themselves accountable. People want to feel heard. And they don't feel heard by Apple." She added that some employees who've been with the tech giant for decades felt like leadership used to listened to them, but that's no longer the case. 

When the news about the #AppleToo movement first broke, Apple said in a statement: "We take all concerns seriously and we thoroughly investigate whenever a concern is raised and, out of respect for the privacy of any individuals involved, we do not discuss specific employee matters."

When you factor in cars, trucks, planes, trains and shipping, the transportation sector is the largest source of greenhouse gases in the US. If we’re going to have any chance of addressing climate change, we’ll need to move away from burning fossil fuels in our cars. There’s just one problem with most electric vehicles: they depend on lithium-ion batteries made with heavy metals like cobalt. Not only is the material in short supply, but it’s mined in a way that involves child labor and the destruction of the environment. For those reasons, companies like IBM, Panasonic and Tesla have tried to make electric batteries without heavy metals.

So far, many of those efforts have yet to make it out of the lab, but a Chinese company called SVOLT claims it’s ready to start producing a cobalt-free battery at scale. At the Chengdu Motor Show, the firm showed off an 82.5KWh capacity power pack inside a vehicle from Chinese automaker Great Wall Motors. Under normal temperatures, SVOLT says its battery can deliver approximately 373 miles of range on a single charge and allow a car to accelerate from zero to 60 miles per hour in under five seconds.

SVOLT said the battery is “expected” to make its way to cars that go on sale in the Chinese market but didn’t offer a timeline of when that might happen, nor did it say just how many cobalt-free power packs it can manufacture at the moment. It's also worth pointing out other companies are making cobalt-free batteries at scale. As Electrek points out, most of the Model 3 units Tesla sells in China feature a lithium iron phosphate battery made by Contemporary Amperex Technology.

Twitch has lost one of its most popular and well-liked stars to rival YouTube. On Monday, Benjamin “DrLupo” Lupo announced he recently signed a deal to stream exclusively on YouTube Gaming. 

The deal comes nearly two years after Lupo signed an exclusive agreement with Amazon-owned Twitch, which was reportedly worth millions of dollars per year at the time. “We wish you nothing but the best in everything that comes next,” Twitch said after the streamer shared he was leaving the platform.

Loaded, the talent agency that represents Lupo, declined to share the details of his deal with YouTube, but the streamer told The Washington Post he’s now “secure for life.” He also told the outlet he plans to make more pre-recorded content. “Obviously, I’ll still be playing video games on YouTube,” he said. “But we have a chance now to do some new stuff.”

In moving from one platform to another, Lupo leaves behind the approximately 4.5 million followers he attracted to his Twitch channel. On YouTube Gaming, he has about 1.7 million followers, suggesting he may not, at least initially, attract the numbers he did previously. His first stream will air on August 31st.

Late Sunday evening, half of New York City’s subway system shut down for five hours due to a power surge, stranding hundreds of passengers in the process. New York Governor Kathy Hochul called it an “unprecedented system breakdown” of the Metropolitan Transportation Authority.

The Washington Post reports that the problems began when a power line went down. This triggered a voltage dip across the city, and two power plants and generators also went offline, forcing backup systems to come online. When trying to restore service, a power surge occurred. When this happened, the subway command center lost communications with 83 trains. The public address system also went down. Five trains with more than 550 people were stranded.

Part of the problem was the passengers themselves. While emergency personnel did evacuate as many people as they could, riders on two trains decided to leave cars on their own, a very dangerous act because tracks could be re-energized if a train was coming. Firefighters had to search the tracks to make sure there were no more remaining passengers before the subway could fully restore power.

After a phased “rolling restoration,” the system was finally back online at 1:30AM Monday morning.

Hochul has since ordered a deeper investigation into what exactly caused the surge as well as the other problems. So far, investigators have said there is no suspicion of terrorism or malicious actions.

Major cryptocurrency exchange Coinbase said it mistakenly told around 125,000 customers that their two-factor authentication settings had been changed. The email and SMS notifications were sent due to an "internal error" and were not the result of a hack, the company told CNBC.

Coinbase sent the false alert to users over the course of 82 minutes on Friday. It followed up with a second email stating that the message was sent by mistake. Coinbase later wrote on Twitter that a "notification delivery issue" was to blame and that it would "continue to work to gain back the trust of every one of our customers who was impacted by those notifications."

However, the issue appeared to cause confusion and concern among users, with some suspecting their accounts had been hacked. At least one person said they sold crypto worth around $60,000 because they were worried they'd lose it otherwise. 

That's an understandable concern in the wake of a CNBC report from last week, in which some Coinbase customers claimed their accounts were hacked and they couldn't contact employees for help. The company has since said it's rolling out voice and live chat support options.

PayPal is “exploring” the idea of allowing its users to trade individual stocks. Per CNBC, the company recently hired TradeKing co-founder Richard Hagen to head up a new unit at the company called Invest at PayPal. “Leading PayPal’s efforts to explore opportunities in the consumer investment business,” Hagan says of his new job on his LinkedIn profile. The outlet reports PayPal has also had discussions with potential brokerage partners.

Moving into retail trading wouldn’t be out of character for PayPal. The company has spent much of the last year expanding into the cryptocurrency market. It all started last October when PayPal announced it would let US users buy, sell and hold Bitcoin, Ethereum, Bitcoin Cash and Litecoin. PayPal CEO Dan Schulman also recently told investors the company could partner with different financial institutions to expand the number of services it offers. He even mentioned “investment capabilities” as one possibility. Either way, it’s a move that would make sense in the context of all the recent interest in retail trading that came out of the GameStop saga.

A PayPal spokesperson declined to comment on the report when we reached out.

Should PayPal decide to offer stock trading, it may take some time before it’s available to US users. CNBC reports PayPal is unlikely to roll out the service this year. And if the company decides it wants to operate as its own brokerage firm, it would need approval from the Financial Industry Regulatory Authority (FINRA). That’s a process that can take more than eight months.

Lego Star Wars: The Skywalker Saga won't arrive until next spring, but another game from the franchise is coming soon — and it's an Apple Arcade exclusive. Lego Star Wars Battles is a real-time strategy game that pits players against each other in one-on-one showdowns.

You'll amass a collection of upgradable characters, troops and vehicles from all eras of the Star Wars universe. You'll be able to pit porgs against Boba Fett, for instance. Don't expect to stick to one side of the Force — you'll have a deck of light side and dark side armies, with different play styles for each. You'll have a number of abilities at your disposal too, such as Darth Vader’s Force Slam and Luke Skywalker’s Force Push.

TT Games Brighton/Warner Bros. Games/Lucasfilm Games

Battlefields will feature Lego towers that you'll build, defend, attack and use to claim territory. The locations include some familiar environments, including Hoth, Naboo and Endor.

TT Games Brighton is developing Lego Star Wars Battles, while Warner Bros. Games is the publisher. It won't be the first Lego game to hit Apple Arcade, though. Lego Brawls and Lego Builder's Journey both landed on the service in 2019. The latter was ported to PC and Nintendo Switch in June.
