O AirPlay é a maneira mais fácil de transmitir conteúdos de um iPhone, iPad ou Mac para smart TVs compatíveis ou Apple TVs — sejam eles vídeos ou músicas.
Indo mais além dos aplicativos nativos da Apple que permitem isso, há os apps de terceiros que também podem suportar a tecnologia. Um deles é o TikTok, rede social de vídeos curtos. A partir de qualquer post, basta alguns toques para transmitir os conteúdos da rede no aparelho compatível.
Antes de mais nada, certifique-se de que o TikTok possui acesso à rede local. Para isso, abra os Ajustes (Settings), toque em “Apps” e em “TikTok”. Depois, marque a chave ao lado de “Rede Local”.
Abra então o TikTok e localize a postagem que deseja enviar. Mantenha o dedo pressionado por alguns segundos em cima dela, role pela lista e toque em “Transmitir”.
A Apple parece estar preparando seus sistemas para a nova leva de produtos que será lançada em breve. A menos de 24 horas do evento “Surprise and shine” (“Surpreendente e brilhante”), a empresa adicionou nada menos que 37 novos identificadores de hardware ao seu backend, abrangendo iPhones, iPads, Macs, Apple Watches e outros dispositivos.
A descoberta foi feita por Aaron Perris. No X, ele compartilhou todos os identificadores, sendo sete deles relacionados a iPhones.
A bunch of upcoming Apple device identifiers have been found on Apple’s backend. Interestingly, there are 7 iPhone models listed. We only know of 6.
O número chama atenção pois, até o momento, os rumores dão conta de seis modelos compondo a futura linha: “iPhone 18 Pro”, “iPhone 18 Pro Max” e “iPhone Ultra”, além dos “iPhone 18”, “iPhone Air 2” e “iPhone 18e” — os três últimos, segundo as notícias, só serão lançados no ano que vem.
Isso, porém, não significa necessariamente que a Apple esteja preparando um sétimo iPhone do qual nunca ouvimos falar. O identificador pode muito bem ser simplesmente uma variante de um dos modelos já esperados — como, por exemplo, uma configuração específica do “iPhone Ultra” destinada à China.
Além dos iPhones, a lista inclui nove identificadores de Macs, oito de iPads, nove de Apple Watches, um de Apple TV e três associados à categoria “HomeAccessory”, utilizada internamente pela Apple para produtos domésticos.
Lembrando que, no evento de amanhã, a Apple muito provavelmente lançará produtos como o “Apple Watch Series 12”, o “Apple Watch Ultra 4”, uma nova geração da Apple TV e, quem sabe, o aguardado hub inteligente para a casa — além dos iPhones, é claro. Novos Macs (como um iMac com chip M6 e a estreia dos “MacBooks Ultra”) e iPads (como o iPad mini com tela OLED), contudo, não são esperados para esta semana.

James Frith says patients may be less willing to share data as new figures show a rise in opt-outs
Concern is being raised about Palantir’s work with the NHS as new figures showed tens of thousands of patients have withdrawn their data from use in research projects.
James Frith, the health innovation minister, said he was worried about “mistrust” of the US defence and health tech company and “the impact it could have on people’s willingness to share data with the NHS”.
Smartphone longevity didn't used to matter. In the past, before you could wear out or break a phone, there was always some shiny new thing to buy. Today, we expect our smartphones to go the distance, but they've also become less repairable and, in many cases, more fragile. Fairphone, a Dutch smartphone maker that has just entered the US market, thinks about phones differently.
The new $650 Fairphone Gen 6+ is designed both for longevity and easy repairability. There are trade-offs to this approach if you're used to the standard glass and aluminum sandwiches filled with glue, gaskets, and teeny-tiny screws. But the drawbacks could be worth it for the right buyer. Fairphone CTO Chandler Hatton told Ars that Fairphone's goal is to provide a compelling mobile experience while also enabling the user to "fully own" their device. At the end of the day, this is what a lot of people say they want in a smartphone.
Take it apart, put it back together
These days, Google, Samsung, and Apple support phones with software updates for the better part of a decade, but will the hardware last that long? And what happens when it needs a repair? You may be out of luck or out a lot of money, but Fairphone prioritizes the self-repair experience.
Relocation coincides with proposed laws that opponents say would entrench power of US tech billionaires in country
Dozens of protesters converged on Peter Thiel’s mansion in Buenos Aires this week after a congressional session raised questions about the billionaire’s presence in the country.
In white masks, they held signs saying “Peter Thief” and “No to the Peter Thiel law” in front of the wrought-iron gates of the $12m (£8.9m) residence, which Thiel bought in April as he moved his family to Argentina.
For thousands of years, one of prehistoric Europe’s most lasting testaments to monumental architecture has stood along the coast of Brittany.
Hidden among the famous Neolithic monuments in this region of northwestern France is evidence of an earlier landscape—one whose ancient and enormous “standing stones” were occasionally broken apart, later to be reused by builders from successive ages.
France’s famous Locmariaquer megaliths include the Table des Marchands passage grave, the Er-Grah tumulus, and the extraordinary Grand Menhir Brisé, or Great Broken Menhir. Together, these ancient monuments preserve generations of ancient Europe’s monumental construction.
Yet among the most intriguing discoveries from this region are those related to the Table des Marchands itself. Specifically, the enormous, decorated capstone featured with this monument was once part of something else, and its remains preserve evidence of a much earlier massive freestanding stone monument.

A Neolithic Jigsaw Puzzle
During work at the passage tomb of Gavrinis, located on an island roughly four kilometers away, a chance discovery eventually led archaeologists to a breakthrough.
Several decades ago, archaeologist Charles-Tanguy Le Roux had been examining the once-concealed upper surface of the massive capstone, which covers the ancient tomb structure’s main chamber. During his inspection, it became evident to Le Roux that engravings on its surface appeared to be something more than just unique designs etched onto the capstone; they were a continuation of other designs found at the Table des Marchands.

Additional pieces of this Neolithic jigsaw puzzle began presenting themselves nearby, and once reconstructed, the long-separated slabs now seemed to indicate that they had once formed portions of a single monumental, decorated stone, once measuring an astounding 14 meters in length and weighing close to 100 tons.
Over time, fragments of the original monument had apparently been separated and incorporated into different later structures—a discovery that offered evidence of megalithic recycling in the ancient world.
The recycling of monumental ancient fixtures was common in the ancient world. Well-known examples include the reuse of stone blocks from construction sites in Egypt for later monuments. Also, a recent discovery in Turkey revealed that a massive, ancient Lydian-era statue was later broken into two pieces and used as part of a roadway during the Roman era.

An Earlier Monumental Landscape
At the Table des Marchands, the reconstructed stone had been adorned with engravings that included depictions of ancient bovines, as well as symbolic motifs. Originally, it is believed this megalithic marvel once stood as part of an earlier monumental complex in the area, which was toppled and fragmented at some point.
That earlier landscape included the Grand Menhir Brisé, or “The Great Broken Menhir,” a massive megalithic stone that once towered over the site, erected by ancient engineers around 4,700 BC. At the time this megalith stood upright, it measured almost 70 feet in height and weighed some 330 tons, making it one of the most extraordinary engineering achievements known from Neolithic Europe.

Sometime around 4,000 BC, the massive stone megalith toppled over, and today its remains are preserved in four large broken pieces adjacent to the Table des Marchands. Archaeologists believe that it may have once belonged to an alignment of large standing stones erected around the fifth millennium BC.
With time, the large standing stones were brought down, and while ending an ancient megalithic tradition, at least some portions of these ancient monuments saw later reuse in newer monuments. Fragments of these much earlier, highly decorated stones made their way into the nearby tombs, which can still be seen in these monuments today—including the famous capstone at the Table des Marchands, and the massive slab at Gavrinis.
Why Dismantle a Monument?
The exact reason these enormous ancient monuments were dismantled remains unknown, although archaeologists have proposed a few theories.
Such reuse may have been entirely practical and seen as a means of borrowing from available resources present in the landscape when a later need arose. Another possibility is that there may have been a deeper significance to such practices, whereby the addition of fragments from earlier monuments into newer ceremonial or funerary structures may have imbued these newer structures with the essence of the past.
Doing so may have allowed Europe’s ancient Neolithic engineers to preserve connections to their ancestors and establish continuity between past and present as newer monuments were constructed.
Alternatively, it may have been that instead of trying to preserve ancient traditions, later builders who reused components from these monuments may have been deliberately rejecting earlier social or religious ideas by using smashed remnants from those periods in newer constructions.
Amid such questions, the enigmatic capstone of the Table des Marchands offers a unique look at Europe’s remarkable prehistoric engineering, surviving as a fragment of older times that found new purpose in one of Neolithic Brittany’s most intriguing ancient monuments—and pieces to an ancient puzzle that will likely remain unsolved.

Casimir Inc., a technology startup that made headlines with its controversial vacuum energy chip, MicroSparc, has received a financial award from the United States Air Force Research Lab’s SpaceWERX to advance the technology toward practical defense applications.
According to a company statement, the Phase I award, part of the Department of the Air Force’s (DAF) broader Small Business Technology Transfer (STTR) program, will fund Casimir to explore the technical viability of its vacuum energy chip, which The Debriefpreviously revealed exclusively.
Although a Phase I award does not guarantee future financial support, the new ‘proof-of-concept and potential’ award could put Casimir in line for future Phase II and Phase III awards from SpaceWERX, depending on the success of this phase.
The company told The Debrief that Casimir’s goal “remains full commercialization of MicroSparc by 2028.”
SpaceWERX Award Will Assess Feasibility of Casimir’s MicroSparc Technology
According to the SpaceWERX site, STTR Phase I grants are awarded to companies to “prove the technical merit and commercial viability of your innovative idea.”
“SpaceWERX manages the United States Space Force’s Small Business Innovation Research (SBIR) and Small Business Technology Transfer (STTR) programs, awarding contracts to startups and small businesses developing technologies with commercial and defense applications that strengthen the U.S. defense industrial base since 2019,” the SpaceWERX site explained.
Although Casimir did not provide financial or timeline specifics, SpaceWERX guidelines indicate these awards typically range from $75K to $180K and last three to 12 months. As an “Open Topic” award, Casimir’s work will also include what the SpaceWERX site describes as “a critical customer discovery phase.”
The company said the new award will allow the team to focus on “developing Casimir’s fully independent solid-state generator to address the most pressing challenges in the Department of the Air Force (DAF).”
“The Phase I work is focused on validating Casimir’s independent solid-state generator design against DAF requirements for systems operating in remote or hard-to-service environments,” a company spokesperson told The Debrief. “This is especially notable because it expresses a desire and need for Casimir’s tech in mission-critical environments.”
“The Underlying Physics” Are Not New
Former NASA Eagleworks researcher and Casimir co-founder Dr. Harold G. “Sonny” White later pursued research involving engineered Casimir cavities at the Limitless Space Institute, including work supported by the Defense Advanced Research Projects Agency (DARPA).
“This concept became a central part of our DARPA Defense Sciences Office (DSO) research effort at the Limitless Space Institute, where DARPA funded early theoretical and experimental investigations into custom Casimir cavity structures and their interaction with the quantum vacuum,” White previously told The Debrief.
Although the company previously said it already has functioning prototypes, many scientists have challenged the technology’s validity, with some labeling the MicroSparc a “perpetual motion” machine that violates the laws of physics. When describing the concept to The Debrief, Dr. White seemed to anticipate those criticisms, noting that MicroSparc takes advantage of established quantum physics principles, clarifying that the technology does not violate basic physics principles.
“The underlying physics itself is not new,” White told The Debrief.
Instead, the former NASA scientist noted that the Casimir effect “has been part of established quantum mechanics since the mid-20th century and has been experimentally verified by laboratories around the world.” MicroSparc, he explained, is based on that science.
MicroSparc, White argues, builds on that established physics, although the company’s much more consequential claim—that its device can produce continuous usable electrical power from the quantum vacuum—has not been independently demonstrated.
“In our device, the quantum vacuum outside the cavity walls vigorously stimulates electrons in the wall atoms,” Dr. White previously told The Debrief. “Occasionally, an electron will quantum tunnel from the wall to one of the central pillars.”

For clarification, quantum tunneling is a well-established quantum phenomenon in which a particle has a finite probability of crossing an energy barrier that it could not overcome according to classical physics. The effect has been repeatedly demonstrated experimentally and underlies technologies ranging from scanning tunneling microscopes to semiconductor devices.
“Once inside the protected cavity, the environment is far quieter, (so) the probability of the electron tunneling back to the wall is orders of magnitude lower,” White told The Debrief.
White said this phenomenon creates a one-way flow of electrons toward the pillars, a process he compared to “a kind of quantum ratchet.” By fabricating millions of these microscopic cavities on a single chip, White said his team was able to produce “a continuous electrical current drawn from the quantum vacuum.”
Refining the Vacuum Energy Concept for a Fully Independent Generator
When discussing the significance of the award, especially given the controversial nature of vacuum energy concepts, the company told The Debrief that the award is “a signal to the market and community that this tech is pivotal and up-and-coming…now with gov’t resources.”
Dr. White agreed, noting that “This Phase I award is an important step in exploring how Casimir’s solid-state power technology could support national security missions where persistent, reliable power is essential.”
“As a producer of quantum energy technology, this project will allow the Casimir team to refine the concept for a fully independent generator while working with potential customers to better understand the requirements of systems operating in austere and difficult-to-service environments.”
Moving forward, the company told The Debrief that its goal remains targeting commercial availability of Casimir’s MicroSparc chip by 2028, “positioning the company to disrupt the ultra-low-power electronics sector.”
“The DAF began offering the Open Topic SBIR/STTR program in 2018, which expanded the range of innovations the DAF funded, and now, in August 2026, Casimir will continue its journey to create and provide innovative capabilities that will strengthen the national defense of the United States of America,” the company’s statement explained.
“Much of modern electronics is constrained by batteries, charging cycles, wiring, maintenance, or environmental limitations,” Dr. White told The Debrief. “If this technology scales successfully, its long-term implications could extend from ultra-low-power sensors and consumer electronics to remote infrastructure, defense systems, and eventually space applications, where persistent power is especially valuable.”
Although Phase I STTR awards are a necessary step toward larger Phase II and Phase III awards, which are designed to take emerging technologies proven in Phase I to the market, the company told The Debrief, “it’s way too soon” to realistically think about those steps, while acknowledging the possibility “down the line.”

Amazon wants to grow its Prime Air delivery drone service sixfold to reach nearly 500 cities and towns across the United States by the end of 2026. The planned expansions from Amazon and its rivals could make the convenience of delivery drone services available to tens of millions more people in the coming months—but will also test more communities’ tolerance for increased noise from daily drone flights.
On August 19, Amazon announced it would soon launch Prime Air in the metropolitan areas of Chicago; Cleveland; Atlanta; Syracuse, New York; and Boise, Idaho, with more to come later in the year. Each Prime Air site offers delivery drone service within an area of about 175 square miles, with delivery times ranging from half an hour to an hour.
Prime Air already operates out of Amazon warehouses in 10 cities across seven states. Those include primarily suburban neighborhoods of Phoenix; Tampa; Kansas City; Omaha, Nebraska; Baton Rouge, Louisiana; Detroit; Houston; and San Antonio, Dallas, and Waco, Texas.

The first flight of the largest battery-electric aircraft to take to the skies lasted nearly half an hour while costing just $5 of electricity. That aviation feat comes at a time when jet fuel prices have skyrocketed because of the US war with Iran.
The test flight of Heart Aerospace’s X1 demonstrator aircraft took place at Plattsburgh International Airport in upstate New York on August 12. The X1 aircraft is comparable in size to a small regional airliner and can achieve a maximum takeoff weight exceeding 25,000 pounds with the help of four wing-mounted electric motors. The battery-electric propulsion system delivered more than one megawatt of power during the maiden flight.
All-electric aircraft can offer quieter and cleaner flight without the emissions that come from burning jet fuel. They may also prove more reliably cost-effective than conventional aircraft that come with jet fuel costs subject to geopolitical disruptions.

BOE wants a share of the OLED supply chain for Apple's next iPad Air, aiming to land a secondary sourcing role behind primary supplier Samsung Display, according to a report from South Korea's The Elec.
Sources cited by The Elec say the Chinese panel maker is building out its iPad Air OLED effort at its B12 fab in Chongqing, home to BOE's sixth-generation OLED production line, ahead of the launch of a redesigned iPad Air that isn't expected to launch until the first half of 2027. Samsung Display already holds the lead supply role for that panel and is on track to begin ramping production toward the end of this year or the start of next, as previously reported.
BOE still has to clear Apple's qualification process. Samples reportedly still need to be submitted for evaluation, and a verdict on whether the company wins any commercial orders is not expected until closer to the end of the year. Even a favorable outcome may only translate into modest volume at first, with output confined to iPad Air units destined for the Chinese market or to refurbished devices, rather than the entire global launch.
The sources put BOE's qualification decision at some point in November or December, noting Apple typically finalizes production approval just one to two months ahead of mass production actually starting. Should BOE fall short of that bar, Samsung Display will end up carrying the entire initial production run by itself.
Becoming a supplier for the OLED iPad Air would be a meaningful expansion for BOE, which has experience providing OLED panels for the iPhone, but has struggled to break into larger OLED products. Samsung Display and LG Display have held onto that ground in tablets specifically, and BOE has lost, rather than gained, footing elsewhere in Apple's OLED lineup recently; its utilization on Apple-dedicated lines reportedly slid from roughly 82% in 2024 to about 48% earlier this year as Apple is set to lean on Samsung instead for the upcoming OLED iPad mini.
The redesigned iPad Air is expected in 11 inch and 13 inch sizes, with a hybrid OLED panel pairing a glass substrate with thin film encapsulation, a single stack RGB emissive layer, and an LTPS backplane, with a refresh rate of 60Hz. That keeps it below the iPad Pro's tandem stack OLED panel on cost, while still moving the iPad Air away from an LCD.
BOE is also reportedly pursuing a secondary supplier role for Apple's OLED MacBook Pro from its 8.6 generation B16 fab in Chengdu, but persistent yield problems there make commercial shipments to Apple unlikely soon. Industry sources do not expect BOE to enter that supply chain until sometime after 2028.

As Elon Musk, Peter Thiel and their peers have grown richer and more influential, Gil Durán argues they have all but abandoned democracy – and found the perfect government to enable them
In April, Gil Durán was permanently banned from Elon Musk’s X for posting just two words. Durán was responding to a post from the tech company Palantir outlining its 22‑point “technological manifesto”, which praised American “hard power”, western culture and AI weapons, denounced inclusivity and called for compulsory national service. Durán responded: “TLDR: Fascism” (TLDR is short for “too long, didn’t read”).
Durán didn’t break any of X’s written rules, he points out over a video call from San Francisco – so much for Musk’s “free-speech absolutism”. His ban might just have had something to do with his preceding tweet, showing the cover of his new book, The Nerd Reich: Silicon Valley Fascism and the War on Democracy. The book’s central argument is that big tech is no longer our friend, as many of its billionaire owners have seized economic and political control and are steering the fate of the planet towards their own bizarre, apocalyptic visions.
The iPhone Air reaches one year on sale next month, and Apple is now closer to launching its successor than it is to the original's debut. On this week's episode of The MacRumors Show, we discuss what's next for the device.
The first-generation model has had a difficult run. A KeyBanc Capital Markets survey found virtually no demand for the device within weeks of its September 2025 launch, supply chain analyst Ming-Chi Kuo reported that suppliers were asked to cut capacity by more than 80% between launch and early 2026, and Luxshare and Foxconn both wound down production, leaving the phone believed to be entirely out of manufacture. Apple discounted it heavily in March, and SellCell data put its ten-week depreciation at 44.3% on average, against 34.6% for the iPhone 17 series. The Weibo leaker known as "Digital Chat Station" said in May that the device had barely surpassed 700,000 activations even after multiple rounds of price cuts.
A single rear camera left a $999 phone looking less capable than the cheaper iPhone 17, which has two, and the absence of the iPhone 17 Pro's vapor chamber cooling means the Air runs warmer under load. It also lacks stereo speakers. Battery life falls short of a full day for many users, mitigated in part by the dedicated MagSafe battery accessory Apple sells alongside it. With the iPhone 17 Pro starting at $1,099, the Air occupies a $100 gap that gave buyers little reason to stop there.
Almost every change rumored for the second-generation model targets one of those points. Bloomberg reported in June that Apple will add an Ultra Wide lens alongside the existing 48-megapixel Fusion camera, and that the dual-lens design has reached advanced testing with the same exterior as the current model save for the extra lens.
Almost everything other than the battery sits inside the iPhone Air's camera plateau, and Apple has reportedly asked suppliers for an ultra-thin Face ID module to free up space. The company also plans to adopt Samsung's CoE display technology, which is thinner and brighter than the current panel and debuts first on the foldable iPhone. Digital Chat Station expects a 3,500mAh battery, up from 3,149mAh, and The Information reported that Apple wants the device to be lighter and to gain vapor chamber cooling despite the added hardware.
The device will also likely feature the A20 Pro chip, binned in some form like its predecessor, along with Apple's second-generation N2 wireless networking chip, the C2 modem, and 12GB of RAM, unchanged from the current model. Externally, little is expected to change beyond the additional rear camera, but Pu expects a slightly smaller Dynamic Island, in line with the wider iPhone 18 lineup. A lavender color option could replace Sky Blue.
Pricing is the biggest open question. The Information reported that Apple is considering a lower price for the second model, but the surrounding lineup is moving too. Pu expects the iPhone 18 Pro and Pro Max to cost $250 to $300 more than the current Pro models owing to 2nm silicon and memory costs, and the foldable iPhone is rumored to start somewhere between roughly $2,000 and $2,500. A widened gap between the Air and the Pro tier could change the calculation that undermined the original, particularly once the camera disparity with the standard iPhone disappears.
Apple's confidence in the fall lineup appears to be growing in the meantime. The company reportedly told suppliers to prepare roughly 10 million foldable iPhones this year, up from an earlier forecast of seven to eight million, and has booked parts for around 80 million smartphones in the second half of 2026. Samsung, meanwhile, says the Galaxy Z Fold 8, Z Fold 8 Ultra, and Z Flip 8 drew 1.44 million pre-orders in South Korea across seven days, a company record, with the redesigned Z Fold 8 accounting for close to half of them.
The iPhone 18 Pro, iPhone 18 Pro Max, and foldable iPhone are expected in September, and Apple has already begun preparing for the event, opening a lottery for U.S. retail employees to staff it.

FaceTime Dual Capture is bringing simultaneous front-and-rear camera streaming to video calls in iOS 27, allowing compatible iPhones to show the caller and their surroundings without repeatedly switching between cameras.
The feature expands technology Apple introduced with the iPhone 17 family. Dual Capture already allows the Camera app to record through the Center Stage front camera and a rear camera at the same time. iOS 27 brings a similar capability directly into live FaceTime calls.
During a call, the front camera can continue showing the speaker while the rear camera displays whatever the iPhone is pointing toward. Someone attending a concert can share the performance and remain visible. A parent can show a child playing without disappearing from the conversation. A person asking for technical assistance can remain on screen while directing the rear camera toward the equipment causing the problem.
Dual Capture removes the awkward sequence of switching to the rear camera, showing something, and switching back to continue speaking face to face. Both perspectives remain available inside the same call.

FaceTime Dual Capture Changes Camera Switching
The normal FaceTime camera control changes from a simple front-or-rear choice on supported iPhones. When the caller activates the rear camera, iOS 27 keeps the front camera visible by default.
The main view displays the rear camera feed while a smaller window contains the front camera image. This picture-in-picture arrangement gives the other participant a continuous view of the caller’s reaction, commentary, or explanation.
To activate both cameras during a supported FaceTime call:
FaceTime > Start a video call > Tap the Flip button
Tapping the Flip button turns on the rear camera without immediately removing the front view. The other participant begins receiving both perspectives as part of the FaceTime stream.
The caller can disable the front view when it is no longer needed. This provides a conventional rear-camera presentation for situations where the surroundings should occupy the complete image.
To return to a single camera view:
FaceTime > Tap the camera view > Disable the front camera
The exact labels and placement may change before the public release of iOS 27 because the feature is still being tested in beta software. Its basic behavior is already established: the Flip control activates the rear camera while retaining the front camera feed.
Dual Capture does not create two independent FaceTime calls. Both images belong to one video stream, so the caller does not need a second account, device, or invitation.
The feature also differs from screen sharing. FaceTime screen sharing transmits applications and interface activity from the iPhone display. Dual Capture transmits live video from two physical cameras.

Which iPhones Support Dual Capture
Apple has limited FaceTime Dual Capture transmission to the iPhone 17, iPhone 17 Pro, iPhone 17 Pro Max, and iPhone Air. Each model includes Apple’s 18MP Center Stage front camera and the Dual Capture capability introduced in the Camera app.
An older iPhone that supports iOS 27 cannot originate a Dual Capture stream. It continues to use the normal option of selecting either the front camera or a rear camera during a call.
Older models can still receive and display a Dual Capture feed when they are running iOS 27. This allows an iPhone 16 or another supported device to see both views transmitted from an iPhone 17, even though it cannot send the same presentation back.
Both participants need iOS 27 for the new FaceTime layout to work as intended. The transmitting device must also be one of the supported iPhone 17-generation models.
This limitation is based on Apple’s official feature support rather than the simple presence of front and rear cameras. Earlier iPhones have camera hardware capable of operating in several multi-camera applications, but Apple has not extended its native Dual Capture implementation to them.
Third-party applications have offered forms of simultaneous multi-camera recording for years through Apple’s developer frameworks. The difference is that iOS 27 integrates the experience into FaceTime, where users can activate it through the familiar camera-switching control.
iPhone 17 Owners Receive a Second Dual Capture Feature
Describing FaceTime Dual Capture as retro-compatible with the iPhone 17 does not fully explain its relationship with the hardware. The iPhone 17 family introduced Apple’s native Dual Capture recording in 2025, and iOS 27 now gives that existing camera system another purpose.
Inside the Camera app, Dual Capture produces a saved video containing front and rear views. Apple lists support for recording at up to 4K Dolby Vision at 30 frames per second on the iPhone 17.
FaceTime uses the camera pairing for live communication instead. Network quality, bandwidth, device temperature, and FaceTime processing can affect the transmitted resolution, so users should not assume that a call will preserve the Camera app’s maximum 4K recording specification.
The Center Stage front camera also contributes more than resolution. Its square sensor gives the iPhone greater freedom to adjust framing without requiring the device to be physically rotated. Center Stage can help keep the caller positioned inside the smaller front-camera view while the rear camera follows the subject being shared.
That combination makes Dual Capture more useful than placing two untreated camera feeds beside each other. FaceTime can preserve the speaker’s presence while directing most of the screen toward the event, object, or location being discussed.
The feature may require more processing power and energy than an ordinary single-camera call. Running two camera sensors while encoding and transmitting live video can increase battery consumption and device temperature, especially during long calls over cellular data.
Apple has not published separate battery estimates for Dual Capture FaceTime calls. Users planning extended sessions may want access to power and a stable Wi-Fi connection.
iOS 27 Prepares FaceTime for iPhone 18
FaceTime Dual Capture arrives shortly before Apple’s expected iPhone 18 generation, making it likely to become part of how the company demonstrates the new phones’ camera and communication abilities.
Apple has not announced the iPhone 18 lineup or confirmed its final camera specifications. Compatibility with FaceTime Dual Capture is therefore expected from the software’s “iPhone 17 and newer” positioning, but individual iPhone 18 models should not be treated as confirmed until Apple presents them.
The software release gives existing iPhone 17 owners access without requiring another hardware purchase. That approach also provides Apple with a working FaceTime feature before the next iPhone launch rather than introducing the camera mode and communication interface at the same moment.
Future hardware could improve the experience through faster processors, stronger image stabilization, upgraded sensors, or more efficient video encoding. None of those additions is required for the supported iPhone 17 family, which already contains the camera system needed to transmit both views.
Dual Capture is only one part of the FaceTime update. Apple is also improving video-call quality when the network connection is weak, addressing a problem that becomes especially relevant when two live camera views require transmission. Traditional Chinese support is joining FaceTime Live Captions as well.
The weak-connection improvement may determine how dependable Dual Capture becomes away from Wi-Fi. A feature designed for travel, events, repairs, and outdoor calls needs to tolerate changes in cellular bandwidth without freezing both views or forcing the session to end.
FaceTime Dual Capture remains part of the iOS 27 beta as Apple prepares the public update for September. Apple can still adjust the interface, performance, device requirements, and picture-in-picture behavior before the completed software reaches iPhone 17 owners.
