Eight Sleep raises $100M to expand it AI-powered sleep tech | TechCrunch

Roughly one in three adults in the U.S. regularly gets insufficient sleep, driving demand for tools that can monitor, analyze, and enhance rest. Eight Sleep, founded in 2014, offers AI-powered sleep tech products that promise to transform your bed into a preventive health device.

The New York-based startup announced Tuesday that it raised a fresh $100 million round from investors such as HSG, Valor Equity Partners, Founders Fund, Y Combinator and athletes including Ferrari F1 driver Charles Leclerc, and Zak Brown, who is the CEO of McLaren F1.

With this round, Eight Sleep has raised roughly $260 million total, Pitchbook estimates. It previously raised an $86 million Series C in 2021 by investors who assigned it a $500 million post-money valuation. Eight declined to reveal its current valuation.

“If we successfully execute our AI roadmap, launch internationally, and develop condition-specific interventions, achieving unicorn status will naturally follow,” Alexandra Zatarain, co-founder and CMO of Eight Sleep, told TechCrunch.

Eight offers smart mattresses that integrate software and AI to track and enhance sleep quality. Its flagship product, Pod, offers features like measuring sleep stages, heart rate, breathing patterns, and movement. Using these insights, it automatically adjusts temperature, elevation, and firmness. It can also detect snoring and automatically elevate the base in response, according to the company.

The company has generated more than $500 million in Pod sales, expanded its revenue tenfold since launching the product in 2019, and collected insights from over one billion hours of recorded sleep data, it says.

Eight, which employs just over 100 full-time staff, is now expanding beyond the Pod with its Sleep Agent, an AI-driven system that leverages large language models to create thousands of digital twins for each user and predict outcomes, with the goal of optimizing nightly recovery. This approach shifts sleep technology from reactive tracking to proactive, personalized intervention, said Zatarain.

The sleep tech market features a range of competitors, from wearable devices such as Oura, Fitbit, and Apple, to medical-focused companies like ResMed, as well as smart mattress and sleep surface makers, including Sleep Number and ChiliSleep.

Eight’s core differentiator, Autopilot, “builds a personal blueprint from night one, then adapts continuously, accounting for seasonality, travel, stress, training, illness, or even a bad night before. And it works independently for each side of the bed,” Zatarain said.

The startup plans to use the new funding to accelerate its growth in the medical sector, building on the Pod’s health-monitoring capabilities. With the introduction of Health Check, the system can monitor cardiovascular and respiratory patterns with up to 99% accuracy without the need for wearable devices, according to the company.  

“We’re not replacing your doctor, but we are giving you nightly, high-accuracy health monitoring so you can act early if trends shift. Over time, this data can complement medical care,” Zatarain said.

Eight’s recently launched Hot Flash Mode employs AI-driven cooling to relieve menopause symptoms. It is also working on contactless solutions for sleep apnea. The company is pursuing FDA approval and will utilize the Pod’s real-time biometric monitoring to deliver personalized interventions.

Eight Sleep currently ships to over 30 countries—including Canada, the UK and EU nations, Australia, Mexico, and the UAE—and is now planning to expand into China. The CMO told TechCrunch that China, as one of the world’s largest consumer markets, is seeing a rise in a health-conscious middle class that prioritizes sleep and overall wellness.

Regarding sensitive health data, Zatarain said the company complies with each locale’s regulations, including for data storage.

“Privacy is foundational. All data is encrypted, never sold, and fully private. We comply with GDPR and CCPA, and unlike many devices, we don’t use microphones. Our biometric sensors are embedded in the bed surface — no wearables, no invasiveness, just passive, high-accuracy insights,” Zatarain said.

Samsung’s Galaxy Z Fold 8 is the best phone (not just foldable) I’ve ever used for consuming content—watching videos, playing mobile games, reading, and yes, even doomscrolling social media—thanks to its 7.6-inch inner screen.

The book-style foldable phone’s novel shape when closed may look strange at first, but I promise you that its shorter and wider footprint (when closed) quickly feels normal after a few days. The whole point of this form factor is to unfold it for its larger tablet-sized screen, and I can assure you that you’ll be doing that often because the experience encourages it more.

More importantly, the Z Fold 8 has fewer of the compromises that held back Samsung’s previous foldable phones. The device is lighter and easier to unfold, the battery is bigger and lasts all day, and Samsung has greatly reduced the crease on the inner screen.

Some apps still might not display correctly on both screens, but even so, I’m declaring the Z Fold 8 a home run. I can’t stop using it.


Samsung Galaxy Z Fold 8

The Galaxy Z Fold 8 is Samsung’s best version of a book-style foldable phone yet, even with its premium price.

  • Thin and light
  • Gorgeous AMOLED screens
  • Crease is greatly reduced and flat
  • All-day battery life with faster charging
  • Solid cameras
  • Easy to use with one hand
  • Quick Share works with Apple AirDrop
  • Inner hole punch camera can block content
  • Can get warm for no reason
  • Only IP48 rating
  • No built-in magnet ring for wireless charging
  • Some apps aren’t optimized properly

The best size comparisons for the Z Fold 8 are a passport or a B7-sized notebook. The foldable measures 4.88 x 3.24 inches when it’s closed. It’s a few hairs thicker than the Z Fold 8 Ultra, but because of the squatter dimensions and lighter weight, the Z Fold 8 doesn’t feel unwieldy. I’m mostly able to reach corner to corner on the 5.5-inch AMOLED cover screen, something I haven’t been able to do on any “regular” (read: 6 to 6.9-inch) bar-style phone in years.

It also fits in my front pants pockets better than expected; I had concerns that the width might be too wide. I guess if you’re already used to the width of an iPhone 17 Pro Max or a Galaxy S26 Ultra, the Z Fold 8’s only slightly wider.

I’m able to reach the power button/fingerprint reader easily with my right thumb. Lefties might struggle since they can’t use their thumb and will have to register their index finger, which might be a little stretch to press the button, like it is for me. The volume rocker is a little high for me; I prefer its lower position on the Z Fold 7/Z Fold 8 Ultra. Typing with two hands on the cover screen is a much easier affair than on narrower phones; I made fewer typos compared to my iPhone. One-handed typing will depend on whether your hand is large enough and your thumb can stretch across the keyboard.

The 10:16 aspect ratio of the cover screen is also not as cramped as it seems. You lose vertical space compared to most regular phones and taller foldables like the Z Fold 8 Ultra, which means apps will show less and you’ll need to scroll more, but that’s mostly a non-issue if you open the phone and rotate it to vertical orientation. I never found myself bothered that I couldn’t see enough on the cover screen. If anything, I appreciated the shorter screen more because I didn’t feel compelled to pull it out as much unless I wanted to unfold it.

Like on the Z Fold 8 Ultra, you can use the Z Fold 8 in “tent” mode. This is great for propping up the device on a plane tray table or if you’re just too lazy to hold it up while in bed. I fly a lot for work, so tent mode is something I find very useful. A Z Fold 8 Ultra feature that you won’t find on the Z Fold 8 is “Flex mode.” On the Z Fold 8 Ultra, you can snap the screen so that it resembles a baby laptop, and some apps, like YouTube, will display the video above the crease and controls below it. I never found much utility for Flex mode on the previous Z Folds and I don’t miss it on the Z Fold 8. If that’s something you care about, get the Z Fold 8 Ultra instead.

Out of all the book-style foldable phones I’ve tested over the past seven years, the Z Fold 8 is the only one that I have unfolded more times than I have not. With each generation of Z Fold, Samsung made the dimensions more like a regular bar-style phone. I heaped praise on the Z Fold 7 for finally ditching the previous skinny, remote-like shape. And even though I considered the Z Fold 7 my favorite Android phone of 2025, I realized that I only used its inner screen maybe less than 50% of the time I pulled it out. With the cover screen being normal-sized, there just wasn’t as much of a need to unfold it for the 8-inch screen.

That hasn’t been the case with the Z Fold 8. Because of the shorter cover screen, I almost always unfold it to use the larger display. Maybe that’s because the Flex Titanium technology helps the hinge spring open better or the beveled aluminum frame makes it easier to unfold without needing fingernails, or both. Whatever the reasons are, it’s easier to see and feel the benefits of the larger size of the inner screen’s 4:3 aspect ratio for most content than on a more square-ish folding screen like the Z Fold 8 Ultra’s. To get roughly the same diagonal screen for widescreen videos on the Z Fold 8 Ultra, you need to rotate it, which is an extra step. It’s a tiny bit of friction that makes the task of quickly unfolding and getting more screen real estate less convenient. When you’re unfolding the phone dozens of times a day, that one extra step adds up.

After two weeks of using the Z Fold 8 and Z Fold 8 Ultra, I’ve concluded that if you watch more videos and game more than you read, the Z Fold 8 is the better foldable since you won’t need to rotate it so much. If you do more reading and split-screen multitasking, the Z Fold 8 Ultra is more suitable since you’ll get more vertical display on both the cover and inner screens without rotating, and you’ll do less scrolling.

I consume a ridiculous amount of content on a daily basis, so I find the 4:3 aspect ratio more versatile for my needs. In just two weeks, I watched, gamed, and read more on the Z Fold 8 than I have on any new phone I’ve ever tested. Videos look incredible on the 7.6-inch inner screen; 16:9 videos have minimal letterboxing (black bars) above and below them, and old content like many original anime series in 4:3 aspect ratio fill up the entire screen. I’ve never felt more informed and entertained from my phone.

As with the Z Fold 8 Ultra, the Z Fold 8 lets you run three apps in split-screen layouts or four (with a pop-up) on the inner screen. I wouldn’t recommend running more than two apps side by side in landscape orientation. Three apps side by side make each app window very skinny, and one app on one side and two stacked on the other half feel squished. Split-screen apps in vertical orientation just look too long to be useful in most cases. In some split-screen layouts, Samsung’s One UI 9 does let you tap between split-screen apps to have it fill more or most of the screen, but it’s not a function that’s easy to discover.

Performance from the Qualcomm Snapdragon 8 Elite Gen 5 for Galaxy chip is snappy and the 12GB of RAM on my 256GB review unit (you’ll get 16GB if you buy the 1TB model) never chugged when I threw Gemini and Galaxy AI tasks at it. The only thing that occasionally bugs me is that the Z Fold 8 gets toasty even when I’m not doing anything power-hungry. I suspect the super-thin design doesn’t leave much room for adequate thermals; there’s no vapor chamber for cooling like there is on the Galaxy S26 Ultra and iPhone 17 Pro.

The inner screen has been a joy to use, especially on my 1-hour subway commute to and from work. And instead of reaching for my iPad mini in bed, the Z Fold 8 now fills the role instead. It’s great only having to charge one device.

On the topic of charging, the Z Fold 8’s battery is rock solid, lasting me a full day even with heavy use of the inner screen. That’s not surprising since Samsung added a small percentage of silicon carbon into the 4,800mAh battery, which allows for the larger cell while maintaining a slim size. The 45W fast wired charging, with a compatible charger sold separately (of course), was more than quick enough to give me a recharge (around 0% to 65% in 30 minutes) whenever I was low on power. The Z Fold 8 also supports fast wireless charging at 20W, but I used it less compared to other phones like the iPhone 17 Pro or Pixel 10 Pro because Samsung still refuses to include built-in magnetic charging rings. You, again, need to buy a case with magnets to align the phone effortlessly with a Qi2 charger.

The only blemish, literally, on the larger screen experience is the 10-megapixel hole-punch camera on the inner screen. It can obscure essential parts of a menu, buttons, or text depending on what you’re looking at. For example, in Asphalt Legends, I couldn’t see a menu button that the hole punch covered. The hole punch is most noticeable when reading long blocks of text or black and white manga. It makes more sense to put the camera in the corner since it can’t fit in a bezel like on a regular tablet.

Other than that, I might nitpick the placement of the two stereo speakers. They’re located on the top and bottom of the cover screen, which makes them left-side oriented when the Z Fold 8 is unfolded. The speakers get loud enough, but because they’re both on the left in tablet mode, it almost sounds mono coming from one side. To be clear, these are stereo speakers. I get why Samsung might have designed it like this: the speakers fire out of the left and right in tent mode. Maybe put one speaker on each side for a balanced sound when it’s unfolded?

As for the crease… It’s less visible for sure, but hasn’t been completely eliminated. Fresh out of the box, the inner screen is pristine and crease-free. Two weeks in, the crease has deepened with hundreds of folds and I can see it when the screen is off, but it doesn’t warp as much as it did on past Samsung foldables. I almost never notice it when I’m watching videos, gaming, or reading. Besides the reinforced titanium alloy film on top of the screen and the titanium plate underneath it to ensure it stays flatter to the touch over time, Samsung also added an anti-reflective layer to reduce glare, and it really does help. I’ve said it before and I’ll say it again: the crease may never be fully eliminated from folding screens. The best we can hope for may just be making it less visible.

Depending on what you consider the Z Fold 8, either as the sequel to the Z Fold 7 or as a new class of foldables, the cameras will impress or disappoint. If viewed as a Z Fold 7 successor, the 50-megapixel main camera may feel like a downgrade from the previous 200-megapixel shooter. The 50-megapixel ultrawide on the Z Fold 8 will, however, be an upgrade from the Z Fold 7’s 12-megapixel one. You may also be upset it doesn’t have a telephoto lens.

If you want triple rear cameras and more resolution for the main camera, Samsung sells the Z Fold 8 Ultra. I have no complaints with the dual 50-megapixel rear cameras and dual 10-megapixel hole-punch cameras on the Z Fold 8. I don’t think most people will care there’s no telephoto. You still get a 2x zoom that crops in on the 50-megapixel sensor and looks nearly optical-quality to me. This is similar to the virtual 2x “telephoto” that you’ll find on other phones and all recent iPhones that have larger main sensors. The 4x and 10x zooms on the Z Fold 8 are digital, though, and the fuzzier image quality shows.

For everyday photos and videos, the Z Fold 8 cameras are good enough. Image quality looks vibrant and not overly saturated like it used to on Samsung phones and I think the HDR looks less processed compared to iPhone photos. Low-light shots look solid, too. If you’re the type of person who doesn’t want to spend too much or any time editing your photos, the Z Fold 8 photos are more than fine to post directly to social media.

The Z Fold 8 is loaded with a bunch of AI editing features, like “Photo Assist,” which lets you describe an edit with text; “My FanCam,” which lets you motion-track a subject in a video and then crop it for different aspect ratios for posting to social media; and a “Scan” feature that can clean up photos of documents (i.e. sharpen text, flatten and fix the geometry, and remove folded corners or fingers). These can be useful, but there already are apps that exist that do these things. I suppose it’s nice they’re free and built-in.

I also don’t hate any of the new video recording features, like the dual recording mode that lets you record from both the front and rear cameras simultaneously in various layouts (side by side, split top and bottom, and picture in picture) and super steady recording with horizon lock, which keeps the horizon line straight. Again, none are particularly special, but it’s nice that they’re there when you might need them.

It didn’t take long for me to fall in love with the Galaxy Z Fold 8. That’s just not something that happens often anymore. But fall in love with Samsung’s new foldable—I did. The Z Fold 8 is proof that great hardware still matters—and matters more than simply shoving in more AI features.

I like it more than the Z Fold 7 and the Z Fold 8 Ultra, mainly because its 4:3 inner screen makes consuming content a better and more fun experience than swiping on a long bar. One UI 9 is a very polished Android experience, and a feature like Quick Share, which lets you AirDrop files to Apple devices, is a game-changer. Anything that makes an Android phone work with Apple devices is a big plus to me.

There are still some minor things that people will find fault with, like the fact that Samsung has stuck with an IP48 rating for dust and water resistance instead of bumping that up higher to IP68 like Google did with the Pixel 10 Pro Fold or that Samsung didn’t bring back S Pen support. Neither omission makes the Z Fold 8 feel insufficient in my book. I’m not exposing the Z Fold 8 to harsh conditions and I have no attachment to a stylus.

Look, I get it: the Z Fold 8 is still expensive starting at $1,900. I don’t foresee the price of it coming down anytime soon. Samsung’s stuck to around $2,000 for its book-style foldables since the original Galaxy Fold. If you can justify the value of a larger screen experience, the Z Fold 8 is amazing in almost every aspect.

In just two weeks, I watched, gamed, and read more on the Z Fold 8 than I have on any new phone I’ve ever tested. Videos look incredible on the 7.6-inch inner screen; 16:9 videos have minimal letterboxing (black bars) above and below them, and old content like many original anime series in 4:3 aspect ratio fill up the entire screen. I’ve never felt more informed and entertained from my phone.

 © Adriano Contreras / Gizmodo As with the Z Fold 8 Ultra, the Z Fold 8 lets you run three apps in split-screen layouts or four (with a pop-up) on the inner screen. I wouldn’t recommend running more than two apps side by side in landscape orientation. Three apps side by side make each app window very skinny, and one app on one side and two stacked on the other half feel squished. Split-screen apps in vertical orientation just look too long to be useful in most cases. In some split-screen layouts, Samsung’s One UI 9 does let you tap between split-screen apps to have it fill more or most of the screen, but it’s not a function that’s easy to discover. © Adriano Contreras / Gizmodo Performance from the Qualcomm Snapdragon 8 Elite Gen 5 for Galaxy chip is snappy and the 12GB of RAM on my 256GB review unit (you’ll get 16GB if you buy the 1TB model) never chugged when I threw Gemini and Galaxy AI tasks at it. The only thing that occasionally bugs me is that the Z Fold 8 gets toasty even when I’m not doing anything power-hungry. I suspect the super-thin design doesn’t leave much room for adequate thermals; there’s no vapor chamber for cooling like there is on the Galaxy S26 Ultra and iPhone 17 Pro.

 The inner screen has been a joy to use, especially on my 1-hour subway commute to and from work. And instead of reaching for my iPad mini in bed, the Z Fold 8 now fills the role instead. It’s great only having to charge one device. © Adriano Contreras / Gizmodo On the topic of charging, the Z Fold 8’s battery is rock solid, lasting me a full day even with heavy use of the inner screen. That’s not surprising since Samsung added a small percentage of silicon carbon into the 4,800mAh battery, which allows for the larger cell while maintaining a slim size. The 45W fast wired charging, with a compatible charger sold separately (of course), was more than quick enough to give me a recharge (around 0% to 65% in 30 minutes) whenever I was low on power. The Z Fold 8 also supports fast wireless charging at 20W, but I used it less compared to other phones like the iPhone 17 Pro or Pixel 10 Pro because Samsung still refuses to include built-in magnetic charging rings. You, again, need to buy a case with magnets to align the phone effortlessly with a Qi2 charger. © Adriano Contreras / Gizmodo The only blemish, literally, on the larger screen experience is the 10-megapixel hole-punch camera on the inner screen. It can obscure essential parts of a menu, buttons, or text depending on what you’re looking at. For example, in Asphalt Legends, I couldn’t see a menu button that the hole punch covered. The hole punch is most noticeable when reading long blocks of text or black and white manga. It makes more sense to put the camera in the corner since it can’t fit in a bezel like on a regular tablet.

 Other than that, I might nitpick the placement of the two stereo speakers. They’re located on the top and bottom of the cover screen, which makes them left-side oriented when the Z Fold 8 is unfolded. The speakers get loud enough, but because they’re both on the left in tablet mode, it almost sounds mono coming from one side. To be clear, these are stereo speakers. I get why Samsung might have designed it like this: the speakers fire out of the left and right in tent mode. Maybe put one speaker on each side for a balanced sound when it’s unfolded? © Adriano Contreras / Gizmodo As for the crease… It’s less visible for sure, but hasn’t been completely eliminated. Fresh out of the box, the inner screen is pristine and crease-free. Two weeks in, the crease has deepened with hundreds of folds and I can see it when the screen is off, but it doesn’t warp as much as it did on past Samsung foldables. I almost never notice it when I’m watching videos, gaming, or reading. Besides the reinforced titanium alloy film on top of the screen and the titanium plate underneath it to ensure it stays flatter to the touch over time, Samsung also added an anti-reflective layer to reduce glare, and it really does help. I’ve said it before and I’ll say it again: the crease may never be fully eliminated from folding screens. The best we can hope for may just be making it less visible.  © Adriano Contreras / Gizmodo Depending on what you consider the Z Fold 8, either as the sequel to the Z Fold 7 or as a new class of foldables, the cameras will impress or disappoint. If viewed as a Z Fold 7 successor, the 50-megapixel main camera may feel like a downgrade from the previous 200-megapixel shooter. The 50-megapixel ultrawide on the Z Fold 8 will, however, be an upgrade from the Z Fold 7’s 12-megapixel one. You may also be upset it doesn’t have a telephoto lens.

 If you want triple rear cameras and more resolution for the main camera, Samsung sells the Z Fold 8 Ultra. I have no complaints with the dual 50-megapixel rear cameras and dual 10-megapixel hole-punch cameras on the Z Fold 8. I don’t think most people will care there’s no telephoto. You still get a 2x zoom that crops in on the 50-megapixel sensor and looks nearly optical-quality to me. This is similar to the virtual 2x “telephoto” that you’ll find on other phones and all recent iPhones that have larger main sensors. The 4x and 10x zooms on the Z Fold 8 are digital, though, and the fuzzier image quality shows. © Adriano Contreras / Gizmodo For everyday photos and videos, the Z Fold 8 cameras are good enough. Image quality looks vibrant and not overly saturated like it used to on Samsung phones and I think the HDR looks less processed compared to iPhone photos. Low-light shots look solid, too. If you’re the type of person who doesn’t want to spend too much or any time editing your photos, the Z Fold 8 photos are more than fine to post directly to social media.   The Z Fold 8 is loaded with a bunch of AI editing features, like “Photo Assist,” which lets you describe an edit with text; “My FanCam,” which lets you motion-track a subject in a video and then crop it for different aspect ratios for posting to social media; and a “Scan” feature that can clean up photos of documents (i.e. sharpen text, flatten and fix the geometry, and remove folded corners or fingers). These can be useful, but there already are apps that exist that do these things. I suppose it’s nice they’re free and built-in.

 I also don’t hate any of the new video recording features, like the dual recording mode that lets you record from both the front and rear cameras simultaneously in various layouts (side by side, split top and bottom, and picture in picture) and super steady recording with horizon lock, which keeps the horizon line straight. Again, none are particularly special, but it’s nice that they’re there when you might need them.  © Adriano Contreras / Gizmodo It didn’t take long for me to fall in love with the Galaxy Z Fold 8. That’s just not something that happens often anymore. But fall in love with Samsung’s new foldable—I did. The Z Fold 8 is proof that great hardware still matters—and matters more than simply shoving in more AI features.

 I like it more than the Z Fold 7 and the Z Fold 8 Ultra, mainly because its 4:3 inner screen makes consuming content a better and more fun experience than swiping on a long bar. One UI 9 is a very polished Android experience, and a feature like Quick Share, which lets you AirDrop files to Apple devices, is a game-changer. Anything that makes an Android phone work with Apple devices is a big plus to me. There are still some minor things that people will find fault with, like the fact that Samsung has stuck with an IP48 rating for dust and water resistance instead of bumping that up higher to IP68 like Google did with the Pixel 10 Pro Fold or that Samsung didn’t bring back S Pen support. Neither omission makes the Z Fold 8 feel insufficient in my book. I’m not exposing the Z Fold 8 to harsh conditions and I have no attachment to a stylus.

 Look, I get it: the Z Fold 8 is still expensive starting at ,900. I don’t foresee the price of it coming down anytime soon. Samsung’s stuck to around ,000 for its book-style foldables since the original Galaxy Fold. If you can justify the value of a larger screen experience, the Z Fold 8 is amazing in almost every aspect.

Galaxy Z Fold 8 is the best phone (not just foldable) I’ve ever used for consuming content—watching videos, playing mobile games, reading, and yes, even doomscrolling social media—thanks to its 7.6-inch inner screen.

The book-style foldable phone’s novel shape when closed may look strange at first, but I promise you that its shorter and wider footprint (when closed) quickly feels normal after a few days. The whole point of this form factor is to unfold it for its larger tablet-sized screen, and I can assure you that you’ll be doing that often because the experience encourages it more.

More importantly, the Z Fold 8 has fewer of the compromises that held back Samsung’s previous foldable phones. The device is lighter and easier to unfold, the battery is bigger and lasts all day, and Samsung has greatly reduced the crease on the inner screen.

Some apps still might not display correctly on both screens, but even so, I’m declaring the Z Fold 8 a home run. I can’t stop using it.


Samsung Galaxy Z Fold 8

The Galaxy Z Fold 8 is Samsung’s best version of a book-style foldable phone yet, even with its premium price.

The best size comparisons for the Z Fold 8 are a passport or a B7-sized notebook. The foldable measures 4.88 x 3.24 inches when it’s closed. It’s a few hairs thicker than the Z Fold 8 Ultra, but because of the squatter dimensions and lighter weight, the Z Fold 8 doesn’t feel unwieldy. I’m mostly able to reach corner to corner on the 5.5-inch AMOLED cover screen, something I haven’t been able to do on any “regular” (read: 6 to 6.9-inch) bar-style phone in years.

It also fits in my front pants pockets better than expected; I had concerns that the width might be too wide. I guess if you’re already used to the width of an iPhone 17 Pro Max or a Galaxy S26 Ultra, the Z Fold 8’s only slightly wider.

I’m able to reach the power button/fingerprint reader easily with my right thumb. Lefties might struggle since they can’t use their thumb and will have to register their index finger, which might be a little stretch to press the button, like it is for me. The volume rocker is a little high for me; I prefer its lower position on the Z Fold 7/Z Fold 8 Ultra. Typing with two hands on the cover screen is a much easier affair than on narrower phones; I made fewer typos compared to my iPhone. One-handed typing will depend on whether your hand is large enough and your thumb can stretch across the keyboard.

The 10:16 aspect ratio of the cover screen is also not as cramped as it seems. You lose vertical space compared to most regular phones and taller foldables like the Z Fold 8 Ultra, which means apps will show less and you’ll need to scroll more, but that’s mostly a non-issue if you open the phone and rotate it to vertical orientation. I never found myself bothered that I couldn’t see enough on the cover screen. If anything, I appreciated the shorter screen more because I didn’t feel compelled to pull it out as much unless I wanted to unfold it.

Like on the Z Fold 8 Ultra, you can use the Z Fold 8 in “tent” mode. This is great for propping up the device on a plane tray table or if you’re just too lazy to hold it up while in bed. I fly a lot for work, so tent mode is something I find very useful. A Z Fold 8 Ultra feature that you won’t find on the Z Fold 8 is “Flex mode.” On the Z Fold 8 Ultra, you can snap the screen so that it resembles a baby laptop, and some apps, like YouTube, will display the video above the crease and controls below it. I never found much utility for Flex mode on the previous Z Folds and I don’t miss it on the Z Fold 8. If that’s something you care about, get the Z Fold 8 Ultra instead.

Out of all the book-style foldable phones I’ve tested over the past seven years, the Z Fold 8 is the only one that I have unfolded more times than I have not. With each generation of Z Fold, Samsung made the dimensions more like a regular bar-style phone. I heaped praise on the Z Fold 7 for finally ditching the previous skinny, remote-like shape. And even though I considered the Z Fold 7 my favorite Android phone of 2025, I realized that I only used its inner screen maybe less than 50% of the time I pulled it out. With the cover screen being normal-sized, there just wasn’t as much of a need to unfold it for the 8-inch screen.

That hasn’t been the case with the Z Fold 8. Because of the shorter cover screen, I almost always unfold it to use the larger display. Maybe that’s because the Flex Titanium technology helps the hinge spring open better or the beveled aluminum frame makes it easier to unfold without needing fingernails, or both. Whatever the reasons are, it’s easier to see and feel the benefits of the larger size of the inner screen’s 4:3 aspect ratio for most content than on a more square-ish folding screen like the Z Fold 8 Ultra’s. To get roughly the same diagonal screen for widescreen videos on the Z Fold 8 Ultra, you need to rotate it, which is an extra step. It’s a tiny bit of friction that makes the task of quickly unfolding and getting more screen real estate less convenient. When you’re unfolding the phone dozens of times a day, that one extra step adds up.

The foldable measures 4.88 x 3.24 inches when it’s closed. It’s a few hairs thicker than the Z Fold 8 Ultra, but because of the squatter dimensions and lighter weight, the Z Fold 8 doesn’t feel unwieldy. I’m mostly able to reach corner to corner on the 5.5-inch AMOLED cover screen, something I haven’t been able to do on any “regular” (read: 6 to 6.9-inch) bar-style phone in years.

 It also fits in my front pants pockets better than expected; I had concerns that the width might be too wide. I guess if you’re already used to the width of an iPhone 17 Pro Max or a Galaxy S26 Ultra, the Z Fold 8’s only slightly wider. © Adriano Contreras / Gizmodo I’m able to reach the power button/fingerprint reader easily with my right thumb. Lefties might struggle since they can’t use their thumb and will have to register their index finger, which might be a little stretch to press the button, like it is for me. The volume rocker is a little high for me; I prefer its lower position on the Z Fold 7/Z Fold 8 Ultra. Typing with two hands on the cover screen is a much easier affair than on narrower phones; I made fewer typos compared to my iPhone. One-handed typing will depend on whether your hand is large enough and your thumb can stretch across the keyboard.  			 				 			 				 				© Adriano Contreras / Gizmodo 				 			 				 			 				 				© Adriano Contreras / Gizmodo 				 			 				 			 				 				© Adriano Contreras / Gizmodo 				 			 				 			 				 				© Adriano Contreras / Gizmodo 				 		  The 10:16 aspect ratio of the cover screen is also not as cramped as it seems. You lose vertical space compared to most regular phones and taller foldables like the Z Fold 8 Ultra, which means apps will show less and you’ll need to scroll more, but that’s mostly a non-issue if you open the phone and rotate it to vertical orientation. I never found myself bothered that I couldn’t see enough on the cover screen. If anything, I appreciated the shorter screen more because I didn’t feel compelled to pull it out as much unless I wanted to unfold it.

 © Adriano Contreras / Gizmodo Like on the Z Fold 8 Ultra, you can use the Z Fold 8 in “tent” mode. This is great for propping up the device on a plane tray table or if you’re just too lazy to hold it up while in bed. I fly a lot for work, so tent mode is something I find very useful. A Z Fold 8 Ultra feature that you won’t find on the Z Fold 8 is “Flex mode.” On the Z Fold 8 Ultra, you can snap the screen so that it resembles a baby laptop, and some apps, like YouTube, will display the video above the crease and controls below it. I never found much utility for Flex mode on the previous Z Folds and I don’t miss it on the Z Fold 8. If that’s something you care about, get the Z Fold 8 Ultra instead.  © Adriano Contreras / Gizmodo Out of all the book-style foldable phones I’ve tested over the past seven years, the Z Fold 8 is the only one that I have unfolded more times than I have not. With each generation of Z Fold, Samsung made the dimensions more like a regular bar-style phone. I heaped praise on the Z Fold 7 for finally ditching the previous skinny, remote-like shape. And even though I considered the Z Fold 7 my favorite Android phone of 2025, I realized that I only used its inner screen maybe less than 50% of the time I pulled it out. With the cover screen being normal-sized, there just wasn’t as much of a need to unfold it for the 8-inch screen.

 © Adriano Contreras / Gizmodo That hasn’t been the case with the Z Fold 8. Because of the shorter cover screen, I almost always unfold it to use the larger display. Maybe that’s because the Flex Titanium technology helps the hinge spring open better or the beveled aluminum frame makes it easier to unfold without needing fingernails, or both. Whatever the reasons are, it’s easier to see and feel the benefits of the larger size of the inner screen’s 4:3 aspect ratio for most content than on a more square-ish folding screen like the Z Fold 8 Ultra’s. To get roughly the same diagonal screen for widescreen videos on the Z Fold 8 Ultra, you need to rotate it, which is an extra step. It’s a tiny bit of friction that makes the task of quickly unfolding and getting more screen real estate less convenient. When you’re unfolding the phone dozens of times a day, that one extra step adds up. © Adriano Contreras / Gizmodo After two weeks of using the Z Fold 8 and Z Fold 8 Ultra, I’ve concluded that if you watch more videos and game more than you read, the Z Fold 8 is the better foldable since you won’t need to rotate it so much. If you do more reading and split-screen multitasking, the Z Fold 8 Ultra is more suitable since you’ll get more vertical display on both the cover and inner screens without rotating, and you’ll do less scrolling. © Adriano Contreras / Gizmodo I consume a ridiculous amount of content on a daily basis, so I find the 4:3 aspect ratio more versatile for my needs. In just two weeks, I watched, gamed, and read more on the Z Fold 8 than I have on any new phone I’ve ever tested. Videos look incredible on the 7.6-inch inner screen; 16:9 videos have minimal letterboxing (black bars) above and below them, and old content like many original anime series in 4:3 aspect ratio fill up the entire screen. I’ve never felt more informed and entertained from my phone.

 © Adriano Contreras / Gizmodo As with the Z Fold 8 Ultra, the Z Fold 8 lets you run three apps in split-screen layouts or four (with a pop-up) on the inner screen. I wouldn’t recommend running more than two apps side by side in landscape orientation. Three apps side by side make each app window very skinny, and one app on one side and two stacked on the other half feel squished. Split-screen apps in vertical orientation just look too long to be useful in most cases. In some split-screen layouts, Samsung’s One UI 9 does let you tap between split-screen apps to have it fill more or most of the screen, but it’s not a function that’s easy to discover. © Adriano Contreras / Gizmodo Performance from the Qualcomm Snapdragon 8 Elite Gen 5 for Galaxy chip is snappy and the 12GB of RAM on my 256GB review unit (you’ll get 16GB if you buy the 1TB model) never chugged when I threw Gemini and Galaxy AI tasks at it. The only thing that occasionally bugs me is that the Z Fold 8 gets toasty even when I’m not doing anything power-hungry. I suspect the super-thin design doesn’t leave much room for adequate thermals; there’s no vapor chamber for cooling like there is on the Galaxy S26 Ultra and iPhone 17 Pro.

 The inner screen has been a joy to use, especially on my 1-hour subway commute to and from work. And instead of reaching for my iPad mini in bed, the Z Fold 8 now fills the role instead. It’s great only having to charge one device. © Adriano Contreras / Gizmodo On the topic of charging, the Z Fold 8’s battery is rock solid, lasting me a full day even with heavy use of the inner screen. That’s not surprising since Samsung added a small percentage of silicon carbon into the 4,800mAh battery, which allows for the larger cell while maintaining a slim size. The 45W fast wired charging, with a compatible charger sold separately (of course), was more than quick enough to give me a recharge (around 0% to 65% in 30 minutes) whenever I was low on power. The Z Fold 8 also supports fast wireless charging at 20W, but I used it less compared to other phones like the iPhone 17 Pro or Pixel 10 Pro because Samsung still refuses to include built-in magnetic charging rings. You, again, need to buy a case with magnets to align the phone effortlessly with a Qi2 charger. © Adriano Contreras / Gizmodo The only blemish, literally, on the larger screen experience is the 10-megapixel hole-punch camera on the inner screen. It can obscure essential parts of a menu, buttons, or text depending on what you’re looking at. For example, in Asphalt Legends, I couldn’t see a menu button that the hole punch covered. The hole punch is most noticeable when reading long blocks of text or black and white manga. It makes more sense to put the camera in the corner since it can’t fit in a bezel like on a regular tablet.

 Other than that, I might nitpick the placement of the two stereo speakers. They’re located on the top and bottom of the cover screen, which makes them left-side oriented when the Z Fold 8 is unfolded. The speakers get loud enough, but because they’re both on the left in tablet mode, it almost sounds mono coming from one side. To be clear, these are stereo speakers. I get why Samsung might have designed it like this: the speakers fire out of the left and right in tent mode. Maybe put one speaker on each side for a balanced sound when it’s unfolded? © Adriano Contreras / Gizmodo As for the crease… It’s less visible for sure, but hasn’t been completely eliminated. Fresh out of the box, the inner screen is pristine and crease-free. Two weeks in, the crease has deepened with hundreds of folds and I can see it when the screen is off, but it doesn’t warp as much as it did on past Samsung foldables. I almost never notice it when I’m watching videos, gaming, or reading. Besides the reinforced titanium alloy film on top of the screen and the titanium plate underneath it to ensure it stays flatter to the touch over time, Samsung also added an anti-reflective layer to reduce glare, and it really does help. I’ve said it before and I’ll say it again: the crease may never be fully eliminated from folding screens. The best we can hope for may just be making it less visible.  © Adriano Contreras / Gizmodo Depending on what you consider the Z Fold 8, either as the sequel to the Z Fold 7 or as a new class of foldables, the cameras will impress or disappoint. If viewed as a Z Fold 7 successor, the 50-megapixel main camera may feel like a downgrade from the previous 200-megapixel shooter. The 50-megapixel ultrawide on the Z Fold 8 will, however, be an upgrade from the Z Fold 7’s 12-megapixel one. You may also be upset it doesn’t have a telephoto lens.

 If you want triple rear cameras and more resolution for the main camera, Samsung sells the Z Fold 8 Ultra. I have no complaints with the dual 50-megapixel rear cameras and dual 10-megapixel hole-punch cameras on the Z Fold 8. I don’t think most people will care there’s no telephoto. You still get a 2x zoom that crops in on the 50-megapixel sensor and looks nearly optical-quality to me. This is similar to the virtual 2x “telephoto” that you’ll find on other phones and all recent iPhones that have larger main sensors. The 4x and 10x zooms on the Z Fold 8 are digital, though, and the fuzzier image quality shows. © Adriano Contreras / Gizmodo For everyday photos and videos, the Z Fold 8 cameras are good enough. Image quality looks vibrant and not overly saturated like it used to on Samsung phones and I think the HDR looks less processed compared to iPhone photos. Low-light shots look solid, too. If you’re the type of person who doesn’t want to spend too much or any time editing your photos, the Z Fold 8 photos are more than fine to post directly to social media.   The Z Fold 8 is loaded with a bunch of AI editing features, like “Photo Assist,” which lets you describe an edit with text; “My FanCam,” which lets you motion-track a subject in a video and then crop it for different aspect ratios for posting to social media; and a “Scan” feature that can clean up photos of documents (i.e. sharpen text, flatten and fix the geometry, and remove folded corners or fingers). These can be useful, but there already are apps that exist that do these things. I suppose it’s nice they’re free and built-in.

 I also don’t hate any of the new video recording features, like the dual recording mode that lets you record from both the front and rear cameras simultaneously in various layouts (side by side, split top and bottom, and picture in picture) and super steady recording with horizon lock, which keeps the horizon line straight. Again, none are particularly special, but it’s nice that they’re there when you might need them.  © Adriano Contreras / Gizmodo It didn’t take long for me to fall in love with the Galaxy Z Fold 8. That’s just not something that happens often anymore. But fall in love with Samsung’s new foldable—I did. The Z Fold 8 is proof that great hardware still matters—and matters more than simply shoving in more AI features.

 I like it more than the Z Fold 7 and the Z Fold 8 Ultra, mainly because its 4:3 inner screen makes consuming content a better and more fun experience than swiping on a long bar. One UI 9 is a very polished Android experience, and a feature like Quick Share, which lets you AirDrop files to Apple devices, is a game-changer. Anything that makes an Android phone work with Apple devices is a big plus to me. There are still some minor things that people will find fault with, like the fact that Samsung has stuck with an IP48 rating for dust and water resistance instead of bumping that up higher to IP68 like Google did with the Pixel 10 Pro Fold or that Samsung didn’t bring back S Pen support. Neither omission makes the Z Fold 8 feel insufficient in my book. I’m not exposing the Z Fold 8 to harsh conditions and I have no attachment to a stylus.

 Look, I get it: the Z Fold 8 is still expensive starting at ,900. I don’t foresee the price of it coming down anytime soon. Samsung’s stuck to around ,000 for its book-style foldables since the original Galaxy Fold. If you can justify the value of a larger screen experience, the Z Fold 8 is amazing in almost every aspect.

Samsung’s Galaxy Z Fold 8 is the best phone (not just foldable) I’ve ever used for consuming content—watching videos, playing mobile games, reading, and yes, even doomscrolling social media—thanks to its 7.6-inch inner screen.

The book-style foldable phone’s novel shape when closed may look strange at first, but I promise you that its shorter and wider footprint (when closed) quickly feels normal after a few days. The whole point of this form factor is to unfold it for its larger tablet-sized screen, and I can assure you that you’ll be doing that often because the experience encourages it more.

More importantly, the Z Fold 8 has fewer of the compromises that held back Samsung’s previous foldable phones. The device is lighter and easier to unfold, the battery is bigger and lasts all day, and Samsung has greatly reduced the crease on the inner screen.

Some apps still might not display correctly on both screens, but even so, I’m declaring the Z Fold 8 a home run. I can’t stop using it.

I have no complaints with the dual 50-megapixel rear cameras and dual 10-megapixel hole-punch cameras on the Z Fold 8. I don’t think most people will care there’s no telephoto. You still get a 2x zoom that crops in on the 50-megapixel sensor and looks nearly optical-quality to me. This is similar to the virtual 2x “telephoto” that you’ll find on other phones and all recent iPhones that have larger main sensors. The 4x and 10x zooms on the Z Fold 8 are digital, though, and the fuzzier image quality shows.

For everyday photos and videos, the Z Fold 8 cameras are good enough. Image quality looks vibrant and not overly saturated like it used to on Samsung phones and I think the HDR looks less processed compared to iPhone photos. Low-light shots look solid, too. If you’re the type of person who doesn’t want to spend too much or any time editing your photos, the Z Fold 8 photos are more than fine to post directly to social media.

The Z Fold 8 is loaded with a bunch of AI editing features, like “Photo Assist,” which lets you describe an edit with text; “My FanCam,” which lets you motion-track a subject in a video and then crop it for different aspect ratios for posting to social media; and a “Scan” feature that can clean up photos of documents (i.e. sharpen text, flatten and fix the geometry, and remove folded corners or fingers). These can be useful, but there already are apps that exist that do these things. I suppose it’s nice they’re free and built-in.

I also don’t hate any of the new video recording features, like the dual recording mode that lets you record from both the front and rear cameras simultaneously in various layouts (side by side, split top and bottom, and picture in picture) and super steady recording with horizon lock, which keeps the horizon line straight. Again, none are particularly special, but it’s nice that they’re there when you might need them.

Samsung Galaxy Z Fold 8 Review 43

It didn’t take long for me to fall in love with the Galaxy Z Fold 8. That’s just not something that happens often anymore. But fall in love with Samsung’s new foldable—I did. The Z Fold 8 is proof that great hardware still matters—and matters more than simply shoving in more AI features.

I like it more than the Z Fold 7 and the Z Fold 8 Ultra, mainly because its 4:3 inner screen makes consuming content a better and more fun experience than swiping on a long bar. One UI 9 is a very polished Android experience, and a feature like Quick Share, which lets you AirDrop files to Apple devices, is a game-changer. Anything that makes an Android phone work with Apple devices is a big plus to me.

There are still some minor things that people will find fault with, like the fact that Samsung has stuck with an IP48 rating for dust and water resistance instead of bumping that up higher to IP68 like Google did with the Pixel 10 Pro Fold or that Samsung didn’t bring back S Pen support. Neither omission makes the Z Fold 8 feel insufficient in my book. I’m not exposing the Z Fold 8 to harsh conditions and I have no attachment to a stylus.

Look, I get it: the Z Fold 8 is still expensive starting at $1,900. I don’t foresee the price of it coming down anytime soon. Samsung’s stuck to around $2,000 for its book-style foldables since the original Galaxy Fold. If you can justify the value of a larger screen experience, the Z Fold 8 is amazing in almost every aspect.

The watch’s insecurity and the spying it enabled might be expected given the gadget’s pedigree: It’s sold by an obscure company called CJC, costs less than $30, and was made by an equally obscure manufacturer, YiQingTeng Electronics, in Shenzhen, China. More troubling, perhaps, is that the online platform it’s built on—and the one that allowed Stykas and Solferini to so thoroughly hack it—is used by dozens of other brands of smartwatch, many of which have likely been left vulnerable to the same forms of digital stalking.

At the Black Hat cybersecurity conference today, Stykas and Solferini plan to present their findings from analyzing the supply chain and security of more than 70 GPS-enabled watches and car accessories. They found that more than 30 of those geolocation devices use the technology and backend servers of YiQingTeng, also identified by the brand name Wonlex, the name of a partner firm Shenzhen 3G Electronics, or their associated app, SETracker. Another 30-plus brands of tracking devices for cars and kids are all run on another Shenzhen-based platform known as NewGPS2012.

Combined with another major GPS platform known as SinoTrack that sells car trackers and smartwatches, the two researchers found that tens of millions of GPS tracker gadgets came from just three supply chains. All three, the researchers found in their analysis, had significant security flaws—in some cases as simple as a lack of authentication that allowed anyone to access any device—leaving children’s watches vulnerable to tracking by a hacker, location disabling and spoofing, interception and spoofing of text and audio messages sent to them, replacement of emergency contacts with ones a hacker chose, silent audio eavesdropping, as well as photo and video capture for camera-enabled devices. (Once the GPS started working on the smartwatch WIRED tested, the hackers showed that feature, too, could be hijacked to follow the wearer’s every move.)

For some GPS-enabled car accessories, the researchers found they could similarly track the devices’ locations or spoof messages to them that could potentially unlock or disable cars, though the researchers didn’t go so far as to test this out on actual vehicles. They also say they found server-side vulnerabilities that exposed consumer information, would have allowed them to execute their own code on the servers, or even in one case appeared to show that someone else had already gained unauthorized access to the system’s backend.

“Millions of kids are being exposed and vulnerable to exploitation. It’s just catastrophic. It’s really low-hanging fruit for a lot of bad actors,” Stykas says. “Your criminal mind is the only limitation in exploiting those devices.”

The Watches Watching Your Kids

The researchers say they’ve been warning the companies behind all three Shenzhen-based GPS platforms about their vulnerabilities for months. When WIRED reached a representative of SETracker, the person initially claimed in an email that “the issues you mentioned have been resolved long before,” adding that “we attach great importance to the security of Setracker and keep strengthening its security continuously.” When WIRED pointed out that researchers had been able to hack a smartwatch running on SETracker just this week, the person repeated their claim that the issues had been fixed, then asked for evidence of the exploitation, which WIRED provided.

Only today, hours before the researchers’ talk at Black Hat, did the researchers find that their hacking techniques against SETracker’s platform have stopped working—though they’re still not sure if the flaws they found are fully fixed.

Sinotrack and the NewGPS2012 platform didn’t respond to WIRED’s requests for comment, and the researchers say their hacking techniques against those systems still appear to work.

For more than a decade, cybersecurity experts and privacy advocates have warned that cheap, GPS-enabled children’s smartwatches and aftermarket vehicle accessories are riddled with security vulnerabilities that leave kids and drivers susceptible to hacking and tracking. But the sheer number of different brands and models of those devices has often made identifying the truly insecure gadgets feel nearly impossible for consumers.
