Samsung's next Unpacked event is this week, and it's expected that the Galaxy Z Fold 4 could be revealed. Rumors and reports suggest the successor to last year's Galaxy Z Fold 3 will have a sleeker design and better cameras that are on par with the Galaxy S22's, among other improvements.

Samsung hasn't made any announcements about what's in store for the Galaxy Z Fold 4. But to encourage people to reserve their phones early, from July 19 until Aug. 10, Samsung is offering an extensive list of discounts based on different bundles, from a maximum of $200 off for those reserving a Galaxy phone, watch and buds down to a minimum of $30 off for reserving just Galaxy Buds. While this could be a hint at what's coming at Unpacked -- potentially implying that new versions of the Z Flip, Galaxy Watch and Galaxy Buds may be on the way -- the savings could also apply to older Galaxy Watch or Galaxy Buds models.

Here's what we've heard about the Galaxy Fold 4 so far, in terms of price, new features and possible specs. We'll be updating this story as new information becomes available.

Possible Amazon leak reports lots of Galaxy Z Fold 4 details

Samsung's next foldable phone might have had an accidental reveal on Amazon's Netherlands store. An Amazon listing for the Galaxy Z Fold 4, reported Friday by 9to5Google, includes mention of a 6.2-inch outer display, a 7.6-inch inner display, a 120Hz refresh rate on both screens and a new S Pen case.

According to the listing, the phone's inner screen displays a taskbar similar to what's seen on Android tablets that includes app icons and other controls. The model seen in the listing also includes 512GB of storage and 12GB of memory.

Design: Galaxy Z Fold 4 may not have an S Pen slot, but perhaps a new hinge

There's no doubt in our minds that the Galaxy Fold lineup represents a remarkable showcase of technology and innovation. But there's just one thing: Samsung's top-of-the-line foldable isn't inherently practical like, say, the Galaxy Z Flip 3 or even the Galaxy Note series. For example, there was no slot for the S Pen in the Galaxy Fold 3, and based on rumors, it's unclear if a Galaxy Z Fold 4 will have one either.

Twitter leaker Ice Universe, known for publishing Samsung leaks, said in April that the Galaxy Z Fold 4 wouldn't have an S Pen storage slot. But Korean news outlet The Elec previously reported that the Galaxy Z Fold 4 would be Samsung's first foldable to include a designated S Pen holster. 

We're crossing our fingers that the latter is true. Even better, it would be great if the Z Fold 4 supported a way to magnetically attach the S Pen to the phone's hinge, similar to how an Apple Pencil can stick to an iPad Pro. 

Speaking of hinges, the next Galaxy Z Fold may sport a single hinge design instead of the double hinge seen on previous Samsung foldable phones. That is, according to leaker @TheGalox, who 9to5Google says has a decent track record. Ice Universe also reported similar findings more recently, saying the Z Fold 4's hinge would indeed be slimmer. This change would likely result in a thinner and lighter overall design compared with the Z Fold 3. 

Expect the screens to remain the same size as those found on the Z Fold 3. Ice Universe says the Galaxy Z Fold 4 will have a 7.6-inch interior display and a 6.2-inch outer screen (identical specs to the reported Amazon leak), each of which will reportedly have a 120Hz refresh rate. 

The Galaxy Fold 4 might rock a double-sided fingerprint reader

Samsung introduced a fingerprint sensor to its foldable phone via the Galaxy Fold 3, where it's located on the right side of the handset. Accessible whether the device is folded shut or opened up, it also doubles as a power button. 

However, that fingerprint reader may be on the move, according to Dutch publication Lets Go Digital, and may be placed under the screen instead. To back up the assertion, Lets Go referred to a patent Samsung filed in March last year, saying the company plans to incorporate the fingerprint reader in such a way that it can be used as a double-sided fingerprint sensor. It would work on the cover screen (when the handset is folded shut), as well as when the device is unfurled to a tablet-size device. On the cover screen, the fingerprint scanner would reportedly be used from the center bottom of the display. When the phone's unfolded, it would be on the center bottom of the left screen, the report says. 

Cameras: What to expect for the Galaxy Z Fold 4 

The Galaxy Z Fold 4 could be getting a Galaxy S22-like upgrade. According to Dutch blog GalaxyClub, Samsung may adopt the Galaxy S22's 10 megapixel telephoto sensor with 3x optical zoom for the upcoming foldable. If this rumor becomes a reality, the Fold 4 will have a better zoom range than previous models of the device. 

The leak from Ice Universe also suggests the Galaxy Z Fold 4 will inherit some characteristics from the Galaxy S22's camera. That means a 50-megapixel main camera, 12-megapixel ultrawide camera and 10-megapixel telephoto camera might be in store. As for the selfie camera, Ice Universe reports that the Galaxy Z Fold 4 will have a 4-megapixel inner camera and a 10-megapixel outer camera just like its predecessor.

Samsung's Fold 4 may also have under-display cameras on cover and interior screens. The Galaxy Fold 3 also debuted an under-display camera to Samsung's lineup of foldables. It's located beneath the large internal display, and is one of five cameras on the device. According to rumors, the Galaxy Fold 4 will also rely on five cameras, but there'll be two under-display cameras this time around, at least according to one Korean leaker, who goes by the handle yeux1122. 

This is another rumor I hope is inaccurate (unless Samsung drastically improves its tech) since the Galaxy Fold 3's under-display camera was its weakest link, camera-wise. According to a review of the Galaxy Fold 3 by CNET's Patrick Holland, indoor selfies taken with it looked "highly processed," and even outdoor snaps in good lighting didn't look much better.

Processor: Galaxy Z Fold 4 might have Qualcomm's more powerful new chip

Samsung's next foldable phone could run on Qualcomm's newly announced Snapdragon 8 Plus Gen 1 processor, according to Ice Universe. The Snapdragon 8 Plus Gen 1 is a faster and more power efficient version of the standard Snapdragon 8 Gen 1, which is found in the Galaxy S22 series. It makes sense that a high-end phone like the Galaxy Z Fold 4 would have a more powerful chip. But Samsung wasn't listed among the brands that'll be adopting the new chip that Qualcomm mentioned when announcing the processor. 

Otherwise, Ice Universe's leak indicates the Galaxy Z Fold 4 will have a lot in common with the Galaxy Z Fold 3. The new phone will reportedly have 12GB of RAM, options for 256GB or 512GB of storage, a 4,400 mAh battery and 25-watt fast charging. 

Price: Galaxy Z Fold 4 price may shift

The Galaxy Z Fold 4 might have a different price than last year's Galaxy Z Fold 3. According to prominent phone leaker Steve Hemmerstoffer, known on Twitter as OnLeaks, the Galaxy Z Fold 4 might start at 1,799 euro for its 256GB model and 1,919 euro for its 512GB model. That base price is higher than the Galaxy Z Fold 3, which launched at 1,695 euro. Pricing will likely vary based on territories, but the Galaxy Z Fold 3's US launch price was $1,800 by comparison. 

This contrasts with a projection from April by analyst Ross Young, CEO of Display Supply Chain Consultants, who then reported that the Galaxy Z Fold 4 and Z Flip 4 could see a price drop.

Though the Fold 3 is the most expensive phone Samsung has released in 2021, it still got a welcome price drop compared with the previous Fold 2 and the original 2019 Fold. The Fold 3 comes in at a starting price of $1,800 in the US, which is a welcome $200 price cut from the Fold 2's launch price. In the UK the Z Fold 3 starts at £1,599 for the 256GB variant, while in Australia it's AU$2,499. The clamshell Z Flip 3 meanwhile saw its launch price slashed by nearly $400.
