The Samsung Galaxy Z Fold 4 is here; it’s the Korean tech giant’s newest large-format folding phone, replacing last year’s Z Fold 3 – although it’s certainly an iterative upgrade in most departments.
Launched alongside the Galaxy Z Flip 4, the Z Fold is Samsung’s newest addition to its legacy line of book-style folders, which first appeared in 2019.
This lineup has proven to be the popular model for anyone who needs big screens and lots of power, and the Fold models are great for work and multitasking – although the Flip has historically outperformed the Fold by a considerable margin.
Could this change with the Samsung Galaxy Z Fold 4? We’ll have to see for our full review, which we’re currently working on. But in the meantime, here’s everything you need to know about the device.
Samsung Galaxy Z Fold 4: price and availability
The Samsung Galaxy Z Fold 4 starts at $1,799.99 / £1,649 / AU$2,499, which matches the Z Fold 3’s starting cost of $1,799 / £1,599 / AU$2,499 in most regions… be in the UK. Sorry, Brits.
That’s for 256GB – there’s also a 512GB version for $1,919.99 / £1,769 / AU$2,699 and a 1TB model for $2,159.99 / £2,019 / AU$2,999. So it’s certainly an expensive phone – not one to buy if you’re not committed to the foldable future.
The phone will go on sale August 26, alongside the Z Flip 4, though you can pre-order it from August 10 in most places (but a day later in Australia).
Samsung Galaxy Z Fold 4: design and display
The Samsung Galaxy Z Fold 4 retains the ‘book-style’ folding form factor of its predecessor – that means it starts out as a regular ‘candy bar’ phone, but you can unfold it to create a larger screen.
According to Samsung, this is its slimmest Fold to date, with a weight of 263g and a few millimeters lost in the height and width of the device. This is partly due to the use of ultra-thin glass, which is strong but, as the name suggests, thin.
This external screen is 6.2 inches diagonally, with a resolution of 2316 x 904, so it’s quite long and thin. The internal screen is much larger at 7.6 inches, and its 2176 x 1812 resolution means that it is much more square than the other screen.
Those dimensions mirror those of the Z Fold 3, and overall, this new phone doesn’t bring a redesign over the older model – just tweaks. On the back, it has an elegant shine broken by a camera bump (we’ll talk about that in a moment).
The Fold comes in green, beige and black, but the S22 Ultra’s range of vibrant tones doesn’t appear, apparently.
Samsung Galaxy Z Fold 4: Cameras and battery life
It’s in the camera department that we see the Samsung Galaxy Z Fold 4 bring more updates over its predecessor.
For starters, there’s a 50MP main camera, up from 12MP on the older model, and while we don’t know about the sensor here, we rarely see bad 50MP snappers on phones. There’s also a 3x optical zoom lens, up from 2x on the Fold 3, although the sensor is actually a 10MP downgrade rather than 12MP.
Plus there’s a 12MP ultra-wide, but it’s the same as last year. The front cameras are also the same as before: 10MP for the external screen and 4MP for the internal one. The latter is a UDC, or Under-Display Camera, and it sits underneath the screen so you can’t see it… however, the snapper wasn’t great on the Z Fold 3, and Samsung hasn’t mentioned any improvements here.
These cameras will be enhanced with all the usual Samsung software paraphernalia – modes like Single Take, Food and others are useful as they utilize AI to help you take the best snap possible.
The battery might not be that impressive, as at 4,400mAh, it’s quite small. In comparison, the S22 Ultra has a bigger power pack despite having only one screen. Maybe some optimizations can make the phone last longer than we expect, and we’ll have to see.
Charging isn’t fast either, at 25W, and at that speed it’ll likely take over an hour to power the device to its fullest. Samsung says the phone will power up to 50% in 30 minutes.
Samsung Galaxy Z Fold 4: performance and software
With a Snapdragon 8 Plus Gen 1 chipset, the Galaxy Z Fold 4 is an extremely powerful phone, surpassing all other Android phones (except others that use the same chip, of course).
However, we found that the Snapdragon 8-series chipsets have an overheating issue, so be warned if you’re a big mobile gamer.
The chip is paired with 12GB of RAM, which should make the tablet fast for multitasking purposes (as you’d expect, for a full-size phone).
Samsung uses Android for its phones but overlays the One UI skin – it does the same for the Fold, but uses Android 12L.
Android 12L is a version of Android 12 designed for larger screens, with a redesigned notification shade, new lock screen, easier multitasking, and improved app designs to work better on tablets and foldables.
A UI offers a design makeover and also brings many Samsung apps like App Gallery, Samsung Pay and more.
