Samsung has been one of the leading lights in the recent arrival of smartphones with foldable displays.

At the moment it has two offerings in this category: the Galaxy Z Flip which - as the name suggests - is like a classic flip phone. The Galaxy Z Fold has a vertical hinge, where you open it up like a book.

New rumours have begun appearing regarding improvements we may see to the latter. Here’s everything we know so far about the Samsung Galaxy Z Fold 4.

When will the Samsung Galaxy Z Fold 4 be released?

Samsung hasn't admitted the Galaxy Z Fold 4 even exists, even though rumours seem to suggest that it’s very much a reality.

Because of this, we don’t have any official details regarding the device, and that includes its release date.

But, we have seen reports that the new Fold will follow the pattern of earlier models. This makes it likely that we should see the Galaxy Z Fold 4 around the end of August or the start of September 2022 - almost certainly alongside the Galaxy Z Flip 4.

To illustrate this, here’s how the previous models lined up:

How much will the Samsung Galaxy Z Fold 4 cost?

Pricing has been somewhat moveable when it comes to foldables. Most started out at eye-watering amounts, obviously due to the incredibly innovative technology needed to make a folding screen possible.

As the techniques have been improved and processes refined, this has seen a drop in the end-cost for consumers. Of course, these are still premium devices, and come with prices commensurate to this status.

To see what the Galaxy Z Fold 4 might cost, here’s a breakdown of the models that came before:

  • Samsung Galaxy Z Fold – £1,900/€1,949/$1,980
  • Samsung Galaxy Z Fold 2 – £1,799/€1,899/$1,999
  • Samsung Galaxy Z Fold 3 – £1,599/€1,799/$1,799

As you can see, there’s a downward trend, and that's expected to continue. Industry expert Ross Young thinks so at least, reporting that Samsung doubled its July production of Z Fold 4 and Z Flip 4 units (relative to production of the third-gen models in 2021), which he believes means we "Might see a price cut."

Will it be the Z Fold 4 or just the Fold 4?

One interesting wrinkle this year is that Samsung may be changing its naming convention. The company has taken the 'Z' out of the names of its foldables in select markets without any explanation - though some speculate that it may have been in response to Russia's invasion of Ukraine, with the 'Z' symbol sometimes used by Russia's armed forces.

In any case, it's opened speculation that the company may drop the 'Z' entirely, leaving its next-gen foldable simple called the Galaxy Fold 4. That would be cleaner and simpler, and in our eyes certainly a welcome change, but for now there's little concrete evidence that any branding change is on the way worldwide.

What about the Samsung Galaxy Z Fold 4 specs?

You’ve probably already surmised that no-one outside of Samsung yet knows for sure the tech specs of the Fold 4. But there have been some rumours appearing that throw light on what the new foldable may contain when it arrives, hopefully, in the second half of next year.

Core specs

In terms of the chipset, there’s a good chance that the Snapdragon 8 Gen 1 processor will make it to the Fold 4, though both TheGalox and Ice Universe actually predict it will instead adopt the rumoured 8 Gen 1+, likely to be announced later this year.

Displays

As for the folding displays, a report from TheElec adds small notes on the phone's displays, which are apparently going to stay about the same size at least: 7.56in for the main display and 6.19in for the outer screen - each within 0.01in of the corresponding Z Fold 3 screens. That's been backed up by display expert Ross Young, who specifically repeats the prediction of a 6.19in outer display while comparing the Fold 4 to the upcoming Pixel foldable.

There may be a subtler improvement here though. Both TheGalox and yeux1122 report that the Z Fold 4 will feature improved Ultra Thin Glass (UTG) on the folding screen. This will be "a big improvement" according to Galox, and have "improved hardness and quality" according to yeux1122, though the two disagree on the potential branding - either 'Armor UTG' or 'Super UTG'.

Design

yeux1122 has separately reported on a range of expected changes for the upcoming model, which include work on improving the hinge mechanism on the new Fold 4, which as you can imagine is a crucial feature of the design. Depending on how the refinements go, this is also rumoured to result in a lighter chassis.

This is good news as in our Samsung Galaxy Z Fold 3 review we pointed out that while the design had improved from the earlier versions, it was still a heavy and cumbersome device, so losing a few grams could go a long way to addressing that concern.

The above report from TheElec also says that Samsung is working on incorporating an S Pen slot into the chassis of the Z Fold 4, just as it has in the Galaxy S22 Ultra this year. Presumably that would also mean the stylus will come bundled with the phone by default.

Others suggest that Samsung has moved on from this idea though. IceUniverse has tweeted that the phone "will not have built-in S Pen," but that instead it will be "a little smaller and thinner." It sounds like Samsung has struggled to incorporate the stylus without making the phone as a whole too bulky, so it may remain an optional add-on for now.

Rumours do state that Samsung will add improved dust-proofing, something that again seems very important when you consider the grinding that grit and sand can bring to that hinge mechanism.

Cameras

Another criticism we had of the Fold 3 was the poor under-display camera. Yes, it does mean you don’t have to have a punch-hole aperture or a notch, but that’s not much use if the results aren’t up to snuff.

That means we're a little concerned by one rumour that the under-display camera will not only be on the inside, as it was with the Fold 3, but also make an appearance on the external display as well. We hope that Samsung has mastered this technique, because the results on the Fold 3 were pretty terrible.

Still, leaks do agree that Samsung will be working to improve the camera experience elsewhere in any case.

GSMArena also alludes to an improved camera experience on the Galaxy Z Fold 4, but there are no specifics on how it would compare to the existing array of 12Mp f/1.8 main camera w/ OIS, 12Mp f/2.2 ultrawide camera, and 12Mp f/2.4 telephoto camera w/ OIS + 2x optical zoom.

GalaxyClub has a little more detail, reporting that the Z Fold 4 will adopt the 10Mp 3x optical zoom sensor found on the S22 series. That's a slight resolution downgrade from the Z Fold 3's telephoto, but with a higher zoom level and other enhancements it is otherwise an upgrade. The site also reports that the phone will stick with a 10Mp cover selfie camera.

The 3x zoom sensor might not be the only one borrowed from the S22 line. Since then leaker Dohyun Kim has predicted that the Fold 4 will adopt a 108Mp main camera, prompting fellow leaker Chun to chime in that in fact that whole rear camera array will be the same as that found on the S22 Ultra - though warning that this might be with the exception of that phone's periscope camera, which might be dropped along the way.

If so, that would mean a 108Mp main camera with the 1/1.33in ISOCELL HM3 sensor, along with the 10Mp 3x zoom mentioned above, and a 12Mp ultrawide.

Battery

The battery doesn’t seem to be getting any kind of boost in the Fold 4, which is a shame. GalaxyClub dug through a SafetyKorea battery certification to discover that the two cells in the Fold 4 (one for each side of the hinge) will have a combined rated capacity of 4270mAh - almost identical to the 4275mAh rated capacity of the Fold 3. That means that the advertised typical capacity will almost certainly be the same 4400mAh as the previous phone.
