Short answer, as of September 2026: nobody knows, because Apple has not released a foldable iPhone. There is no model on Apple's iPhone lineup, no published dimensions, and no hardware for anyone to test. Any site telling you a housing already fits one is describing a rumor, not a fit.
That is simply where things stand on the day this was written. Foldables from other makers have been shipping for years, so the question is a fair one, and it has a useful version: if a foldable iPhone arrives, what would DIVEVOLK actually have to check before putting it on the SeaTouch 6 Pro compatibility list? The honest answer involves more than a tape measure, and it is worth knowing before you spend money on either device.
What we can confirm today
The SeaTouch 6 Pro accepts phones up to 180.0 by 82.5 by 11.2 mm with a camera bump as tall as 17 mm, in an internal cavity widened to 18 mm from 15 mm on the previous generation. Every phone in that list today is a single rigid slab. The envelope was designed around one flat back, one flat screen, one camera cluster in a known corner, and a body that does not change shape while it is in your hands.
A folding phone breaks four of those five assumptions at once, which is why it cannot be assessed by comparing numbers to that envelope. Fitting a folded phone into a cavity is easy. Making the housing work is the part that needs testing.
Which state is the housing for?
A foldable is two devices sharing a chassis. Folded, it is thick, narrow and usually has an outer cover display with its own resolution and its own camera behavior. Unfolded, it is thin, wide and has a large inner screen with a crease down the middle. Android's own developer documentation on foldables treats folded and unfolded as separate device postures for exactly this reason: apps behave differently in each.
A housing has to commit to one. Build for folded and you get a workable thickness but you are shooting through the cover display, with whatever camera set that state exposes. Build for unfolded and the width almost certainly exceeds 82.5 mm, so it is a different housing, not an adapter change. Either way the answer has to be stated as a state, and a compatibility line that just says "fits" without saying folded or unfolded is not an answer.
The hinge is a moving part inside a pressure vessel
At 40 meters, ambient pressure is about five times what it is at the surface. A rigid phone in a rigid cradle simply sits there. A hinged phone has a mechanism that can be loaded, and the cradle has to be designed so that nothing presses the two halves toward each other or apart while the housing flexes under load.
That means the phone support has to hold both halves independently, with the hinge itself carrying nothing. It also means the phone must not be able to change posture in the housing, because there is no way to correct it mid-dive. Testing this is not a one-off dry fit; it is repeated closure cycles, insertion and removal, and a pressure profile with the phone in place looking for any load path that reaches the hinge.
Membrane contact needs a flat, supported screen
The DIVEVOLK membrane works by passing a fingertip's pressure through a flexible film to the phone's own capacitive screen. That transfer depends on the screen sitting flat and firmly backed. A folding inner display has a crease, and it is supported by a hinge assembly rather than a continuous rigid frame.
Two questions follow, and neither can be answered from a spec sheet. Does a touch land accurately along the crease and near the hinge line, or does the screen deflect and swallow it? And does a display designed to bend tolerate repeated localized pressure over hundreds of dives? The sixth-generation film is rated to 150,000 swipe cycles on DIVEVOLK's bench standard, but that standard was written against flat glass. It would need re-running against a folding panel before anyone quoted the number for one.
Screen protectors add a wrinkle here too. With the sixth-generation membrane, newer flat phones can keep their protector on inside the housing. Foldable inner displays usually ship with a factory-applied film that the maker warns against removing, which is a different material in a different place, and it would have to be tested as part of the configuration rather than assumed away.
Cameras, and where they end up
The SeaTouch 6 Pro has a single lens window and an integrated dome port slot, and the second-generation Dome Lens covers the main and ultra-wide cameras together so you can switch lenses underwater without repositioning anything. That works because those cameras sit close together in a known corner.
On a foldable, the camera cluster position moves relative to the outer edges depending on which half you are looking at, and the cover camera and inner camera are frequently different hardware. Before any lens or filter claim could be made, DIVEVOLK would need the final camera coordinates, the actual bump height, and confirmation of which cameras are available in the state the housing is built for. Nothing from the wet lens range can be promised until then.
Heat, radios, and the buttons you cannot reach
Sealed housings trap heat, and phones throttle. Apple documents its own temperature management behavior for current iPhones: sustained recording in warm conditions can dim the display, slow charging or stop the camera. A foldable has two display panels and a different internal layout, so its thermal behavior inside a housing is its own test, run at the video resolution divers actually use.
Radio behavior needs its own check as well. Cellular and GPS pass through the SeaTouch 6 Pro's engineering-plastic body at the surface, which is what lets a diver call for help without opening the case. Whether that holds with a different antenna layout is a measurement, not an assumption.
And one thing that would not change at all: the SeaTouch 6 Pro is button-free, and any phone sealed inside it loses access to its physical volume, power and side buttons. Whatever a foldable iPhone's hardware controls turned out to be, they would be unreachable underwater, and any native camera mode that works by disabling the touchscreen and moving the shutter to the volume keys would have to be left switched off. The touchscreen is the only input path a SeaTouch has. A tactile shutter comes from the DIVEVOLK Bluetooth external shutter, which the SeaTouch 6 Pro mounts on either side.
It is also worth remembering that a phone's own IP rating never adds to a housing's. Apple's water resistance guidance describes controlled lab conditions and non-permanent resistance, and hinged devices have historically been the harder case for ingress protection. The housing is what goes to 60 meters.
What happens the week a phone actually launches
None of the above is theoretical. It is the same sequence DIVEVOLK runs for every new phone, compressed into the days after a launch: obtain a retail unit in the region it ships, measure the production sample rather than the press-kit drawing, design or select the phone support, dry fit without force, run a fixed set of camera and touch tasks through the membrane, then a pressure test, then a supervised water dive, and only then a dated line on the compatibility list naming the exact model and configuration.
A foldable adds state-specific repeats of most of those steps plus the hinge load work, so it takes longer than a slab phone, not less. We wrote about how that process handles a phone Apple has announced in our iPhone 18 Pro compatibility status piece, and about how rumors get weighed before a launch in the rumored iPhone Ultra article.
What to do while you wait
Buy a housing for the phone you own, not the phone you might buy. The SeaTouch 6 Pro's compatibility list already runs from the iPhone 6 through the iPhone 17 Pro Max and across the Android imaging flagships, and the housing outlives most phone upgrades because the phone support is what changes, not the shell.
If a foldable is your only phone today, ask technical support with the exact model name before ordering anything. They will tell you what is on the list and what is not, which is more useful than a size comparison you run yourself. And if you want to be told the moment a verdict exists rather than when a rumor does, contact us and ask to be flagged for that model.
When a foldable iPhone exists, this page gets a dated answer with the model name in it. Until then, the useful decision is which housing fits the phone in your pocket, and the housing selection guide is where to start.
