Gapgate is worse than it sounds: a hinge gap on an IP68 foldable

How much is an IP68 rating worth if you can see the hinge through the side of the phone? On a $1,999 foldable, that is no longer a hypothetical. It is the question Apple has to answer.

Owners of the iPhone Duo are reporting what is being called "Gapgate". As Clubic reports, some of them can see the hinge mechanism through an open gap between the back of the device and its edge. It follows "Crackgate", the inner-screen cracks that Apple acknowledged as affecting only a small number of units. Apple has told those customers to contact AppleCare for a replacement.

A gap on a sealed phone is a different kind of problem

Cracks are about a part failing. A gap is about a design promise failing. The iPhone Duo is rated IP68, which Tom's Guide describes as handling submersion in up to six meters of water for up to 30 minutes. A seal is only as good as the joint it sits in. Hinges are the hardest joint on a foldable, because they move thousands of times.

We should be careful here. The documentation we have does not show a single lab test proving water gets in through the gap. The reports that exist are mostly user sightings and secondhand claims. One of them, which we can't verify, says the JerryRigEverything channel found dust inside the hinge despite the rating. Another outlet says some units were "improperly assembled". Both would point to a manufacturing problem, not necessarily a design one. But it is also exactly the kind of claim Apple could settle in a day.

The two defects probably share a root cause

It would be convenient to treat the gap and the cracks as separate bugs. We doubt that. iFixit's teardown, as iPhoneSoft reports, suggested a faulty hinge could be involved in the cracks, and Apple has not confirmed that. The same hinge now appears in a second complaint. That is a pattern, even if it is only a suspicion. Our reading is that the first production run of a very complicated mechanism is showing tolerance problems. That would be understandable for a first-generation product. It would be less understandable at this price.

Apple's handling so far is also telling. An internal memo told Apple Stores and authorized service centers to examine affected units and then repair or replace them under the usual procedures. Apple has said there is no recall, and no public repair program has been announced. Calling it a small number of devices is fine, but a memo to the whole repair network suggests, in our view, that this is more than a rounding error. Samsung has already turned the cracks into an Instagram ad in Canada, as iPhoneSoft notes. Rivals will probably use the gap too.

What Apple should say, and what buyers should do

Apple should answer three questions publicly:

• Does the IP68 rating still hold on a unit with a visible gap?
• Is water damage through the hinge covered by the warranty?
• Will a gap be treated like the cracks, meaning replaced through AppleCare?

Without that, owners are guessing. Anyone who has to prove a seal failed after the fact is in a weak position.

For buyers, our advice is simple. Inspect the closed phone's edges carefully the day it arrives, and photograph any gap. Contact Apple right away if you find one, and keep the phone away from pools and beaches until you get an answer. If you are still waiting on an order, there is no rush. Delivery times are already stretching into 2027, according to Tom's Guide, so waiting costs you nothing.

Our verdict is that Gapgate may be minor for most units and serious for a few. But "the rating probably still works" is not something you can sell for $1,999. Apple built its reputation on details it controls. This time it should explain the hinge before others do.
