TL;DR: Since Apple’s first foldable went on sale on October 23, 2026, a small but growing number of owners have reported the iPhone Duo’s inner screen cracking along the hinge, often with a loud crack while opening or closing and a strip of stuck white pixels running across one half. Nobody has confirmed the cause. iFixit’s teardown traces the damage to a spot where several hinge parts meet under the display, and a YouTuber who took apart his own broken unit found a thin hinge link that had snapped. Apple has not commented publicly as of October 26. It has no software fix for hinge problems; its own guide ends with a new inner display. Owners who bought from Apple have mostly been given a replacement on the spot. If yours cracks, stop folding it, back it up and go to Apple inside the 14-day return window if you can. Out of warranty, an inner screen costs $999 (£999). With AppleCare+ it’s $99 (£79).
Last updated: October 26, 2026. By Veer. Facts checked against Apple’s hinge troubleshooting guide, AppleCare+ fees (UK), US return policy and warranty page, plus iFixit’s teardown and reporting by MacRumors, 9to5Mac, AppleInsider and The Verge. This is a researched explainer. TrustLoud has not handled an iPhone Duo.
What is happening with iPhone Duo screens?
Some iPhone Duo inner displays are failing in the same place: a crack down the center of the fold and a horizontal band of glowing white pixels across one side. The reports started on launch day and picked up the nickname “Crackgate” on forums and social media.
The details owners describe are consistent:
- It happens fast. An owner in Australia told MacRumors his phone broke after about six hours and “probably fewer than 20” openings. He said he felt something catch under the screen, then heard “an audible crack”. 9to5Mac says a couple of people reported it happening during initial setup.
- It looks the same every time. 9to5Mac describes the screen cracking “down the center line of the hinge,” followed by a horizontal block of pixels “stuck glowing white.”
- Some owners felt the hinge tighten first. One Reddit user quoted by iFixit wrote: “Maybe folded it 4 times, hinge got tight and then made a loud pop when I pushed past it.”
- The outside often looks fine. The Australian owner said there were no marks on the inner screen or the hinge before it broke.
Some early photos came from demo units in China, where the phone launched hours before the US. MacRumors notes that the backstory of those images is unknown and user damage can’t be ruled out in every case.
How many iPhone Duos are affected?
Nobody outside Apple knows, and the numbers reported so far are small. These are the only concrete counts we could find:
| Source | What they counted | When |
|---|---|---|
| 9to5Mac | “About ten unique instances,” many on the iPhone Duo subreddit | October 25 |
| AppleInsider | Genius Bar contacts at 7 US Apple Stores (4 flagships): none on October 24, one case by late October 25 | October 24–25 |
| MacRumors | Photos on Reddit and the MacRumors forums; “it isn’t known how widespread the issue is” | October 23 |
Apple hasn’t said how many Duos it has shipped. With launch-weekend volumes, a few dozen public reports could still be a tiny failure rate. But a defect that shows up in the same place within hours is not normal wear, and the count could grow as more people get their phones. Apple’s second launch wave adds 28 more countries and regions on October 30.
What is causing the iPhone Duo screen crack?
The likeliest explanation so far is a mechanical problem in the hinge pressing into the display from below, not the glass or the screen simply giving way. No one has proven it, and Apple hasn’t said. Here are the leading theories and who is behind each one:
| Theory | Who proposed it | Evidence | Status |
|---|---|---|---|
| A hinge part doesn’t retract fully when closing and presses into the screen | iFixit | A 3D hinge model built from CT scans, teardown footage and Apple patents. Reported breaks cluster “near the transition from the gap for the crossing flex cable to the central hinge support.” In iFixit’s closing simulation, the center support bar “fails to drop far enough,” creating a stress hotspot | Hypothesis |
| Curved hinge rails rise above the flat plates and touch the screen | iFixit (via MacRumors) | One rail lines up with the damage location | Hypothesis |
| A thin middle hinge link snaps and hits the display | YouTuber CuriousHagi (via The Verge and AppleInsider) | After dirt and bending the hinge backwards, his Duo cracked. Inside, a link thinner than those above and below it had sheared at a small notch. There was an impact mark under the display and crush marks nearby | One unit, after deliberate abuse |
| Grit in the hinge | iFixit, JerryRigEverything | iFixit’s dust test made the hinge “crunch.” JerryRigEverything’s dust video left a Duo unable to stay shut, with grit in the hinge and its closing magnets failing (MacRumors) | Plausible for some cases, but early failures happened on brand-new, clean phones |
| A bad manufacturing batch | 9to5Mac readers and commenters | Failures look identical and show up early | Speculation |
Two more points from iFixit are worth knowing. First, the damage may be smaller than it looks. A tiny fault in the display’s wiring can light up a whole row or column of pixels, so a short crack can still produce a long white stripe. Second, the IP68 rating doesn’t make the hinge sand-proof. In iFixit’s words, IP certification covers the “enclosure,” which “doesn’t seem to include the hinge mechanism of a foldable.” The Duo did collect less dust than the Galaxy Z Fold8 or Pixel 11 Pro Fold in iFixit’s comparison.
Has Apple said anything?
Not publicly, as of October 26, 2026. 9to5Mac says it asked Apple for comment and hadn’t heard back. Apple’s actions so far:
- In-store replacements. MacRumors, 9to5Mac and iFixit all report that Apple Stores are giving affected buyers a new phone rather than repairing the old one. MacRumors suggests Apple is probably collecting the faulty units to find the failure point.
- A hinge support guide. Apple’s iPhone Duo hinge troubleshooting page covers phones that won’t fully open or close, make noise, or have a loose, bent or broken hinge. It states: “There aren’t diagnostics or software remedies for hinge issues.” The owner checks are basic: remove any third-party case or screen protector, open and close the phone, listen, and check that it holds every position with nothing caught in the fold. After that, the repair is a replacement of the inner display assembly. The page doesn’t mention cracks.
- No software fix. The Duo ships with iOS 27.1, a Duo-only release with “bug fixes” and no security content. iOS 27.2 is expected this week and will run on the Duo, but nothing suggests a software update can fix a hinge.
How much does an iPhone Duo screen repair cost?
An inner screen costs $999 (£999) out of warranty, about half the phone’s $1,999 starting price. AppleCare+ brings that down to $99 (£79). These are Apple’s own estimates. Apple inspects every phone first, and the final fee can differ.
| Repair | No AppleCare+ (US) | With AppleCare+ (US) | No AppleCare+ (UK) | With AppleCare+ (UK) |
|---|---|---|---|---|
| Inner (folding) display | $999 | $99 | £999 | £79 |
| Inner screen cover layer only | $49 | $19 | £49 | £19 |
| Outer display | $379 | $29 | £389 | £25 |
| Other damage | $1,499 | $99 | £1,499 | £79 |
| Manufacturing defect (in warranty) | $0 | $0 | £0 | £0 |
US out-of-warranty prices from Apple’s estimates as reported by MacRumors. AppleCare+ fees from Apple’s US and UK fee pages. UK out-of-warranty prices as reported by T3. Prices checked October 26, 2026.
AppleCare+ for the Duo costs $19.99 a month, $199.99 a year or $399 upfront in the US (per MacRumors), and £16.99 a month in the UK (per T3). The deciding question is whether Apple treats your crack as a manufacturing defect (free under the one-year warranty) or accidental damage (you pay). Apple’s warranty page says the Limited Warranty covers “manufacturing issues for one year” and doesn’t cover accidental damage.
Third-party repair isn’t a realistic shortcut yet. iFixit says it will sell inner screens “as soon and as affordably as we can,” but warns the part “won’t be cheap” and the job will be slow, adhesive-heavy work. Its provisional repairability score for the Duo is 5 out of 10, its highest ever for a foldable. The Galaxy Z Fold8 and Pixel 11 Pro Fold both scored 4.
What to do if your iPhone Duo screen cracks
Stop folding it, document it, back it up, and get it to Apple while you’re still inside the return window. Step by step:
- Stop opening and closing it. If the hinge feels tight or gritty, or the fold catches, don’t force it. One owner quoted by iFixit described a loud pop when they “pushed past” a tight hinge.
- Take photos and a short video of the crack, the white line and the hinge, with the date visible if possible. If there’s no drop damage, the photos help show that.
- Back up the phone while the outer screen still works: Settings > [your name] > iCloud > iCloud Backup > Back Up Now. If iCloud is full, see our guide to freeing up iCloud storage without paying.
- Don’t peel anything. The nano-texture cover layer is designed to be replaced by Apple with special fixtures. Removing it yourself can turn a warranty claim into a paid repair.
- Book an Apple Store Genius Bar appointment or start a repair in the Apple Support app. Say the screen failed during normal opening or closing and there was no drop. That’s the warranty case.
- If you bought from Apple, mention the return window. Apple’s US policy gives you 14 calendar days from the date you received the item to return it. Owners who bought from Apple have mostly been offered a straight replacement.
- If you bought from a carrier, the carrier’s own return rules apply. Apple’s return window only covers purchases made directly from Apple. Apple’s one-year warranty still covers manufacturing defects, so you can still take the phone to Apple. 9to5Mac reports one carrier customer was told they “must have dropped the phone.” If that happens, ask Apple to inspect it before you accept a paid repair.
- Transfer your eSIM to the replacement before you give up the old phone if it still works. Our eSIM transfer guide walks through it.
Extra rights for UK buyers
Under the Consumer Rights Act 2015, you generally have 30 days from delivery to reject faulty goods for a full refund. That’s separate from, and longer than, a retailer’s 14-day change-of-mind policy. The claim is against the seller (Apple, a carrier or a retailer), not the manufacturer. Which? explains the process.
How to lower the risk if your Duo works fine
There’s no confirmed way to prevent it, but these steps are sensible while the cause is unknown:
- Never fold it backwards or past fully open. CuriousHagi’s failure followed exactly that kind of stress, and AppleInsider warns against it.
- Keep the hinge away from sand, lint and grit. That means no beach trips and no loose pocket debris. iFixit’s dust test showed some particles reaching the hinge’s moving parts.
- Stop at the first sign of trouble. That includes crunching, a new click, tightness, or a phone that won’t hold its angle. Apple’s guide treats each of these as a hinge issue. Get it checked while you’re still in the return window.
- Treat social media “folding technique” tips with caution. Some people suggest not closing the Duo by pressing on the center of the inner screen. 9to5Mac says it’s “unclear if this is actually relevant advice,” and Apple hasn’t given any handling guidance.
- Decide on AppleCare+ quickly. In the US, Apple lets you add AppleCare+ within 60 days of purchase, including phones bought from a carrier, under Settings > General > AppleCare & Warranty (Apple). The phone has to be in working condition, so you can’t add it after the screen cracks. Check the window for your country in the same menu.
Should you still buy an iPhone Duo?
If you haven’t bought one yet, waiting two to four weeks costs you nothing and should give you a much clearer picture. If you already own one, you’re inside the window where Apple has been swapping faulty phones.
| Your situation | What we’d suggest |
|---|---|
| Thinking of buying | Wait for Apple’s response or a clearer failure count, especially with October 30 orders opening in more countries. Our iPhone Duo buying guide covers everything else |
| Bought from Apple, phone works | Keep using it gently and watch the hinge. You can return it within 14 days of delivery if you lose confidence |
| Bought from Apple, screen cracked | Back up, then go to an Apple Store for a replacement or refund |
| Bought from a carrier | Check the carrier’s return deadline today. Use Apple’s warranty for defects |
| UK buyer | You likely have 30 days to reject a faulty phone under the Consumer Rights Act |
| Planning to skip AppleCare+ | Reconsider. A single inner-screen repair costs $999, while AppleCare+ starts at $199.99 a year |

FAQ
Why is my iPhone Duo screen cracking?
Nobody has confirmed the cause yet. iFixit’s teardown points to a spot under the display where several hinge parts meet, possibly a support bar that doesn’t retract fully when the phone closes. One YouTuber found a snapped hinge link in his broken unit. Apple hasn’t commented as of October 26, 2026.
Does Apple replace a cracked iPhone Duo for free?
If Apple decides it’s a manufacturing defect, it’s covered free under the one-year warranty. Several owners who bought from Apple were given a replacement on the spot. If Apple decides it’s accidental damage, the inner screen costs $999 (£999), or $99 (£79) with AppleCare+.
How much is an iPhone Duo screen replacement?
Apple estimates $999 in the US and £999 in the UK for the inner folding display without AppleCare+, and $99 or £79 with AppleCare+. Replacing only the inner screen’s cover layer costs $49 without AppleCare+ or $19 with it.
Can I return my iPhone Duo if I’m worried about the screen?
Yes, if you bought from Apple and you’re within 14 calendar days of receiving it. Carrier and retailer purchases follow their own return policies. UK buyers also have a 30-day right to reject faulty goods under the Consumer Rights Act 2015.
Will iOS 27.2 fix the iPhone Duo screen crack?
There’s no sign it will. Apple’s hinge guide says there are no diagnostics or software remedies for hinge issues, and the reported failures look mechanical. iOS 27.2 is expected this week and will run on the Duo.
Is “Crackgate” happening to every iPhone Duo?
No. Public reports so far number in the dozens at most. AppleInsider found only one case across seven US Apple Stores by late October 25. The worry is that the failures look identical and happen early, so the count may grow.
