Apple’s first foldable iPhone has encountered an unexpected problem just days after reaching customers. Some early buyers of the iPhone Duo have reported cracks, bright lines and other display problems near the phone’s central folding mechanism.

The iPhone Duo screen cracks have prompted Apple to acknowledge a problem affecting a small number of devices. The company says customers experiencing these issues should contact AppleCare for a replacement.

The announcement, made on October 26, 2026, follows complaints shared on social media and technology forums.

While Apple has confirmed the display problem, the exact cause remains unknown. Meanwhile, repair specialists at iFixit have identified a possible mechanical weakness inside the folding mechanism.

Apple Responds to iPhone Duo Screen Cracks

Apple has acknowledged that some units of its newly launched iPhone Duo are experiencing problems with their inner displays.

According to Reuters, the company confirmed the issue on Monday, October 26, after images of damaged devices circulated online.

Apple indicated that the problem affects a small number of phones and advised customers with affected displays to contact AppleCare for replacements.

The company has not revealed the total number of affected devices or announced a specific technical cause.

This distinction matters. Although several customers have reported similar problems, there is currently insufficient public information to determine how widespread the defect might be.

For a smartphone built around a folding display, however, even a limited number of early failures can raise important questions about durability.

What Problems Are iPhone Duo Users Reporting?

The complaints primarily concern the iPhone Duo’s flexible inner display.

Unlike a conventional smartphone, the iPhone Duo opens like a book, allowing its larger screen to fold along a central hinge.

Some owners have reported problems shortly after beginning to use their devices.

Cracks Near the Folding Hinge

Images shared online show apparent cracks and other abnormalities near the center of the display.

The affected area is particularly important because it experiences movement whenever the device is opened or closed.

Bright Lines Across the Screen

Other reported symptoms include bright horizontal or vertical lines extending across parts of the display.

Such lines can indicate damage to the display’s electrical connections, although they do not necessarily prove that the entire screen panel has physically cracked.

Problems Appearing Within Hours

Some customers reported that their devices developed faults within hours of purchase.

According to iFixit’s examination of publicly reported cases, one owner experienced a problem within six hours, while another encountered an issue before completing the initial setup.

These reports suggest that at least some failures occurred unusually early in the devices’ lifespan.

However, individual customer experiences cannot establish the overall failure rate.

What Could Be Causing the iPhone Duo Display Problem?

The exact cause of the iPhone Duo screen failures has not been established.

Apple has not publicly confirmed whether the problem involves manufacturing defects, hinge alignment, internal display components or another technical issue.

However, an independent investigation by electronics repair specialist iFixit offers one possible explanation.

iFixit Investigates the Folding Mechanism

In a teardown report published on October 25, 2026, iFixit examined the internal construction of Apple’s foldable smartphone.

The repair specialists used teardown footage, patent information and CT scans to build a three-dimensional model of the device’s hinge.

They then compared the hinge’s internal structure with the locations where customers reported screen damage.

Their examination suggested that several affected areas were concentrated near a transition point between the display cable and the central hinge support.

This location could experience concentrated mechanical stress when the device folds.

Could an Internal Support Bar Be Responsible?

One hypothesis involves a support bar inside the hinge.

According to iFixit’s simulation, the support bar might not move sufficiently out of the display’s path as the phone closes.

If that happens, the flexible screen could press against the internal component.

Repeated or concentrated pressure could potentially damage the display.

However, this remains a technical hypothesis, not a confirmed diagnosis.

iFixit has not established that the support bar caused every reported failure, and Apple has not confirmed the theory.

Other explanations, including problems with nearby components, remain possible.

Apple Offers Replacements for Affected iPhone Duo Units

Apple’s immediate response focuses on helping customers whose phones are already showing display problems.

The company has advised affected owners to contact AppleCare and request a replacement assessment.

Reports indicate that customers do not need a paid AppleCare+ subscription specifically to seek replacement assistance for this acknowledged issue.

However, Apple has not published a comprehensive public breakdown of replacement eligibility for every possible form of display damage.

The distinction between a confirmed product defect and accidental damage remains important.

What Should Affected iPhone Duo Owners Do?

Customers who notice cracks, unusual display lines or other screen abnormalities can take the following steps:

1. Contact Apple Support: Explain the display problem and when it first appeared.
2. Document the issue: Take photographs of visible faults if possible.
3. Request an assessment: Ask AppleCare whether the device qualifies for replacement under the acknowledged issue.
4. Back up important data: Follow Apple’s preparation instructions before handing over a device.
5. Confirm the service arrangement: Ask about replacement availability, coverage and any applicable charges.

Customers should avoid attempting to repair the flexible display themselves.

Apple‘s official support channels can provide information about available service options.

Is AppleCare+ Required for a Replacement?

Reports indicate that an AppleCare+ subscription is not required for customers to seek replacement assistance for this particular acknowledged defect.

However, eligibility depends on Apple’s assessment of the individual device.

AppleCare+ is a separate paid service plan that provides additional coverage under its terms.

Customers should not assume that all cracked screens, including those damaged accidentally, qualify for a free replacement.

For this reported issue, the safest approach is to contact Apple directly and confirm the applicable coverage.

How Repairable Is the iPhone Duo?

Interestingly, iFixit’s investigation identified some positive aspects of the iPhone Duo’s construction.

The repair organization awarded the device a provisional repairability score of 5 out of 10.

Although that might not sound particularly impressive, iFixit described it as the highest repairability score it had given a foldable smartphone at the time of its assessment.

The device features relatively accessible internal components, removable batteries and an outer display that can be separated during servicing.

Nevertheless, repairing the flexible inner display remains complicated.

In the United States, iFixit reported a potential out-of-warranty inner-display repair cost of $999.

Apple’s Indian service website also lists a substantial estimated cost for out-of-warranty inner-display damage.

These standard repair prices should not be confused with Apple’s replacement response to the specific acknowledged issue.

Why the Screen Problem Matters for Apple

The iPhone Duo represents Apple’s entry into the foldable smartphone market.

The device’s launch attracted considerable attention, with Reuters reporting that initial online orders sold out quickly amid limited supply.

However, foldable smartphones present engineering challenges that conventional phones generally avoid.

Their displays must tolerate repeated bending while maintaining image quality, touch responsiveness and structural reliability.

The hinge is therefore more than a simple mechanical connection. It is a central part of the device’s long-term performance.

A problem involving this component can affect consumer confidence, especially when it appears soon after purchase.

An Important Early Test for Apple’s Foldable Strategy

Apple’s decision to offer replacements is an important first response.

Nevertheless, the company’s longer-term handling of the issue will matter just as much.

Customers will want to know whether the failures are isolated, what caused them and whether replacement devices are protected against the same problem.

The situation also recalls early display difficulties experienced by some competing foldable smartphones.

For Apple, the challenge is to demonstrate that its first foldable phone can deliver the reliability customers expect from a premium device.
