Apple's first foldable smartphone, the iPhone Duo, has attracted significant attention since its launch. However, excitement surrounding the premium device has now been accompanied by concerns over its durability. Several users have reportedly complained about lines and cracks appearing on the inner display, particularly around the hinge where the screen folds.

The issue has raised questions about the reliability of Apple's first foldable smartphone. Following complaints from customers, Apple has acknowledged that some devices are experiencing display-related problems and has advised affected users to contact Apple Care for assistance.

Here's everything you need to know about the reported issue, its possible cause and how customers can seek help.

1. Apple Acknowledges Reports of Screen Damage

According to a Reuters report, Apple acknowledged on Monday that certain iPhone Duo units are experiencing problems with their inner displays.

Some customers have reported visible lines and cracks near the folding mechanism. Photographs showing damaged screens have also circulated on social media, bringing further attention to the issue.

Apple has advised customers experiencing these problems to contact Apple Care for assistance and possible replacement of affected devices.

However, the company has not publicly established the exact reason behind the reported display failures.

2. Why Is the iPhone Duo's Inner Display Getting Damaged?

Repair specialists have also examined the device to understand what might be causing the problem.

According to a teardown analysis by repair information company iFixit, a possible concern involves the positioning of the display cable and the supporting structure beneath the screen.

The analysis included a CT scan that was used to create a three-dimensional view of the phone's hinge mechanism.

According to the findings, the display cable passes close to a support bar underneath the screen. During the folding and unfolding process, the positioning of this support structure may create pressure on the display if it does not move as intended.

This pressure could potentially contribute to screen damage over repeated use.

However, this is a technical explanation of a possible design-related issue and has not been confirmed as the official cause by Apple.

Interestingly, iFixit also described the device as relatively repairable compared with some other complex smartphones.

3. How Can Customers Get a Replacement iPhone Duo?

Customers who notice unusual lines, cracks or other display defects on their iPhone Duo should contact Apple Care.

The process generally involves the following steps:

1. Contact Apple Support through its official website or support application.

2. Explain the display problem and share photographs if requested.

3. Arrange a device inspection or diagnostic assessment.

4. Follow Apple's instructions regarding repair or replacement eligibility.

Customers should avoid attempting to open or repair the foldable display themselves, as doing so could cause additional damage.

It is also advisable to keep the purchase invoice and warranty details readily available while contacting customer support.

4. Why Apple's Replacement Decision Matters

Apple's decision to provide assistance to affected customers is important because foldable smartphones are still a relatively new and technically complex product category.

The inner display and hinge mechanism require careful engineering, as they experience repeated physical movement during everyday use.

IDC Vice President Francisco Jeronimo reportedly described Apple's response as the right approach. He also drew comparisons with early problems experienced by Samsung's Galaxy Fold series, suggesting that addressing such issues quickly can help protect consumer confidence and a company's reputation.

For a premium smartphone, customers naturally expect high standards of durability and after-sales support.

5. What Should Existing iPhone Duo Owners Do?

If you have already purchased an iPhone Duo, it is worth paying attention to the condition of its inner display.

Look for unusual horizontal or vertical lines, cracks near the folding area, flickering or changes in display brightness.

If you notice any of these problems, avoid repeatedly folding or pressing the affected area. Contact Apple Care and get the device inspected.

Also, avoid using sharp objects near the hinge and follow the manufacturer's instructions for handling the foldable display.

Final Words

The reported iPhone Duo display problems have raised concerns about the durability of Apple's first foldable smartphone. Although the exact cause remains unclear, the technical investigation has highlighted a possible connection between the hinge support structure and the inner display.

Apple's replacement support for affected customers could help maintain consumer confidence. However, the company's long-term response and any improvements to future devices will be important in determining how successfully it addresses these concerns.
