Apple Admits to Inner Display Flaws in Small Number of iPhone Duo Units

Apple has confirmed that a small number of iPhone Duo units are experiencing a defect in their inner displays. The company stated in a response to Bloomberg and 9to5Mac that it is aware of an issue impacting the internal screen on these specific devices.

Users have reported that the cracks appear quickly on affected units. The damage typically manifests as a bright line running from the center of the screen to the right side. Alex Kirschner, who shared the company's statement with The Verge, noted that most units are not susceptible to the problem. He added that when the defect does occur, it appears rapidly.

Apple advised owners experiencing display issues to contact AppleCare for a replacement. The company highlighted the positive early response to the iPhone Duo, noting that developers are quickly updating applications to utilize the device's unique form factor. This acknowledgment comes as some of the first products launched after John Ternus succeeded Tim Cook as chief executive.

Reports of the defect began shortly after the device's launch. Customers described instances where the hinge tightened, causing a crack in the display when the phone was opened. One user in Australia reported that an Apple Store replaced their unit immediately upon inspection.

Technical analysis supports the user reports. iFixit published a teardown of the phone this weekend, providing insight into the potential cause of the cracks. The examination showed that the foldable screen may be pushing against a center bar in the device's structure. This mechanical pressure could explain the distinctive bright lines observed on the damaged screens.

The Verge reached out to Apple regarding the reports but did not receive an on-the-record response from the company. The written statement served as the primary official communication on the matter. The defect affects the inner display, which is visible when the device is fully unfolded.
