Following the release of the new iPhone Duo, the repair advocacy group iFixit performed a detailed teardown to examine the device's internal components. The report provides a technical look at how Apple has engineered the folding mechanism and display. A primary focus of the teardown was the device's folding screen, which utilizes a matte nano-texture cover. According to iFixit, this material serves a dual purpose: it improves screen readability in bright environments and helps obscure the physical crease by scattering light reflections.

Under microscopic inspection, iFixit identified unique oval-shaped subpixels within the display, though the full implications of this arrangement were not detailed in the initial report. Regarding maintenance and longevity, iFixit assigned the iPhone Duo a repairability score of 5 out of 10. While this score is relatively low in the context of consumer electronics, iFixit noted that it is currently the highest repairability rating they have awarded to a foldable smartphone to date. The teardown also suggests that certain internal design choices may be linked to reports of screen and hinge durability issues, though the analysis stops short of confirming a direct causal link to widespread hardware failure.
