TL;DR
- The iPhone Duo's inner screen can develop a "stress hotspot" due to contact with its complex hinge mechanism.
- This stress point is where the flexible screen pushes against parts of the hinge, especially where the center support bar interacts with a crossing flex cable.
- Visual evidence and user accounts suggest that damage often appears as a black spot on the display, correlating with where the hinge's metal components meet the screen.
- While Apple states the issue affects a "small number" of units, the exact prevalence is unknown.
- This is considered a first-generation issue, and experts predict Apple will redesign the faulty hinge for future foldable iPhones.
- Despite these issues, many users are reportedly using the phones without problems.
