A teardown by YouTuber CuriousHagi has suggested that a damaged hinge component could be involved in reported iPhone Duo screen cracks. The account offers a possible explanation for a recurring damage pattern, although it does not establish a common cause across the reported cases.
Reports of cracked screens emerged within hours of the iPhone Duo's release, according to the supplied article. Some reportedly developed around the crease and extended horizontally towards the display's edge, raising questions about whether the screen itself was breaking during bending.
