Teardown of Apple iPhone Duo points to potential hinge design flaw
Independent testing suggests that recurring screen failures on the iPhone Duo may stem from a complex hinge mechanism putting stress on the display.
Owners of Apple’s iPhone Duo have reported widespread issues involving screen failures occurring at the device's hinge. Users frequently describe an audible cracking sound followed by immediate damage to the display panel, with the failures consistently appearing in the same location.
Tech analyst CuriousHagi conducted a stress test and subsequent teardown to investigate the root cause. The disassembly revealed a intricate hinge assembly comprised of a central gear-like mechanism and two distinct types of linking hinges.
The findings suggest that the complexity of the hinge design may cause mechanical interference, placing undue pressure on the internal display component. Apple has yet to issue an official statement regarding the frequency of these failures or potential manufacturing defects.
