Early adopters of the iPhone Duo have reported screen failures shortly after purchase. Users describe a sudden increase in hinge resistance, followed by audible clicking or snapping sounds when unfolding the device. This physical stress leads to permanent damage on the inner display, characterized by a vertical bright line at the crease and a secondary horizontal line or pixel defect on the right side.
The timing of these failures varies, with some occurring within hours of initial use and others after several days. Affected owners state that the devices were not dropped or mishandled. While Apple is currently offering replacement units, supply constraints for the 1TB and 2TB models have made obtaining replacements difficult for many customers.
Apple has not yet issued an official statement regarding the cause of the malfunctions. Industry observers suggest that potential assembly errors or misaligned internal components within the hinge mechanism may be exerting excessive pressure on the flexible display. It remains unclear how widespread the issue is, as many reviewers and users have not experienced these problems.
The iPhone Duo is positioned as a premium flagship, making hinge reliability a critical factor for the product line. Experts suggest that if the number of reported cases continues to rise, the company may need to conduct a thorough investigation into its manufacturing and assembly processes to address potential quality control concerns.
