Apple’s first foldable smartphone, the iPhone Duo, has come under scrutiny after reports of cracks in its inner display raised questions about the design of its hinge.
Initial analysis suggests that a metal component inside the phone’s mechanism may be putting pressure on the screen and damaging it.
Just hours after sales began, some users shared photos and videos on social media showing cracks directly above the hinge and bright lines on the right side of the display.
An Australian user said the screen cracked after making a cracking sound while opening the phone. Apple replaced the device after the user filed a complaint.
Experts say the gears, springs and other components inside the hinge help the screen bend and make room for the folding mechanism. However, one of these components may be coming into contact with the inner display.
According to experts, the hinge’s central support bar may not move down far enough every time the phone is closed. If this happens, the folded screen could come into contact with a metal component, concentrating pressure at a specific point and increasing the risk of cracking. However, this remains a possible explanation rather than a confirmed cause.
Apple has also acknowledged that the inner screens of some iPhone Duo units have been affected.
The company has advised affected users to contact AppleCare to arrange device replacements. However, it has not disclosed the exact number of affected devices or confirmed the cause of the problem.
Experts say foldable phones have delicate flexible displays and complex hinge mechanisms, making early defects possible. However, if similar complaints continue over the coming months, the issue could develop into a wider problem, potentially prompting a recall or design changes.
