What users are seeing
A Reddit post by user MICAPe9 shows a clear gap between the back panel and the hinge of the Apple iPhone Duo when the device is closed. The video reveals the back of the phone lifting slightly, exposing the hinge mechanism. Other commenters, such as MrOsterhagen, confirm that the gap is visible on their own units and that the top half of the device shows a small bow.
Within hours of the iPhone Duo launch on 23 October, multiple owners posted images of damage to the right‑hand side of the inner display. The damage appears in the same spot on several phones, suggesting a systemic issue with the hinge that can stress the flexible screen.
Apple’s response
Apple analyst Mark Gurman highlighted the problem on X, and Apple later issued a brief statement. The company said it is aware of an issue affecting the inner display on a small number of iPhone Duo units and advised owners to contact AppleCare for a replacement. No further technical details were provided.
Why the launch feels rushed
Apple entered the foldable market later than rivals such as Samsung and Motorola. The expectation was that Apple would launch a polished product that solved the crease problem seen on earlier foldables. While the iPhone Duo does feature a matte finish that reduces the visibility of the crease, the hardware gaps and screen cracks indicate that the design may not have been fully refined.
Competing devices like the Samsung Galaxy Z Fold 8 were announced alongside the iPhone 18 and iPhone 18 Pro at Samsung’s September “Surprise and Shine” event, but the Z Fold 8 did not ship with the flagship models. The iPhone Duo finally reached stores on 23 October, yet many third‑party apps were still not optimized for the new form factor when reviewers received their samples.
Comparisons with competitors
Compared with the Samsung Galaxy Z Fold 8, the iPhone Duo offers an IP68 rating for water and dust resistance, but the reported hinge gap raises questions about the real-world durability of that seal. The Galaxy Z Fold 8 has also faced early reports of screen stress, but Apple’s reputation for premium build quality makes the Duo’s issues more surprising.
Other Apple products such as the Apple Watch Series 10 and iPad Air M2 continue to receive positive feedback, highlighting that the problems seem isolated to the foldable line rather than the broader ecosystem.
What to watch for
Potential buyers should inspect the hinge area carefully before purchasing a used iPhone Duo and consider contacting AppleCare if a gap is visible. The phenomenon has been dubbed “GapGate” by some users, echoing earlier “CrackGate” concerns about screen durability. If Apple resolves the issue with a repair program or a revised hardware revision, the Duo could still become a strong contender in the foldable market.
For now, the iPhone Duo launch remains a bumpy start, but the device’s unique features and the loyalty of Apple fans may keep it afloat unless hardware problems persist.
