Early iPhone Duo owners report hinge-caused screen lines

Early buyers of Apple’s first foldable, the iPhone Duo, are posting reports of inner display damage they say followed a hinge malfunction. The accounts, shared widely on a dedicated iPhone Duo subreddit, describe a consistent pattern: a vertical line down the center of the inner screen with a horizontal line extending from it on the right half.

What users are describing

According to multiple posts and images credited to Reddit users including scary_duck23, Vishnu_RK and Bitter_Offer7123, the sequence begins with the hinge feeling unusually stiff. When owners pushed past that resistance they reported hearing a popping or cracking sound and then seeing permanent lines on the folding display. Some users said the fault appeared within hours of first use; others said it developed after several days. Many who posted also stated they had not attempted to tamper with the phone and that they had prior experience with other foldable phones.

Apple response and likely scope

Users contacted Apple and carriers to seek replacements. Apple has offered replacements, but several owners report difficulty securing one because supply is limited, particularly for the 1TB and 2TB variants. At present it is not possible to state the root cause with certainty. The shared detail that the hinge resisted movement before the screen failed makes a hinge-related defect the most plausible explanation, but the reports could reflect a limited batch of affected devices: the problem has not appeared in many other user accounts or in the reviews published so far.

If you see these display lines contact Apple support promptly to request a replacement.
