Multiple iPhone Duo units are developing cracks straight down the center of the screen after regular open and close cycles. This iPhone Duo screen cracking pattern, now dubbed iPhone Duo crackgate, shows up with a consistent green line or white streak running across the display.
The folding mechanism itself appears to be the culprit. Videos from owners reveal the same failure mode on fresh units, often within weeks of use. It is not an isolated defect but a recurring hardware stress point on the flexible display.
What owners are seeing
Early reports point to the hinge area placing repeated pressure on the screen layers. The result is a visible iPhone Duo green line that starts in the middle and migrates rightward. Owners describe the line appearing suddenly after a normal fold, with no drop or impact involved.
Warranty and Apple Care iPhone Duo
Apple has not issued a formal recall, yet the volume of identical failures suggests iPhone Duo warranty issues will be covered under standard replacement. Still, getting Apple Care iPhone Duo is the safest move until the root cause is addressed. Replacement units are already showing the same problem, so protection against out-of-pocket costs matters.

Stock and apps update
New 256 GB and 512 GB units sell out the same day they appear. Tools like InStock Radar help track daily drops. A new site at beardfm.app/dualapps lists apps already reformatted for the wide dual-screen layout.
Bottom line
If you already have an iPhone Duo, document any iPhone Duo green line immediately and open a support case. If you are still waiting for one, factor Apple Care iPhone Duo into the purchase. The pattern is clear enough that this iPhone Duo crackgate will likely drive a software or hardware revision soon.
