Apple held off on releasing a foldable smartphone until it was confident it had the perfect product, which was why the recently launched iPhone Duo arrived several years after the first Android foldable. Despite the company’s efforts, the device is not free from faults, as some users have quickly discovered. In fact, one particular problem involving the inner display has emerged.

Multiple reports have cropped up online claiming that the device’s foldable screen is prone to cracking and breaking. Notably, these displays show the same pattern upon breaking: a vertical line running down the centre of the phone, with a horizontal line stretching from it to the right half of the folding panel.
