Apple's inaugural foldable smartphone, the iPhone Duo, encountered user feedback regarding screen malfunctions shortly after its launch, specifically within the first week. Users reported that after folding the device multiple times—ranging from a few folds to several dozen—cracks and dark patches emerged at and around the folding mechanism, leading to suspicions that the hinge might be the culprit. To maintain a steady supply, Apple had marginally loosened its quality control criteria. Presently, the manufacturing team has swiftly substituted materials, ensuring that production proceeds without interruption, with an ambitious target to stockpile 7.5 million units by the year's end. Rather than intensifying quality checks, Apple is focused on capitalizing on the burgeoning foldable smartphone market. The company is channeling efforts into multiple avenues to generate buzz around the product and enhance app compatibility. This launch is particularly crucial for Apple as it navigates a leadership transition within the company.
