Following the release of Apple's inaugural foldable iPhone, a number of users have encountered issues, including atypical sounds during regular unfolding and screen fractures along the central hinge, prompting conversations about its robustness. Numerous instances of these malfunctions transpired without any external impact and might be linked to the folding mechanism and screen dependability. Apple has confirmed that a limited quantity of iPhone Duo devices exhibit inner screen defects and recommends that affected users reach out to AppleCare for replacements. Nevertheless, the replacement procedure has been far from seamless (note: corrected the translation of 'Not smooth' for clarity and naturalness), with customers in various areas encountering obstacles in arranging after-sales service appointments, enduring extended waits owing to part shortages, and even situations where repairs are unfeasible. Analysts highlight that the technical hurdles associated with foldable screens persist despite Apple's foray into the market. The iPhone Duo continues to confront numerous challenges, encompassing pricing, durability, software compatibility, and consumer adoption. The ongoing attention to quality assurance and after-sales support will be pivotal for its success in the marketplace.
