Apple has confirmed that a small number of its newly released iPhone Duo models are experiencing screen problems, prompting the company to offer replacements. Users have shared images online showing lines and cracks on the foldable displays, with some reporting a crunching sound when opening the device. The issue has raised concerns about the durability of Apple's first foldable phone, which starts at £1,999 in the UK. While Apple has not disclosed the exact number of affected units, some images may have been generated using AI, according to technology analyst Francisco Jeronimo. He noted that while caution is needed, the early reports highlight the challenges even a company like Apple faces in mastering foldable technology.
