Apple’s recent iOS 17.5.1 update addressed a peculiar issue where long-deleted photos were reappearing on devices, an anomaly initially attributed to “database corruption.” This problem, which affected a minor number of users, involved old files, including sensitive images, surfacing on iPhones without prior presence. Apple clarified that the glitch stemmed from a corrupt database entry within the device’s file system, affecting only local files and not those synced to iCloud. The company reassured that it does not access users’ photo or video files and emphasized that content is permanently erased following a complete device reset, countering claims of data persistence post-wipe.
