Under the surface, the update is a surgeon. Permissions are trimmed like excess tissue: an app that used to burrow into contacts now finds its reach reduced. Sensors gain finer calibration. The gyroscope’s whisper aligns more faithfully with the hand’s intent; the proximity sensor learns to trust a cheek without false triggers. In the locker of the system, a small daemon awakens—an optimizer that tidies caches, compresses logs, and writes a faint footprint into the device’s memory: zxdz01_update_2026-03-22.
