ZTE's Nubia Unveils NaviX Ultra, Billed as 'World's First AI Agent Smartphone' Built Around ByteDance's Doubao

ZTE Corp.'s nubia brand has publicly showcased a smartphone it calls the "world's first AI agent smartphone," the NaviX Ultra, a device co-designed with ByteDance and built around the Doubao AI Assistant rather than a conventional app grid. The move marks the state-backed Chinese telecommunications maker's most explicit attempt to reimagine the mobile device with artificial intelligence at its core, joining a widening field of Chinese firms racing to make AI the primary way users interact with their phones.
