ByteDance launches Doubao Phone Assistant consumer version with beta screen-automation controls
ByteDance
ByteDance officially launched the consumer version of its system-level Doubao Phone Assistant on September 14, adding screen-based Q&A, local search across photos and messages, voice activation, and a beta 'operate phone' screen-automation mode built on the SAEP protocol, which lets third-party apps declare boundaries and opt out of AI-driven operations. It ships first on the Nubia NaviX Ultra agent phone.
Why it matters
This is the first at-scale consumer product that puts an agentic assistant in control of a phone's apps, and its SAEP opt-out protocol is an early template for how app developers and agents negotiate boundaries.
