**[Doubao Mobile Assistant Official Release: GUI Operation App Retained, but Apps Can Reject AI Operations]** Dongcha Beating AI News: Doubao has officially launched the consumer version of its mobile assistant. It remains an AI assistant software that collaborates with smartphone manufacturers at the system level. The first mass-produced device, the Nubia NaviX Ultra, was previously announced and is set to launch and go on sale on September 16. The most controversial "phone operation" feature has not been removed and is still retained in Beta form. Doubao has also introduced the SAEP (Screen Automation Execution Protocol), which allows third-party apps to specify whether AI can perform screen reading, clicking, and execution operations within the app. If explicitly rejected, Doubao will cease automated operations. In a July report by *LatePost*, it was revealed that the new generation of Doubao phones will no longer rely directly on GUI operations for super apps like Alibaba and Tencent. Instead, Doubao can only access relevant data and functions if these apps actively open up MCP (Mobile Control Protocol) services. MCP refers to interfaces actively provided by apps to Doubao, while SAEP governs the extent to which developers allow Doubao to perform screen reading and simulated clicking operations on their apps. Both mechanisms now coexist. [Original Link]
