155 apps reject Doubao Phone Assistant's SAEP protocol, leaving its agent vision stalled
TMTPost's Guangzhui Intelligence reports that Doubao Phone Assistant published the results of its Screen Automation Execution Protocol (SAEP) disclosure period on Oct 14, listing 155 apps that formally refused to let its AI act on their behalf — including WeChat, QQ, Taobao, Alipay, Meituan, Kuaishou, DeepSeek, Kimi, Pinduoduo, Xiaohongshu, WPS and several bank and carrier apps, with 66 Tencent-linked and 23 Alibaba-linked entries. ByteDance framed SAEP — with its three layers of app-declared boundaries, centralized policy decisions and system-level enforcement — as a way to set rules for GUI agents, but the report attributes the refusals to lost traffic gatekeeping and privacy worries, noting WeChat and Alipay had already triggered risk controls against the first Doubao phone. The piece contrasts this with StepFun's STEPX Neo, launched Oct 13, which takes an MCP+A2A approach and whose Amoo agent has partnerships with nearly 100 companies including Alipay, Tencent, Ctrip and Meituan, and with Meta's Muse, which Amazon cut off from shopping 13 days after launch.
It shows that an AI agent becoming the phone's main entry point still depends on whether super-apps will give up traffic and data control.
