豆包手机二代（搭载豆包手机助手二代的努比亚NaviX Ultra）在WAIC 2026期间正式亮相，备货量从初代的3万台大幅提升至20万台[1]。初代豆包手机于2025年12月发售，首批3万台当日售罄，其后在二手市场上溢价至3.6万元[1]。然而初代采用的GUI视觉模拟点击技术引发了微信、支付宝、美团等超级应用的风控机制，导致这些应用集体对其进行封禁[1]。
面对初代的困境，豆包手机团队在二代产品中做出了重大调整[1]。二代放弃了GUI方案，转而采用MCP（模型上下文协议）驱动技术，这要求应用方主动开放接口和权限[1]。字节体系内已有数十款应用支持这一新协议方式，实测表明其响应速度相比GUI方案有明显提升[1]。二代产品由字节提供大模型能力，与努比亚进行ODM合作，由中兴负责硬件整合，采用轻资产模式运营[1]。
7月15日，网信办首次公布了手机端侧生成式AI服务备案名单，努比亚豆包手机大模型获得了合规身份[1]。
Doupackage Phone Generation 2, powered by the Doupackage Phone Assistant Gen 2 running on the Nubia NaviX Ultra device, made its official debut during WAIC 2026, with inventory scaling up from 30,000 units for the first generation to 200,000 units for the second generation [1]. The new model represents a fundamental departure from its predecessor's technical approach, abandoning a GUI-based visual simulation method in favor of the MCP (Model Context Protocol) framework that requires direct cooperation with application partners [1].
The first-generation Doupackage Phone, which launched in December 2025 with an initial 30,000-unit allocation that sold out on the same day, faced widespread blocking by major applications including WeChat, Alipay, and Meituan after triggering their risk-control mechanisms through its GUI visual click-simulation technology [1]. Generation 2 addresses this challenge by shifting to MCP-driven interactions, necessitating that applications voluntarily open their interfaces and permissions rather than attempting to bypass existing safeguards [1]. Dozens of applications within the Bytedance ecosystem have already integrated support for the new protocol, with field testing demonstrating significantly faster response times compared to the GUI approach [1].
The second-generation device operates on a lightweight asset model, with Bytedance providing large language model capabilities, Nubia handling ODM partnership and product development, and Zhongxing managing hardware integration [1]. On July 15, the Cyberspace Administration released the first-ever compliance registry for on-device generative AI services on mobile phones, with Nubia's Doupackage Phone large language model obtaining official recognition on the list [1].
