ByteDance and Nubia launch Doubao 2.0 AI phone with dedicated assistant button

ByteDance, the Chinese tech giant behind TikTok, and smartphone maker Nubia have debuted their second-generation Doubao AI Agent smartphone at the World Artificial Intelligence Conference (WAIC) in Shanghai. The device builds on the original partnership, which integrated ByteDance's Doubao large language model into Nubia's hardware. Leaked images reveal a sleek blue metallic chassis with a dedicated orange AI button — a physical trigger to summon the assistant. The phone runs an updated Obric UI, which has undergone 216 days of iterative refinement to better support AI-driven interactions.

The standout feature is the Doubao assistant's enhanced memory capability. It now constructs a persistent personal information database, allowing it to recall user preferences, past conversations, and contextual details across applications. This enables more intelligent cross-app operations — for example, pulling calendar events into a shopping list or summarizing messages across platforms. With this second-generation device, ByteDance and Nubia aim to push the AI smartphone concept beyond simple voice commands toward true proactive assistance. The launch comes amid fierce competition in China's AI handset market, with rivals like Xiaomi, Huawei, and Oppo also embedding large language models into their devices.
