HomeLin Xi, Head of ByteDance's Doubao Phone, Departs from AI Hardware Team
According to Finance, Lin Xi, a key member of ByteDance's AI hardware division (Ocean) and head of Douyin's mobile hardware products, has recently confirmed his departure. As the first senior hardware executive to leave since ByteDance initiated its AI phone project in 2024, this move has sparked significant industry interest in the progress of the company's AI hardware strategy.
Public records indicate that Lin Xi previously spent many years at Huawei Terminal, where he served as hardware product manager for the Pura X foldable phone, accumulating extensive experience in hardware R&D. In 2026, as ByteDance ramped up its AI phone project, Lin joined ByteDance's Ocean team, reporting directly to Kayden (Liu Chengcheng).
This key personnel shift occurs at a pivotal moment for ByteDance's large model hardware deployment. On December 1, 2025, ByteDance's AI assistant 'Douyin' partnered with ZTE to launch the engineering prototype Nubia M153, which includes a preview version of the Douyin phone assistant technology. Positioned as a system-level AI assistant, the product aims to transform smartphone OS user experience by harnessing the Douyin large model's capabilities and deep integration with smartphone manufacturers.
