BYD and vivo sign strategic pact on cross-device AI agents

KEY FACTS

BYD and vivo announced a strategic partnership on November 5.
The two sides will push cross-device integration of AI agents between phones and cars.
The collaboration covers ecosystem coordination between smart devices and new energy vehicles.
The two companies have worked together since 2019 on phone-to-car connectivity and smart entry.
In August 2025, vivo's OriginOS already supported mirrored phone screen casting to BYD car head units.

PHYSIX OBSERVATION

Phone makers and automakers moving from screen-mirroring connectivity to cross-device AI agents is fundamentally a fight for the entry point to users' travel scenarios. For users it means an upgraded experience; for the industry it means ecosystem alignment accelerates, and smaller vendors will face higher compatibility costs.
