It is a service that users can easily use applications, services and devices by reducing the execution steps through Voice (command) and Camera (Image recognition). It also recommends the personalized features based on the analysis of user's lifestyle at defined T/P/O. We named this service “Bixby”.

Galaxy S8/S8+ has dedicated hardware key for Bixby home and Bixby (under volume key) to offer easy access to its interfaces.
