Nothing will unveil the Phone (3a) and (3a) Pro on March 4, featuring a dedicated Essential Key for AI-powered functions. This button will activate Essential Space, an AI hub for storing screenshots, voice notes and photos. Users can press it to take a photo, long-press to record a voice note or double-tap to access stored content. While Essential Space is still in development, it will debut with these phones, with a more advanced version expected for the Nothing Phone (3).
