Nothing has added audio call recording to its smartphones via an update to Essential Space. Users can start recording by long-pressing the Essential Key or tapping the in-call notification, with recordings saved automatically afterward. The server-side update requires no manual installation and is currently available for the Nothing Phone (3), (3a), and (3a) Pro in eight countries, including India, Japan, the UK, and South Korea, with more regions coming soon.
