Beta enrollment runs through the Nothing Beta Hub via an APK installer.

Overview

  • The first open beta is live now for Nothing Phone (3), Phone (2), Phone (2a) and Phone (2a) Plus, with availability reported in India.
  • Phone (3a) and (3a) Pro are excluded at launch, with Nothing stating they will receive OS 4.0 in October; current CMF Phone models are not included.
  • Key additions center on AI features including AI‑generated Essential Apps, an AI Dashboard and an AI Playground, alongside new icon styles and an extra dark mode.
