What does the Nothing OS 4.0 offer?

Pop-up view multitasking becomes more convenient too, with support for two floating icons, and a new app optimisation setting promises quicker launch times.

Essential Space upgrades and community-driven tools

Nothing is bolstering its Essential Space with several notable enhancements. Flip to Record now supports taking photos and adding notes during video capture, bundling all content together for quick access.

A new “Playground” (Alpha) section invites users to explore community-created tools such as Essential Apps, Camera Presets, and EQ profiles. Essential Apps themselves are now available to download in preview form, blending AI-powered features with user-led creativity.

Visual refresh and smoother performance

Nothing OS 4.0 delivers a refreshed aesthetic, including redesigned app icons and cleaner status bar elements. Two additional lock screen clocks have been introduced, and an Extra Dark Mode offers a deeper and more immersive look for those who prefer a darker interface.

Improved animations aim to create a smoother, more fluid user experience across the system.

Glyph upgrades and camera improvements

The Glyph Interface gains more customisation, including the ability to choose whether Flip to Glyph triggers Silent or Vibrate mode. Glyph Progress now uses Android 16’s Live Update notifications, boosting compatibility with third-party apps.

The camera sees a substantial update with new presets, an expanded set of filters with intensity controls, Motion Photos with longer capture and audio support, refreshed watermarks and artistic frames, and a redesigned UI with better interaction flow.

Limited rollout for now

According to Nothing, the stable update is currently being delivered to a limited pool of Phone 3a and Phone 3a Pro users. A wider rollout will follow once the company confirms that the initial deployment is stable. Backing up data before installing the update is strongly recommended.
