Nothing OS 4.0 (Android 16) Update: Features, Supported Devices

Nothing users have been waiting a long time for the Android 16 update — and finally, the company has officially revealed the rollout date. The open beta of Nothing OS 4.0 began in late October, and now the brand has confirmed that the public stable rollout will begin this Friday, 21 November.
The announcement was made on the Nothing Community platform, thanking beta testers and confirming that “the wait is almost over.”

Nothing OS 4.0 (Android 16) Name: ‘Flow’ – Smooth, Minimal & Natural UI

Nothing has focused on delivering a smoother, more fluid and natural UI experience this year. Inspired by the global trend, the Android 16 update is officially named ‘Flow’.
Just like Apple’s iOS 26 Liquid Glass design and Vivo’s upcoming OriginOS 6, Nothing OS 4.0 aims to offer a clean yet premium interaction experience while staying true to Nothing’s signature minimal aesthetic.

Users can now open apps in a floating window, making multitasking much faster — especially useful for chatting and browsing side-by-side.
