Nothing OS 4.0 Android 16 Closed Beta Announced for Phone (3) Users
Nothing has officially announced the Closed Beta program for its upcoming operating system update — Nothing OS 4.0, based on Android 16. This early build is now available exclusively for Phone (3) users who want to test the latest features before the official rollout. The company is offering this early access as a way to thank its early supporters.
In this Closed Beta, Nothing is focusing on bringing Android 16’s core features along with a stronger and more consistent design system. The new UI changes are expected to lay the foundation for a more polished and cohesive user experience in the future versions of Nothing OS.
Since this is a beta version, users can expect bugs and certain features not working properly. Nothing encourages users to join this program and help them identify and fix issues before the Open Beta release in September 2025. It’s a chance for users to be part of the development process and shape the final software.
To be eligible, participants must use the Phone (3) as their daily device. They should also be willing to provide regular feedback to the Nothing team, maintain information security, and understand that this early build may be unstable. Testing is expected to run from August 2025 to early September.
Nothing also warns users that this Android 16 build is in its early stages of development. Some features may be missing or not function properly. It is strongly recommended to back up your device regularly while testing. More details and disclaimers can be found in the sign-up form.
If you’re interested in joining, you need to fill out the form linked below before 5 PM BST on Sunday, August 3, 2025. Selected users will be informed via email within a week, along with complete onboarding instructions.
