Nothing has announced the OS 3.0 beta, based on Android 15, for its smartphones. The stable release is expected in December, but users can join the Open Beta now, starting with the Nothing Phone 2a. Other models like the Phone 2, Phone 1 and CMF Phone 1 will join later.
Key features include upgraded lock screen options, AI-powered app organization, a redesigned Quick Settings panel and improved camera performance. However, as this is a beta, users should back up data and avoid using it on primary devices due to potential instability.
