OnePlus has started rolling out the stable OxygenOS 16 update for the OnePlus Open in North America, nearly a month after the update first arrived in India. Indian users received the stable build in November, followed by a smaller update in early December, while other regions were left waiting.

The update is being released in stages, so it will not reach all devices at once. OnePlus has said the rollout will expand to more regions over the next few weeks. For North America, the update arrives with build number CPH2551_16.0.1.300(EX01).

OxygenOS 16 is largely focused on improving how the system feels in daily use. Animations are smoother and more consistent across the interface, with better timing when opening, closing, or switching between apps. Drag and drop actions on the Home screen, widgets, folders, and the Smart Sidebar feel more fluid, and scrolling now follows touch input more closely. Transitions in the status bar, notification shade, and Quick Settings are smoother and can be interrupted mid gesture. Common actions such as charging, fingerprint unlock, audio controls, and long press actions across system apps now use updated animations with softer lighting effects.

Under the hood, performance improvements come from the updated Trinity Engine. It adjusts system resources in real time to keep performance steady during gaming, video playback, and long camera sessions. Background activity is better controlled during heavy use, helping reduce power drain. Games benefit from more stable frame rates, while pop up windows and video calls are handled more efficiently. Apps open faster from the Home screen, photo albums load quicker, and cached video previews appear sooner in supported third party apps. Power Saving mode now scales performance based on the remaining battery level.

OnePlus has also expanded its AI features across OxygenOS 16. Mind Space now supports voice memory recording by pressing and holding the Plus Key, including landscape capture. A new Mind Assistant makes it easier to search saved content and manage collections. The Photos app has been redesigned with simpler navigation, improved album sorting, and expanded video editing tools such as trimming, transitions, speed controls, filters, and background music. Motion photos can be turned into slow motion clips or collages without losing HDR quality.

Notes now supports block based editing, richer text formatting, image view switching, and one link sharing for full notes. The Recorder app gets a new layout, AI noise cancellation, automatic context detection, and easy sharing of audio files, transcripts, and summaries. AI Translate has been refined for smoother real time use. AI Writer is now available system wide, allowing users to generate text, summaries, tables, and mind maps directly inside apps. AI VoiceScribe and Call Summary also offer better context detection and more export options.

Design changes include the new Flux Home screen with light field style icons, customizable grids, folders, widgets, and a cleaner layout without icon labels. AI powered Flux themes add motion wallpapers, adaptive icons, Always On Display updates, and real time customization. Core apps such as Clock, Calculator, and Compass have also been refreshed.

The update also improves connectivity with features like Touch to Share, better OnePlus Connect PC mirroring, cross device clipboard and search, improved in car Bluetooth, My Devices controls, stronger network sharing, and smoother data transfer from iOS. On the security side, OxygenOS 16 adds warnings for risky apps and new options to lock or hide apps directly from the Home screen.
