Smooth display animations, fluid drag-and-drop animations for widgets, folders, and icons, and new light-field motion effects are powered by the Luminous Rendering Engine.
Additional Features
The update includes new features and improvements such as touch to share files, OnePlus Connect, enhanced in-car Bluetooth pairing, a new interface for the AI LinkBoost Network Engine, and a dedicated page for AI settings.
