Zepp OS 3.x New Features
Zepp OS 3.x brings a very rich set of new features.
New screen adaptation solution
The screen shape is abstracted so that the developer's layout on a round, square, or ribbon screen can be used for all devices with that type of screen, and the developer does not need to adapt it for the characteristic device.
Refer to Screen Adaptation
Background services and system events
The Mini Program supports long services that run in the background, and short services that are evoked based on events, bringing very many new possibilities for the Mini Program, such as continuous monitoring of health data through background services.

Canvas
Canvas enables more flexible view rendering and provides the underlying ability to build complex UI
