Thanks for contributing.
Is this an issue already? Which browser do you use?
Anyway, that change isn't that easy because window is a global object that isn't used correctly across our whole project.
As far as I know there are browsers supporting Screen but do not return an angle or an unified angle at all.
We also have to consider change-events especially for our rendering on mobile devices.
Refactoring should be encapsulated in a global scope and reused across the project.
Have you considered to write it as:
let vo = window.orientation || (window.screen && window.screen.orientation) ? window.screen.orientation.angle : undefined

Ah I see the problems with my solution,

Should I implement the window orientation in smartjs/sj.js then use it across the whole project?
