Useful to know
Four things worth knowing.
Where it stops.
Platforms can change rendering, safe areas and limits, and a technically valid asset can still be cropped or truncated in a live placement.
What to inspect.
Preview it at phone size and keep important text, faces and logos away from platform UI and edges.
Worth knowing.
Preview it where it will actually appear, especially on a phone. The platform UI is part of the layout whether you designed for it or not.
