To be clear, little is still currently known about Fuchsia.
Very little is known about Fuchsia, including big questions like whether or not it's designed to replace Android entirely. Even its release is up in the air, as several of Google's projects have never see the light of day. A Fuchsia developer, however, publicly stated that Fuchsia "isn't a toy thing, it's not a 20% project, it's not a dumping ground of a dead thing that we don't care about anymore."
At one point, the familiar Android notifications bar and on-screen buttons appear at the top and bottom, but it's unlikely to be part of Fuchsia.
The time and battery indicator are on the bottom instead of at the top, where you'd normally see them on Android.
Here's another example of apps and settings feeling like an overlay that hovers on top of the OS.
This seems to be the quick settings for Fuchsia, which we'd normally find in Android's notification shade.
Opened apps appear to hover above the Fuchsia OS rather than taking up the entire screen.
When we normally open an app on Android or iOS, it usually takes up the entire screen and it completely replaces the OS. In Fuchsia, it looks like the app is more of an overlay on top of the OS, judging by the gray bar below the orange email app.
