TIER 1 --- Large screen differentiated
| **Objective:** Make your app [large screen differentiated](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality#large_screen_differentiated) by meeting the [LS-F1](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality#LS-F1) foldable postures and [LS-F2](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality#LS-F2) camera preview requirements of the [Large screen app quality](https://developer.android.com/docs/quality-guidelines/large-screen-app-quality) guidelines.

Foldable postures and states such as tabletop and [`HALF_OPENED`](https://developer.android.com/reference/kotlin/androidx/window/layout/FoldingFeature.State#HALF_OPENED()) invite app
innovation. Camera preview that supports both large and small screens of a
foldable device provides an optimal user experience.

Differentiate your app on premium foldable devices. Jetpack WindowManager APIs
such as [`FoldingFeature`](https://developer.android.com/reference/kotlin/androidx/window/layout/FoldingFeature) show you how.
