Large-screen and foldable optimisations
The story
Large screens were growing quickly, and Android apps were not ready for them.
The problem
Apps forced portrait orientation and fixed layouts, so tablets and foldables showed stretched phone UIs.
Android 12L introduced a taskbar, improved split-screen, and window size classes, and began ignoring orientation restrictions on large screens.
The release that said large screens are the default, not an exception.
