- Scrolling screenshots. A “Capture more” button extends a screenshot of scrollable content. Standard views work without changes; custom UIs use the new scroll capture API.
- AppSearch. An on-device full-text search engine, with a local index through Jetpack and a central system index.
- Privacy indicator insets.
WindowInsetsreports where the camera and microphone indicators can appear, so immersive apps keep controls clear. - Enterprise toggles. Admins of fully managed devices can restrict the camera and microphone toggles.
- Companion apps. Apps paired through Companion Device Manager can start foreground services from the background by declaring a new normal permission.
- Auto-rotate. On Pixel 4 and newer, face detection with the front camera decides when to rotate, inside Private Compute Core.
- Games. Game Mode APIs and play as you download.
Beta 3.1 fixed a boot loop after restart, System UI crashes, and the low
memory killer daemon (lmkd) killing too many processes.
