In the second DP, Google is adding another 5G-related API -- the 5G state API checks whether a user is currently on a 5G New Radio or Non-Standalone network. Developers can use this to highlight their app's 5G experience or branding. 

This release also honors a top request from developers, giving them the precise hinge angle of a foldable device. Enabled by Android 11's new support for a hinge angle sensor, this lets developers build adaptive experiences. 

Google is also adding mutiple new features related to security and transparency, as well as general quality. For instance, with Android 11, apps can new resume on reboot, following an over-the-air software update. This gives apps access to Credential Encrypted storage after the OTA reboot, without the user unlocking the device, allowing the app to resume normal function and start receiving messages.
