As with Android 10, privacy and security will play important roles. Users can now grant one-time permission to apps, and get better protection for data on external storage. Android 11 also supports finer-grained biometric authentication, more secure data sharing and digital IDs like driver's licenses.

Don't rush to install this unless you know what you're getting into. Like past Developer Previews, this is meant for coders who want to get their apps ready for the new version's official release later in the year. You'll need at least a Pixel 2, and you have to flash a device image to even try it. If you aren't a developer, you'll want to reserve this for a secondary device. All the same, this gives an idea of where Google is headed with Android 11.
