Android 11 developer preview was launched by Google in middle of February. It is 18th version of the Android mobile operating system. Stable version might be launched in third quarter of the year.
Many new features are included in developer preview build such as enhancements to support for foldable smartphones, 5G, Project Mainline (servicing of system components via Google Play Store), and High Efficiency Image File Format (HEIF). Support for STIR/SHAKEN call authentication will also be included.
Google also stated plans for a "dedicated conversation section in the notification shade", the ability to only grant certain permissions to apps on a case-by-case basis (similarly to iOS 13), and to introduce stronger enforcement of the "scoped storage" system.
Android 11 also features a native screen recorder which adds functionality to record the screen of phone. It also has notification history which will let you see dismissed notifications. It also got a feature to increase the sensitivity of the touchscreen and lastly you could also mute notifications while filming the video from your smartphone.
Currently the latest developer preview build is Developer Preview 2(RPP2.200227.009) which has released on March 18, 2020.
The Google Pixel series will be the first to get this new version of Android 11 stable build.
