The beta version of Android 11 comes with lots of security and privacy changes designed to protect users’ data from malicious attacks. Android 11 will allow users to grant apps temporary permissions to access the device’s location, microphone, and camera using one-time permissions. The OS will also use SSL sockets based on Conscrypt’s SSL engine by default and the Scudo Hardened Allocator to service heap allocations as a mitigation measure against some memory safety safety. Google Android Engineering VP Dave Burke: “Android 11 has even more granular controls for the most sensitive permissions”””
