Google announced that Android 17 will support Encrypted Client Hello across the operating system, extending a privacy protection previously available in some browsers. For supported websites and apps, ECH encrypts the destination website name so network providers and observers cannot easily identify the service being accessed. Android 17 will enable ECH GREASE by default, while OkHttp has added ECH support to its core library. The release also adds local-network permissions and allows participating carriers to disable 2G by default.
