Google announced Android 17 network security protections headlined by OS-wide support for Encrypted Client Hello (ECH), with ECH GREASE enabled by default so connections to non-ECH servers look identical. Google's Jigsaw noted OkHttp has integrated ECH, letting third-party Android apps adopt the standard. The release also enforces Local Network Protection permission prompts, enables Certificate Transparency by default, and lets carriers turn off 2G by default to prevent downgrade attacks, rogue base stations, and SMS blasters.
