AI Summary

The Android 17 update introduces several privacy‑focused networking features. It is the first mobile OS to support Encrypted Client Hello (ECH), which conceals destination domain names in TLS handshakes. The update also enforces stricter local‑network permissions, enables Certificate Transparency by default, and adds a telecom‑controlled switch that blocks connections to potentially malicious 2G access points. These changes aim to reduce network snooping and prevent SMS‑related abuse.
