Android 17 adds ECH support to make web browsing harder to track
Google introduces ECH support in Android 17 to enhance privacy and security for web browsing.
Intelligence analysis by Qwen 2.5 (3B)
Google's Android 17 update includes ECH support, a privacy standard that encrypts TLS handshake metadata to protect user data.
ECH is like a secret code that hides where you go on the internet, so your internet service provider can't see which websites you visit.
