Google is adding new network security protections in Android 17 to improve connection privacy, including support for Encrypted Client Hello (ECH), stronger local network controls, and default Certificate Transparency. The update also helps reduce exposure to 2G-based attacks and makes it harder for ISPs and Wi-Fi operators to profile users’ browsing activity. #Android17 #EncryptedClientHello #ECH #CertificateTransparency #Jigsaw
