Android 17 quietly hardens your phone with four security upgrades
Android 17 adds four security-focused changes: per-app memory limits to curb memory-hogging apps, a default ACCESS_LOCAL_NETWORK permission to curb silent local-network scans, stricter rules on dynamic code loading to block post-install malware, and Certificate Transparency enabled by default to improve TLS verification (with opt-out options for apps or domains). These improvements aim to boost reliability, privacy, and trust with minimal impact on most apps.
