Overview

• Mobile network security page now alerts users to unencrypted or suspicious cell towers, signaling potential Stingray-style surveillance.
• Users can enable a network notifications toggle to receive alerts in the notification panel and Safety Center when network encryption status changes.
• The 2G network protection switch allows users to turn off 2G connectivity, blocking downgrades to older protocols exploited by IMSI catchers.
• Because the feature relies on Android’s Radio HAL 3.0 drivers, it will first appear only on devices that ship with Android 16, including forthcoming Pixel 10 models.
• Phones upgraded to Android 16 without the required hardware support will not display the Mobile network security page or its controls.
