Google is introducing a feature in Google Messages that automatically detects and blurs nude photos sent to Android devices, displaying a sensitive content warning before explicit images can be viewed. This feature includes options to block numbers sending inappropriate images and alerts users when they attempt to send or forward such content. Users can enable sensitive content warnings in the Google Messages settings, while for users under 18, the feature is automatically activated. The detection processes occur on-device using Android's SafetyCore technology, ensuring user privacy and security. The feature is currently being tested on select Android devices running the Messages beta and does not extend to videos.
