Per one tech forum this week: “Google has quietly installed an app on all Android devices called ‘Android System SafetyCore’. It claims to be a ‘security’ application, but whilst running in the background, it collects call logs, contacts, location, your microphone, and much more making this application ‘spyware’ and a HUGE privacy concern. It is strongly advised to uninstall this program if you can. To do this, navigate to 'Settings’ > 'Apps’, then delete the application.”
Google photos has been "searchable by name" for years now. Tell it the name of a face in one photo and it can go search (pretty successfully) through all your photos for other photos containing that person. And, of course, once told, it never forgets.
