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.”
Apple had it report suspected matches, rather than warning locally
It got canceled because the fuzzy hashing algorithms turned out to be so insecure it’s unfixable (easy to plant false positives)
