Google’s Unannounced Update Scans All Your Photos—One Click Stops It

"Android System SafetyCore’ 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."

If you don't want to navigate android settings you can also simply uninstall it from the Play Store https://play.google.com/store/apps/details?id=com.google.android.safetycore

Additionaly you can install this placeholder app to prevent Google from reinstalling it every time it updates: https://github.com/daboynb/SafetyCore-placeholder
