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.”
Oh right, maybe I noticed because of Storage Isolation, that’s an app which allows you to restrict folder access of other apps, and it prompts me to select actions for every newly installed app. So it casually prompts me whenever google pushes a new, hidden installation.
i believe this application hides in different ways on different devices and maybe it is also different by regions making it even worse to detect and explain to someone else. So, i wouldn’t be surprised if you told me you found it in a different way than how it was explained in my comment.
