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.”
caller id is the thing that tells you the number. it isn’t cheap to forge, but it’s the only way a scan could reasonably effect anyone with more than half a brain. there is never a reason to send information to an unknown SMS number, or click on a link from a text message from an unknown number.
