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.”
If you freeze via non-room methods, updating the apk will re-enable it. So it’s the same situation as just removing the apk–it’ll basically re-enable itself.
I’ve never had an app frozen through ADB get auto-updated by the Play Store or Google Services and get re-enabled because of it. An app with an update available will even disappear from the Update list if disabled, and in order to update it you have to enable it first.
Freezing an app in an non-root fashion doesn’t do anything special. It’s moved to a different location and is effectively “removed” from a runnable state. The OS shows it as disabled/removed, but the files are still there. Newer versions of android (14+) will recognize applications it thinks are necessary (like this one, from Google) are moved/disabled and will pull a new apk during the upgrade process. It effectively re-installs the app.
By upgrade, do you mean OS upgrade?
