The functionality provided by Google's new Android System SafetyCore app available through the Play Store is covered here:

Neither this app or the Google Messages app using it are part of GrapheneOS and neither will be, but GrapheneOS users can choose to install and use both. Google Messages still works without the new app.

Als Antwort auf GrapheneOS

also probs good to note that there are other linux based operating systems for smartphones that are not derivatives of the AOSP are available such as:

- Ubuntu Touch by UBports
- Sailfish OS by Jolla
- postmarketos
- Mobian
- Manjaro arm
- Archlinux arm

if i remember correctly Ubuntu Touch and Sailfish OS are the most "usable for day to day" but idk if thats changed in the past like 4 years since i looked into them

but android is still just a highly customised linux distribution for smartphones
