When F-Droid installs an app and sees the GrapheneOS sensors permission it aborts: Support SessionInstaller on GrapheneOS with custom sensor permission (#2828) · Issues · F-Droid / Client · GitLab
there are already two pending fixes:
- Don't change installer if APK permissions don't match (!1410) · Merge requests · F-Droid / Client · GitLab
- Fix permission comparison (!1413) · Merge requests · F-Droid / Client · GitLab
This was an issue for DivestOS too back when I included the PrivExt: News - DivestOS Mobile
