TL;DR
- Efforts like Graphene OS face increasing pressure from apps that refuse to run on non-standard Android.
- The custom ROM project characterizes Google’s approach to device attestation as incomplete and flawed.
- Graphene OS is prepared to take legal action if Google won’t let it pass Play Integrity checks.
Yes, I have Google Plays Services, Google Services Framework, and the Google Play Store installed, which are all sandboxed. MicroG isn’t supported by GrapheneOS.
