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.
You can fix most apps with the Play Integrity Fix module and denylist. You might have to hide the magisk app too. It doesn’t get 100% of them though, I still can’t figure out how my bank app is catching it. Plus I’ve had RCS stop working with that setup, so I have to keep it disabled to avoid missing messages
The apple music app checks for a specific binary. Could be something like that.
