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.
GrapheneOS, and other non-OEM OSes, do not. It’s kinda the whole point of the article/OP I linked.
Have you tried playintegrity fix?
Nope, nor do I intend to. GrapheneOS frowns upon rooting and modifying the system as it typically widens your attack surface. I’m not using a secure OS then going around to purposefully make it less secure.
