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.
Do you pass play integrity?
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?
