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.
Yet I can compile applications that work on Windows XP, and they still work under Windows 11.
It’s not as if Android is some svelte slimline OS where every byte matters. There’s plenty of room there for keeping compatibility with older apps.
