> Why? GrapheneOS restricts camera and biometric APIs. A scan that works on stock Android can fail in a loop on GrapheneOS. The repeated failure isn't fraud. It's a technical incompatibility. GrapheneOS is fully compatible with Android apps using the standard APIs. Apps with memory corruption bugs happening in regular use are usually incompatible with it when the full exploit protections are enabled for user installed apps. However, it can be worked around with the per-app compatibility toggles. The reason apps like this are sometimes incompatible is because they use the Play Integrity API to ban using an OS / device not certified by Google. Some use similar mechanisms to detect users not using a Google Mobile Services OS. Other than that, all apps are compatible with GrapheneOS in practice. When apps aren't compatible even with the per-app compatibility mode toggle, it's usually deliberate. We're gradually working around these deliberate incompatibilities from apps trying to detect a non-stock OS. It's getting better but it takes time. We don't have a non-regulatory solution to long term compatibility with services enforcing the Play Integrity API but we can work around what apps do themselves to ban alternatives and are making quick progress.
