> Banking apps (e.g. Revolut) block GrapheneOS actively and many other apps too.

You've misunderstood something here. Revolut doesn't "block GrapheneOS actively". I'm running Revolut and most of my banking apps on GrapheneOS right now.

In my experience, there are two major categories of incompatibility:

- High levels of Google Play Integrity checks: app only works on releases of Android that have been allowlisted by Google. The only app that does this for me so far is McDonalds.

- Commercial root detection APIs: some of GrapheneOS' security features like "Secure App Spawning" trip root detection heuristics. This is the kind of incompatibility I usually run into for banking apps. You can disable individual features on a per-app basis these days to get around this.
