Do Android Auto and VoLTE / VoWiFi work on Graphene these days? I also remember Google Maps and Uber being extremely problematic

Android Auto is supported on GrapheneOS:

VoLTE and VoWiFi are supported if your carrier supports it.

Google Maps and Uber work fine, provided you install sandboxed Google Play.

Uber, Google Maps, VoLTE, VoWiFi, and eSIM work. You may need to install the sandboxed Google Play Services from the Apps app.

Android Auto is completely disabled as an opinionated security measure.

Google Pay and some banking apps (ones that require Google's Play Integrity API) will not run. GrapheneOS doesn't attempt to spoof these APIs because they are moving towards cryptographic verification [0]. Most apps don't require this check but if they do you are out of luck unless you can get the app developers to trust GrapheneOS's keys.

Note that Android Auto has been supported in GrapheneOS for a while:

I think they work if you install Google Play Services (as a sandboxed app). What doesn't work for me is contactless payments with Google Pay however Google Wallet itself works. But I think that is actually intended and for security reasons.

Google Wallet is usable on GrapheneOS, but Google artificially restricts contactless payment functionality to Google-certified OSes.

It's not a real security check that they're doing, but rather just checking for certification, which is very unfortunate.
