Android Auto support for our sandboxed Google Play compatibility layer has been merged into GrapheneOS and should be available in the next release. It’s currently going through final review and internal testing leading up to being able to make a public Alpha channel release.
The implementation uses the compatibility layer to eliminate most of the special privileges that are usually required. It provides 4 permission toggles for enabling different access for wired Android Auto, wireless Android Auto, audio routing control and phone call control.
No special access is granted by default. We’ve made subsets of the standard privileged permissions for these toggles for granting only minimal required access. Wired Android Auto is close to working with 0 special access required but not quite so it still needs a toggle.
I’ll check that out later I guess. The stock google work profile functionality didn’t work when I started my current job and the only thing I could find on the topic seemed to imply that it was incompatible with graphene differences to standard android. Also the work email specifically requires work profile to allow me to sign in via app instead of browser.
