yore I am running GrapheneOS (build 2024072800) on a Pixel 6a with a Verizon physical SIM, using the built-in Phone app.
If I open the Phone app and tap on the ⋮ and then Settings, "Calling accounts" is not an option. If I tap on "Calls", "Calling accounts" is an option, but what I have then is:
- Settings (tapping on that does nothing)
- Make & receive calls (tapping on that does nothing)
- Make calls with [Verizon]
If I tap on that last one, I get a pop-up that says:
Make calls with
[] Verizon
[] Ask first
Cancel
I am not able to reproduce going from "Settings" to "Calling accounts", nor am I seeing "Additional settings" including "Caller ID". Are you using the GrapheneOS dialer?
