Hi
I'm using pixel2, and looks like GrapheneOS got same problem like early versions of Android 8, when i plug in headphones with cable 3,5 mini jack to usb-c (original cable) system recognizes it as charging through usb not as headphones. You need to restart the phone in order to headphones to be detected. Each time headphones are unplugged, system need to be restarted to detect them again.
