ran into an issue today; the phone reboots automatically after all system updates but android couldn't be loaded fully as it boot looped after I entered my sim pin. grapheneOS recovery said that my data may be corrupted and I had the choice between "try again" or "factory reset".
I managed to turn the device off and entered recovery via power and volume down, took a look at the logs and then restarted the system, boot loop is gone now and everything seems to be working fine. any ideas? I have now deactivated the automatic reboot option as I now want to control when I restart my phone.
