Novaliss I get a 'GrapheneOS' notification at startup, that says system_server crashed. If i click more info, I get a log that says at the top crash, and then a few lines down something about sensors. I've been able to save a few logs, other times it reboots itself before i can get there. Sometimes it reboots, doesn't give the notification, but the sensors are clearly not working correctly - if at all.
It is currently in a state of lagginess, slow to wake, when the screen comes on, the biometric scanner is slow to respond. When it is unlocked it seems fine, but still no tap to wake, still no auto brightness adjustment.
I know it COULD be a hardware issue, but the phone was working absolutely fine, until i got the notification to reboot due to OS update, which i did, and it's been dodgy since the moment it rebooted. Coincidence maybe, but, it's brand new as of a week ago so I'm skeptical.
