Is the device Rooted / Not rooted : not rooted
Update process was ok. 
Again the known “reboot”. Today I felt a vibration and looked at the phone -
not possible to enter with biometrics it just went to the pin entering screen.
It looks like not really solving the “reboot” problem, it changed…
see here my last post v2.4
Also the “camera not connected failure” in dark environment is there - reproducible.
Flashlight mode at “no flash” or “automatic flash”,
it shows a short message
keep your device steady during auto night
Then if you take the photo it shows the dialog
