I came across to this in other rom's thread:
"Sensor fix
Hey i found the Problem about sensors
Please try to move this file (vendor/etc/sensor_def_qcomdev.conf) to system/etc and test Sensors again after a reboot."
I have tried to copy that using file browser with root access. It could not copy for me is there any other way to do it ?
Can confirm this worked. I have sensors multitool app installed. Had 3 sensors and now all are recognised by the app. Auto rotate working again. Make sure your file manager has R/w access and not just R/O. For root explorer it's at the top of the screen.
