I'm looking for suggestions on what may be happening when I leave Rpi 3B+, Venus OS 3.10~38 unplugged for several days. This has happened twice now. What I'm finding is my wifi tether and hdmi calibration settings are removed. Specifically, /data/var/lib/connman/settings and /etc/pointercal. I've had to reconfigure the wifi tethering and hdmi calibration.
What's really strange is I've shutdown and restarted the Rpi and the settings are preserved. This seems to only happen when unplugged for several days (still experimenting with time interval).
Firmware online updates - disabled. I do have Setup Helper and Shutdown Helper installed.
I'm considering copying backups of the above files on startup.
Thank you
Don
