I have an S20U Exynos and for now it's doing everything right after the A12 update and February patch .. As for the auto software update, I think in the "Developers Options" is that option...

Go to samsung members app > get help > diagnostics for self test on the hardware parts.
if it doesn't show any issue with the charging port/battery then you can submit error report to samsung members app > get help > error report after reproducing the issue.
It may have messed with the software while updating to A12/UI4.0, major updates can sometimes cause random issues that is often recovered with reboot, cache partition clearing, or in the bit more worse case a hard reset (factory reset)... but I don't recommend doing factory reset 'till the very end.
get support from samsung as much as you can before factory resetting.
