I have a GS20 Ultra that I got from t-mobile. Had it since launch. After the September 30th Security update my device has not been fast charging or super fast charging. I've tried the out of box charger, as well as several other chargers and cables, no luck. I've tried restarting the device, disabling and then renabling fast charging, depleting the battery to zero and then charging to 100% while it was switched off, and even tried safe mode. I cannot get Fast Charging to work at all.
I posted to reddit about this and I was told similar incidents were reported on this forum following the update but I can't find any of those aforementioned posts.
Anyone experience the same and found a fix? I don't want to facotry reset or send my phone out anywhere.
