The USB C port on my Note 8 has the following characteristics:
1) Allows slow charge over USB ONLY when the phone is switched on.
2) Does not fast charge when phone is on. the phone will beep and show fast charging, but immediately beep again and switch to cable charging.
3) Does not charge at all when phone is off (ie no charge LED or display to indicate charge level).
4) Does not allow phone to be tuned on whilst cable plugged in AND power applied (through wall socket, PC or powerbank).
5) Will randomly tell me that there is moisture in the port (there is not). This notification appears more when using certain cables.
6) Only if the battery is completely dead will it charge via USB when switched off.
Points 1-5 i have tried both the original wall plug and charging cable along with other wall plugs and cables. Point 6 i happened to be using my Honor wall plug and Honor USB C cable as that is what i had to hand. Its interesting that it charged - almost as if bypassing some checks that the phone does even when off??
What I have done:
A) Wiped DAVIK partition.
B) Cleared storage associated with USB settings.
C) Cleaned out the USB port on multiple occasions using 99% isopropyl alcohol, using toothpicks, cocktail sticks, compressed air. I can not see any lint or debris in the port. I can see the rows of pins in the port though and I cant see any damage (though this is obviously limited)
D) Check that Fast charging is enabled - i have disabled and re-enabled this as some YouTube videos suggest.
E) Used the same original and aftermarket cables on my Wifes S8 and verified that they are able to fast charge her device.
What i think:
At this point, having gone through many guides here and elsewhere, looking at YouTube videos all i can think is that I have a hardware fault, possibly related to the moisture sensor that is erogenously flagging up moisture sometimes. Some cables, such as the Connector for my DJI Mavic Pro controller constantly trigger the moisture sensor, followed closely by the original Samsung cable. My Wife who has an S8 can use these same cables with no issues. The only solution i have not tried is a factory reset because im not convinced it would work as the phone does not charge when switched off.
Over to you guys, i know its a long post but rather everyone have the full facts up front.

. What i dont understand is why it is worse with certain cables (for example the cable from my DJI Mavic Pro Controller
