Up until very recently, I thought that USB C was symmetrical, that it could be plugged in either way and it always acted the same.
I now have two phones that both behave in the same manner. (HTC U11 life and Sansumg Galaxy S8) When using the factory charger and cord, connecting the plug in one orientation causes the phone to slow charge and flipping it over causes the phone to fast charge.
Was my assumption wrong to begin with or is something else the matter?
