Charging my tab s2 with the supplied cable is not a problem. However that cable has started to split and fray just at the plug end. (not uncommon). So I plugged another micro usb cable into the adapter and started charging my tablet. After 10 minutes I noticed that the cable end plugged into the tablet was very hot. I never had this with the other cable. I thought these cables were generic. Is it a possible cable fault? Thanks, Tony
