My Note 5 has recently stopped fast charging. I've replaced that cables and even tried using my girlfriends S6 fast charger and still nothing. My girlfriend can still fast charge her phone on my old OEM fast charger block and cable without any problems. I've done some googling and the only advice is to replace the cable and block, but again that isn't the problem. Does anyone have a solution for this or may know where the problem lies? Any help would be greatly appreciated. Thank you.
