For the past few weeks my Galaxy Tab S3 has been charging from a regular non-fast charging capable charger. When I plug it into a fast charging cable it does not charge at all. Is this a hardware or a software issue?
first without knowing too much about your situation I would check to make sure that the cable itself is not at fault. Try using a different fast charge cable and see if it works with that one. Narrow it down . I hope that helps and you get to fast charge your phone in the future
