I have registered this account just for asking about this problem. Well, this problem was already happened about half of a year ago. It couldn't charge only a few times on that time so I didn't pay attention to that. After some time, this problem became more serious and I can't use any charger including the Tablet 3 and other Samsung phone (which is more like a piece of crap by its history). I've tried to find any solutions including put the charger in the fridge and wait for a whole day and yet it coudn't fix this (lol that's funny to try this ridiculous solution). Hope someone can provide more effective method to fix this. I'll appreciate for that.
