Can be a charging cable fault change it. If the problem persists.
Then you are having trouble with your charging slot. Yes the hardware charging jack.
It might have been oxidised and thus preventing a proper flow of current.
Your both problems refer to the same cause. Either the charging cable or the (hardware) charging jack. Replace either of them and you are good to go again.
And secondly Samsung DONT block any NonSamsung cable. Even in many cases other cable are found to work more smooth and efficient with Samsung phone as compared to original Samsung cables.
