@gabrielonwueje this "My phone vibrate" is normal behavior. It is supposed to do that. It most commonly does it when you have a defective screen. By this "charging pot is not functioning also" I assume you are saying that your phone does not charge.
For the power situation I suggest you start of by using the Samsung flowcharts.
