My charger all of a sudden start to shock. It eletrocated me in two several times. It was a really heavy shock as i shouted and was strongly with my hand to throw away the phone. Aluminum mental case phone is a death traps for phones users But the charger still works fine and It charges phone. I am now scared of touching the phone while it’s on plug, I first of all plug the phone before plugin the charger and disconnect same way. Now i was to ask what is responsible for phone charger to shock. And if the voltage is high why did the phone not get fried up.
You need to get rid of that charger. It clearly has a grounding problem and it will either cause you pain or eventually damage your device.
