I recently bought samsung A70s phone. The original fast charger that came with the box is being used by me. When I remove the charger from one wall charging point and plug into another, it doesnt charge phone. Sometimes the charger works. Sometimes it doesnt. So now I keep the charger plugged into one point only at home. Phone chargers properly when I use any other c type charger including when charged from laptop. Is there any solution for this? To me it seems like the charger is defective!?
