I am looking for help before sending my phone to maintenance service. All of sudden my phone stopped charging from a socket. The phone is charging (bolt showing, charging screen showing etc) but actually it won't charge at all. We tried different chargers (got originals from Samsung and HTC) and different wall sockets. Nothing helped. I was able to charge it from USB in a car and USB from laptop (of course instead of 2-3 hours to fully charge it took over 5 hours but it works.) Also charged it from powerbank. I purchased new battery but still got the same problem so the glitch is not in battery or socket charger ... any ideas?
