Fast charging not working properly
A week ago, I received my galaxy s8+ as a pre-order. The phone worked properly, until it didn't charge fast anymore... everytime I plug in my charging cable (the same cable and adapter that came with the phone) a pop-up appears saying that it can only charge slow and I had to be sure that the charger was plugged in properly. I then tried cleaning the port with a thin plastic stick. This worked for about an hour, whereafter it stopped working. Until now, it still takes 6 hours for a full charge..
Does anyone know how I can clean the port properly, without damaging it?
Thanks in advance!!
