@Blaaland: That's strange. When you connect your charger, does the A70 charge as expected? Can you try clearing the USB port of any dirt or debris with a soft brush (if applicable), then press and hold the Volume Down and Power buttons for around 10 seconds until the phone restarts, to see if this helps? If you open the Samsung Members app and go to Get Help > Interactive Checks > USB, and follow the on screen instructions, does this return any errors?
