Just for the record, which OS version are you running? After difficulties with the Fingerprint sensor, did you update to C.059?
Did you send your phone in for repair?
Charging problems usually come from cable, contacts (in plugs and sockets), charger, USB port, components on main board (motherboard). Below are some suggestions
- Cable: if possible test using another cable.
- Make sure the contacts of the cable connectors, USB port and charger USB port are clean. Use a wooden or plastic toothpick, very delicately to remove dirt and fluff, then the small aperture tool of a vacuum cleaner, or a compressed air can to finish cleaning.
- Check the charger and test with a different one, preferably 1A (5W) or 2A (10W). I’ve seen a cable work with one charger but not another, and a charger work with one cable and not another, so try combinations, if possible borrowing from family or friends.
- Check the Fairphone Angels map to see if there’s one near you who might be able to help, for example loan of a USB port for testing.
