What wireless charger do u use ? I've just bought a samsung one tried doing the test on it but can't use the super fast charger plug so keeps saying there's a fault on it 🙃
@Annie989: From what I can gather, this Wireless Pad supports wireless charging at up to 7.5W, however Fast Charging 2.0 on your Galaxy Z Fold 2 requires support for 10W+. With this in mind you might wish to consider the Wireless Charger Duo Pad, which should allow you to use the Fast Wireless Charging feature on your device. To find out more, please check the link below. In the meantime, please disable the Fast Wireless Charging option in Device Care > Battery > Charging, as you may still be able to establish a regular wireless charging connection with your current pad.
