I currently own a Galaxy s20 and suddenly the NFC will not work when trying to contact less pay for goods. The app opens correctly and when trying to pay pulses like it should but does nothing when held against the reader. So What I've notices in the pull-down menu when trying to toggle off and on the icon is shaded rather than bright and I cannot tolle off or on ( nothing happens when pressed) When I hold the icon it takes to the app screen and still cannot turn it off. I've cleared cache and data with no luck. Last resort I factory reset the device and this worked. I could use NFC and toggle it off and on until today the original problem above has occurred . Please help.
