When using Light control, you cannot read or write NFC tags or share data between NFC devices. According to the message that shows up when you turn on the LEDs of the case, “NFC isn’t available while using Light control”. It means that if the LED functionality of the cover is used, the NFC on your Galaxy phone will automatically be turned off. Therefore, you must turn off Light control of the LED cover to use NFC. There is no LED back cover, and only while using the Light control function, the P2P function and the tag function of NFC cannot be used, so a pop-up message occurs.
