LED cover features
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.
- Mode lighting: When Galaxy device is facing downwards, a light show is presented with the LEDs.
- LED notification icons: You will get notification icons on the back when a notification arrives.
- Camera timer: If the timer for the rear camera is turned on, the countdown will be shown on both the screen and the cover.
- Emoticons for the rear cameras: When you open the camera app, and the rear cameras are active, a LED icon you chose will be shown on the back cover.
Note: Supported functions may vary depending on the type of genuine LED cover.
What is NFC?
NFC stands for “Near Field Communication” and, as the name implies, it enables short-range communication between compatible devices. NFC technology allows users to make secure transactions, exchange digital content, and connect electronic devices with a touch. NFC transmissions are short range (from a touch to a few centimetres) and require the devices to be in close proximity.
NFC is the technology in contactless cards and the most common use of NFC technology in your smartphone is making easy payments with Samsung Pay. NFC can also be used to quickly connect with wireless devices and transfer data.
