This Galaxy S20 accessories guide explains the unique features of the Galaxy S20 LED View cover, shows you how to use the cover (including assign and customise LED cions, accept and reject calls, control music), answers some questions you may have on this cover. A no-nonsense review of Galaxy S20 LED View cover is also included to help you decide whether this cover is for you.

How does the Galaxy S20 LED View Cover (LED Wallet Cover) work?
LED View cover, which is a successor of LED Flip cover, was first introduced with the Galaxy S7 and S7 edge. Samsung changed the design and materials over the years.
But the fundamentals are still the same.
There is no battery in the LED cover. The LED cover get power through NFC, NOT through wireless charging. But it does affect wireless charging (for safety reasons). When you charge Galaxy S20 battery with a wireless charging pad, the wireless charging will be paused automatically when LED icons are shown. And it resumes once the LED disappears.
The communication between the phone and the cover does NOT rely on the NFC settings. It is hardcoded in the firmware. Even you turn off NFC on your phone, the LED cover still works normally.
So, this is totally different from how S Pen on Galaxy Note devices works. S Pen does NOT use NFC.
The old S Pen (until Galaxy Note 8) does not have a battery. You do not need to charge it. These old S Pens get power from the screen (through electro-magnetic grid under the screen) when you use it.
