The Galaxy S10's fancy LED case disables the phone's NFC
The LED cover has tiny LED lights embedded on the back, which can be configured to display various things, from emoticons and a timer whenever you’re using one to take a picture, to a so-called “mood lighting”. Overall, it sounds pretty cool and we’re sure many will enjoy the interactiveness it offers besides the protection of your precious new phone.
Of course, the circuitry embedded in the case to make the LEDs work is the culprit to blame for this unfortunate drawback. Whenever power is running through it, it's likely interfering with the NFC signal, so for safe measure, Samsung decided to disable it completely.
To be fair, that’s really only a drawback if you use NFC often and the hassle of turning the cover LEDs on and off would be too much. But from our observations, most people aren’t that deep into an NFC ecosystem yet. For those that are, however, this means they’ll have to rely on a cover without mood lighting. What a bummer!
These cases aren’t available for purchase yet, so there is a slight chance that the final version will allow both the LEDs and NFC to work at the same time, but we wouldn’t bet on it.
