I know i must have clicked something I tried uninstalling the most recent apps that I installed, too. S8+ on Verizon.
When I press it, it vibrates, but that's all, as far as I can tell. Also the black part will turn blue.
i got it for the first time today, same situation. However, i do NOT want to do a factory reset, and would prefer to avoid returning the phone. So i uninstalled some recently installed crap apps, will see what happens
That's good to know... I just have a "trigger" in my car... Loses its benefit if I am going to settings every time I get in my car, just to enable nfc. Might as well just enable Bluetooth and be done with it
