It's rather frustrating. I made sure that my 5s and my friends 5 both have AirDrop enabled to "everyone" and both WiFi and Bluetooth are enabled. I'm trying to AirDrop photos. Neither of our phones show up to the other one. I have already reset network settings as well, neither phone shows up to the other. I have already tried to AirDrop multiple phones, still to no luck. Any clue as to why this is happening?
