Seriously, I have tested it with 3 other iPhones already and NONE of them can find me! Before you ask, yes, everything has been set up properly! Wi-Fi/Bluetooth/AirDrop itself ALL enabled to EVERYONE with the screens turned on! My phone CANNOT be discovered by any others! In fact, in two iPhone 5's I tested, they were able to detect eachother but could NOT detect my phone! Anyone else facing these issues? I just want AirDrop to work... I'm already on my 3rd 5s and I'd be very disappointed if I had to get my 4th replacement. EDIT: Just sign out and back into your iCloud account. Should fix any issues with AirDrop.
