Whether you use iPhone, Android, or pretty much any kind of smartphone in between, theres some sort of extremely helpful and convenient technology you can use to quickly send and receive photos from friends. On iPhone, its called AirDrop, on Android its Quick Share, but if you live in the modern world, you know what this is; you want someone nearby to see something, you drop it to them over wi-fi (with some Bluetooth tech mixed in there, I think?).This is a ubiquitous technology now;if youve got the wrong phone settings, anyone near you could drop anything onto your phone. And thus the premise of the new Blumhouse horror movie,Drop!In it, a single mom (Meghann Fahy) out on a first date comes under siege from a series of threatening drops.
