Transferring files between devices has always been a little annoying, but features like Android Beam made it easier: Just hold together two NFC-enabled devices (Android 4.1 or later), and you can transfer files across a Bluetooth link. It’s a neat trick, but transfer speeds are capped by Bluetooth bandwidth, and file type support is limited. Luckily, however, most Android devices also support WiFi Direct, even though Google's stock apps don't make use of it.

The SuperBeam app facillitates device-to-device file transfers at warp speed—even 45 Mbps. Ah, the wonders of Wi-Fi.
WiFi Direct is exactly what it sounds like: a protocol that can create a direct connection between two devices via Wi-Fi. You just need an app to make use of it, and there are several in Google Play. SuperBeam is probably the most powerful, and it has a free version. To get a transfer going, you just share files to Super Beam (or whatever app you've chosen to use) and tap phones. WiFi Direct allows you to queue up multiple files in a single operation and the transfer rate can easily exceed 30 Mbps. It's fabulous for sharing large videos or images.
