Android Q removes support for Android Beam
Android Q will add many new features, but it will also take away an old one Android Beam. Theres no native replacement on the horizon, but similar functionality can be achieved by apps (including Google Files).
For those of you who dont remember which were guessing is almost everyone Beam is a peer-to-peer file transfer technology. It uses NFC to do the handshaking and Bluetooth to send the data.
The Google Files app has the ability to share files locally over Wi-Fi. This promises speeds up to 480Mbps, well in excess of what Bluetooth can do. The initial connection is set up over Bluetooth, similar to Apple's AirDrop and the transfer is encrypted with WPA2.
Beam was first introduced back in 2011 with Android 4.0 Ice Cream Sandwich. Apple released AirDop that same year with iOS 7 and by the looks of it, the Apple tech has found more success.
