Google will roll out an improved version of Nearby Share for Android users over the next few weeks. This is essentially the Android implementation of Apple’s AirDrop, so you can quickly send files from A to B when the users are nearby.
Google has put a lot of work into it over the past few years, making Nearby Share a viable solution for many. So far, it was only possible to send files to one person, but now you can gradually select the users before sending them.
