They’re calling it ‘Nearby Share’ and is already available on some Google Pixel and Samsung Android phones.
Similar to Apple’s AirDrop, ‘Nearby Share’ will allow users to transfer files between devices without rigorous setup and configuration. The transfer takes place using either Bluetooth, Bluetooth LE, WebRTC or peer-to-peer Wi-Fi, dependant on which is fastest based on the phones and environment. It also means that the sharing function should operate whilst entirely offline.
Unlike AirDrop sharing between phone and computer is unsupported entirely, with Google saying that ChromeOS will have the functionality added soon. Unfortunately Windows and macOS users will be left out in the cold and frankly leaves the solution wanting in my opinion.
