After giving up Android Beam feature from Android Q version, Google will develop another file sharing feature named Fast Share, get the idea from Apple's AirDrop.
Fast Share will use the Bluetooth protocol to 'shake hands' between two devices, then switch to Wifi to transfer data at a higher speed. Users can also set hidden or visible mode with other devices, similar to the current Bluetooth file transfer feature. The operation of this feature is quite similar to AirDrop, when the user selects the file to share, select the device and the device will do the rest.
According to the images revealed recently, Fast Share can work with most mobile devices: Chromebooks, Android smartphones (in this case, Pixel 3), Android Wear watches and even Iphone. There is currently no accurate information on when this feature will reach users.
