Question: Is There a quicker way between Ubuntu and my android to send files instead of Bluetooth or usb cable? Am I aware of quick share that uses wifi. can this be done? I'm using a Samsung galaxy note 10. I'm not sure if this has been asked before.

Answer: 
Install `kdeconnect` on your phone...

Install `gsconnect` on your computer...

Pair them. Enjoy.
Try [KDE Connect](https://kdeconnect.kde.org/) it's installable from Ubuntu software store or command-line apt (and of course the KDE Connect app from Android store).

I just use it for ocassional file transfers but it has loads of other features if you want/need them.
