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.
Use Total Commander with WLAN-Plugin on the phone. Total Commander can share files via Wifi that you download via Browser or connect via sftp

I assume both devices are in the same WLAN.
