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: 
I use [SSH/SFTP Server - Terminal](https://play.google.com/store/apps/details?id=net.xnano.android.sshserver&hl=en_CA&gl=US) from Banana Studio.

It has advantages:

* No USB cables which can be a pain to find at times.
* No teethering your phone to your comptuer or USB hub.
* No bluetooth which many seem to have problems with.
* KDE Connect requires installing application on phone and in Ubuntu.
* SSH client is already installed in Ubuntu.
* Logon with SSH which provides automatic encryption.
* Use SSHFS to mount phone as "normal" partition.
* Automate file transfers with bash scripts.
* Utilize Nautilus (Files) for browsing directories on phone.

Having the phone as an SSH server is faster for me to use but I'm not sure if file transfer over WiFi is faster than over USB cable or bluetooth. A lot would depend on the WiFi speed of your phone and router.
Through cable, you can use the Android File Transfer for Linux, available from snap store:

```
sudo snap install android-file-transfer-linux

```
