To me is more comfortable and effective and definitly works better using the AirDroid web extension. I desintall Android apps from AirDroid interface, and move files in both directions.

Connection via USB between Debian and Android smartphone
Re: Connection via USB between Debian and Android smartphone
I have never used pure android (I too, use LineageOS' version of Android) so this may not be the case for google's Android:
When you plug the usb into the computer, default mechanism is charging. It won't show up in the file manager on the computer while set to this..
If you swipe down to notifications, there should be a notification saying 'charging, click to change' or some similar verbiage to that.
If you click it, a pop up will appear with numerous options -> select MTP and you should now see the phone mounted in nautilus (if you're using gnome, for example)
Clicking on the phone name in the file manager will lead you to the android file system and SD card.
