I just switched from XFCE+Openbox to KDE Plasma.
When I connect my phone (Asus Zenfone 5Z/Android 10) to my PC via USB, the KDE Device Notifier (running in the system tray) keeps popping up and disappearing. This happens too quickly to even see what the options are. At the same time, my phone continually switches modes between charging and running off battery power.
Most of the time, I just want to use my PC's USB port to charge the phone. Sometimes I would like to transfer files between the phone and PC. But since the typical use-case is just charging, I'd like KDE to do nothing. I can't seem to figure out how to prevent the annoying/useless behavior described above, and how to tell the system to just let the phone charge.
