If anybody here is using gnome instead of KDE, there is "GSConnect" that allows you to use your current desktop environment with KDEConnect on your android mobile phone.
In a similar vein, I am not on Gnome or KDE but have been using the basic kdeconnect functionality, such as sharing clipboard and transferring files, through kdeconnect-cli quite happily. It comes with the standard kdeconnect installation I believe.
