It's gimped for me because it insists on using an insecure sftp algorithm, so I cannot use the file system browser to transfer files to/from my Android 13 devices. It probably can't access the root anyway. I want to use it for backing up my device files, especially the Android folder.
KDE Connect utilizes SSHFS in order to securely and wirelessly mount your Android device's file system to your computers. You will be able to browse all of the files on your device via your preferred file manager whether that be Dolphin, Nemo, Nautilus, Thunar, etc.
