If I understand you correctly, you are unable to browse the contents of your Android phone internal storage using
desktop/kio-extras - which are part of this topic - but also
desktop/android-file-transfer, which was last updated two months ago.
usr/bin/mtp-detect from the package
core/libtmp works as expected.
There are too many topics and issues about this, so I don’t know where to begin.
I reopened issue #73, continue there to keep all the information in a single place.
