I can confirm the bug also with libmtp9 1.1.17 and a Samsung Galaxy A3 (2015, A300FU). Is there at least meanwhile a solution independant of libmtp and a bit faster than installing a FTP server on my phone?
$ sudo apt-cache policy libmtp9 libmtp9: Installé : 1.1.17-3 Candidat : 1.1.17-3 Table de version : *** 1.1.17-3 500 500 http://ftp.fr.debian.org/debian sid/main amd64 Packages 100 /var/lib/dpkg/status $ sudo mtp-detect libmtp version: 1.1.17 Listing raw device(s) Device 0 (VID=04e8 and PID=6860) is a Samsung Galaxy models (MTP).
