I had a similar problem show up on Lubuntu 16.04 (i386). One thing that SEEMS to work (it actually made a Samsung phone reboot!) is
1) disable the "USB debugging" on the phone; 2) set the phone to Airplane mode (so it doesn't try to make a network connection). In my case, running `dmesg` it seems that Network Manager was trying to set a network connection: [ 1039.598665] cdc_acm 1-3:1.1: ttyACM0: USB ACM device HTH. -- You received this bug notification because you are a member of Ubuntu Desktop Bugs, which is subscribed to gvfs in Ubuntu. https://bugs.launchpad.net/bugs/1314556 Title: Unable to mount Android MTP device To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/gvfs/+bug/1314556/+subscriptions -- desktop-bugs mailing list desktop-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/desktop-bugs
