Screen shot from GNOME Nautilus

When trying to access files on my Android phone (Huawei P10 Lite) via PTP
protocol, the device name appears in the navigation bar of Nautilus, but when
clicking on the device name, an error pops up, and no files are shown.

Here is my guess of related syslog messages:
gvfsd[3384]: Device 0 (VID=12d1 and PID=107e) is a Huawei P9 Plus.
gvfsd[3384]: Android device detected, assigning default bug flags

The very same hardware worked with Leap 15.1!
