Like others reported here, I observe the same problem (slowness) with my Samsung Galaxy A5 and ubuntu-18.04.
I tried Android File Transfer as suggested in comment #10, and it's indeed way faster. That being said, I had to switch my phone to using the "Image transfer protocol" (MTP (or PTP?), not sure what's the actual name in english), and it seems this also sped up access via Thunar. Switching back to "File transfer protocol", the access is again very slow under Thunar. As other complained, this was reported 1 year ago, and apparently no progress?

I have used MTP on 16.04 without problems, but on 18.04 it does not work. When I connect my Android devices (Samsung A5 and Samsung J3) and I try to list directories with many files (e.g. /DCIM/Camera) the window hangs until I disconnect the device. Same issue if I try to post the command "ls /var/run/1000/gvfs/<MTP-FOLDER>". I have installed Ubuntu 18.04 on two different machines - an older HP laptop and a recent DELL laptop - and the issue is present on the all of them. I suspect a defect on the "libmtp". I tried many alternative solutions suggested by the net (e.g. jmtpfs and so on) but anyone worked. That's all!
