Same here, on Kubuntu 18.04, default install: kdef 5.44, plasma 5.12.6.

I cannot copy files from my Android phone or tablet via MTP with a USB cable.
The phone is Android 7.1 and the tablet is 4.1.

If I click the Plasma notification to "Open with file manager" it always says
"No Storages found" even though the phone is unlocked and I had already
selected "Transfer files" on the Android USB dialog. If I close this Dolphin
dialog and the Dolphin window, the phone bleeps a few times as if trying to
reconnect, ultimately showing me the USB connect dialog again where I can
choose "Transfer files".

If I just open Dolphin, without using the Plasma notification, I can browse the
phone, try to copy a file, Plasma says it "Cannot read file /Xperia...",
Android shows the USB connect dialog again. I close the Dolphin dialog, Plasma
says "Copying finished" although nothing is copied.
Sometimes I get a dialog saying "The process for the mtp protocol died
unexpectedly."

If I never touch Dolphin or the Plasma notification and use Kate to open text
files from Android everything works fine.

A dmesg output:
