Bug 409079 - Cant open filesystem on Android device

Can confirm an issue with accessing the Samsung File system from the desktop. Desktop version: 1.3.5-3 App version 1.13.5 (24.nov. 2019)

I gave kdeconnect adb access rights while connecting through adb/usb and now it can access the android file system via wifi and via usb with dolphin perfectly fine.
So guessing it is a "security fix/restriction" by android. 

If that matters, the phone is a SM-G930F (S7 Galaxy) - Android version 9.
I got the logcat running while it does it:

Comment 8 Axel Braun 2020-02-09 09:34:16 UTC

KDE Connect release 1.4-1.1  and App version 1.12.93 still show the same issue
@Jack - can you describe how you gave access via adb? Does it only work for USB connections or as well via Wifi?
