Hello,
I save in my application the last used path.
If the last used path was on the smartphone device, than the path is like this:
::{20D04FE0-3AEA-1069-A2D8-08002B30309D}\\\?\usb#vid_04e8&pid_6860&ms_comp_mtp&samsung_android#6&17bddceb&0&0000#{6ac27878-a6fa-4155-ba85-f98f491d4f33}\SID-{20002,SECZ9519043CHOHB01,31901024256}\{00DA0091-00D3-00F9-0901-01010E01C900}\{011B00C0-0114-013A-0901-01010E01C900}
This path I can convert to ITEMIDLIST and if the smartphone is connected I can open the last used path.
It works fine in all Windows versions except Windows 10 1703.
I have found that after removing "SID-{20002,SECZ9519043CHOHB01,31901024256}" from the path all works as in older Windows Releases.
I think it is a bug in the release 1703.
Could you please report the problem to the right Microsoft people.
Thanks,
Eric
