SUMMARY
I have two activities: "A" and "B". On "A" I have running Dolphin instance. I switch to other activity, so "B". Now I plug in pendrive into USB socket and get "Device Notifier" opened. After calling option "Open with File Manager" activity is switching back to "A", where Dolphin is running. I expected that in my current activity will be started new instance of Dolphin, because I work on this activity and don't want to switch to previous one.

STEPS TO REPRODUCE
1. Create two activities
2. In first one run Dolphin
3. Switch to other activity
4. plug in pendrive into USB socket
5. In "Device Notifier" click option "Open with File Manager"
6. 

OBSERVED RESULT
activity is switching to this one where Dolphin is running and proper folder opened in Dolphin

EXPECTED RESULT
should be run new instance of Dolphin in current activity and opened proper folder
