I have (eventually) had success on my brand new SM-G900V. i did have to jump through some hoops though...
I installed UPSM Manager, selected apps, saved, rebooted, entered upsm, no joy... only default apps listed.
After reading this whole thread, and trying a few tricks listed here, I had succcess only after I went into:
settings->applications->application manager->All(tab) and cleared data for both EmergencyManagerService, and EmergencyProvider.
Props to koko115 for the idea in Post 93 of this thread
And BIG Props to Xperiacle for this great utility!
I hope this will help others, please let me know
