Does anyone know about this app?
I also got that and was little afraid of updating, worrying if Samsung trying to sneak some security update for Knox, or root discovery etc.(I'm stock rooted). But it seems to be internal driver related to data exchange over networks, possibly updated due to new hardware like VR or S-watch. I updated it now, so in case I buy Samsung watch or some other new hardware in near future, I won't go crazy wondering why it doesn't work, since once you decline the update, usually doesn't come back anymore.
