This notification comes from an app that is designed to tell a remote user where you are located. That was enough to spook me.

I dismissed the notification, deleted as much data from Samsung apps as possible, and turned my phone off.

Rough moment to be a Samsung executive. They're just about the only top smartphone manufacturer that doesn't manufacture the vast majority of their handsets in China so presumably they are in position to take some market share from the competition. Yet today we are seeing some fear about contagion in SK, and this very strange notification that -- benign or not -- is going to scare some users (e.g. me). I for one would like to see a formal statement made to the public.
