Hi,

I have a question about the Nikon WMU app (Wireless Mobile Utility) for
Android.

How does one close the app?

I can't, it stays in the notification area of the phone. I know I did
exit the app in the past, but today I can not find where. It was
somewhere in the menu.

I had the same problem with Tidal, but now that is fixed in a new
version.
You can go to the list of applications, Select WMU and then do a
"forced stop" (translated from norwegian, do not know what it is in
english). It could make the app behave strange, not sure if Tidal did
that.
