Something odd is going on with the my S4 running Android 4.4.4 (the latest playstore app works on the S7 Android 8.0.0)

On the S4

With the 2.1.1( app built from source a "Choose app for the USB device" dialog comes up with Subsurface-mobile in the choices.
With the 2,1.3( this dialog does not come up.

2.1.1( built from source can access the ftdi device when run from the USB choose app dialog.
2.1.3( from the app store can not access the ftdi device and gets the permission error.

I'm still trying to figure out what is going on.
