Disabling server does not disable GPS reporting
After registering the device to the server and verifying it works (hurray!), I disabled the toggle for the server while leaving the GPS/CELL toggles on. During the server's typical enabled use, the GPS would be toggled on, if off, to send data to the server. However, this behavior is still happening when the server is disabled - GPS is still being turned on (though I'm not sure if the coordinates are actually being sent).
It appears if a user disables the GPS/CELL toggles at the bottom the auto-on behavior finally ceases.
My suggestion: If the server is disabled, make the GPS/CELL toggles disabled (greyed out) to user input so that they are conditional to the enabling of the server. However it looks like a bug, as disabling the server should also prevent the GPS from turning itself on periodically to report.
