ironbone opened a new issue #151: iOS watchPosition problem 
URL: https://github.com/apache/cordova-plugin-geolocation/issues/151
 
 
   # Bug Report
   
   ## Problem
   The function in subscribe in watchPosition is not called when the user does not touch the screen (or interact with the application) even if the position has changed
   
   ### What is expected to happen?
   Every time when the position has changed the function should be called.
   
   ### What does actually happen?
   When subscribing to  the watchPosition the  event function is first called 2-3 times. Then during the application stay in the foreground the event function is not called. There are no errors.
   
   When the user touch the screen (sometimes) the function is called. Every time when the application goes to background and return to the foreground the function is called twice.
