title: react native navigator.geolocation.getCurrentPosition issue
body: <p>I'm developing an app where I need to know user's current location. For now, I'm using <code>navigator.geolocation.getCurrentPosition</code>, but it's not convenient. It doesn't always get the current location, again it doesn't work on all devices with same parameters. 
  So, I want to know is there any other library which is more convenient or anything I can do in the current method which will get the current location without failing?
  Any suggestions will be appreciated</p>
