The geo-tagging logic is severely flawed. The stock camera app will not add the GPS coordinates to the pictures unless there is a wifi connection. The camera app just says 'locating' and does not add the GPS coordinates. This is ridiculous. I cannot even get it to work with a data connection it seems it must be wifi. I don't have a clue what they were thinking. Why wouldn't they add the GPS coordinates to the pictures if they are available and you tell it to? The network connection should have nothing to do with geo-tagging. I really hope this stupidity gets fixed.
