I just saw following news, now that is disappointing, I am always concerned about unwanted application reading my data. I mean there are many application who access your information without actually any need. Now google has removed to block it from latest version.

Google has removed an experimental privacy feature from its Android mobile software that had allowed users to block apps from collecting personal information such as address book data and a user's location.

The change means that owners of smartphones using Android 4.4.2, the latest version of the world's most popular operating system for mobile devices released this week, must provide access to their personal data in order to use certain apps.

May be we can ditch Android and move to windows phone.
