Google Play hides app permission changes in automatic updates
Google has changed how new app permissions are applied when updating Google Play apps. Previously, automatically updated apps displayed explicit details and required user confirmation when a new version gained additional privileges. Google Play no longer displays the addition of new privileges if a user has previously accepted any other permission in the same category as the new permission. This makes it possible for an app to sneak in permission changes without the user realising making the Android platform less secure.
It looks as if it is trying to know more about you than Google itself ...
Anyway, I really wish vanilla Android would allow find tuning of the permissions. If I remember correctly, this ability was there at some point for a short period of time in 2013 and then quickly removed (found it: http://www.osnews.com/story/27469/Google_removes_vital_privacy_feature_from_Android).
