writes "An update to the Google Play store now groups app permissions into collections of related permissions making them much less fine grained and potentially misleading for users. For example the SMS permissions group would allow an app access to both reading and sending SMS messages. The problem is that once an app has access to the group of permissions, it can make use of any of the allowed actions at anytime without ever informing the user. As Google explains: "It’s a good idea to review permissions groups before downloading an app. Once you’ve allowed an app to access a permissions group, the app may use any of the individual permissions that are part of that group. You won’t need to manually approve individual permissions updates that belong to a permissions group you’ve already accepted.""
