Older, incompatible apps still default to asking for permissions at install time. There are two problems with this - first, I suspect most folks won't know that you can go back and turn those off. That's a relatively new feature, and not really something people will explore on their own. . Second - if it's an app you already installed that has required new permissions, that app can run (via BroadcastReceiver) when it is updated and before you have a chance to alter the fine-grained permissions. Separately, the interface for managing fine-grained permissions in Android is weird. You get most of them in one place, but then it seems you have to check a couple of other places for 'special' permissions? edit: never mind this - it seems like the old version is the one that will get notified, and the permission change only applied ot the new one.
