Android 6.0 has some good new features but the best feature is the new permissions model.
It has an iOS look and feel to it. Well-crafted applications can now ask for permissions as they are needed, rather than all at once during installation.
Older versions of Android Apps will still ask for numerous permissions up front, but Marshmallow will allow for iOS-like granular control.
But if for example you don’t want to use Facebook’s Find Friends feature and don’t want the Facebook app to access your Contacts. Just turn it off. Test the features by denying various permissions and testing the “necessary evils” that you might have installed on your Marshmallow phone.
