While Marshmallows are soft and gooey, Android 6.0.1 (Marshmallow) is one tough cookie. Marshmallow provides granular security controls that allow you to decide whether an application gets access to particular information. Tired of LinkedIn or Facebook trying to grab all your contacts?
To take a look at these settings, go to Settings->Apps->Application manager. Pick an app and you’ll see a bunch of sliders that let you turn access on or off for that control. Newer app versions directly support the Marshmallow security model. Older apps don’t and may malfunction, but don’t let that stop you from trying out settings that meet your security requirements.
Blackberry has had this level of application security control for many years. It is good to see that Android is now taking application and data security very seriously.
