The ability to command what data applications can access
Privacy breaches by apps are a huge problem nowadays and even if you grant them the limited list of permissions, there will be no guarantee they won’t abuse them. With a customization framework, called Xposed, you can choose what information you allow your apps to access for each of them. When you deny an app the information it wants, it will be either fed no or blank data. However, sometimes you can prevent an app from operating properly by denying it access to critical information so be careful.
