Permission Master

Permission Master is a module for Xposed (which you must have installed in order to use this app) that allows you to disable permissions for any of your device's apps.

One of the most interesting things you can do with Permission Master is look at the permissions your apps have. You can look at individual apps or search for ones that have specific permissions. For example, you can look at the permissions Twitter has, or see which the apps can read your text messages.

Denying permissions using Permission Master is very simple. Just click on the permissions you want to disable. In less that a second these permissions will be crossed out, meaning they've been denied and can't be used anymore by the app.

Permission Master is an excellent supplement for Xposed users. And many other apps require more resources than this one.
