In Android Marshmallow, app permissions are requested as the app needs access to specific content.
When first accessing a feature that requires user permission, you must choose whether to allow permission.
If you allow permission, the app is allowed to access specific features from other apps or view phone info.
If you do not allow permissions, app features may be restricted or won’t work.
Notes
•You can change permissions later in 'Settings> Apps> Permissions.'
•For applications that have not been optimized for Marshmallow may not request permissions properly. In this case you will need to manually enable permissions for individual categories.
