Why does application permission appear frequently in Galaxy S7/edge and Galaxy J(2016)?

Android 6.0 Marshmallow introduced a new permissions model with the addition of runtime permissions.

Until Android 5.x Lollipop, you had to accept all permissions (such as accessing camera, data network…) which an application asks for during the application installation procedure.

But from Android 6.0 Marshmallow, the pop-up for each permission appears when the application request to access that permission for the first time.

2.  Can I accept or deny each permission of the application?

From Android 6.0 Marshmallow, the option to allow or deny each permission of the application refers to below

1) Settings Apps: Settings > Applications > Application manager

2) Select the application which you want to change permissions

3) Tap “Permissions”

4) Changes the permissions which you want
