A free program for Android, by Xingchen Rikka.
App Ops is a tool that allows you to easily view and manage all the permissions your application has been requesting. It also allows you to disable or enable the requested permissions, and even uninstall the app.
The application can be used on Android devices running Android 5.1 or higher, and will work even if the device is rooted. The only thing that you need to do is to install it, open it, and connect it to your ADB.
This tool is made with the intention of being used by the average user, so it is easy to use, and it is very intuitive.
