Not sure if this has been posted yet, if it has just delete my post. There's a new app in playstore called Adhell. Seems to work great so far it does not require root but does require admin access to use the builtin samsung firewall to block the ads. Also includes a package disabler but I have not used it yet. Best of all the app is free
