How about including in the Firewall the ability to manually allow or block an app from accessing the internet? This already exists in Norton Security for PC - why not in Norton Security for Mobile?
A related suggestion: How about a feature where when any app tries to access the internet for the first time after Norton Security is installed (or updated) that Norton Security asks the user whether allow or to block access to the internet for that app. This feature already exists in other Firewall apps.
