I want to watch Netflix on my Galaxy S3 but I don't want to allow it to hog my data plan. How can I ensure that it will ONLY run on Wifi? Is there an application I can download that will not allow certain apps to use 3G/4G?
Lots of ways... Personally I use LBE Privacy Guard, it asks you what permissions you want to allow whenever you install an app.. kinda like the BB does.... Requires root however...
