So I'm travelling to Mexico, and I got an International Data plan for that time. The "restrict background data" switch is good, but doesn't do what I want... I want to disable background data for everything except my work email app. How do I do this? I know you can disable ALL background data, but then I cannot enable it on specific apps. The other option is to disable it for every app I don't want to use individually, but that means I have to go thru EVERY app on my phone one-by-one. And then I would have to undo all that one-by-one... Is there a way to disable all background data EXCEPT for specific apps? Either thru Android, or maybe a third party app that batch disables all apps (individually, not the blanket switch) and then I can manually go back in and open up the 1 or 2 that I want to allow?
