Prevent certain apps from using mobile data

[Cherple]

Hi, I was previously an iPhone 5s user and just got my s6 not long ago. On my iPhone, there is a toggle where I can prevent certain apps from using ANY data at all, not just background data. Meaning if I were to switch that on for Facebook, when I open the Facebook app, and I'm not on wifi, it wouldn't be able to load anything at all.

I understand there's the restrict background data feature on the s6, I tested it and it will only restrict data when I'm not using the app. But if I were to open the app it will still use data. For example I would like to turn off data for my manga app, as I usually download the manga at home using wifi. But now everything I open the manga app it will use my data to download some images on the manga app.

Is there anyway I can completely prevent an app from using any Mobile data? It should prevent the app from using data even when it is open.

you can do it on android 6 i think. but if you are on android 5 there are apps like firewalls. if you are rooted try avast if not try this one.
