I have a question following up Locking applications to wifi only data connections:
I followed the guide given in its answer and notice some applications (like Android OS) don't have the option to be turned off. Is there any solution for this? At Data Usage the "app" called Android OS is using data but I don't wanna use data unless I'm on WiFi for that process.
What I'm trying to achieve (on the Xperia Z) is that on WiFi all apps have full access to the internet. On mobile data I only want Whatsapp and Gmail to be syncronised.
I disabled everything that uses data exept the mentioned apps above and I can't get
I also have My Data Manager installed. It says OS services is using 111kb so far, and it's going up. Another process called Android System has used 78kb.
In short again the question: some applications (like Android OS) don't have the option to be turned off in Data Usage. Is there a way to stop this process (and other processes) to use data unless I'm on WiFi?
