Okay, there's a problem. Many other apps are using mobile data when data is on. I don't want to restrict background data in Data Sense simply because I won't receive any WhatsApp messages/push notifications. However, when data is on...
-'System' has used 2MB in two days. What is this?
-Data to Restore, Transfer my Data, Outlook (sync is disabled) and Nokia Reading have all used <1MB. Why? I have never opened these apps in these two days.
-People, Battery app and my music app have all used <1MB. Once again, why? What do these apps have that need data connection? (note that my music app has ads, maybe that, but Battery does NOT)
By the way WhatsApp refuses to start when background data is disabled (Never) in Data Sense, meaning that I have to turn it off everytime I want to use it.
Microsoft need to wake up increase our control of which apps should use what data, like iOS. Anyway, why is there no third-party app yet to solve this?
