I have many applications installed on my Samsung Galaxy Tab 10.1. And it always download something from internet, in order to update and upgrade applications. It does it all the day and night, when I am in my home or business WiFi and when I am in mobile network.
How to disable this "feature"? I don't want any blind upgrades, only by my explicit permission.
Also, of course, I don't want to replace numerous downloads with numerous asks for permission.
