Being stuck with old phones has its advantages. My phone only runs CM7, which has this very same feature for some 2yrs. It's called app goggles or something.

Being stuck with old phones has its advantages. My phone only runs CM7, which has this very same feature for some 2yrs. It's called app goggles or something. I block internet access to lots of apps thatdo not need,it. And most of them crash when they try to use it. Eg. Swype tries to connect every time i reboot my phone. Not sure if they are just checking for updates or uploading my personal dict, but since it doesn't try to upload anything while I'm actually writing, i just watch it die every reboot and that is it. Almost all games i tried i removed access to see running apps and contact list. Very few crashed, meaning they probably expose those api to ads, and they are not using them yet.
