I find myself uninstalling every app unless I really need it and use it. It's amazing how many apps just sit around in your life over time. get them off your phone
Most people I've spoken with are either thinking "Apple/Google/Government would never allow apps to do something like that!" or they think "Everyone is already doing it so why bother trying to fight it. I'd only be inconveniencing myself for nothing"
That's the thing they don't just sit around, they all have run at start up and for Android I blame Google for not giving users the ability to block run at start up.
