I don't know what else to call it. I'm looking for a tool that can help me ferret out stuff that doesn't belong and maybe see what resources even legitimate apps think they should have access to. Sort of a security audit. Background: I'm old. My phone is a Samsung S4 (stop snickering). I mostly carry it for emergencies and taking the occasional photo or to use the calculator. I've installed very few apps on it myself (Opera Mini browser, a flashlight, the calculator, the Carista app for vehicle OBD). They've all been there for at least a year. This morning, when I took it out of the cradle, I noticed the lock screen had changed and, when unlocked, there was a window saying "Good Morning! Tell me, what's your (astrological) sign?" Yeah... Time to do some maintenance. What am I really looking for? I need to start coming to terms with this thing. My latest vehicle wants a phone to attach to, and there's legislation wending its way through State government that will allow the telcos to start shedding landlines.
