Recently my family signed up for an offer from Google called Screenwise Select. As a part of the deal we got a smartphone used to connect to our TV and monitor TV shows that we watch. The phone is a Samsung Galaxy Player 5.0. However, evidently the Screenwise app is more than an app; it's taken over the phone. When I turn it on, the "swipe to unlock" appears for a split-second, then it flips over to this app. I can't get out if it. I suspect the system has been somehow modified so that the phone can only be used with the app.
So, my question is - is there a way to "root" but "not root" the phone - that is, to get the system back to normal with the app running like a regular app?
I think the app is in the AppStore so the other option is to factory reset the device and then install the app, but I don't want to do that without confirmation from the Screenwise people.
