I downloaded Slacker Radio and it ended up as a system app, which I cannot uninstall. That really ticks me off. How did it end up a system app when I thought it was a user app? And how to uninstall it on my new Droid Turbo 2. I've seen a few threads recommending a download to remove system apps but I don't want to mess up and delete something required. Getting rid of the NFL app would be nice too.
