Months ago, I uninstalled the Oxford Dictionary of Music. Today, it froze my phone, running Marshmallow, for a minute or so, until the window popped up telling me that it had stopped working and did I want to close it. This happens with this same app every week or so. It's not listed on my Disabled, Enabled, or System apps lists? Got any ideas of how I find this renegade bit and kill it for good?
