I am new to this board; I joined because I have a message that I can't figure out what to do with. Quite often now, my Galaxy S4 gives me this warning message: "An application attempted to access system on your device without authorization. This attempt has been blocked". When I tap on the message a box comes up that says: "Deleting applications from unauthorized sources may improve security". Under that message are two options: "Cancel" and "View applications". "Cancel" of course does nothing. "View applications" just opens the Applications Manager. My question: Is it possible to find out WHICH application is attempting to access "system" without permission? If I knew which application it was maybe I would uninstall it. As it is I have no idea which application is doing this and it would be too cumbersome for me to try deleting things one at a time hoping I hit the right one.
