Ive read a few things online this morning about the MTC app being malware or a virus, It doesn't show in your apps list however it was said that if it is a virus it might be piggy backing off something else installed on the phone and if you go into your settings-manage applications-go to ALL apps on top of your menu and go through the apps list you will come accross one that says email, one of those email ones is for Samsung Email, the very small icon of it says "WELCOME and fuck you for using Samsung Email" I would say that's enough to suggest it is some sort of virus not to be trusted, it was also mentioned somewhere else on the internet that it was attached to a samasung app, I had it come up on my phone but not sure how to remove it yet
