I've been having a weird issue lately. Out the blue one day, my phone started displaying a message that the file "Start" cannot be opened because it is not trusted or signed. It does this when I get my home key on the front of the phone. It then says if the problem continues try to re install in it. Well, I hard reset my phone and it keep showing up, even without installing nothing else. Anyone have any ideas? I even flashed to the newest 28xxx standard rom and there it was that same message right after flashing. Also my phone seems to be running slower and locking up.
