Actually had phone in my hand, and phone was hijacked by remote hacker, i could see whoever it was, was trying to get my attention, as it clicked on settings, my home, scrolled down notification bar. I immediately turned off phone, disabled web connnections immediately on restart, and switched on no root firewall. then checked my email and he had sent the same message as the rest of you, at the same time as i powered down my phone, a failed email to myself. If he were able to do that, it is entirely possible your device has been compromised and data/images/vids/cam use etc may have been copied by the attacker. Currently doing an update to phone - 10 months late. Do your phone updates people asap.
