*not being able to send or receive texts when I am not connected to wifi at home, but if I use my data while out it chews up and I use GB in a minute.
*modified passwords
*authkitUI account?!?
*siri!!! Health!!! All disabled and yet I still record data and have to go in to each app and turn it off. Enables itself.
*voice over, tv remote, keyboard, braille whatever can control my apps is enabling on It's own.

*itunesu - wont let me access it.
my bank app had linked my email address as a form of payID
constant overheating
*battery drain
*cannot disable any location settings permanently it's never ending.
