Phone kicks back to Hello screen from Home screen
So I have had a handful of iphone's that have had this particular problem.
Phone has been restored and boots to "Hello" screen.
After going through the setup process you get to the "Get started" screen.
Once you click "get Started" the phone will show the home screen then immediately go back to the hello screen.
Slide past "Hello" screen brings you to "get started" screen again instead of the normal set up process but once you click get started it will go back to "Hello".
Every now and again it will appear to try and reconnect to the activation server.
IMEI is clean.
