My 6+S did a weird reset after doing an iTunes restore from a 6+. It seems to be doing ok now. Going to give it some time to "settle in"
The 6+S gets hot, and i feel my display is not as good as the old 6+ as the new phone has dim corners.
I think there is a bit of a learning curve here, between the force touch, the new fingerprint sensor and the blazing speed of the phone it feels a little out of control.
It's a 6S Plus. Not a 6 Plus S
