iPhones don't work out of the box? Millions of people using their devices right out of the box would disagree with that.

Go to the iPhone section of the forums here and there are lots of threads of people with camera problems (1), Bluetooth connection or skipping issues (2) with their iPhone 7 and 7plus.
